The National Museum of the Mighty Eighth Air Force is a non-profit organization with a museum facility located in Pooler, Georgia , in the western suburbs of Savannah . It educates visitors through the use of exhibits, artifacts, archival materials, and stories, most of which are dedicated to the history of the Eighth Air Force of the United States Army Air Corps that served in the European Theatre during World War II .
92-580: Among the many World War II exhibits are aircraft including a B-17 Flying Fortress bomber that can be viewed while being restored, a model of a Messerschmitt Bf 109G fighter, and a 3/4-scale model of a P-51 Mustang fighter. Aircraft on display outside include the B-47 Stratojet , MiG-17 , and F-4 Phantom II from the post-WWII Cold War era. Planning for a museum dedicated to the Eighth Air Force began in 1983. Thirteen years later, on 14 May 1996,
184-521: A "/R" suffix, smaller modifications on the production line or during overhaul, such as equipment changes, were made with kits of pre-packaged parts known as Umrüst-Bausätze , usually contracted to Umbau and given a "/U" suffix. Field kits known as Rüstsätze were also available but those did not change the aircraft designation. Special high-altitude interceptors with GM-1 nitrous oxide injection high-altitude boost and pressurized cockpits were also produced. The newly fitted Daimler-Benz DB 605 A engine
276-558: A 40 percent increased high explosive and incendiary effect). The MG FF and FF/M saw widespread use in fighters such as the Bf 109 E-3 to F-1, Bf 110 C to F, and Fw 190 A-1 to A-5. Early variants of the Fw 190 (A-1 to A-5) were typically fitted with an inboard pair of MG 151 and an outboard pair of MG FF/M, although the MG FF/M were sometimes removed in the field in order to save weight. The MG FF/M fed from
368-570: A 60-round drum that required an underwing bulge to fit within the wing (90 rounds in the A-5). From the A-6 onward, the MG FF/M were replaced by a pair of MG 151/20 feeding from 125 round belts, or deleted altogether. The cannon was also fitted to bombers such as the Do 217 , Ju 88 , He 111 , Do 17 , as well as many other aircraft, either as aerial defense, or more often for anti-ship and defensive fire suppression. Although
460-579: A camera installation behind the cockpit. The E-5 was a reconnaissance variant of the E-3, the E-6 was a reconnaissance variant of the E-4/N. Twenty-nine E-5s were built and nine E-6s were ordered. The E-7 was the next major production variant, entering service and seeing combat at the end of August 1940. One of the limitations of the earlier Bf 109Es was their short range of 660 km (410 mi) and limited endurance, as
552-761: A defensive weapon, in both fixed and flexible format. It saw widespread use in those roles by the German Luftwaffe , particularly during the early stages of World War II , although from 1941 onwards it was gradually replaced by the Mauser firm's 20 mm MG 151/20 , which had both a higher rate of fire and muzzle velocity . One major disadvantage of the MG FF cannon was its extremely low ammunition count. One cannon only carried 90 bullets, and these were fired very quickly. MG FF stands for Maschinengewehr Flügel Fest , which translates into "machine gun, wing, fixed"; this reflects
644-469: A dream, the non plus ultra . Of course, everyone wanted to fly it as soon as possible." The Bf 109A was the first version of the Bf 109. Armament was initially planned to be just two cowl-mounted 7.92 mm (.312 in) MG 17 machine guns . However, possibly due to the introduction of the Hurricane and Spitfire , each with eight 7.7 mm (.303 in) machine guns, experiments were carried out with
736-472: A drop tank from October 1940. Early E-7s were fitted with the 1,100 PS DB 601A or 1,175 PS DB 601Aa engine, while late-production ones received 1,175 PS DB 601N engines with improved altitude performance – the latter was designated as E-7/N. A total of 438 E-7s of all variants were built. Bf 109E variants and sub-variants Prior to the war, the Kriegsmarine had become fascinated with
828-458: A large fuel line that ran up and along the inside starboard wall of the cockpit, with a clear sight glass located in the fuel line's main span so the pilot could easily see the flow of fuel and know when the tank was empty. Alternatively, a bomb could be fitted and the E-7 could be used as a Jabo fighter-bomber. Previous Emil subtypes were progressively retrofitted with the necessary fittings for carrying
920-469: A metal shield was fitted over the left hand banks to deflect exhaust fumes away from the supercharger air-intake. The supercharger air-intake was, from the F-1 -series onwards, a rounded, "elbow"-shaped design that protruded further out into the airstream. A new three-blade, light-alloy VDM propeller unit with a reduced diameter of 3 m (9 ft 8.5 in) was used. Propeller pitch was changed electrically, and
1012-421: A new, enlarged supercharger in the high-altitude DB 605AS engine, a larger vertical stabilizer (G-5 onwards), and MW 50 power boost in 1944. Erich Hartmann , the world's top scoring fighter ace, claiming 352 victories, flew only the Bf 109G, of which he said: It was very manoeuvrable, and it was easy to handle. It speeded up very fast, if you dived a little. And in the acrobatics manoeuver, you could spin with
SECTION 10
#17330938608141104-451: A pressurized cockpit. It could be identified by the small, horn-shaped air intake for the cockpit compressor just above the supercharger intake, on the left upper cowling. In addition, the angled armour plate for the pilot's head was replaced by a vertical piece which sealed-off the rear of the side-hinged cockpit canopy. Small, triangular armour-glass panels were fitted into the upper corners of this armour, although there were aircraft in which
1196-408: A projectile with thinner walls that allowed increased explosive charge. This projectile was lighter and thus had a higher muzzle velocity than the previous ammunition; this also entailed that it generated less recoil than earlier projectiles requiring a modification of the recoil mechanism. With this modification it could fire the new mine shell, but accidentally using the heavier MG FF ammo could damage
1288-428: A rate of fire of c. 540 rounds per minute. AP, HE and incendiary projectiles were also available (115 to 117 g projectiles, 585 m/s, c. 520 rpm) because the mine-shot was not capable of holding incendiary or tracer parts. There were also different types of high-explosive mine shell fillings with either standard Pentrit A ( PETN + Aluminium ), a mixture called HA 41 ( RDX + Aluminium powder)(the latter had
1380-422: A tail-hook, catapult fittings and increasing the wingspan to 11.08 m (36.35 ft). The ailerons were increased in span, as were the slats, and flap travel was increased. The wings were not modified to be folding since the ship Graf Zeppelin was designed around the intended aircraft, so the lifts could accommodate the Bf 109T with its 11 m (36 ft) wingspan. The wings could, however, be detached from
1472-487: A third machine gun firing through the propeller shaft. V4 and some A-0 were powered by a 640 PS (631 hp, 471 kW) Junkers Jumo 210 B engine driving a two-blade fixed- pitch propeller, but production was changed to the 670 PS (661 hp, 493 kW) Jumo 210D as soon as it became available. The A-0 was not of a uniform type; there were several changes in their appearance. Visible changes included engine, cockpit and machine gun ventilation holes/slats, and
1564-621: Is listed as having produced only four Bf 109Ds, probably the D-0 preproduction series with the serial production transferred to the licensed manufacturers. Several Bf 109Ds were sold to Hungary. Switzerland bought 10 109D-1s (Serial Numbers from 2301 until 2310) which had been built by the Arado-Flugzeugwerke GmbH factory located in Warnemünde. In late 1938, the Bf 109E entered production. To improve on
1656-608: The Bf 109D was the standard version of the Bf 109 in service with the Luftwaffe just before the start of World War II. Despite this, the type saw only limited service during the war, as all of the 235 Bf 109Ds still in Luftwaffe service at the beginning of the Polish Campaign were rapidly taken out of service and replaced by the Bf 109E, except in some night fighter units where some examples were used into early 1940. Variants included
1748-564: The D-0 and D-1 models, both having a Junkers Jumo 210D engine and armed with two wing-mounted and two nose-mounted 7.92 mm (.312 in) MG 17s. The D-2 was an experimental version with an engine-mounted machine gun, but as previously tried, this installation failed. The D-3 was similar to the C-3 but with two 20 mm MG FFs in the wings. A total of 647 Bf 109Ds of all versions were built by Focke-Wulf, Erla, Fieseler, Arado and AGO. Messerschmitt
1840-605: The F-4 onward, the new 20 mm Mauser MG 151/20 with 200 rounds was used as the Motorkanone . The first F-4s reached frontline units in June 1941. Production lasted exactly a year between May 1941 and May 1942, with 1,841 of all F-4 variants produced. Some of the later models were capable of mounting two 20 mm MG 151/20 cannons under the wing in faired gondolas with 135 rpg. These were designated F-4/R1 and 240 of them were produced by WNF in
1932-519: The Hispano-Suiza HS.404 – which had been developed from the larger Oerlikon FF S – the MG FF had some disadvantages, such as low rate of fire and low muzzle velocity , as well as limited ammunition storage in its drums. On the other hand, it was much lighter and shorter. Even with its compact size, wing installation on the Messerschmitt Bf 109 and Focke-Wulf Fw 190 fighters was not easy, as

#17330938608142024-564: The M -Shell, it was intended to replace the HEI grenade. When the projectile broke up, the phosphorus remained in effective parts in the target and burned for a long time. The prerequisite for disintegration of the projectile were sufficiently resistant targets, namely armour plates of at least 3 mm at 45°, at least 4.5 mm at 60°, at least 7 mm at 75°, at least 15 mm at 90°, impact angle; also aircraft components (strong spars and struts). The incendiary effect against protected containers
2116-671: The National Museum of the Mighty Eighth Air Force in March 2013. Messerschmitt Bf 109G Due to the Messerschmitt Bf 109 's versatility and time in service with the German and foreign air forces, numerous variants were produced in Germany to serve for over eight years with the Luftwaffe . Additional variants were produced abroad totalling in 34,852 Bf 109s built. "The 109 was
2208-580: The V10 prototype, was identical to the V8, except for its Jumo 210G engine. The V10, V11 , V12 and V13 prototypes were built using Bf 109B airframes, and tested the DB 600A engine with the hope of increasing the performance of the aircraft. The DB 600A was dropped as the improved DB601A with direct fuel injection was soon to become available. Developed from the V10 and V13 prototypes,
2300-490: The trapeziform wing shape from the E-1, but the span was reduced by 61 cm (2 ft) by "clipping" the tips. Otherwise the wings incorporated the cooling system modifications described below. V22 also became the testbed for the pre-production DB 601E. The smaller wings had a detrimental effect on the handling so V23 , Stammkennzeichen (factory Code) CE+BP , W.Nr 5603, was fitted with new, semi- elliptical wingtips , becoming
2392-478: The 1,475 PS Daimler-Benz DB 605 driving a three-blade VDM 9-12087A variable-pitch propeller with a diameter of 3 m (9.8 ft) with even broader blades than used on the F-series. Pitch control, as on the 109F, was either electro-mechanical (automatic) or manual-electric using a thumb-switch on the throttle lever. From 1944 a new high-altitude propeller with broader blades was introduced, designated VDM 9-12159, and

If you took off too fast it would turn [roll] ninety degrees away. We lost a lot of pilots in takeoffs. From the Bf 109 G-5 on an enlarged wooden tail unit (identifiable by a taller vertical stabilizer and rudder with a morticed balance tab, rather than
2576-419: The 15 mm Mauser MG 151 cannon with 200 rounds. As the harder-hitting 20 mm Mauser MG 151/20 version became available, a number of F-2s were retrofitted with it in the field. About 1,230 F-2s were built between October 1940 and August 1941 by AGO, Arado, Erla, Messerschmitt Regensburg and WNF(Wiener Neustädter Flugzeugwerke). No tropical version was built, although F-2s were fitted with sand filters in
2668-590: The 670 PS (661 hp, 493 kW) Jumo 210D engine driving a two-bladed fixed-pitch propeller. During the production run a variable-pitch propeller was introduced and often retrofitted to older aircraft; these were then unofficially known as B-2 s. The Bf 109B saw combat with the Legion Condor during the Spanish Civil War , although it was apparent that the armament was still inadequate. Several aircraft were produced with an engine-mounted machine gun but it
2760-444: The 7.92 mm (.312 in) MG 17 were replaced with 13 mm (.51 in) MG 131 machine guns ( G-5 onwards) due to the latter's much larger breechblock , and on the wings (due to larger tyres), leading to the Bf 109 G-6's nickname "Die Beule" ("The Bulge"). The Bf 109G continued to be improved: new clear-view cockpits, greater firepower in the form of the 30 mm (1.18 in) MK 108 cannon were introduced in late 1943; and
2852-489: The Bf 109T consisted of two 7.92 mm (.312 in) MG 17s above the engine and one 20 mm MG FF/M cannon in each wing. Interest in Graf Zeppelin revived when the value of aircraft carriers became obvious, and in 1942 the ship was back in the yards for completion. By this time, the Bf 109T was hopelessly outdated and a new fighter would be needed. Messerschmitt responded with the updated Me 155A series, but work on

2944-412: The DB 601 E was not yet available in numbers, the pre-production F-0 (the only F variant to have a rectangular supercharger intake) and the first production series F-1/F-2 received the 1,175 PS (1,159 hp, 864 kW) DB 601N engine driving a VDM 9-11207 propeller. The F-0/F-1 and F-2 only differed in their armament; the F-1 being fitted with one 20 mm MG FF/M Motorkanone firing through
3036-483: The E was developed. A boundary layer duct allowed continual airflow to pass through the airfoil above the radiator ducting and exit from the trailing edge of the upper split flap. The lower split flap was mechanically linked to the central "main" flap, while the upper split flap and forward bath lip position were regulated via a thermostatic valve which automatically positioned the flaps for maximum cooling effectiveness. In 1941 "cutoff" valves were introduced which allowed
3128-557: The E-4/N; owing to priority being given to equipping Bf 110s with this engine, one fighter gruppe was converted to this version, starting in July 1940. The E-4 was also available as a fighter-bomber with equipment very similar to the previous E-1/B. It was known as E-4/B (DB 601Aa engine) and E-4/BN (DB 601N engine). A total of 561 of all E-4 versions were built, including 496 E-4s built as such: 250 E-4, 211 E-4/B, 15 E-4/N and 20 E-4/BN. The E-5 and E-6 were both reconnaissance variants with
3220-453: The E-7 with a 300-litre drop tank, double the range, to 1,325 km (820 mi). The canopy stayed much the same as that of the E-4, although the handbook for the 'F' stipulated that the forward, lower triangular panel to starboard was to be replaced by a metal panel with a port for firing signal flares. Many F-1s and F-2s kept this section glazed. A two-piece, all-metal armour plate head shield
3312-508: The Erla Maschinenwerke. Production of the short-lived Bf 109C began in the spring of 1938. The 109C was powered by a 700 PS (690 hp, 515 kW) Jumo 210G engine with direct fuel injection. Another important change was a strengthened wing, now carrying two more machine guns, giving four 7.92 mm (.312 in) MG 17s in total. The C-0s were pre-production aircraft, the C-1
3404-400: The MG FF was often replaced with the 20 mm MG 151/20 from 1941 onwards, it saw a comeback in 1943 as the primary Schräge Musik gun in the Bf 110 (and other) night fighters, as it fit perfectly into the rear cockpit, and muzzle velocity was less important in this application (there were also stocks of surplus guns and ammunition to be used up). As soon as it hit the outer skin of
3496-576: The Mighty Eighth Air Force Museum opened to the public. A 2003 statute named the museum as the official State of Georgia center for character education. The museum received a B-17 project from the National Air and Space Museum in January 2009. In February 2011, a fire truck that was used at Hunter Army Airfield during World War II was donated to the museum. The museum changed its name to
3588-505: The Soviet Union for a closer inspection. 6–15 incorporated several improvements from the Bf 109B production program and had been prepared to use a variable-pitch propeller although it had not been installed. According to RLM documentation 22 aircraft were ordered and delivered with V4 as the A-series prototype. The first Bf 109 in serial production, the Bf 109 B-1 , was fitted with
3680-492: The V14 was armed with two 7.92 mm (.312 in) MG 17s above the engine and one 20 mm MG FF in each wing, the V15 was just fitted with the two MG 17s mounted above the engine. After test fights, the V14 was considered more promising and a pre-production batch of 10 E-0 was ordered. Batches of both E-1 and E-3 variants were shipped to Spain for evaluation, and first saw combat during

As an indestructible body, it remained effective even after penetrating several bulkheads. In combination with

3864-615: The angled shape) was often fitted. This tail unit was standardised on G-10 s and K-4 s. Although the enlarged tail unit improved handling, especially on the ground, it weighed more than the standard metal tail unit and required that a counterweight was fitted in the nose, increasing the variant's overall weight. With the Bf 109G, a number of special versions were introduced to cope with special mission profiles. Here, long-range fighter-reconnaissance and high-altitude interceptors can be mentioned. The former were capable of carrying two 300 L (80 US gal) drop tanks, one under each wing; and
3956-407: The design was originally conceived as a short-range interceptor. The E-7 rectified this problem as it was the first Bf 109 subtype to be able to carry a drop tank , usually the standardized Luftwaffe 300 L (80 US gal) capacity unit mounted on a centre-line rack under the fuselage, which increased its range to 1,325 km (820 mi). Fuel from the drop tank was pumped to the internal fuel tank via
4048-453: The designation of the aircraft . Instead the "/R" suffix referred to the G-2's Rüstzustand or equipment condition of the airframe, which was assigned at the factory rather than in the field. There were two Rüstzustand planned for G-2s: MG FF cannon The MG FF was a drum-fed, blowback-operated , 20 mm aircraft autocannon , developed in 1936 by Ikaria Werke Berlin of Germany. It
4140-404: The drum required substantial space, and as a consequence the ammunition storage was initially reduced to 60 shells per drum. An ammunition drum of 90-round nominal capacity was developed for the Fw 190 A-5, and retrofitted to some earlier variants. There were also experiments with belt feedings. The MG FF was adapted to fire a new type of high-capacity, high-explosive " mine shell " that featured
4232-434: The earlier Bf 109 E, the Bf 109 F was much improved aerodynamically. The engine cowling was redesigned to be smoother and more rounded. The enlarged propeller spinner, adapted from that of the new Messerschmitt Me 210 , now blended smoothly into the new engine cowling. Underneath the cowling was a revised, more streamlined oil cooler radiator and fairing. A new ejector exhaust arrangement was incorporated, and on later aircraft
4324-418: The effect of counterbalancing the extra weight and length of the DB 601, which drove a heavier three-bladed Vereinigte Deutsche Metallwerke (VDM)-made propeller. To incorporate the new radiators, the wings were almost completely redesigned and reinforced, with several inboard ribs behind the spar being cut down to make room for the radiator ducting. Because the radiators were mounted near the trailing edge of
4416-424: The engine would have created extra weight and drag, negating some of the performance gains afforded by the increased power, so it was decided to move the main radiators to the undersurfaces of the wings immediately outboard of the junction of the wing root and wing panel, just forward of the trailing edges' inner ends, leaving the oil cooler under the nose in a small, streamlined duct. The new radiator position also had
4508-444: The engine; the combined effect being enough to cause structural failure at the rear fuselage–fin attachment point. Initially, two external stiffening plates were screwed onto the outer fuselage on each side, and later the structure was reinforced. The wing was redesigned, the most obvious change being the new quasi-elliptical wingtips, and the slight reduction of the aerodynamic area to 16.05 m (172.76 ft²). Other features of
4600-473: The fact that in Luftwaffe practice guns of 20 mm or less were designated as "machine guns" ( maschinengewehr ) as opposed to larger "machine cannons", or autocannons, which were "MK", for maschinenkanone . The "wing, fixed" part reflects the fact that the primary motivation behind its design was to create a 20 mm caliber weapon that was compact and light enough to be mounted in the wings of aircraft, especially fighters. Compared to rival designs, such as
4692-487: The field. The maximum speed of the F-1 and F-2 was 615 km/h (382 mph) at rated altitude. The 1,350 PS (1,332 hp, 993 kW) DB 601 E was used in the F-3 and F-4 model together with a VDM 9-12010 propeller with broader blades for improved altitude performance. The DB 601 E was initially restricted to 1,200 PS (1,184 hp, 883 kW) at 2,500 rpm; however, the full rating of 1,350 PS at 2,500 rpm

#17330938608144784-564: The final phases of the Spanish Civil War. The E-1 production version kept two 7.92 mm (.312 in) MG 17s above the engine and two more in the wings. Later, many were modified to the E-3 armament standard. The E-1B was a small batch of E-1s that became the first operational Bf 109 fighter bomber, or Jagdbomber (usually abbreviated to Jabo ). These were fitted with an ETC 500 bomb rack, carrying either one 250 kg (550 lb) bomb or four 50 kg (110 lb) bombs. The E-1
4876-520: The first quarter of 1942. This optional additional armament was standardized as field kit for later G and K series. A special high-altitude variant, the F-4/Z featuring GM-1 boost, was also built with a production run of 544 in the first quarter of 1942 and saw extensive use. Finally, the Erla factory produced 576 tropicalized F-4 trop in the first half of 1942. With its initial engine rating of 1,200 PS,
4968-460: The first year of operation, and this output was initially banned by VT-Anw.Nr.2206, forcing Luftwaffe units to limit maximum power output to 1,310 PS (1,292 hp, 964 kW) at 2,600 rpm and 1.3 atm manifold pressure (38.9 inches/4.4 lbs). The full output was not reinstated until 8 June 1943 when Daimler-Benz issued a technical directive. Up to 1944, the G-series was powered by
5060-544: The forward engine cowlings. A less obvious difference was the omission of the boundary layer bypass outlets, which had been a feature of the F-series, on the upper radiator flaps. Like most German aircraft produced in World War II, the Bf 109 G-series was designed to adapt to different operational tasks with greater versatility; larger modifications to fulfil a specific mission task, such as long-range reconnaissance or long-range fighter-bomber, were with "Rüststand" and given
5152-503: The fuselage for transport purposes, as in every version of the Bf 109. Following flight tests, especially the catapult tests, 70 T-1 with DB601Ns were to be produced at Fieseler in Kassel, but after seven T-1s were built, the carrier project was cancelled. The remaining 63 of 70 T-1s were built as T-2 s without carrier equipment and some of the T-1s may have been "upgraded" to T-2 standard. It
5244-467: The gun. In the interest of avoiding such errors, the weapon was redesignated the MG FF/M. It was introduced with the Bf 109 E-4 and Bf 110 C-4 in summer 1940. The MG FF fired a 134 g projectile with a muzzle velocity of some 600 m/s and a rate of fire of about 530 rounds per minute. The MG FF/M fired a 90 g HE/M (high explosive mine shell) projectile with a muzzle velocity of c. 700 m/s and
5336-596: The idea of the aircraft carrier . Borrowing ideas from the British and Japanese (mainly Akagi ), they started the construction of Graf Zeppelin as part of the rebuilding of the navy. The air group for the carrier was settled on Messerschmitt Bf 109T fighters and Ju 87C dive bombers. The suffix 'T' denotes Träger (carrier) in German use. Despite references to a Bf 109 T-0 version, this version never existed. Seven earlier versions (Bf 109 B, Bf 109 C, Bf 109 E) were converted to test carrier equipment. This included adding
5428-405: The latter received pressurized cockpits for pilot comfort and GM-1 nitrous oxide "boost" for high altitudes. The latter system, when engaged, was capable of increasing engine output by 223 kW (300 hp) above the rated altitude to increase high-altitude performance. The G-1 , produced from February 1942, was the first production version of the G-series and the first production Bf 109 with
5520-537: The location of the oil cooler was changed several times to prevent overheating. Many of these Bf 109 A-0 served with the Legion Condor and were often misidentified as B-series aircraft, and probably served in Spain with the tactical markings 6-1 to 6–16 . One A-0, marked as 6–15 , ran out of fuel and was forced to land behind enemy lines. It was captured by Republican troops on 11 November 1937 and later transferred to
5612-498: The maximum speed of the F-4 (and F-3) was 635 km/h (394 mph) at rated altitude; and with the clearance of the full rating of 1,350 PS, maximum speed increased to 659 km/h (410 mph) at 6,200 m (20,341 ft). The Bf 109 G-series was developed from the largely identical F-series airframe, although there were detail differences. Modifications included a reinforced wing structure, an internal bullet-proof windscreen,

#17330938608145704-454: The performance afforded by the 441–515 kW (600–700 PS) Jumo 210, the larger, longer Daimler-Benz DB 601 A engine was used, yielding an extra 223 kW (300 PS) at the cost of an additional 181 kg (400 lb). A much bigger cooling area was needed to disperse the extra heat generated by the DB 601, and this led to the first major redesign of the basic airframe. Enlarging the existing nose-mounted radiator sufficiently to cool
5796-401: The pilot to shut down either wing radiator in the event of one being damaged; this allowed the remaining coolant to be preserved and the damaged aircraft returned to base. The valves were delivered to frontline units as kits, the number of which, for unknown reasons, was limited. The cutoff valves were later factory standard fitting for the Bf 109 G and K series. The armament of the Bf 109 F
5888-427: The plate was solid steel. Silica gel capsules were placed in each pane of the windscreen and opening canopy to absorb any moisture which may have been trapped in the double glazing . The last 80 G-1s built were lightweight G-1/R2 . In these GM-1 nitrous oxide 'boost' was used, and the pilot's back armour was removed, as were all fittings for the long-range drop tank. A few G-1 flown by I./JG 1 are known to have carried
5980-576: The propeller hub, with 60 rounds. The F-1 first saw action in the Battle of Britain in October 1940 with JG 51. The most experienced fighter aces like Werner Mölders were the first ones to fly Bf 109 F-1s in combat in October 1940. A total of 208 F-1s were built between August 1940 and February 1941 by Messerschmitt Regensburg and the Wiener Neustädter Flugzeugwerke (WNF). The F-2 introduced
6072-456: The redesigned wings included new leading edge slats , which were slightly shorter but had a slightly increased chord ; and new rounded, removable wingtips which changed the planview of the wings and increased the span slightly over that of the E-series. Frise-type ailerons replaced the plain ailerons of the previous models. The 2R 1 profile was used with a thickness-to-chord ratio of 14.2% at
6164-407: The root reducing to 11.35% at the last rib. As before, dihedral was 6.53°. The wing radiators were shallower and set farther back on the wing. A new cooling system was automatically regulated by a thermostat with interconnected variable position inlet and outlet flaps that would balance the lowest drag possible with the most efficient cooling. A new radiator, shallower but wider than that fitted to
6256-619: The ship was again canceled and the Me 155 was later re-purposed as a high-altitude interceptor. Design work was transferred to Blohm & Voss and the aircraft was then known as the BV 155 . The Bf 109Ts were issued to several training units in 1943. Then, in April 1943, the Jagdstaffel Helgoland was formed and operated from Düne until late 1943, when the unit transferred to Lista in south Norway. The unit
6348-469: The single centreline Motorkanone gun as an improvement. With the early tail unit problems out of the way, pilots generally agreed that the F series was the best-handling of all the Bf 109 series. Mölders flew one of the first operational Bf 109 F-1s over England from early October 1940; he may well have been credited with shooting down eight Hurricanes and four Spitfires while flying W.No 5628 , Stammkennzeichen SG+GW between 11 and 29 October 1940. As
6440-431: The standard wing planform for all future Bf 109 combat versions. The fourth prototype, V24 VK+AB , W.Nr 5604, flew with the clipped wings but featured a modified, "elbow"-shaped supercharger air-intake, which was eventually adopted for production, and a deeper oil cooler bath beneath the cowling. On all of these prototypes, the fuselage was cleaned up and the engine cowling modified to improve aerodynamics. Compared to
6532-544: The underwing 20 mm MG 151/20 cannon gondolas. The G-2 , which started production in May 1942, lacked the cabin pressurization and GM-1 installation. Performance-wise it was identical to the G-1. The canopy reverted to one layer of glazing and incorporated the angled head armour used on the F-4, although several G-2 had the vertical type as fitted to the G-1. Several Rüstsätze could be fitted, although installing these did not change
6624-407: The use of heavier, welded framing for the cockpit transparencies, and additional light-alloy armour for the fuel tank. It was originally intended that the wheel wells would incorporate small doors to cover the outer portion of the wheels when retracted. To incorporate these the outer wheel bays were squared off. Two small inlet scoops for additional cooling of the spark plugs were added on both sides of
6716-565: The wing, coinciding with the increased speed of the airflow accelerating around the wing camber , cooling was more effective than that of the Jumo engined 109s, albeit at the cost of extra ducting and piping, which was vulnerable to damage. The lowered undercarriage could throw up mud and debris on wet airfields, potentially clogging the radiators. To test the new 1,100 PS (1,085 hp, 809 kW) DB 601A engine, two more prototypes ( V14 and V15 ) were built, each differing in their armament. While
6808-635: Was a derivative of the Swiss Oerlikon FF F cannon (its FF suffix indicating Flügel Fest , for a fixed-mount, wing location from the Swiss original), with the Oerlikon FF design itself a development of the Imperial German World War I Becker 20 mm cannon , and was designed to be used in space-limited, fixed mountings such as inside aircraft wings, although it saw use as both an offensive and
6900-424: Was a development of the DB 601E engine utilised by the preceding Bf 109 F-4; displacement and compression ratio were increased as well as other detail improvements to ease large-scale mass production. Takeoff and emergency power of 1,475 PS (1,455 hp, 1,085 kW) was achieved with 1.42 atm (42.5 inches/6.17 lbs) of boost at 2,800 rpm. The DB 605 suffered from reliability problems during
6992-421: Was added, as on the E-4, to the hinged portion of the canopy, although some lacked the curved top section. A bullet-resistant windscreen could be fitted as an option. The fuel tank was self-sealing and around 1942 Bf 109 Fs were retrofitted with additional armour made from layered light-alloy plate just aft of the pilot and fuel tank. The fuselage body aft of the canopy barely changed in its externals. The rudder
7084-771: Was also fitted with the Reflexvisier "Revi" gunsight. Communications equipment was the FuG 7 Funkgerät 7 (radio set) short-range radio apparatus, effective to ranges of 48–56 km (30–35 mi). A total of 1,183 E-1 were built, 110 of them were E-1/B. Only very limited numbers of the E-2 variant were built, for which the V20 prototype served as basis. It was armed with two wing-mounted, and one engine-mounted Motorkanone MG FF cannon, which gave considerable trouble in service, as well as two synchronized MG 17s cowl machine guns. In August 1940, II./ JG 27
7176-498: Was also revised to an easier-to-produce, "squared-off" design, which also helped improve the pilot's field of view. This canopy, which was also retrofitted to many E-1s and E-3s, was largely unchanged until the introduction of a welded, heavy-framed canopy on the G series in the autumn of 1942. The E-4 would be the basis for all further Bf 109E developments. Some E-4 and later models received a further improved 1,175 PS (1,159 hp, 864 kW) DB601N high-altitude engine; known as
7268-434: Was attacked by a Spitfire during a test flight. While making an evasive manoeuvre, the wings broke away and Balthasar was killed in the crash. Slightly thicker wing skins and reinforced spars dealt with the wing problems. Tests were also carried out to find out why the tails had failed and it was found that at certain engine settings a high-frequency oscillation in the tailplane spar was overlapped by harmonic vibrations from
7360-491: Was cleared for service use by February 1942. The DB 601 E ran on standard 87 octane "B-4" aviation fuel, despite its increased performance; while the earlier DB 601 N required 100 octane "C-3" fuel. Only 15 examples of the F-3 are believed to have been produced by Messerschmitt Regensburg between October 1940 and January 1941. Like the F-1, the F-3 was armed with the 20 mm MG-FF/M and two 7.92 mm (.312 in) MG 17s. From
7452-450: Was fitted and the main undercarriage legs were raked forward by six degrees to improve the ground handling. An unexpected structural flaw of the wing and tail section was revealed when the first F-1s were rushed into service; some aircraft crashed or nearly crashed, with either the wing surface wrinkling or fracturing or by the tail structure failing. In one accident, the commander of JG 2 "Richthofen", Wilhelm Balthasar , lost his life when he
7544-410: Was fitted to high-altitude variants with the DB 605AS or D-series engines. The early versions of the Bf 109G closely resembled the Bf 109 F-4 and carried the same basic armament; however, as the basic airframe was modified to keep pace with different operational requirements, the basically clean design began to change. From the spring of 1943, the G-series saw the appearance of bulges in the cowling when
7636-521: Was found that the performance of the T-2 was closely comparable to the E-4/N and, because of its ability to take off and land in shorter distances, these fighters were assigned to I/JG.77 , deployed in Norway on landing strips which were both short and subject to frequent, powerful cross-winds. At the end of 1941 the unit was ordered to return their aircraft to Germany and received E-3s as replacements. The armament of
7728-434: Was made using drawn steel (the same way brass cartridges are made) instead of being cast as was the usual practice. This resulted in a shell with a thin but strong wall, which had a larger cavity in which to pack a much larger explosive charge than was otherwise possible. The new shell required modifications to the MG FF's mechanism due to the different recoil characteristics, hence the MG FF/M designation. The cockpit canopy
7820-431: Was operating this type. To improve the performance of the Bf 109E, the last two real prototypes ( V16 and V17 ) were constructed. These received some structural improvements and more powerful armament. Both were the basis of the Bf 109 E-3 version. The E-3 was armed with the two MG 17s above the engine and one MG FF cannon in each wing. A total of 1,276 E-3 were built, including 83 E-3a export versions. The E-3
7912-428: Was regulated by a constant-speed unit, though a manual override was still provided. Thanks to the improved aerodynamics, more fuel-efficient engines and the introduction of light-alloy versions of the standard Luftwaffe 300-litre drop tank, the Bf 109 F offered a much increased maximum range of 1,700 km (1,060 mi) compared to the Bf 109 E's maximum range figure of 660 km (410 miles) on internal fuel and with
8004-720: Was renamed as 11./JG 11 as of 30 November 1943 and the Bf 109Ts remained in operation until the summer of 1944, after which some were used in training units in Germany. Development of the new Bf 109 F airframe had begun in 1939. After February 1940, an improved engine, the Daimler-Benz DB 601E , was developed for use with the Bf 109. The engineers at the Messerschmitt facilities took two Bf 109 E-1 airframes and installed this new powerplant. The first two prototypes, V21 ( Werknummer (Works number) or W.Nr 5602) and V22 (W.Nr 1800) kept
8096-515: Was replaced by the E-4 (with many airframes being upgraded to E-4 standards starting at the beginning of the Battle of Britain ), which was different in some small details, most notably by using the modified 20 mm MG-FF/M wing cannon and having improved head armour for the pilot. With the MG FF/M, it was possible to fire a new and improved type of explosive shell, called Minengeschoß (or 'mine-shell'), which
8188-403: Was revised and consisted of the two synchronized 7.92 mm (.312 in) MG 17s with 500 rpg above the engine plus a Motorkanone firing through the propeller hub. The pilots' opinion on the new armament was mixed: Oberst Adolf Galland criticised the light armament as inadequate for the average pilot, while Major Walter Oesau preferred to fly a Bf 109 E and Oberst Werner Mölders saw
8280-530: Was slightly reduced in area and the symmetrical fin airfoil section changed to an asymmetrical airfoil shape, producing a sideways lift force that swung the tail slightly to the left. This helped increase the effectiveness of the rudder and reduced the need for right rudder on takeoff to counteract torque effects from the engine and propeller. The conspicuous bracing struts were removed from the horizontal tailplanes which were moved to slightly below and forward of their original positions. A semi-retractable tailwheel
8372-506: Was the production version, and the C-2 was an experimental version with an engine-mounted machine gun. The C-3 was planned with 20 mm MG FF cannons replacing the two MG 17s in the wings, but it is not known how many C-3s (if any) were built or converted. The C-4 was planned to have an engine-mounted Motorkanone MG FF, but this variant was not produced. A total of 58 Bf 109Cs of all versions were built by Messerschmitt. The next model,
8464-401: Was very unreliable, most likely because of engine vibrations and overheating. Thus the Bf 109 V8 was constructed to test the fitting of two more machine guns in the wings; however, results showed that the wing needed strengthening. In the following V9 prototype, both wing guns were replaced by 20 mm MG FF cannons. A total of 341 Bf 109 B-1s were built by Messerschmitt, Fieseler , and
