78-519: A howitzer motor carriage M8 – an M3 tank with a larger turret – and trials indicated that a 75 mm gun on the M5 light tank development of the M3 was possible. The M3/M5 design was dated though, and the 75 mm gun reduced storage space. The T7 light tank design, which was initially seen as a replacement, grew in weight to more than 25 short tons, taking it out of the light tank classification, and so
117-493: A 38 mm thick gun mantlet . The glacis plate was 25 mm thick. Side hull armor thickness varied: the frontal section was 25 mm thick but the rear third of the armor (which covered the engine compartment) was only 19 mm. A new lightweight 75 mm gun was developed, a derivative of the gun used in the B-25H Mitchell bomber . The gun had the same ballistics as the 75 mm M3 in use by American tanks but used

273-470: A new light tank weighing 14 short tons (13 t) armed with a 37mm gun protected by up to 38 mm (1.5 in) of armor and with a "low silhouette" which was passed to Ordnance Department with building of two pilot vehicles carried out by Rock Island Arsenal . For comparison purposes the first (T7) was to be of welded hull and cast turret with VVSS suspension, the second (T7E1) of rivetted hull, composite cast and welded turret and HVSS. Riveted construction
312-446: A thinly walled barrel and different recoil mechanism. The design featured 16 in (41 cm) tracks and torsion bar suspension, similar to the slightly earlier M18 Hellcat tank destroyer , which itself started in production in July 1943. The torsion bar system was to give a smoother ride than the vertical volute suspension used on most US armored vehicles. At the same time, the chassis
351-519: Is equal to the present Medium Tank Company and can perform missions now assigned to them when defiladed from anti-tank and heavy artillery fire. It can furnish strong fire support either direct or indirect. In a more open type of terrain and enemy situation, such as may be expected on the larger land masses, this company, due to its great mobility combined with strong fire power, will provide excellent reconnaissance, protection of flanks, covering force, as well as direct assault or support by fire. This company
390-589: Is preserved in the Greek Army Tank Museum. One is on display outside the village of Metsovo (Μέτσοβο). Additionally, the M38 Wolfhound prototype armored car was experimentally fitted with an M24 turret. In 1972, the Norwegian Army decided to retain 54 of their 123 M24 light tanks as reconnaissance vehicles after they were substantially rebuilt under the designation NM-116 . It was calculated that
429-545: Is the principal element of the battalion which gives it its flexibility to meet rapidly changing situations. 711th Tank Battalion notes , Battle of Okinawa , Page 26 of 41 The M24 was virtually the only tank that the U.S. Far East Command could immediately dispatch to the Korean Peninsula at the time of the Korean War. During the same period, there were a total of four tank battalions (71st, 77th, 78th, and 79th) under

These were then issued to Troop F, 2nd Cavalry Reconnaissance Squadron and Troop F, 42nd Cavalry Reconnaissance Squadron, which each received seventeen M24s. During the Battle of the Bulge in December 1944, these units and their new tanks were rushed to the southern sector; two of the M24s were detached to serve with the 740th Tank Battalion of
507-750: The Battle of Dien Bien Phu . In December 1953, ten disassembled Chaffees were transported by air to provide fire support to the garrison. They fired about 15,000 shells in the long siege that followed before the Viet Minh forces finally overcame the camp in May 1954, almost all being entirely worn out and badly damaged by the time the battle was over. France also deployed the M24 in Algeria , with some variants which fought there carrying an AMX-13 turret modified by France. Some former French and US Chaffees are known to have been passed down to
546-572: The M41 Walker Bulldog was developed as a replacement, M24s were not mostly removed from U.S. and NATO armies until the 1960s and remained in service with some Third World countries. British combat experience in the North African campaign identified several shortcomings of the M3 Stuart light tank, especially the performance of its 37 mm cannon . A 75 mm gun was experimentally fitted to
585-632: The Norwegian Home Guard and used in the defense of the former Fornebu Airport from 1974 well into the 1980s. The Chilean Army up-gunned their M24s in the mid-1980s to the IMI-OTO 60 mm hyper velocity medium support (HVMS) gun, with roughly comparable performance to a standard 90 mm gun. Chile operated this version until 1999. Uruguay continues to use the M24, modernized with new engines and 76 mm guns which can fire armor-piercing, fin stabilized, discarding sabot (APFSDS) rounds. In
624-558: The Ordnance Corps , together with Cadillac (who manufactured the M5), started work on the new project, designated Light Tank T24 . The powerplant and transmission of the M5 were used together with some aspects of the T7. Efforts were made to keep the weight of the vehicle under 20 tons. The armor was extremely light and was sloped to maximize effectiveness . The turret armor was 25 mm thick with
663-574: The U.S. First Army . The M24 started to enter widespread use in December 1944, but they were slow in reaching the front-line combat units. By the end of the war, the light tank companies of many armored divisions were still mainly equipped with the M3/M5 Stuart. Some armored divisions did not receive their first M24s until the war was over. Aside from the US Army, the British Army was another main user of
702-413: The 75 mm main gun, which was a vast improvement over the 37 mm. The M24 was inferior in armor to German tanks, but the bigger gun at least gave its crews a much better chance to fight back when it was required, especially in infantry support. The M24's light armor made it vulnerable to virtually all German tanks, anti-tank guns, and hand-held anti-tank weapons. The contribution of the M24 to winning
741-615: The Army of South Vietnam, where they saw service at least until the Battle of Huế , with several serving as fixed gun emplacements outside vital military installations such as airbases. The last time the M24 is known to have been in action was in the Indo-Pakistani War of 1971 , where 66 Pakistani Chaffees stationed in East Pakistan (today's Bangladesh ) were lost to Indian Army T-55s , PT-76s , and anti-tank teams, being easy prey for
780-643: The British Army Medium Tank M7 The M7 medium tank, initially T7 light tank, was an American tank, originally conceived as an up-gunned replacement for the M3/M5 light tank ("Stuart") . The project developed to mount the same 75mm armament as the M4 Sherman while retaining the light weight and maneuverability of the M3 Stuart; however, during development the weight of the prototype surpassed
819-603: The Chaffee during the war, with at least several hundred obtained through the US Lend-Lease program. These saw action mainly in northwestern Europe and the North German Plain where British forces saw action against German troops. Reports from the armored divisions that received them prior to the end of hostilities were generally positive. Crews liked the improved off-road performance and reliability, but were most appreciative of

#1732891265861858-465: The Far East Command, and each battalion maintained one company composed of M24s for the purpose of defending Japan's narrow road network and bridges. The first battle took place on 10 July 1950, when A Company of the 78th Tank Battalion, assigned to the 24th Infantry Division, fought a North Korean tank and destroyed it while losing two. The M24's 75 mm main gun lacked penetration power against
897-502: The Korean Peninsula, suffered heavy damage, with only two of the 14 tanks remaining in about a month. This unfavorable situation was resolved in August of the same year when U.S. medium tanks were finally deployed on the Korean Peninsula. All of the tanks units that operated the M24s were replaced with the M4A3E8. Afterward, the M24 was given to the reconnaissance squadron under the tank battalion or
936-477: The NM-116 rebuilding program cost only about a third as much as contemporary light tanks. This program was managed by the firm Thune-Eureka . The American firm NAPCO developed an improved power pack based around the 6V53T diesel engine used in the M113 armored personnel carrier mated to an Allison MT-653 transmission. The original 75 mm Gun M6 L/39 was replaced with a French D-925 90 mm low pressure gun, with
975-673: The U.S. from 1950 until 1970. The M24s initially were organized in two Tank Regiments numbered 392 and 393. In later years the Tank Regiments were reorganized in Tank Battalions with the same numbers. From 1962 till the early seventies the M24s in Tank Battalions were replaced with M47s and the M24s were used to equip Independent Reconnaissance Companies with an additional 121 M24s received from Italy in 1975. From 1991 till 1995 61 M24s were scrapped due to CFE Treaty limitations. The rest are abandoned in or outside military camps and one M24
1014-619: The US Army's standard for light tanks and crossed into the medium tank category and was renamed. The M7 had significantly less armor than the M4 Sherman, no greater firepower, and held only a slight advantage in top speed. For these reasons, and because the M4 was already battle-tested and in full production, the M7 was cancelled in 1943. In January 1941, the Armored Force prepared a list of characteristics for
1053-587: The armor protection to 63 mm (2.5 in) maximum took the weight to 25 short tons (23 t). A more apt classification was thus given by OCM 18522, dated 6 August 1942, which standardized the T7E5 as the M7 medium. An order for 3,000 M7s to start in November 1942 was placed with International Harvester . Test revealed that the produced vehicles were heavier than anticipated at 28 to 29 short tons (25 to 26 t) fully stowed. This reduced performance and production
1092-523: The better-equipped invading Indian forces. Although both Iran and Iraq had M24s prior to the Iran–Iraq War , there is no report of their use in that conflict. South Korean Chaffees saw limited service during the Korean War, often performing hit-and-run raids on communist forces. Cambodia, Laos, Japan and Taiwan were four other Asian nations to have operated Chaffees aside from South Vietnam, South Korea and Pakistan. The Greek Army received 85 M24s from
1131-429: The designation Light Tank M24 . It was produced at two sites; from April at Cadillac and from July at Massey-Harris . By the time production was stopped in August 1945, 4,731 M24s had been produced. The M24 Chaffee was intended to replace the ageing and obsolete Light Tank M5 ( Stuart ) , which was used in supplementary roles. European theater The first 34 M24s reached Europe in November 1944 and were issued to
1170-508: The frontal armor of the T-34-85. In addition, the armor of the M24 could be penetrated by the main guns of enemy tanks, artillery, and even anti-tank rifles used by the North Korean military. Moreover, most of the tanks dispatched from Japan had not been repaired for a long time, so turrets and main guns frequently broke down during battles. A Company of the 78th Tank Battalion, who first arrived on
1209-481: The infantry division for most of the period and was used for scouting purposes as it should have been. Like other successful World War II designs, the M24 was supplied to many armies around the globe and was used in local conflicts long after it had been replaced in the US Army by the M41 Walker Bulldog . France employed its M24s in Indo-China in infantry support missions, with good results. They employed ten M24s in

1248-551: The mid-1950s, in an attempt to improve the anti-tank performance of the vehicle, some French M24s had their turrets replaced with those of the AMX-13 light tank. AMX-13 variants with Chaffee turrets also existed. In the late-1960s, the JSDF modified a single M24 with four Type 64 ATGMs in order to improve its anti-tank capabilities. Former operators : Background: British armoured fighting vehicle production during World War II , Tanks in
1287-549: The performance was considered inferior to the M4A3 medium tank . The six modified vehicles and the remaining seven were accepted as M7 mediums bringing the total run to 13 tanks. Thus production acceptance records show only a total of seven tanks. A proposal to re-engine with a Ford V-8, as the M7E1, was initiated but cancelled in July 1943 and the M7 was declared obsolete at the end of 1943. At least one M7 medium tank survives to this day. It
1326-641: The war in Europe was minor, as too few arrived too late to replace the worn-out M5s of the armored divisions. At the end of WWII, the US Army displayed its Chaffees alongside the British Comet tanks and the Soviet IS-3 heavy tank, in the Berlin Victory Parade in 1945. Pacific theater The (Light Tank) company, equipped with M24 Light Tanks, is an essential element in any tank battalion. In fire power it

In British service it was given the service name Chaffee after the United States Army general , Adna R. Chaffee Jr. , who helped develop the use of tanks in the United States armed forces . Although
1404-615: Was designated as the Medium Tank M7 . The weight increase without increased power gave it unsatisfactory performance; the program was stopped in March 1943 to allow standardization on a single medium tank – the M4 medium. This prompted the Ordnance Committee to issue a specification for a new light tank, with the same powertrain as the M5A1 but armed with a 75 mm gun. In April 1943,
1443-517: Was expected to be a standard used for other vehicles, such as self-propelled guns, and specialist vehicles; known together as the "light combat team". It had a relatively low silhouette and a three-man turret. On 15 October 1943, the first pilot vehicle was delivered. The design was judged a success and a contract for 1,000 was immediately raised by the Ordnance Department. This was subsequently increased to 5,000. Production began in 1944 under
1482-443: Was halted until it could be rectified. Analysis of the problem indicated that it was caused by castings being thicker than specified. Six of the production tanks were then modified to use the lightest castings possible and their power trains were revised to improve performance. The modified vehicles were referred to as M7E2s in some documents. Testing of the modified vehicles revealed improved performance but only at lower speeds and that
1521-416: Was recognized as obsolete and the vehicle was never completed but used to test the transmission and suspension. Three further vehicles (T7E2 to T7E4) with different engine and transmission combinations were ordered during development. A change of armament to include the 57mm gun T2 and, at the request of Armored Force, the 75mm M3 followed. Increasing the length of the hull increased the weight but increasing
