An aircraft catapult is a device used to help fixed-wing aircraft gain enough airspeed and lift for takeoff from a limited distance, typically from the deck of a ship . They are usually used on aircraft carrier flight decks as a form of assisted takeoff , but can also be installed on land-based runways , although this is rare.
74-630: USS Badoeng Strait was a Commencement Bay -class escort carrier of the United States Navy during the Korean War . The Commencement Bay class were built during World War II , and were an improvement over the earlier Sangamon class , which were converted from oil tankers . They were capable of carrying an air group of 33 planes and were armed with an anti-aircraft battery of 5 in (127 mm) , 40 mm (1.6 in) , and 20 mm (0.8 in) guns. The ships were capable of
148-465: A CATOBAR (Catapult Assisted Take Off But Arrested Recovery) configuration. U.S. Navy tactical aircraft use catapults to launch with a heavier warload than would otherwise be possible. Larger planes, such as the E-2 Hawkeye and S-3 Viking , require a catapult shot, since their thrust-to-weight ratio is too low for a conventional rolling takeoff on a carrier deck. Types previously or still operated by

The first attempt nearly killed Lieutenant Ellyson when the plane left the ramp with its nose pointing upward and it caught a crosswind, pushing the plane into the water. Ellyson was able to escape from the wreckage unhurt. On 12 November 1912, Lt. Ellyson made history as the Navy's first successful catapult launch, from
296-507: A month of flight training in preparation for another deployment to Korea. Badoeng Strait got underway on 15 September, bound for Korean waters. She stopped briefly in Pearl Harbor on 21 September and then continued on to Yokosuka , arriving there on 2 October. There, she joined Carrier Division 17 and became its flagship. She spent the next two months participating in anti-submarine training exercises held off Okinawa with other elements of

All other navies with aircraft carriers operate short take-off and vertical landing (STOVL) aircraft, such as the B variant of the Lockheed Martin F-35 Lightning II , the BAE Sea Harrier , and the AV-8B Harrier II . These aircraft can take off vertically with a light load, or use a ski jump to assist a rolling takeoff with
444-423: A small island. She had a complement of 1,066 officers and enlisted men. The ship was powered by two Allis-Chalmers geared steam turbines , each driving one screw propeller , using steam provided by four Combustion Engineering -manufactured water-tube boilers . The propulsion system was rated to produce a total of 16,000 shp (12,000 kW) for a top speed of 19 knots (35 km/h; 22 mph). Given

Likewise the Wright Brothers beginning in 1904 used a weight and derrick styled catapult to assist their early aircraft with a takeoff in a limited distance. On 31 July 1912, Theodore Gordon Ellyson became the first person to be launched from a U.S. Navy catapult system. The Navy had been perfecting
592-509: A stationary coal barge. On 5 November 1915, Lieutenant Commander Henry C. Mustin made the first catapult launch from a ship underway. The US Navy experimented with other power sources and models, including catapults that utilized gunpowder and flywheel variations. On 14 December 1924, a Martin MO-1 observation plane flown by Lt. L. C. Hayden was launched from USS Langley using a catapult powered by gunpowder. Following this launch, this method
666-502: A submarine would launch a small number of floatplanes for offensive operations or artillery spotting, to be recovered by the submarine once the aircraft has landed. The first launch off a Royal Navy battlecruiser was from HMAS Australia on 8 March 1918. Subsequently, many Royal Navy ships carried a catapult and from one to four aircraft; battleships or battlecruisers like HMS Prince of Wales carried four aircraft and HMS Rodney carried two, while smaller warships like
740-595: A territory subsequently claimed by Germany as New Swabia . All of Lufthansa 's catapult ships were taken over by the Luftwaffe in 1939 and used as seaplane tenders in World War II along with three catapult ships built for the military. After World War II, Supermarine Walrus amphibian aircraft were also briefly operated by a British whaling company, United Whalers. Operating in the Antarctic, they were launched from
814-652: A top speed of 19 knots (35 km/h; 22 mph), and due to their origin as tankers, had extensive fuel storage. She was named after the Badung Strait , located between the Indonesian islands of Bali and Nusa Besar , which was the site of a World War II battle in February 1942, between American– Netherlands and Japanese naval forces. In 1941, as United States participation in World War II became increasingly likely,

Other forms have been used historically, such as mounting a launching cart holding a seaplane on a long girder-built structure mounted on
962-547: The Heinkel Flugzeugwerke to launch mail-planes. These ships served the route between Germany and the United States. The aircraft, carrying mail–bags, would be launched as a mail tender while the ship was still many hundreds of miles from its destination, thus speeding mail delivery by about a day. Initially, Heinkel He 12 aircraft were used before they were replaced by Junkers Ju 46 , which were in turn replaced by
1036-540: The 7th Fleet . In December, she returned to Korea to join a blockade of North Korean ports. Over the following days, her aircraft took part in a number of operations in western North Korea. She returned to Yokosuka on 28 December for replenishment and then carried out patrols in the Yellow Sea between 7 January 1952 and 6 February. The Australian carrier HMAS Sydney replaced her that month, allowing Badoeng Strait to return to San Diego. She stopped in Pearl Harbor on
1110-626: The Battle of Chosin Reservoir in late November and into December. The ship withdrew to the Sea of Japan on 10 December to replenish fuel, ammunition, and stores while underway. Three days later, she had returned to Wonsan to cover the Hungnam evacuation over the course of 15–24 December. The following day, she refueled at sea and then moved into the Yellow Sea by 27 December, where her aircraft operated over Seoul, which
1184-626: The Commencement Bay -class ships were not large enough to operate these new aircraft, the Navy had begun to replace them with the much larger Essex -class aircraft carriers by the mid-1950s. Proposals to radically rebuild the Commencement Bay s either with an angled flight deck and various structural improvements or lengthen their hulls by 30 ft (9.1 m) and replace their propulsion machinery to increase speed came to nothing, as they were deemed to be too expensive. On 14 January 1957, she left San Diego for Bremerton , Washington, where she
1258-594: The Commencement Bay s were built as carriers from the keel up. Their general layout was similar to the Sangamon -class escort carriers , but some of the Sangamon's engineering shortcomings were addressed. They entered service late in World War II – USS Commencement Bay launched on 9 May 1944 – so most of them saw little or no operational service. Thirty-five of them were ordered but many were cancelled prior to completion. Nineteen saw commissioned service in

Ford -class aircraft carriers, and a similar system has also been developed for the Chinese People's Liberation Army Navy 's Type 003 aircraft carrier . Historically it was most common for seaplanes to be catapulted, allowing them to land on the water near the vessel and be hoisted on board, although in

These were carried out at Eniwetok and the Bikini Atoll . Badoeng Strait provided air transport from the fleet to Bikini, supported the Marine helicopter unit HMH-363 , and served as a radiation safety checkpoint. Her crew also assisted with construction projects ashore. ON 31 July, she got underway for San Diego, arriving on 8 August. Late

They proved to be the most successful of the escort carriers, and the only class to be retained in active service after the war, since they were large enough to operate newer aircraft. Badoeng Strait was 557 ft 1 in (169.80 m) long overall , with a beam of 75 ft (23 m) at

She assisted a marine unit south of Wonsan that came under attack on 28 October from a North Korean division that had been bypassed by the main UN offensive. The ship next provided aerial support to the US 7th Infantry Division as it advanced toward Kapsan and Pungsan near

#17330932901181628-583: The Second World War (before the advent of the escort carrier ) conventional fighter aircraft (notably the Hawker Hurricane ) would sometimes be catapulted from " catapult-equipped merchant " (CAM) vessels to drive off enemy aircraft, forcing the pilot to either divert to a land-based airstrip , or to jump out by parachute or ditch in the water near the convoy and wait for rescue. Aviation pioneer and Smithsonian Secretary Samuel Langley used
1702-897: The Todd-Pacific Shipyard in Tacoma , Washington. She was renamed Baedoeng Strait and was launched on 15 February 1945, after which she was moved to the Commercial Iron Works for fitting-out work. She was commissioned into active service on 14 November 1945, by which time World War II had ended. Badoeng Strait then underwent additional work to modify her to serve as a flagship , after which she sailed for San Diego , California, for her shakedown cruise and initial training. There, she carried out air qualification training with her new aircrew. She got underway again in late March 1946, bound for Pearl Harbor , which she reached on 2 April. She then returned to California on 20 April, where she
1776-532: The US Navy embarked on a construction program for escort carriers , which were converted from transport ships of various types. Many of the escort carrier types were converted from C3-type transports , but the Sangamon -class escort carriers were instead rebuilt oil tankers . These proved to be very successful ships, and the Commencement Bay class , authorized for Fiscal Year 1944, were an improved version of
1850-557: The Vought V-85G . German airline Lufthansa subsequently used dedicated catapult ships SS Westfalen , MS Schwabenland , Ostmark and Friesenland to launch larger Dornier Do J Wal (whale), Dornier Do 18 and Dornier Do 26 flying boats on the South Atlantic airmail service from Stuttgart, Germany to Natal, Brazil. On route proving flights in 1933, and a scheduled service beginning in February 1934, Wals flew
1924-512: The dock landing ship Gunston Hall to refuel that vessel. The two ships collided during refueling, but neither was damaged seriously. Badoeng Strait arrived in Kobe on 31 July and unloaded equipment before sortieing on 4 August to begin combat operations in the Tsushima Strait . The following day, one of VMF-323's Vought F4U Corsair fighters crashed on landing, injuring the pilot and destroying
1998-512: The factory ship FF Balaena , which had been equipped with an ex-navy aircraft catapult. The Chinese, Indian, and Russian navies operate conventional aircraft from " short take-off but arrested landing " (STOBAR) aircraft carriers. Instead of a catapult, they use a ski jump to assist aircraft in taking off with a positive rate of climb. Carrier aircraft such as the J-15 , Mig-29K , and Su-33 rely on their own engines to accelerate to flight speed. As

Badoeng Strait then went to sea for anti-submarine training off Okinawa, and after a week there, joined the rest of 7th Fleet for operations off Japan that lasted through September. The ship finally sortied from Sasebo for combat operations on 5 October, though this time, her activities were limited to providing anti-submarine patrols for various naval units in
2294-511: The British carrier HMS Glory . She arrived at Sasebo on 5 February 1953, unloaded equipment, and then proceeded to Yokosuka on 7 February, arriving two days later. On 11 February, she left for California, ending her operations in the Korean War. She earned six battle stars for her service during the conflict. Badoeng Strait reached San Diego on 27 February; the following month, she moved to

Two elevators transferred aircraft from the hangar to the flight deck . The first fifteen ships of the Commencement Bay class were ordered on 23 January 1943, allocated to Fiscal Year 1944. The ship, originally to have been named San Alberto Bay , was laid down on 18 August 1944, at
2590-431: The Royal Navy was developing a new catapult system for their fleet of carriers. Commander C. C. Mitchell , RNV , recommended a steam-based system using a slotted cylinder as an effective and efficient means to launch the next generation of naval aircraft. Trials on HMS Perseus , flown by pilots such as Eric "Winkle" Brown , from 1950 showed its effectiveness. Navies introduced steam catapults, capable of launching
2664-495: The San Francisco Naval Shipyard for an extensive overhaul and modernization that lasted for six months. She then returned to San Diego to be placed in limited commissioned, allocated to the reserve fleet there. She was placed in full commission again in February 1954. For the next year, she carried out anti-submarine training, including tests of the new Grumman S-2 Tracker anti-submarine aircraft and of helicopters in

During the cruise, she visited Japan, patrolled off the coast of China, and took part in anti-submarine exercises with elements of 7th Fleet. She visited Taiwan and Okinawa in September before steaming back across the Pacific, arriving in San Diego on 1 October. From there, she moved back to San Francisco for another three months of mainentance. The ship returned to San Diego in February 1956, and thereafter departed to join several ships in

The U.S. Navy's Gerald R. Ford -class aircraft carriers and PLA Navy's Type 003 aircraft carrier included electromagnetic catapults in their design. From 1929, the German Norddeutscher Lloyd -liners SS Bremen and Europa were fitted with compressed air-driven catapults designed by

From September 1934, Lufthansa had a support ship at each end of the trans-ocean stage, providing radio navigation signals and catapult launchings after carrying aircraft out to sea overnight. From April 1935 the Wals were launched directly offshore, and flew the entire distance across the ocean. This was possible as the flying boats could carry more fuel when they did not have to take off from
3626-406: The following month, she took part in extensive amphibious assault training, which lasted for fifteen weeks and included joint operations with Marine helicopters. The exercises also tested helicopter assaults and helped to develop air assault doctrine. By the late 1950s, Badoeng Strait was worn out, and was too small to accommodate new jet aircraft and assault helicopters entering service. Because

Her aircraft supported Allied forces as they fought their way inland from Incheon from 14 to 22 September, before stopping in Incheon to replenish fuel and ammunition. After four days, Badoeng Strait got underway again to take part in the operation into the Seoul area, which culminated in
3922-459: The late 1990s–early 2000s, the bridle catchers were removed from the first three Nimitz -class aircraft carriers. USS Enterprise was the last U.S. Navy operational carrier with the ramps still attached before her inactivation in 2012. Like her American counterparts, the French aircraft carrier Charles De Gaulle is not equipped with bridle catchers because the modern aircraft operated on board use

Linear induction motors have been experimented with before, such as Westinghouse's Electropult system in 1945. However, at the beginning of the 21st century, navies again started experimenting with catapults powered by linear induction motors and electromagnets . Electromagnetic catapult would be more energy efficient on nuclear-powered aircraft carriers and would alleviate some of

She operated out of San Diego for the next six months before moving to Naval Air Station Alameda on 16 June, where she took on a contingent of 223 Naval Reserve Officers Training Corps cadets for a training cruise. The Korean War broke out on 25 June 1950, when North Korea invaded the South, and the United Nations intervened two days later. Badoeng Strait
4218-453: The pilots survived. Badoeng Strait then briefly left to refuel and rearm at Sasebo , Japan, before resuming operations on 15 August. She and her sister ship Sicily provided further support to the 1st Marine Brigade until 23 August. Badoeng Strait was then detached to cover the withdrawal of the British destroyer HMS Comus , which had been damaged by North Korean aircraft. The carrier's fighters provided combat air patrol over
