Question: Which fighter plane, also flown by United States Marine Corps World War 2 fighter ace Donald N. Aldrich, held the longest production run of any piston-engine fighter in U.S. history?
Context: Donald Nathan Aldrich (24 October 1917 – 3 May 1947) was a United States Marine Corps Reserve captain and World War II flying ace.  With 20 victories, Aldrich was the fifth-highest-scoring Marine Corps ace of the war.  He joined the Royal Canadian Air Force after the United States Army Air Corps refused him because he was married.  Aldrich became an instructor pilot and transferred to the United States Marine Corps in late 1942.  He joined VMF-215 in the Solomon Islands campaign in June 1943, flying the Vought F4U Corsair.  Aldrich added to his 20 victories in three combat tours with six probables, the highest total number of probables in the Marine Corps.  Postwar, Aldrich continued to serve in the Marine Corps and was killed in a 1947 plane crash. Kenneth Ambrose Walsh (November 24, 1916 – July 30, 1998) was a United States Marine Corps lieutenant colonel and a Medal of Honor recipient who was the fourth ranking fighter ace in World War II with a record of 21 enemy planes destroyed.  He also served in Korea during the first year of the Korean War and retired from the Marine Corps in February 1962. Marine Fighter Training Squadron 401 (VMFT-401) is a United States Marine Corps Reserve fighter squadron flying the F-5N Tiger II.  Known as the "Snipers", the squadron is the only adversary squadron in the Marine Corps, also is the first and only reserve squadron in the Marine Corps tasked to act as the opposing force in simulated air combat.  They are based at Marine Corps Air Station Yuma and fall under the command of the 4th Marine Aircraft Wing and Marine Aircraft Group 41.  VMFT-401 is a non-deployable unit. 3rd Battalion, 3rd Marines, abbreviated as (3/3), is an infantry battalion of the United States Marine Corps, based out of Kāne'ohe, Hawai'i.  Known as either "Trinity" or "America's Battalion", the unit falls under the command of the 3rd Marine Regiment of the 3rd Marine Division.  The unit consists of approximately 1124 U.S. Marines and United States Navy sailors.  Like most battalions of the U.S. Marine Corps, 3rd Battalion, 3rd Marines is made up of three rifle companies (India, Kilo, and Lima), a Headquarters and Services (H&S) company, and a weapons company.  The battalion was originally formed at Marine Corps Base Camp Lejeune, North Carolina in 1942 and saw action on both Bougainville and Guam during World War II, where it was awarded the first of its Presidential Unit Citations for "gallantry, determination, and esprit de corps in accomplishing its mission under extremely difficult and hazardous conditions"; and the first of its Navy Unit Commendations for "outstanding service".  Marines in the battalion were also awarded one Medal of Honor and seven Navy Crosses during the war.  Following World War II, 3rd Battalion was disbanded until 1951, when it was reformed in California.  The battalion was alerted for possible deployment during the 1956 Suez War and the 1958 intervention in Lebanon.  In 1965, the Marines of 3rd Battalion were deployed to the Vietnam War and participated in Operation Starlite, the first major Marine engagement of that conflict.  The battalion continued to see major action through Vietnam and was rotated back to the United States in 1969.  Famous alumni from its time in Vietnam include Corporal Robert Emmett O'Malley, the first Marine in Vietnam to be awarded the Medal of Honor, Oliver North, and John Ripley.  Around the end of the Vietnam War, the Battalion was deactivated for a second time in 1974. 3d Light Antiaircraft Missile Battalion (3d LAAM Bn) was a United States Marine Corps air defense unit equipped with the medium range surface-to-air MIM-23 HAWK Missile System.  During World War II, the battalion was known as the 3rd Defense Battalion and took part in combat operations at Pearl Harbor, Midway, Guadalcanal and Bougainville.  The unit was deactivated in late 1944 but was brought back into service as the Marine Corps began to transition to surface to air missiles for their air defense needs in the early 1950s.  During the mid to late 1950s, the battalion was based at Marine Corps Training Center 29 Palms, California and was one of two Marine Corps units that operated the land-based version of the RIM-2 Terrier Missile.  In January 1963 3d LAAM battalion was moved to Marine Corps Air Station Cherry Point, North Carolina and would eventually fall under the command of Marine Air Control Group 28 (MACG-28) and the 2nd Marine Aircraft Wing (2nd MAW).  3d LAAM Battalion's final combat tour saw it providing air defense for the Marine Corps area of operations during Operation Desert Shield/Desert Storm.  3d LAAM Battalion was deactivated on 30 September 1994 as part of the post-Cold War draw down of forces and because the Marine Corps had made the decision to divest itself of its medium-range air defense. The Douglas SBD Dauntless was a World War II American naval scout plane and dive bomber that was manufactured by Douglas Aircraft from 1940 through 1944.  The SBD ("Scout Bomber Douglas") was the United States Navy's main carrier-borne scout plane and dive bomber from mid-1940 through mid-1944.  The SBD was also flown by the United States Marine Corps, both from land air bases and aircraft carriers.  The SBD is best remembered as the bomber that delivered the fatal blows to the Japanese carriers at the Battle of Midway in June 1942.  The type earned its nickname "Slow But Deadly" (with the SBD initials) during this period. John Franklin Bolt (19 May 1921 – 8 September 2004) was a naval aviator in the United States Marine Corps and a decorated flying ace who served during World War II and the Korean War.  He remains the only U.S. Marine to achieve ace status in two wars and was also the only Marine jet fighter ace.  He rose to the rank of lieutenant colonel during his military career. The Vought F4U Corsair is an American fighter aircraft that saw service primarily in World War II and the Korean War.  Demand for the aircraft soon overwhelmed Vought's manufacturing capability, resulting in production by Goodyear and Brewster: Goodyear-built Corsairs were designated FG and Brewster-built aircraft F3A.  From the first prototype delivery to the U.S. Navy in 1940, to final delivery in 1953 to the French, 12,571 F4U Corsairs were manufactured, in 16 separate models, in the longest production run of any piston-engined fighter in U.S. history (1942–53). The Austin-Ball A.F.B.1 (Austin Fighting Biplane) was a British fighter plane of the First World War, built by the Austin Motor Company with design input from Britain's leading fighter ace at the time, Albert Ball.  Although trials with the prototype were on the whole excellent, and it could very probably have been developed into a useful operational type, the A.F.B.1 did not go into production, as both Austin's production capacity and its Hispano-Suiza engine were required for the S.E.5a. The North American F-82 Twin Mustang was the last American piston-engine fighter ordered into production by the United States Air Force.  Based on the P-51 Mustang, the F-82 was originally designed as a long-range escort fighter in World War II.  The war ended well before the first production units were operational.
