The Douglas BTD Destroyer is an American dive/torpedo bomber developed for the United States Navy during World War II. A small number had been delivered before the end of the war, but none saw combat.
On 20 June 1941, the United States Navy placed an order with the Douglas Aircraft Company for two prototypes of a new two-seat dive bomber to replace both the Douglas SBD Dauntless and the new Curtiss SB2C Helldiver, designated XSB2D-1. [1] The resulting aircraft, designed by a team led by Ed Heinemann, was a large single-engined mid-winged monoplane. It had a laminar flow gull-wing, and unusually for a carrier-based aircraft of the time, a tricycle undercarriage. It was fitted with a bomb bay and underwing racks for up to 4,200 lb (1,900 kg) of bombs or one torpedo (typically the Mark 13), while defensive armament consisted of two wing-mounted 20 mm (0.79 in) cannon and two remote-controlled turrets, each with two .50 in (12.7 mm) machine guns. [2]
The prototype first flew on 8 April 1943, demonstrating good performance, being faster than the Dauntless and capable of carrying more bombload, but it was heavier and more complex. [3] The U.S. Navy had made a request for a new torpedo bomber developed from the XSB2D-1. Douglas reworked the XSB2D-1 by removing the turrets and second crewman, while adding more fuel and armor, while wing racks could carry not just one but two torpedoes, producing the BTD-1 Destroyer. The orders for the SB2D-1 were converted to the BTD-1, with the first BTD-1 flying on 5 March 1944. [4] The BTD-1 was heavier than the XS2BD-1 and had poorer performance. Ed Heinemann asked for cancellation of the BTD-1. [5]
The first production BTD-1s were completed in June 1944. By the time Japan surrendered in August 1945, only 28 aircraft had been delivered, and production was cancelled due to performance, along with other aircraft types that had been designed from the start as single-seaters, such as the Martin AM Mauler. [6] None saw combat. In any event, Heinemann and his team were already working on developing the single-seat BT2D that became the Douglas A-1 Skyraider.
One of the two XSB2Ds was destroyed in a crash on 10 January 1946. [7]
United States 
BTD-1 Destroyer, Bureau Number 04959, was under restoration for display at the Wings of Eagles Discovery Center, Elmira-Corning Regional Airport, Elmira, New York. [8] This aircraft had long been in the Florence Air & Missile Museum collection until the museum's closing in 1997. In September 2015 the aircraft was relocated to the Hixson Flight Museum in Rome, Georgia, where it is undergoing restoration. [9] [10]

The Aichi D3A is a World War II carrier-borne dive bomber. It was the primary dive bomber of the Imperial Japanese Navy (IJN) and was involved in almost all IJN actions, including the attack on Pearl Harbor.
The Douglas A-1 Skyraider is an American single-seat attack aircraft in service from 1946 to the early 1980s, which served during the Korean War and Vietnam War. The Skyraider had an unusually long career, remaining in frontline service well into the Jet Age ; thus becoming known by some as an "anachronism". The aircraft was nicknamed "Spad", after the French World War I fighter.
The Douglas TBD Devastator was an American torpedo bomber of the United States Navy. Ordered in 1934, it first flew in 1935 and entered service in 1937. At that point, it was the most advanced aircraft flying for the Navy; however, by the time of the US entry into World War 2, the TBD was already outdated.
The Douglas XTB2D Skypirate was a torpedo bomber intended for service with the United States Navy's Midway- and Essex-class aircraft carriers; it was too large for earlier decks. Two prototypes were completed, but the dedicated torpedo bomber was becoming an outdated concept, and with the end of World War II, the type was deemed unnecessary and cancelled.
The Consolidated TBY Sea Wolf was a United States Navy torpedo bomber of World War II. It was designed by Vought but entered service and was manufactured by Consolidated Aircraft due to high demand for production lines. A competitor and contemporary to the Grumman TBF Avenger, both were designed to replace the older TBD Devastator but the Sea Wolf was subject to substantial delays and never saw combat in WW2. The design was developed a bit further, with a large Navy order for 1100, but only 180 of the TBY-2 type were built before cancellation after VJ Day. An order of 600 for the TBY-3 was also stopped.
The Aichi B7A Ryusei was a large and powerful carrier-borne torpedo-dive bomber produced by Aichi Kokuki for the Imperial Japanese Navy Air Service during the Second World War. Built in only small numbers and deprived of the aircraft carriers it was intended to operate from, the type had little chance to distinguish itself in combat before the war ended in August 1945.
The Douglas SBD Dauntless is a World War II American naval scout plane and dive bomber that was manufactured by Douglas Aircraft from 1940 through 1944. The SBD was the United States Navy's main carrier-based scout/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" during this period.
The Nakajima B5N was the standard carrier-based torpedo bomber of the Imperial Japanese Navy (IJN) for much of World War II. It also served as a high level bomber.
The Douglas A2D Skyshark was an American turboprop-powered attack aircraft built by the Douglas Aircraft Company for the United States Navy. The program was substantially delayed by engine reliability problems, and was canceled because more promising jet attack aircraft had entered development and the smaller escort carriers the A2D was intended to utilize were being phased out.
The Kyūshū Q1WTōkai was a land-based anti-submarine patrol bomber aircraft developed for the Imperial Japanese Navy in World War II. The Allied reporting name was Lorna. Although similar in appearance to the German Junkers Ju 88 medium bomber, the Q1W was a much smaller aircraft with significantly different design details.
The Douglas DT bomber was the Douglas Aircraft Company's first military contract, forging a link between the company and the United States Navy. Navy Contract No. 53305 of April 1, 1921, required only 18 pages to set out the specifications that resulted in the purchase of three DT folding-wing aircraft.
The Douglas DC-4E was an American experimental airliner that was developed before World War II. The DC-4E never entered production due to being superseded by an entirely new design, the Douglas DC-4/C-54, which proved very successful.
The Grumman XTSF was a proposed twin-engine torpedo scout aircraft, designed by Grumman for the United States Navy towards the end of World War II. Based on the design of the Grumman F7F Tigercat fighter, but enlarged and with the addition of a bomb bay, the XTSF was deemed too large for carrier operations, and the project was cancelled before any aircraft were built. Instead, the Navy chose to order the single-engine XTB3F, which became the successful AF Guardian.
The Mitsubishi Ki-51 was a light bomber/dive bomber in service with the Imperial Japanese Army during World War II. It first flew in mid-1939. Initially deployed against Chinese forces, it proved to be too slow to hold up against the fighter aircraft of the other Allied powers. However, it performed a useful ground-attack role in the China-Burma-India theater, notably from airfields too rough for many other aircraft. As the war drew to a close, the Japanese began using them in kamikaze attacks. Total production was around 2,385 units.
The Yokosuka B4Y was a carrier-borne torpedo bomber used by the Imperial Japanese Navy Air Service from 1936 to 1943. The B4Y replaced the Mitsubishi B2M2 and the Yokosuka B3Y, and was the last biplane bomber used operationally by the Imperial Japanese Navy. The Allied reporting name was "Jean". This aircraft was mistakenly identified by the British as the Nakajima Navy G-96.
The Nakajima G5N Shinzan was a four-engined long-range heavy bomber designed and built for the Imperial Japanese Navy prior to World War II. The Navy designation was "Experimental 13-Shi Attack Bomber"; the Allied code name was "Liz".
The Douglas T2D was an American twin-engined torpedo bomber contracted by the military, and required to be usable on wheels or floats, and operating from aircraft carriers. It was the first twin-engined aircraft to be operated from an aircraft carrier.
The Curtiss XBT2C was a prototype two-seat, single-engined dive/torpedo bomber developed during World War II for the United States Navy. Derived from the Curtiss SB2C Helldiver dive bomber, it was an unsuccessful competitor to meet a 1945 Navy specification for an aircraft to combine the roles that previously required separate types. Unlike the other competitors, the XBT2C was designed to accommodate a radar operator.
The Kaiser-Fleetwings XBTK was an American dive and torpedo bomber developed by Kaiser-Fleetwings for the United States Navy starting in 1944. After only five examples had been built, with the first two being flying prototypes; the contract was terminated in September 1946.
The Nakajima D3N was a Japanese carrier-based dive bomber of the 1930s. Three prototypes were built for the Imperial Japanese Navy, but no production followed, with the Aichi D3A being selected instead.
