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. [1]

Development and design

In 1925, the United States Navy's Bureau of Aeronautics designed a twin-engined torpedo bomber aircraft, intended to have greater performance than contemporary single-engined aircraft. [1] A single prototype was built by the Naval Aircraft Factory as the XTN-1, which was quickly followed by three identical aircraft built by Douglas, the T2D-1.

The XTN/T2D was a large two bay biplane, capable of easy conversion between floats and wheels, and carrying a crew of four.

Operational history

The first three T2D-1's were delivered to the torpedo bomber squadron VT-2 on 25 May 1927, [1] being used for successful trials aboard the aircraft carrier Langley. A further nine T2D-1's were ordered in 1927, these normally being operated as floatplanes, partly owing to criticism from the Army of the Navy operating large land-based bombers, [1] and partly as its large size prevented Langley from embarking a full airwing. [2]

A further 18 aircraft were ordered in June 1930 as patrol floatplanes, being designated P2D-1. These were operated by Patrol Squadron VP-3 in the Panama Canal Zone until they were replaced by Consolidated PBYs in 1937. [1]

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.

<span class="mw-page-title-main">Curtiss Model R</span> Type of aircraft

The Curtiss Model R was a utility aircraft produced for the United States Army and Navy during World War I. It was a conventional, two-bay biplane with slightly staggered wings of unequal span. The aircraft was provided with two open cockpits in tandem and fixed tailskid undercarriage, but many were built for the Navy with twin floats replacing the wheels. During the course of the war, Model Rs were used for general liaison and communication duties, as well for observation, training, and as air ambulances. In practice, the Curtiss powerplants supplied with these aircraft proved insufficient and were mostly replaced with Liberty engines. The Navy's Model R-3 floatplane had extended-span, three-bay wings, and was intended for use as a torpedo bomber. Some of these were later fitted with wheeled undercarriage and transferred to the Army as bombers under the designation Model R-9.
