Sopwith T. 1 The Cuckoo Story
Torpedo bombers arrived as a fleet of military aircraft before World War I (1914-1918), when advances in aviation made it possible to carry torpedo weapons. Before the Great Conflict, the British, Americans and Italians had all tried the concept in one form or another.
Once total war broke out, naval aviation began to use torpedo bombers on a regular basis, and aircraft were eventually designed specifically for this role.
With the war in full swing in October 1916, the British authorities turned to Sopwith Air, maker of the famous "Camel" biplane, to design and develop a new biplane bomber that would It can be launched from the deck of a moving ship along its belly carrying the torpedo. This is the "T. 1", a single-seat, single-engine biplane with traditional aircraft qualities, including an open-air cockpit, fixed-wheel landing gear and tail. To make up for the limited space on the carrier at the time, the T.1's wings were designed to fold back against the fuselage.
With no fishing gear installed, the T.1 can take off from the boat but cannot land on it. Instead, it's designed for water landings and can be recovered. Her war load was a 1 x 1,000 lb Mk. IX series torpedo, which was dropped under the hull.
Power is provided by a 200 hp Hispano-Suiza 8Ba engine located in the nose, driving a two-bladed wooden propeller.
The first flight of the T.1 prototype was recorded in June 1917, and tests were followed by formal evaluations that continued into the summer. Satisfied with what they had, the Royal Navy committed to buying 100 of these planes through an initial series order, but a shortage of the necessary engines meant the airframe was modified to accept the 200 hp Sunbeam "Arabian" engine.
Both Fairfield Engineering and Pegler and Company were used to provide the required manufacturing facilities - although neither had experience building fighter jets.
It seems that a lot of people are already against the promising T.1, known as "Kuckuck" at the time. To spur mass production, the Navy turned its attention to industry veteran Blackburn, a production-quality aircraft arriving in May 1918.
After some practical use of the type, some shortcomings were corrected, including a revised empennage and reinforced landing gear. By October 1918, both Fairfield and Pegler were able to participate in mass production and put their available talent into the effort to produce some 70 aircraft (50 and 20, respectively).
Despite the promises, the war ended with an armistice in November 1918, and the often delayed T.1 was no longer in great demand. 300 cuckoos were originally ordered, although only 232 were realized in total (less than 100 were available when Germany surrendered).
The active T.1 remained in service until its final retirement in 1923, and the line has never recorded combat use.
However, during its short service life, the T.1 was a fighter that was highly regarded by British pilots. The replacement Arabian engines did not work well, so 20 aircraft were modified to use 200 hp Wolseley "Viper" engines, these became the Cuckoo Mk II - making the original model the Mk. 1. At least one T.1 was equipped with a 275-horsepower Rolls-Royce Falcon III engine, but this form was not used in mass production.
Again, Sopwith B. 1 made it two prototypes and that was it.
Outside the Royal Naval Air Service, the Cuckoo is operated by RAF Squadrons 185, 186 and 210. The Imperial Japanese Naval Air Service took over the inventory of 6 Mk.
II Gestalt aircraft that were critical to the development of the Japanese Navy's carrier-based aircraft theory prior to World War II (1939-1945).
