The Martin A-22 Maryland (French designation Martin 167) is an American twin-engine bomber and reconnaissance medium wing aircraft, with a classic tail and a metal structure from the Second World War. The prototype flight took place in 1938. The plane was originally built to participate in the tender for a new USAAC attack reconnaissance aircraft, but despite its good performance, the plane did not meet with the interest of American decision makers. However, a lot of interest was expressed by the French air force, which in January 1939 placed an order for a batch of these aircraft. However, the engines (to the Wright R-1820 Cyclone 9 with 950KM each) and the weapons consisting of Belgian 7.5mm machine guns were changed. Deliveries began in November 1939 under the designation Martin 167A-3. After the defeat of France, Great Britain expressed interest in the machines built on its behalf. Engines were changed to Pratt-Whitney R-1830SC3-G Twin Wasp, 1050KM each, and entered the RAF under the designation Martin Maryland Mk.I. In 1941, the Mk.II version was created with more powerful engines and changed on-board weapons. In total, less than 500 copies of this machine were created. Martin Maryland fought in the French Campaign as well as in North Africa, Sicily and Italy in the service of the RAF. Technical data (Maryland Mk.I version): length: 14.2 m, wingspan: 18.7 m, height: 5 m, maximum speed: 489 km / h, maximum range: 2100 km, maximum ceiling 8990 m, armament: fixed - 5 machine guns cal 7.7 mm, suspended - up to 908 kg of bombs.
