The Tupolev Tu-91 (NATO reporting name Boot) was a Soviet naval attack aircraft. It was only built in prototype form, and cancelled after Joseph Stalin's death.

Development and design[edit]

Following the end of World War II, Stalin ordered an aggressive naval expansion to counter the US naval superiority. It called for building extra warships and a fleet of aircraft carriers. In order to equip the proposed carriers, Soviet Naval Aviation required a long-range carrier-based strike aircraft, capable of attacking with bombs or torpedoes. The Tupolev Design bureau decided on a single-engined turboprop aircraft, designated Tu-91 to meet this requirement.[1]

The Tu-91 was a low-winged monoplane with upswept wings. It was powered by an Isotov TV2 engine mounted mid-fuselage and driving a six-bladed Contra-rotating propeller in the nose via a long shaft. The crew of two sat side by side in a cockpit in the aircraft's nose, protected by armour plating. It could carry a heavy load of torpedoes or bombs on pylons under the fuselage and under the wings, and had a gun armament of two cannon in the wing roots and two more in a remotely controlled tail turret.[1]

After the death of Stalin in 1953, the planned fleet of carriers was cancelled, but development of the Tu-91 continued as a land-based aircraft, the design being revised to eliminate wing-folding and arresting gear. It first flew on 17 May 1955,[1] demonstrating excellent performance, resulting in production being authorized. However, after the aircraft was ridiculed by Nikita Khrushchev when inspecting the prototype, the Tu-91 was cancelled.[2]
