The Tupolev Tu-98 (NATO reporting name Backfin) was a prototype swept wing jet bomber developed by Tupolev for the Soviet Union.
Design and development
The Tu-98 emerged from a program for a fast supersonic bomber to replace the Tupolev Tu-16. It was powered by two Lyulka AL-7 turbojet engines with side-mounted intakes high on the fuselage (above the wingroot). The Tu-98 was built in 1955 and first flown in 1956.[1] It was shown to an American delegation at the Tushino airfield outside Moscow in June 1956,[2] but it subsequently did not enter service, and only the single prototype was completed.[3]
The basic design of the Tu-98 had a great influence on the subsequent prototype of the Tupolev Tu-28 interceptor, officially known as the Tu-128 (NATO codename 'Fiddler').[4]
