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-7turbojet engines with side-mounted intakes high on the fuselage (above the wingroot). The Tu-98 was built in 1955 and first flown in 1956. It was shown to an American delegation at the Tushino airfield outside Moscow in June 1956, but it subsequently did not enter service, and only the single prototype was completed.
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').
