- Tupolev Tu-98
The
Tupolev Tu-98 (NATO reporting name 'Backfin') was a prototypeswept wing jetbomber developed for theSoviet Union .Development
The Tu-98 emerged from a program for a fast
supersonic bomber to replace theTupolev Tu-16 . It was powered by twoLyulka 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. It was shown to an American delegation at the Kubinka air base outsideMoscow in June 1956, but it subsequently did not enter service, and only the single prototype was completed.The West incorrectly believed that the aircraft (thought to be an
Ilyushin orYakovlev design) was in service, possibly designated Yak-42, but that was not correct. The basic design of the Tu-98 did, however, have a great influence on the subsequent Tu-102, which became the basis of theTupolev Tu-28P 'Fiddler' interceptor.pecifications (Tu-98)
