Beautiful Pics Of A Rare Tu-128 – The Largest & Heaviest Fighter Ever In Service


 


The Tupolev Tu-28 (NATO reporting name Fiddler) was a long-range interceptor aircraft introduced by the Soviet Union in the 1960s.  It was the largest and heaviest fighter ever in service.
In the 1950s, the Soviet Union sought the means to defend against the nuclear-armed American bombers possibly penetrating its borders. Contemporary interceptors were able to cover a radius of a few hundred kilometers; the newly developed surface-to-air missiles had even shorter range. Considering both, the sheer numbers required to defend a 5,000 km air front were economically impossible to maintain.
This left the Soviet Union able to provide a modern air defense only for selected valuable areas. The PVO decided to cover the entire territory, but with a more loose defense. In 1955 it placed a requirement for a large area-defense interceptor, that would achieve it with sparse airbases.
The work began in 1958, based on an existing single prototype of the unsuccessful Tu-98 supersonic bomber. The military designation of the interceptor was at first Tu-28, but it had been changed in 1963 to Tu-128.
The Tu-128’s only publicly reported combat operation was the destruction of NATO reconnaissance balloons. The aircraft remained in service until 1990. Through the 1980s, units armed with the Tu-128 converted to the Mikoyan MiG-31.

Development of various projects designated Tu-28A, Tu-28-80, Tu-28-100, Tu-138, and Tu-148 were proposed by the Tupolev Design Bureau but all were abandoned.
