Sukhoi Su-15

The Sukhoi Su-15 is a twinjet supersonic interceptor aircraft developed by the Soviet Union.

It entered service in 1965 and remained one of the front-line designs into the 1990s.

The Su-15 was designed to replace the Sukhoi Su-11 and Sukhoi Su-9, which were becoming obsolete as NATO introduced newer and more capable strategic bombers.
