Kh-90
Russian hypersonic cruise missile
From Wikipedia, the free encyclopedia
The Kh-90 GELA (Russian: ГЭЛА (гиперзвуковой экспериментальный летательный аппарат), Hypersonic Experimental Flight Vehicle) is a Soviet/Russian air-to-surface hypersonic missile. It was supposed to replace subsonic intermediate range missiles in the Soviet inventory. The missile was an ambitious project, as the main objective was to develop it into a hypersonic missile. It was to be a successor to the Kh-45, which never entered service.

The missile was designed by Raduga. It was equipped with a one-megaton thermonuclear warhead and used inertial navigation with mid-course update via data link. It had a maximum range of 3,000 km.
It was developed at the beginning of 1980, following the Kh-80 and Kholod projects.[4][5][6] It was shown to the public an MAKS Airshow 1995.[1]
