This vehicle is basically an M4A1Sherman tank composite hull HVSS with diesel engine (M-50) with the turret replaced.
The Kilshon is a tank fitted to launch the American Shrike anti radiation missile (and later Standart missiles) . The system was planned, produced and pressed into service right after the 1973 Yom Kippur War. It was meant to be used against Syrian and Egyptian SAM batteries radars, without endangering any planes and pilots. Taken out of service about the 1980s.
