Northrop SM-62 Snark

Although unofficially designated a surface-to-surface ICM, the Snark was essentially a small, turbojet-powered, unmanned aircraft. It was designed to be fired from a short mobile launcher by two solid-fueled rocket boosters. Once airborne, the Snark was powered by a single Pratt and Whitney J-57 turbojet engine capable of cruising at Mach .9 to an altitude of approximately 50,000 feet.    

After a programmed flight of 1,500 to 5,500 nautical miles, the Snark’s airframe separated from its nose cone, and the missile’s nuclear warhead followed a ballistic trajectory to its target. Plans developed by the Strategic Air Command employed the Snarks against enemy defensive systems, especially radars, to ensure the effective penetration of enemy territory by manned bombers.
