Tiny Tim Missile

Collection Item Summary:

The Tiny Tim air-to-ground missile was the largest American rocket in service during World War II. It weighed 1,250 pounds (567 kg.) and was also designated the 11.75-inch aircraft rocket (its diameter or caliber). The TNT warhead weighed 148.5 lbs (67.3 kg.), which could destroy coastal defense guns, pill boxes, bridges, tanks, and ships. The missile was primarily used by a Marine Corps Air Group and was mounted on F4U aircraft.

Tiny Tims sunk at least one Japanese ship and seriously damaged another. During the Korean War, one Tiny Tim knocked out a key bridge. Visible in this partial cutaway are simulated solid-propellant sticks and the rocket's 24 exhaust nozzles. This object was donated to the Smithsonian by the U.S. Navy in 1964.
