This is a rocket grapnel, Mark 1 Model 0, and adapters, for use with World War II vintage U.S. Navy rockets. It uses a 3.25-inch rocket motor. The grapnel was developed by the American inventor Wadsworth W. Mount for the purpose of throwing life lines for rescue work at sea, or from ship to shore as life saving rockets and used standard U.S. Navy rockets.
Successful tests of these rockets were conducted from 1944 to 1946. However, they were not adopted by the Coast Guard or other services, although they were allegedly adapted for testing soil samples during post-war Atomic bomb tests. The grapnel was donated to the Smithsonian by Mount in 1976.
