Overall: 2ft 7 1/2in. x 4ft 2in. x 5in., 180lb. (80.01 x 127 x 12.7cm, 81.6kg)
Other (Ramjet): 5ft 1in. x 8in., 50lb. (154.94 x 20.32cm, 22.7kg)
Boosters, steel bodies, aluminum fins; steel framework to top and bottom; individual nozzles, steel, but brass colored, with length of tan colored plastic insulated electrical igniter wire. Ramjet, major portion of cylinder, wood, with wooden protective disc inserted at base; steel air intake cowling, about 10 inches long from top, and steel projecting air intake cone.
This is a replica of the Bumblebee ramjet-powered missile. The booster was made of a cluster of four standard solid-fuel 5-inch caliber HVAR (High Velocity Aircraft) rockets with fins attached. The booster shown here uses real HVAR rocket bodies although they do not contain propellants.
Bumblebee was a U.S. Navy research program for the development of a ramjet or rocket-powered surface-to-air guided missile to combat Kamikaze (Japanese suicide) planes threatening U.S. shipping during World War II.The first successful flight was conducted on 13 June 1945. This replica is of one of several small scale Bumblebee vehicles tested. Project Bumblebee eventually evolved into the Talos ship-to-air missile.
This object was donated to the Smithsonian in 1951 by the Johns Hopkins University.
