Shown here is a booster rocket for the JB-2 Loon submarine-launched guided missile. Built by Aeroject Engineering Corporation, the booster produced a thrust of 33,000 pounds for half a second. Unlike the standard booster, which used four separate solid-fuel JATOs that burned longer--for two seconds--this unit embodied the Navy's desire to adapt a "zero-length" launch capability to the Loon. The Navy conducted tests with this variant booster aboard the USS Cusk off the California coast in 1947-1948.

The Navy canceled the Loon program in 1950 in favor of the longer-range and more accurate Regulus I guided missile.

Transferred from the U.S. Navy.
