This is a cutaway model of the packaged liquid fuel LR-62 rocket motor for the U.S. Navy's Bullpup B surface-to-air missile. An improved and higher thrust variant of the LR-58 motor used in the Bullpup A (see the entry for A19770188000), the LR-62 produced 30,000 pounds of thrust for 2.3 seconds and had a storage life of five years. The Reaction Motors Division of the Thiokol Chemical Corporation began building the engine in the late 1950s, and it proved to be very successful as the powerplant for the widely used Bullpup B in Vietnam.

The LR-62 included storable, self-igniting propellants of mixed amine that proved ideal for the Bullpup's mission as an inexpensive and highly effective tactical weapon against a variety of ground targets, such as tanks, truck convoys, bridges, and railroad lines.
