Industry Snapshot

In 2001 U.S. manufacturers of propulsion units, engines, and propulsion unit parts for guided missiles and space vehicles recorded $1.5 billion in net sales. Nearly 26 percent ($382 million) of this total was attributable to military markets, while civilian applications accounted for the remaining $1.1 billion. The end-of-year backlog was $6.4 billion; $795 million for the military and $5.6 billion for nonmilitary.

In the 1990s there were two basic types of propulsion systems used for guided missiles and space vehicles—solid-fueled and liquid-fueled engines. Solidfueled engines were more commonly used because liquid fuels require storage at very low temperatures. Other rockets produced by this industry included hybrid rockets, which use a combination of solid and liquid fuel systems, small propellant rockets for adjusting the altitude of space vehicles, and rockets for track-borne research sheds. By the end of the century the industry was seeking a method to propel vehicles for longer and further space exploration. Nuclear fission, sun laser/solar sails, and anti-matter were just a few methods being researched by the early 2000s.
