General Atomics Electromagnetic Systems said that it demonstrated its Blitzer railgun during a three-week U.S. Army exercise in April at Fort Sill, Okla.

Electromagnetic railguns can send projectiles at speeds several times the speed of sound. Exercise participants at Fort Sill fired the railgun 11 times.

Part of the exercise was to show how the railgun can be efficiently broken down at one site, transported under real-world conditions and reassembled at another site, GA said.

La Jolla-based General Atomics did not get the main contract for the U.S. Navy’s railgun — though it is a subcontractor. In 2013, a GA executive said the business wanted to get railgun work from the Army and U.S. Marine Corps.
