Navy begins test of railgun launcher prototype at Dahlgren.

 Engineers at NSWC Dahlgren Division are in the midst of a monthlong series of tests of the railgun prototype.

Ellis said the Navy received about $240 million in funding for the initial phase of the project, and about the same amount would carry the work through 2017.

A video of one of six recent test shots from the BAE Systems launcher shows a technician loading an aluminum test slug in the launcher. That is followed by a bright flash of light at the muzzle, with the projectile emerging in a plume of fire as it exits the chamber and punches through a nearby target.

Tests began at a level of 20 megajoules; the power will eventually be ramped up to 32--the level at which the gun would operate under real-world conditions.

BAE Systems, a national defense contractor with an office in Stafford County, was awarded a $21 million contract last year to develop the launcher prototype.

The first test shot was in 2006 at Dahlgren, followed by a 10.6-megajoule shot in 2008, and the record shot in 2010.

NSWC Dahlgren Division is the largest tenant command of the Naval Support Facility Dahlgren.

According to the Navy, the railgun concept was born in 1864 when James Clark Maxwell developed electromagnetic field theory.

In the waning days of World War II, an elementary version was built, followed in 1946 by Westinghouse's "Electropult" aircraft launcher.

A 2008 test shot of a prototype at Dahlgren set a world record of 10 megajoules. That was eclipsed by a 32 megajoule shot in December 2010.
