San Diego’s General Atomics Reveals Railgun Technology, Developed Through Internal R&D

destroy its target, leading some to describe the system as a kinetic weapon.

A GA spokeswoman says Blitzer works on the same principles as the Navy’s railgun, but GA developed its design for Naval warship self-defense on internal research and development funds. The company used a similar “build on spec” approach during the early 1990s to develop the highly successful Predator family of unmanned aircraft.

In its statement today, GA says the railgun projectiles, which are technically known as sabots, were repeatedly launched by the Blitzer system with acceleration levels exceeding 60,000 g. The sabot packages separated as designed and the sabots flew stable trajectories.

A railgun consists of two parallel rails that are highly conductive. One rail carries a positive electric current, the other a negative current. The sabot is mounted on a conductive device that bridges the two rails, completing the electric circuit. This allows the current to flow, which creates a magnetic field and a force that propels the sabot at tremendous velocity.

GA says its Blitzer technology offers a leap-ahead, multi-mission capability for both naval and land-based military use. A single system could provide a defensive capability against a number of advanced naval threats from both aircraft and surface vessels. It also could provide a standoff strike capability against land- and sea-based targets, with the promise of increased range at a muzzle velocity that’s more than twice that of conventional gun systems.

In a statement released by the company, GA Advanced Weapon Launcher Systems Director Tom Hurn says, “The tested systems performed flawlessly, and were consistent with performance expectations.”

In Memoriam: Our dear friend Bruce V. Bigelow passed away on June 29, 2018. He was the editor of Xconomy San Diego from 2008 to 2018. Read more about his life and work here. Bruce Bigelow joined Xconomy from the business desk of the San Diego Union-Tribune. He was a member of the team of reporters who were awarded the 2006 Pulitzer Prize in National Reporting for uncovering bribes paid to San Diego Republican Rep. Randy “Duke” Cunningham in exchange for special legislation earmarks. He also shared a 2006 award for enterprise reporting from the Society of Business Editors and Writers for “In Harm’s Way,” an article about the extraordinary casualty rate among employees working in Iraq for San Diego’s Titan Corp. He has written extensively about the 2002 corporate accounting scandal at software goliath Peregrine Systems. He also was a Gerald Loeb Award finalist and National Headline Award winner for “The Toymaker,” a 14-part chronicle of a San Diego start-up company. He takes special satisfaction, though, that the series was included in the library for nonfiction narrative journalism at the Nieman Foundation for Journalism at Harvard University. Bigelow graduated from U.C. Berkeley in 1977 with a degree in English Literature and from the Columbia University Graduate School of Journalism in 1979. Before joining the Union-Tribune in 1990, he worked for the Associated Press in Los Angeles and The Kansas City Times.
