For more than a decade the Navy has labored to develop a workable rail gun, a futuristic weapon that fires projectiles at up to seven times the speed of sound using electricity. It failed.
The Washington Post quotes Matthew Caris, a defense analyst at Avascent Group, a consulting firm saying “The railgun is, for the moment, dead.”
All told, the Navy spent about $500 million on research and development, according to Bryan Clark, an analyst at the Hudson Institute. Now, the Navy has cut funding for railgun research from its latest budget proposal. The Defense Department is turning its attention to hypersonic missiles to keep up with China and Russia.
