Report on Navy Laser, Railgun and Gun-Launched Guided Projectiles
The following is the Oct. 15, 2020, Congressional Research Service report, Navy Lasers, Railgun, and Gun-Launched Guided Projectile: Background and Issues for Congress.
From the report
Three new ship-based weapons being developed by the Navy—solid state lasers (SSLs), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), also known as the hypervelocity projectile (HVP)—could substantially improve the ability of Navy surface ships to defend themselves against surface craft, unmanned aerial vehicles (UAVs), and eventually anti-ship cruise missiles (ASCMs).
