General Atomics Electromagnetic Systems (GA-EMS) has completed successful open-range testing of the railgun projectile guidance electronics unit (GEU) at the US Army Dugway Proving Ground in Utah.
During the testing, five test projectiles were fired from GA-EMS' 3 mega joule Blitzer electromagnetic railgun system at accelerations greater than 30,000 times that of gravity.
The projectiles and their critical components were able to operate in the launcher's multi-Tesla magnetic field and the overall launch environment.
All of the GEU components performed as expected during and after launch, and through a period of aero-stable flight.
GA-EMS Missile Defense and Space Systems vice-president Nick Bucci said: "This latest testing series completes the risk reduction and technology maturation of the individual components of our electromagnetic railgun launched hypersonic projectiles.
"We continue to fire and test our projectiles in an open range setting, allowing us to collect and analyse a significant amount of performance data under real-world conditions."
The test projectiles included integrated navigation sensors and processors for guidance, navigation and control.
Since last year, the company has been working towards developing electromagnetic railgun-launched hypersonic projectiles and projectile components.
