US army successfully tests laser defence system for forward bases

The US army has successfully tested a vehicle-mounted laser that managed to shoot down incoming mortar rounds and small drone aircraft, officials said.

Installed in a dome-shaped turret on a military vehicle, the high-energy laser hit more than 90 mortar bombs and several small unmanned planes over a six-week test at White Sands Missile Range in the US state of New Mexico.

The experimental weapon, dubbed the high energy laser mobile demonstrator (Helmd), was unlikely to be operational until 2022 if the army decided to purchase the system, officials said.

The system, armed with between three and five lasers, is designed to protect remote forward military bases from mortar, artillery or rocket attack. Such attacks were frequent against "forward operating" bases in Iraq and Afghanistan over the past decade.

The laser used in the test this month had a strength of 10 kilowatts (kW), but the programme would next use more powerful lasers of 50kW and then 100kW, officials said.

"If you are engaging a target at the same range, a 100kW laser will destroy the target in one-tenth of the time the 10kW would," said Terry Bauer, a programme manager at Boeing, which is the lead contractor involved in the Helmd project.
