US Navy preps hypersonic weapon test this spring

The U.S. Navy is heading into a major test of a hypersonic weapon that will help determine the way ahead for a joint development program with the U.S. Army, according to the Army’s Rapid Capabilities and Critical Technologies Office director.

“The Navy is moving forward on their test, which isn’t a launch out of ground support equipment, but just off a stool launch, so we get another look at the missile,” Lt. Gen. Robert Rasch told Defense News in a March 27 interview here at the Association of the U.S. Army’s Global Force Symposium.

The Navy’s test of the Common-Hypersonic Glide Body will lead into an Army test of the missile in the summer from a ground-based launcher, he said. “Right now, if things go as planned, we’ll be out at the range this summer.”

Hypersonic weapons are capable of flying faster than Mach 5 — or more than 3,836 miles per hour — and can manoeuvre between varying altitudes, making them difficult to detect. The C-HGB is made up of the weapon’s warhead, guidance system, cabling and thermal protection shield.

The U.S. is in a race to field the capability as well as develop systems to defend against hypersonic missiles. China and Russia are actively developing and testing hypersonic weapons.

The test in the spring is focused solely on missile performance and is conducted using a test stand that eliminates ground support equipment, canister and launcher.

The Army, at the same time, is ensuring that the ground support equipment for its Long-Range Hypersonic Weapon, or LRHW, works correctly and will then marry up the missile and launcher in the later test, Rasch explained.

The Army has spent several years working with Leidos’ Dynetics to build the industrial base for the hypersonic weapon glide body that will be used by both the ground service and the Navy because the domestic private sector had never built a hypersonic weapon.
