US Navy hypersonic missile engine successfully completes live fire ground test

The US Navy, in conjunction with the US Army, has successfully conducted a static fire test of the First Stage Solid Rocket Motor (SRM) which will be used in offensive weapon systems that will allow precise and rapid strike capability. against targets deep inland. in contested environments.

The live fire ground test at Promontory, Utah, marked the first time that the SRM first stage included a thrust vector control system. The thrust vector control system is a key component of the missile thruster that allows rocket engines to be maneuverable in flight.

The United States and its global rivals have stepped up efforts to build hypersonic weapons – the next generation of weapons that rob adversaries of reaction time and traditional defeat mechanisms. Defense contractors hope to capitalize as they manufacture weapons and develop new detection and neutralization mechanisms.

As part of this effort, the Navy Strategic Systems Programs (SSP) are working on a common hypersonic missile that will be used to develop the Conventional Prompt Strike (CPS) hypersonic offensive weapon for the US Navy and the hypersonic weapon long range (LRHW) for the US military.

These tests are critical to the development of a common Navy-designed hypersonic missile that the Navy and Army will deploy. Fired from a mobile launcher tube, the common hypersonic missile will include the SRM first stage as part of a new missile thruster combined with the Common Hypersonic Glide Body (CHGB).

The Navy and Army are on track to test the complete common hypersonic missile that will serve as a catalyst for commissioning the CPS and LRHW weapon systems. The services work closely with national government laboratories and industry to continue to develop and manufacture the common missile.

The information gathered from the ongoing tests will then be used to develop the technology to a practical level for the ground-to-ground LRHW for the military and the Navy’s CPS missile for ships and submarines, both of which share a design. common. Hypersonic weapons are capable of flying at speeds greater than five times the speed of sound (Mach 5), are very maneuverable, and operate at different altitudes. The common design of hypersonic missiles for maritime and land applications will provide economies of scale for future production and is based on a growing hypersonic industrial base in the United States.

“This test continues to build momentum to provide hypersonic capability to our fighters in support of the national defense strategy,” said LTG L. Neil Thurgood, director of hypersonics, directed energy, space and rapid acquisition. “The use of hypersonic weapons is one of the highest priority areas of modernization that the Department of Defense is pursuing to ensure our continued dominance on the battlefield, and the joint team has done a tremendous job in executing this. testing and keeping us on schedule. “
