U.S. Military Tests Hypersonic Booster Motor

The U.S. Navy Strategic Systems Programs (SSP) successfully conducted a second test of the First Stage Solid Rocket Motor (SRM) on Thursday, in Promontory, Utah.

These tests are part of the Navy’s aim to develop Conventional Prompt Strike (CPS) offensive hypersonic strike capability and the Army’s Long Range Hypersonic Weapon (LRHW). The offensive weapon systems will enable precise and timely strike capability against deep inland targets in contested environments.

''Today’s successful test brings us one step closer to the design validation of our new hypersonic missile that will be fielded by both the Navy and the Army,'' said Vice Adm. Johnny R. Wolfe Jr, Director, Navy's Strategic Systems Programs, which is the lead designer for the common hypersonic missile. ''We are on schedule for the upcoming flight test of the full common hypersonic missile.”

This SRM test is part of a series of tests validating the newly developed common hypersonic missile. This live fire test follows previous tests of the First and Second Stages on May 27 and August 25, 2021. This static fire test marked the first time the First Stage SRM included a thrust vector control system. The thrust vector control system is a key component of the missile booster that allows the rocket motors to be maneuverable in flight, the Navy said in a release today.

U.S. peer competitors are weaponizing and fielding hypersonic capabilities, creating warfighting asymmetry that must be addressed. These tests are vital in developing a Navy-designed common hypersonic missile that the Navy and Army will field. The common hypersonic missile will consist of the first stage SRM as part of a new missile booster combined with the Common Hypersonic Glide Body (CHGB).

The Navy and Army are on track to test the full common hypersonic missile that will be a catalyst for fielding the CPS and LRHW weapon systems. The services are working closely with government national laboratories and industry to continue developing and producing the common missile.

Information gathered from ongoing tests will further inform the services offensive hypersonic technology development. Hypersonic weapons are capable of flying at speeds greater than five times the speed of sound (Mach 5), are highly maneuverable and operate at varying altitudes. The common hypersonic missile design for sea and land-based applications provides economies of scale for future production and relies upon a growing U.S. hypersonics industrial base.
