head System (MWS) with a 500 pound unitary warhead, providing blast/fragmentation effects as well as enhanced penetration capability against hard targets. The BROACH concept combines two forward shaped charges as part of the penetrator with a secondary follow-through bomb, supported by multi-event hard-target fuzing. The outcome is a warhead and fuze combination that provides more than twice the penetration achievable for equivalent single penetrating warhead types, at an equivalent weight and velocity. The warhead technology can be scaled and configured for a variety of weapon payload and targets requirements.

  • The Tactical Missile System Penetrator (TACMS-P) is an Advanced Concept Technology Demonstration (ACTD) program to demonstrate integration of the Army Tactical Missile System (ATACMS) booster with a Navy reentry body, resulting in an improved capability against buried and/or hardened targets. The TACMS-P range extends to 220 kilometers and will be compatible with the Multiple Launch Rocket System family of launchers. The reentry body has maneuvering capabilities for increased accuracy.

  • The Joint Air-to-Surface Standoff Missile (JASSM) is a conventionally armed, low-observable cruise missile. The missile has automatic target recognition, autonomous guidance, precision accuracy, and a 1,000 pound warhead optimized for penetration; it carries a new, high-yield explosive and a hard-target smart fuze.

  • The Joint Direct Attack Munition (JDAM) GBU-31/32, a guidance tail kit under development to meet both U.S. Air Force and Navy needs, converts existing unguided free-fall bombs into accurate, “smart munitions” for use in adverse weather. With the addition of a new tail section that contains an inertial navigational system and GPS guidance control unit, JDAM improves the accuracy of unguided, general-purpose bombs in any weather condition. The program will produce a weapon with high accuracy and an all-weather, autonomous, conventional bombing capability. JDAM will upgrade the existing inventory of general-purpose and penetrator unitary bombs, and a product improvement may add a terminal seeker to improve accuracy. JDAM can be launched from approximately 25 kilometers from the target, and each is independently targeted.

  • The Tactical Tomahawk Penetrator is a variation of the BGM-109 Tomahawk, which is an all-weather submarine or ship-launched land-attack cruise missile. After launch, a solid propellant propels the missile until a small turbofan engine takes over for the cruise portion of flight. Tomahawk is a highly survivable weapon. Its detection by radar is difficult because of the missile’s small-cross-section, low-altitude flight. Similarly, infrared detection is difficult because the turbofan engine emits little heat. Systems include a GPS receiver; an upgrade of the optical Digital Scene Matching Area Correlation (DSMAC) system; Time of Arrival (TOA) control, and improved 402 turbo engines. A modification of the Navy’s tactical Tomahawk missile is being developed that includes a penetrator warhead and the hard-target smart fuze.
