Northrop Grumman designs and produces missile products including solid rocket motors and advanced high speed propulsion systems, fuzes, warheads, propellants and controls for air, sea and land-based systems. We are continually creating and reimagining products to meet or exceed today's program requirements and battlefield challenges, affordably.
Smart Bomb Fuzes and Proximity Sensors
For nearly half a century, Northrop Grumman and its heritage companies have been designing and developing bomb fuzes that have stayed on pace with the technological advancements of the time. Today our fuze technology is transitioning from legacy mechanical moving parts to all-electronic construction which has significantly improved munitions' functionality, as well as production and delivery.
FMU-167/B Hard Target Sensing Fuze
A marvel of sophisticated engineering, the FMU-167/B is powerful enough to drive a bomb through meters of concrete and rock while counting voids that are indicative of a deeply buried underground complex. By counting these voids, the “smart” fuze can detonate at a preprogrammed location within the structure, defeating adversaries' high-value assets
FMU-139 General-purpose Bomb Fuze
Building on the success of FMU-167/B, Northrop Grumman has redesigned the standard FMU-139 general-purpose bomb fuze to create the FMU-139 D/B. Its all-electronic design enables the fuze to handle longer missions, and function as both a general-purpose fuze and a penetrator fuze.
Precision Proximity Sensors
Precision detonation of weapons over a target not only increases warfighters' effectiveness but equally as important, it significantly reduces collateral damage. Northrop Grumman's DSU-33 D/B proximity sensor does just that. Used in conjunction with bomb fuzes and employed in aerial munitions utilizing general-purpose, blast-fragmentation warheads, the DSU-33 D/B proximity sensor detonates bombs at a fixed height above surface targets, maximizing the warhead's blast and fragmentation effects.
Lethality Enhanced Ordnance (LEO) Warheads
In 2008, the Department of Defense (DoD) released a requirement that by 2019 all cluster munitions containing submunitions not result in more than one percent unexploded ordnance after arming. In response to that requirement, Northrop Grumman developed LEO. This innovative warhead technology eliminates unexploded ordnance and contains no submunitions while providing equal or greater munition performance required by the warfighter. Greater performance is achieved when a traditional warhead is replaced with a LEO warhead of the same size and equal performance is achieved with a smaller warhead that then frees up space with the missile system for a larger rocket motor and thus extending the munitions' range. Our scalable solution has been successfully tested on warheads as small as 0.5 lbs and up to 250 lbs.
Tactical Propulsion Systems
Insensitive Munitions Rocket Motors
Building on our long history of designing and manufacturing high-performance propulsion systems for air-, sea- and land-based missiles, two game-changing Northrop Grumman technologies have emerged in recent years: affordable insensitive munitions (IM) rocket motors and air-breathing propulsion systems for hypersonic weapons. Northrop Grumman's affordable IM technology combines three simple technologies to create an advanced IM solution that makes our propulsion systems chemically stable enough to withstand mechanical shocks, fire and impact by shrapnel, and still function as intended to destroy their targets, providing uncompromising effectiveness and greater safety to our warfighters. Products include:
- AIM-9M Sidewinder Rocket Motor
- AIM-9P Sidewinder Rocket Motor
- AIM-9X Sidewinder Rocket Motor
- Chaparral M-121 Rocket Motor
- Evolved Sea Sparrow Missile-Propulsion System (ESSM)
- HELLFIRE® Rocket Motor
- IM GMLRS Rocket Motor
- IM Joint Air-to-ground Missile Rocket Motor (IM JAGM)
- Maverick Rocket Motor & Heavy Warhead
- RAM Block 1 Rocket Motor
- RAM Block 2 Rocket Motor
- Oriole Sounding Rocket Booster Motor
- STAR™ Space Propulsion and Stages
- Aerothermal Research and Test Facilities
- Ignition Safety Devices
Northrop Grumman's proven scramjet combustors will be a critical component in the next generation of tactical missile systems — air-breathing hypersonic weapons. Our scramjet engines use high vehicle speed to forcibly compress incoming air before combustion to enable sustained flight at hypersonic speeds. Such speeds reduce flight times and increase weapon survivability, effectiveness and flexibility.
