Northrop Grumman delivers 200,000th DSU-33 sensor which provides air-burst detonation

U.S. defense contractor Northrop Grumman has announced the delivery of its 200,000th DSU-33 Proximity Sensor, a technology which provides air-burst detonation of general purpose bombs for United States and allied airmen who rely on it as a force multiplier in combat.

According to a news release, iInitial production of the DSU-33B/B configuration began in 2000 and the product has evolved to the present DSU-33D/B configuration. Throughout its 18-year production history, an integrated product team, including representatives from government and industry, has ensured the sensor has remained effective for U.S. and allied warfighters’ needs today and well into the future.

DSU-33 Proximity Sensors have been used by the U.S. Air Force, U.S. Navy and Marine Corps, and multiple allied nations. They are currently being procured by the U.S. Army on behalf of the U.S. Air Force and foreign military users.


“The DSU-33 program illustrates collaboration and success in fielding what is truly a joint product,” said Pat Nolan, vice president, missile products, Northrop Grumman. “This level of teamwork exemplifies how we can significantly improve quality, reliability and capability, while simultaneously reducing the warfighter cost throughout the life of the program.”

Recently, members of the integrated program team including leadership from the U.S. Army’s Joint Program Executive Office for Armaments and Ammunition and the U.S. Air Force Materiel Command, visited Northrop Grumman’s Allegany Ballistics Laboratory to celebrate the milestone with past and present employees working on the program.

The DSU-33 Proximity Sensor is an all-weather, battery operated, active, radio frequency, ranging radar. Itis a single-mission device capable of operating in an electronic countermeasure environment. The sensor mounts on and provides a proximity function for the MK 80 and M117 series general purpose bombs.

The sensor is capable of both high- and low-drag releases and meets the unique requirements of the U.S. AirForce and Navy. For the Air Force and Navy, bombs are equipped with a FMU-139/B or FMU-152/B Bomb Fuze, a FZU-48/B or FZU-55/B Bomb Initiator, and a filtered power cable assembly.

Mix-and-match combinations of fuze, sensor, and initiator provide a lower cost alternative to fuze/sensor inone hardware package. The DSU-33 has passed the appropriate environmental tests of MIL-STD-331 and MIL-STD-801.D-801.
