U.S. AIR FORCE
(Defenselink -- December 16, 2003) Alliant Precision Fuze Co., Janesville, Wis., is being awarded a
$9,999,886 firm fixed price contract modification to provide for DSU-33B/B proximity
sensor, a nose-mounted radio frequency proximity sensor used on M117 and MK-80 series general-purposed and the Joint Direct Attack Munition. The DSU-33B/B
provides a sensor fire pulse, which in turn initiates bomb detonation at a height-of-burst (HOB) nominally 20 feet. The HOB detonation capability enhances the
performance of general-purpose bombs and JDAMs for above ground targets. The DSU-33B/B can provide a fire pulse to the following fuzes: FMU-139, FMU-139 A/B,
FMU-139B/B, and the FMU-152/B. Power for the DSU-33B/B is provided by an internal
battery, which is initiated by either an FZU-48/B or the FZU-55/B and FZU-55A/B in
the Air Force configuration, or the Fuze Function Control Set in the Navy configuration. The sensor is qualified for use on the following aircraft and each
variant in their series: Marines AV-8, Navy/Marine F/A 18, and Air Force A-10, F-15, F-22, B-52, B-1 and B-2 including foreign military sales versions. This
action is for the Exercise of option 3 for the procurement of 4,922 DSU-33B/B proximity sensors and cables under this option. This action also includes the
procurement of an additional 2,768 DSU-33B/B proximity sensors and cables under option 2. Total funds have been obligated. This work will be complete by August
2005. The Air Armament Center, Eglin Air Force Base, Fla., is the contracting activity (F08635-02-C-0049, P00009).
