Northrop Grumman won a $24.9 million contract modification from the U.S. Navy for a second Low Rate Initial Production lot of three units for the Airborne Laser Mine Detection System (ALMDS). ALMDS is a Light Detection and Ranging Airborne Mine Countermeasures high area coverage system that detects, classifies and localizes floating and near-surface moored sea mines. The system is deployed from the MH-60S helicopter and will provide organic airborne mine defense to the battle force, the Navy said. Work will be performed in Melbourne, Fla., and work is expected to be completed by 2010.
