Lockheed Martin Corp. received an $11m contract to develop and integrate a surface mine countermeasure system for the Navy's Avenger-class ships. Lockheed Martin will develop hardware, software and interfaces for the so-called Expendable Mine Neutralization System, or EMNS. The system, which will be integrated on the Navy's Mine Counter Measures Avenger-class ship, is designed to protect carriers and expeditionary strike forces by neutralizing mines located at the bottom of the sea or suspended in water.
