The Light Airborne Multi-Purpose System (LAMPS) is the United States Navy's program that develops crewed helicopters to assist the surface fleet in anti-submarine warfare. The purpose of LAMPS is to scout outside the limits of a fleet's radar and sonar range to detect and track enemy submarines or missile-equipped escort ships and feed the real-time data back to their LAMPS mothership. They also have the capability to directly engage enemy targets with depth charges or torpedoes, or indirectly engage the enemy by coordinating fleet assets on site.
