An anti-ship missile developed by DARPA for the US Navy. Unlike earlier versions of anti-ship missiles, the LRASM is capable of conducting autonomous targeting. Its on-board targeting systems is capable of independently acquiring enemy targets without the presence of prior, precision intelligence, or supporting services like Global Positioning Satellite navigation and data-links. Through positive target identification, precision engagement of moving ships, and establishing of initial target cueing, the missile uses what is called advanced counter-countermeasures to effectively evade active defense systems in extremely hostile environment.

The LRASM program was initiated in 2009 to create a subsonic cruise missile based on Lockheed Martin's 500 nm-range AGM-158 JASSM-ER. Captive carry flight tests of LRASM sensors began in May 2012; a missile prototype is planned to fly in early 2013 and the first canister launch is intended for end 2014.
