The Long Range Anti-Ship Missile (LRASM) is an anti-ship missile being developed by DARPA for the US Navy.[4]

Design[]

Unlike current anti-ship missiles the LRASM will be capable of conducting autonomous targeting, relying on on-board targeting systems to independently acquire the target without the presence of prior, precision intelligence, or supporting services like Global Positioning Satellite navigation and data-links. These capabilities will enable positive target identification, precision engagement of moving ships and establishing of initial target cueing in extremely hostile environment. The missile will be designed with advanced counter-countermeasures to effectively evade hostile active defense systems.[5]

The LRASM is based on the AGM-158B JASSM-ER, but incorporates a multi-mode radio frequency sensor, a new weapon datalink and altimeter, and an uprated power system. It has a reduced range than the JASSM-ER, similar to that of the original JASSM. It can be directed to attack enemy ships by its launch platform, receive updates via its datalink, or use onboard sensors to find its target. LRASM will fly towards its target at medium altitude then drop to low altitude for a sea skimming approach to counter anti-missile defenses.[2]

LRASM is designed to be compatible with the Mk 41 Vertical Launch System used on many US Navy ships[6] and to be fired from aircraft,[7] including the B-1 bomber.[8] For surface launches, LRASM will be fitted with a modified Mk 114 jettison-able rocket booster to give it enough power to reach altitude. Although priority development is on air and surface-launched variants, Lockheed is exploring the concept of a submarine-launched variant.[2]

History[]

The program was initiated in 2009 and started along two different tracks. LRASM-A is a subsonic cruise missile based on Lockheed Martin's 500 nm-range AGM-158 JASSM-ER - Lockheed Martin was awarded initial development contracts.[9] LRASM-B was planned to be a high-altitude supersonic missile along the lines of the Indo-Russian Brahmos, but it was cancelled in January 2012. 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".[10]

On October 1, 2012, Lockheed received a contract modification to perform risk reduction enhancements in advance of the upcoming flight test of the air-launched LRASM A version.[11] On March 5, 2013, Lockheed received a contract to begin conducting air and surface-launch tests of the LRASM. Three air-launched tests are scheduled for 2013, with one from a B-1 Lancer. Two surface-launch tests are scheduled for 2014. The contract includes risk reduction efforts, such as electromagnetic compatibility testing of the missile and follow-on captive carry sensor suite missions.[12]

On June 3, 2013, Lockheed successfully conducted "push through" tests of a simulated LRASM on the Mk 41 Vertical Launch System (VLS). Four tests verified the LRASM can break the canister's forward cover without damaging the missile.[13]

On July 11, 2013, Lockheed reported successful completion of captive-carry testing of the LRASM on a B-1 Lancer.[2]

On August 27, 2013, Lockheed conducted the first flight test of the LRASM, launched from a B-1.[14] Halfway to its target, the missile switched from following a pre-planned route to autonomous guidance. It autonomously detected its moving target, a 260 ft unmanned ship out of three in the target area, and hit it in the desired location with an inert warhead. The purpose of the test was to stress the sensor suite, which detected all the targets and only engaged the one it was told to. Two more flight tests are planned this year, involving different altitudes, ranges, and geometries in the target area. Two launches from vertical launch systems are planned for summer 2014.[15] The missile had a sensor designed by BAE Systems. The sensor is designed to enable targeted attacks within a group of enemy ships protected by sophisticated air defense systems. It autonomously located and targeted the moving surface ship. The sensor uses advanced electronic technologies to detect targets within a complex signal environment, and then calculates precise target locations for the missile control unit.[16]

On September 17, 2013, Lockheed launched an LRASM Boosted Test Vehicle (BTV) from a Mk 41 VLS canister. The company-funded test showed the LRASM, fitted with the Mk-114 rocket motor from the RUM-139 VL-ASROC, could ignite and penetrate the canister cover and perform a guided flight profile.[17]
