A great combat simulation video demonstrating the capability of the US Military Long Range Anti Ship Missile against Russian navy ships. The Long Range Anti-Ship Missile (LRASM) is a stealthy anti-ship cruise missile under development for the US Navy by the Defense Advanced Research Projects Agency (DARPA). The LRASM is intended as a replacement for the US Navy's current anti-ship missile, the Harpoon, which has been in service since 1977. Various launch platform configurations are being evaluated. LRASM is anticipated to pioneer autonomous targeting capabilities for anti-ship missiles.
The Navy was authorized by the Pentagon to put the LRASM into limited production as an operational weapon in February 2014 as an urgent capability stop-gap solution to address range and survivability problems with the Harpoon anti-ship missile and to prioritize defeating enemy warships, which has been neglected since the end of the Cold War but taken on importance with the modernization of the Chinese People’s Liberation Army Navy. The Navy will hold a competition for the Offensive Anti-Surface Warfare (OASuW)/Increment 2 anti-ship missile as a follow-on to LRASM to enter service in 2024.
Competitors to Lockheed Martin had protested the decision to award them a contract for 90 LRASMs given the circumstances of selection and competition for the missile. Raytheon claimed their JSOW-ER had comparable capabilities with lower costs. The Navy responded by saying Lockheed's LRASM program was limited in scope, the decision to move ahead with them was made after an initial DARPA contract award, and that it was an urgent need to face future threats. The OASuW Increment 2 competition will be completely open and start by FY 2017. It is expected the LRASM will compete against the joint Kongsberg/Raytheon offering of the Joint Strike Missile (JSM) for air-launch needs and an upgraded Raytheon Tomahawk cruise missile for surface-launch needs.

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.
The LRASM is based on the AGM-158B JASSM-ER, but incorporates a multi-mode radio frequency sensor, a new weapon data-link and altimeter, and an uprated power system. 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. DARPA states its range is greater than 200 nmi (370 km; 230 mi). Although the LRASM is based on the JASSM-ER, which has a range of 500 nmi (930 km; 580 mi), the addition of the sensor and other features will somewhat decrease that range.
To ensure survivability to and effectiveness against a target, the LRASM is equipped with a BAE Systems-designed seeker and guidance system, integrating jam-resistant GPS/INS, passive RF and threat warning receiver, an imaging infrared (IIR infrared homing) seeker with automatic scene/target matching recognition, a data-link, and passive Electronic Support Measure (ESM) and radar warning receiver sensors. Artificial intelligence software combines these features to locate enemy ships and avoid neutral shipping in crowded areas. Automatic dissemination of emissions data is classified, located, and identified for path of attack; the data-link allows other assets to feed the missile a real-time electronic picture of the enemy battlespace. Multiple missiles can work together to share data to coordinate an attack in a swarm. Aside from short, low-power data-link transmissions,the LRASM does not emit signals, which combined with the stealthy JASSM airframe and low IR signature reduces detectability. Unlike previous radar-only seeker-equipped missiles that went on to hit other vessels if diverted or decoyed, the multi-mode seeker ensures the correct target is hit in a specific area of the ship.
