|Long Range Anti-Ship Missile|
“Unlike current anti-ship missiles LRASM 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. As an autonomous weapon LRASM will rely exclusively on on-board sensors and processing systems. According to DARPA, 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.…LRASM will comply with existing weapon launchers and storage systems, fitted to match existing the VL-41 Vertical Launch System carried on board all modern U.S. Navy combat ships.…Two LRASM concepts were assessed - LRASM B, a high altitude, supersonic, ramjet-powered cruise missile. This design leverages prior ramjet development activities and a suite of supporting sensors and avionics to achieve a with balanced speed and stealth for robust performance. The second LRASM design is stealthier, low-level cruise-missile designated LRASM A. This design utilizing the Joint Air to
(JASSM-ER) airframe, added with additional sensors and systems to achieve a stealthy and survivable subsonic cruise missile. LRASM A is considered more suitable for air launched applications.” Surface Standoff Missile Extended Range
“While LRASM is positioned as a direct successor for the Harpoon, the development of a more ambitious weapon known as ArcLight is also under evaluation at DARPA as a quick reaction weapon hitting time critical targets at a distance of 2,000 nautical miles within 30 minutes. ArcLight will employ a rocket booster, sustainer accelerating the weapon to hypersonic speed, from where the strike vehicle will glide at high speed, carrying a warhead weighing 100-200 pounds to strike the target with pinpoint accuracy. ArcLight, like LRASM, will also be stored in, and launched from existing Mk 41 VLS.”
Though late in coming, it appears that the Navy is finally begining to get serious about surface warfare. Now, if only they'll get serious about mine warfare, naval gunfire support for land forces, and anti-submarine warfare!
