Army preps for key tests of seeker capable of attacking maritime targets January 20 Lockheed Martin's PrSM missile was tested for a third time at White Sands Missile Range, in New Mexico, on April 30, 2020. (Lockheed Martin) WASHINGTON — The Army is preparing for key tests of a multimode seeker for munitions that will be capable of attacking maritime targets, but current funding will prevent a faster timeline to integrate it into the Army’s future long-range missile, according to Brig. Gen. John Rafferty, who is in charge of the service’s long-range precision fires modernization efforts. The Precision Strike Munition (PrSM) is on track for initial fielding in 2023, but the in-development multimode seeker, known as the Land-Based Anti-Ship Missile (LBASM), will be integrated into the capability at a later date.
