U.S. joint armed forces conducted a multi-platform live-fire missile exercise, Sept. 19, involving surface, air, and subsurface launched ordinance to sink the decommissioned frigate USS Curts (FFG 38) as part of exercise Valiant Shield 2020, the U.S. Navy announced.
The sinking exercise (SINKEX) combined an orchestrated sequence of live ordnance targeting the ex-USS Curts, including air-launched ordnance from fixed and rotary wing squadrons of Carrier Air Wing (CVW) 5, embarked aboard USS Ronald Reagan (CVN 76), surface-launched missiles from cruisers USS Antietam (CG 54) and Shiloh (CG 67), a subsurface launched missile from Los Angeles-class fast-attack submarine USS Chicago (SSN 721), as well as various supporting Navy and U.S. Air Force aircraft.
Air Force assets included tanker support from KC-135s and KC-10s of the 909th Air Refueling Squadron and 9th ARS, respectively.
Valiant Shield is a U.S. only, biennial field training exercise (FTX) with a focus on the integration of joint training in a blue-water environment among U.S. forces. This training enables real-world proficiency in sustaining joint forces through detecting, locating, tracking and engaging units at sea, in the air, on land, and in cyberspace in response to a range of mission areas.
