US Navy MH-60S Patch — The Fleet's Do-Everything Helicopter Vertical replenishment at dawn, combat search and rescue at noon, mine countermeasures by sunset — the Sierra does it all. The MH-60S Seahawk — unofficially and universally known as the "Knighthawk" — is the U.S. Navy's multi-mission workhorse helicopter, designed to replace the aging CH-46 Sea Knight and consolidate an extraordinary range of missions into a single adaptable airframe. Based on the Army's UH-60L Black Hawk fuselage mated to the naval Seahawk's folding rotor system, engines, and drivetrain, the Sierra first flew on January 27, 2000, and entered service in February 2002. It was the first Navy helicopter to field a glass cockpit, relaying flight information through four digital monitors. The Navy acquired approximately 275 MH-60S helicopters, and the Sierra's mission list reads like a catalog of everything the fleet needs done: vertical replenishment and cargo transfer, combat search and rescue, naval special warfare support, airborne mine countermeasures, anti-surface warfare, humanitarian disaster relief, medical evacuation, and personnel transport. Its large cabin — inherited from the Black Hawk — can accommodate up to 20 armed troops, and its modular mission kit design allows rapid reconfiguration between roles. Armed variants carry Hellfire missiles, Hydra 70mm rockets, .50-caliber guns, Mk 54 torpedoes, and a nose-mounted FLIR turret. For mine countermeasures, the Sierra deploys the AQS-20A towed sonar and the airborne laser mine detection system. MH-60S Knighthawks first saw combat during Operation Iraqi Freedom in 2003, provided critical relief after the 2010 Haiti earthquake, and continue to deploy aboard carriers, amphibious ships, and littoral combat ships worldwide. Operated by Helicopter Sea Combat (HSC) squadrons, the Sierra is expected to remain the backbone of the Navy's combat support helicopter fleet into the 2030s. Perfect For: MH-60S aircrewmen and pilots, HSC squadron members, former HC and HS squadron veterans, Knighthawk maintainers, and anyone who keeps the fleet supplied and the mission covered.
