Lla Sikorsky SH-60/MH-60 Seahawk (or Sea Hawk) is a twin turboshaft engine, multi-mission United States Navy helicopter based on the United States Army UH-60 Black Hawk and a member of the Sikorsky S-70 family. The most significant airframe modification is a hinged tail to reduce its footprint aboard ships. The U.S. Navy uses the H-60 airframe under the model designations SH-60B, SH-60F, HH-60H, MH-60R, and MH-60S. Able to deploy aboard any air-capable frigate, destroyer, cruiser, fast combat support ship, amphibious assault ship, or aircraft carrier, the Seahawk can handle anti-submarine warfare (ASW), anti-surface warfare (ASUW), naval special warfare (NSW) insertion, search and rescue (SAR), combat search and rescue (CSAR), vertical replenishment (VERTREP), and medical evacuation (MEDEVAC).

Lla « Navalized » Faucon noir
Lla Sikorsky SH-60B Seahawk is the maritime derivative of the U.S. Army’s UH-60 Black Hawk. While they share a similar silhouette, the SH-60B was extensively redesigned to survive the harsh salt-spray environment of the open ocean and to fit onto the cramped flight decks of Navy frigates, destroyers, and cruisers. As the core of the LAMPS Mk III (Light Airborne Multi-Purpose System), the Seahawk acts as a remote sensor and weapon platform, extending a ship’s reach by hundreds of miles.

Key Engineering & Naval Adaptations
- Lla « Short » Wheelbase: To land on small ships, the Seahawk’s tail wheel was moved 13 feet forward compared to the Black Hawk. This shortened its footprint, allowing it to fit onto the rotating « turntable » of the ship’s hangar system.
- RAST System: Lla Recovery Assist, Secure and Traversing system uses a « probe » and a haul-down cable to literally winch the helicopter onto a pitching, rolling deck in heavy seas (up to Sea State 5).
- 25-Tube Sonobuoy Launcher: Unlike the Army version, the left side of the SH-60B features a pneumatic launcher for 25 sonobuoys, used to detect and track submerged submarines.
- Folding Systems: For storage in tight ship hangars, the Seahawk features an electric main rotor blade folding system and a folding horizontal stabilator/tail pylon.
Sensors and Electronic Warfare
- APS-124 Radar: Housed in a prominent « belly » radome, this surface search radar provides the crew with a 360-degree view of the ocean, detecting small targets like periscopes or patrol boats from great distances.
- Lla « FOU » Boom: On the right rear of the fuselage, a towed Magnetic Anomaly Detector (MAD) can be deployed to pinpoint the exact location of a submarine by detecting the disturbance its metal hull causes in the Earth’s magnetic field.
- Hawk Link: A sophisticated digital data link allows the Seahawk to transmit its sensor data back to the parent ship in real-time, effectively allowing the ship’s combat center to « see » through the helicopter’s eyes.
- Retirement: The SH-60B was officially retired from active U.S. Navy service in 2015, replaced by the more advanced MH-60R « Romeo ».
