Seahawk MH-60

The twin-engine Seahawk is a do-it-all machine. This isn't even the full chore list:

  • Anti-submarine warfare
  • Search and rescue
  • Drug interdiction
  • Anti-ship warfare
  • Cargo lift
  • Early warning
  • Medevac
  • Special Operations

Seahawks can land on or fly to almost any Navy ship or base. They buzz back and forth around a fleet, moving personnel, parts and other mission-critical items between vessels and shore.

The Seahawk exists in two variants: the rugged MH-60 and the newer MH-60R. The newest model will be equipped with a more sensitive radar array. However, the cockpits are identical so pilots can seamlessly fly either platform.

Features

The Sea Hawk is a twin-engine helicopter. It is used for anti-submarine warfare, search and rescue, drug interdiction, anti-ship warfare, cargo lift, and special operations. The Navy's SH-60B Sea Hawk is an airborne platform based aboard cruisers, destroyers, and frigates and deploys sonobuoys (sonic detectors) and torpedoes in an anti-submarine role. They also extend the range of the ship's radar capabilities. The Navy's SH-60F is carrier-based. The HH-60H, also aboard carriers and ashore, is used for search and rescue (SAR) missions. By 2015, the only models of Sea Hawk in the Navy will be the MH-60S and the MH-60R. Some versions, such as the Air Force's MH-60 G Pave Hawk and the Coast Guard's HH-60J Jayhawk, are equipped with a rescue hoist with a 250 foot (75 meter) cable that has a 600 pound (270 kg) lift capability, and a retractable in-flight refueling probe. The Army's UH-60L Black Hawk can carry 11 soldiers or 2,600 pounds (1,170 kg) of cargo or sling load 9,000 pounds (4,050 kg) of cargo.

Background

The UH-60 Black Hawk was fielded by the Army in 1979. The Navy received the SH-60B Sea Hawk in 1983 and the SH-60F in 1988. The first MH-60S operational squadron was Helicopter Combat Support Squadron Five (HC 5), homeported in Guam. The Air Force received the MH-60G Pave Hawk in 1982 while the Coast Guard received the HH-60J Jayhawk in 1992.
