The Firehawk is a specialized fire-fighting helicopter platform developed by Sikorsky and based on the company's S-70/UH-60 "Black Hawk" twin-engine transport airframe. The latest variant being offered is based in the S-70i manufactured under license by Sikorsky subsidiary PZL Mielec of Poland. Earlier marks include the S-70A and S-70C Firehawks.
The Firehawk's design includes an external rescue hoist off the starboard side of the fuselage. Internally, it seats its two pilots side-by-side at the front and a complete fire crew of twelve in the passenger section. The hold can also carry up to two medical litters and limited staff for the MEDEVAC role. The Rockwell Collins-designed cockpit supports Night-Vision (NV) equipment, a digital automatic flight control system and is of an all-modern, all-glass design. A tactical communications system provides the operating crew with a link to ground units. A searchlight is available for low-light-level and nighttime operations. Under the fuselage is housed a 1,000 gallon water tank with a built-in retractable snirkel capable of filling said tank in under a minute. The tank a development of Aero Union of Chico, California.
Externally, the Firehawk series retains much of the form-and-function of the U.S. Army's Black Hawk transport series. It sports a twin engine side-by-side layout driving a four-bladed (wide-chord) main rotor assembly over the passenger section and a four-bladed anti-torque rotor unit at the tail (facing starboard). The undercarriage is wheeled, fixed in flight and of a tail-dragger arrangement (also designed to clear the under-belly water tank). The aircraft includes the usual window fittings to provide the best situational awareness possible for pilots and crew. The pilots enter-exit by way of hinged automobile-style doors while access to the passenger section is by way of the traditional sliding doors.
Power is from 2 x General Electric T700-701D series turboshaft engines developing 1,940 horsepower each.

September 2018 - With ongoing fires in California, United Rotorcraft will be converting a pair of former United States Army HH-60L Black Hawk helicopters to the Firehawk role for the Ventura County Fire Department. These are set to be delivered sometime in 2019.
