HH-60G Pave Hawk


The primary mission of the HH-60G Pave Hawk helicopter is to conduct day or night personnel recovery operations into hostile environments to recover isolated personnel during war. The HH-60G is also tasked to perform military operations other than war, including civil search and rescue, medical evacuation, disaster response, humanitarian assistance, security cooperation/aviation advisory, NASA space flight support, and rescue command and control.

HH-60G Pave Hawk


The Pave Hawk is a highly modified version of the Army Black Hawk helicopter which features an upgraded communications and navigation suite that includes integrated inertial navigation/global positioning/Doppler navigation systems, satellite communications, secure voice, and Have Quick communications.

All HH-60Gs have an automatic flight control system, night vision goggles with lighting and forward looking infrared system that greatly enhances night low-level operations. Additionally, Pave Hawks have color weather radar and an engine/rotor blade anti-ice system that gives the HH-60G an adverse weather capability.

The RDR 1400C weather and search-and-rescue radar was designed for fixed or rotary wing aircraft engaged in patrol, search and rescue missions, and for transporting personnel and equipment to remote sites (off-shore oil rigs etc.) The lightweight digital X-Band radar got the designator AN/APN-239 in the AmericanJETDS . The RDR 1400C color vision weather radar system is manufactured by Telephonics (originally by Bendix/King) and is e.g. used in Sikorsky HH-60G, MH-60G.


RDR 1400C Color vision Weather Radar System provides five primary modes of operation: 2 conventional weather avoidance modes, and 3 air-to-surface and detection modes:

  • Search 1 incorporates special sea clutter rejection circuitry to help detect small boats or buoys down to a minimum range of 300 yards.
  • Search 2 is designed for precision ground mapping, where high target resolution is important.
  • Search 3 mode includes normal ground mapping and can also be used to detect and track prominent land objects and coastlines.

The RDR 1400C also has the capability to receive signals from both standard 2-pulse beacon transponders and the DO-172 6-pulse transponders.

The primary system components of weather radar system are Receiver – Transmitter unit, Radar Control panel, Antenna Drive & Antenna Array and Navigation concentrator. The system is available with one of three flat-plate arrays of different diameter: AA-1218A (10″ or 25 cm), AA-4518A (12″ or 30 cm), and AA-5518A (10″ or 45 cm). The Radar Antenna Drive Unit (DA-1203A) allows pitch/roll stabilization and scans of 120 deg. or 60 deg. sector. The basic aircraft inputs for this radar is 28 V DC, 115 V AC and A/C Gyro inputs.

Pave Hawk mission equipment includes a retractable in-flight refueling probe, internal auxiliary fuel tanks, two crew-served 7.62mm or .50 caliber machineguns, and an 8,000-pound (3,600 kilograms) capacity cargo hook. To improve air transportability and shipboard operations, all HH-60Gs have folding rotor blades.

Pave Hawk combat enhancements include a radar warning receiver, infrared jammer and a flare/chaff countermeasure dispensing system.

HH-60G rescue equipment includes a hoist capable of lifting a 600-pound load (270 kilograms) from a hover height of 200 feet (60.7 meters), and a personnel locating system that is compatible with the PRC-112 survival radio and provides range and bearing information to a survivor’s location.

Pave Hawks are equipped with an over-the-horizon tactical data receiver that is capable of receiving near real-time mission update information.

CRH programme details

The USAF announced the replacement of its aging HH-60G helicopters with new CRH in 2010. A request for proposal (RFP) was issued for the CRH programme in October 2012. Sikorsky teamed up with major subsystems supplier Lockheed Martin to offer a UH-60M derivative as the USAF’s new combat rescue helicopter.

In June 2014, the USAF awarded a $1.2bn engineering, manufacturing and development (EMD) contract to the Sikorsky-Lockheed Martin team to provide the next-generation combat rescue helicopter fleet. The scope of the contract covers development and integration of the rescue mission systems, four helicopters, as well as seven aircrew and maintenance training systems.

The contract also includes options for the production of 112 HH-60W helicopters. The Sikorsky-Lockheed Martin team will deliver the helicopters with most advanced capabilities to support all services in combat.

The new combat rescue helicopter was officially named as the HH-60W by the USAF in November 2014. The preliminary design review (PDR) of the HH-60W was completed in May 2016, whereas the vehicle critical design review (CDR) was concluded in September 2017. The training systems CDR is expected in September 2017.

The USAF plans to conduct the first test flight of HH-60W CRH in 2019 for fielding an operational helicopter in 2021, while full-rate production is anticipated by 2023.

Goodrich AN/AVR-2B(V) Laser Warning System (LWS)


The AN/AVR-2A is a passive laser warning system which receives, processes and displays threat information resulting from aircraft illumination by laser designators, range finders and beam riding missiles. The threat information is displayed on the AN/APR-39A(V)1 Radar Detecting Set indicator in the cockpit. The AN/AVR-2A LDS is derived from the basic AN/AVR-2 LDS through the incorporation of several engineering change proposals (ECPs). These ECPs include: incorporation of the Multiple Integrated Laser Engagement System-Air-to-Ground Engagement System interface; incorporation of a removable user data module to the comparator interface to permit a means to apply software changes and system declassification; and increased Band III sensitivity for improved threat detection performance. The AN/AVR-2A LDS consists of one interface unit comparator and four identical sensor units. The total system weight is 21 pounds.


The AN/AVS-2B(V) was derived from the system developed for the Sikorsky RAH-66 Comanche. Goodrich claimes it is 40% smaller, 45% lighter (i.e. approx. 2,5 pounds (1,5 kg) per sensor) and uses 45% less power than the previous AN/AVR-2A(V) version . The system provides increased functionality for threat detection and data interface and has demonstrated a 500% improvement in reliability. The model was introduced into service in 2004. Source scramble.nl
