HH-60G Pave Hawk

Mission

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

Features

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.

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.

Weapon systems

The LPH is armed with RIM-116 RAM (rolling airframe missile) system. RAM is an infrared homing surface-to-air missile used against anti-ship cruise missiles.

The missile can travel at a maximum speed of Mach 2 while carrying a blast fragmentation warhead for a range of 9km. The ship is also fitted with two goalkeeper close-in weapon systems (CIWS) supplied by Thales Nederland. The system provides close-point defence against incoming missiles and ballistic shells. The seven barrelled CIWS can fire 4,200 rounds a minute for a maximum range of 2,000m.

RIM-116 Rolling Airframe Missile Block 1

45cf37c0b1478495adec4c08f793a34d

The RAM program is designed to provide surface ships with an effective, low-cost, lightweight, self-defense system which will provide an improved capability to engage and defeat incoming antiship cruise missiles (ASCMs). RAM is a joint United States and German venture to design an effective, low cost, lightweight quick-reaction, self-defense system which will increase the survivability of otherwise undefended ships. It is a 5 inch missile that utilizes SIDEWINDER technology for the warhead and rocket motor, and the STINGER missiles seeker. Cueing is provided by the ships ESM suite or radar. The MK-31 RAM Guided Missile Weapon System (GMWS) is defined as the MK-49 Guided Missile Launching System (GMLS) and the MK-44 Guided Missile Round Pack (GMRP).

b25348765aba32b1c49da4d02f38657c

The RAM Block 0 has a five-inch diameter airframe that rolls in flight and dual mode, passive radio frequency/infrared (RF/IR) guidance. Initial homing for RAM Block 0 is in RF, using an ASCM’s RF seeker emissions. If the ASCM’s IR radiation is acquired, RAM transitions to IR guidance.

eb834c0058a4ede2bf8325703cf971ab

Effective against a wide spectrum of existing threats, the RAM Block 1 IR upgrade incorporates a new IR “all-the-way-homing” guidance mode to improve AW performance against evolving passive and active ASCMs. The Block 1 missile retains all capabilities of the Block 0 missile while adding two guidance modes, IR only and IR Dual Mode Enable (IRDM). The IR only mode guides on the IR signature of the ASCM. The IRDM will guide on the IR signature of the ASCM while retaining the capability of utilizing RF guidance if the ASCM RF signature becomes adequate to guide on. RAM Block I can be launched in an IR all-the-way mode, as well as the dual mode (passive RF, followed by passive IR) used by Block 0.

Goalkeeper close-in weapon systems (CIWS)

The system automatically performs the entire process from surveillance and detection to destruction, including selection of the next priority target. The crucial importance of a last-ditch defence system has been proven on numerous occasions. To provide for this need, Thales developed Goalkeeper, an extremely effective system, that incorporates the 30 mm, 7-barrel Gatling gun with special missile-piercing ammunition. The combination of MPDS ammunition and a firing rate of 4200 rds/min gives the system the power necessary to destroy missile warheads.

Goalkeeper provides excellent performance against surface targets. Search and track radars, weapon control and integration of the total system are Thales’ strengths. A high detection probability for small targets is ensured in all weather conditions by the use of an I-band search radar. Pin-point target tracking is achieved by the dual frequency I/K-band track radar. Continuous search with track-while-scan ensures rapid engagement of the next priority target in multitarget scenarios.

Goalkeeper’s capabilities have been proven many times during sea-going trials. U.S. trials in which 3 types of live missiles were destroyed by Goalkeeper, conclusively confirmed the capabilities of this proven Close-In Weapon System.

Goalkeeper is operational in the navies of Belgium, Chile, the Netherlands, Portugal, Qatar, South Korea, the UAE and the UK.

Korean Surface-to-Air Anti-Missile (SAAM, or K-SAAM)

SAAM is a homing missile mounted on surface ships to intercept multiple homing missiles, aircraft, warships and guided bombs fired toward friendly ships, capable of engaging multiple targets simultaneously. Although the existing homing missiles mounted on surface ships to intercept homing missiles fired toward friendly ships are mostly introduced from abroad, the R&D project is underway in Korea to develop domestic surface-to-air anti-missiles that are superior in performance, stable in production and low in cost.
