Mh-53 Pave Low - The Sikorsky MH-53 Pave Low Series is a long-retired special operations and search and rescue (CSAR) helicopter for the United States Air Force. This system was developed from the HH-53B/C, a variant of the Sikorsky CH-53 Sea Stallion. The HH-53 "Super Jolly Gray Giant" was designed to replace the HH-3E "Jolly Gray Giant". The US Air Force MH-53J/M was retired in September 2008.
The US Air Force ordered 72 HH-53B and HH-53C variants for search and rescue units during the Vietnam War and developed the MH-53J Pave Low version for special operations.

The Pave Low mission is to enter low-level, long-range, inhospitable areas in adverse weather conditions for the insertion, extraction, and recovery of special forces. Pave Lows often work in conjunction with the MC-130H Combat Talon for navigation, communications and combat support.

The giant gray air HH-53B earned the nickname "Super Jolly Gray Giant". The name refers to the small HH-3E "Jolly Gray Giant", an extended version of the H-3 Sea King used in search and rescue (CSAR) operations in the Vietnam War.
The US Air Force appreciates the long-range Sikorsky S-61R/HH-3E "Jolly Gray Giant" CSAR helicopter and prefers the more capable S-65/CH-53A. In 1966, the USAF awarded Sikorsky a contract to develop the CSAR variant of the CH-53A.

The original HH-53B had T64-GE-3 turboshafts rated at 3,080 hp (2,297 kW) each, but these tanks were later upgraded to T64-GE-7 turboshafts rated at 3,925 hp (2,927 kW). . A crew of five is standard, including a pilot, co-pilot, crew chief and two rescuers.
Mh 53 Pave Low Historical Marker
The HH-53B is a short-lived model, with production quickly transitioning to the Air Force HH-53C CSAR model. The only visible difference between the HH-53B and HH-53C is the HH-53C's elimination of the fuel delivery brackets. Experience with the HH-53B showed that the original tank was too large, which adversely affected refueling performance, so a 450 US gal (1,703 L) tank was adopted. Other changes include more weapons and a comprehensive radio system to improve communication with C-130 aircraft, CSAR support aircraft, and air crews awaiting rescue on the ground. The HH-53C, on the other hand, is similar to the HH-53B with the more powerful T64-GE-7 version.
A total of 44 HH-53Cs were built, entering service in August 1968. At the end of the war, they were equipped with pods designed to combat heat-seeking missiles. As with the HH-53B, the HH-53C is used for stealth missions and frequent drop-off capsules, as well as reconnaissance drones. Many were assigned to support the Apollo space program, standing by to retrieve the Apollo capsule in case the launch pad shut down, although no such accident occurred.
In addition to the HH-53Cs, the Air Force acquired 20 CH-53C helicopters for additional cargo operations. The CH-53C can be similar to the HH-53C and retain the rescue surface, the most notable of which is that the CH-53C does not have an in-flight fuel monitor. Since the CH-53C is used for stealth operations, weapons and ammunition are used like the HH-53C.
PAVE or Pave is the Air Force code name for a weapon system that uses advanced electronics.

The USAF's Super Jollies are useful helicopters, but they are day/fair weather helicopters, and pilots who shoot them down often have problems at night or in bad weather. A night/dark radar system, called "Pave Low I" based on a low-level TV viewer (LLLTV), was installed in Southeast Asia in 1969 and compared the attack on the Super Jolly, but the reliability was insufficient.
In 1975, one HH-53B was successfully fitted with the "Pave Low II" system and redesignated the YHH-53H. This performance proved satisfactory and therefore eight HH-53Cs were installed with improved systems and designated HH-53H Pave Low III, YHH-53H was also upgraded to this specification. They were all imported in 1979 and 1980.
The HH-53H retained the in-flight refueling probe, external fuel tank, pump, and three weapons of the HH-53C; armament is usually a small gun on each side and a brown .50-inch (12.7 mm) gun in the tail to provide greater range and anti-aircraft capability. Upgrades featured by the HH-53H include:
The FLIR and TFR are mounted on different "colored" mounts. The HH-53H can accommodate 27 seats for soldiers or 14 liters. The Navy and Psakola made the improvements, reflecting the high level of the Navy's work on the S-65 of the Air Force. In 1986, the surviving HH-53Hs were updated under the CONSTANT GRE program and included other upgrades such as a blue cockpit fitted with night vision goggles (NVG). They were reclassified as "special performance" vehicles and given the new designation MH-53H accordingly.

The HH-53H proved itself and the Air Force decided to order more, the MH-53J came with the Pave Low III upgrade configuration. The general design of the MH-53J is similar to that of the HH-53J, the main changes being twin T64-GE-415 turboshafts of 4,380 shp (3,265 kV) each, and more weapons. providing a total armor weight of 1,000 lb (450 kg). There are also some flight upgrades, including compatibility with modern Global Positioning System (GPS) satellite navigation receivers. A total of 31 HH-53Bs, HH-53Cs and CH-53Cs were upgraded to the MH-53J configuration from 1986 to 1990, and all MH-53Hs were also upgraded, giving a total of 41 MH-53Js.

The MH-53J Pave Low III helicopter is the largest, most powerful, and most technologically advanced transport helicopter in the US aviation inventory. Ground tracking and radar avoidance, continuous infrared ssor, inertial navigation system and Global Positioning System and projected map display allow the crew to follow the terrain and avoid obstacles and make the lower the petrification.

As part of the Pave Low III program, the Air Force converted nine MH-53Hs and 32 HH-53s for night and inclement weather operations. Modifications include the AN/AAQ-18 forward-looking infrared, inertial navigation system, global positioning system, Doppler navigation system, APQ-158 ground tracking and avoidance radar, on-board information computer, advanced navigation systems and integrated aircraft. navigate the right path to and from the target area. The Air Force designated the modified version as the MH-53J.
The primary mission of the MH-53J is to drop, supply and mobilize special forces behind emy lines. It can also measure in search and rescue operations. Low petrification is possible thanks to modern ground after radar, and infrared light that allows the helicopter to operate in bad weather conditions. It is made of military camouflage. It can carry 38 soldiers at a time and can carry a payload of 20,000 kilograms (9,000 kg) with external hooks. It can reach a maximum speed of 165 mph (266 km/h) and has a ceiling of 16,000 ft (4,900 m).
The MH-53M Pave Low IV was modified from the MH-53J configuration by adding an Interactive Defenseless Avionics System/Multi-Mission Advanced Tactical Terminal or IDAS/MATT. The system improved the protective capacity of Pave Low. It provided immediate access to the overall war situation through the Wartime Electronic Updates. It also provided a new level of anti-detection and threat communication that occurs soon, so the crew can avoid and defeat threats in other ways if necessary.
While awaiting delivery of the HH-53Bs, the Air Force received two CH-53As for research and training. The first of eight HH-53Bs made its first flight on 15 March 1967, and by the end of the year, the type was flying CSAR and the USF Aerospace Rescue and Recovery Service in Southeast Asia. The Air Force calls the HH-53B the "Super Jolly." It has been used for CSAR, covert military operations, and to "intercept" test capsules from photo-research satellites.

The Air Force lost 17 Super Joys during the Southeast Asian war, 14 in combat, including one shot down by a North Vietnamese MiG-21 during CSAR operations in Laos on January 28, 1970, and three in accidents .
The Super Jollies made headlines in November 1970 in a failed raid in North Vietnam to rescue POWs from the Son Tay prison camp, and in a mission to rescue the crew of the SS Mayaguez from the Cambodian Khmer Rouge. May 1975.
The HH-53B, HH-53C, and CH-53C remained in Air Force service until the late 1980s. Super Jollies are painted on the front in a variety of colors, while those in state rescue service are generally painted gray with a yellow tail.
The first nine HH-53H Pave Lows entered service on 1 July 1980 and were delivered here.
