27 September 2008: A United States Air Force Sikorsky MH-53M Pave Low IV special operations helicopter, serial number 68-8284, assigned to the 20th Expeditionary Special Operations Squadron, flew its final combat mission before being withdrawn from service and retired after 40 years and 12,066.6 flight hours.
The MH-53M Pave Low IV is a variant of Sikorsky’s S-65 heavy-lift military transport helicopter series. Built by Sikorsky in 1968 as one of 40 HH-53C Super Jolly Green Giants for Combat Search and Rescue (CSAR), 68-8284 has been constantly modernized and upgraded. In the Pave Low IV configuration, it is also used for special operations as well as search and rescue.
The MH-53M is a single main rotor, single tail rotor, twin-engine helicopter. It has a crew of six: 2 pilots, 2 flight engineers and 2 gunners. The Pave Low IV is equipped with terrain-following radar and Forward Looking Infrared (FLIR) for low-level operations in darkness and low visibility.
The MH-53M fuselage is 67 feet, 2.4 inches (20.483 meters) long, and the helicopter has a maximum length of 91 feet, 11.34 inches (28.025 meters) with rotors turning and the refueling boom extended. The height to the top of the main rotor pylon is 17 feet, 1.68 inches (5.224 meters). The maximum height (rotors turning) is 24 feet, 10.88 inches (7.592 meters).
The articulated 6-blade main rotor has a diameter of 72 feet, 2.7 inches (22.014 meters). The main rotor turns counter-clockwise at 185 r.p.m. (100% Nr), as seen from above. (The advancing blade is on the helicopter’s right.) The main rotor blades are built with titanium spars and have -16° of twist. The semi-articulated four-blade tail rotor has a diameter of 16 feet, 0 inches (4.877 meters) and is positioned on the left side of the tail pylon. It turns clockwise at 792 r.p.m., as seen from the helicopter’s left side. (The advancing blade is below the axis of rotation.) The gap between rotor arcs is just 4.437 inches (11.270 centimeters).
Empty, the MH-53M weighs 32,000 pounds (14,515 kilograms). Its maximum takeoff weight is 46,000 pounds (20,865 kilograms).
Its two General Electric T64-GE-100 axial-flow turboshaft engines have a Normal Continuous Power rating of 3,810 shaft horsepower at 85 °F. (30 °C.), Military Power rating of 4,090 shaft horsepower, and a Maximum Power rating of 4,330 shaft horsepower. The T64-GE-100 is 79 inches (2.007 meters) long, 20 inches (0.508 meters) in diameter and weighs 720 pounds (327 kilograms). Output (100% N2) is 13,600 r.p.m.
The MH-53M has a maximum speed of 196 miles per hour (315 kilometers per hour) and a service ceiling of 16,000 feet (4877 meters). It carries two 450-gallon (1,703 liter) jettisonable fuel tanks under each sponson.
The MH-53M is armed with two M134 7.62mm miniguns and a GAU-18/A .50 caliber machine gun.
At the time they were retired, the MH-53M was the fastest, heaviest, most powerful helicopter in the United States Air Force inventory.
After leaving Iraq, 68-8284 was transported by C-17 Globemaster III to England. It was loaned to the Royal Air Force Museum Cosford, where it is on display.
1 September 1968: Two U.S. Air Force McDonnell F-4D Phantom II fighters were on a pre-dawn strike against the Ho Chi Minh Trail, near the Ban Karai Pass. Both Phantoms, call signs CARTER 01 and CARTER 02, were hit by anti-aircraft gunfire and their crews had to eject. Both pilots from CARTER 01 were quickly picked up, but the aircraft commander of CARTER 02 was hidden by the jungle. The Weapons System Officer was never seen again.
A Combat Search and Rescue (CSAR) mission was immediately sent out to locate and rescue the missing airmen. Two Sikorsky HH-3 Jolly Green Giant helicopters, the recovery team, were escorted by four Douglas A-1 Skyraiders to help in the search and to suppress any enemy gunfire that was trying to shoot down the rescue helicopters.
The Skyraider was a Korean War era carrier-based attack airplane originally in service with the U.S. Navy. It had been replaced by modern jet aircraft, but the Air Force found that its slow flight and ability to carry a heavy fuel and weapons load were ideal for the CSAR escort mission.
The four Skyraiders were from the 602nd Special Operations Squadron at Nakhom Phanom, Thailand. They operated with the call sign SANDY. Lieutenant Colonel William A. Jones III, the squadron commanding officer, on his 98th combat mission, was the on-scene commander flying SANDY 01, an A-1H, serial number 52-139738.
MEDAL OF HONOR JONES, WILLIAM A., III
Rank and organization: Colonel, U.S. Air Force, 602d Special Operations Squadron, Nakon Phanom Royal Thai Air Force Base, Thailand

Entered service at: Charlottesville, Virginia
Born: 31 May 1922, Norfolk, Virginia
Citation: For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty. Col Jones distinguished himself as the pilot of an A-1H Skyraider aircraft near Dong Hoi, North Vietnam. On that day, as the on-scene commander in the attempted rescue of a downed U.S. pilot, Col. Jones aircraft was repeatedly hit by heavy and accurate antiaircraft fire. On 1 of his low passes, Col. Jones felt an explosion beneath his aircraft and his cockpit rapidly filled with smoke. With complete disregard of the possibility that his aircraft might still be burning, he unhesitatingly continued his search for the downed pilot. On this pass, he sighted the survivor and a multiple-barrel gun position firing at him from near the top of a karst formation. He could not attack the gun position on that pass for fear he would endanger the downed pilot. Leaving himself exposed to the gun position, Col. Jones attacked the position with cannon and rocket fire on 2 successive passes. On his second pass, the aircraft was hit with multiple rounds of automatic weapons fire. One round impacted the Yankee Extraction System rocket mounted directly behind the headrest, igniting the rocket. His aircraft was observed to burst into flames in the center fuselage section, with flame engulfing the cockpit area. He pulled the extraction handle, jettisoning the canopy. The influx of fresh air made the fire burn with greater intensity for a few moments, but since the rocket motor had already burned, the extraction system did not pull Col. Jones from the aircraft. Despite searing pains from severe burns sustained on his arms, hand, neck, shoulders, and face, Col. Jones pulled his aircraft into a climb and attempted to transmit the location of the downed pilot and the enemy gun position to the other aircraft in the area. His calls were blocked by other aircraft transmissions repeatedly directing him to bail out and within seconds his transmitters were disabled and he could receive only on 1 channel. Completely disregarding his injuries, he elected to fly his crippled aircraft back to his base and pass on essential information for the rescue rather than ball out. Col. Jones successfully landed his heavily damaged aircraft and passed the information to a debriefing officer while on the operating table. As a result of his heroic actions and complete disregard for his personal safety, the downed pilot was rescued later in the day. Col. Jones’ profound concern for his fellow man at the risk of his life, above and beyond the call of duty, are in keeping with the highest traditions of the U.S. Air Force and reflect great credit upon himself and the Armed Forces of this country.
The United States Navy and Marine Corps adopted the Douglas Aircraft Company AD-1 Skyraider just after the end of World War II. The U.S. Air Force recognized its value as a close air support attack bomber, but it wasn’t until the early months of U.S. involvement in the Vietnam War that a number of Skyraiders were transferred to the U.S.A.F. These aircraft were identified by Department of the Navy, Bureau of Aeronautics serial numbers, commonly referred to as “bureau numbers,” or “bu. no.” Once acquired by the Air Force, the two-digit fiscal year number in which the airplane was contracted was added to the bureau number, resulting in a serial number with a format similar to a standard U.S.A.F. serial number. For example, Lieutenant Colonel Jones’ Skyraider, A-1H 52-139738, was originally U.S. Navy AD-6 Skyraider Bu. No. 139738, authorized in 1952. (The Douglas AD series was redesignated A-1 in 1962.)
The Douglas AD-6 (A-1H) Skyraider is a single-place, single-engine attack aircraft. A low-wing monoplane with conventional landing gear, it has folding wings for storage aboard aircraft carriers. The A-1H Skyraider is 39 feet, 3 inches long (11.963 meters) with a wingspan of 50 feet, ¼ inch (15.246 meters) and overall height of 15 feet, 8 inches (4.775 meters). Its empty weight is 12,070 pounds (5,475 kilograms) and the maximum weight is 24,000 pounds (10,886 kilograms).
The A-1H is powered by a 3,347.66-cubic-inch-displacement (54.858 liter), air-cooled, supercharged, direct-fuel-injected, Wright Aeronautical Division R-3350-26WA Duplex-Cyclone (Cyclone 18 836C18CA1) twin-row 18-cylinder radial engine, with water/alcohol injection. This engine has a normal power rating of 2,300 horsepower at 2,600 r.p.m at 6,200 feet (1,890 meters), and a takeoff/military power rating of 2,700 horsepower at 2,900 r.p.m. to 3,700 feet (1,128 meters). The engine drives a 13 foot, 6 inch (4.115 meters) diameter, four-bladed Aeroproducts constant-speed propeller though a 0.4375:1 gear reduction. The engine is 4 feet, 7.62 inches (1.413 meters) in diameter and 6 feet, 6.81 inches (2.002 meters) long. It weighs 2,848 pounds (1,292 kilograms), dry.
The A-1H Skyraider has a cruise speed of 180 miles per hour (290 kilometers per hour), a maximum speed of 319 miles per hour (513 kilometers per hour) at Sea Level, and 342 miles per hour (550 kilometers per hour) at 15,400 feet (4,694 meters). The ceiling is 29,400 feet (8,961 meters). Carrying a 2,000 pound (907 kilogram) bomb load, its combat radius is 275 miles (443 kilometers).
The A-1H is armed with four 20 mm M2 autocannon, with two in each outboard wing. The Skyraider can carry a combination of external fuel tanks, gun pods, bombs or rockets on 15 hardpoints.
Douglas built 713 AD-6 Skyraiders at Santa Monica, California.
18 July 1967: For the first time, a U.S. Air Force Sikorsky HH-3E Jolly Green Giant Combat Search and Rescue helicopter refueled in flight from a Lockheed HC-130P Combat King command and control aircraft during an actual rescue mission in Southeast Asia.
21 April 1944: The first military helicopter combat rescue began with Lieutenant Carter Harman, 1st Air Commando Group, being ordered to proceed from Lalaghat, India with his Vought-Sikorsky YR-4B, 43-28247, 600 miles (965 kilometers) to Taro in northern Burma.
Technical Sergeant Ed “Murphy” Hladovcak, pilot of a Stinson L-1A Vigilant liaison airplane, had crashed in the jungle behind Japanese lines while transporting three wounded British soldiers. Lieutenant Harman was assigned to attempt to rescue the four men. It would be a marathon operation.
It took Harman and his Sikorsky 24 hours to arrive at Taro. After a brief rest and dip in the river to cool off, he continued for another 125 miles (202 kilometers) to an airstrip in the jungle called “Aberdeen” which was well behind the enemy lines. It was from here that Sgt. Hladovcak had been operating, flying out wounded soldiers. From Aberdeen, Harman was led to the location of the downed men by another liaison airplane. The survivors were surrounded by Japanese soldiers who had found the crashed airplane and were trying to locate the four men.
Because of the high heat, elevation and humidity increased the Density Altitude, the YR-4B’s air-cooled radial engine was unable to produce its full rated power. Also, the helicopter’s rotor blades were not as effective as they would be at lower density altitudes.
Harman planned to lift one of the survivors out of the clearing in the jungle and fly a short distance to a sand bank where other L-1 or L-5 liaison airplanes could fly them back to Aberdeen. He would repeat the operation until all four men had been rescued. However, it took the rest of the day to airlift just the first two wounded and very sick soldiers.
On the second flight, the helicopter’s engine was overheating and on landing it seized and could not be restarted. Sergeant Hladovcak and the remaining soldier were still in the jungle, Lieutenant Harman was stuck by the river bank and Japanese soldiers were everywhere.
On the morning of 25 April Lieutenant Harman was able to get the helicopter’s engine to start, and again, one at a time, he rescued the two remaining survivors. A liaison plane flew out the wounded soldier while Hladovcak rode along with Harman back to Aberdeen. He had never seen a helicopter before.
For his actions, Lieutenant Carter Harman was awarded the Distinguished Flying Cross.
Sikorsky YR-4B 43-28247 was condemned 31 December 1944.
The Sikorsky YR-4B was a two-place, single-engine helicopter with a single main rotor and an anti-torque tail rotor. The fuselage was 35 feet, 8.375 inches (10.881 meters) long with a main rotor diameter of 38 feet, 0 inches (11.582 meters). The tail rotor was 8 feet, 2.25 inches (2.496 meters) in diameter. Its overall length, with rotors turning, was 48 feet, 3.375 inches (4.716 meters). The helicopter had an overall height of 12 feet, 5 inches (3.785 meters). The empty weight was 2,020 pounds (916 kilograms) and maximum takeoff weight of 2,540 pounds (1,152 kilograms). The helicopter’s fuel capacity was 30 gallons (113.6 liters)
The main rotor consisted of three tapered, fully-articulated blades built of chrome-molybdenum steel spars and spruce plywood ribs, with laminated spruce, balsa and mahogany forming the leading edge and a flexible cable forming the trailing edge. The blades were covered with two layers of doped fabric. The three-bladed semi-articulated tail rotor was built with a spruce spar and alternating laminations of maple and mahogany, covered with fabric. Both the main and tail rotors had a thin brass abrasion strip covering the leading edges. The main rotor turned counter-clockwise, as seen from above. (The advancing blade is on the helicopter’s right.) The tail rotor was mounted on the helicopter’s right side in a tractor configuration. It turned clockwise as seen from the helicopter’s left. (The advancing blade is below the axis of rotation.)
The YR-4B was powered by an air-cooled, direct-drive 555.298-cubic-inch-displacement (9.100 liter) Warner Super Scarab SS185 (R-550-3) seven-cylinder radial engine with a compression ration of 6.20:1. The R-550-3 was rated at 185 horsepower at 2,175 r.p.m. at Sea Level, and 200 horsepower at 2,475 r.p.m (five minute limit) for takeoff. The engine was placed backwards in the aircraft with the propeller shaft driving a short driveshaft through a clutch to a 90° gear box and the transmission. The R-550-3 weighed 344 pounds (156 kilograms).
The R-4B had a cruise speed of 65 miles per hour (105 kilometers per hour) and maximum speed of 82 miles per hour (132 kilometers per hour). The service ceiling was 12,000 feet (3,658 meters) and range was 157 miles (253 kilometers).
The YR-4B was equipped with bomb racks. It could carry three 125 pound (56.7 kilogram) demolition bombs or one 325 pound (147 kilogram) depth bomb. The equipment was deleted for the R-4B.
Sikorsky built 27 YR-4Bs and 100 R-4B helicopters. Of these, 40 were assigned to the Army Air Corps, 19 to the Navy and Coast Guard, and 41 were sent to the Royal Air Force and Royal Navy.
Carter Harman was born at Brooklyn, New York, 14 June 1918, the son of Steven Palmer Harman, a newspaper editor, and Helen F. Doremus Harman.
Before the war, Harman had been a musician and author. He assisted Duke Ellington write an autobiography. Harman earned a bachelor’s degree in music composition from Princeton University, Princeton, New Jersey, in 1940.
Harman enlisted as a private in the Army of the United States Army on 1 April 1942, assigned to the Air Corps. Enlistment records indicate that he was 5 feet, 7 inches (170.2 centimeters) tall and weighed 125 pounds (57 kilograms)
After World War II ended, Harman returned to his musical studies at Columbia University, New York City, receiving a master’s degree in 1949.
Harman worked as a music critic for The New York Times and Time Magazine, and also continued writing books, as well as composing for ballet and opera. He was also a music producer and became executive vice president of CRI Records (Composers Recordings, Inc.).
Harman was married three times. He married Miss Nancy Hallinan, 5 February 1946, however they later divorced. His second wife was Helen Scott. They had four children together. His third wife was Wanda Maximilien.
Carter Harman died at Berlin, Vermont, 23 January 2007 at the age of 88 years.
30–31 March 1979: That Others May Live. On a dark and stormy night in the Yellow Sea, between China and the Korean Peninsula, the 160 foot (49 meter), 3,000 ton (2,722 Metric tons) Taiwanese freighter Ta Lai ran aground. As 20 foot (6 meters) waves battered the stranded ship, rocks punched through the hull. It was taking on water and sinking. Her crew of twenty-eight men were in danger.
Detachment 13, 33rd Aerospace Rescue and Recovery Squadron, at Osan Air Base, 40 miles (64 kilometers) south of Seoul, the capital of the Republic of South Korea, answered the distress call.
Major James E. McArdle, Jr., United States Air Force, and his crew of four, flew their helicopter, “Rescue 709,” a Sikorsky HH-3E Jolly Green Giant, serial number 67-14709, through the darkness and gale-force winds to the stranded vessel. These men were just completing there regular 12-hour duty schedule when the distress call came in, but no other crews or helicopters were available.
In addition to Major McArdle, the aircraft commander, the crew consisted of 1st Lieutenant Van J. Leffler, pilot; Sergeant James E. Coker, flight engineer; Staff Sergeant Tony Carlo and Sergeant Mark Zitzow, pararescue jumpers (“PJs”).
Rescue 709 arrived on scene just before midnight, 30 March. While McArdle and Leffler tried to hold a steady hover over the Ta Lai as it pitched and rolled in the storm, Sergeant Zitzow was lowered 80 feet (24 meters) to the deck. Once there, he assisted the ship’s crew, two at a time, onto the rescue hoist’s jungle penetrator, and after strapping them on, all three were hoisted back to the helicopter. Sergeant Coker, who was controlling the hoist, moved the sailors into the passenger/cargo area of the Jolly Green Giant, and Zitzow was once again lowered to the Ta Lai.
With ten survivors aboard Rescue 709, the helicopter was at its maximum load. Sergeant Zitzow remained aboard Ta Lai. The crew then flew to Kwang-Ju Air Base, 150 miles (241 kilometers) south of Seoul—more than 30 minutes away—to offload the men.
After returning to the rescue scene, Sergeant Zitzow was joined on deck by Sergeant Carlo. While lifting three sailors, the helicopter’s hoist motor overheated and stopped. The sailors were still hanging 50 feet (15 meters) underneath the Jolly Green Giant. The only thing that could be done was to fly to a small island about 2 miles (3.2 kilometers) away and lower them to the ground. 709 then returned to the ship, by which time the hoist was working again. They picked up several more sailors and with Carlo once again on board, made the flight to Kwang-Ju.
On the third trip, the winds, though still high, were blowing from a more advantageous direction, and the final twelve men, including Zitzow, were quickly picked up. Rescue 709 returned to Kwang-Ju and landed at 0415 hours, 31 March 1979.
For this rescue, Major McArdle was awarded the Mackay Trophy by the National Aeronautic Association, for the most “meritorious flight of the year” by an Air Force member, members, or organization. He was also awarded another Distinguished Flying Cross. Lieutenant Leffler and Sergeant Coker were awarded the Air Medal, while both Sergeants Zitzow and Coker received the Airman’s Medal.
67-14709 was built by Sikorsky Aircraft Corporation at Straford, Connecticut as a CH-3E transport helicopter and was later converted to the HH-3E configuration. It served the United States Air Force from 3 July 1968 to 19 February 1991.
During the Vietnam War, 709 operated with the 37th ARRS at Da Nang in the Combat Search and Rescue (CSAR) role. Flying with the call sign “Jolly Green 22,” at least 27 airmen were rescued by this helicopter and its crews.
During that period, crewmen assigned to 709 were awarded one Air Force Cross,¹ fourteen Silver Stars (three of these had been nominated for the Air Force Cross) and an unknown number of Purple Hearts. On one mission alone, 709 took hits from at least 68 machine gun bullets.
After Operation Desert Storm, 709 was sent to The Boneyard at Davis-Monthan Air Force Base, Tucson, Arizona. After 19 years in the desert, in August 2010, she was pulled from storage and sent to the National Museum of the United States Air Force for a 6-month restoration by Museum staff, as well as technical experts from the 20th Special Operations Squadron at Hurlbert Field, Florida.
Sikorsky HH-3E 67-14709 is on display in the Southeast Asia War Gallery of the Museum at Wright-Patterson Air Force Base, Ohio. Colonel McArdle, her pilot during the 1979 rescue mission, was present at 709’s Museum debut, 14 December 2010.
Colonel James E. McArdle, Jr., was born at LaCrosse, Wisconsin, 2 March 1943. He attended Marquette University High School in Milwaukee, where he competed on the Swimming Team and worked on the student newspaper. He entered the United States Air Force Academy as a cadet in 1961, majoring in engineering management. Upon graduating from the Academy, 9 June 1965, he was presented the Secretary of the Air Force Award for Behavorial Sciences. McArdle was commissioned as a Second Lieutenant, United States Air Force.
2nd Lieutenant McArdle trained as a helicopter pilot at Randolph Air Force Base, Texas, finishing at the top of his class. After finishing advanced helicopter training at Sheppard AFB, Texas, McArdle was assigned to the 20th Helicopter Squadron, 14th Air Commando Wing, operating in Southeast Asia, where he flew the Sikorsky CH-3C transport helicopter. He was awarded the Distinguished Flying Cross, four Air Medals and the Air Force Commendation Medal.
In 1970, McArdle was retrained as a Northrop T-38A Talon pilot and spent the next four years as an instructor and check pilot at Williams Air Force Base, Arizona.
Assigned to the Air Force Reserve Officer Training Corps from 1974 to 1978, Major McArdle was next assigned as operations officer for Detachment 13, 33rd Aerospace Rescue and Recovery Squadron, Osan Air Base, Korea. During a 12-month period, the detachment saved 80 lives, including those rescued from the Ta Lai.
From 1979 to 1981 Lieutenant Colonel McArdle served at headquarters, Aerospace Rescue and Recovery Service, Scott Air Force Base, Illinois. While there he developed combat rescue tactics and helped develop the MH-53J Pave Low and MH-60G Pave Hawk special operations helicopters.
As operations officer of the 67th Aerospace Rescue and Recovery Squadron at RAF Woodbridge, Suffolk, England, McArdle supervised three detachments. Next, Lieutenant Colonel McArdle assumed command of the 41st ARRS at McClellan Air Force Base, Sacramento, California, 7 August 1984. At that time, unit’s primary assignment was special operations support, the only helicopter squadron so assigned in the U.S. Air Force.
Colonel McArdle’s final assignment was as Inspector General at McLellan Air Force Base. He retired from the U.S. Air Force on 1 August 1991 after thirty years of service.
The SH-3A Sea King (Sikorsky S-61) first flew 11 March 1959, designed as an anti-submarine helicopter for the U.S. Navy. The prototype was designated XHSS-2 Sea King. In 1962, the HSS-2 was redesignated SH-3A Sea King. Many early production aircraft were upgraded through SH-3D, SH-3G, etc. In addition to the original ASW role, the Sea Kings have been widely used for Combat Search and Rescue operations. Marine One, the call sign for the helicopters assigned to the President of the United States, are VH-3D Sea Kings.
The Sikorsky HH-3E (Sikorsky S-61R) earned the nickname Jolly Green Giant during the Vietnam War. It is a dedicated Combat Search and Rescue (CSAR) helicopter flown by the U.S. Air Force, based on the CH-3C transport helicopter. The aircraft is flown by two pilots and the crew includes a flight mechanic and gunner. It is a large twin-engine helicopter with a single main rotor/tail rotor configuration. It has retractable tricycle landing gear and a rear cargo ramp. The rear landing gear retracts into a stub wing on the aft fuselage. The helicopter has an extendable inflight refueling boom.
