The MEDAL OF HONOR to

Lieutenant Clyde E. Lassen, United States Navy

For service as set forth in the following

CITATION

For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty on 19 June 1968 as pilot and aircraft commander of a search and rescue helicopter, attached to Helicopter Support Squadron Seven, Detachment One Hundred Four, embarked in USS Preble (DLG 15), during operations against enemy forces in North Vietnam.

Launched shortly after midnight to attempt the rescue of two downed aviators, Lieutenant (then Lieutenant, Junior Grade) Lassen skillfully piloted his aircraft over unknown and hostile terrain to a steep, tree-covered hill on which the survivors had been located.

Although enemy fire was being directed at the helicopter, he initially landed in a clear area near the base of the hill, but, due to the dense undergrowth, the survivors could not reach the helicopter. With the aid of flare illumination, Lieutenant Lassen successfully accomplished a hover between two trees at the survivor’s position. Illumination was abruptly lost as the last of the flares were expended, and the helicopter collided with a tree, commencing a sharp descent.

Expertly righting his aircraft and maneuvering clear, Lieutenant Lassen remained in the area, determined to make another rescue attempt, and encouraged the downed aviators while awaiting resumption of flare illumination. After another unsuccessful, illuminated, rescue attempt, and with his fuel dangerously low and his aircraft significantly damaged, he launched again and commenced another approach in the face of the continuing enemy opposition.

When flare illumination was again lost, Lieutenant Lassen, fully aware of the dangers in clearly revealing his position to the enemy, turned on his landing lights and completed the landing. On this attempt, the survivors were able to make their way to the helicopter. Enroute to the coast, Lieutenant Lassen encountered and successfully evaded additional hostile antiaircraft fire and, with fuel for only five minutes of flight remaining, landed safely aboard USS Jouett (DLG 29).

His courageous and daring actions, determination, and extraordinary airmanship in the face of great risk sustain and enhance the finest traditions of the United States Naval Service.

Lieutenant (Junior Grade) Clyde Everett Lassen was the Officer in Charge of Detachment 104 of Helicopter Support Squadron SEVEN (HC-7), the “Sea Devils,” aboard USS Preble (DLG-15). The assignment was Combat Search and Rescue.

McDonnell F-4J-31-MC Phantom II, Bu. No. 153856, of Fighter Squadron Thirty-Three (VF-33) lands aboard USS America (CVA-66) circa 1968. This Phantom is a squadron mate of Root Beer 210.

This Phantom is a squadron mate of Root Beer 210. (U.S.Navy)

On the night of 18/19 June 1968, a flight of three aircraft from the aircraft carrier USS America (CV-66) were on a bombing mission over North Vietnam. Root Beer 210 was a McDonnell Douglas F-4J-33-MC Phantom II, Bu. No. 155546, flown by Lieutenant Commander John “Claw” Holtzclaw and Lieutenant Commander John A. “Zeke” Burns. Shortly after midnight, two SA-2 surface to air missiles were fired at the Phantom. Holtzclaw and Burns evaded them, but a third missile detonated very close to the fighter bomber, destroying the outer one-third of the right wing. With their airplane critically damaged and on fire, the two naval aviators were forced to eject over enemy territory. They parachuted into a rice paddy and could hear enemy soldiers talking nearby. Burns had suffered a broken leg as well as other injuries.

Aboard the guided missile frigate USS Preble (DLG-15), Lieutenant (junior grade) Clyde Lassen and his flight crew were awakened and assigned to rescue the crew of Root Beer 210, 70 miles (113 kilometers) away in total darkness. Lassen and his co-pilot, Lieutenant (j.g.) LeRoy Cook and gunners Aviation Electrician’s Mate 2nd Class (AE2) Bruce Dallas and Aviation Machinist’s Mate 3rd Class (ADJ3) Don West, took off from Preble at 0022 hours aboard their Kaman SH-2A Seasprite helicopter, call sign Clementine Two, and were vectored by radar to the location of the downed aircrew. The glow of the burning Phantom could be seen from 30 miles (48 kilometers) away. They arrived on scene at 0141 hours. Holtzclaw and Burns were in immediate need of rescue as the enemy was closing in.

Holtzclaw and Burns were on a hillside covered with very tall trees, making it impossible for the Seasprite to land. Parachute flares dropped by supporting aircraft illuminated the area. The pickup would have to be made using a “jungle penetrator” attached to the helicopter’s rescue hoist. But the single-engine helicopter was already fully loaded with its four-man crew and their weapons and ammunition. It could not pick up both fliers while hovering out of ground effect above the trees. Lassen ordered his co-pilot to dump fuel to reduce the weight.

As Lassen hovered into position to make the hoist pickup, the overhead flares went out, leaving the jungle totally dark. Unable to see, Lassen collided with a tree causing damage to the horizontal stabilizer and the right side cabin door. He narrowly avoided a crash.

Clementine Two moved away while they awaited the arrival of another flare aircraft. They were soon engaged by enemy ground fire and the helicopter gunners returned fire with their M-60 machine guns.

On several occasions, Lassen landed the SH-2A in a rice paddy to pickup Holtzclaw and Burns, but enemy gunfire prevent them from reaching the helicopter, which repeatedly had to pull back.

Finally, the crew of Root Beer 210 found their way to the bottom of the slope and Clementine Two landed in a rice paddy about 60 yards (55 meters) away. A fierce firefight between the North Vietnamese soldiers and the gunners of the Navy helicopter took place. Lassen held the Seasprite in a hover to prevent it from sinking into the mud. The gunners jumped down to assist Holtzclaw and Burns aboard. As soon as they were loaded, Lassen immediately took off and left the area, climbed to 4,000 feet (1,220 meters) and headed toward the South China Sea, twenty miles (32 kilometers) away. The helicopter had only thirty minutes of fuel remaining. During the flight, the right cabin door, which had been damaged when the helicopter hit the tree, came off and fell away into the darkness.

Clementine Two was too far away to make it back to Preble, so they turned toward USS Jouett (DLG-29). Commander Destroyer Squadron One, Captain Robert Hayes, commanding Jouett, turned his ship toward the shore and proceeded at full speed, turning on all of the ship’s lights so that Lassen would be able to find it. Jouett came within 3 miles (4.8 kilometers) of the beach. With almost no fuel remaining, Lassen made a straight-in approach and landing.

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.

The type was redesignated L-1A Vigilant in April 1942. The L-1A was expensive to manufacture, but had excellent short field performance. (U.S. Air Force)

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, which increased the density altitude, the YR-4B’s air-cooled engine was unable to produce its full rated power. Also, the helicopter’s rotor blades were not as effective as they would have beeen 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 pick them up and 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 ratio 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.

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.

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.

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.

Major McArdle was assigned to the Air Force Reserve Officer Training Corps from 1974 to 1978. Next, he became the 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.

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) is a development of the SH-3A. It 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.

Beginning in 1928, an American food company began using a cartoon figure to advertise its “Green Giant” brand of canned peas. Eventually the mascot represented The Green Giant Company’s other canned and frozen vegetables. The character is now owned by General Mills.

The HH-3E has an empty weight of 13,341 pounds (6,051 kilograms). The maximum gross weight is 22,050 pounds (10,002 kilograms).

The Jolly Green Giant is powered by two General Electric T58-GE-5 turboshaft engines, which have a Maximum Continuous Power rating of 1,400 shaft horsepower, each, and Military Power rating of 1,500 shaft horsepower. The main transmission is rated for 2,500 horsepower, maximum.

The HH-3E has a cruise speed of 154 miles per hour (248 kilometers per hour) at Sea Level, and a maximum speed of 177 miles per hour (285 kilometers per hour), also at Sea Level. The service ceiling is 14,000 feet (4,267 meters). The HH-3E had a maximum range of 779 miles (1,254 kilometers) with external fuel tanks.

The Jolly Green Giant can be armed with two M60 7.62 mm machine guns.

Sikorsky built 14 HH-3Es. Many CH-3Cs and CH-3Es were upgraded to the HH-3E configuration. Sikorsky built a total of 173 of the S-61R series.

15 March 1967: The first Sikorsky HH-53B, 66-14428, made its maiden flight at Stratford, Connecticut. In the cockpit were Sikorsky test pilots James R. (“Dick”) Wright and Patrick A. Guinn. The helicopter would be called the “Super Jolly Green Giant.”

A variant of the United States Navy/Marine Corps CH-53A Sea Stallion, the Super Jolly Green Giant was the largest, most powerful, and fastest helicopter in the United States Air Force inventory. Configured for combat search and rescue (CSAR) and special operations, the HH-53B was equipped for inflight refueling and was armed with three General Electric GAU/2A 7.62 mm miniguns or .50-caliber Browning machine guns. The HH-53B can be visually distinguished from other H-53s by the two diagonal sponson support struts on each side of the fuselage.

The HH-53B Super Jolly Green Giant was flown by two pilots and was crewed by a flight engineer/gunner, two additional gunners, and one or two pararescue jumpers (“PJs”). It has an overall length of 88 feet, 2.4 inches (26.833 meters) with rotors turning. With the refueling boom extended the total length of the helicopter is 91 feet, 11.34 inches (28.025 meters). The fuselage is 67 feet, 2.4 inches (20.483 meters) long and 8 feet (2.438 meters) wide. 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 HH-53B’s fully-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).

The HH-53B had an empty weight of 26,500 pounds (12,020 kilograms). Its maximum takeoff weight was 42,000 pounds (19,051 kilograms).

The HH-53B was originally equipped with two General Electric T64-GE-3 turboshaft engines, producing 3,080-shaft horsepower, each. The T64 is an axial flow free-turbine turboshaft engine. It has a 14-stage compressor and 4-stage turbine (2 high-pressure and 2 low pressure). The turbine shaft is coaxial with the compressor shaft and delivers power forward.

The helicopter had a cruise speed of 150 knots (173 miles per hour/278 kilometers per hour), and a maximum speed of 170 nautical miles per hour (196 miles per hour/315 kilometers per hour). The service ceiling was 20,400 feet (6,218 meters). Its range is 600 nautical miles (690 statute miles/1,111 kilometers), and it is capable of inflight refueling.

The Air Force ordered eight HH-53Bs, followed by 58 improved HH-53C Super Jolly Green Giants.¹ The first HH-53B, 66-14428, was delivered to the Air Force Air Rescue and Recovery Service at the Sikorsky plant in June 1967. It was flown to Eglin Air Force Base, Florida by Lieutenant Colonel James Dixon and Captain Fredric Donohue of Detachment 2, 37th Air Rescue and Recovery Squadron. For the next two months ARRS crews trained with it at Eglin.

Along with the second HH-53B, the new helicopter was then shipped to Vũng Tàu, Republic of Vietnam, aboard the former U.S. Navy escort carrier, USNS Card (T-AKV-40) for assignment to the 37th Aerospace Rescue and Recovery Squadron at Udorn Royal Thai Air Force Base. They were soon joined by four more HH-53Bs.

As upgraded HH-53Cs became available, the six -53Bs were returned to the United States, where some were used as trainers, and others as test aircraft for the development of the Pave Imp and Pave Low systems. 4428 was one of five HH-53Bs modified to the initial Pave Low configuration. This was followed by the HH-53H Pave Low II configuration.

In 1988, all HH-53 and CH-53 helicopters in the U.S. Air Force inventory began to be modified to the MH-53J Pave Low III Enhanced special operations configuration. The modifications, along with incorporation of a Service Life Extension Program (SLEP) were performed by Naval Air Rework Facility (NARF) at NAS Pensacola, Florida, or by the Marine Corps aviation depot at MCAS Cherry Point, North Carolina.

After nearly 40 years of service, 66-14428 was sent to The Boneyard at Davis-Monthan Air Force Base, Tucson, Arizona, 7 January 2007. By September 2008, all U.S. Air Force Pave Low helicopters had been withdrawn from service.
