Citation: He took part in a highly effective attack against vital oil installation in Ploesti, Rumania, on 9 July 1944. Just after “bombs away,” the plane received heavy and direct hits from antiaircraft fire. One crewmember was instantly killed and 6 others severely wounded. The airplane was badly damaged, two engines were knocked out, the control cables cut, the oxygen system on fire, and the bomb bay flooded with gas and hydraulic fluid. Regaining control of his crippled plane, 1st Lt. Pucket turned its direction over to the copilot. He calmed the crew, administered first aid, and surveyed the damage. Finding the bomb bay doors jammed, he used the hand crank to open them to allow the gas to escape. He jettisoned all guns and equipment but the plane continued to lose altitude rapidly. Realizing that it would be impossible to reach friendly territory he ordered the crew to abandon ship. Three of the crew, uncontrollable from fright or shock, would not leave. 1st Lt. Pucket urged the others to jump. Ignoring their entreaties to follow, he refused to abandon the 3 hysterical men and was last seen fighting to regain control of the plane. A few moments later the flaming bomber crashed on a mountainside. 1st Lt. Pucket, unhesitatingly and with supreme sacrifice, gave his life in his courageous attempt to save the lives of 3 others.
Donald Dale Pucket was born at Longmont, Colorado, 15 December 1915. He was the son of Roy A. Pucket, an automotive mechanic, and Lula M. (Gilmore?) Pucket.
Pucket attended the University of Colorado at Boulder where he studied business. He was president of the Board of Directors of the School of Business, and a member of the Delta Sigma Pi (ΔΣΠ) fraternity. During his senior year, he was the fraternity’s president and headmaster. Pucket graduated in 1938. Pucket was employed by a finance company as an insurance inspector.
On 16 September 1939, Donald Dale Pucket married Miss Lorene Edna Joyce, a public school teacher, at Denver, Colorado. They rented a home at 2705 High Street, Pueblo, Colorado.
In 1940, as required, Pucket registered for the Draft (conscription for military service). His registration shows that he was 5 feet, 8 inches (172.7 centimeters) tall and weighed 158 pounds (71.7 kilograms). He had brown hair and brown eyes.
Pucket enlisted as an aviation cadet in the United States Army Air Forces at Denver, Colorado, 25 November 1942 and was trained as a bomber pilot. He was commissioned a second lieutenant, U.S. Army Air Corps, in October 1943. Lieutenant Pucket was assigned to the 343rd Bombardment Squadron (Heavy), 98th Bombardment Group (Heavy), as a B-24 Liberator pilot and deployed to the Mediterranean Theater of Operations in April 1944. He was promoted to the rank of First Lieutenant in June 1944. He was killed in action during an attack against the oil refineries at Ploesti, Romania, 9 July 1944.
Lieutenant Pucket’s remains were eventually returned to the United States. On 31 October 1950, Lieutenant Pucket’s remains were interred in a group grave with those of five members of his crew, at the Jefferson Barracks National Cemetery, Lemay, Missouri. They were: Staff Sergeant Herschel K. Devore, Technical Sergeant Ilas B. Dye, Staff Sergeant Leon Fournas, Staff Sergeant Lawrence L. Hood and Staff Sergeant Jack C. Rathbun.
In addition to the Medal of Honor, First Lieutenant Donald Dale Pucket, United States Army Air Corps, was awarded the Distinguished Flying Cross, the Air Medal with 2 oak leaf clusters (three awards), and the Purple Heart.
[Note: Records available online do not indicate the specific variant or serial number of the B-24 Liberator flown by 1st Lieutenant Pucket, however research revealed that there were two B-24s lost by the 98th Bombardment Group on 9 July 1944. They were both North American/Dallas-built B-24G-15-NT Liberators, serial numbers 42-78346 and 42-78348. The B-24 in the photograph below is their sister ship, 42-78349.] ¹

3 July 1951: With his Chance Vought F4U-4B Corsair, Bu. No. 63056, hit and on fire, Captain James V. Wilkins, United States Marine Corps, of Marine Fighter Squadron 312 (VMF-312) stationed aboard USS Sicily (CVE-118), bailed out approximately 35 miles (56 kilometers) southeast of Wonson, North Korea. He parachuted onto a mountainside in the Anbyon Valley.
Severely burned and with an injured leg, Captain Wilkins was seen by North Korean soldiers along a heavily-traveled supply route. While enemy soldiers shot at him, Wilkins tried to escape by crawling up the mountainside.
Lieutenant (j.g.) John Kelvin Koelsch, United States Navy, was a helicopter pilot in charge of a detachment of Helicopter Utility Squadron Two (HU-2), stationed aboard a former U.S. Navy Landing Ship (Tank), USS LST-488. The LST had been transferred to Japan after World War II and converted to a merchant ship. During the Korean War, it and its 45-man Japanese crew were contracted to the U.S. Navy. The LST was reconverted to a helicopter support ship, designated Q-009.
A torpedo bomber pilot during World War II, Lieutenant Koelsch transferred to Helicopter Utility Squadron One (HU-1) at NAS Lakehurst, New Jersey, in 1949, and was trained to fly the Sikorsky HO3S-1 helicopter, a Navy variant of the commercial Sikorsky S-51. He had completed a combat tour aboard USS Princeton (CV-37) but rather than return to the United States with his squadron, requested a transfer to HU-2. Koelsch told his shipmates that he felt rescuing downed pilots was his mission.
When Captain Wilkins’ Corsair went down, Lieutenant Koelsch volunteered to attempt a rescue. Shortly before sunset, he and his rescue crewman, Aviation Machinist’s Mate 3rd Class George Milton Neal, boarded their helicopter, Sikorsky HO3S-1, Bu. No. 122715, and took off from Q-009 in a mist and low clouds.
Wilkins heard Koelsch’s helicopter approaching and moved back down the mountain toward his parachute. He saw the Sikorsky flying at about 50 feet (15 meters) below a layer of clouds. The helicopter was receiving heavy ground fire from the North Korean soldiers along the road. The Sikorsky was hit and Koelsch turned away, but he quickly returned. Koelsch located Wilkins and brought the HO3S-1 to a hover while rescue crewman Neal lowered a “horse collar” harness on a hoist cable. Neal then lifted the fighter pilot up to the helicopter.
The helicopter continued to be targeted by ground fire and it was finally shot down. 122715 crashed on the mountainside and rolled upside down. Koelsch and Neal were unhurt and Wilkins suffered no new injuries. Koelsch and Neal carried Wilkins and they moved away from the enemy forces, heading toward the coast. The three Americans evaded the enemy for nine days before they were captured.
John Koelsch refused to cooperate with his captors. He was held in isolation and subjected to torture. He soon became very ill. Just three months after being captured, Lieutenant (j.g.) John Kelvin Koelsch died. For his actions during and after 3 July 1951, he was awarded the Medal of Honor.
Captain Wilkins and AM3 Neal survived the war and were eventually returned to the United States. George Milton Neal was awarded the Navy Cross.
In 1965, the Garcia-class destroyer escort USS Koelsch (DE-1049, later classified as a frigate, FF-1049, in 1975) was christened in honor of the first helicopter pilot to be awarded the Medal of Honor.
John Kelvin Koelsch was born 22 December 1923 in the family home at 2 Draycott Place, Chelsea (a borough in the southwest part of London, England). He was the third son of Henry August Koelsch and Beulah Anne Hubbard Koelsch. Mr. Koelsch was an American banker. The family returned to America aboard White Star liner R.M.S. Adriatic, sailing from Liverpool on 26 April 1954, and arriving at the Port of New York on 5 May.
In America, the Koelsch family lived in Briarcliff Manor, Westchester County, New York.
John K. Koelsch enlisted as an aviation cadet in the United States Navy 14 September 1942. He was trained as a pilot. When qualified as a Naval Aviator, Koelsch was commissioned as an ensign, 16 October 1944. He was promoted to the rank of lieutenant (junior grade) 1 August 1946.
Following the Korean Armistice Agreement, Lieutenant Koelsch’s remains were returned to the United States and interred at Arlington National Cemetery, 14 October 1955.

For conspicuous gallantry and intrepidity in action at the risk of life above and beyond the call of duty, 23 June 1944 near Ploesti, Rumania, while flying as bombardier of a B17 type aircraft.
On the bomb run 2d Lt. Kingsley’s aircraft was severely damaged by intense flak and forced to drop out of formation but the pilot proceeded over the target and 2d Lt. Kingsley successfully dropped his bombs, causing severe damage to vital installations. The damaged aircraft, forced to lose altitude and to lag behind the formation, was aggressively attacked by 3 ME-109 aircraft, causing more damage to the aircraft and severely wounding the tail gunner in the upper arm. The radio operator and engineer notified 2d Lt. Kingsley that the tail gunner had been wounded and that assistance was needed to check the bleeding. 2d Lt. Kingsley made his way back to the radio room, skillfully applied first aid to the wound, and succeeded in checking the bleeding. The tail gunner’s parachute harness and heavy clothes were removed and he was covered with blankets, making him as comfortable as possible. Eight ME-109 aircraft again aggressively attacked 2d Lt. Kingsley’s aircraft and the ball turret gunner was wounded by 20mm. shell fragments. He went forward to the radio room to have 2d Lt. Kingsley administer first aid. A few minutes later when the pilot gave the order to prepare to bail out, 2d Lt. Kingsley immediately began to assist the wounded gunners in putting on their parachute harness. In the confusion the tail gunner’s harness, believed to have been damaged, could not be located in the bundle of blankets and flying clothes which had been removed from the wounded men. With utter disregard for his own means of escape, 2d Lt. Kingsley unhesitatingly removed his parachute harness and adjusted it to the wounded tail gunner. Due to the extensive damage caused by the accurate and concentrated 20mm. fire by the enemy aircraft the pilot gave the order to bail out, as it appeared that the aircraft would disintegrate at any moment. 2d Lt. Kingsley aided the wounded men in bailing out and when last seen by the crewmembers he was standing on the bomb bay catwalk. The aircraft continued to fly on automatic pilot for a short distance, then crashed and burned. His body was later found in the wreckage. 2d Lt. Kingsley by his gallant heroic action was directly responsible for saving the life of the wounded gunner.
David Richard Kingsley was born 27 June 1918 at Portland, Oregon. He was the second of nine children of David Ross Kingsley, a machinist, and Angelina Marie Rutto Kingsley. He attended St. Michael’s School in Portland.
With both of their parents dead and their oldest brother in the Navy, Dave Kingsley cared for his younger siblings. He worked as a firefighter, and was engaged to Miss Harriet Zalabak.
Kingsley enlisted in the United States Army Air Forces at Portland Army Air Base, 14 April 1942. He had brown hair, blue eyes, was 5 feet, 10 inches (1.78 meters) tall and weighed 165 pounds (75 kilograms). Kingsley was trained as a bombardier and commissioned a second lieutenant in July 1943.
The gunner saved by Kingsley later said, “David then took me in his arms and struggled to the bomb bay, where he told me to keep my hand on the rip cord and said to pull it when I was clear of the ship. . . Then he told me to bail out. I watched the ground go by for a few seconds and then I jumped. I looked at Dave the look he had on his face was firm and solemn. He must have known what was coming because there was no fear in his eyes at all. That was the last time I saw. . . Dave standing in the bomb bay.”
Kingsley’s bomber, a Vega-built B-17F-35-VE, 42-5951, crashed near the village of Suhozem, in central Bulgaria. In addition of Kingsley, seven people on the ground were killed.
Major General Ralph P. Cousins presented Lieutenant Kingley’s Medal of Honor to his older brother, Pharmacist’s Mate First Class Thomas Kingsley, U.S. Navy, in a ceremony held at St. Michael the Archangel Church, Portland, Oregon, 4 May 1945.
Following the war, Lieutenant Kingley’s remains were exhumed and returned to the United States. They were then buried at the Arlington National Cemetery, Arlington, Virginia.
Kingsley Air National Guard Base, Klamath Falls, Oregon, is named in his honor.
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.
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.
For his actions on 19 June 1968, Lieutenant Clyde Everett Lassen was awarded the Medal of Honor. Lieutenant (j.g.) LeRoy Cook received the Navy Cross. AE2 Bruce Dallas and AE3 Don West each received the Silver Star.
Clementine Two was a Kaman SH-2A Seasprite, Bu. No. 149764 (c/n 66). The SH-2A is 52 feet, 2.2 inches (15.905 meters) long with rotors turning, with an overall height of 14 feet, 8.6 inches (4.486 meters). The four-bladed main rotor has a diameter of 44 feet, 0 inches (13.411 meters) and rotates counter-clockwise, as seen from above (the advanicng blade is on the helicopter’s right). The blades are controlled by Kaman’s unique servo flap system. The three-bladed tail rotor is mounted on the left side of a pylon and rotates clockwise, as seen from the helicopter’s left (The advancing blade is below the axis of rotation). The helicopter’s main landing gear was retractable. The SH-2A has and empty weight is 6,110 pounds (2,771 kilograms) and maximum takeoff weight is 10,000 pounds (4,536 kilograms).
The SH-2A is powered by a single General Electric T58-GE-8B turbine engine. The T58 is a free power turboshaft, with a 10-stage axial-flow compressor section, an annular combustion chamber with 16 burner nozzles, and a 3-stage turbine (2 gas-generator stages and a single power-turbine stage). The T58-GE-8B has a Normal Power rating of 1,050 shaft horsepower at 19,500 r.p.m. at Sea Level, and Military Power rating of 1,250 shaft horsepower at 19,500 r.p.m. The engine is 1 foot, 8.9 inches (0.531 meters) in diameter, 4 feet, 11.0 inches (1.499 meters) long, and weighs 305 pounds (138 kilograms).
The SH-2A Seasprite has a Hover Ceiling Out of Ground Effect (HOGE) of 4,600 feet (1,402 meters). With a crew of four, the hover ceiling is reduced to 2,800 feet (853 meters). Its service ceiling is 15,000 feet (4,572 meters).
The SH-2A has a cruise speed of 125 knots (144 miles per hour/232 kilometers per hour) and a maximum speed of 140 knots (161 miles per hour/259 kilometers per hour) at Sea Level. Its combat radius is 125 nautical miles (144 miles/232 kilometers). The maximum range is 465 nautical miles (535 miles/861 kilometers).
Clementine 2 was armed with two M60 7.62 mm machine guns.
88 UH-2As were built 1959-1960, before production shifted to a twin-engine variant.
Seasprite 149764 was lost in the South China Sea, 7 January 1969.
Clyde Everett Lassen was born at Fort Myers, Florida, 14 March 1942. He graduated from Venice High School, Englewood, Florida, in 1960.
Lassen enlisted in the United States Navy, 14 September 1961. He served as an Aviation Electronics Technician, 3rd Class (AT3). In 1964, he was accepted as a Naval Aviation Cadet at NAS Pensacola. On completion of flight training, Lassen was commissioned an ensign and awarded the wings of a Naval Aviator.
Ensign Lassen married Miss Linda Barbara Sawn in October 1965.
He was promoted to lieutenant (junior grade), 16 December 1966, and to lieutenant, 1 July 1968.
President Lyndon Johnson presented the Medal of Honor to Lieutenant Lassen at a ceremony at The White House, 16 January 1969.
Lieutenant Lassen was promoted to the rank of lieutenant commander 1 August 1972, and to commander, 1 July 1975. Commander Lassen retired from the U.S. Navy in December 1982.
Commander Lassen donated his Medal of Honor to the National Naval Aviation Museum 19 June 1993.

25 May 1927: At Wright Field, now Wright-Patterson Air Force Base, Dayton, Ohio, First Lieutenant James H. “Jimmy” Doolittle, United States Army Air Corps, was the first pilot to successfully perform an outside loop.
Flying a Curtiss P-1B Hawk pursuit, he began the maneuver in level flight at 10,000 feet (3,048 meters), then pushed the nose down into a dive. When he reached 280 miles per hour (450 kilometers per hour), Doolittle continued to pitch the nose “down” and the airplane flew through a complete vertical circle, with the pilot’s head to the outside of the loop.
Jimmy Doolittle attempted to repeat the outside loop at the 1929 Cleveland National Air Races, with a Curtiss P-1C Hawk, serial number 29-227. The airplane’s wings came off but Doolittle parachuted to safety. (The Curtiss P-1C used wing radiators instead of the large radiator under the nose of the P-1B. This substantially reduced the aerodynamic drag which allowed the airplane to accelerate to too high an airspeed during Doolittle’s maneuver.)
Jimmy Doolittle was one of America’s foremost pioneering aviators. He set many records, won air races, tested and developed new flying equipment and techniques. He was a highly-educated military officer, having earned his Bachelor of Arts from the University of California Berkeley School of Mines, and M.S and D.Sc. degrees in Aeronautical Engineering from the Massachusetts Institute of Technology. As a pioneer aviator, he won every international air race, and had been awarded every international aviation trophy. He was also the first pilot to fly completely by reference to instruments.
During the early days of America’s involvement in World War II, Lieutenant Colonel Doolittle planned and led the Halsey-Doolittle B-25 raid on Japan. He was awarded the Medal of Honor and promoted to brigadier general, and then placed in command of the Twelfth Air Force in North Africa. As a major general, he commanded the Fifteenth Air Force in the Mediterranean Theater of Operations. Lieutenant General Doolittle commanded the Eighth Air Force in England from January 1944 to September 1945. He supervised the transition of the 8th to the Boeing B-29 Superfortress and its eventual transfer to bases on Okinawa to continue the war against Japan. World War II came to an end before any of the 8th’s B-29s actually moved west.
After the war, Lieutenant General Doolittle was placed on the inactive list. On 4 April 1985, by Act of Congress, James H. Doolittle was promoted to General, United States Air Force, Retired.
General James Harold Doolittle is the only person to be awarded both the Medal of Honor and the Medal of Freedom. He died 27 September 1993 at the age of 96 years. He was buried at the Arlington National Cemetery, Arlington, Virginia.
The Curtiss P-1B Hawk was a single-engine, single-seat, single-bay biplane pursuit, an aircraft type now known as a fighter. The airplane and its D-12 Conqueror engine were both built by the Curtiss Aeroplane and Motor Co., Garden City, New York.
The P-1B was 22 feet, 10 inches (6.960 meters) long with an upper wingspan of 31 feet, 6 inches (9.601 meters). The lower wing had a span of 26 feet, 0 inches (7.925 meters), a narrower chord, and was staggered 3 feet, 2½ inches (0.978 meters) behind the upper. Both wings had significant taper with rounded tips. Their angle of incidence was 0°. The upper wing had no dihedral, while the inboard lower wing had 1°, and the outer, 5°. The total wing area was 252 square feet (23.4 square meters). The horizontal stabilizer span was 10 feet, 6.0 inches (3.200 meters) and its incidence could be adjusted from +3° to -1.5°. The vertical fin was offset 2° left of the airplane’s centerline. The overall height of the airplane was 8 feet, 10 inches (2.712 meters).
The P-1B had an empty weight of 2,105 pounds (955 kilograms), gross weight of 2,932 pounds (1,330 kilograms), and maximum weight of 3,562 pounds ( kilograms).
The P-1B was powered by a liquid-cooled, normally-aspirated, 1,145.1-cubic-inch-displacement (18.8 liter) Curtiss D-12D (V-1150-3) dual overhead cam (DOHC) 4-valve 60° V-12 engine with a compression ratio of 5.7:1. It was a direct-drive engine, rated at 415 horsepower at 2,000 r.p.m. at Sea Level, and 460 horsepower at 2,300 r.p.m. The D-12 was 58¾ inches (1.492 meters) long, 34¾ inches (0.883 meters) high and 28¼ inches (0.718 meters) wide. It weighed 680 pounds (308 kilograms). The P-1B was equipped with an aluminum Curtiss-Reed propeller with a diameter of 8 feet, 9 inches (2.667 meters).
The pursuit had a cruise speed of 127 miles per hour (204 kilometers per hour). Its maximum speed was 159.6 miles per hour (256.9 kilometers per hour) at Sea Level, and 157 miles per hour (253 kilometers per hour) at 5,000 feet (1,524 meters). It had a service ceiling of 21,400 feet (6,523 meters) and absolute ceiling of 22,900 feet (6,980 meters). Its range was 342 miles (550 kilometers).
The P-1B was armed with two fixed air-cooled Browning machine guns, one .50-caliber and one .30-caliber.
The Air Corps ordered 93 Curtiss P-1 Hawks between 1925 and 1929.
