29 October 1953: Lieutenant Colonel Frank Kendall (“Pete”) Everest, United States Air Force, flew a new prototype air superiority fighter, North American Aviation’s YF-100A Super Sabre, serial number 52-5754, over the 3 kilometer and 15 kilometer courses at the Salton Sea, in the Colorado Desert of southeastern California.

Flying four runs over the short course, Everest averaged 757.75 miles per hour (1,219.48 kilometers per hour). Although this was 4.80 miles per hour (7.725 kilometers per hour) faster than the FAI record set three weeks earlier by Lieutenant Commander James B. Verdin, U.S. Navy, with a Douglas XA4D-1 Skyray,¹ it was not fast enough to establish a new world record under FAI rules, which required that a new record exceed the previous record by 1%.

Next came four speed runs over the 15-to-25 kilometer course. All runs were made with the Super Sabre flying within 100 feet (30 meters) of the ground. The official Fédération Aéronautique Internationale (FAI) average speed was 1,215.298 kilometers per hour (755.151 miles per hour)—0.99 Mach. ²

The course at the Salton Sea was used because its surface lies 235 feet (72 meters) below Sea Level. The denser air causes undesired transonic effects to occur at lower speeds, but the higher air temperatures help to delay them, allowing the pilot a greater margin of control during the speed record runs.

Frank Kendall (“Pete”) Everest, Jr., was born 10 Aug 1920, at Fairmont, Marion County, West Virginia. He was the first of two children of Frank Kendall Everest, an electrical contractor, and Phyllis Gail Walker Everest. Attended Fairmont Senior High School, Fairmont, West Virginia, graduating in 1939. He studied at Fairmont State Teachers College, also in Fairmont, West Virginia, and then studied engineering at the University of West Virginia in Morgantown.

Pete Everest enlisted as an aviation cadet in the United States Army Air Corps at Fort Hayes, Columbus, Ohio, 7 November 1941, shortly before the United States entered World War II. His enlistment records indicate that he was 5 feet, 7 inches (1.703 meters) tall and weighed 132 pounds (59.9 kilograms). He graduated from pilot training and was commissioned as a second lieutenant, Air Reserve, 3 July 1942.

2nd Lieutenant Everest married Miss Avis June Mason in Marion, West Virginia, 8 July 1942. they would have three children.

He was promoted to 1st Lieutenant, Army of the United States, 11 November 1942. He was assigned as a Curtiss-Wright P-40 Warhawk pilot, flying 94 combat missions in North Africa, Sicily and Italy. He was credited with shooting down two German airplanes and damaging a third. Everest was promoted to the rank of Captain, 17 August 1943.

In 1944, Everest was returned to the United States to serve as a flight instructor. He requested a return to combat and was then sent to the China-Burma-India theater of operations where he flew 67 missions and shot down four Japanese airplanes. Everest was appointed commanding officer of the 29th Fighter Squadron (Provisional), 5th Fighter Group (Provisional) at Chihkiang, China, in April 1945. He was himself shot down by ground fire in May 1945. Everest was captured by the Japanese and suffered torture and inhumane conditions before being freed at the end of the war. He was promoted to the rank of major, 1 July 1945. He was returned to the United States military 3 October 1945.

Following World War II, Major Everest was assigned as a test pilot at Wright-Patterson Air Force Base, Ohio, before going west to the Air Force Flight Test Center at Edwards Air Force Base, California.

Major Everest was returned to the permanent rank of first lieutenant, Air Corps, 19 June 1947, with date of rank retroactive to 3 July 1945.

At Edwards, Pete Everest was involved in nearly every flight test program, flying the F-88, F-92, F-100, F-101, F-102, F-104 and F-105 fighters, the XB-51, YB-52, B-57 and B-66 bombers. He also flew the pure research aircraft, the “X planes:” the X-1, X-1B, X-2, X-3, X-4 and X-5. Pete Everest flew the X-1B to Mach 2.3, and he set a world speed record with the X-2 at Mach 2.9 (1,957 miles per hour, 3,149.5 kilometers per hour) which earned him the title, “The Fastest Man Alive.” He was the test pilot on thirteen of the twenty X-2 flights.

In 1957, Lieutenant Colonel Everest was awarded the Harmon Trophy “for the most outstanding international achievements in the arts and/or science of aeronautics for the preceding year,” and also received the Octave Chanute Award “for an outstanding contribution made by a pilot to the art, science and technology of aeronautics.”

Frank Everest returned to operational assignments and commanded a fighter squadron, two combat crew training wings, and was assigned staff positions at the Pentagon. On 20 November 1963, Colonel Everest, commanding the 4453rd Combat Crew Training Squadron, flew one of the first two operational McDonnell F-4C Phantom II fighters from the factory in St. Louis, Missouri, to MacDill Air Force Base, Tampa, Florida.

In 1965, Pete Everest was promoted to the rank of brigadier general. He was assigned as commander of the Aerospace Rescue and Recovery Service. General Everest retired from the Air Force in 1973 after 33 years of service.

Shortly after he retired from the Air Force, on 5 April 1973, Sikorsky Aircraft appointed General Everest its Chief Test Pilot. The manufacturer was developing the S-70 Black Hawk and S-76 commercial helicopters at the time.

During his military career General Everest was awarded the Air Force Distinguished Service Medal; Legion of Merit with two oak leaf clusters (three awards); Distinguished Flying Cross with two oak leaf clusters (three awards); Purple Heart; Air Medal with one silver and two bronze oak leaf clusters (seven awards); Air Force Commendation Medal with one oak leaf cluster (two awards); Presidential Unit Citation with two bronze oak leaf clusters (three awards); Air Force Gallant Unit Citation; Prisoner of War Medal; American Campaign Medal; European-African-Middle Eastern Campaign medal with four bronze stars; Asiatic-Pacific Campaign Medal with two bronze stars; World War II Victory Medal; National Defense Service Medal; Armed Forces Expeditionary Medal; Vietnam Service Medal; Air Force Longevity Service Award with one silver and two bronze oak leaf clusters (seven awards); Air Force Small Arms Expert Marksmanship Ribbon; and the Republic of Vietnam Campaign Medal with 1960– device. General Everest was rated as a Command Pilot, and a Basic Parachutist.

The North American Aviation F-100 Super Sabre was designed as a supersonic day fighter. Initially intended as an improved F-86D and F-86E, the “Sabre 45” soon developed into an almost completely new airplane.

The Super Sabre had a 49° 2′ sweep to the leading edges of the wings and horizontal stabilizer. The total wing area was 385.2 square feet (35.79 square meters). The wings had an angle of incidence of 0°, with no twist or dihedral. The ailerons were placed inboard on the wings and there were no flaps, resulting in a high stall speed in landing configuration. The horizontal stabilizer was moved to the bottom of the fuselage to keep it out of the turbulence created by the wings at high angles of attack. The F-100A had a distinctively shorter vertical fin than the YF-100A. The upper segment of the vertical fin was swept 49° 43′.

There were two service test prototypes, designated YF-100A, followed by the production F-100A series. The first ten production aircraft (all of the Block 1 variants) were used in the flight testing program.

The F-100A Super Sabre was 47 feet, 1¼ inches (14.357 meters) long with a wingspan of 36 feet, 6 inches (11.125 meters). With the shorter vertical fin, the initial F-100As had an overall height of 13 feet, 4 inches (4.064 meters), 11 inches (27.9 centimeters) less than the YF-100A.

The F-100A had an empty weight of 18,135 pounds (8,226 kilograms), and its maximum takeoff weight was 28,971 pounds (13,141 kilograms). It had an internal fuel capacity of 744 gallons (2,816 liters) and could carry two 275 gallon (1,041 liter) external fuel tanks.

The new air superiority fighter was powered by a Pratt & Whitney Turbo Wasp J57-P-7 engine. The J57 was a two-spool axial-flow turbojet which had a 16-stage compressor section (9 low- and 7 high-pressure stages) and a 3-stage turbine (2 high- and 1 low-pressure stages). Its continuous power rating was 8,000 pounds of thrust (35.586 kilonewtons). The Military Power rating was 9,700 pounds (43.148 kilonewtons) (30-minute limit). Maximum power was 14,800 pounds (43.148 kilonewtons) with afterburner (5-minute limit). The engine was 20 feet, 9.7 inches (6.342 meters) long, 3 feet, 3.9 inches (1.014 meters) in diameter, and weighed 5,075 pounds (2,303 kilograms). Later production aircraft used a J57-P-39 engine, which had the same ratings.

The Super Sabre was the first U.S. Air Force fighter capable of supersonic speed in level flight.

The YF-100A had a maximum speed of 660 miles per hour (1,062 kilometers per hour) at 43,350 feet (13,213 meters). During testing, 52-5754 reached Mach 1.44 in a dive. The service ceiling was 52,600 feet (16,033 meters). Range with internal fuel was 422 miles (679 kilometers).

The production F-100 was armed with four M39 20 mm autocannons, capable of firing at a rate of 1,500 rounds per minute. The ammunition capacity of the F-100 was 200 rounds per gun.

North American Aviation built 199 F-100A Super Sabres at its Inglewood, California, plant before production shifted to the F-100C fighter bomber variant. Approximately 25% of all F-100As were lost in accidents.

28 October 1952: The prototype Douglas XA3D-1 Skywarrior, Bu. No. 125412, made its first flight at Edwards Air Force Base, California. Douglas test pilot George R. Jansen was in the cockpit.

The Skywarrior was a carrier-based, twin-engine, swept-wing strategic bomber, designed to carry a 12,000 pound (5,443 kilogram) bomb load. The prototype was equipped with two Westinghouse XJ40-WE-12 turbojet engines producing 7,000 pounds of thrust (31.138 kilonewtons), each.

Designed to be launched from an aircraft carrier, fly 2,000 miles (3,219 kilometers), deliver a 3.8 megaton Mark 15 thermonuclear bomb on target, then return to the carrier, the Skywarrior was a considerable challenge for its designers. It was operated by a three man crew: pilot, navigator/bombardier and gunner.

The production A3D-1 was 74 feet, 5 inches (22.682 meters) long with a wingspan of 72 feet, 6 inches (22.098 meters) and overall height of 22 feet, 10 inches (6.960 meters). The shoulder-mounted wings were swept back at a 36° angle and the wings and vertical fin were hinged so that they could be folded for storage aboard the aircraft carrier. The bomber’s empty weight was 35,900 pounds (16,284 kilograms) and the maximum takeoff weight was 70,000 pounds (31,752 kilograms).

When the two prototypes’ Westinghouse JX40 engines proved to be underpowered, they were replaced with Pratt & Whitney J57-P-1 turbojets, rated at 9,000 pounds of thrust (40.034 kilonewtons). The J57 was a two-spool axial-flow turbojet which had a 16-stage compressor section and a 3-stage turbine. (Both had high- and low-pressure stages.) The engine was 15 feet, 3.5 inches (4.661 meters) long, 3 feet, 5.0 inches (1.041 meters) in diameter, and weighed 4,390 pounds (1,991 kilograms). Production models were equipped with the J57-P-6, rated at 9,700 pounds of thrust (43.148 kilonewtons).

The A3D-1 had a cruise speed of 519 miles per hour (835 kilometers per hour) and maximum speed of 621 miles per hour (999 kilometers per hour) at 1,000 feet (305 meters). The combat ceiling was 40,500 feet (12,344 meters). It had a range of 2,100 miles (3,380 kilometers). The combat radius was 1,150 miles (1,851 kilometers).

The Skywarrior could carry 12,000 pounds (5,443 kilograms) of conventional or Special Weapons (MK 43 or MK 57 nuclear bombs) in its internal bomb bay. A remotely-operated turret in the tail was armed with two An-M3 20 mm cannon with 500 rounds per gun.

The first A3D-1 production aircraft were painted a glossy sea blue. This was soon changed to a flat light gray for the sides and upper surfaces with gloss white underneath. This provided better camouflage as well as thermal protection from nuclear blast.

Douglas built 282 A3D Skywarriors between 1956 and 1961. They remained in service as late as 1991. The U.S. Air Force ordered 294 B-66 Destroyer medium bombers, which were developed from the A3D. The first XA3D-1, Bu. No. 125412, was used as a ground trainer after the test flight program was completed.

George R. Jansen was the Director of Flight Operations for the Douglas Aircraft Company. He had been a bomber pilot flying the B-24 Liberator during World War II. After one mission, his bomber, Margaret Ann, returned to base in England with more than 750 bullet and shrapnel holes, and one crewman dead and another wounded. He twice flew missions from North Africa against the refineries at Ploesti, Romania. At the age of 22, Jansen was a major in command of the 68th Bombardment Squadron (Heavy), 44th Bombardment Group (Heavy). He had been awarded three Distinguished Flying Crosses and five Air Medals.

After the war, George Jansen went to work for Douglas as a production test pilot. He graduated from the Air Force Test Pilot School at Edwards Air Force Base in 1952. He flew many of Douglas’s new prototype aircraft, and also flew the modified Boeing P2B-1S Superfortress mother ship to carry the D-558-II Skyrocket to altitude. He made many of the first flights for Douglas, both military and civil. He passed away at the age of 70 years.

27 October 2015: The first flight of the Sikorsky CH-53K King Stallion Engineering Development Model–1, Bu. No. 169019, at West Palm Beach, Florida. In the cockpit was Stephen McCulley, Chief Experimental Test Pilot for Sikorsky. During the 30 minute flight, the new helicopter demonstrated sideward, rearward and forward flight while remaining in in-ground-effect hover.

Up to this point, the helicopter had completed about 200 hours of “turn-time,” or ground testing, with engines running..

Three more aircraft will join the test fleet for a planned 2,000 hour flight test program.

The fuselage of the CH-53K King Stallion is 73 feet, 1.5 inches (22.289 meters) long and its width is 9 feet, 10 inches (2.997 meters). The maximum width, across the sponsons, is 17 feet, 6 inches (5.334 meters). The seven-bladed main rotor has a diameter of 79 feet (24.079 meters). The four-blade tail rotor is 20 feet (6.096 meters) in diameter. The tail rotor is tilted 20° to the left. With rotors turning, the helicopter has an overall length of 99 feet (30.175 meters), and height of 28 feet, 4.9 inches (8.659 meters). The helicopter’s maximum gross weight is 88,000 pounds (39,916 kilograms).

Power is supplied by three General Electric T408-GE-400 engines which produce 7,500 shaft horsepower, each. The engine has digital electronic controls. The T408 has a 6-stage compressor section (5 axial-flow stages, 1 centrifugal-flow stage) and 5 stage turbine section (2 high- and 3 low-pressure stages). The engine is 57.5 inches (1.461 meters) long and 27 inches (0.686 meters) in diameters.

At Sea Level with maximum continuous power, the CH-53K cruises at 158 knots (182 miles per hour/293 kilometers per hour). It can hover out of ground effect at Sea Level at its maximum gross weight. The helicopter’s service ceiling is 16,000 feet (4,877 meters).

The first production CH-53K was delivered to the U.S. Marine Corps on 16 May 2018, at West Palm Beach, Florida.

October 27, 1954: Between August 1954 and May 1956, Joseph A. Walker, the National Advisory Committee for Aeronautics’ chief project test pilot for the Douglas X-3 supersonic research aircraft, made twenty research flights in the “Stiletto.”

On the tenth flight, 27 October, Walker took the X-3 to an altitude of 30,000 feet (9,144 meters). With the rudder centered, he put the X-3 into abrupt left aileron rolls, first at 0.92 Mach and then at Mach 1.05. Both times, the aircraft violently yawed to the right and then pitched down. Walker was able to recover before the X-3 was completely out of control.

This was a new and little understood condition called inertial roll coupling. It was a result of the aircraft’s mass being concentrated within its fuselage, the gyroscopic effect of the turbojet engines and the inability of the wings and control surfaces to stabilize the airplane and overcome its rolling tendency. (Just two weeks earlier, North American Aviation’s Chief Test Pilot George S. Welch had been killed when the F-100A Super Sabre that he was testing also encountered inertial roll coupling and disintegrated.)

A post-flight inspection found that the X-3 had reached its maximum design load. The airplane was grounded for the next 11 months.

The Douglas X-3, serial number 49-2892, was built for the Air Force and NACA to explore flight in the Mach 1 to Mach 2 range. It was radically shaped, with a needle-sharp nose, very long thin fuselage and small straight wings. Two X-3 aircraft had been ordered from Douglas, but only one completed.

The X-3 was 66 feet, 9 inches (20.345 meters) long, with a wing span of just 22 feet, 8.25 inches (6.915 meters). The overall height was 12 feet, 6.3 inches (3.818 meters). The X-3 had an empty weight of 16,120 pounds (7,312 kilograms) and maximum takeoff weight of 23,840 pounds (10,814 kilograms).

It was to have been powered by two Westinghouse J46 engines, but when those were unsatisfactory, two Westinghouse XJ34-WE-17 engines were substituted. This was an axial flow turbojet with an 11-stage compressor and 2-stage turbine. It was rated at 3,370 pounds (14.99 kilonewtons) of thrust, and 4,900 pounds (21.80 kilonewtons) with afterburner. The XJ34-WE-17 was 14 feet, 9.0 inches (4.496 meters) long, 2 feet, 1.0 inch (0.635 meters) in diameter and weighed 1,698 pounds (770 kilograms).

The X-3 had a maximum speed of 706 miles per hour (1,136 kilometers per hour) and a service ceiling of 38,000 feet (11,582 meters).

The X-3 was very underpowered with the J37 engines, and could just reach Mach 1 in a shallow dive. The X-3′s highest speed, Mach 1.208, required a 30° dive. It was therefore never able to be used in flight testing the supersonic speed range for which it was designed. Because of its design characteristics, though, it was very useful in exploring stability and control in the transonic range.

At one point, replacing the X-3’s turbojet engines with two Reaction Motors XLR-11 rocket engines was considered. Predictions were that a rocket-powered X-3 could reach Mach 4.2. However, with Mach 2 Lockheed F-104 becoming operational and North American Aviation’s X-15 hypersonic research rocketplane under construction, the idea was dropped. Technology had passed the X-3 by.

In addition to Douglas Aircraft test pilot Bill Bridgeman, the Douglas X-3 was flown by Air Force test pilots Lieutenant Colonel Frank Everest and Major Chuck Yeager and  NACA pilot Joe Walker.

Joe Walker resumed flight testing the X-3 in 1955. Its final flight was 23 May 1956. After the flight test program came to an end, the X-3 was turned over to the National Museum of the United States Air Force, Wright-Patterson Air Force Base, Ohio.

Citation:
Distinguished Service Cross

The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to First Lieutenant (Air Service) Russell L. Maughan, United States Army Air Service, for extraordinary heroism in action while serving with 138th Aero Squadron, U.S. Army Air Service, A.E.F., near Sommerance, France, 27 October 1918. Accompanied by two other planes, Lieutenant Maughan was patrolling our lines, when he saw slightly below him an enemy plane (Fokker type). When he started an attack upon it he was attacked from behind by four more of the enemy. By several well-directed shots he sent one of his opponents to the earth, and, although the forces of the enemy were again increased by seven planes, he so skillfully maneuvered that he was able to escape toward his lines. While returning he attacked and brought down an enemy plane which was diving on our trenches.

Maughan is credited with four enemy aircraft destroyed while flying a SPAD S.XIII C.I fighter.

Russell Lowell Maughan was born at Logan, Utah, 28 March 1893. He was the sixth of eight children of Peter Weston Maughan, an accountant, and Mary Lucinda Naef Maughan. He attended Utah Agricultural College in Logan and graduated with a bachelor of science degree in 1917.

Maughan was commissioned as a second lieutenant in the U.S. Army Signal Officers Reserve Corps, 28 May 1917. He was promoted to first lieutenant, 8 January 1918. This commission was vacated 10 September 1920 and he was appointed a first lieutenant, Air Service, United States Army, retroactive to 1 July 1920.

On 14 August 1919, Maughan married Miss Ila May Fisher at Logan, Utah. They would have three children, but divorced sometime after 1940. His son, Russell L. Maughan, Jr., would become an cadet at the United States Military Academy (West Point) and be commissioned as an officer in the U.S. Air Force.

Following the War, Lieutenant Maughan became a test pilot at McCook Field, Ohio. In 1921, he was reassigned to the 91st Observation Squadron, based at the Presidio of San Francisco.

On 14 October 1922, Rusell Maughan won the Pulitzer Trophy Race at Selfridge Field, near Mount Clemens, Michigan, before a crowd of 200,000 spectators. He set two World Speed Record during the race with his Curtiss R-6: 330.41 kilometers per hour (205.31 miles per hour) over a distance of 100 kilometers,¹ and 331.46 kilometers per hour (205.96 miles per hour) over a distance of 200 kilometers).² On 29 March 1923, he set another World Speed Record, 380.75 kilometers per hour (236.587 miles per hour),³ again flying a Curtiss R-6.

On 23 June 1924, Lieutenant Maughan flew a Curtiss PW-8 Hawk from Mitchel Field, Long Island, New York, to the Presidio of San Francisco on the west coast of California, in an elapsed time of 21 hours, 47 minutes including refueling stops enroute. This was the “Dawn-to-Dusk Flight.” For this transcontinental flight, Maughan was awarded the Distinguished Flying Cross.

On 1 October 1930, Maughan was promoted to captain. He served in the Philippine Islands from 1930 to 1935, acting as an advisor to the government until 1932. From 1932 to 1935, he served as the post operations officer. He and his family lived in Manila. They returned to the United States aboard SS Columbus, a Norddeutscher Lloyd passenger liner, arriving at New York City from Southampton, 18 August 1935.

Captain Maughan served as an aviation advisor to the governor general of the Philippine Islands, from 1935 to 1939. On 16 June 1936, Captain Maughan was promoted to major (temporary). That rank was made permanent 12 June 1939. He was promoted to lieutenant colonel, 11 March 1940. Just prior to World War II, Lieutenant Colonel Maughan was sent on a survey tour to identify suitable locations for airfields in Greenland.

During World War II, Lieutenant Colonel Maughan commanded the 60th Troop Carrier Group, a Douglas C-47 unit, 1941–42, and then, with the rank of colonel, he commanded the 51st Troop Carrier Wing during Operation Torch, the Allied invasion of North Africa.

On 25 October 1946, Colonel Maughan married Lois Rae Roylance at Las Vegas, Nevada. She was 21 years his junior. They lived in Portland, Oregon.

Colonel Maughan later commanded Lemoore Army Airfield, California, and Portland Air Force Base, Oregon.

Maughan was discharged from the U.S. Air Force, 30 November 1947, at the U.S. Army Hospital at Valley Forge, Pennsylvania. He died at the U.S. Air Force Hospital, Lackland Air Force Base, San Antonio, Texas, 21 April 1958, at the age of 65 years. He was buried at the Logan City Cemetery, Logan, Utah.

SPAD S.XIII at Air Service Production Center No. 2, Romorantin Aerodrome, France, 1918. (U.S. Air Force)

The Société Pour L’Aviation et ses Dérivés SPAD S.XIII C.1 was a single-seat, single-engine, two-bay biplane designed by Technical Director Louis Béchéreau. The chasseur was first flown by René Pierre Marie Dorme, 4 April 1917. It was constructed of a wooden framework and covered with doped fabric. Sheet metal panels covered the engine and cockpit.

The SPAD S.XIII was 20 feet, 4 inches (6.198 meters) long with the wings having an equal span of 26 feet, 3¾ inches (8.020 meters). It had an overall height of 7 feet, 6½ inches (2.299 meters). The total wing area was 227 square feet (21.089 square meters). The wings each had a chord of 4 feet, 7-1/8 inches (1.400 meters) with 0° dihedral and 1¼° stagger. The vertical gap between the upper and lower wings was 3 feet, 10½ inches (1.181 meters). The upper wing had a 1½° angle of incidence; the lower wing had 1° angle of incidence. There were ailerons on the upper wing only. They had a span of 7 feet, 3½ inches (2.222 meters) and chord of 1 foot, 7½ inches (0.495 meters). The horizontal stabilizer span was 10 feet, 2 inches (3,099 meters. Its maximum chord was 1 foot, 8¾ inches (0.527 meters). The vertical fin height was 2 feet, 7/8-inch (0.876 meters) and it was 3 feet, 11¼ inches (1.200 meters) long at the base. The rudder was 3 feet, 10-5/8 inches (1.184 meters) high with a maximum chord of 2 feet, 2 inches (0.660 meters).

The airplane had fixed wheeled landing gear which used rubber cords (bungie cords) for shock absorption. The wheel track was 4 feet, 10¾ inches (1.492 meters). A fixed skid was used at the tail.

The the S.XIII had an empty weight of 1,464 pounds (663 kilograms) and maximum takeoff weight of 1,863 pounds (845 kilograms).

The SPAD S.XIII C.1 was powered by a water-cooled, normally-aspirated 11.762 liter (717.769-cubic-inch-displacement) left-hand tractor ⁴ Hispano-Suiza 8B single-overhead-cam 90° V-8 engine, with a 5.3:1 compression ratio. The engine drove a fixed-pitch two-bladed laminated wood propeller through a 0.75:1 gear reduction. The Hispano-Suiza 8B was rated at 235 cheval vapeur (231.8 horsepower) at 2,300 r.p.m. It was 1.36 meters (4 feet, 5.5 inches) long, 0.86 meters (2 feet, 9.9 inches) wide, and 0.90 meters (2 feet, 11.4 inches) high. It weighed 236 kilograms (520.3 pounds).
The SPAD’s main fuel tank was behind the engine, with a gravity feed supply tank in the upper wing. The total fuel total capacity was about 30 gallons (114 liters). This was sufficient for two hours endurance at full throttle at 10,000 feet (3,048 meters), including climb.
The SPAD XIII had a maximum speed at Sea Level of 131.5 mph (211.6 kilometers per hour) at 2,300 rpm; and 105 mph (169 kilometers per hour) at its service ceiling of 18,400 feet (5,608 meters), at 2,060 r.p.m. The airplane’s absolute ceiling was 20,000 feet (6,096 meters).
The fighter was armed with two fixed, water-cooled, .303-caliber Vickers machine guns, or two air-cooled .30-caliber Marlin M1917 or M1918 aircraft machine guns, with 400 rounds of ammunition per gun, synchronized to fire forward through the propeller arc.
According to a report by the National Aeronautics and Space Administration,
. . .the SPAD XIII had the most favorable power loading of any of the aircraft considered and a high (for its day) wing loading. These characteristics coupled with a relatively low zero-lift drag coefficient and low drag area gave the SPAD the highest speed of any of the aircraft listed in the table. As shown by the data in figure 2.18, the climb characteristics of the SPAD were bettered only by three of the Fokker aircraft.

A total of 8,742 S.XIII C.1 fighters were built by nine different manufacturers. Only one, Société Kellner Frères Constructeurs serial number 4377, the oldest existing original airplane, is in flyable condition. It is in the collection of the Memorial-Flight Association at L’aérodrome de La Ferté-Alais (LFFQ)
