Focke-Wulf Fw 200 S-1 D-ACON

28–30 November 1938: The first prototype Focke-Wulf Fw 200 Condor, D-ACON, flew from Berlin, Germany, to Tokyo, Japan, to demonstrate the long-distance capabilities of the new civil airliner.

The Condor’s flight crew was the same as that which had made a previous Berlin–New York transatlantic flight, 10–11 August 1938. Deutsche Luft Hansa Kapitän Alfred Henke, Hauptmann Rudolf Freiherr von Moreau, of the Luftwaffe, co-pilot; Paul Dierberg, flight engineer; Walter Kober, radio operator. Senior radio operator Georg Khone was an additional crew member. (He had originally been scheduled to make the transatlantic flight.) For this flight there  was a single passenger, verkaufsdirecktor (sales director) Heinz Junge.¹

The Condor took off from Flugplatz Berlin-Staaken at 3:53 p.m., on 28 November, and flew to Basra, Kingdom of  Iraq. The Great Circle distance between the two cities is 2,305 miles (3,710 kilometers)

After refueling, the Fw 200 took off for its next destination, Karachi Air Port in the Sindh province of the British India (now, Pakistan). The distance for the second leg of the journey was 1,238 miles (1,993 kilometers).

From Karachi, Captain Henke and his crew flew on to the city of Hà Nội, in the Protectorate of Tonkin, Indochine française. The Great Circle distance for the third leg is 2,480 miles (3,991 kilometers).

The final segment was from Hanoi to Tokyo, Japan, a distance of 2,281 miles (3,671 kilometers). The Condor arrived at Tachikawa Airfield in the western part of Tokyo at 10:40 p.m., 30 November.

The total elapsed time for the journey was 46 hours, 18 minutes, 19 seconds. The actual flight time was 42 hours, 00 minutes. The Condor’s average speed from Berlin to Tokyo was 198.308 kilometers per hour (123.223 miles per hour).

Captain Henke and his crew established a Fédération Aéronautique Internationale (FAI) World Record for Speed Over Courses for the journey from Berlin to Hanoi, with an average speed of 243.01 kilometers per hour (150.999 miles per hour).² The total elapsed time, Berlin–Hanoi, was 34 hours, 17 minutes, 27 seconds.

The Condor’s crew was received by Emperor Hirohito.

The Japanese airline Nihon Koku Yuso Kabushiki Kaisha (NYKK) agreed to buy five Focke-Wulf Fw 200 airliners. The Imperial Japanese navy expressed interest in a maritime patrol version.

The Associated Press news agency reported:

Nazi Airmen Start Berlin to Tokyo Hop

     Berlin, Nov. 28—(AP)—A fast four-motored Focke-Wulf Condor plane took off today for Tokyo with a crew of five and one passenger, to show the orient, especially Japan, Germany’s latest achievements in airplane building.

     With only three stops scheduled en route—at Basra, Iraq; Karachi, India, and Hanoi, French Indo-China—it was expected that the entire distance of 9,300 miles would be covered in from 50 to 55 hours.

     Lufthansa officials, however, declared no record would be sought. They said the flight was intended to return the visit of Japan’s “Divine Wind,” which flew here in April, 1937.

     But no secret was made of the fact that Japan has been negotiating for purchase of German commercial planes, for which reason the big Condor was chosen to show its paces.

     Officials said it would return by way of Batavia, capital of the Netherlands East Indies, and Amsterdam in order to show the Royal Dutch air line that its time of six days between those points can be lowered to four.

     The Germans may make a side -trip to Manchoukuo, where purchase of German planes is also being negotiated.

     It was expected they would be back in Berlin by December 17.

(Chicago Tribune Press Service.)

     TOKIO, Nov. 30.—Completing an 8,375 mile flight from Berlin to Tokio in 46 hours and 41 minutes, five German airmen and one passenger landed their plane at 10:35 o’clock tonight on Tachikawa army airfield on the outskirts of Tokio. The plane, a four-motor Focke-Wulf Condor capable of carrying twenty-six passengers, left Berlin on Monday.

     The silver colored monoplane made only three stops en route, at Basra, Iraq; Karachi, India, and Hanoi, French Indo-China. It averaged 180 miles and hour, including stopovers. Capt. Alfred Henke said the crew encountered little difficulty. They were in constant radio contact with Japanese stations.

Fw 200 S-1 D-ACON (Bernhard D.F. Klein Collection/1000 Aircraft Photos)

D-ACON was the prototype Condor, designated Fw 200 V1, Werk-Nr. 2000. It had first flown at Neulander Feld, site of the Focke-Wulf plant in Bremen, Germany, 27 July 1937. The test pilot was Kurt Waldemar Tank, an aeronautical engineer and the airplane’s designer.

Tank had proposed the airplane to Deutsche Luft Hansa as a long-range commercial transport for routes from Europe to South America. While British and American airlines were using large four-engine flying boats for transoceanic flight, their heavy weight and aerodynamic drag reduced the practical passenger and cargo loadings. A lighter-weight, streamlined land plane would be faster and could carry more passengers, increasing its desirability and practicality. Also, while the flying boats had to make an emergency water landing if one engine failed during the flight, the Focke-Wulf Condor was designed to be able to remain airborne with just two engines.

D-ACON (Klassiker fer Luftfahrt)

The Fw 200 V1 was an all-metal low-wing monoplane powered by four engines, with retractable landing gear. It had a flight crew of four, and was designed to carry a maximum of 26 passengers. It was 78 feet, 0 inches (27.774 meters) long with a wingspan of 108 feet, 0 inches (32.918 meters) and overall height of 20 feet, 0 inches (6.096 meters). The airliner had an empty weight of 24,030 pounds (10,900 kilograms) and gross weight of 37,479 pounds (17,000 kilograms). This increased to 39,683 pounds (18,000 kilograms) after modification to the Fw 200 S-1 configuration.

As originally built, the prototype Condor was powered by four air-cooled, supercharged 1,690.537-cubic-inch-displacement (27.703 liters) Pratt & Whitney Hornet S1E-G single-row 9-cylinder radial engines with a compression ratio of 6.5:1 and gear reduction ratio of 3:2. The S1E-G was rated at 750 horsepower at 2,250 r.p.m. to 7,000 feet (2,134 meters), and 875 horsepower at 2,300 r.p.m. for takeoff. It was 4 feet, 1.38 inches (1.254 meters) in diameter, 4 feet, 6.44 inches (1.383 meters) long, and weighed 1,064 pounds (483 kilograms).

Brandenburg‘s Pratt & Whitney engines were later replaced by Bayerische Motorenwerke AG BMW 132 L engines. BMW had been producing licensed variants of the Pratt & Whitney Hornet since 1933, and had incorporated their own developments during that time. The BMW 132 had a displacement of 27,72 liters and a gear reduction ratio of 0,62:1, and turned a two-bladed Zweiblatt-Versstellpropeller constant-speed propeller, based on Hamilton-Standard design,  with a diameter of 3,35 m

The Fw 200 V1 had a maximum speed of 233 miles per hour (375 kilometers per hour) at Sea Level. Its cruising speed was 205 miles per hour (330 kilometers per hour) at 10,000 feet (3,048 meters). The airliner’s service ceiling was 20,000 feet (6,096 meters). It could maintain level flight at 13,000 feet (3,962 meters) with 3 engines, and 10,000 feet (3,048 meters) with just two engines running. Its range at cruise speed with a 7,000 pound (3,175 kilogram) payload was 775 miles (1,247 kilometers).

For the Berlin-to-New York flight, the Fw 200’s fuel capacity was increased to 2,400 gallons (9,084 liters).

Fw 200 S-1 D-ACON

On 6 December 1938, while on approach to Manila, capital city of the Commonwealth of the Philippines, all four of D-ACON’s engines stopped. Unable to reach the airfield, the Condor was ditched in Manila Bay. All aboard were quickly rescued. The cause of the engines failing was fuel starvation. One source states that the crew had selected the wrong tanks. Another source says that a fuel line had broken. A third cites a fuel pump failure.

The wreck of the first Condor was recovered, however, the airplane was damaged beyond repair.

22 November 1961: In recognition of the 50th Anniversary of Naval Aviation, a number of speed and altitude record attempts were planned, using the U.S. Navy’s new McDonnell YF4H-1 Phantom II fighter. On the morning of 22 November, Lieutenant Colonel Robert Bradford Robinson, Jr., United States Marine Corps, took off from Edwards Air Force Base on Operation Skyburner, an attempt to set a new World Absolute Speed Record. He was flying the second Phantom II built, Bu. No. 142260.

The Phantom carried three external fuel tanks for this flight. It had a 600-gallon (2,271.25 liter) centerline tank and two 370-gallon (1,400.6 liter) wing tanks. Robinson flew southeast toward NAS El Centro, then turned back to the northwest. Over the Salton Sea, he began to accelerate the YF4H-1 to build up speed for the record run over a measured twenty-mile course back at Edwards AFB. The Phantom’s two General Electric J79-GE-3A afterburning turbojets used a tremendous amount of fuel at full throttle and the centerline fuel tank was quickly emptied. Robinson jettisoned the empty tank over the Chocolate Mountain gunnery range. Continuing to accelerate, the two wing tanks were next jettisoned as they ran dry, this time at Bristol Dry Lake.

The Phantom entered the east end of the speed course in full afterburner. Having burned off more than 1,300 gallons of fuel, 142260 was much lighter now, and aerodynamically cleaner after dropping the external tanks. Robinson exited the west end of the 20-mile (32.2 kilometer) course in less than one minute.

Fédération Aéronautique Internationale rules require that a speed record must be made with two passes in opposite directions. The average speed of the two runs is the record speed. The Phantom was flying so fast that it covered another 105 miles (169 kilometers) before it could turn around. During the turn, it was still traveling at 0.9 Mach.

Robinson again put the engines in afterburner as he approached the course from the west. On the second run, the fighter was even lighter and its recorded speed was more than 1,700 miles per hour (2,736 kilometers per hour). The average of the two runs was calculated at 2,585.425 kilometers per hour (1,606.509 miles per hour.) This was the new FAI Absolute World Speed Record.¹

For his accomplishment, Lieutenant Colonel Robinson was awarded the Distinguished Flying Cross by Secretary of the Navy John B. Connally. The presentation took place on 25 November 1961 at Newport News, Virginia, during the commissioning of USS Enterprise CVA(N)-65.

In the next few weeks, the same YF4H-1 would establish a world record for sustained altitude—20,252 meters (66,444 feet).² Two years earlier, 6 December 1959, in Operation Top Flight, 142260 had established a world record for absolute altitude when it zoom-climbed to 98,557 feet (30,040 meters).³

Bob Robinson attended Orange Union High School, graduating in 1941. He participated in all varsity sports, and was selected to attend the Boys’ State leadership program. He earned a bachelor of science degree at Washington University, St. Louis, Missouri.

Robinson entered the United States Marine Corps on 26 August 1942. He received the wings of a Naval Aviator and was commissioned as a second lieutenant on 1 December 1943.

2nd Lieutenant Robinson married Miss Lavonne Jean David at Nueces, Texas, 23 December 1943. They would later have a son, Robert Bradford Robinson III (and a grandson, Robert Bradford Robinson IV)

During the Battle of Okinawa, Lieutenant Robinson flew the radar-equipped Grumman F6F-3N Hellcat night fighter with VMF(N)-543.

Lieutenant Robinson was promoted to the rank of first lieutenant, 31 March 1945. Following World War II, Lieutenant Robinson was assigned to VMF-311, and became one of the first Naval Aviators to qualify in turbojet-powered aircraft. The squadron initially flew the Lockheed TO-1 Shooting Star (P-80), and later transitioned to the Grumman F9F Panther.

Lieutenant Robinson was promoted to the rank of captain 1 April 1950. VMF-311 was sent to the Korean war zone in November 1950, initially operating from Yokosuka Air Base in Japan. The squadron flew close air support missions in support of the amphibious assault of Inchon, and at the Battle of the Chosin Reservoir. Captain Robinson returned to night fighter operations when he joined Marine All-Weather Squadron 513 (VMF(N)-513) on 13 January 1951.

Captain Robinson was promoted to the rank of major, 31 December 1954. He completed the six-month course at the Naval Test Pilot School, NAS Patuxent River, Maryland, graduating in March 1959 (Class 21).

In 1963, Lieutenant Colonel Robinson retired from the Marine Corps after 20 years’ service. He was then employed as a test pilot for the McDonnell Aircraft Corporation at St. Louis, Missouri. He remained with the company for 30 years.

Mrs. Robinson died 7 February 1997, after 53 years of marriage. Bob Robinson later married Mrs. Julian Brady (née Elizabeth Catchings), the widow of a long-time friend.

Robert Bradford Robinson, Jr., died 28 September 2005 at McComb, Mississippi. He was buried at the Hollywood Cemetery in McComb.

19–20 November 1945: A Bell-Atlanta B-29B-60-BA Superfortress, 44-84061, named Pacusan Dreamboat, piloted by Colonel Clarence Shortridge Irvine and Lieutenant Colonel G.R. Stanley, flew non-stop and unrefueled from Guam, the largest and southernmost island in the Mariana Islands of the Western Pacific, to Washington, D.C. The four-engine heavy bomber covered the 8,198 miles (13,193 kilometers) in 35 hours, 5 minutes. It set a Fédération Aéronautique Internationale (FAI) record for Distance in a Straight Line:  12,739.59 kilometers (7,916.01 miles).¹

Pacusan Dreamboat was modified specifically for a series of long-distance flights. A standard production B-29B, a light-weight variant of the Boeing B-29 Superfortress, it did not have the four power gun turrets with their .50-caliber machine guns. A radar-directed 20 mm cannon and two .50-caliber machine guns in the tail were the only defensive weapons. Much of the standard armor plate was also deleted. It weighed 69,000 pounds (31,298 kilograms) empty and 137,000 pounds (62,142 kilograms) fully loaded. Pacusan Dreamboat was further lightened. The tail guns were removed and the tail reshaped. It had an empty weight of 66,000 pounds (29,937 kilograms). Its takeoff weight on this flight was 151,000 pounds (68,492 kilograms).

Pacusan Dreamboat carried a 12-man crew and 10,000 gallons (37,854 liters) of gasoline.

19 November 1952: Captain James Slade Nash, U.S. Air Force, a test pilot at the Air Force Flight Test Center, Edwards Air Force Base, California, flew a North American Aviation F-86D-20-NA Sabre, 51-2945, to a Fédération Aéronautique Internationale (FAI) World Absolute Speed Record at the Salton Sea, in the Colorado Desert of southeastern California.

Operating out of NAS El Centro, Captain Nash flew four passes over a 3-kilometer course at an altitude of 125 feet (38 meters). The official average speed was 1,124.14 kilometers per hour (698.508 miles per hour).¹ He was awarded the FAI’s Henry de la Vaulx Medal for achieving the World Absolute Speed Record.

The Desert Sun reported:

Sabre-Jet Sets new World Speed Mark at Salton Sea

Record of 699.9 Mile Per Hour Established in Four Flights over Below Sea Level Course

     The desert area,  few miles east of Palm Springs, was the setting for a new international airplane speed record last week when an F-86D Sabre jet roared over Salton Sea at 699.9 miles an hour. It was reported that in test runs previously the plane had exceeded 700 miles an hour.

     Risking his life to set the new record was Capt. Slade Nash, a 31-year-old Sioux City, Iowa man with three children. His wife, but not his three daughters, watched as Captain Nash barreled the swept-wing North American interceptor jet four times over the course, as close as 100 feet to the ground although he could have flown it at 328 feet.

      Nash had only to hit 676 miles an hour to shatter the previous world speed record set September 15, 1948, by Maj. Richard L. Johnson, air material command test pilot, at Edwards Air Force Base in an earlier Sabrejet—the F-86A. Johnson’s Mark was 670.981 m.p.h. and Nash was required to fly 5 m.p.h. faster to set a new record.

     NASH’S SABRE jet carried a full rocket load. Adding hazard to the inherent danger of gunning a plane to near 700 m.p.h. was the low altitude below sea level—at when the run for record was made.

     Fuel requirements are much higher at sea level than at high levels and air pressure on the plane is about four times greater. In addition, aerodynamic problems of drag, buffet, stability and structural strength are greatly increased at sea level. However, low altitude and higher temperatures make higher speeds possible.

     CONDITIONS WERE NOT ideal for the test. Officials had hopes for 85-degree temperatures, but, at approximately 1:45 p.m., when the speed runs were made, the reading was only 75.5 degrees.

     Nash came within shouting distance of the speed of sound—about 760 m.p.h. at sea level. The speed of sound—called MACH 1—has many times been surpassed by jet planes in dives at high altitudes—in fact, most jet pilots pass this barrier at some time or another—but never under the considerably more difficult conditions of an official attempt to break the world speed record.

     NASH ALSO SET another record—being the first pilot to break a world speed record at below-sea-level altitudes. The Salton Sea is 235 feet below sea level and Nash’s Sabre jet was not believed to have gone above the sea level mark during his speed runs.

     Scene of the run was a desolate, gully-slashed barren shore land about a mile and a half below Durmid, a railroad crossing, and just south of the Riverside-Imperial county lines.

     About 100 newsmen, cameramen, manufacturers’ representatives and Air Force members were present. Head timer was C.S. Logsdon of Washington, D.C., director of the NAA Contest Division. Rules of the Federation Aeronautique Internationale and the Nationals Aeronautics [sic] Association (NAA) were followed.

     Official timing was made with high speed movie cameras. Processing of those films was necessary before the exact official speed of the run could be determined.

The The North American Aviation, Inc. F-86D Sabre was an all-weather interceptor developed from North American Aviation F-86 fighter. It was the first single-seat interceptor, and it used a very sophisticated—for its time—electronic fire control system. It was equipped with search radar and armed with twenty-four unguided 2.75-inch (69.85 millimeter) Mk 4 Folding-Fin Aerial Rockets (FFAR) rockets carried in a retractable tray in its belly.

The aircraft was so complex that the pilot training course was the longest of any aircraft in the U.S. Air Force inventory, including the Boeing B-47 Stratojet.

The F-86D was larger than the F-86A, E and F fighters, with a longer and wider fuselage. It was also considerably heavier. The day fighter’s sliding canopy was replaced with a hinged “clamshell” canopy. A large, streamlined radome was above the reshaped engine intake.

The F-86D Sabre was 40 feet, 3¼ inches (12.275 meters) long with a wingspan of 37 feet, 1½ inches (11.316 meters), and overal height of 15 feet, 0 inches (4.572 meters). The interceptor had an empty weight of 13,518 pounds (6,131.7 kilograms), and maximum takeoff weight of 19,975 pounds (9,060.5 kilograms). It retained the leading edge slats of the F-86A, F-86E and early F-86F fighters. The horizontal stabilizer and elevators were replaced by a single, all-moving stabilator. All flight controls were hydraulically boosted. A “clamshell” canopy replaced the sliding unit of earlier models.

The F-86D was powered by a General Electric J47-GE-17 engine. This was a single-shaft, axial-flow turbojet with afterburner. The engine had a 12-stage compressor, 8 combustion chambers, and single-stage turbine. The J47-GE-17 was equipped with an electronic fuel control system which substantially reduced the pilot’s workload. It had a normal (continuous) power rating of 4,990 pounds of thrust (22.20 kilonewtons); military power, 5,425 pounds (24.13 kilonewtons) (30 minute limit), and maximum 7,500 pounds of thrust (33.36 kilonewtons) with afterburner (15 minute limit). (All power ratings at 7,950 r.p.m.) It was 18 feet, 10.0 inches (5.740 meters) long, 3 feet, 3.75 inches (1.010 meters) in diameter, and weighed 3,000 pounds (1,361 kilograms).

The maximum speed of the F-86D was 601 knots (692 miles per hour/1,113 kilometers per hour) at Sea Level, 532 knots (612 miles per hour/985 kilometers per hour) at 40,000 feet (12,192 meters), and 504 knots (580 miles per hour/933 kilometers per hour)at 47,800 feet (14,569 meters).

The F-86D had an area intercept range of 241 nautical miles (277 statute miles/446 kilometers) and a service ceiling of 49,750 feet (15,164 meters). The maximum ferry range with external tanks was 668 nautical miles (769 statute miles/1,237 kilometers). Its initial rate of climb was 12,150 feet per minute (61.7 meters per second) from Sea Level at 16,068 pounds (7,288 kilograms). From a standing start, the F-86D could reach its service ceiling in 22.2 minutes.

The F-86D was armed with twenty-four 2.75-inch (69.85 millimeter) unguided Folding-Fin Aerial Rockets (FFAR) with explosive warheads. They were carried in a retractable tray, and could be fired in salvos of 6, 12, or 24 rockets. The FFAR was a solid-fuel rocket. The 7.55 pound (3.43 kilogram) warhead was proximity-fused, or could be set for contact detonation, or to explode when the rocket engine burned out.

The F-86D’s radar could detect a target at 30 miles (48 kilometers). The fire control system calculated a lead-collision-curve and provided guidance to the pilot through his radar scope. Once the interceptor was within 20 seconds of its target, the pilot selected the number of rockets to fire and pulled the trigger, which armed the system. At a range of 500 yards (457 meters), the fire control system launched the rockets.

Between December 1949 and September 1954, 2,505 F-86D Sabres (sometimes called the “Sabre Dog”) were built by North American Aviation. There were many variants (“block numbers”) and by 1955, almost all the D-models had been returned to maintenance depots or the manufacturer for standardization. 981 of these aircraft were modified to a new F-86L standard. The last F-86D was removed from U.S. Air Force service in 1961.

17 November 1954: Lionel Peter Twiss, Chief Test Pilot for Fairey Aviation Company Ltd., was flying the company’s experimental supersonic airplane, the Fairey Delta 2, WG774, from the aircraft test center at RAF Boscombe Down, Salisbury, Wiltshire, England. This was the FD.2’s fourteenth flight.

When about 30 miles (48 kilometers) from the airfield and climbing through 30,000 feet (9,144 meters), the airplane’s fuel supply was interrupted and the engine flamed out.

Unwilling to lose a valuable research aircraft, Twiss decided to stay with the Delta 2 rather than ejecting, and he glided back to Boscombe Down, descending through a layer of cloud at 2,500 feet (762 meters). Without the engine running, the aircraft had insufficient hydraulic pressure to completely lower the landing gear and only the nosewheel strut locked in place. The FD.2 touched down at 170 miles per hour (274 kilometers per hour) and was seriously damaged.

WG774 was out of service for nearly a year. The wings had to be replaced and those which had originally been built for structural tests were used.

For his effort to save a valuable research aircraft, Peter Twiss was awarded the Queen’s Commendation for Valuable Service in the Air. Notice of the award was published in The London Gazette, 22 February 1955, at Page 1094:

On 10 March 1956, Peter Twiss flew WG774 to set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15km/25km Straight Course at an average speed over a 9-mile course, flown between Chichester and Portsmouth at and altitude of 38,000 feet (11,582 meters). Two runs over the course were made, with first averaging 1,117 miles per hour (1,798 kilometers per hour) and the second, in the opposite direction, was 1,147 miles per hour. (1,846 kilometers per hour). The FD.2 had averaged 1,822 Kilometers per hour (1,132 miles per hour)—Mach 1.731. ¹

Twiss had broken the previous record of 1,323.312 kilometers per hour (822.268 miles per hour) which had been set by Colonel Horace A. Hanes, U.S.Air Force, flying a North American Aviation F-100C Super Sabre over Edwards Air Force Base, California. ²

Peter Twiss was the first British pilot, and the FD.2 the first British airplane, to exceed 1,000 miles per hour (1,609 kilometers per hour) in level flight. Twiss is also the last British pilot to have held a World Absolute Speed Record.

For his services as a test pilot, Lieutenant-Commander Lionel Peter Twiss, D.F.C. and Bar, was appointed Officer of the Most Excellent Order of the British Empire, 13 June 1957.

The Fairey Aviation Company, Ltd., Delta 2 WG774 (c/n F9421) is the first of two single-place, single-engine delta-wing research aircraft which had been designed and built to investigate transonic and supersonic speeds. It first flew 6 October 1953 with Chief Test Pilot Peter Twiss in the cockpit.

In its original configuration, the FD.2 is 51 feet, 7½ inches (15.735 meters) long with a wingspan of 26 feet, 10 inches (8.179 meters) and overall height of 11 feet (3.353 meters). The wings’ leading edge were swept to 59.9° with an angle of incidence of +1.5°. Ailerons and flaps were at the trailing edge and acted in place of elevators. In its original configuration it had an empty weight of approximately 11,000 pounds (4,990 kilograms) and the all-up weight at takeoff was 14,109 pounds (6,400 kilograms).

The FD.2 was powered by a Rolls-Royce Avon RA.28R afterburning turbojet engine which produced 9,530 pounds of thrust (42.392 kilonewtons), or 11,820 pounds (52.578 kilonewtons) with afterburner (“reheat”). This was a single-shaft axial-flow turbojet with a 15-stage compressor and 2-stage turbine. The RA.28 was 10 feet, 3.0 inches (3.124 meters) long, 3 feet, 5.5 inches (1.054 meters) in diameter, and weighed 2,869 pounds (1,301 kilograms).

WG774 and its sistership, WG777, were used for flight testing throughout the 1960s. WG774 was modified as a test aircraft to study various features of the planned British Aerospace Concorde. The landing gear struts were lengthened and the fuselage extended by six feet. It received a “drooped” nose section for improved pilot visibility during takeoff and landings. New wings were installed which had an ogee-curved leading edge. With these modifications WG774 was redesignated BAC 221. In this configuration, WG774 was tested to Mach 1.65 at 40,000 feet (12,192 meters).

WG774 was retired in the early 1970s. It is on display at the Fleet Air Arm Museum, Yeovilton, Somerset, England.
