F8F Bearcat

The F8F Bearcat was a carrier-based fighter aircraft used by the US Navy until 1955. Designed and manufactured by Grumman, the F8F performed its first flight on August 21, 1944, entering service with the US Navy in 1945. Grumman built 1,266 units of this aircraft. The Bearcat was also used by the French Air Force during the First Indochina War to strike Viet Minh targets.

The Grumman F8F was a one-engined, one-seat aircraft with straight low wings. Powered by a Pratt & Whitney R-2800-34W piston engine, the first F8F-1 was marginally slower than the F4U Corsair, but it was more maneuverable and climbed faster. The Bearcat had a hydraulically operated landing gear. Armor protection had been provided for the pilot, engine and oil cooler. Structurally the fuselage of the F8F used flush riveting as well as spot welding, with a heavy gauge 302W aluminum alloy skin.

F7F Tigercat

The F7F Tigercat was a US Navy twin-engined fighter aircraft which saw action in the Korean War. The F7F was a piston-engined, straight-winged aircraft which could reach a top speed well in excess of the US Navy’s piston-engined aircraft; it was 71 mph faster than a Grumman F6F Hellcat at sea level. Since the Tigercat was too big and heavy to take off and land from carriers, the initial production series was only used from land bases by the USMC, as night fighters fitted out with APS-6 radar.

The F7F Tigercat was developed and built by Grumman, with the prototype first flying on November 2, 1943. Although it entered service with the USMC in 1944, this fighter did not see action in World War II, but five years later in Korea, flying night interdiction and fighter missions and shooting down several Polikarpov Po-2 biplanes. At first, they were single-seater F7F-1N aircraft, but Grumman engineers decided to add a second seat for a radar operator; these aircraft were designated F7F-2N.

F3D Skyknight

The F3D Skyknight was a carrier-based, straight-wing jet fighter aircraft used by the US Navy and Marine Corps during the Korean War. The F3D was designed by Edward Heinemman and manufactured by Douglas Aircraft Company. The Skyknight performed its first flight as a prototype on March 23, 1948, with the first batch being delivered by Douglas to the US Navy in June 1951. The F3D successfully replaced the Vought F4U Corsair and F7F Tigercat aircraft.

The Douglas F3D Skyknight was fitted with straight, mid wings which were folded when stored on board of the aircraft-carrier. It had two seats and was powered by two Westinghouse J34-WE-36 turbojet engines. The Skyknight avionics consisted of an improved Westinghouse AN/APQ-36 radar system. By March 1953, when the production ended, a total of 265 F3D aircraft had been manufactured. Although few F3D-1 aircraft were used primarily to train F3D crews and did not see combat, the F3D-2 saw extensive service during the Korean War, shooting down more enemy aircraft in Korea than any other Navy fighter aircraft.

F-94 Starfire

The F-94 Starfire was a jet, all-weather interceptor aircraft which was developed and manufactured by Lockheed for the US Air Force. The YF-94 prototype first flew on April 16, 1945, using seventy-five percent of the parts used in the earlier F-80 and T-33A aircraft. It was the first US production jet with an afterburner as it was equipped with an Allison J33-A-33 centrifugal-type turbojet on the F-94A, and a Pratt & Whitney J48-P-5 turbojet on the F-94C.

The Lockheed F-94 was a straight-wing design, similar to the Lockheed T-33 Shooting Star, with two seats. This aircraft entered service in May 1950 with the the 339th, 68th, 4th, and 319th squadrons deployed in Korea where it saw action. In this war, the F-94 Starfire was credited with several air to air victories, including the first jet vs. jet night victory.

U-2 Spy Plane

The U-2 Dragon Lady was a single-engine, spy plane used by the US Air Force and the Central Intelligence Agency during the Cold War. It was designed by American engineer Clarence Johnson and manufactured by Lockheed. The U-2 made its first flight on August 1, 1955, at the Groom Lake test site (Area 51), entering service in 1957. Lockheed built a total of 86 U-2 aircraft, of which only 25 are still active. Because of the high operating altitude, the pilot had to wear the equivalent of a space suit. The suit delivered the pilot’s oxygen supply and emergency protection in case cabin pressure was lost at high altitude.

The U-2 was a high-altitude, reconnaissance, sailplane-winged aircraft with a lift-to-drag ratio estimated in the high 20s and an operational ceiling of 70,000 feet (21,000 m). Early U-2 variants were powered by Pratt & Whitney J57 turbojet engines, but the U-2C, the U-2S, and TR-1A variants used the more powerful Pratt & Whitney J75 turbojet and the General Electric F118-101 turbofan. Optics for a large-format camera were developed to be used in the U-2. These new cameras had a resolution of 2.5 feet (76 cm) from an altitude of 60,000 feet (18,000 m). Balancing was so critical on the U-2 that the camera had to use a split film, with reels on one side feeding forward while those on the other side feed backward, thus maintaining a balanced weight distribution through the whole flight.

The U-2 Dragon Lady came to public attention when CIA pilot Francis Gary Powers was shot down over Soviet territory on May 1, 1960, causing the U-2 incident. On October 14, 1962, a U-2 from the 4080th Strategic Reconnaissance Wing, based at Laughlin Air Force Base near Del Rio, Texas, and piloted by Major Richard S. Heyser, photographed the Soviet military installing nuclear warhead missiles in Cuba, precipitating the Cuban Missile Crisis. Despite its high-altitude capability, the U-2 was vulnerable to the Soviet SAM earth-to-air missiles. That is the reason it was partially replaced by the supersonic SR-71 aircraft.

Specifications for the Lockheed U-2

Engine: one General Electric F118-101 turbofan.
Maximum speed: 500 mph (805 km/h).
Service ceiling: 70,000 ft (21,300 m).
Range: 6,405 mi (10,300 km).
Length: 63 ft (19.2 m).
Wingspan: 103 ft (31.4 m).

F7U Cutlass

The F7U Cutlass was a carrier-based fighter and ground-attack aircraft developed and produced by Chance Vought for the US Navy. The F7U performed its first flight on September 29, 1948; it was piloted by Vought’s Chief Test Pilot, J. Robert Baker. The aircraft entered service with the US Navy in July 1951. The F7U never saw action and was retired in March 1959, being replaced by the Douglas A-4 Skyhawk.

The Cutlass design featured swept wings with two wing-mounted tail fins and broad chord. The cockpit was located well forward to provide good visibility for the pilot during aircraft carrier approaches. The design was given the company type number of V-346 and then the designation F7U. The first production version was the F7U-1, which was powered by two J34-WE-32 engines. The F7U-3 was reequipped with two Westinghouse J46-WE-8B turbojets. However, the aircraft still lacked engine thrust and had many technical problems, causing accidents. As a result, its carrier landing and takeoff performance was poor. So, the pilots nicknamed it the "gutless cutlass." Vought built a total of 320 units.

Specifications for the F7U Cutlass

Engine: two Westinghouse J46-WE-8B turbojets.
Maximum speed: 680 mph (1,095 km/h).
Thrust/weight: 0.29

F4D Skyray

The F4D Skyray was a carrier-based, supersonic, fighter aircraft which was used by the US Navy during the Cold War. The F4D was designed by the American engineer Edward Heinemann in 1950, and manufactured by Douglas. The Skyray made its first flight on January 23, 1951, and was delivered to the United States Navy VC-3 Squadron in 1956. It was retired from service in 1964.

The F4D Skyray had sharply swept, rounded delta wings. Its design was named after the Manta ray fish which it resembled. The thick wing roots contained the air intakes which fed a single turbojet engine. Fuel was contained both in the wings and the deep fuselage. In September 1962, the Skyray was redesignated F-6. The F4D was designed for the high-altitude interception role with a spectacular rate and angle of climb, setting a new time to altitude record flying from a standing start to 49,221 ft (15,000 m) in 2 minutes and 36 seconds, all while flying at a 70° pitch angle.

AC-47 Spooky

The AC-47 Spooky was a twin-engine ground-attack aircraft used by the US Air Force during the Vietnam War. The AC-47 gunship development was based on the C-47 Skytrain transport plane airframe. The company that redesigned and manufactured it was the Douglas Aircraft Company. It entered service with the United States Air Force in Vietnam in 1965.

The C-47 was turned into the AC-47 gunship by mounting three 7.62mm General Electric miniguns to fire through two rear window openings and the side cargo door, all on the left (pilot’s) side of the aircraft. Douglas produced a total of 53 Spooky gunships. It was replaced by the AC-119 Shadow in 1968.

AC-119 Gunship

The AC-119 gunship was a heavily-armed, ground-attack, twin-engine aircraft which was used by the US Air Force during the Vietnam War. The AC-119 was produced in two variants by Fairchild Aircraft Company: the AC-119G Shadow and the AC-119K Stinger. In Vietnam they flew alongside the AC-130 Spectre gunship, replacing the outdated AC-47 Spooky. The Shadow entered service in 1968 and was retired in 1971, but it continued in service with the South Vietnamese Air Force until 1975.

The AC-119 gunship was developed from the C-119 Flying Boxcar, which was a transport aircraft, for interdiction of the Ho Chi Minh Trail. The AC-119Gs were placed in the 71st Special Operations Squadron, while the AC-119Ks were deployed with the 18th Special Operations Squadron. During the Vietnam War, only five AC-119 Gunship IIIs were lost to different causes.

AC-130 Gunship

The AC-130 gunship is a four-engine ground-attack aircraft used by the US Air Force for supporting ground troops, escorting convoys, and flying urban operations. The AC-130 gunship was developed from the C-130 Hercules transport plane. The aircraft airframe is built by Lockheed, while Boeing is responsible for the conversion into a gunship and for aircraft support. The AC-130 first flew in 1966 and entered active service with the United States Air Force in 1968. Variants in active service: AC-130E Pave Aegis, AC-130H Spectre, and AC-130U Spooky II.

The AC-130H Spectre is fitted with side-firing weapons which are integrated with sophisticated sensors, navigation and fire control systems to provide precision firepower. The Spectre can spend long periods flying over their target area at night and in adverse weather. The sensor suite is composed of a television sensor, infrared sensor, and radar. These sensors allow the gunship to visually or electronically identify friendly ground forces and targets in most weather conditions. The AC-130U Spooky II is equipped with the AN/APQ-180, a synthetic aperture radar for long-range target detection and identification. The gunship’s navigational devices include inertial navigation systems and a Global Positioning System. Using the technologies developed in the 1990s, the AC-130U can strike two targets simultaneously. It also has twice the munitions capacity of the AC-130H.

The AC-130 was effectively used by the US Air Force in the Vietnam War, in the 1989 invasion of Panama, in the Gulf War, in Operation Enduring Freedom, and in Operation Iraqi Freedom.
