A Hawker Hunter prototype was exhibited to the public for the first time at the 1951 Farnborough Air Show.
In April of 1952 a Hawker Hunter officially surpassed Mach 1. It was piloted by Nevil Duke, a test pilot.
The first production Hawker Hunter took to the sky on May 16, 1953. However, it together with an additional 22 aircraft of the first production lot were used solely for testing.
On Sept. 7, 1953 a Hawker Hunter set a 727.6 mph level flight official speed record.
The first Hawker Hunter aircraft were deployed in mid 1954. They provided the RAF with their first fighter aircraft capable of transonic speeds.
Initially Hawker Hunter aircraft had problems when their guns firing caused the engine to flame out at altitudes above 30,000 feet. However this was quickly remedied. Another issue was that the cartridges remaining after the bullets were fired tended to strike the lower fuselage causing damage and the possibility of being ingested into the engine. Cartridge collectors were fitted to new models and retrofitted to older ones.
Other changes to the aircraft as it developed increased engine reliability, fuel and ordnance.
While Hawker Hunter aircraft were originally powered by Avon engines, other production models were produced simultaneously which were powered by the Armstrong Siddeley Sapphire engine. However, few aircraft were eventually equipped by the Armstrong engines.
In an effort to improve the range and payload of the Hawker Hunter, the model F.4 was developed. It was equipped with the Avon 115 turbojet producing more thrust. The aircraft's wings were made stronger to enabled it to carry fuel tanks, bombs, and rockets.
Hawker Hunters of the 263 Squadron, equipped with Armstrong engines, were the first to see action. They flew sorties against Egyptian ground targets during the Suez Campaign.
The 10,000 lb. thrust Avon 203 engine was fitted to the Hawker Hunter F. Mk 6. It increased both aircraft speed and climb rate. This was the version of the aircraft built in the greatest numbers. However, early production aircraft versions had a tendency to pitch up at high speeds. This was remedied by extended the leading edges of the outer portion of the wing, resulting in a saw-tooth look. An improved starting system allowed the Mk 6 to scramble more quickly than previous models.
Some 19 countries around the world used the Hawker Hunter. They saw action with the Indian Air Force in their fights with Pakistan. Eight Pakistani jets were claimed as downed by Indian Hawker Hunter aircraft.
Jordanian Hawker Hunter aircraft were deployed against Israel during the Six Day War.
Belgium, Denmark, Holland, Singapore, Sweden, and Switzerland all produce Hawker Hunter aircraft under license.
Today many of the aircraft can be found in museum displays, and performing at air shows throughout the world.
A total of over 1,970 Hawker Hunter aircraft were manufactured in five versions.
That's Keith Mitchell with his 33 percent scale scratch built Hawker Hunter. It took seven years to build. Power comes from a pair of 38 lbf. thrust turbines going into a single exhaust. Estimated top speed is between 120 and 140 mph. Weight is around 160 lbs.
The Hawker Hunter from a kit by Mick Reeves Models has a wingspan of 63 in. and a length of 93 in. It has an epoxy fuse and balsa built up wings. You will need a turbine engine producing a minimum of 15 lbs. of thrust for power. All up weight is about 22 1/2 lbs.
The Hawker Hunter kit by Green Air Designs features Depron construction. It has a wingspan of 24 in. and a length of 32 in. Green Air recommends powering it with their Viper-Tec 48 or 50 mm motor and EDF unit.
West Wings has a Hawker Hunter kit. Wingspan is 28 in. and the fuselage is 38 in. long. Materials used to build the model are balsa and plywood. You can use a Speed 480 size motor driving a WeMoTec Mini Fan.
Airworld Modellbau has a Hawker Hunter. Its wingspan is 81 in. and length is 110 in. You will need turbine engines with from 34 to 38 lbs. of thrust for power.
HT Modellbau has a Hawker Hunter with a 59 in. wingspan and length of 82 in. For power it needs from a 18 to 26 lb. thrust turbine engine.
