Testing of a " Nihon Hitori " (Japan Alone in Japanese) 2020 campaign where the 201 & 203 JASDF Squadrons of F-15Js hold the line against a red tide of Flankers until reinforcements arrive to start shoving the Russians off of the Kurils... and then F-35As & F-2As kick a** ending with an explosive air-sea battle.

While testing of the Tempest prototypes was still underway in 1942, the Hawker design team began to study ways to improve and lighten the fighter aircraft. Some of their ideas were influenced by the study of a German Focke-Wulf Fw 190 A-3 that had inadvertently landed in Britain in June 1942. The Fw 190 proved smaller and lighter that its Hawker-built contemporaries. In September 1942, the British Air Ministry issued Specification F.6/42 calling for a new fighter aircraft. Hawker proposed three versions of its improved Tempest, each to be powered by a different engine: the V-12 Rolls-Royce Griffon, the 18-cylinder Bristol Centaurus radial, and the H-24 Napier Sabre.
The Air Ministry supported Hawker’s designs under Specification F.2/43 issued in February 1943. In April 1943, Specification N.7/43 was issued for a new Navy fighter. Sydney Camm, Hawker’s chief designer, felt that arresting gear and folding wings could be added to the “improved Tempest” design to make it meet the requirements laid out in N.7/43. This plan was approved, and Specification N.22/43 was issued to Hawker for the new Navy fighter. Around this time, the two new Hawker aircraft received their official names: Fury (for the Royal Air Force’s land-based version) and Sea Fury (for the Fleet Air Arm’s naval version).
From the beginning, the preferred power plants were the Napier Sabre for the Fury and the Bristol Centaurs for the Sea Fury. Although the detailed design drawings for the Sabre-powered Fury were finished first, developmental delays of the new Sabre VII (NS.93/SM) engine resulted in the Centaurus- and Griffon-powered Furys being completed first. The Centaurus-powered Fury (NX798) first flew on 1 September 1944 followed by the Griffon-powered Fury (LA610) on 27 November 1944. Although the Air Ministry ordered 200 Sabre-powered Fury I aircraft in August 1944, there were rumors that Sabre production would be shut down following the war’s end. In October 1944, the Ministry of Aircraft Production (MAP) assured Hawker that Sabre production would continue. In November 1944, the MAP requested a Sabre-powered Fury prototype be built utilizing the Griffon-powered LA610 airframe. However, in February 1945 the Fury I order was reduced by 50 aircraft to 150. But in March 1945, two additional Sabre-powered prototypes (VP207 and VP213) were requested. Work to install a Sabre engine in LA610 began in July 1945. With the war over and the future of fighting aircraft pointing toward jet power, orders for the Fury I were reduced again in September 1945 to 120 units.
In December 1945, the Air Ministry had informed Hawker that ground attack would be the Fury I’s primary role. Hawker felt the aircraft was not suited for this because of its liquid-cooled engine, and it did not have the armour needed for a ground attacker. As a result, in February 1946, the number of Furys on order was further reduced to 60—and even those were in jeopardy. During this time, modifications of the LA610 airframe had been completed, but the Sabre VII engine was not ready.
Rather than wait for the engine, a Sabre VA (2,600 hp / 1,939 kW) was substituted. Soon, a Sabre VII was installed, and Fury LA610 was flown for the first time with its intended power plant on 3 April 1946. While the rest of the aircraft remained the same as the other prototypes, the power section of LA610 was completely different. A streamlined cowling was installed to cover the liquid-cooled Sabre engine. Coolant radiators were installed in the inboard wing sections, replacing additional fuel tanks. Cooling air would enter the wing’s leading edge, pass through the radiators, and exit via shutters under the wing. This configuration was similar to that used on the sole Tempest I prototype (HM599)—production did not occur because the Air Ministry perceived the wing radiators as too vulnerable to combat damage. The radiator shutters of the Fury I were automatically controlled based on engine temperature. A split duct under the spinner supplied intake air to the engine via the duct’s upper section. Air from the lower duct was directed through engine oil coolers and then out the bottom of the cowling. Not only was it one of the most beautiful aircraft ever built, the Sabre-powered Fury proved to be the highest performance piston-engine aircraft built by Hawker. The 24-cylinder Napier Sabre engine was a horizontal H layout with two crankshafts. The engine had a 5.0 in (127 mm) bore, 4.75 in (121 mm) stroke, and displaced 2,238 cu in (36.7 L). The Sabre VII utilized water/methanol injection to boost power and was capable of 3,055 hp (2,278 kW). To transfer this power to thrust, the Fury I used a 13 ft 3 in (4.0 m) four-blade Rotol propeller. A five-blade propeller like the Sea Fury’s 12 ft 9 in (3.9 m) Rotol unit was considered, but the decreased weight of the four-blade unit proved decisive in its adoption.
The Sabre-powered Fury had a top speed of 483 mph (777 km/h) at 18,500 ft (5,639 m) and 422 mph (679 km/h) at sea level. In contrast, the 2,560 hp (1,909 kw) Centaurus-powered Sea Fury had a top speed 460 mph (740 km/h) at 18,000 ft (5,487 m) and 380 mph (612 km/h) at sea level. The Sabre Fury’s initial rate of climb was 5,480 ft/min (27.8 m/s), and it could reach 20,000 ft (6,096 m) in 4.1 minutes. By comparison, The Sea Fury’s initial rate of climb was 4,320 ft/min (21.9 m/s), and it took 5.7 minutes to reach 20,000 ft (6,096 m). The Fury I’s service ceiling was 41,500 ft (12,649 m). All Fury and Sea Fury aircraft had the same 38 ft 5 in (11.7 m) wingspan. At 34 ft 8 in (10.6 m), the Sabre-powered Fury was 1 in (25.4 mm) longer than the Sea Fury. The Fury I had an empty weight of 9,350 lb (4,241 kg) and a loaded weight of 12,120 lb (5,498 kg).
