In early 1944, Alexander Kartveli, the chief designer for the Republic Aviation Aircraft Company set out to work on a replacement for the piston-powered P-47 Thunderbolt which instead would be powered by a turbojet. All attempts at trying to use the P-47 frame to accommodate a turbojet failed and Kartveli resorted to designing a brand new aircraft around an axial compressor turbojet engine. Due to the nature of the engine taking up a large majority of the fuselage, fuel tanks were designed to be in the wings of the aircraft, however, the body was streamlined to make the smallest profile possible and retain all necessary critical components.

The USAAF in September 1944 released new requirements for a daytime fighter along with specific characteristics such as the top speed of 600 mph (966 kph), armament of six 21.7mm machine guns or four 15.2 mm machine guns along with housing a General Electric TG-180 axial turbojet also known as the Allison J35 series turbojet engine. Republic proposed their new aircraft and on paper proposed it would be superior to Lockheed’s P-80 Shooting Star. The USAAF noting Republic’s already proven experience with single-seat fighters proposed a contract without holding any competition. These initial order fighters were listed as YP-84As and P-84Bs.

These early test aircraft were put to wind tunnel testing and it was found that major flaws developed when subjected to high speeds, notably longitudinal instability in the aircraft’s frame and stabilizer skin buckling at high speeds. Also noted was issues with the weight of the aircraft and the problem with early turbojets not producing enough thrust for takeoff and climb outs (a problem which plagued the F-84B aircraft until more robust engines were outfitted). Early J35-GE-7 engines were replaced with J35-A-15 versions which helped with the thrust ratio, however wing-tip fuel tanks were added to the mix prior to proper testing and issues developed which at one point grounded the fleet of aircraft until modifications were made.

In 1947, the USAF changed the pursuit designation of the aircraft to fighter and thus the P-84 became the F-84. The YP-84A and the F-84B only differed when it came to the type of M3 machine guns they carried, as the F-84B had faster-firing machine guns than the YP-84A. Early successes of the F-84B were overshadowed by problem after problem including a speed restriction limiting flight to no more than Mach 0.8 as any faster and the aircraft experienced control reversal where the pilot would input normal commands with the control stick and the opposite manoeuvre would occur (for instance if the pilot pulled back on the control stick to make the aircraft climb, the aircraft would actually begin to dive and vice versa). Even with the speed restrictions, the entire fleet of F-84B fighters was grounded by 1948 due to parts shortages and structural failures. It was also at this time that the F-84C aircraft were also determined to be incapable of performing any of their mission parameters, however since the F-84D was already under production (with all of the B and C variants issues being resolved), the program continued. Funding was allocated to upgrade the B and C variants, however, both were finally withdrawn from active duty service by the end of 1952.

Testing of the F-84D determined that the wings needed to be covered with a thicker aluminium skin to strengthen them which was helpful because the engine was upgraded to the more powerful J35-A-17D. Here it was found that during high-G manoeuvres, the wingtip fuel tanks led to the structural failure of the wings due to twisting motions. A simple fix of adding a small triangular fin to the external portion of the fuel tank alleviated that problem. Despite the fixes introduced with the D variant, it too was withdrawn from active duty in 1952.

The F-84E variant fighter saw modifications specifically with strengthened wings and a larger cockpit which was necessary to equip advanced avionics to include an A-1C gunsight which worked with an APG-30 radar. Folding rocket racks were also developed so that once the HVAR rockets were fired; the racks would fold flush with the wing increasing the aircraft’s overall aerodynamics. Unfortunately even with all of the modifications, failure of the aircraft hinged upon the Allison J35-A-17 engines which were only designed to be flown for 25 hours a month and would receive a complete overhaul after 100 hours of flight. Due to the number of sorties flown in the Korean War, engine overhauls were taking place more frequently and quickly exhausted all of the spare parts and new engines produced.

Description

GarageImage F-84G-21-RE (Italy).jpg


The ▄F-84G-21-RE Thunderjet is a rank V Italian jet fighter with a battle rating of 7.7 (AB/RB) and 8.0 (SB). It was introduced in Update 1.69 "Regia Aeronautica".

The F-84G is a fighter-bomber. It's very capable at fighting enemy aircraft while also quite good at CAS (close air support).

The F-84G's acceleration is quite good for a jet at with a battle rating of 7.7 (AB/RB) and 8.0 (SB). It's also a very good climber, precisely the early jet with the best climb rate. It has got 6 x 12.7mm M3 machine guns with 1800 rounds of ammunition which is plenty. The air spawn at 610-640 kph is a huge advantage. Turn rate is poor, avoid turn fighting in it. Roll rate is average without New Boosters, good with New Boosters.

The F-84G-21-RE is a Boom & Zoom aircraft. It utilizes its ability to rush thanks to the air spawn, acceleration and very good climb rate in order to cause the enemies to panic.

Armaments

Offensive armament

Main article: Browning M3 (12.7 mm)

The F-84G-21-RE (Italy) is armed with:

  • 4 x 12.7 mm Browning M3 machine guns, nose-mounted (300 rpg = 1,200 total)
  • 2 x 12.7 mm Browning M3 machine guns, wing-mounted (300 rpg = 600 total)

Suspended armament

Main articles: HVAR, Tiny Tim

The F-84G-21-RE (Italy) can be outfitted with the following ordinance:

  • 2 x 100 lb AN-M30A1 bombs (200 lb total)
  • 2 x 250 lb AN-M57 bombs (500 lb total)
  • 2 x 500 lb AN-M64A1 bombs (1,000 lb total)
  • 2 x 1,000 lb AN-M65A1 bombs (2,000 lb total)
  • 24 x HVAR rockets
  • 32 x HVAR rockets
  • 24 x HVAR rockets + 2 x 100 lb AN-M30A1 bombs (200 lb total)
  • 24 x HVAR rockets + 2 x 250 lb AN-M57 bombs (500 lb total)
  • 24 x HVAR rockets + 2 x 500 lb AN-M64A1 bombs (1,000 lb total)
  • 24 x HVAR rockets + 2 x 1,000 lb AN-M65A1 bombs (2,000 lb total)
  • 24 x HVAR rockets + 2 x Tiny Tim rockets

Usage in the battles

The F-84G-21-RE should be played as an aggressive Boom & Zoom aircraft. Meaning that as soon as you spawn in it, you turn to the direction of the enemy airfield to rush and reach 850+ kph. Engage those who are climbing, there is also a chance of catching a few away-from-keyboard climbers too. After climbing to engage an enemy at altitude, do not turn back to follow them if they evade. Continue zoom climbing, do a vertical loop and maintain level flight to gain a little bit more speed. After that, the only way you're supposed to fly against enemies is by diving, engaging, zooming up, vertical loop then rinse and repeat.
