This page is about the Italian jet fighter G.91 pre-serie. For similar playstyle, see G.91 R/1 and G.91 (Family).

The G.91 pre-serie (nicknamed "Gina") is a rank V Italian jet fighter with a battle rating of 8.3 (AB/RB/SB). It was introduced in Update 1.69 "Regia Aeronautica" along with the initial Italian aviation tree.

A mid 50's Trans-sonic fighter ( < Mach 0.98) with ground attack abilities. Very maneuverable, but with a light offensive armament makes the G.91 with its young age a difficult starter aircraft into the jet era. Especially as it will fly in fierce competition in the sky, facing every sub- and trans-sonic aircraft and being smack in the middle performance wise.

There are little changes between the Pre-serie, R/1, R/3 and the R/4, and this guide can be considered universal for all listed aircraft.

General info

Flight Performance

The G.91 was intended to replace the F-86A Sabre in German, Portuguese and Italian service and it shows.With an empty weight of only 3100 kg (6800 lbs) and a takeoff weight of 5500 kg (12100 lbs) the Gina is in the weight class as the P-51D and MiG-9, yet severly lighter than most other jets and losing about one and a half tonnes compared to the Sabre A. Although only outputting a meager 22 kN of thrust this first look dosadvantage is literally outweighted by the high thrust to weight ratio of 0.73 empty (0.41 full). This makes the Gina an excellent dogfighter as jet fighters maintain both their top speed, climb and sustained turn-rate by their engine power rather than other flight characteristics. It can easily reach its own terminal speed (1011 km/h, 921 f/s) and self-destruct in level flight.

Lacking in straight wings and leading wing slats the stall speed for the G.91 is quite higher than the low weight lets one assume. One should hence be wary of many older jet types with said features, as after bleeding too much speed they can easily out maneuver the Gina.

Starting with 20 min of fuel, gaining the climb speed of 800 km/h IAS (sustainable @ 7-8°; 730 f/s) takes a mere ~80 seconds with 20 predicated for taking off at 230 km/h or 210 f/s IAS. An Immelmann at 800 km/h will gain 1000 m and loose 300 km/h. A hard 180° turn at the same speed takes >100 km/h and may lose up to 60 m.

Survivability and armour

At its tier there is little which cannot hurt the G.91. This is mostly due to the large calibres and fast firing weapons found in the jet age, although the Gina does not help this issue. The armour is enough to withstand the occasional tank LMG fire, but otherwise will only protect the pilot from shrapnel damage. Even though the centerline arrangement of all components proves to be quite survivable in combat, it does NOT lend itself for head-ons or prolongued chases. The former only leads to functional aircraft with a dead pilot and the latter to the reverse, which was in all likelihood the intended design in real life.

  • 6.5 mm Steel - Behind, below and in front of the pilot
  • 6.5 mm Steel - under central fuel tanks.
  • 40 mm bulletproof glass - Armored windshield
  • Critical components located down the midline of aircraft (fuel, pilot, engine, controls)
  • Fuel tanks located in the central fuselage.


Offensive armament

The M3 Browning is a new weapon in the Italian arsenal at this 5th tier and compared to the previous experiences a let down. The rate of fire is phenomenal, but the small calibre and ammo size put a serious demper to the mood, that is in comparison of course. In practise and with good aim, it can easily shred four fighters. The high bullet velocity and fire rate is quite the advantage in the fast pace world of jet combat, ensuring hits in deflection shots were the lower rate of fire found in the might have failed the pilot. Yet one will always look onto greener pastures, especially as the Gina only has four guns unlike all other Browning armed jets.
No matter how you turn it, the armament is only managable with skill and for a beginner outright bad.

Main article: Browning M3 (12.7 mm)

The G.91 pre-serie is armed with:

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

Suspended armament

Mediocre. The G.91 is a fighter and it shows in the additional payloads. They should only be considered for a quick drop on the way to the combat zone, losing height/speed advantage in doing so, or once aerial dominance has already accomplished. Even then many other jets are way better suited for ground attacks.
The bombs are standard fare and often not worse the hassle with their low total yield. The FFAR rockets are a far better option allowing to tackle more than one target, even though they only work well against soft target and upto medium tanks.

The G.91 pre-serie can be outfitted with the following ordnance:

  • Without load
  • 2 x 500 lb AN-M64A1 bombs (1,000 lb total)
  • 38 x FFAR Mighty Mouse rockets

Usage in battles

Air superiority is the combat objective for the G.91 Gina, anything else is secondary. In team games lure enemy fighters into extensive and excessive dogfights to allow your heavier and less nimble allies to Boom and Zoom or Boom and Run them. With their great thrust to weight ratio the G.91 can maintain their energy superiority and in emergencies (such as non-existant teamplay) to disengage. Alternatively standard BnZ is considerable choice. Again the great acceleration allows for more energy expensive maneuvers and still disengage without much worry from the target. Such follies would be deadly in many other fighters, but the Gina is hence quite forgiving. In fact too forgiving, new pilots to the jet age need to lose old habits and the G.91 does not force one's hand.

Against bombers and ground attack craft the G.91 lacks fire power and it will take considerable ammo use to compensate for this. The measly protection against defensive fire makes this a dangerous task anyway and should thusly be left for better equipped allies.

The very same can be said for ground attacks. While being able to mount air-to-ground ordnance, the payload yield is miniscule. The FFAR pods are the only worthwhile consideration, but run against the G.91's intended role of Air Superiority Fighter.

A focus should be done on the engine modules, as the G.91 lives by its T/W ratio. New boosters is a double edged sword, as without the G-Suit one is just black out earlier. This oddly makes the Bomb unlock a tantalizing choice, especially in already won matches for farming on ground units before the game ends. Airframe and cover do little, the weight savings are very minor and without them the G.91 can still easily reach top speeds and rip off its wings...

Pros and cons


  • Low weight, High thrust to weight ratio
    • Great turn time for a jet; can give the MiG-15 a run for its money
    • Great acceleration and climb rate
  • 4 x M3 machine guns can be deadly if aimed correctly and used in close range


  • Short burst time due to low ammo count
  • Limited ground attack abilities
  • Bleeds off a lot of speed in a full elevator turn
  • Can rip its wings off if you pull full elevator past 800 km/h


Winner of the 1953 NATO light tactical support aircraft competition, the Fiat "Small Sabre" would be in production for 19 years, with 756 aircraft completed, with the last aircraft produced in 1977. It served in the Italian and West German air forces starting in 1961 and 1962 respectively.

The original competition specifications called for a jet able to carry 450 kg of ordnance with an operational radius of 180 km, assuming 10 minutes over the target, with a maximum speed of at least Mach 0.95 and a takeoff distance of no more than 1100m, on unprepared or grass runways. Eight aircraft competed in the first round, including the French Dassault Etendard (then called the Mystere XXVI) and the British Folland Gnat. The Etendard, the G.91 and a Breguet design were selected for the second round beginning in late 1957. Fiat went ahead with pre-production ("pre-serie" in Italian) aircraft, with first flight in August, 1956, seven months ahead of its competitors. The crash of the first prototype due to aeroclastic vibrations in February, 1957, proved a setback, but the G.91 entered the second round as scheduled and was announced as the winner in January, 1958.

Critics said Fiat had just copied the F-86 Sabre, which it was manufacturing under license, but these claims seem unwarranted. Operational service evaluations with the Italian air force's 103 Squadron ran from February to July, 1959, leading to a West German decision to manufacture the aircraft under license.
