Description

The G.91 R/4 is a gift rank V Italian jet fighter with a battle rating of 8.3 (AB), 8.7 (RB), and 9.0 (SB). It was introduced in Update 1.87 "Locked On".

General info

Flight Performance

The G.91 R/4 is a very nimble fighter with relatively average top speed and fairly good acceleration. Best played as a support fighter, the G.91 R/4 can use its incredible roll and turn rates to quickly get guns on target, as well as to dodge the typically less manoeuvrable fighters that it shares its battle ratings with.

The R/4 is a variant of the G.91 jet fighter that has been modified for ground attack, allowing it access to a competitive selection of air-to-ground ordnance such as bombs, rockets, and high-explosive air-to-ground missiles. The R/4 also has the option to equip two different types of air-to-air missiles; the IR-tracking AIM-9B Sidewinder missile, or the command-guided AA-20 Nord missile.

Survivability and armour

• 40 mm Bulletproof glass in front of the pilot
• 6.5 mm Steel plate, starts in the pilot's seat, goes below the pilot, ends in front of the pilot
• 6.5 mm Steel plate below a fuel tank in the centre-front of the fuselage
• 6.5 mm Steel plate below a fuel tank in the centre-rear of the fuselage

Though the G.91 R/4 does have a decent amount of armour spaced out between the centre and front of the fuselage, the Steel plates will only be sufficient to protect the pilot and aircraft from lower calibre fire (7.92 mm to 7.62 mm machine guns will only penetrate at very close ranges.) And, thanks to the sacrifices made to lighten the aircraft, the airframe is not particularly reinforced. The wings are very thin, and susceptible to being out-right broken off by most-all primary armaments the G.91 will face at its tier, and the fuselage is full of juicy fuel tanks as well as the single engine of the R/4. Even more so than most planes, the G.91 R/4 is not capable of taking any hits. Even low calibre fire, such as that from .50 calibre machine guns, can cripple an R/4 nigh-immediately, and necessitate an immediate return-to-base.

Armaments

Offensive armament

The G.91 R/4 is armed with:

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

Suspended armament

The G.91 R/4 can be outfitted with the following ordnance:

• Without load
• 38 x FFAR Mighty Mouse rockets
• 2 x AA-20 missiles
• 2 x AS-20 rockets
• 4 x AIM-9B missiles
• 2 x 500 lb AN-M64A1 bombs (1,000 lb total)

For air-to-ground purposes, the G.91 R/4 is similar to the G.91 pre-serie and G.91 R/1, both its predecessors, in loadout options sharing the same FFAR Mighty Mouse rocket option as well as the choice of a pair of 500 lb bombs. However, the G.91 R/4 has an additional and unique option; the AS-20 Nord air-to-ground missile, with a reasonable penetration value (83 mm RHAe) but incredible warhead size of (just under) 30 kilograms of TNT. Skilled use of the missile can allow for a more accurate fire at longer ranges especially versus more dangerous vehicles like self-propelled anti-aircraft guns.

Air-to-air ordnance selection is where the G.91 R/4 stands out from its brethren; the G.91 R/4 is the lowest tier jet in the Italian aircraft tree to gain access to air-to-air missiles, with access to the American AIM-9B infrared-guided missile, and one of only two jets in-game (alongside the Super Mystére B.2) to have the option of loading the unique AA-20 Nord air-to-air missiles; keyboard guided missiles with a 15 metre proximity fuse. Unlike infrared-guided missiles in War Thunder, the AA-20 Nords do not warn targets of a missile launch giving R/4 pilots the element of surprise, and the Nord's proximity fuse increases the chance of long-range launches striking a target, though these perks come at the demand of a much higher skill floor for usage.

Usage in battles

Due to the G.91 R/4's notably lower speed and high-end acceleration as compared to its contemporaries, the R/4 should be played as a support fighter; meaning the pilot should seek to stick near teammates rather than hunting targets solo, and opt to pick off hostile aircraft that are engaged and distracted with/by allied fighters. The G.91 airframe is exceptionally agile, and the R/4 is no exception; even heavily manoeuvring targets are easy for this plane to keep the nose on. The plane's exceptional roll and turn rates are its biggest strengths, and the pilot should seek to use that to their advantage rather than attempting to fight speed or energy battles.

Make use of the G.91 R/4's varied suspended armaments to dispatch a variety of targets. The AIM-9B is very easy to use missile and can force faster targets to manoeuvre, slowing them down, and can sometimes even net target destructions. Be careful when using this missile around friendlies though, as a misguided Sidewinder will destroy allied aircraft. The AA-20 Nord is a much more difficult missile to use, but it has a far longer effective range and can often surprise enemies who expect a warning from enemy missile launches. Use the massive range and proximity fuse to take down faster targets flying away from you, and consider using them to destroy bombers such as the often-seen Vautour IIB, Vautour IIA, and Israeli Vautour IIA, who not only are far less able to dodge missiles but also have larger airframes that trigger the proximity fuse from longer distances.
