Description

The G.91 YS is a rank VI Italian jet fighter with a battle rating of 9.7 (AB/SB) and 9.3 (RB). It was introduced in Update 1.87 "Locked On".

General info

Flight Performance

The G.91 YS is a very good Boom & Zoom fighter, the only issue is confronting other jets with afterburner capabilities which make your Boom & Zoom attempt more difficult. The G.91 has a lower turn speed than the other G.91's (swapped for acceleration and a little bit more speed) it is also two high power engine's, making it possible to return to base on one engine or even fight like that if you want. Sadly the G.91 isn't supersonic but it can get close in a steep dive, making it one of the best trans-sonic jets ever made!

Survivability and armour

The YS is a single-seater fighter making it venerable to head-on attacks even though the YS has 40 mm of bulletproof glass in the canopy windshield, which at an angle provides ~94 mm of protection. Behind the pilot's seat is 6.5 mm of armour, though it is weak to rear attack if the enemy misses your engine.

Armaments

Offensive armament

The G.91 YS is armed with:

• 2 x 30 mm DEFA 552 cannons, nose-mounted (125 rpg = 250 total)

Suspended armament

The G.91 YS can be outfitted with the following ordnance:

• Without load
• 2 x 500 lb LDGP Mk 82 bombs (1,000 lb total)
• 4 x 500 lb LDGP Mk 82 bombs (2,000 lb total)
• 2 x 1,000 lb LDGP Mk 83 bombs (2,000 lb total)
• 4 x 1,000 lb LDGP Mk 83 bombs (4,000 lb total)
• 76 x FFAR Mighty Mouse rockets
• 2 x AIM-9B missiles
• 2 x 500 lb LDGP Mk 82 bombs + 2 x AIM-9B missiles (1,000 lb total)
• 4 x 500 lb LDGP Mk 82 bombs + 2 x AIM-9B missiles (2,000 lb total)
• 2 x 1,000 lb LDGP Mk 83 bombs + 2 x AIM-9B missiles (2,000 lb total)
• 4 x 1,000 lb LDGP Mk 83 bombs + 2 x AIM-9B missiles (4,000 lb total)
• 2 x AIM-9B missiles + 76 x FFAR Mighty Mouse rockets

Usage in battles

The YS has a lot of power and energy potential, keep that in mind before going into battle. To add to this fighters punch, it also utilises AIM 9B missiles and in capable hands, this fighter can be a monster on the battlefield. The YS also has the capability of mounting 76 x FFAR Mighty Mouse rockets which provide the potential of low-altitude Boom & Zooming on trucks, anti-aircraft artillery, light tanks and even enemy fighters attempting an airfield capture, though this does not come without a cost. When dropping in low on ground targets, the fighter sacrifices its speed and manoeuvrability for that ordinance. The YS also can outfit a few bombs so the YS can then be used as a base bomber following up by attacking enemy fighters, but even still it isn't always reliable and can be easily intercepted from any other supersonic fighter jets patrolling the area.

Your biggest threats will be F-4C's, Mig 19S/PT, F-100D, Mitsubishi T2, J-6A, J-7II, Hunter F.6, mainly because they have superior speed and ordinance, The Hunter is probably the best-matched jet to the G.91 YS. The only top tier jet which should not be too much of a pain is the Super Mystere B2, and F-86K because they have limited speed and slow acceleration compared and will never win in a vertical climb against the G.91 YS.

Pros and cons

Pros:

• Has extreme acceleration and good roll speed
• Devastating AIM-9 Sidewinder missiles
• Wide variety of payload options
• Decently fast
• Two 30 mm DEFA cannons cause more damage than the original 4 x M3 Browning machine guns

Cons:

• Nearly every foe at its rank (ex. F-100D, MiG-19) is faster
• Fairly low ammo count for the guns (requires trigger control)
• Slower turn speed than the other G.91 Counterparts
• Other G.91 YS's can do the same thing as all those plus's

History

During the 1960s, Fiat began developing a successor to their previous G.91 fighter, which had thus far managed to obtain a favorable reputation with its operators. Fiat based their new aircraft heavily on the two-seat trainer version of the G.91 and decided outfit the aircraft with two General Electric J85 afterburning engines contrary to the preceding single-engine G.91.

Additionally, the aircraft’s fuselage and wings were enlarged to accomodate for the bigger powerplant and improve handling characteristics, while a slew of other tweaks and upgrades further enhanced the aircraft’s overall design. The new G.91Y performed its maiden flight in December 1966. Testing revealed minor aerodynamic issues which would be resolved on subsequent production aircraft with only minor redesigns.

Production of the G.91Y began with an initial order for 20 pre-production machines, following the manufacturing of two prototypes. This order would eventually go up to 75 aircraft, although only 67 including the initial prototypes were delivered in the end. By the mid 1970s, all outstanding orders for the G.91Y were fulfilled and production had ceased for this variant.

The G.91Y served exclusively with Italian squadrons up until the early 1990s, before being replaced by a more modern counterpart.

The G.91YS was a single prototype conversion of the G.91Y, which followed a requirement issued by the Swiss Air Force. The aircraft allowed installation of American Sidewinder air-to-air missiles, and a Swedish weapons control system. This special prototype first flew in October 1970, but was eventually not accepted into service by the Swiss. The prototype was converted back into service as a regular G.91Y.
