The '''{{Specs|name}}''' is a rank {{Specs|rank}} Italian jet fighter {{Battle-rating}}. It was introduced in [[Update 1.87 "Locked On"]].

The {{PAGENAME}} is a multi-role fighter which first debuted in 1966. Based largely on earlier Fiat G.91 fighters, the G.91 YS was a complete redesign but kept the basic shape of the G.91 series. The biggest difference between the two types was the conversion from a single-engine to two General Electric J85 turbojets outfitted with afterburners. This conversion alone resulted in a 60% increase in the aircraft's thrust, however, it was not enough for this jet to become supersonic even when in a dive.

In similar fashion to the earlier French fighter, the [[Super_Mystere_B2|Super Mystere B2]], the {{PAGENAME}} was outfitted with dual 30 mm DEFA autocannons in the cheeks of the forward fuselage. Also in the same vein, the {{PAGENAME}} was built to be a multi-role fighter as a fighter-interceptor or a fighter-bomber. Due to the increased power of the dual engines, this fighter when acting in a bomber role has the ability to carry up to 4,000 lbs of bombs, though configurations as low as 1,000 lbs is available. FFAR Mighty Mouse unguided rockets are another good option for taking out softer ground targets in which the larger 500 – 1,000 lb bombs would otherwise be overkill.

The {{PAGENAME}} while lacking in the supersonic flight department is a feisty little fellow which can still hold its own in an air-to-air combat role. The dual autocannons can make quick work of any head-on attacks provided the pilot gets out of the way of incoming bullets in return. AIM-9B Sidewinder missiles prove themselves very effective especially against slower targets such as bombers and helicopters but are a bit more difficult to achieve success against other fighters due to their ability to pull high-g manoeuvres and break the missile lock and avoid them.

The pilot has the option to change up the load-out of the aircraft due to the map he finds himself on and what they are comfortable with. Air-to-air and ground-attack options are both viable and can help change the tide of the battle by loading up on what the team needs more.

== General info ==
=== Flight performance ===

The {{PAGENAME}} 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 ===


* 40 mm bulletproof glass in the canopy windshield (angled to provide about 94 mm of protection)
* 6.5 mm steel behind pilot's seat

Like many later generation jet fighters (those built in the 1960s-70s) the {{PAGENAME}} traded armour for greater ordnance carrying capacity. Though not without all armour, the canopy windshield has an effective thickness of 94 mm to protect the pilot in the event of a head-on attack. Though the 6.5 mm of steel behind the pilot's seat seem to be on the thin side, bullets coming in from that direction will need to pass through the engine first. If the pilot is going to be hit by bullets it will most likely be through side angle shots or from above.

=== Offensive armament ===

{{main|DEFA 552 (30 mm)}}
[[File:G91YS CrazyJow 001.jpg|400px|thumb|right|'''{{PAGENAME}}''' fighter with the sun setting behind it.]]

The '''''{{PAGENAME}}''''' is armed with:

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

=== Suspended armament ===

{{main|LDGP Mk 82 (500 lb)|LDGP Mk 83 (1,000 lb)|FFAR Mighty Mouse|AIM-9B}}

The '''''{{PAGENAME}}''''' 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 {{PAGENAME}}. 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 {{PAGENAME}}.

=== Pros and cons ===

[[File:G91YS easterly0815 001.png |400px|thumb|right|'''{{PAGENAME}}''' popping its breaking parachute upon landing.]]
'''Pros:'''

* Excellent acceleration and roll speed
* Able to carry [[AIM-9B]] air-to-air missiles
* Wide variety of payload options
* High rate of climb
* Deadly main armament
* Drag Chute helps slow you down very quickly

'''Cons'''

* Slower than most planes it will face
* Limited ammo
* Slower turn rate compared to earlier G.91's
* High repair cost
* Flaps and landing gear are prone to ripping off
* New booster module is a must to research in order to avoid crashing during a very fast and low-level dive

== History ==

[[File:G91YS Jermster 91 002.jpg|400px|thumb|right|'''{{PAGENAME}}''' heading into an active battle zone.]]
During the 1960s, Fiat began developing a successor to their previous G.91 fighter, which had thus far managed to obtain a favourable 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 accommodate 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.

{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Italian jet fighter {{Battle-rating}}. It was introduced in [[Update 1.87 "Locked On"]].

The {{PAGENAME}} is a multi-role fighter which first debuted in 1966. Based largely on earlier Fiat G.91 fighters, the G.91 YS was a complete redesign but kept the basic shape of the G.91 series. The biggest difference between the two types was the conversion from a single-engine to two General Electric J85 turbojets outfitted with afterburners. This conversion alone resulted in a 60% increase in the aircraft’s thrust, however, it was not enough for this jet to become supersonic even when in a dive.

In similar fashion to the earlier French fighter, the [[Super_Mystere_B2|Super Mystere B2]], the {{PAGENAME}} was outfitted with dual 30 mm DEFA autocannons in the cheeks of the forward fuselage. Also in the same vein, the {{PAGENAME}} was built to be a multi-role fighter as a fighter-interceptor or a fighter-bomber. Due to the increased power of the dual engines, this fighter when acting in a bomber role has the ability to carry up to 4,000 lbs of bombs, though configurations as low as 1,000 lbs is available. FFAR Mighty Mouse unguided rockets are another good option for taking out softer ground targets in which the larger 500 – 1,000 lb bombs would otherwise be overkill.

The {{PAGENAME}} while lacking in the supersonic flight department is a feisty little fellow which can still hold its own in an air-to-air combat role. The dual autocannons can make quick work of any head-on attacks provided the pilot gets out of the way of incoming bullets in return. AIM-9B Sidewinder missiles prove themselves very effective especially against slower targets such as bombers and helicopters but are a bit more difficult to achieve success against other fighters due to their ability to pull high-g manoeuvres and break the missile lock and avoid them.

The pilot has the option to change up the load-out of the aircraft due to the map he finds himself on and what they are comfortable with. Air-to-air and ground-attack options are both viable and can help change the tide of the battle by loading up on what the team needs more.
== General info ==
=== Flight Performance ===

The {{PAGENAME}} 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 ===


* 40 mm bulletproof glass in the canopy windshield (angled to provide about 94 mm of protection)
* 6.5 mm steel behind pilot's seat

Like many later generation jet fighters (those built in the 1960s-70s) the {{PAGENAME}} traded armour for greater ordnance carrying capacity. Though not without all armour, the canopy windshield has an effective thickness of 94 mm to protect the pilot in the event of a head-on attack. Though the 6.5 mm of steel behind the pilot's seat seem to be on the thin side, bullets coming in from that direction will need to pass through the engine first. If the pilot is going to be hit by bullets it will most likely be through side angle shots or from above.

[[File:G91YS CrazyJow 001.jpg|400px|thumb|right|'''{{PAGENAME}}''' fighter with the sun setting behind it.]]
The '''''{{PAGENAME}}''''' is armed with:

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

=== Suspended armament ===

{{main|LDGP Mk 82 (500 lb)|LDGP Mk 83 (1,000 lb)|FFAR Mighty Mouse|AIM-9B}}

The '''''{{PAGENAME}}''''' 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 {{PAGENAME}}. 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 {{PAGENAME}}.

== History ==

[[File:G91YS Jermster 91 002.jpg|400px|thumb|right|'''{{PAGENAME}}''' heading into an active battle zone.]]
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.

{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} British fighter {{Battle-rating}}. This aircraft has been in the game since the start of the Open Beta Test prior to Update 1.27.

The Typhoon is a heavily armed, fast fighter bomber which excels in Boom and Zoom tactics. It is armed with four deadly Hispano cannons, which can obliterate enemy fighters with the air targets belt. With all modules purchased, the Typhoon is one of the fastest planes in its tier, reaching speeds of almost 700km/h in level flight. You also have an excellent climb rate and great manoeuvrability, enabling you to dogfight quite effectively against some targets.

You also get some decent payload options. A choice of 2 x 250, 500 or 1000 lb bombs or 8 x RP-3 rockets allow you to hit enemy ground targets hard and fast. Just beware that carrying such payloads will adversely affect your flight characteristics. In realistic battles ground forces, it is best to assess the situation on the battlefield. If the enemy team is ground forces heavy, you can choose to thin them out with bombs or rockets. You can even use your cannons to good effect on light targets like the Wirbelwind and PT-76. If the enemy team has a high volume of aircraft in the air, leave the payload and just focus on taking them out.

=== In-game description ===

The Hawker Typhoon was the planned successor to the Hurricane, as a support high altitude fighter for the Spitfire. However early problems with its structural integrity cause it to commonly break its back on landing. The engine was also far from perfect. The Napier Sabre was very temperamental and often combusted into flames when started. The large prop was also an issue. The diameter was one of the biggest of the war and a prop strike would almost always flip the aircraft. Another problem was the thick wings the Typhoon used. They performed poorly at its intended high altitude and the plane was quickly moved to a low altitude ground attack role. Here it found its element. The Typhoon's thick wings allowed it to carry 4 20mm cannons and up to a 2000lb bomb load. The "Tiffie" became one of the best RAF ground attack aircraft of the war and was praised for its stable gun platform and durability. The Typhoon was succeeded by the Tempest, which improved and fixed the earlier design.

The Hawker Typhoon was a single engine, single seat fighter which first entered service with the RAF in 1941. Typhoon fighters of the first production series were equipped with a canopy with massive framing and a Rover-produced car-type side door for cockpit access. The first modification of this was to replace some of the solid metal fairings with transparent panels and cut down the pilot’s head armor plate to help increase visibility. Lack of visibility remained a significant problem and whilst a new canopy was being developed, the bulky radio mast and its fairing were replaced with a whip aerial further aft along the fuselage. A new drop-shaped canopy was designed for the pilot's cockpit, providing a good all-round view. The new canopies were fitted on the production aircraft from September 1943 on.

The fighters were equipped with more powerful 2,200 hp Napier Sabre Mk.IIB and 2,260 hp Napier Sabre Mk.IIC engines, as well as new four-bladed de Havilland propellers. The wing-mounted armament consisted of four 20 mm British Hispano Mk.II belt-fed cannons with 140 rounds per gun. The projecting cannon barrels were equipped with fairings to reduce drag.

By the end of 1943, these improvements had been implemented on the majority of the Typhoons already in service.

By the time these later Mk IBs were in service, the aircraft’s shortcomings as a fighter had been identified, but it coped perfectly in the role of a fighter-bomber and a close air-support aircraft, striking German airfields, communication lines, railways, and ships.

Since Typhoons were flown at low altitudes under strong enemy anti-aircraft fire, the designers paid great attention to protecting the pilot and the aircraft's vital systems. The pilot's head and back were protected with an armored backrest and a 38 mm thick armored glass windscreen. An armor plate protecting the engine was fitted behind the propeller fairing.

After many early teething problems, critical failures and threats to be withdrawn from service altogether, the Typhoon finally found its niche as a rugged, dependable ground attack aircraft. It achieved notoriety amongst German soldiers during the Normandy campaign when, whilst Spitfires were achieving air superiority, the Typhoons were able to cause mayhem amongst German ground units. The Typhoon's production was discontinued in November 1945, and it was withdrawn from service in early 1947. All in all, 3,205 Hawker Typhoon Mk.IB aircraft were produced.

== History ==
''The CAC Boomerang was an Australian single-seat, single-engine fighter of mixed wood and aluminium construction.''

''The Japanese attack on Pearl Harbour on December 7, 1941 and subsequent event in the pacific theatre of operations showed how unprepared the Australians were for war. The country had fewer than two hundred military aircraft, most of them obsolete. At that time, the Commonwealth Aircraft Corporation (CAC) only produced trainers, the CAC wirraway (a licensed version of the american NA-33) The License Agreement Provided for modifications, so, in order to have an fighter aircraft as soon as possible, The CAC decided to use the the trainer as a basis for a new fighter.''

''The CA-12(later called the Boomerang Mk.1) was created, the first domestically produced fighter to ever roll off Australian assembly lines. The CA-12 borrowed the Wirraway's landing gear, tail, and wing design and was powered by a license built American Pratt and Whitney Twin Wasp engine, rated at 1200 hp. The aircraft was armed with two Hispano cannons and four 0.303 inch Browning machine guns and could carny four 9kg smoke bombs to mark targets, one 337kg bomb, or a 365 liter external fuel tank.''

''The Ca-12 had high durability, good armament, and excellent handling characteristics at low level, although this performance deteriorated at height and the fighter's top speed was not at all competitive.''

''Mass production began in July 1942 and 105 Boomerang Mk.1 fighter were produced.''

G.91 YS

U48762717: /* Details */

{{Specs-Card|code=fiat_g91_ys}}
{{About
| about = Italian jet fighter '''{{PAGENAME}}'''
| usage = other uses
| link = G.91 (Family)
}}

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Italian jet fighter {{Battle-rating}}. It was introduced in [[Update 1.87 "Locked On"]].

== General info ==
=== Flight Performance ===

The {{PAGENAME}} 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 ===

{{main|DEFA 552 (30 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

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

=== Suspended armament ===

{{main|LDGP Mk 82 (500 lb)|LDGP Mk 83 (1,000 lb)|FFAR Mighty Mouse|AIM-9B}}

The '''''{{PAGENAME}}''''' 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 {{PAGENAME}}. 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 {{PAGENAME}}.

=== 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.
