Survivability and armour
Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.

Usage in battles
Describe the tactics of playing in an aircraft, the features of using vehicles in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons
Pros:
- Great turn speed for a jet; on par with the MiG-15 in this area.
- Can equip 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 means that you need to be conservative with your ammo.
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.
