Description
One of the many complaints from pilots flying the machine gun armed F-86 Sabre was the lack of the hard-hitting punch delivered by cannons. MiG-15s would routinely be hit by machine gun rounds only to shrug it off. Ten F-86s were selected to utilize the T-160 20-mm cannon. They had an impressive fire rate of 1,500 rounds per minute which was both a blessing and a curse. The T-160s had an abysmal amount of trigger time but the high fire rate could also easily take down planes with a tiny burst if aimed properly. Later named Project Gunval, tests continued and no problems were discovered until combat. Eight Gunvals were transferred to Korea and Gunval pilots soon discovered a giant issue. The gas from firing the cannons would be ingested through the air intake and cause engine flameouts. The Gunval Sabres were grounded shortly after until the problem was remedied. The cannon-armed Sabre idea would live on in the F-86H in the form of M39 cannons.
Introduced in Update 1.35, the F-86F-2 Sabre is a sleek jet fighter with very potent armament. The four T-160 cannons mounted in the nose are extremely effective against enemy aircraft. Even a short burst will be enough to quickly take down a fighter but comes with a caveat; the high fire rate also means the cannons eat through ammunition extremely quickly. The F-86F-2 has only 115 rounds per gun which is not much since the T-160 cannon has a fire rate of 1,500 rounds per minute.

Usage in battles
20 mm T-160 Revolver Cannons
The plane's biggest strength and its specialty are the four 20 mm T-160 revolver cannons it carries. If you weren’t a fan of Sabres due to its Browning machine guns, know that these guns completely change the feel of the plane. That is because these guns are arguably the best aircraft cannon found at 9.0, boasting extremely high velocity, great damage and great fire rate. On top of that, the Sabre’s airframe makes aiming and leading these excellent guns very easy. None of the F-2 Sabre’s contemporaries can boast such a powerful and easy to utilize gun platform. What this means is that the F-2 Sabre is an excellent plane for punishing other players' mistakes, no matter how small, as just one very quick burst from these guns will devastate most aircraft.
However, there are two downsides about these cannons. The first is that each 20 mm cannon only has 115 rounds of ammo, and with its very fast rate of fire, this ammo capacity will be gone very quickly. The second is that they overheat very quickly; even with the “New 20 mm Cannons” modification, just two to three seconds of sustained firing will cause them to jam. These downsides mean that these cannons demand heavy trigger patience. If you're struggling with ammo conservation, focus on lining up your shots and firing a short burst of 10-15 rounds accurately at a target rather than hosing half your ammo load for a small chance of a critical hit. Something to note is that, to conserve ammo, one may choose to only fire two of the cannons at once (as one set of cannons are considered “machine guns” and the others cannons, they can be selected separately by using weapons selection mode). While the firepower is halved, it is still generally enough to cripple most aircraft with a short burst, so if you find yourself low on ammo and needing more firing time, only firing two cannons at once may be the trick.
Compared to the M3 Browning machine guns that it replaces, the 20 mm T-160 cannons similarly have high velocity and accuracy, and somewhat similar fire rates (the T-160’s is 25% faster than the M3’s). On the other hand, the rest of their characteristics are complete opposites; the T-160 completely gives up the large ammunition capacity and long overheating time of the M3 Browning for greatly increased explosive firepower.
Overall, these guns are excellent, and as long as you have good trigger discipline, they will be very kind to you.
Air Realistic Battles
In Air RB, speed is life, and doubly so for sabres. First thing that should be done after takeoff is gaining at least 1,000 km/h IAS in level flight and assessing the match. If in a downtier, staying on the deck is advisable as you will be one of the fastest planes in the battle. Focus on anyone who can match or exceed your speed and then move on to everyone else once there are no other threats. In an uptier, gain 1-2 km of altitude and play an assassin type role. Make it your mission to kill out of position players while using the threat of your cannon’s knock-out potential to dissuade enemies from attacking you and nearby teammates. Maintaining a decent amount of speed is very important because of the Sabre's comparatively poor handling at lower speed compared to MiGs, G.91s, and the like. While you can certainly effectively dogfight in the Sabre, in furballs you can easily get ganged up on and destroyed, so attempt to avoid doing so unless necessary.
F-2 pilots should always be on the offensive whenever possible to take advantage of the plane's huge impact on the battlefield. By continually maintaining a high energy state, eliminating out of position targets, the F-2 can dominate entire lobbies even in full uptiers.
Radars
The F-86F-2 is equipped with an AN/APG-30 rangefinding radar, located in the nose of the aircraft. It will automatically detect other planes within the scanning area and display the range to the closest target. It is linked with a gyro gunsight and can help with aiming at close range.

History
The "Gun Val" Project
As is well-known, most F-86 Sabre fighters of the USAF that joined the Korean War had six AN/M3 12.7 mm machine guns as their basic weapon configuration against enemy aircraft. Although the experience of the European battlefield during World War II showed that an average of 300 12.7 mm bullets could shoot down an enemy aircraft, the US pilots found that sometimes their 12.7 mm machine guns couldn't easily shoot down enemy MiG fighters even when they scored many hits on them. Though there were also many F-86 fighters that successfully returned to the airfield when they were hit by the 23 mm or 37 mm cannon of the MiG-15 fighter, there was no doubt that the USAF needed a new airborne weapon to replace the aged 12.7 mm machine gun.
Although the USAF had successfully introduced the M24A1 20 mm cannon, the Air Force's version of the Navy's AN/M3 20 mm cannon, on the Convair B-36 Peacemaker strategic bomber, they don't want to simply introduce the old 20 mm cannon to the F-86F Sabre fighter because its rate of fire (700-800 rounds per minute) was found unsuitable for modern air combat. Therefore, a research project named "Gun Val" was established on April 3rd 1951 to find out the most suitable cannon which could be incorporated into current Sabre fighter and the incoming Century Series aircraft. (Other aircraft such as F-94B, F-84F, and F-89C also participated in the Gun Val program).
North American Aviation Company delivered four F-86E-10 and six F-86F-1 Sabre fighters to Air Material Command to test the newly developed T-160 20×102 mm cannon. The T-160 cannon was a single-barreled revolver cannon which was an imitation of the captured German MG213C 20 mm revolver cannon, the latter had been transported to the USA in 1946. Thanks to the cooperation of Springfield Arsenal and the Illinois Institute of Technology, the initial development work of the T-160 cannon was finished in the early 1950s, and it was put into the production line in June 1951. It was a gas-operated, belt-fed, electrically fired weapon, the cannon was capable of firing electrically primed ammunition at a rate of 1,500 rounds per minute and developed a muzzle velocity of 3,250 feet per second. There were five types of 20×102 mm cartridges available for the T-160 cannon, including M55A1 and M55A2 ball, M53 Armour-piercing Incendiary and M56 High-Explosive Incendiary ammunition.
Another cannon joining the competition with the T-160 cannon was the Oerlikon 206 RK 20 mm cannon which was also a revolver gun, capable of firing electrically primed ammunition at the rate of 1,650 rounds per minute and a muzzle velocity of 3,500 feet per second which were both higher than T-160 cannon.
The 10 Sabre fighters fitted with four T-160 cannons were called F-86F-2 while two Sabre fighters with four Oerlikon 206 RK cannons were called F-86F-3. As for the F-86F-3, the USAF didn't receive any of them until April 1954, and the final test report, finished in February 1955, outlined that the Oerlikon 206 RK cannon had lots of problems that needed to be solved before it entered into service, such as poor round dispersion of the gun and installation problems. Though the company claimed that these problems could be solved in the future, at that time the M39 revolver cannon had been put into mass production many years ago, so not surprisingly that the Oerlikon program was canceled in the end.
As a comparison, those ten F-86F-2 fighters equipped with T-160 cannon were much luckier. Apart from the cannon, all F-86F-2 fighters were fitted with new 6-3 wing, and both the original A-4 gun/rocket/bomb calculating sight and the AN/APG-30 ranging radar remained. After the initial test was done, Lieutenant Colonel Peterson who was the project officer of Gun Val program at that time decided to take eight F-86F-2 fighters to Korea aboard the USS Windham Bay for combat trials in December 1952.
All the F-86F-2 fighters were assigned to the 335th FIS of 4th Fighter Wing at Kimpo, and only six aircraft were ever actually in Korea at any one time. When they arrived at Kimpo, these F-86F-2 fighters were re-painted as other original F-86F Sabre fighter such as the black and yellow FEAF ID bands and yellow and black tail stripe. Ground crews also painted the third gun port on the nose under the two 20 mm muzzle to make them looks indistinguishable with the original machine gun-armed F-86F Sabre fighter. Apart from that, the commander of F-86F-2 team was changed to Colonel Garrison, but Peterson was still stayed there as a contractor technician with other three contractor technicians and five assigned pilots.
The combat trial began in January 1953, though it was discovered that the cannon gas from the 20 mm cannon may cause a compressor stall which was very dangerous for both plane and its pilot, including one accident when Major Moorehead fired his 20 mm cannon in a long burst during one mission and caused the engine stop working, though he was able to restart the engine, the problem appeared again later. But even with the Sabre pilots only using two cannons at a time to avoid the problem, they still fired almost 10,900 rounds in combat, engaged MiG fighters in 41 missions and successfully shot down six of them (3 MiG fighters were probably destroyed and 13 MiG fighters damaged) with two F-86F-2 were damaged (one's intake was hit by the 37 mm shell and another one's wing was hit by the 23 mm shell), but unfortunately Captain Moore's plane suffered a flame-out accident followed by turbine failure on 30th April 1953, so he had to bail out in the end.
To solve these problems, Peterson not only sent the report to the test center, but also found a way to simply solve the problem: a simple horseshoe clip installed in the blast tube of the cannon broke up the cannon gas before it could enter the intake. The Gun Val combat trial program was finished on May 1953, and in order to completely solve the cannon gas problem, the engineers of North American Aviation company invented a C-shaped plate which could effectively dissipated the cannon gas, this solution was finally adopted for operational use on the late version of F-86H fighter with four M39 cannons.
Inspire by the success of the Gun Val program, USAF finally decided to accept the T-160 cannon as its next-generation air-combat weapon and renamed it as M39 20 mm cannon. The first operational fighter equip with M39 cannon was North American Aviation F-86H-5 Sabre fighter in mid 1950s, then it became the standard internal weapon on both North American Aviation F-100 Super Sabre fighter, McDonnell F-101A Voodoo long-range escort fighter and Northrop F-5 fighter.
