In RB, speed is life on this plane. First thing that should be done after takeoff is gaining at least 800-900 kph IAS in level flight and zoom climbing to around 2 km(or we can fight even at the deck, all depends on situation). Maintaining speed at 800 kph is very important. BnZ is main tactic, don't engage in vertical with MiG-15bis. Sabre easily outdive MiG-15bis(Sabre have higher top speed, which means MiG-15bis won't be able to catch Sabre in level flight/dive). Avoid flying slow and turnfighting.

The F-86F-2 was the designation given to 10 aircraft (4 F-86E and 6 F-86F) modified to carry the M39 Revolver cannon in October 1952. They were fitted with larger and strengthened gun bays to make them able to receive the new cannons. They were tested at Edwards AFB and the Air Proving Ground at Eglin AFB. Eight of these aircraft were then shipped to Japan (two were lost during testing due to the compressors ingesting excessive propellant gases from the cannons). Seven of these aircraft were then deployed to Kimpo Airfield as "Project GunVal" for a 16-week combat field trial in early 1953.
+
=== 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.
  
−
The F-86F-2 is the official designation for F-86E and F aircraft that were retrofitted with strengthened and enlarged gun bays to carry the new T-160 cannon developed from the captured Mauser MG 213, a German autocannon which never saw service. The aircraft were flight tested at Edwards and Eglin Air Force Bases. The aircraft were then relocated to Kimpo Airfield for tests in actual combat. Two aircraft were lost after the engine ingested excessive amounts of exhaust gases from the cannons.
+
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).
  
−
The F-86 is considered one of the best fighter jets of the Korean War. It is the most-produced Western fighter, with almost 10,000 aircraft produced by the US, Australia, Canada (as the re-engined CL-13), Italy, and Japan.
+
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.
  
−
The F-86 was developed by North American Aviation, the creator of the venerable P-51 Mustang. The XP-86 prototype was created to meet the USAF requirement for a high-altitude escort fighter. It was derived from the Navy's FJ-1 Fury, a transitional fighter jet that borrowed the wings, tail surfaces and canopy from the P-51D. The XP-86 was under threat of cancellation because the XP-80 and XP-84 had similar performance characteristics and were farther ahead in development. However, North American designers made a radical change to the design and replaced the straight wing with a swept wing, which was shown by seized German research to greatly reduce drag and increase performance at high speed. The resulting performance boost was so significant that the swept-wing prototype of the XP-86 was supposedly able break the sound barrier in a dive a few days before Chuck Yeager made his official attempt.
+
[[File:F-86F-3 with Oerlikon cannon.jpg|left|thumb|353x353px|F-86F-3 armed with Oerlikon cannons.]]
 +
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 F-86F-2 is the designation for four F-86E and six F-86F aircraft that were retrofitted to carry four 20mm T-160 (later designated M39) revolver cannons. The cannon was derived from the Mauser MG 213, a prototype aircraft cannon developed by the Germans at the end of World War II, which also served as a basis for the British ADEN and French DEFA cannons. The aircraft were deployed to Kimpo Airfield for trials in combat in 1953. Despite losing two aircraft after compressor stalls from ingesting too many exhaust gases from the new cannons, the M-39 cannon became the standard armament for the F-86H, a fighter-bomber variant with a more powerful engine.
+
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.
 +
[[File:See-through of F-86H and its M39 cannons.jpg|thumb|342x342px|F-86H with M39 cannons, the successor of T-160 and the Gun Val project.]]
 +
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.

Usage in battles

In RB, speed is life on this plane. First thing that should be done after takeoff is gaining at least 800-900 km/h IAS in level flight and zoom climbing to around 2 km (or we can fight even at the deck, all depends on situation). Maintaining speed at 800 km/h is very important. BnZ is main tactic, don't engage in vertical with MiG-15bis. Sabre easily outdive MiG-15bis (Sabre have higher top speed, which means MiG-15bis won't be able to catch Sabre in level flight/dive). Avoid flying slow and turnfighting.

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.

  • Air-brake is less effective than some opponents'

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.

F-86F-3 armed with Oerlikon cannons.

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.

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.

F-86H with M39 cannons, the successor of T-160 and the Gun Val project.

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.
