Description
The Mitsubishi F-1 was the first supersonic fighter jet designed and built by Japan, as a joint project of Mitsubishi Heavy Industries and Fuji Heavy Industries. It derived from the Mitsubishi T-2 advanced jet trainer, which was influenced by the SEPECAT Jaguar. The F-1 had a specialized role in anti-ship and ground attack missions, with upgraded avionics, airframe and weapons capacity, including seven hardpoints and a built-in JM61A1 Vulcan. It replaced the F-86 Sabres in the JASDF's arsenal.
It was introduced in Update "New Power". The F-1 is a versatile fighter that can perform different roles depending on the mission. It can attack both air and ground targets with its 20 mm JM61A1 cannon, with 750 rounds of ammo and can damage light armour and aircraft. It can also carry up to ~2,500 kg of ordnance on seven hardpoints, such as AIM-9P Sidewinder missiles, bombs and rocket pods. The on-board ballistics computer can help guide the ordnance (including the cannon) to ground targets. The F-1 does not have any countermeasures like flares and chaff, so it needs to be careful when facing enemy missiles. A possible workaround is to use the FFAR rocket pods as makeshift flare pods and fire a volley or so to break missile locks.
General info
Flight performance
The sleekness of the aircraft lends itself to flying fast and speed should be maintained when flying, especially during air-to-air combat as a slow-flying F-1 is a relatively easy target due to poor manoeuvrability at slow speeds. To help in instances where the aircraft must fly at slower speeds (landing, bombing and ground rocket attack), slats and spoilers help create a higher lift capacity and roll rate, preventing the aircraft from stalling and plummeting.
Air-to-air combat should be avoided when carrying bomb loads, as this will significantly decrease manoeuvrability. During a ground attack, all efforts should be made to get to the target as soon as possible and release the heavy ordnance and then proceed to any aerial combat in the near vicinity.
Damage to the aircraft, especially to the wings, will typically result in the destruction of the aircraft. Due to their relatively small size, any loss in surface area will cause the fighter to over-lift on the good side, sending the aircraft into a roll and then potentially into a flat spin.

Survivability and armour
The F-1 fighter, like many of the newer aircraft, has shed most of its armour in return for better speed and agility. The only armour outfitted on the previous T-2, the 38 mm bulletproof glass situated between the fore and aft cockpit, is NOT present, having been removed with the aft cockpit. Pilot sniping is therefore increased in likelihood in comparison with the T-2.
Damage sustained to the wings will not affect fuel loss as no tanks are mounted here; they are only mounted within the aircraft's fuselage. While many aircraft can absorb a huge amount of ammunition rounds in the fuselage before losing something important when it comes to the F-1 fuselage hits typically result in a hit to the engines, oil coolers, fuel, pilots or the radar. This is where pilot skill and manoeuvring come into play to make it very difficult for an enemy pilot to get a firing solution. High-G manoeuvres within this aircraft may hurt the speed and manoeuvrability; however, it may save the pilot's lives by causing many missiles such as the AIM Sidewinders to miss due to their lower g-turn threshold.

Offensive armament
The F-1 is armed with:
- 1 x 20 mm JM61A1 cannon, chin-mounted (750 rpg)
The JM61A1 20 mm Vulcan cannon is a monster and at the same time a headache for new pilots not used to it. Unlike most other machine guns and cannons in the game (or in real life for that matter), trigger depression here does not immediately produce flying bullets. Due to the characteristics of the JM61A1 cannon, it requires an initial spool-up time or spin of the cannon barrels before ammunition can be fired. The high rate of fire can easily melt the barrel, however with the rotating barrels, each barrel can cool off enough before it is its turn again to prevent damage. To initiate this, trigger depression will result in a .25 second delay before the ammunition begins to fire to allow the barrels to get to proper rotating speed. Once it gets going, 750 rounds of ammunition do not last very long.
When targeting an aircraft, for example, the pilot must remember this formula to be successful while leading an aircraft or before an aircraft passes through the crosshairs, start squeezing the trigger about .5 to .25 seconds before that event, and the cannon rounds should land on target. Waiting until a target passes through the crosshairs (unless tailing them) will result in a miss as they will be out of the sights before the cannon starts firing.
Trigger discipline is necessary when using this cannon as due to its rate of fire (about 6,000 RPM, ~100 RPS or 5 seconds of ammunition) will easily blow through the 750 rounds carried by the F-1.

Usage in battles
- Air-to-Air
The F-1 is a challenging aircraft to fly at its high BR, as it has mediocre flight performance and only rear-aspect missiles. The F-1 should adopt a passive playstyle and rely on the team's support. The AIM-9Ps can be very effective if the enemy is unaware of or distracted by the F-1's presence. However, if the enemy is alert and dodging, the F-1 will have a hard time finding a good launch angle, even with the radar-slaving feature. Moreover, many aircraft have flares that can decoy the missiles. Therefore, surprise is essential for the F-1's success. The F-1's cannon can also be very effective with accurate or lucky shots, but dogfighting is not recommended for this aircraft due to its inferior performance. The F-1 consumes a lot of fuel, so 30 minutes of fuel is at minimum recommended for most matches. Like the T-2, the F-1's wings will break off in high-speed negative G manoeuvres. Another drawback of the F-1 is that it lacks any countermeasures such as flares or chaff, which can be compensated by loading FFAR missiles and using them as makeshift flares, but this will increase the drag for the plane in exchange for more survivability against missiles.
A strategy player can adapt to, particularly in downtiers, is to climb to high altitude (6500-8500m) and waiting for furballs to take place. While other aircraft are engaging one another, use the AIM-9Ps to destroy enemy aircraft in low energy/altitude states, then zoom back up to altitudes.
Using keyboard input to assist manoeuvres can be very helpful, as the aircraft tends to wobble around its central axis with mouse aim only.
- Air-to-Ground
With the ballistics computer, the F-1 can prove exceptional in the role of close air support with its bombs, rockets and even gun, if complete air superiority has been accomplished. Though, with the lack of countermeasures, pilots will find themselves vulnerable to SAMs if not addressed properly. Its exceptional radar system often provides an advantage over enemy air combatants. Flying low, once an enemy aircraft has been located, it's often a good idea to turn off the search or lock radar as the chance is often great that the enemy is equipped with a RWR, alerting them to your presence and your upcoming attack. Again though, the F-1 suffers greatly when forced into drawn out engagements with the more capable enemies at its battle rating, though the opposing aircraft in this mode are not always similar in battle rating.
Pros and cons
Pros:
- Ballistics computer simplifies unguided weapon usage
- Powerful JM61A1 rotary cannon

Cons:
- Burns through fuel at an astronomical rate
- The JM61A1 rotary cannon doesn't shoot instantly; has a short spool up time which may take getting used to
- Poor energy retention
- Extremely poor low-speed manoeuvrability (under 500 km/h)
- Requires good trigger discipline and aim as the gun burns through ammunition
- Larger turning radius compared to most other jet fighters it can face
- Below average acceleration
- No countermeasures
- Generally outclassed in flight performance by other aircraft at or even below its battle rating
- Frequently uptiered into areas where all aspect missiles are common
History
The Mitsubishi F-1 was an indigenously-produced Japanese supersonic fighter aircraft that served with the Japanese Air Self Defence Force (JASDF). Based on the earlier Mitsubishi T-2, the aircraft first flew in 1975 and entered service a short time later.[1] A total of 160 aircraft were initially ordered, but the order was reduced to 77 airframes due to budget constraints.[1] In service, the aircraft served as an anti-shipping platform and was intended to fire the Mitsubishi ASM-1 anti-ship missile at enemy naval vessels.[2]
By the time it entered service, the F-1 had already grown obsolete due to it being relatively underpowered and unsuitable for air combat manoeuvring. Despite this, F-1s of the JASDF served until 2006, being replaced by modernized variants of the F-4EJ and the Mitsubishi F-2.[1][2]
Design and development
The Mitsubishi F-1 was developed from the T-2, a jet trainer and the first Japanese-designed and manufactured aircraft to break the sound barrier.[1][2] The F-1 was almost identical to its trainer counterpart; the main visual difference was that the F-1's rear cockpit was faired over to make room for an avionics bay. The aircraft featured a J/AWG-12 radar, an upgrade over the T-2's J/AWG-11 and similar to the Phantom FGR.2's AN/AWG-12 radar. The aircraft also gained a centreline hardpoint for an external drop tank, allowing the aircraft to use all of its wing hardpoints to carry munitions.[1][2]
Due to the design requirement specifications, the F-1 was otherwise highly similar to the T-2, retaining its engines, airframe and armament. It was so similar that the first pair of F-1s were developed from T-2 airframes taken off the assembly line.[1] The first prototype F-1 flew on June 3rd 1975, while the first production aircraft flew in mid-1977.[1] The aircraft was accepted for production and service with the JASDF.[1][2]
Operational history
The first order for twelve F-1 aircraft was approved in the 1975 fiscal year, and the first aircraft deliveries began in 1978. The F-1 entered full operational service and was initially used by the 3rd Squadron of the 3rd air wing at Misawa Air Base.[2] The aircraft eventually equipped a total of three squadrons, being the 3rd and 8th Squadrons at Misawa and the 6th Squadron at Tsuiki Air Force base. Deliveries of the F-1 were completed in 1987, with only 77 aircraft being delivered; this was due to the budget constraints of the JASDF.
In service, the F-1 was intended to be used as a low-altitude anti-ship attack aircraft, utilizing the Mitsubishi ASM-1 air-to-ship missile.[2] A reconnaissance variant of the F-1 was also planned but was cancelled in favour of the RF-4EJ Phantom.[1] Due to the design of its airframe and lack of engine power, the F-1 was rather unsuited for the air-to-air role and soon became obsolete. Despite this, the JASDF program to deliver a replacement stalled,[2] and the F-1 soldiered on until the early 2000s. During this time, the F-1s were given a service life extension (SLEP) upgrade, which increased their service life from 3,500 to 4,000 hours.[1] In the early 2000s, the F-1s were gradually retired, replaced by the F-4EJ and F-15J in the conversion training role and by the T-4 in the standard training role.[1] In its combat role, aircraft was replaced by the Mitsubishi F-2, a derivative of the American F-16 Fighting Falcon.[2] The last F-1s served on until 2006; it never saw combat nor fired shots in anger.[1]
