The F-1 is the first supersonic support fighter developed in Japan after the WWII, based on the advanced supersonic trainer T-2. And the T-2 is developed from JAGUAR in 1971. Mitsubishi is the primary contractor of both aircrafts. 日本F-1超音速支援战斗机是二战后日本发展的第一种战斗机，是在T-2超音速教练机的基础上改进而成的。T-2则是1971年在“美洲虎”的基础上改进来的。1965年前后，日本军方认为随着空中自卫队开始装备两倍音速的第二代超音速战斗机，例如F-104J和F-4EJ，必须研制一种超音速教练机（代号T-X），并在此基础上发展SF-X型单座战斗机。日本三菱公司是上述两种日本飞机的主承包商。 T-2 is used for training in JASDF(Japanese Air Self Defence Force), first flight in 20th Jul, 1971. T-2`s powerplant are two Ishikawajima-Harima TF40-IHI-801A augmented turbofan engines, based on Rolls Roys/Rolls-Royce/Turbomeca Adour Mk801 A. The thrust is 22.7KN and maxiume 32.5KN. Both pilots have ES-7J zero-zero eject seats.
T-2机头装有一台三菱电气J/AWG-11搜索测距雷达，三菱电气平视显示器(改进自汤姆森-CSF产品)，三菱电气J/ARC-51电台，日本电气公司J/ARN-53塔康系统，J/APX-101敌我识别装置，利顿5010BL导航系统。座舱配有空调系统。全机有两套独立的液压系统，压力为207×105帕(211千克/平方厘米)，用于飞行控制和收放起落架等。起落架应急放下用冷气瓶。电源系统为两台12/15千伏安交流发电机。 T-2的具体机体结构如下：该机采用悬臂式全金属上单翼，NACA65系(修形)翼型，相对厚度4.66%，根部下反角9°。翼根前缘后掠角68°，外翼段内侧部分的后掠角42°29′，外侧部分36°，1/4弦线后掠角35°47′。多梁式翼盒结构，梯形厚板机械加工翼梁，主要采用7075和7079铝合金。电气驱动的前缘襟翼大量采用铝蜂窝结构。铝蜂窝单缝式后缘襟翼占翼展的70%，同样由电气驱动。该机翼没有副翼。襟翼之前是液压操纵的全金属两段式开缝扰流器，主要负责侧向操纵。整体式液压作动的全动式后掠平尾采用悬臂式全金属结构，平尾下反角为15°，内侧前缘采用钛合金，外侧前缘采用铝合金，后缘为铝蜂窝夹层结构。后掠式垂尾的方向舵为液压操纵。后机身两侧下方各有一个小的腹鳍。 T-2采用普通全金属半硬壳式机身结构，以7075和7079铝合金材料为主，机身结构重量的10%为钛合金，主要位于发动机舱。后机身下部主轮舱的后方有两个液压驱动的门式减速板。为保证跨音速的加速性能和超音速性能，机身应用了面积律设计。机翼安装处呈蜂腰形。后机身下装跑道拦阻着陆钩。此外机上有减速伞。该机使用液压收放前三点式起落架。液压系统发生故障时，可用冷气系统操纵应急放起落架。主起落架采用超高压无内胎轮胎，规格为25×6.75-7型(18层)，最大轮胎压力为20.69×105 帕(21.2千克/平方厘米)，向前收入机身。前起落架可转向72°，也采用超高压无内胎轮胎，规格为18×5.5-7型(14层)，最大轮胎压力为14.82×105帕(15.1千克/平方厘米)，向后收入机身。前后均为单轮，有油气减震器、液压刹车和防滑装置。 The weapons of T-2 contain: one 20mm JM61 Vulcan six-barrel cannon with 750 rounds. There are five external hardpoints and two wing tip stations. T-2 can carry 2722 kg (6,000 lb) of disposable stores, including AAMs, ASMs, free-fall or guided bombs, rocket-launcher pods, drop tanks and ECM pods. T-2的武器包括，一门20mm JM61“火神”六管加特林炮，为美国M61的日本生产型，带弹750发。机上有5个外挂点和2个翼尖挂架。可携带多达2722千卡的外挂物，包括AIM-9空空导弹，以及AAM-1、AAM-2等日本产空空导弹，ASM-1和ASM-2反舰导弹，普通炸弹，火箭发射器，副油箱，电子对抗吊舱。
T-2总产量包括试验型号在内为96架，于1988年停产。5架T-2于空中自卫队“假想敌”中队服役，部分T-2是自卫队的“蓝色脉动”(Blue Impulse)飞行特技小组使用的座机。T-2实际上不仅是一种教练机，而且是一种有力的对地攻击机。缺点是执行作战任务时T-2的航空电子设备能力有限。目前T-2装备于日自卫队第四联队21和22中队。 The F-1 is a tactical support fighter version of the T-2. Facing the USSR fleets in Pacific, the F-1 is mainly design for carrying anti-ship missiles, such as AMS-1 & ASM-2, to destroy the USSR warships, as well as other combat missions. The original model's first flight was in 1975. Starting in 1976, a total of 77 units have been delivered and manufactured. The main difference between F-1 & T-2 is that F-1 only has one pilot. Now the F-1 fighters are deployed at Misawa Air Base. Since 1978, Mitsubishi had produced 77 F-1s for JASDF. F-1战术支援战斗机是T-2的改型。面对着苏联太平洋舰队的威胁，F-1主要设计用于使用日本ASM-1、ASM-2反舰导弹等摧毁苏联军舰，也可用于其他任务。F-1首飞于1975年，1976年起共生产部署了77架。F-1与T-2主要的区别是只有一名飞行员。目前F-1主要布置于MISAWA空军基地。1978年开始，三菱为日本空中自卫队生产约77架F-1。 The weapon system of F-1 is simliar to the T-2. The typical misson for F-1 is to carry two ASM-1 anti-ship missiles & one 830kg fuel tank, proceeding HI-LO-LO-HI anti-ship mission, radius 550km. If use LO-LO section, the radius is down to 370km. In all the missions, two AIM-9 missile are carried. F-1的武器系统与T-2类似。F-1典型的作战任务为携带2枚ASM-1反舰导弹及一个830千克副油箱时，以高-低-低-高剖面进行反舰任务，作战半径为550千米。如使用低-低剖面，半径减少为约370千米。所有任务中通常在翼尖挂架上挂2枚AIM-9“响尾蛇”导弹。
ASM-1反舰导弹
In Apr 1986, JASDF announced to increase the service life of F-1 from 3500hr to 4500hr, for 3 more service years. And a auto-piloting system would be added, as well as the AIM-9L missile. The windshield is modified to withstand the midium size bird strike in 926km/hr speed. 1986年4月，空中自卫队宣布将F-1服役寿命从3500小时延长至4500小时，相当于延长使用3年。加装1套自动驾驶仪，增加使用AIM-9L导弹的能力。改进挡风玻璃，能够在以926千米/时飞行时抵挡中等大小鸟类撞击。

T-2 has a Mitsubishi Eletonics J/AWG-11 search/range detection radar in the head, Mitsubishi Eletonics HUD based on Thomson-CSF design, Mitsubishi Eletonics J/ARC-51 radio, NEC J/ARN-53 TAKAN, J/APX-101 IFF & Lipton 5010BL navigation consultation system.
A total of 96 T-2 units, including the test models, have been manufactured until the end of production in 1988. Five of the T-2s is in the "TOP-GUN" units of JASDF, and some in the Blue Impulse Air Stunt Team. The T-2 is in fact not only a trainer, but also a powerful air-to-surface striker. The disadvantage of it is the avionics is limited for combat missions. Now T-2s are deployed in 4nd Wing / 21st Squadron ,Matsushima AB 4nd Wing / 22st Squadron ,Matsushima AB.
