The j-20 no match for F22， and India not us-Japan

"Global military reported that" according to Canada of the Han and defense review reported on April 25, within the next 20 years, Japan and the United States, and Korea are deployed F-35A/B/C fighter, b-type equipment United States Marine Corps, maritime self-defense force could be potential uses, c-major deployment of an aircraft carrier. From Japan to build 22DDH and US forces prepared to introduce 45000 tons dock landing ship judge, once the 2 22DDH and 2 wooden dock landing ship in place before and after preparing 2020-2025, the maritime self defense force capable of deployment of 8x4 or 12x4 F-35B at least 48 F-35B, showdown will be equipped with 2, 3, "Liaoning" class aircraft carrier 48, 72 f-15 aircraft. As for the air self-defense force, has decided to introduce 42 F-35A,2016 years day hoping to get at least 4 F-35A aircraft for combat evaluation, therefore, F-35 time to empty, it is possible to service earlier than the j-20.

East Asian skies without a doubt entered the era of F-22, F-35, j -20, the latter is used? Each country developed fighter aircraft, surface ships, must be for specific operational environments and top imaginary enemies, even selected the same models, ship types, different countries, different combat environments, has a different meaning. For example, is an outdated slide, jump and landing an aircraft carrier, India and China have been carried out, but different, India's first fight is Pakistan, wartime embargo imposed by Pakistan's main naval base, on the India ocean surface warship air strikes in Pakistan, based on the concept of warfare, even if it is an outdated slide, jump and landing an aircraft carrier, still lacks it.

China managed to offend major combat targeting US military, the Japanese military, which raises different weapons design issues, in India, in China alone, may not be used. This is why the cold war years, every Soviet-designed weapons, are counting on to catch up with the US military, the same class because of the weapons showdown with us troops. Development plan is typical of the T10, focused exclusively on F-15, making change, early T10 impossible in terms of mobility over the F-15, Soviet believed that such investment is wasted, redesigned, if only for the Chinese, the original design is enough.

In accordance with the j-20 is currently such a design layout, where mobility, stealth, radar, weapons and equipment is no match for the F-22, it is out of question. Would now like to discuss the fighter -20 with F-35A/B/C of the case, may suffer.

First is F-35A,2016 years later, first air self-defense force, followed by the US military bases in Japan, are likely to continue to dress up an empty F-35A.

From pneumatic profile Shang, F-35A follow-up has is good of stealth performance, but must description, F-35A is not fifth generation full-time empty u fighter, real of name is joint attack fighter, attack of performance row in fighting zhiqian, it while also will replaced A10 attack aircraft, this is F-35 not pursuit supersonic cruise of causes, even so, due to using has over 35% of carbon fiber composites, and big thrust of F135 Engine, F-35A of overload still design for 9G, Standards achieved air superiority fighter, weapons load of up to 8 tons, empty weight of only 13 tons of F-35A, normal takeoff weight of 22.4 tons, almost same as Su27! so loaded with ammunition cases, F-35 thrust-weight ratio is not high, A/B/C-0.81, 0.85 0.71, respectively. Carrying case of air-to-air missile, F-35A thrust-weight ratio still could be close to 1, with the vector engine, air combat mobility cannot be underestimated.

Key is a stealth design, extensive use of composite materials, has reason to believe that F-35A of stealth performance is better than the j-20, j-31. F-35A using a diamond-shaped wings, all surfaces can hardly see the sharp angle, tilt of twin-vertical tail, large strake wing integration achieved with stealth. The horizontal tail is made of moving from Shenyang Jian -31 testing machine main wing design diamond shape can be seen, j-31-great reference designs for F-35. Both fighters are using DSI inlet, greatly reduces the weight. Don't see third-generation fighters with their own boundary layer separation. Also uses a diamond-shaped design, smaller dimensions than the j-20, on the one hand contribute to the invisible, while reducing weight.

Careful attention to the F-35, the j-20 aircraft, F-22 surface treatment can be seen, quite subtle American Stealth fighters, you don't see too many antennae, most antennas arranged in a half-buried, take a look at the j-20, you can still see several antennas.

F-35A power is the most powerful fighter, F135-PW-100, military thrust to reach maximum thrust up to 18000 kg 125kN, thrust-weight ratio up to 11.46, compression ratio is 28.

F-35B greater emphasis on attack, mobility is lower than F-35A, F-35A/C maximum speed for only M1.6-M1.7,B, thanks to lifting with short take off and landing capabilities, aircraft under its own weight increased, but with VTOL capability. Empty weight increased to 14.5 tons, must reduce the fuel savings, reduced from a 8.39 tons of fuel to 6.03, combat radius and therefore to fall from a-1090 miles 833 kilometers.

　　【环球军事报道】据加拿大《汉和防务评论》4月25日报道，未来20年内，日本、美国、韩国都将部署F-35A/B/C型战斗机，B型装备美国海军陆战队，海上自卫队也会是潜在使用国，C型主要部署航母。从目前日本建造的22DDH和准备引进45000吨级的美军船坞登陆舰判断，一旦2艘22DDH和2艘船坞登陆舰在2020-2025年前后准备到位，海上自卫队有能力部署8x4或者12x4架F-35B，至少48架F-35B，对决届时装备2、3艘“辽宁”级航空母舰的48、72架歼-15。至于航空自卫队，已经决定引进42架F-35A，2016年日希望获得至少4架F-35A用于作战评估，因此，F-35进入空自的时间，有可能比歼-20服役更早。

　　东亚的天空毫无疑问进入了F-22、F-35对歼-20的时代，后者是否中用？每一个国家研制战斗机、水面舰，必须针对具体的作战环境和首要假想敌，即使是选择同一机种、舰种，不同的国家、不同的作战环境，意义都不同。例如同样是过时的滑跳起降式航母，印度、中国都运用，但是意义不同，印度的首要作战对象是巴基斯坦，战时封锁巴基斯坦主要的海军基地，对出入印度洋的巴基斯坦水面舰实施空袭，基于这样的作战构想，即使是过时的滑跳起降式航母，依然够用。

　　中国得罪的主要作战对象是美军、日军，这就引发了不同的武器设计问题，在印度够用，在中国就有可能不中用。这是为何冷战年代，苏联设计的每一种武器，都指望必须赶超美军，能够与美军的同一类武器对决的原因。T10的开发计划就是典型，完全针对F-15，因此进行了大改，早期的T10不可能在机动性方面超越F-15，苏军认为这样的投资是浪费，因此重新设计，如果只是针对中国，原来的设计方案足够用。

　　依照歼-20目前这样的设计布局，在机动性、隐形性、雷达性能、武器装备方面都不是F-22的对手，这一点是无疑的。现在要讨论的是歼-20在碰到F-35A/B/C的情况下，可能的遭遇。

　　首先是F-35A，2016年以后，首先是航空自卫队，其次是美军驻日基地，都有可能陆续换装空优型的F-35A。

　　从气动外形上，F-35A贯彻了很好的隐形性能，但是必须说明，F-35A并非第五代专职空优战斗机，真正的名字是联合攻击战斗机，攻击的性能排在战斗之前，它同时也将取代A10攻击机，这是F-35不追求超音速巡航的原因，即使如此，由于使用了超过35%的碳纤维复合材料、大推力的F135发动机，F-35A的过载依然设计为9G，达到了空优战斗机的标准，武器载重量高达8吨，空重仅有13吨的F-35A，正常起飞重量达到22.4吨，几乎与Su27相同!因此在满载弹药的情况下，F-35的推重比不高，A/B/C型分别为0.81、0.85、0.71。在只携带空空导弹的情况下，F-35A的推重比依然可能接近1，配合矢量化的发动机，空战的机动性依然不能低估。

　　关键的是隐形化的设计，大量复合材料的运用，有理由相信F-35A的隐形性能要好过歼-20、歼-31。F-35A采用了菱形的机翼，所有的翼面几乎看不到锐角，倾斜式双垂尾、大边条与机翼融合等方式实现了隐形。水平尾翼是全动式的，从沈阳歼-31试验机的菱形主翼设计外形可以看出，歼-31极大参考了F-35的设计。两种战斗机都采用DSI进气道，大大减轻了重量。看不到第三代战斗机惯用的境界层分离板。机首也采用了菱形设计，尺寸比歼-20小，一方面有助于隐形，同时降低重量。

　　仔细注意F-35、歼-20、F-22的飞机表面处理可以看出，美式隐形战斗机的处理相当细微，看不到过多的天线，多数天线都以半埋方式排列，再看看歼-20，依然可以看到若干天线。

　　F-35A的动力是战斗机中最为强悍的，F135-PW-100的最大推力高达18000公斤、军用推力也达到125kN，推重比高达11.46，压缩比为28。

　　F-35B就更加强调对地攻击，机动性比F-35A低，最大速度F-35A/C为M1.7，B型只有M1.6，由于采用了具备短距起降能力的升力器，飞机自身的重量加重，但是具备了垂直起降能力。空重就此增加到14.5吨，必须减小机内燃料储蓄，从A型的8.39吨机内燃油降低到6.03吨，作战半径因此从A型的1090公里下降到833公里。
