The Chengdu J-7 is the Chinese reverse-engineered counterpart to the Soviet MiG-21F-13, which first appeared in the mid 1960s. In upcoming update 1.91, pilots in War Thunder will have the chance to fly the later J-7II version - the crowning jewel of the brand new Chinese aviation tree also coming as part of the next update!
国营132厂(国营132厂于1998年改组为成都飞机工业集团有限责任公司)的歼-7II是中国通过苏联米格-21F-13逆向研发制造出来的,歼-7II于20世纪60年代中期投入服役。 在即将到来的1.91中,飞行员们将有机会驾驶歼-7II 。在1.91版本里,这架中国空军线上最耀眼的宝石将和整条中国空军科技树投入激烈的战斗中。

Historical Background 历史故事
In the early 1960s, the Sino-Soviet relationship was quickly deteriorating. In an effort to improve relations, the USSR invited top Chinese military officials to Moscow to oversee the production of the state-of-the-art MiG-21 interceptor and to negotiate possible licence-production. However, further deterioration of relations had a negative impact on the agreement, but in the end, technical documentation and components of the MiG-21 were eventually shared with China.
20世纪60年代初,中苏关系迅速恶化。为了改善关系,苏联邀请了中国高级军事官员到莫斯科监督最先进的米格-21的生产,并就可能的许可证生产进行相关谈判。然而,中苏关系进一步的恶化对协议产生了负面影响,但最终,米格-21的技术资料和部件最终共享给了中国。
However, Chinese engineers soon realized that the shared information and equipment was incomplete, thus making local production impossible at the time. As a result, a lengthy and painstaking reverse-engineering effort was launched. By the mid ‘60s, the first reverse-engineered J-7 was completed and undertook its maiden flight.
然而中国工程师很快便意识到苏联共享的生产资料和设备并不完整,这使得米格-21无法实现本土化生产。因此,中国工程师开始了漫长而艰苦的逆向工程。到了60年代中期,第一架通过逆向工程制造的歼-7原型机完成了她的首次试飞。
As series production just began, major unrests broke out in China following the start of the Cultural Revolution, which would go on well into the ‘70s. As a result, production of these early machines was met with great difficulties and only a few were built. In 1974, Chengdu Aircraft relaunched development of the project, continuing work on an improved design.
正当歼-7的量产逐渐步入正轨之时,十年浩劫席卷了中国大地,大混乱使得歼-7的生产被迫终止到70年代。当歼-7的生产试图恢复的时候,发现大多数生产资料已经损毁,这导致了这段时间歼-7生产的数量十分有限。1974年,国营132厂(成都飞机工业集团前身)重启了歼-7的研发过程,开始对其进行改进设计
This new version, designated J-7II, first took to the skies in late 1978 and featured several improvements, such as a Chinese-built ejection seat, a reworked canopy and a more powerful engine with increased service time and improved consumption, among other changes. Shortly after the maiden flight, mass production of the J-7II began and went on until 1986 with around 375 machines being built.
这个版本的歼-7被命名为歼-7II,于1978年末首次试飞并进行了多项改进,例如完全由中国制造的弹射座椅,再设计的风挡和更强大的发动机,增加了平均故障间隔时间,改善了燃油消耗以及其他的一些。在首飞后不久,J-7II开始批量生产并持续到1986年,大概有375架量产机被制造出来。
In War Thunder, the J-7II will be the top jet fighter available to pilots at rank VI of the new Chinese aviation tree, coming to the game as part of update 1.91. Compared to its Soviet counterpart - the MiG-21F-13, which is also coming to the game in update 1.91 - the J-7II shares much of its flight characteristics with the Soviet MiG-21, most notably differing in its firepower from the original.
在战争雷霆里,歼-7II将成为新的中国空军科技树6级载具,作为1.91版本的一部分加进游戏。 与同样在1.91中加入的苏联对手 米格-21F-13 相比,歼-7II与苏联米格-21的大部分性能相同,最明显的区别则是白板的火力不同。
The J-7II is equipped with a more powerful turbojet engine, which helps offset the increased weight of the J-7II in comparison to the MiG-21F-13. As a result, the J-7II retains neigh identical flight characteristics as the MiG-21F-13, being able to reach a top speed of 2,177 km/h (Mach 2,07) at an altitude of 13,000 m.
歼-7II配备了更强大的涡轮喷气式发动机,与MiG-21F-13相比更有助于抵消J-7II增加的重量。 因此,歼-7II保持了与MiG-21F-13相同的飞行特性,能在13,000米的高度达到2,177公里/小时(马赫数2,07)的最高速度。
As already mentioned, the standout feature which differentiates the J-7II from the MiG-21F-13 can be found within its firepower. The J-7II’s primary armament is doubled in comparison with its Soviet counterpart: instead of being fitted with only a single 30mm cannon with 60 rounds, the J-7II has access to two 30mm cannons and 120 rounds of ammunition in total. Though this might not seem like a substantial upgrade over the Soviet machine, it can still prove itself as highly useful during intense dogfights and may even play a decisive role in defeating your opponent. J-7II also has access to PL-2 air-to-air missiles, 2x16 rockets, as well as 2x500 kg bomb preset.
如前所述,歼-7II与米格-21F-13的不同之处在于它的火力配置。 与苏联的米格相比,歼-7II的火力增加了一倍:不同于只有60发炮弹,单门30毫米武器的米格-21,歼-7II配备了两门共120发子弹的30毫米机炮。 虽然目前并不能证明这项改动有什么实质性变化,但激烈的空战会证明这个改动是有效且值得的,它可能会在关键时刻起到决定胜负的作用。 歼-7II还可使用霹雳-2空对空导弹,两个各有16发火箭的火箭巢或者两枚500公斤炸弹。
The J-7II will appear in player hangars following the release of upcoming update 1.91 and will represent the top machine available to pilots in the brand new Chinese aviation tree, also coming to the game as part of the next major update. Until then, clear skies and happy hunting pilots!
