歼-7D(J-7IIIA)于1990年8月20日由中国空军成功试飞，1995年12月25日定型，并更名为歼-7D
根据罗马尼亚，埃及提供的米格21MF以及相关资料，数据仿制而来的非传统的歼7。
歼7D与1995年12月25日通过审批后正式进入批量生产，随后于1998年停产，产量很少。
he J-7D (J-7IIIA) successfully conducted its maiden flight by the Chinese Air Force on August 20, 1990, and was finalized and renamed as the J-7D on December 25, 1995.
It is an unconventional J-7 reverse-engineered based on the MiG-21MF provided by Romania and Egypt, along with related data.
fter approval on December 25, 1995, the J-7D entered mass production and was subsequently discontinued in 1998 with a limited production run.
If you are interested in the J-7D aircraft, feel free to leave a comment below, and I will actively respond.
对比与歼7C(J-7III)，它的主要改进方案一一下几点：
Compared to the J-7C (J-7III), its main improvements are as follows:
- 换装涡喷13FI发动机，增加推力
Replacement with the WP13FI turbojet engine to increase thrust. - 由KH-03D瞄准具替换为平面显示器
Replacement of the KH-03D gunsight with a flat-panel display. - 安装大气数据计算机
Installation of an air data computer. - 采用265雷达高度表，930-4型全向雷达告警系统，941-4A箔条/红外干扰弹投放器
Adoption of the 265 radar altimeter, 930-4 omnidirectional radar warning system, and 941-4A chaff/flare dispenser. - 仪表系统角速度信号器小型化
Miniaturization of the angular velocity indicator in the instrument system. - 采用空速一马赫数组合指示器
Use of an airspeed-Mach number combined indicator. - 可挂载霹雳-7，霹雳-8等新型空空导弹
Capability to carry new air-to-air missiles such as the PL-7 and PL-8.
现在游戏中歼7D使用的RWR是错误的！它就是换皮的SPO-10，就米格21MF那个RWR，连座舱都是套皮米格21MF，就装了个平面显示器，还特么是歪的，这些错误都需要更正！
歼7D使用的RWR和歼7E是一模一样的，930-4是自用名称，KJ8602是外贸名称，所以歼轰7A的KJ8602A这个名字也是错的
The RWR used by the J-7D in the game is incorrect; it is actually the MiG-21MF’s SPO-10RWR. Even the cockpit directly uses the MiG-21MF’s design, only with the addition of a flat-panel display that is not centered. All these errors need to be corrected! The RWR used by the J-7D is exactly the same as that used by the J-7E. The 930-4 is the name used by the Chinese military, while the KJ8602 is the export name. Therefore, the KJ8602A used by the JH-7A should also be changed to 930-4A.
当然，史实是能挂霹雳8的，但是大家应该都明白，给了霹雳8这飞机就废了，所以在这里我注重于争取全向RWR和250-2燃烧弹还有IFF敌我识别，以及修正错误的飞机座舱！
Historically, the J-7D/E could be equipped with the PL-8 all-aspect dogfight missile. However, it’s understood that if the J-7 in the game could be equipped with the PL-8, it would certainly increase its BR (Battle Rating), which would be a nightmare for this aircraft as you wouldn’t be able to enjoy piloting it at a higher BR. Therefore, I focus on advocating for the digital omnidirectional radar warning system and the 250-1 incendiary bomb, as well as IFF (Identification Friend or Foe) and correcting the erroneous aircraft cockpit.
歼7D 930-4型RWR具有全向雷达告警功能issue
The J-7D’s RWR has a 360° radar warning capability // Gaijin.net // Issues
其实有一点很难绷的地方大家可能都没发现，那就是：gaijin在建模的时候就已经给歼7D加了930-4型全向雷达告警接收器的天线模型，却没有给全向雷达告警，幽默
Actually, there’s a funny thing that many people might not have noticed: Gaijin, during modeling, already added the antenna model of the 930-4 omnidirectional RWR to the J-7D, but didn’t provide the omnidirectional radar warning system. It’s quite amusing.
没错，这个像揽子一样的东西就是
That’s right, this thing that looks like a pair of testicles.
