Description
The J-7D (Chinese: 歼-7D, previously J-7IIIA; unified NATO codename: Fishcan) is a premium gift rank VII Chinese jet fighter with a battle rating of 10.7 (AB), 11.0 (RB), and 11.3 (SB). It was introduced in Update "Apex Predators".
The reverse-engineered version of the MiG-21MF from Egypt for all-weather operations, J-7D offers very similar performance to the late MiG-21 series with better engine and higher fuel capacity. While it lacks SARH missiles for head-on/interception missions and large-calibre rockets like S-24s, the overall combat capabilities can be still ensured by its IR AAMs and variety of Chinese ground-attack weaponries.
General info
Flight performance
Taking a look at J-7D, other than its default grey-tone camo and the PLAAF roundel onboard, the jet itself looks extremely similar to the late MiG-21 series with R-13F-300 engines. This is indeed true as J-7III series (C and D) were both based on MiG-21MFs exchanged from Egypt; in short, J-7D flies very similarly to the MiG-21MF in LSK (East German) service. The later variants of the Fishbed feature higher fuel capacity (the "spine" is filled with fuel tanks) and higher engine thrust, as well as featuring a new RP-22 radar; the J-7D exhibits all of the aforementioned upgrades. The lighter weight and higher thrust of the WP-13F1 engine also ensures a faster speed even against a MiG-21bis while having slightly better manoeuvrability as well; do remember that the J-7D is still an interceptor after all, so in most cases utilising its speed is more than enough to take out enemies at its tier. But do beware of light fighters or tailless delta-wing jets in one-on-one dogfights, it's better to quit the fight and wait for better chance to take them down in one pass.

Survivability and armour
Other than the airframe and aluminium alloy skin, the J-7D has no additional protection; any hits from enemy weapons are very likely to either severely damage the jet or take out the pilot straight away. However, an EFS system and self-sealing tanks are present onboard, giving it some chance to return to the airfield if it survives subsequent assaults from enemies.

Armaments
Offensive armament
The J-7D is armed with:
- A choice between two presets:
- 1 x 23 mm Type 23-3 cannon, belly-mounted (200 rpg)
- 1 x 23 mm Type 23-3 cannon + 72 x countermeasures
Suspended armament
Describe the aircraft's suspended armament: additional cannons under the wings, bombs, rockets and torpedoes. This section is especially important for bombers and attackers. If there is no suspended weaponry remove this subsection.
Usage in battles
Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
Pros and cons
Pros:
- Better engine thrust than most previous J-7/MiG-21 series thanks to the WP-13F1 engine
- Access to search radar
- Relatively better light rocket options than Soviet MiG-21MF/S series
- Devastating PL-5B or PL-7 missiles at its disposal
- Built-in countermeasures with 72 salvos, unlike its Soviet cousins
- Has full ballistic computer for cannon, rockets, and bombs; useful in ground attack
Cons:
- Bleeds energy severely during manoeuvres due to delta wing design
- Heavier than J-7E
- Poor radar performance with shorter range than common foes like F-14, F-4E
- Lacks all-aspect IR missiles and SARH missiles
- Below average pylon counts for its tier
History
By the time the Type 62 and subsequent J-7I/II series went into commission with the PLAAF in the late 1960s, the PLAAF was already seeking a new fighter for all-weather interception and to replace earlier jets in service. Although the J-8 program was also started around the same time, it was only until 1979 when J-7II was finalized and J-8I was passed for certification. This also called for a back-up for the J-8I series. During the late 1970s economy reform and increasing international arms trade with foreign countries, Chinese engineers visited countries with MiG-21MFs in service and took the design for future use; CATIC also exchanged some Soviet equipment from Egypt including MiG-23SM and MiG-21MF as the reverse-engineer subject for new interceptors.
The new J-7III started its development in March 1979 by CAC and after 5 years of repairing MiG-21MFs while building domestic prototypes, the J-7III took its first flight on 26th April 1984 and subsequent flight tests continued until 1988 when the first batches rolled off the production line. The reverse-engineered jet featured a new engine and a domestic JL-7 radar based from Type 317A radar from the failed Q-5 Yi (强-5乙, perhaps the very last torpedo bomber ever developed), but engine production issues hindered the further production of J-7III (now called J-7C under new designation) with only 17 of them built. Meanwhile, as the J-7III continued to be developed, CAC and GAIC worked on new electronics and countermeasure systems as well as a new WP-13F1 engine for the new jet. The new jet, developed in 1988, featured a new JL-7A radar capable of launching the latest PL-8 missiles, reverse-engineered Marconi Type 956 HUD, as well as Type 930-4 countermeasure system. J-7IIIA (now called J-7D) took its first flight in mid-1991 and joined the PLAAF in 1995.
Due to changes in combat doctrine, introduction of more advanced Su-27SK Flanker-B and J-7E, as well as J-8II series becoming combat-capable in 1990s and the successful development of Project No. 10 (J-10), the J-7D was deemed unnecessary and only 39 of them were built by 1999 as the placeholder for new jets; these jets made it into their first and only appearance in the National Day Parade of 1999, alongside with Flankers and air-refuel-capable J-8D.
