Description
The J-7E(Chinese: 歼-7E) is a rank VII Chinese jet fighter with a battle rating of 10.7 (AB) and 11.0 (RB/SB). It was introduced in Update "Red Skies".
Based on the already well-developed J-7II and their modifications (J-7IIH/B/M; C/D), J-7E offers a very different way to upgrade a Fishbed- not only it has a more powerful engine and additional fuel, it also comes with the iconic Chinese Fishbed's double-delta wing with slats, making it a formidable competitor in terms of overall maneuverability and especially at lower speeds, which none Soviet Fishbeds can ever offer. With its newer PL-5B missile comes into commission, J-7E can prove its abilities over his competitors and use its amazing maneuverability to finish off enemies once and for all.

Survivability and armour
Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.

Armaments
Offensive armament
The J-7E is armed with:
- 1 x 30 mm Type 30-1 cannon, belly-mounted (60 rpg)
Because the addition of a new fuel tank to the lower left side of the aircraft and compensate for the weight of newer missiles, unlike his predecessor, J-7E has only a single Type 30-1 cannon on the starboard. For pilots without good skills, these 60 rounds will be very painful to use albeit 30mm gun has good ballistic and damage (a few round burst can tear down most aircrafts) ; while in SB, J-7E comes with a HUD and the rangefinder is linked to it, making it somewhat useful to track down enemies and gun them down with a bit more precision.
Suspended armament
The J-7E can be outfitted with the following ordnance:
- Without load
- 2 x PL-2 missiles
- 2 x 250 kg 250-3 bombs (500 kg total)
- 2 x PL-2 missiles + 2 x 250 kg 250-3 bombs (500 kg total)
- 2 x PL-5B missiles + 2 x 250 kg 250-3 bombs (500 kg total)
- 4 x 250 kg 250-3 bombs (1,000 kg total)
- 2 x 500 kg 500-3 bombs (1,000 kg total)
- 2 x 500 kg 500-3 bombs + 2 x 250 kg 250-3 bombs (1,500 kg total)
- 2 x PL-5B missiles + 2 x 500 kg 500-3 bombs (1,000 kg total)
- 2 x PL-2 missiles + 2 x 500 kg 500-3 bombs (1,000 kg total)
- 4 x PL-2 missiles
- 4 x PL-5B missiles
- 2 x PL-5B missiles
- 2 x PL-2 missiles + 2 x PL-5B missiles
- 8 x Type 130-2 rockets
- 2 x PL-2 missiles + 8 x Type 130-2 rockets
- 2 x PL-5B missiles + 8 x Type 130-2 rockets
- 16 x Type 130-2 rockets
- 14 x Type 90-1 rockets + 8 x Type 130-2 rockets
- 8 x Type 130-2 rockets + 2 x 250 kg 250-3 bombs (500 kg total)
- 8 x Type 130-2 rockets + 2 x 500 kg 500-3 bombs (1,000 kg total)
- 14 x Type 90-1 rockets + 2 x 250 kg 250-3 bombs (500 kg total)
- 14 x Type 90-1 rockets + 2 x 500 kg 500-3 bombs (1,000 kg total)

- 2 x PL-2 missiles + 14 x Type 90-1 rockets
- 2 x PL-5B missiles + 14 x Type 90-1 rockets
- 28 x Type 90-1 rockets
Usage in battles
Since J-7E is still based on the MiG-21 family, their playstyle are very similar in the game.
(To be edited)
Pros and cons
Pros:
- New engines with higher thrust and overall acceleration thanks to the lighter weight than Soviet Fishbeds.
- Unique double-delta wings that gives impressive maneuverability at its tier.
- The very first Chinese aircraft with a multifunctional HUD, and the first PLAAF aircraft that came with CCIP.
- Comes with RWR and 72 countermeasures
- PL-5B missiles, if used properly, can make very short work of your enemies with its 30G overload.
- Vast variety of ground attack weaponries.
Cons:
- Came with single gun on starboard and with 60 rounds.
- Missile launch overload at only 4G
- Doesn't come with any semi-active missiles due to the lack of radar
History
The story of J-7E goes way back to 1980s.
During the early 1980s, Mainland China has better relationships with European countries which seek for opening up their military equipment market; thus during these days the older J-7II received a overhaul upgrade coded J-7B (or F-7M in foreign market) with British electronic equipment; while at the same time Chinese got their hands on a few MiG-21MF from Egypt for upgrading the PLAAF fleet with a faster and radar-equipped aircraft, which later became the J-7C/D but they failed to meet Central Military Commission's and PLAAF's requirements on low speed dogfights, but they did impressed by the R-13-300 engines on them and thus it became the Shenyang Liming WP-13 engine.

So the CAC (Chengdu Aircraft Corp.) decided based on their foreign users of F-7 suggestions on improving the overall maneuverability.
Thus, the J-7IV (later became J-7E) program started in 1987 and by May 1991, it made its first flight and 2 years later it came into PLAAF commission.
The main improvement was the maneuverability indeed, with the new WP-13 engine and the iconic double-delta designed by Northwestern Polytechnical University (西北工业大学 in Xi'an, Shaanxi) with a slat that can be lowered to 25° (and in fact the first PRC fighter with slats) that really helped its maneuverability- in a PLAAF's exercise in 1993, it was concluded that it was +43% better than older J-7II, as well as longer range with additional fuel tanks at the cost of giving up the port side cannon due to decreasing usage of cannons.
