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-4 was outfitted with the following offensive armament:

• 1 x 37 mm N-37D autocannon (40 rounds total)
• 2 x 23 mm NR-23 autocannons (160 rounds total)

Suspended armament

The J-4 can be outfitted with the following suspended ordnance:

• 2 x 250 kg OFAB-250-270 bombs (total = 500 kg)
• 16 x S-5K rockets
• 16 x S-5M rockets
• 2 X S-21 rockets

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

Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".

History

The usage of the designation J-4 is unclear, though most western observers claim it was applied to either the MiG-15 or MiG-17. One theory suggested that J-4 was the Chinese designation of the MiG-15bis, though this was later debunked when it was found that the J-2 was in fact a 15bis model. The most likely theory (and the one followed in-game) is that the designation was applied to imported Soviet-built MiG-17As, while license-built MiG-17Fs were designated Shenyang J-5 (F-5).
