Description
The Su-7BKL is a rank VI Soviet strike aircraft with a battle rating of 9.7 (AB), 9.3 (RB), and 10.0 (SB). It was introduced in Update "Raining Fire".
General info
Flight performance
The Su-7BKL has the same flight performance as the Su-7B, with excellent acceleration and climb rate, along with decent manoeuvrability. The biggest advantage of the Su-7BKL is its acceleration and top speed, with a TWR above 0.8 across most flight regimes and fuel loads. This means that the Su-7BKL out-accelerates almost every aircraft at its BR, with the exception of Harriers at lower speeds. Top speed is just over Mach 1 at lower altitude, making the Su-7BKL faster than most aircraft it faces. Given its powerful engine, the Su-7BKL has an extremely impressive climb rate of almost 200 m/s. Given its acceleration, top speed and climb rate, few aircraft can keep up with the Su-7BKL in straight-line dashes.
The Su-7BKL's manoeuvrability performance is not as impressive. Its sustained turn rate at low speeds is competitive, but instantaneous turn rate and maximum angle-of-attack are both relatively low compared to its adversaries. This may make it more difficult to get guns on target. Additionally, some yaw instability occurs at medium speeds when pulling high-G turns. Finally, note that the Su-7BKL can break its wings in turns exceeding 9 G's, though this G-number isn't obtainable unless the aircraft is clean and carrying less than 20 minutes of fuel.

Survivability and armour
- The pilot is protected by light aluminium plates and an armoured glass windscreen. These will not stop 20 mm AP frontally, but offer decent protection from the rear.
- The engine is only protected by fuel tanks underneath. These can reduce the damage from shrapnel, but it is otherwise unprotected.
- The flight control's cables go underneath the fuselage, and have a good chance to stay in one piece when hit.
- The aircraft does not come with flares but has RWR. It will struggle against anything higher than its BR.

If you aim to play the Su-7BKL in ground battles, the first priority is to unlock the aircraft's anti-ground ordnance. The FAB-500 bombs and S-24 rockets are particularly helpful. Otherwise, focus on flight performance upgrades, starting with compressor, airframe, wings repair and engine. After those upgrades are researched and purchased, the other flight performance upgrades can be researched. The 30 mm ammunition belts can be researched last as the stock ammunition belts are quite potent.

Offensive armament
The Su-7BKL is armed with:
- 2 x 30 mm NR-30 cannons, wing-mounted (80 rpg = 160 total)
Suspended armament
The Su-7BKL can be outfitted with the following ordnance:
- Without load
- 96 x S-5K rockets
- 160 x S-5K rockets
- 6 x S-24 rockets
- 42 x S-3K rockets
- 6 x 250 kg OFAB-250sv bombs (1,500 kg total)
- 4 x 500 kg FAB-500M-54 bombs (2,000 kg total)
- 4 x 500 kg FAB-500M-54 bombs + 2 x 250 kg OFAB-250sv bombs (2,500 kg total)
- 4 x ZB-360 incendiary bombs
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).
Radars
The Su-7BKL is equipped with a SRD-5 rangefinding radar, located in the nose of the aircraft. It will automatically detect and lock onto planes within the range. It is linked with a gyro gunsight and can help with aiming at close range.

Pros and cons
Pros:
- Good horizontal flight speed
- Large variety of mounted weapons
- Powerful cannons capable of accurate strafing runs together with the ballistic computer
- Fast climb rate
- Good acceleration
- Has RWR
Cons:
- Mediocre controllability
- Subpar roll rate, even with the boosters modification installed
- No guided weapons
- No flares/chaff
History
Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
