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.

  • 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

Main article: NR-30 (30 mm)

The Su-7BKL is armed with:

  • 2 x 30 mm NR-30 cannons, wing-mounted (80 rpg = 160 total)

The Su-7BKL comes equipped with 2 x 30 mm NR-30 cannons; these will be familiar to pilots which flew the preceding Su-7B, or the MiG-19PT and MiG-21F-13 in the parallel line. The Su-7 has greater ammunition capacity than earlier MiGs with the gun, 160 rounds giving a trigger time of approximately 4.8 seconds. With velocity ranging from 780-785 m/s depending on the shell, this is much faster than the earlier NR-23 or N-37D found on earlier Soviet jets. This greatly simplifies aiming, and with the 67.14 g of TNTe filler found in the HEF-I and HEFI-T shells, hits from this cannon will usually cripple or destroy enemy aircraft on the first hit. As the Su-7BKL is a strike fighter the guns may also be used against armoured targets; the mix of AP-T with 48 mm penetration and APHE with 37 mm penetration, but 22.48 g TNTe of explosive filler will do significant damage to enemy armour. It is recommended to attack from above, as most enemy tanks have weak roof armour and can be more effectively penetrated from above.

Suspended armament

Main articles: S-3K, S-5K, S-24

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

In terms of playstyle, the Su-7BKL is almost identical to its predecessor Su-7B. At the start of the battle in Air realistic battles, you can use your payload to attack strategic bases or ground targets, it gets easier compared to the preceding Su-7B, as the Su-7BKL finally has a ballistic computer for its bombs which will allow for better accuracy during drops. After the ordnance is disposed of, you may either return to base for rearming or try to engage enemy planes. When fighting with enemy players, remember to maintain your speed as it is your biggest advantage. Do not commit into extended dogfights as your manoeuvrability isn't the best compared to most fighters and you will bleed your speed quite quickly. While flying the Su-7BKL, you can also use your guns to destroy some ground targets, the NR-30 cannons will easily destroy light pillboxes and light/medium AI tanks when you aim at their sides or rear (your ammunition capacity is limited and you'll have to aim carefully if you want to destroy at least few of those).

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.

History

Main article: History of the Su-7B

The Su-7BKL is a further improvement of the Su-7B fighter bomber. The main goal was to shorten the take off and landing distances on both paved and dirt airfields, so the aircraft was fitted with rocket boosters to reduce take off length by 800 metres, and improved landing chutes with enlarged areas to decrease landing distance by 500 metres. Rear landing gear length was reduced and skis were installed to the wheels, in order to make unpaved airfield landings more effective.
