Description

The Su-7BMK was devised almost immediately after the Su-7BM variant, as a downgraded export version for overseas customers outside the Warsaw Pact, being sold to many overseas customers including Egypt, India, North Korea, Algeria, Afghanistan, Iraq, and Syria. The primary users of the BMK were India and Egypt, both of which successfully used the aircraft in active combat. The BM (and its export variant, the BMK) provide multiple upgrades over the older Su-7B variant. Primarily, the aircraft were fitted with the more reliable and powerful Saturn AL-7F-1 engine and "wet pylons" under the wings, allowing the aircraft to use external fuel tanks.

The Su-7BMK was introduced in Update "Red Skies" as a pack premium, and was sold until the 2023 May Sale when it was removed from the Gaijin Store. Afterwards, it was made available again for two days due to its flight anniversary on January 24th 2024. Being an export version of the upgraded "BM" variant with many upgrades over the Su-7B in the tech tree, but without all the extra weight of the rough-field operation kit found on the tech tree Su-7BKL, the Su-7BMK is arguably the best Su-7 variant in-game, though all the Su-7s suffer from major issues at their battle rating, including lack of proper dogfighting performance, countermeasures, or any real air-to-air weaponry in air battles, and very underwhelming ground attack ordnance compared to their adversaries for ground-strike roles. All in all, the Su-7BMK is still a unique premium and is very efficient at researching aircraft due to its high speed, allowing it to bomb bases in air battles quickly and escape before enemy fighters intercept it.

The pilot is well protected from shots, with a 102 mm bulletproof glass front windscreen in the cockpit, an 8 mm steel plate in front of the instrument panel, and a 5 mm steel plate above the windshield. There is also some armour protection from behind: 36 mm Aluminium Alloy plates for the seat and a 20 mm Aluminium Alloy plate for the headrest. There is no protection from shots coming from the sides.

Arcade battles

The Su-7BMK can bomb bases, intercept bombers, and fight other fighter planes at the same time. You can easily catch up with the enemy because of the massive and powerful engine with its afterburner. However, keep an eye on the fuel; the afterburner burns a ton of fuel when active, so if you plan on actively using it, it would be wise to fill the fuel tank up to full. The plane also features a ballistic computer and two 30 mm autocannons, with excellent ammo selection, which can rip apart any plane you'll face in battle. The Su-7BMK can perform well in a 1-vs-1 scenario, but if it encounters multiple enemy planes, it will have problems (especially if your enemy is equipped with air-to-air missiles). The best strategy is to have a teammate close to you, so you will have some cover if things go wrong.

Realistic battles

Dogfighting is not viable because of the poor turn rate; the enemy can out-turn you quickly and get behind you. The Su-7BMK is an interceptor/attacker with a slow roll rate. Because of the low ammo capacity of the guns (160 rounds), pilots should apply strict trigger discipline. The two 30 mm autocannons are potent and can quickly destroy most planes that the Su-7BMK fights. Remember to use short, controlled bursts since the ammo belts are short. Overall, the Su-7BMK should remain an interceptor and a base bomber. With its ballistic computer, pilots will obliterate ground targets and bases.

Pros and cons

Pros:

• High flight speed and rate of climb
• Retains energy very well
• The 4 x 500 kg + 2 x 250 kg bombload allows for efficient bombing
• Its speed lets you quickly reach bomb targets and return to base for rearming before enemies can get to you
• Radar Warning Receiver (stock)

Cons:

• Decreased manoeuvrability at high speeds
• Lacks guided weapons: neither AGMs nor AAMs are available
• Wings can be ripped apart if one isn't careful when diving on bomb targets
• No countermeasures
• Practically restricted to ground operations
• RWR covers only very few bands and hence does not show any radar ping or lock warning for most enemies

History

The Su-7BMK was a simplified export variant of the Su-7BM. The fighters were produced from 1967 to 1971 to more than 400 units and exported to Egypt, India, Algeria, North Korea, and Afghanistan. The Su-7BMK is identical to the Su-7BKL except for its landing gear, IFF system, and ballistic computer.
