Description
The Su-7B is a rank VI Soviet jet fighter with a battle rating of 9.3 (AB/RB) and 9.7 (SB). It was introduced in Update "Starfighters".
General info
Flight performance
The Su-7B is characterised by a low BR for a supersonic jet and amazing acceleration. With a 1-1 thrust-weight ratio when at optimal fuel load and spaded, it can reliably punch above it's weight. The Sukhoi accelerates extremely well, outspeeding every supersonic at it's BR except for MiG-21s. The maneuverability isn't bad, either - It can easily turn with supersonics such as MiG-21s, Harriers or A-7s. However, you must keep in mind that the plane has a tendency to break it's wings if in a sustained 9+G turn at high speeds, and that you are not invulnerable while turning. You are giant, almost twice as big as a MiG-21, so be sure to not overstay your welcome in a dogfight and zoom away as soon as possible.

Armaments
Offensive armament
The Su-7B is armed with:
- 2 x 30 mm NR-30 cannons, wing-mounted (80 rpg = 160 total)
Suspended armament
The Su-7B can be outfitted with the following ordnance:
- Without load
- 64 x S-5K rockets
- 4 x S-24 rockets
- 28 x S-3K rockets
- 4 x 250 kg OFAB-250sv bombs (1,000 kg total)
- 4 x 500 kg FAB-500M-54 bombs (2,000 kg total)
Usage in battles
The Su-7B should be used as a missile with a man in it. Go fast, go for slow enemies (you'll meet plenty at your BR, you're the fastest plane after all!) and make sure to conserve your ammunition. A skilled pilot can easily get 3-4 kills with just the 160rnds of NR-30 ammo provided, but an unskilled pilot will have trouble hitting their shots. NR-30 cannons are (arguably) the best jet cannons one can have, and even a single hit can devastate an opponent. In conclusion, the Su-7B is a great plane, with amazing cannons and even better performance. Opponents will often underestimate you or even try to dogfight you, which can lead to a sudden increase in 30mm rounds in their fuselage.
Pros and cons
Pros:
- One of the fastest planes at its battle rating.
- Very fast acceleration.
- 2x 30 mm cannons are very powerful against ground and air targets alike.
- Decent energy retention.
- Time-fuzed S-24 rockets can be useful in headons.
Cons:
- Large silhouette, easy to hit.
- Decent ground ordnance, but nothing to write home about.
- NR-30 cannons expel ammunition quickly.
- No air-to-air missiles.
History
On May 14th 1953, shortly after Stalin's death and the reopening of the Sukhoi OKB, they began work on a swept-wing front-line fighter. Their first prototype was named S-1 and was fitted with the all-new Lyulka AL-7 turbojet. It was the first Soviet aircraft to utilize the all-moving tailplane and a translating centerbody, plus a dramatic wing sweep of 60°, irreversible hydraulically boosted controls, and an ejection seat of Sukhoi's own design. After the success of the S-1, production began with the S-2. later renamed the Su-7.
Later, on 31 July 1958, the Soviet Tactical Aviation tasked Sukhoi with developing a ground-attack variant of the Su-7, which could replace the scrapped Ilyushin IL-10. The resulting prototype, S-22, incorporated structural refinements for high-speed, low-altitude operations. It first flew in March 1959 and entered service in 1961 as the Su-7B.
Devblog
With the development of jet aviation, piston-engined attack aircraft quickly became an anachronism; a need arose for a new class of front-line aircraft - a fighter bomber. In the USSR, the MiG-15 and MiG-17 fighter jets were used to replace the piston-engined IL-10 to support the ground forces from the air, but it was quite obvious that a specialized machine was needed to fulfill the tasks of the fighter-bomber. The most suitable candidate was the Sukhoi Su-7 fighter jet, taken as the basis for the Su-7B fighter-bomber project. By the end of 1958, the first prototype was ready with the new AL-7F-1 engine. For almost two years, the aircraft underwent intensive testing and refinement, and in 1960 the new fighter-bomber went into mass production. Of the 431 planned, 344 Su-7Bs were built to equip up to 25 combat units. From the beginning of the 70’s, the Su-7B aircraft began to be replaced with more modern modifications and models.
