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
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
Pros:
- One of the fastest planes at its battle rating
- Very fast acceleration
- With S-24 rockets you can win every head-on
- Able to zoom climb up to 8,000 m
- 2 x 30 mm cannons are very powerful with Armored targets belt
- Decent energy retention
Cons:
- Huge plane and very fragile
- Underwhelming manoeuvrability
- Very unstable
- Below average roll rate
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.
