  1. 490A Rebel - competitor of 490 Poplar http://btvt.info/2futureprojects/490a.htm

    History repeats - in 1984 it was finally decided to chose 152 mm (490 and 490A were equiped with improoved 125 mm gun, like on Armata). Then they returned to 125 mm and will soon go to 152 mm.

    Tank Layout

    Partially survived - only the hull which was used to test molot engine. The turret was used for fire trials, so it has obj 476 turret and add onn plate to imitate weight.

    Tank Layout

    490A has crew separated from ammo, but has no blow off panels. late variant of 490A had also autoloader separated from crew only by a steel case.

    Tank Layout

    You are talking about obj 490, not 490A. Both 490, but completely different.

    Tank Layout

    The first version had "big ass turret bustle " for 1400 mm long round and charge, but then they - On subsequent version with a double-flow automatic loader with separate loading rounds was proposed. The projectile and charge were placed in turret bustle and hull sequentially (… round-charge-round …). http://btvt.info/7english/490_eng.htm This made loading a bit longer, but the turret bustle length was 2 times shorter.
  7. Development of future Soviet tank in 80-s and was a continuation of works started in 1970-s under designation “Project 101”. Necessity for development was grounded by the development of next generation tank in US and NATO. The importance of this task was well realized by Nikolay Shomin, a new chief designer of Kharkov design bureau, who replaced Alexander Morozov after he retired in 1976. The development of the tank had two main directions – conventional layout with 3-man crew and unmanned turret, which was known under designation “Object 490A” and later “Object 477” and unconventional 2-man design known as “Object 490”. The project “490” developed in the 80s was under development by Eugenie Morozov, son of the famous designer of tanks T-34, T-54, T-64 Alexander Morozov. The main features of the “Object 490” were: - crew consisting of two people - commander-gunner and driver. Reduce the crew to two people and place them in a compact, well-protected capsule. Depending on the specific layout, this gives a volume saving of up to 1.2 m3. - the use of hydro pneumatic suspension. In addition to solving the main problem - increasing average speeds by improving running smoothness, it allows to control the clearance of the tank, which increases maneuverability and survivability in battle. In addition, controlled hydro pneumatic suspension by changing the hull angle allows to increase the pointing angles of the gun in the vertical plane. - Creation of a special armored refueling and reloading vehicle capable of accompanying the tank in the same formation, overcoming hard natural and artificial obstacles, passing through nuclear contaminated areas of the terrain, and operating under conditions of use of nuclear weapons. In layout no. 1 and 2, it was supposed to implement the replenishment of ammunition and refueling the tank without leaving the crews of the tank and refueling-loading machine. Object 490 "Poplar". Unknown Soviet future tank of 80s http://btvt.info/7english/490_eng.htm

    Compared with the "Abrams", "Leclercs" and "Leopards" Borisov believes in strange VNIITM reports - http://btvt.info/1inservice/rarn_sravnenie2006.htm

    T-80 Megathread: Astronomical speed and price!

    The welded turret of such shape was really developed in 70-s
