A development program to completely address the shortcomings of the BMP was started at the same time resulting in four prototypes, all of which had two-man turrets. Ob'yekt 675 from Kurgan - BMP-1 hull, armed with a 2A42 30 mm autocannon. This eventually became the BMP-2. Ob'yekt 681 from Kurgan - BMP-1 hull, armed with a lengthened 73 mm gun.
BMP (Ob'yekt 764) – The original main prototype of the BMP-1 was developed by the design bureau of the Chelyabinsk Tractor Works (ChTZ) and built in 1965. In comparison with Ob'yekt 765Sp1, Ob'yekt 764 was 4 mm higher, had a maximum swimming speed of 10 km/h, a lower maximum range (550 km on road) and a reduced number of firing ports for its passenger's armament (six).
The BMP-1, the predecessor to the BMP-2. Although the BMP-1 was a revolutionary design, its main armament, the 2A28 Grom and the 9S428 ATGM launcher capable of firing 9M14 Malyutka (NATO: AT-3A Sagger A) and 9M14M Malyutka-M (NATO: AT-3B Sagger B) ATGMs, quickly became obsolete.
Nonetheless, science and technology in England continued to develop rapidly in absolute terms. Furthermore, according to a Japanese research firm, over 40% of the world's inventions and discoveries were made in the UK, followed by France with 24% of the world's inventions and discoveries made in France and followed by the US with 20%.

It’s not possible to tell exactly what its adversary was—it could have either been a BMP-2 armed with a 30-millimeter autocannon, or a slightly better-armored BMP-3 with an additional 100 ...
The BMP-1 is unable to engage targets using the 2A28 "Grom" gun from some hull-down positions due to its limited depression, making it vulnerable to enemy fire. [8] The limited elevation of the main gun, its lack of firepower and inaccuracy against point targets at 500–700 metres (550–770 yd) meant that it could not fight effectively in the ...
The BMP-1AM Basurmanin is an upgraded version of BMP-1 developed by The Uralvagonzavod (UVZ) research-and-manufacturing corporation (a subsidiary of the Rostec state corporation). The BMP-1AM is BMP-1 with the original turret replaced by the turret from BTR-82A with a 2A72 30 mm autocannon , a Kalashnikov PKTM 7.62 mm medium machinegun, and ...
