(2/24) The Kobra KUV's history is a bit long and complicated, dating back to the unsuccessful Rubin missile of the Object 431 from 1957 (shown here). Developed under Aleksandr Nudelman, prior to 1966 it was known as 'Gvozd' ('Nail').
(3/24) Before we continue, it should be noted that the GRAU had (has) different designations for missile complexes and their components. Sometimes the missile itself might have a different name to the complex as a whole. This can lead to confusion.
(4/24) Example: strictly speaking, '9K111-1 Konkurs' refers to the entire system consisting of the 9M113 missile + 9P148 (upper) or 9P135M (lower) platforms combined.
(5/24) The 9M113 missile itself has the name 'Gaboy', but this name is so obscure today that most people just call it 'Konkurs', after the entire complex.
(7/24) The T-64B1 does not have Kobra KUV, and hence lacks the GTN-12. However, T-64B1s are, to use the naval term, 'fitted for but not with' the Kobra KUV and can be given it if desired.
(8/24) The Kobra KUV consists of many components, of which the GTN-12 is only one. It also technically includes parts of the 1A33 Ob SUO, and they are integrated as the Ob-Kobra complex.
(9/24) The Kobra KUV relies on radio-command SACLOS (semi-automatic command to line-of-sight) guidance. It is aimed using the 1G42 sight of the Ob SUO. The gunner must keep his sight on the target until impact, and the system will correct the missile onto his LOS.
(10/24) The 9M112 Kobra missile has an onboard modulated light source, which is tracked by the ZGTN-25 photodetector integrated into the 1G42 sight. Corrections are then sent by the system to the missile through the GTN-12 antenna, completing the SACLOS loop.
