The Object 187 was a Soviet era program, developed to improve upon the excellent but ageing T-72 Main Battle Tank. Several prototypes were built, featuring a number of advanced elements compared to the older Soviet tanks, such as the new long 125mm smoothbore gun with a typical muzzle brake. The result was an excellent MBT that was, however, never mass-produced due to the 1990s Russian military budget cuts – the Russian army chose a less advanced but cheaper T-90 instead.
