Work on the welded turrets of Obiekt 187, Obiekt 188 (T-90) and the future T-80UD was carried out almost simultaneously. The tank was fitted with a new welded turret, unlike traditional cast ones, fabricated using steel rolled homogeneous armour (RHA). The same solution made it possible to arrange armouring at more rational angles of inclination as a countermeasure to modern sub-caliber armour-piercing rounds. This remedied a notorious weak spot of the T-64 design – the section between the turret and the hull. Due to lengthening of the hull's nose section, the driver's position was lower, with his optics attached to the roof of the hull, unlike in the T-64 and its derivatives. The redesigned layout took up more space, but positively affected ergonomics and protection from the glacis plate. A particularly notable feature was the rejection of the T-64 hull design. It was based on the T-72B, with a heavily modified turret. Obiekt 187 was a parallel project to Obiekt 188, the T-90 tank. Originally the design was intended to be only a temporary solution before the development of new combat platforms. The tank was fitted with cutting-edge systems and structural solutions, losing many of the traditional shortcomings of Soviet tanks. It remains a relatively unpublicized development because of high levels of secrecy surrounding the project. Object 187 ( Объект 187), was a Soviet experimental main battle tank developed between the late 1980s and middle 1990s.
