The SU-100P (Object 105) was a Soviet prototype self-propelled howitzer. It was the main competitor to Object 416, which was being developed at the same time. One of its standout features was the D-50 anti-tank cannon, which was a modified D-10 with a higher muzzle velocity and was specifically designed for the vehicle. However, flaws in the design were discovered during testing. Notably, the gun, chassis, lifting mechanism, and a number of other components were discovered to be unreliable, causing numerous issues. As a result, the SU-100P faced significant challenges and required an overhaul in design to address these issues and improve its overall performance. Although the SU-100P was making significant progress, the project was ultimately canceled due to Khrushchev's views on the future of tank warfare, which did not see self-propelled guns as a viable option. But its potential wasn't fully wasted, as the chassis of the SU-100P was the basis of many other designs.

The SU-100P was introduced in Update 1.71 "New E.R.A.". Like most other Soviet tank destroyers, it is best used as a sniper. On the other hand, because of its mobility, it can easily access areas where other tanks might struggle, making it well suited for flanking. Those looking for a powerful and accurate gun will not be disappointed either, as this vehicle is equipped with a D-50 100mm anti-tank cannon, which is a modified D-10. Overall, the SU-100P is a highly capable and versatile vehicle.
