Coming soon to the Supertest is the ISU-152K, a Soviet Tier VIII TD.
Its outstanding feature is the 152-mm BL-10 gun, which boasts high armor penetration and an alpha of 750 points. The basic round can pierce 286 mm of steel while the special APCR round can break through 329 mm. The gun’s accuracy is not that impressive (0.41) and neither are its aiming time (3.4 seconds) or rate of fire (3.16 shots per minute).
In terms of protection, the ISU-152K is on par with its researchable counterpart the ISU-152, with 90 mm of armor at the front of the conning tower and an HP pool of 1,200 points. The dynamics are similar with the ISU-152K having a top speed of 40 km/h and a specific power of 12.7 hp per tonne of weight.
All in all, the ISU-152K is very much like its tech tree ‘relative’. The differences with the researchable TD are subtle: the horizontal firing arc is a bit wider, the armor penetration of the gun is a bit higher—at a cost of slightly lesser mobility and a slightly longer reload time. You don’t have to adjust to this vehicle as its play style is familiar to the majority of tankers: an ambush TD with high one-time damage.
