Not surprising considering the gun this thing packed

When looking at a Tank vs a Tank destroyer, remember that the engineers usually had to compromise the guns size so as not to overtax the turret ring, plus make room for the crew inside.
Tank destroyers got around that by pretty much doing away with the turret and building a box on top of an existing hull. This allowed a much larger gun to be fitted inside without major alterations to the basic production line hull of the existing tank.
The Elephant Tank Destroyer fielded by the Germans for instance, pretty much built an armored cupola on top of the hull of the Tiger (P) Variant (Built by Ferdinand Porche under contract competition with Henschel, Henschel won and produced the Iconic Tiger so many are familiar with)
SU-152 and the later ISU-152 were built up off the Kliment Voroshilov, or KV series heavy tanks.
Another Tank Destroyer, dubbed the JadgTiger, used the hull of the King Tiger, or Tiger II tank.
Pretty much they were just tanks used to carry super heavy guns around
