Highest Alpha Damage Tank Destroyers – Tier 9
T95
At Tier 9, the American T95 offers an incredible amount of frontal hull armor and a gun mantlet that is downright impenetrable, but more important is its gun. The 155 mm AT Gun T7 is the final armament available for this Tank Destroyer and improves its alpha damage to the tune of 750 and ups the penetration to 276 mm.
T30
Another United States Tank Destroyer finds its way onto the list in the form of the T30. This once Tier 10 TD has dropped to Tier 9, and despite nerfs, manages to remain a terrifying vehicle to face. When equipped with the 155 mm AT Gun T7 (the same as the T95), the T30 can dish out 750 damage on average with 276 mm of penetration. This is truly one of the best Tank Destroyers in one of the best USA tank lines.
Object 704
One of the few Tier 9 Tank Destroyers that can match the sheer power of the ISU-152 is the Object 704. This TD is essentially a straight improvement over the previous vehicle, except for its speed limit. Despite this, the Object 704 is able to remain hidden, aim faster, and fire with more accuracy. With the same gun as the ISU-152, the Object 704 deals the same damage: 750 alpha with 286 mm of penetration.
