90mm HVAP by Mad Missouri
Aberdeen Proving Grounds
September 2nd, 1946
Well Sir, what do you think?
That Major is a most impressive test fire. What ammunition type was that? One of the 90mm HVAP rounds?
No, Sir. That was one of the new M99 90mm Armor Piercing Discarding Sabot rounds. We copied the technology from the British. Our first two attempts did not work very well, but the M99 has passed every test and went in to full production the middle of August. It was decided not to send it to our Divisions in Spain, so it’s sure going to be complete surprise to the Russians come spring. The Armor Forces Board was so impressed they asked for 30 rounds per tank for the upcoming operations. That’s half the ammunition load of a T50 Patton tank.
With the way this war is going, I doubt anything we do is a surprise to the Russian. But it sure made short work of that T34/85. What made the turret roof blow off like that?
The ammunition in the turret cooked off, Sir. We set the test tank up with what we think is the normal combat load of fuel and ammunition. Our technical intelligence teams in Spain have been sending back a lot of useful information and captured equipment. It’s seems to be a major design flaw in the T34/85; the Russians used that extra space in the turret rear to store ready ammunition.
