Did you guys happen to note the link to the story about the US spy satellite that was shot down and fell in Peru? Check it out--its on the right side. It says the shoot down prevented us from nuking Iran or some such.
I've seen that pic before in a German Pz Div. book, can't remember which one right now. The T-28's armor was too thin, and it had reliability problems. There were some captured by the Finns in the winter war. They still have one in their armor museum. Hope I get a chance to see it in person one of these days.
Correct, at the beginning of the '30's the general attitude was that a breakthrough tank needed to be heavily armed but armor protection wasn't considered that important. The Vickers 16 ton tank was the genesis of the multi turrent tanks the Russians developed.
The original prototype had a 45mm gun as the main armament, but this was soon changed to a 76.2 mm 1927/32 gun. This was later changed to a 76.2 L-11 tank gun. It was powered by a 12 cylinder M-17L gasoline engine based on a BMW aircraft engine which developed 500 hp.
With the advent of more powerful anti-tank guns the T-28 was up-armored at the beginning of 1940 with more armor. The front of the hull and turret were increased to 50 - 60 mm the hull sides went to 40 mm. This increased the weight to around 31-32 tons. Vehicles with the longer gun and added armor were designated T-28E or T-28M. They saw action in some of the last battles in Finland in 1940.
The T-28 was produced from 1933 to 1940, with a total of 503 produced. By the time WWII started it's time as a viable tank had come and gone.
