Hi TP
In reply to your earlier Post.....
I disagree. The Brits, Israelis, US and new European (Leo2 and Leclerc) opted for more armor, and then the gun engine as big as it's possible.
The Brits wanted the heaviest armor most notably, and their most successful tanks were the ones with the heaviest armor available. From Matilda on.[/I]
Doesnt explain why postwar tanks actually dropped in weight relative to the end of war heavies being designed and built by the major combatantsat the end of the war.....the tiger II weighed over 150000 lbs, the IS-3 were about 115000, the British Tortoise were 174000 lbs, the Pershings were about 95000 lbs. The Maus represents the "next generation" of the "Heavy Tank" design and had a weight of over 410000 lbs!!!
Compared to this the 1st generation postwar tanks were actually lighter in many cases, but were far more mobile and carried a far heavier armament. The Leopard I weighed 93000 lbs, the AMX-30 about 80000 lbs....Soviet Tanks were about 90000 lbs. Second and third generation tanks are still about 83000 to 145000 lbs, with some nations abandoning the armoured component almost entirely and producing light vehicles under 40000 lbs (such as the Brazilian X1A2).
Whilst todays MBTs are beginning to approach the weights of the end of war heavies, they do not by any means represent the "heaviest armour" that can be installed into the design. The difference is in the power to weight ratios....modern MBTs typically are powered by engines in the 800-1500 hp bracket, whereas the end of war "heavies" were powered by engines in the 600 hp bracket. On the basis of engine power, which was one of the major constraints to heavy tank development at the end of the war, there is no reaon that I can see to prevent tanks in the 2-300000 lb range...But countries dont do that, because the Heavy tank concept cannot fulfil all the functions of mobility, and firepower is far more important than protection, and simply because tanks of that size and power would be prohibitively expensivei
The most expensive part of armor unit are not the tanks themselves, but the trained/experienced crews. If one puts them into the tinclads, the result would be disastrous in any war against a tough opponent.
But, since the bean counters (politicians) control the armed forces, for most of the countries the cheap tank is a good tank, so that's why T-55/Leo1/AMX-30 were so popular during the cold war.
Err only half true. The cost of a Panther Tank was RM 176K, whilst the cost to train its crew to a high standard was about RM 135K. One could reasonably expect similar costs for the other medium and heavy tanks produced by Germany .
By comparison, the cost to train a Soviet T-34 Tank crew has been estimated at under RM 10K, whilst the cost of the tank itself costs about 25K. I dont know the crew training costs for the US or the british, but I expect it will be less than the Germans, because training times were shorter (about 7 months, to about 9 months, and the costs of fuels, accommodation, and just about everything else you can think of to support the crew whilst they are being readied was cheaper for the allies. The Americans in particular got the training regime for their various specilaist arms (including tank crew training) down to a fine art .
So it is just not true that the crew training costs are more than the cost of the hardware. It varied massively from nationality to nationality, but consistently it was less than the cost of the hardware.
And lastly, the tanks you mention as being the products of political intervention (AMX-30 etc) were in fact representative of every modern tank of their era....I know of no tanks that tried to outweigh these tanks to any significant extent....even the Chieftain was only moderately heavier at 120000 lbs, and in my opinion suffered serious mobility issues as a result. It was not a case of nations penny pinching, rather it was a case of nations relaizing that numbers do count, mobility does count, andd making tanks too heavy simply makes them expensive, imobile (and unable to be moved across the existing infrastructure) targets in innsufficient numbers
