The M103 Heavy Tank was developed post WWII and put into service beginning in 1957. This tank was the largest and most armed tank that had ever been developed for the US Army and USMC. This huge piece was developed during the Cold War Era to meet the challenges of the heavy tanks developed by the USSR.
The USMC acquired 220 of these tanks for supporting their infantry units, while the US Army acquired 80 of the tanks. A total of 300 were built. None of these tanks were ever used in combat.
The extra-large 120mm cannon required that the turret be larger than the M48 or M60 tanks to accommodate two loaders, plus the gunner and commander. The gun could be elevated between 15 ᴼ+ to -8ᴼ degrees.
Many additional modifications were made and shared with the M47 and M48 Patton tanks and the M60, which were all medium tanks with 90 or 105 mm guns. Two additional variations that were developed included the M103A1 in 1959 and the M103A2 in 1964. The M103 was very underpowered and the transmissions were fragile, thus this tank never had enough power to operate properly. The United States withdrew this tank from service sometime in 1974.
Quite a few of the M103s can still be found on some US military bases, while others can be viewed at various museums throughout the United States.

don't you just miss the heavies? the Russians should really make a new one, one made from melted down t-80's they have loads in their scrap yards... melt them down to produce something really big, heavy, reliable, and most of all Russian
I have a few M103s and Conquerors.
I've stood next to the one here on FT Hood the thing is huge,and the Conqueror is bigger!
Yes the British tanks are always a bit bigger than ours, I put it down to the fact that they have not been happy since they stopped building Dreadnoughts. ;-)
I'm with you there Gowan! Easier to target ;-)
You might just have something there Bill!
A proper big silly tank! Not as impressive as a Conqueror obviously.....
Tim that's only because the Conqueror longer and wider...)
Thinking of putting up some side by side photos of my ROCOs of both.
Comparison pics would be a good idea. Somewhere I have a 6mm M103....
I'll get them some time today.
