MISSION STATEMENT

This website is to serve as a catalog of historical information for various tanks, across various stages of development, created for use by the United States from Pre-WWII through to the 1970s. However, the primary purpose for this website is to illustrate a proposal for what an "endgame" could look like for the US tech tree in the game, World Of Tanks, and to show that there's still plenty of life left to breathed into this game.

My aim is to see as many tanks in the game about tanks as possible, and I hope to show that in a way that respects both the historicity of the tanks shown and the balance of the game overall. As such, I will not be going into great detail on individual statistics. Rather, I will only be showing the possible modules for each tank, changes that could be made to make it more historically authentic, a historical overview, and how the tank's playstyle may be represented in-game. I will also attempt to future-proof this by including alternate hulls, half-tracks, and wheeled vehicles.

This is certainly not perfect and everything is subject to change. This is still a work in progress, and updates are frequent if not daily. This is a fan project and a labor of love. Do enjoy.

AGS-M551


By the early 1980s, the Army concluded a more powerful weapon than the 75 mm gun required by the HIMAG program was necessary for the Army's light forces. Characteristics were outlined and revised, becoming known as the armored gun system (AGS). The search for a new weapon considered a 105 mm gun to be the most ideal candidate.

 The Naval Surface Weapons Center experimented with installing the 105 mm Gun M68 in the turret of an M551 Sheridan and using the recoil system for the 152 mm gun-launcher. The cannon was trialed with and without a muzzle brake. Although this installation worked, it would have required significant development before it was satisfactory. The turret ring in particular couldn't quite handle the recoil force of the massive weapon and was damaged after some tests. However, it was deemed practical to mount a 105 mm on such a lightweight chassis. The development of such a new AGS was designated as the XM4, and several potential candidates were put forth.

 The Cadillac Gage Company had been developing the Stingray light tank for the export market, but quickly realized it met the requirements for the XM4 program. It had a welded turret with a conventional crew arrangement. The gun used was a low-recoil force (LRF) variant of the Royal Ordnance 105 mm L7. The turret and gun were successfully tested on the chassis of an M551 Sheridan.

As I'm proposing it, the AGS-M551 is a combination of both of these projects. While this is technically a light tank, I think the stresses provided by the gun on the chassis makes it more in line with this particular branch of tank destroyers. The vehicle is extremely mobile, but I would expect the aim time, reload speed, turret traverse, and on-the-move dispersion would be relatively poor. This makes it more ideal for the tank destroyer role in my opinion, especially as the requirements of the AGS is comparable to the theme of this mobile, lightweight branch of tank destroyers.
