A new, 4 man Medium tank featuring Medium RHA armor all around, with the armor at the front angled at 30 degrees. It features a fast-turning turret mounting a new lightweight, high-velocity 50mm rifled AT gun(the DT25) that is accurate, easy to reload, and features an interrupted screw breech and hydropneumatic recoil dampening (as well as a muzzle brake if necessary), as well as a coaxial belt-fed 1924 with another 1924 mounted on top of the turret in a pintle mount for anti-AA work. It has decent speed and a turbocharged, fuel-injected Diesel engine that puts out a lot of power for not a lot of fuel use and hydropneumatic suspension for a smoothish ride.
Autoloading cannons of this size are definitely going to be an issue to get working, but it looks like you guys want to hold off on that. Hydropneumatic suspension isn't an unreasonable design goal. Rocket launchers wouldn't be impossible to start working on now.
AS-T25: A medium tank, built to fit under medium thickness RHA. The armor is sloped shallow in the front, and this slope goes about halfway down the tank's length. The turret and crew hatch are on the flat part of the top of the tank, in the back, leading to a design that looks like a bit of a wedge. It is powered by a 12 cylinder, fuel injected, turbo charged motor. The new turbo charger is a super charger powered by exhaust, it provides the most benefit at high engine ranges. The Turbo is expensive, and the fuel injectors remain expensive and a bit fussy- their mechanical design requires a fuel pump for each cylinder and will probably remain expensive as long as they are mechanically controlled The turbo also increases fuel use. This combines to make the tank Very Expensive for its motor alone, but it can get up to 35 mph. The gun, a new AS-DT25, fires 50mm rounds, with a screw breech. It is fairly accurate and quite powerful. The turret is hand cranked and a bit on the slow side. It can fire about 20 times a minute and includes AP rounds. The treads are on hydropneumatic suspension, which improves accuracy while the tank is moving. Includes a coaxial AS-1924 and one on the exit hatch with a pintle mount. Costs 5 ore, 3 oil.
You have gained Turbo [Expensive]. Be aware that with its current motor, this tank is a national effort.
