Gun Carrier 3-inch Mk I Churchill (A22D) by Uncle T

1,118 bricks.

My take on the British Gun Carrier 3-inch Mk I Churchill (A22D) Self Propelled Anti Tank-Gun. It is very much an approximation since it's based on my wheeled version of the tank that has been converted quick and dirty to using the new tracks.

Info from Wikipedia, somewhat edited.
*****
Coming out of a General Staff request in 1941 to investigate fitting high velocity large calibre guns on infantry and cruiser tanks specifically for use against German tanks. Of the infantry tanks, neither the Churchill nor Valentine could mount a turret with a high velocity gun larger than the 6-pounder, but it was proposed that a fixed superstructure could carry a larger gun with limited traverse.

The design used a fixed square thick plate superstructure with the gun in a ball mount low in the front next to the driver. The front was 88 mm (3.5 in), sides 76 mm (3.0 in) with overall weight of 39 tons. Internal stowage included a provision for 12 HE explosive rounds as well as the AP ones. The QF 3-inch 20 cwt anti-aircraft gun had been replaced by the 3.7-inch gun so these were selected to be used in the vehicle. I use 3 x AP and 3 x HE since it's a WW2 75 mm reasonably long barreled gun.
Gun traverse is +/-10 degrees, and elevation is -10 to +15 degrees.

About 50 were built between July and November 1942, but none are known to have been used in combat since by the time this vehicle was available the superior 76.2 mm QF 17-pounder was already in production and provided the necessary firepower for AT-guns and tank alike.
*****

The tank had a crew of 4: commander, gunner, loader/radio operator, and driver, but this is a single player version so everything is controlled from the driver's seat (front right hand side, it's British after all ;) ).

Controls.
Driver's seat.
WASD: Drive and steer.
L/Headlights: Headlights.
B/Beacon Switch between AP and HE ammunition for the main gun (indicator by the driver's seat).
Alt + Mouse/Key arrows: Gun traverse and elevation.
Fire action 1/Num 1: Fire main gun.

All hatches opened with button on or next to them.

Camera 1: Driver's periscope.
Camera 2: Main gun sight.

A few notes.
- The real Churchill had 11 double bogies, but since this is a rebuild of my old wheeled version I couldn't be bothered to add more wheels.
- The interior is low detail to save bricks.
- Reload time for the gun is about 5 seconds. A red light shows the driver that the gun is not ready to fire, and it's ready to fire once the smoke from the muzzle disappears + 0.5 or so seconds.
- The real top speed of this behemoth was only 24 kph/15 mph, but even a minimal engine power/max gear reduction the top speed of this one is closer to 40 kph.
