MrVic: Churchill MK. Ic
Origins
The Churchill Mk I was a design started just after World War 1. Being originally designed for infantry support
it mainly focused on armor and the ability to cross trenches and crush obstacles. This outlook was starting to
change with the reports coming out of Poland when Germany invaded. Dr. H.E. Merritt was in charge of revisions
to the Churchill. He made a number of changes to the concept and design, one of these was the Churchill Mk. Ic.
With the need for a true tank hunter to use against the coming German offensive was going to be in great demand.
The problem with this was due to how narrow the chassis was, mounting a larger anti tank gun in the turret was not
an option. He had to think of a new way to get more space above the chassis. He settled on a angular reinforced
box almost resemebling a bunker. With heavy armor and the room to store more rounds of ammunition, combined with
the capability to mount a larger main gun he had his revision well on its way. While searching for a suitable main
gun he added a few revisions adding track guards and replacing the engine with a higher horsepower engine for added
speed. Finally he settled on the 3.7-Inch QF which was modified for his needs easily. The 3.7in QF would prove to be
a formidable weapon in the coming months. With this improvements in place he built the first 10 for testing.
The last stage of testing was to come in the form of german panzers cresting the horizon and then the production
order would be in great demand but time will tell.
