Stuart 18-Pdr: Improvised Honey
This improvised SPG was created by men of British 8th Army following operation Crusader in year 1941. Someone got idea to mount 18-Pdr field gun on top of Stuart light tank (which were often called Honey by British) with damaged turret to create self-propelled version of said gun and give damaged tank second chance in life.
There is no known technical data regarding this unique vehicle, but taking in acount time of its creation and what is known about both hull and gun themself, it is possible to quess aproximate statistics.
Hull is most propably from early Stuart tank due to time of creation being during North African Campaign, which would most likely mean hull of Stuart I. As Stuart I is already in game, stats such as engine power and general hull armor should be same for 18-Pdr Stuart.
Armor:
Front - 38.1 mm (18°) Driver Port, 15.8 mm (69°) Front Glacis,44.4 mm (21°) Lower Glacis
Side - 25.4 mm
Rear - 25.4 mm
Roof - 12.7 mm
Engine: 262 hp Continental W-670-9A
Max speed: 51 kmh (31.7 mph)
Unfortunately I dont know weight of turettless hull of M3 Stuart and thus I cant calculate power to weight ratio, but if turret weight was about 1/4 of tanks total weight and I added weight of 18-Pdr field gun, aproximate weight of this vehicle should be about 11-12 tons, giving it power/weight ratio of between 21-24 hp/t, but this is only rough estimate.
I would apriciate it, if someone would add any missing information in order to improve this post
Gun on other hand would be new addition to game and thus I will speak of it in more detail.
