Franken-AFVs

[StainlessSteelCynic]

One of the most important things to consider here is turret ring size. Will the borrowed turret even fit the vehicle? Will you have to make a new deck & turret ring to fit the borrowed turret to the hull?
After that are the various requirements for turret rotation (mechanical, electrical, manual, etc. etc.) and installing the needed components.
Before that you have to find out whether the vehicle (or turret if giving it a different weapon) can handle the recoil of the weapon because that would mean extra gear to counter recoil forces.
Then there's the ammunition feed & storage. They will have to be changed to accommodate the different ammo requirement.
If you're just cramming a different (and larger calibre) weapon into the vehicle's standard turret, how crowded will this new weapon make the turret?

It's for all these reasons that I suggest making this sort of conversion a side-adventure for any Players who want to convert a vehicle. Finding a vehicle already converted is a different situation and I'm not attempting to address that.

An excellent post - and would make an interesting exercise for the players and the GM to thru as a way to have to gather the materials and expertise to do that - let alone the facility you would need to be able to do something like that

I could see players who are adventuring in CA possibly doing this in conjunction with the facility that Littlefield had - i.e. if anyone has the expertise to make a working FrankenAFV its him and his mechanics - and they had the facility - now its up to the players to get the parts he needs

One swap that should work for turret ring size is Abrams/Chieftain/Challenger 2/M48/M60 and probably T-72/T-80. The NATO tanks all have the same diameter, as do the two WP tanks, and there's only 3mm of difference between the turret ring sizes between the two groups. The T-64 probably won't work, because its ring is 2.245m instead of 2.159/2.162m, nor will the Leopard 2 with its 1.980m turret ring or the T-54 at 1.825m. There would be issues with the autoloader or lack thereof if swapping between NATO and WP.

I'm not sure what the turret ring diameters are for Leclerc, K2, Type 90 (Japan), or China's Type 80/88/85/96 or Type 99.

Okay here you go its M113/TS90

Thanks for posting that image.
I have to say, it kinda looks "wrong", as in, the turret look too big for the hull - like seeing a fat head on a tiny body kinda wrong (and not photoshop kinda wrong)

The M113/LS90 looks less top-heavy, since it uses a smaller LP90 turret from the Cadillac Gage V-300/LAV-300 with a Cockerill Mk. III gun. It's quite a bit smaller than the GIAT TS90 turret with CS90 gun. Ammunition stowage was 42 rounds, and the fully equipped and crewed turret weighed about 4900 pounds.

Australia had a number of turreted M113s that loosely fit into the Frankenvehicle concept - they were standard production, but cannibalized parts from vehicles being retired. I expect the Australian board members will know more than I do, but my understanding is it started with an interim fire support vehicle that had the Saladin armored car's turret added, giving the M113 a 76mm and .30 coax. It was replaced by the medium fire support vehicle with the FV101 Scorpion's turret, also 76mm and .30. There was also a light fire support vehicle with the T50 turret from the Cadillac Gage V100/V150, which had a .50 and a .30. Troops were generally equipped with 3 light and 2 medium support vehicles.

That's more of a roll hazard than a 577...

That really does look too much turret on too little a vehicle... but...

Go with me on this but the WWII Matilda tank turret to me works on the M113. I know I stuck one on one...

The WWII, etc, Stuart turret 'works' too...
