The Best That Never Was 2 (Prototypes)

[Brit]

To be honest I put the T72/76 turret on as a) it was available / left over and b) looked 'ok'. I am interested that the T34/85 has a similar turret ring size but it seems like too much turret and too much gun. However having seen photos of the what has been put on M113s in the real world... I suppose it depends on how much stress the firing puts on the chassis / whatever?

PS. I did stick a Bradley turret on a standard M113... hence why I had a Bradley chassis spare.

I'm not sure if this has been posted, I couldn't find it.

Vickers Mark 11 6x6 Armoured Car

A failed bid for the Australian Bushranger contact, the Mk11 is a lightly armoured wheeled personnel carrier with surprisingly heavy armament. Development began in 1993 and the result is as follows:

Crew: 4+8
Mass: 20,000kg
Max speed (road): 105km/h
Max speed (water): 8km/h
Range: 1,000km
Armour: Proof vs mall arms (7.62AP) and shell fragments
Fuel cap: 500L
Armament:
L7 105mm cannon, 7.62mm MAG MG co-ax, 12.7mm M2 (loader)
or
120mm mortar or 81mm mortar, 12.7mm M2
or
20mm AA gun (unspecified), 7.62mm MAG MG co-ax
or
12.7mm M2, 7.62mm MAG MG co-ax (APC variant)

as well as the usual command, ambulance, fitter and so on variants.

Extra equipment: 350L water tank, centralized tyre pressure regulation system.

Oh, wow, can't remember I ever read about this one before. With a complement of 4+8 people and a 105 mm gun, this sure sounds cramped for a 6x6. Though this link speaks only of 7 dismounts, which would still be a regular number for armored infantry: http://www.military-today.com/artill...ckers_mk11.htm

Any knowledge as to why it failed the bid?

I'm not sure of the specifics, but it was out of contention early in the process. The prototypes the Australian Army ended up evaluating were the ADI Bushmaster (based on the Irish MP44) and the ASVS Taipan (based on the South African Mamba). It seems like the Vickers was out of contention by 1995 in the Bushranger Project tender process. If I had to guess, it probably didn't meet the 70% threshold for the requirement to be manufactured and built in Australia.

Ah, yes, that all sounds very likely, thanks.

The Royal Armouries released a video a few days ago on the BSA 28P. Rather unsurprisingly, Paul already has it in his Best Assault Rifles That Never Were, but the video mentions that the earliest prototypes did not include the cyclical rate inhibitor of the rifle that was written up. For serial number 1 (and an unknown number after, but probably no more than 6 because SN 7 has the inhibitor):

Change ROF from 5 to 10
Change burst recoil from 9 to 19

Yes, it's going to spit bullets everywhere but where it is aimed. Based on trials results, that seems to be historically accurate.

The write-up also mentions that it used rifle grenades. Per the video, the one it was designed around was the British anti-tank grenade No. 85, which was equivalent to the American M9/M9A1. It used a scaled-down bazooka-like shaped-charge warhead capable of penetrating 2" (~51mm) of armor.
