Chieftain Tanks at Duxford 2009

Chieftain Tanks rolling in the sand pit at Duxford 2009, Check out the prototype with twin 30?mm AA Canons. The noise of the engines scared my 2 yr old so bad he is still going on about the tanks months later. Put the volume on full and you'll see what it feels like to be a few yards away from them!

Know what you mean, I think its the noise the engines make as if they are being thrashed

With that 2 stroke design it's no wonder they had so many break downs, they're relying on engine horsepower and not torque to move the machine. Sounds much like a GM diesel or Detroit diesel engine.

@ak907jk The engine is a 6 cylinder, 12 piston engine. Two pistons horizontally opposed in each cylinder. The tank was slow, but even worse was the engines 90% failure rate

Weighing in at a combat weight of 121,250lb or 55,000kg

Running on a Leyland L.60 No4 Mk8A 12-cylinder multi-fuel engine developing 750BHP at 2,100RPM with a top road speed of only 30MPH I would say yes these tanks have incredibly underpowered engines their power to weight ratio is way off lol

[Acornoa]

do these tanks look underpowered to you, or is it just me?

The "prototype" Chieftain was a Marksman Mobile Anti-Aircraft system adapted to the Chieftan from the T-55 & T-72 versions
