CH53 sea stallion

I am looking for information regarding fuel burn rates on the above helicopter. I am able to get all sorts of figures relating to just about anything except what its average fuel consumption rates per hour is. Its a three engined beastie, so I imagine it uses more than the twins of that ilk, but any details would be greatly appreciated.

Big E fuel Burn

The following worked for me;
15 gal/min at 137% Torque
10 gal/min at 70% Torque
The flight manual has very specific charts covering climb, cruise and mine sweeping tow profiles (MH-53E).

Yes, it is US Gallons and it is not quite as thristy as the Skycrane. The Crane burns between 12 and 16 gal/min on just two engines.

I remember talking to german guys some two years ago at weston super mare where they had flown in in a German Army CH53 (unsure what designation) but it was a twin (two engine) and they told me their fuel burn was 1000 litres an hour with a total fuel capacity of 7000 litres. Whilst I suspected the three engine sea stallion would eb more, I am surprised by just how much more it burns by comparison.
