A number of A330 tankers will be 3-point hose-and-drogue tankers.
As for tactical AR, particularly for helicopters, Sir might be interested to know that the A400M Common Standard Aircraft has to be capable of being re-roled into the AR role in less than a day. Extra cargo bay tanks can be fitted, but with those on board it doesn't leave much grunt space!
A330 MRTT 111 tonnes of fuel
A310 MRTT 72 tonnes of fuel
A400M (2 x CBT) 62.1 tonnes of fuel
A400M (1 x CBT) 56.4 tonnes of fuel
A400M ( Basic ac) 50.6 tonnes of fuel
And some lucky lads and lasses currently going through ME training will have the fun of flying them! Enjoy!
Hi Westie! At a guess I'd say the European A330 MRTT will fly first. Incidentally, our A310MRTT has already flown, shall be casting an eye over her this week.
