Biggus, that was my point!
As for refuelling helicopters, A400M
could do that, although I understand that the UK's won't have a tanker option....
When Sentinel was being developed, it was originally to have had a probe. But a chap from Boscombe, who was in the know, told me that it barely met its target spec without a probe and adding one would have been the straw on the camel's back.....
Many of us have had many, many VC10K AAR sessions with the C-130. Usually boring as hell and the hose would often run in at the slightest nudge of foreplay. But I did once refuel a C-130 in the hold at KKIA during Gulf War 1 as we waited for the cloudbase to lift. He would have lost his mission slot if he'd had to land to refuel, so he took some off us, landed when the cloud liftes, offloaded his cargo and was off again in time to meet his slot. It caused much mirth amongst the air traffickers!
