Flightblogger has some interesting art comparing the Boeing KC-767AT and a possible “KC-764” based on the 767-400 at its blog here. The art looks at the tail strike issue, a potential problem for the KC-764 discussed by Boeing at the Farnborough Air Show.
Update, 1:40 PM PDT: Reuters reports that the Final RFP is now expected next week. It was originally due Friday, then this week. There is a third meeting between Boeing and the USAF/DOD (Northrop is taking advantage of these meetings as well). Boeing is pushing its position that (1) the original RFP specifications should be the governing document in this re-bid or (2) if there are changes, the company needs more time to consider another airplane, such as a tanker based on the 777F or 767-400.
Internet chatter about the prospect of a tanker based on the C-17 seems to be just that. A Boeing spokesman tells us he knows nothing of a prospective KC-17.
Update, 2:15 PM PDT: With all this talk about Boeing potentially offering a KC-764 or KC-777 (or even a KC-17), the obvious question that nobody has apparently asked until now is whether Northrop/EADS might respond with a tanker based on the A330-300, a plane larger than the A330-200 on which Northrop’s KC-30 is based.
Well, we asked Northrop. The response:
“We are back in a competition so the last thing we are going to do is tip our hand as to our bid strategy. Nice try.”
Update, 3:45 PM PDT Aug. 21: Reuters has this update, looking at the prospect of a Boeing protest.
