XQ-5-LD Kingfisher (aka WS-427L, redesignated AQM-60A in
1962) only two serials (56-4054 and 58-1025) are known.
All together (X-7 and Q-5) 61 missiles were built, and
used for about 130 flights, most launched from one of
the following carrier aircraft: B-29B-60-BO, serial
'44-84073', B-29-55-BO, serial '44-86402', JTB-50D-80-BO,
serial '48-0068', and maybe another B-50, but about 6
were ground launches. At least 8 X-7s and Q-5s still
exist[/quote]

This is a general bump to see if anymore information turns up on that B-29. I found the following; but unfortunately not much more than what Scott has already said.
So evidently, two B-29's were modified to carry the X-7 and XQ-5's, plus possibly a B-50. If anyone had a photo of the other B-29; B-29B-60-BO, serial 44-84073 it would allow us to compare the two to determine:
1. Did the modification package include updating the engines also; or was that unique to 86402? Did the Martin Omaha B-29's use the Boeing Wichita wing join style at bodyline zero, or the Renton B-29A style which bolted the wing halves to a wing box? If it was the Renton style wing, then possibly the modification could have been a B-50 wing swap. The sole B-29D/XB-44 used these engines, but that was B-29A-5-BN 42-93845.
2. Was the tail cone consistent with both aircraft? It looks very much like the tail cone on the B-50's modified for the three hose and drogue refueling. More B-50 parts. Was 402 a composite of a B-29 and a junk B-50? Was there a purpose for the tail cone on the X-7?
3. What happened to the Aircraft Industries Museum in Louisville, KY? Is it still there? Not easy to find on the web. Was 86402 scrapped sometime after 1973, or does this exist as a display somewhere? The world wonders.![]()
Funny they would have scrapped one when others were recovering B-29's out of Aberdeen.

I'll see if I can clear up a couple of the questions. (Or make it even more confusing....)
1. Only Renton airplanes had the integral center section carry-through. All Wichita, Omaha, and Marietta airplanes have identical wings. The Andy Gump nacelles were not widespread, but they did appear on some special use aircraft, notably a few tankers. That leads into question 2.
2. That tailcone does indeed look like a tanker stinger. It is possible that '402 was a testbed for the tanker conversion program or was actually configured that way in "normal" service. We'd have to get the IARC to be sure. If you put the Andy Gump cowlings and the tailcone together it would appear that she was either a dedicated tanker or development KB-29 airframe before the X-7 assignment.
I haven't any idea on question 3, but I'd like to know what happened to these old girls too.
Here is a really interesting side-view of '073. http://wp.scn.ru/en/ww2/b/764/3/3/27
This is probably pretty accurate. I'm not certain if this airplane was assigned to the 315th Bombardment Wing or not, but several ships with higher serial numbers were. No tailcone mods either. I thought the JATO was an interesting addition, also!
The last time we were at AFHRA I discovered some documents pertaining to Superfortress use in the postwar period. The simple version is this: Strategic bombers (nuclear armed, via Silverplate or Saddletree) were to standardize on Boeing Wichita airframes only. The USAF hand picked low time airframes for this purpose, up to around 300 planes. All the rest, high time Wichita, Renton, Martin, and Bell were used for tactical bombers in Korea, tankers, parts donors, RB-29s, and all the utility uses. That is why you see a fairly large number of Martin and Bell airplanes modified for odd uses--the Bs and some Martin aircraft came from the factory sans turrets and other equipment.
