KC46 program status

This is a little hard to understand.  Did all the engineering talent go to the 787 program?  How do you not get wire harnesses right the first time? The APU wont start thr main engines--after building 1200 commercial variants?

There are Boeing tanker 767s flying (modified by Boeing) in Italy and Japan  at this moment.  That's what's kinda hard to understand.  Of course these don't have the 787 cockpit which I'm sure is vital to the mission.

Isn't it basically new design except for the fact it looks like a 767?  I doubt the Air Force wants a commercial airliner with bolted on equipment.  Gotta have the best for them you know

As someone who hasn't studied the KC-46 in the least, what advantages does it offer over our old legacy KC-135s and KC-10s (besides the obvious low hour new airframes).

And what does it offer over our allies' KC-767 to justify the additional cost?

I believe this is the point(s).  The ancient airframes issue can't be avoided. We're polishing the turd here, not materially advancing capability.  What marginal increase in capabilities the KC46 offers over the KC767, I've never seen although it may have been published somewhere, given that the KC767 has hooked up to B52s, in addition to to most of the othet aircraft requiring either boom or drogue systems, I suspect that the capibilities of the KC46 are only marginal.

There is precedent - the AF paid money to have beta removed from the t6.  

With tankers always operating from major air bases it's easy for a desk jockey to rationalize it - "there's plenty of runway, in case of trouble just use up the brakes and replace them.  Current bases are adequate for wheel brake only aborts so the TR is not required.  ".

We have a local group of KC-135R's near the house. My stepfather worked on them for more than 30 years. As he's told me, the airframes are getting OLD FAST. Thankfully the NH ANG will be one of the first with the KC-46. Here's hoping Boeing gets it right.

Cool picture! I know the 135s are getting ancient and need to be replaced. I just don't understand what new capabilities the KC-46 brings to the fight over the KC-135s or KC-10s, besides being brand new. If Boeing has already designed the KC-767 for sale to our allies, what outstanding capabilities does the 46 possess to justify the massive price tag compared to the already developed KC-767?

At least with the super expensive F-22 and F-35 programs there is a list of new capabilities over the legacy platforms a mile long.

From just standing back and looking at this KC-46 program it's almost about the same as paying Boeing billions to design a completely new airframe for the Air Force One replacement when all we needed was to modify an existing airframe.

Except they burned through brakes like crazy till they installed the new $$$$$$ carbon fiber ones.

A brake would last up to 2 yrs on a E model with TR's , on a R model a non carbon fiber brake would be lucky to make it 4 months.

To not put TR's on the new KC-46 is idiotic but we are dealing with the USAF after all.......

The whole wiring harness BS is another The plane is never going to be shot at and if it is , separating the wiring isn't going to make a difference....

While I see the point of questioning why they didn't go with the K-767, I'm scratching my head over your questioning the value of a new airframe to replace the KC-135's and -10's.  Neither of those airframes are in production anymore - it doesn't matter if a new tanker exceeds the old specs - new 135 and 10 airframes are simply not available.  I have yet to meet a modern car as fun as my old Karmann Ghia convertible, but if it crashes, there IS no replacing it with something "the same, just newer."

I'm not questioning why a new airframe over the 135 or the 10. I know they are old and the production line and tooling, etc are long gone and there are new technologies now that make those old airframes obsolete. The KC-767 is more than likely "the same, albeit newer" and more efficient.

And while we are comparing capabilities, what does the KC-46 do that the 135 and the 10 can't do? And comparing apples to apples, what does it do that the KC-767 can't do?  It just seems like instead of purchasing the KC-767 the US has spent billions redesigning the wheel.

At least if you ask what the F-22 can do over the F-15, the list is extremely long and it's capabilities are outstanding.

It's about like the Airforce putting out an RFP for a C-130 replacement, and then spending billions of dollars buying a new airframe and program that does the exact same thing as the C-130.  (I know my analogy isn't perfect as the C-130 production line is still open).

The contract over-run ($1.5 billion) comes out of Boeing's hide.  Boeing announced shortly after contract award that they had purposely underbid the contract well
before the money had been spent.  And what general retires on $750k/yr?

More or less this.  Wiring issues, re-routing hydraulic lines, ducts, etc, due to added longerons, spars, etc added to beef up the airframe for a higher gross weight than the passenger 767.  "Off the shelf" 767 parts won't all work so they're essentially making it up as they go.



Much like other recent projects such as the C-130 AMP, it sounds all well and good to take an old airframe and integrate totally new technology from the civiilain sector into it (like the 787 flight deck into a 767, or 737 FMS into a C-130).  However once you get actually dig into it you realize that it's not easy at all fit a round peg in a square hole. The engineering challenges are significant. This will all get figured out, after delays and cost overruns of course.

I'm not surprised that if the KC-46 is ever fielded and meets the AF requirements as reflected in the RFQ, it will exceed some  capabilities of the KC767.
The point is that they both are 767s with the KC46 being the polished turd version. It can only be marginally better.  Are the marginal advantages in certain metrics of the KC-46 (whatever they are) worth the extra time and treasure? I'm not in a position to know, but given the history of airplane procurements over the past twenty years, a little (or maybe a lot) of skepticism is warranted. Not that it will do any good.

Amazing, I'm reading that in Jim's voice.  He was so frustrated with the powers that be on this software being chosen and shoved down the designers throats.  Of course, after all these years, I don't recall any of the technical details but I sure remember his frustration with it!

As I understand it was so that we didn't have to spare left and right engines.  I would think that putting CFM-56-3s on instead of -2s would have been a better choice since they have TRs, a higher ground clearance, and a lively civilian market to keep the supply chain running better.
