Employees in Wichita recently began production on the first Boeing KC-46 Tanker parts, destined to be integrated into the forward fuselage section of the aircraft. Pictured below is a Spirit Wichita employee working on a lower lobe side panel.

Here are some interesting numbers: there are 179 KC-46 Tankers and about 50 other 767 aircraft in backlog. With a production rate of 2 frames per month, the 767 line will be open for the next 10 years.

I think the assembly is going to be the same as with all other 767s: First at vendors (what you see here) then in Washington. I thought Tinker is where they make it into an actual tanker (Boom, specialized equip, etc.).

Boeing agreed to close the Boeing-Wichita Modification Center and move the tanker modification work to the Puget Sound as part of their latest contract with the IAM.

Global Transport & Executive Systems is moving from Wichita to Tinker and Tinker is also handling the B-52 upgrades.

There are active campaigns to sell the KC-46A internationally, which I believe will happen as KC-46As are delivered to the Air Force. If this program is executed anywhere near as efficiently as the P-8 Poseidon program, follow on orders shouldn't be a problem at all.

Yes and no. The P-8 does not have a real competitor. The KC-46 does. And as been discussed previously, foreign air forces may have different requirements that may drive them to a larger A330.

I believe the KC-46A has a decent shot at securing foreign orders now that it's going to be in significant production thanks tot he USAF buy (especially if it's chosen to replace other USAF 707-based platforms).

Of the current KC-135 operators, France have already committed to the A330MRTT, but I think Turkey and Chile could be KC-46A customers (Turkey is a customer for the Boeing 737 AEW&C) and maybe even Singapore.

Israel is a pretty safe choice as well, I would think, to replace their 707 tankers with the KC-46.

Israel is getting KC-135Rs from the USAF. They won't need the KC-46A, at least for a while. 20 years down the road it may be something else if those IDF KC-135s need replacing.

Those countries that buy the F-35A and/or F-15SE may consider the KC-46 tanker. The ROKAF is making their choice now about buying either of these airplanes, but they are not needed for defensive or offensive against North Korea. They will need them against any aggression by Russia, China, or Japan. Since the F-35A has a combat radius of less than 600 nm, and the F-15SE a range of 800 nm, a tanker will be needed for these projection missions.

Boeing now has two KC-46 Booms in production, as seen in this video;

Have not heard much more about this. It is thought 3 KC-135Rs will go to the IDF, but it could be as many as 5-6. I don't know who would loose any KC-135s, but I am thinking these tankers will be transferred as they come out of the TIK depot, with Israeli roundels. They may also have Israeli specific modifications for some avionics, and possibly a defense system (which the KC-135s do not have now). Israel may also want receptacles installed to take on fuel from the IDF KC-707s.

I am just guessing at all of this. As you know, Israeli weapons systems capabilities are not made public.

I do not know when the IDF aircrews will enter type training at LTS, but my guess is about 6 months before the first KC-135 is delivered.

My guess is the costs will be covered by the US, as is most of the Israeli weapon systems.

Neither the first or second KC-46 have begun "final assembly". They have just begun assembly.

The first KC-46A will fly initially as a B-767-2C in 2014, where it will get initial FAA approval for the B-787 avionics, body fuel tanks, cargo floor and door, etc. It will later go back into the assembly building for conversion to full KC-46 configuration. The second KC-46 will complete the B-767-2C STC with the FAA wile #1 is rebuilt. It will begin flying as a KC-46A in 2015. There will be a total of 4 airplanes in the flight test program. KC-46A #5 or #6 will be the first new tankers delivered to the USAF in 2016, followed by the remaining 8 production tankers, followed by the 4 flight test tankers by late 2017.

All 18 of these tankers will initially be assigned to the 22nd Air Refueling Wing at McConnell AFB, KS and used for training and qualifications and IOC. The 157th Air Refueling Wing, NHANG, Pease ANGB, NH will be the first full deployable combat wing.

TopBoom, thanks for the explanation of the production sequence. Any idea what the first year of tail numbers will be? FY13?

Also wondering what the official Boeing civilian model designation will be... B767-2C? Or will it have a customer code stuck in there somewhere (such as B767-253C)? Does it get an ER/LR tag too, or is it like the 777F where that's implied?

I believe the 4 SDD tankers will all have 2014 tail numbers, even though they were funded back in 2012. This is because they will initially be civilian airplanes. The remaining 14 tankers will have 2015, 2016, and 2017 tail numbers.

Yes, as far as I know, the official civilian designation will be B-767-2C, with the customer code after that. So, using your example it would be a B-767-2C53 with maybe an "F", "ERF", or "LRF" stuck on the end. An airplane ordered by UPS could have the Boeing designation of B-767-2C4A, FedEx would be B-767-2CS2.

Boeing could also drop the customer codes altogether like they do for the B-787-8/-9 models.

Boeing's latest price list added a 767-2CFX so it stands to reason should a civilian order the type, it will be 767-2CF or 767-2CXXF (where XX is the customer code).

The military versions appear to be 767-2C as that is how the first four, at least, are identified on Boeing's O&D site. Once actual production frames enter the line, that might change to KC-46 or stay 767-2C.

If I understand your question correctly, the customer code that Boeing Commercial Airplane assigns to these KC-46 would be similar to the ones assigned to the P-8 which is designated to The Boeing Company. This is because the frame is delivered to Boeing Defense System which does the the Mission Installation before delivering to the Air Force.

The four C-32As (B-757-2G4ER) were all new builds for the USAF. The C-32Bs were bought as used aircraft. The C-32A has PW-2040 engines and the C-32B has RR RB-211 engines and an air refueling receptacle, which gives the "ER" capability.

Boeing has a different customer code for the USN and USAF. Boeing's own customer code is "20" and "T9", for the USAF it is "26" (VC-137A/B/C, some C/KC-135s, other KC-135s were "46", "48", and "66") "DM" (C-40B, the C-40Cs were all bought as used aircraft, at least two of them from Ford Motor Company, making them B-737-BBJ2CP), and "G4" (VC-25A, C-32A, the YAL-1A was a B-747-4G4F), for the USN/USMC it is "AF" (C-40A) and "FV" (P-8A).

The B-52 evolved from Boeing model B-462, B-464-29/-35/-49/-67, and B-52A as a unique military program.

A few milestones:

8/23 - 2nd frame begins assembly - http://boeing.mediaroom.com/Boeing-B...embling-2nd-KC-46A-Tanker-Aircraft

Quote:

Boeing [NYSE: BA] officially began assembling the second KC-46A Tanker this week as workers loaded the aircraft’s wing spar into an Automated Spar Assembly Tool.

...

The first test aircraft is expected to roll out of the factory in January 2014, while the second is scheduled to leave the factory in March. Boeing plans to fly the fully provisioned tanker for the first time in early 2015 and make the first delivery in 2016. The company expects to build and deliver the first 18 KC-46As by 2017 and a total of 179 by 2027 if all options under the contract are exercised.

“We’re exactly where we want to be right now,” said Maureen Dougherty, Boeing vice president and KC-46 Tanker program manager. “One year from now, all four test aircraft will be out of the factory, and the first two will be flying.”

9/6 - Final design frozen - http://boeing.mediaroom.com/US-Air-F...lize-KC-46A-Tanker-Aircraft-Design

Other articles point out that the key to keep the program on track is avoiding any add-ons beyond the initial specification.

I'm sure many can dream of an E-10 type aircraft in the future, but it's damn good to see this program not get burdened by any other requirements.

You might want to check out this discussion: Rivet Joints For RAF (by Devilfish Mar 22 2010 in Military Aviation & Space Flight)

To save you the time:

Quoting garysted (Reply 23):
Hopefully not complicating matters, but just to clarify what I said in the previous posts, but a very small number of USAF KC-135R's do have the boom receptacle fitted and are usually referred to as KC-135R/ARR's. I believe - and I'm sure some of the other posters could clarifiy - that it's only about 6/7 and they're all at McConnell. These were aircraft that were converted to other configurations and fitted for AAR, and were then converted back to the KC-135R standard. Again, I'm sure others have more detailed info.
Quoting KC135TopBoom (Reply 41):
Actually all KC-135s can receive fuel inflight. The process is called reverse refueling and is only accomplished in an emergency. The Boom Operator makes a contact with a large/heavy receiver (B-52, other C-135 type, E-3, C-5, etc.), the receiver pressurizes his refueling system and the Boom Operator holds the retract lever slightly in the retract position to open the fuel by-pass valve and fuel is pumped only into the aft body fuel tank. The 'on-load' depends on how much fuel is in the forward body fuel tank so the aft CG limit isn't exceeded. Before the refueling the Boom Operator must compute how much fuel to on-load into the aft body fuel tank before the refueling is accomplished. Once fuel begins showing in the aft body tank, the pilot can begin burning that new fuel.

I'm aware of the previous discussions you mentioned...a small number compared to the fleet and the statement they can receive fuel via boom is NOT a commonly accepted practice. The poster I quoted is making it seem like a normal thing they can 'just do' whenever the need hits. That is NOT the case. It's my bad for saying 'no, they can't'. I should have said it differently.

As I said in the Rivet Joint thread, it is an emergency procedure. It is an accepted practice, in fact how to do it is in the flight manual.

I was wondering if the KC46 fuse was indeed longer than 767-200

Based on that

and that

I find it's the same length
Wasn't it supposed to be 2 m longer than 767-200 ?

The 767-2C / KC-46A is 165 ft 6 in (50.5 m) and the 767-200 is 159 ft 2 in (48.5 m).

I don't see an overall length in the IAI Freighter document, so how is it generating a discrepancy?

The length of the KC-46A is for the fuselage only. It does not include the air refueling boom in the stowed position. The KC-46A is 6.5' longer than the KC-767A/J or the B-767-200ER. The extra length is why Boeing has a separate designation for the airframe, the B-767-2C.

No, the Boeing designation for the B-767-200 is a separate designation from the B-767-2. Boeing never build a B-767-200C. They only had the -200, -200ER and a converted freighter called the -200CF. The B-762s come with a MTOW of up to 395,000 lbs. The B-767-2C/KC-46A will have a MTOW of 415,000 lbs. The Boeing built KC-767A/Js for Italy and Japan have a MTOW of 395,000 lbs.

The first KC-46A will fly initially as a B-767-2C in 2014, where it will get initial FAA approval for the B-787 avionics, body fuel tanks, cargo floor and door, etc. It will later go back into the assembly building for conversion to full KC-46 configuration. The second KC-46 will complete the B-767-2C STC with the FAA wile #1 is rebuilt. It will begin flying as a KC-46A in 2015.

I'm obviously wrong, but I was under the impression that aircraft intended for military purposes didn't need FAA certification. Why is this necessary for the KC-46? Is the P-8 also FAA-certified? What about the B-52 and KC-135 and every other U.S. military aircraft?

Being FAA certified just saves the USAF from performing the certification themselves (saves money) as the system that Boeing uses to certify a commercial airplane should be really efficient.

For the P-8A, I believe the plane that flies from Renton to Boeing Field is FAA certified. I'm not sure if the ones that gets delivered with all the mission system is FAA certified. Don't know if the FAA would ever certify a weapons system or aerial refueling systems.

The B-52 and KC-135 never received an FAA Certification, they didn't need one. The first US Military aircraft to get an FAA Certification was the C-141A as Lockheed wanted to sell it as the L-300.

The second US Military airplane to receive an FAA Certification was the KC-10A.

The USAF wanted the certification to be able to use airline DC-10 parts around the world and vice-versa.

The A-330MRTT and A-400M also received a civilian certification.

But, you are correct, normally military aircraft do not need a civilian certification.

The certification needed for the KC-46 is not just for the tanker parts, but the B-767-2C is a new B-767 model and may have later civilian sales.

The wings are already strengthened to carry the WARPs, so they should accommodate winglets of whatever type are available then. Of course the USAF could add raked wingtips now and be done with it.

The Lexington Institute (Dr. Goure) has a piece explaining some production philosophy differences between different agencies like the DOT&E and AT&L. There is more info on the below link if your so inclined.


http://www.lexingtoninstitute.org/bo...with-p-8-and-kc-46a?a=1&c=1171

Quoting from the article:

"Before the DOT&E reports cause concerns, consider the views of the Pentagon’s chief acquisition official, Undersecretary for Acquisition, Technology and Logistics (AT&L) Frank Kendall, on the P-8. According to Kendall, the P-8 is a “good product” and represents a “relatively successful program.” Why the disconnect between DOT&E and AT&L? Apparently, DOT&E didn’t bother reading the program plan for the P-8. Kendall responded to the DOT&E report in recent testimony before the House Armed Services Committee saying “the capabilities that the DOT&E report talked about not being there are underway. They’re coming. We’re going to move onto wider-area surveillance capabilities I think within a few years. So the aircraft actually is, I think, a relatively successful program despite the tone of that report.”

The DOT&E organization was intended to be an advisor to the Secretary of Defense to ensure that programs were able to demonstrate operational effectiveness in realistic testing. In recent years its role has morphed from protecting the welfare of our warriors to a roadblock to their receiving important new capabilities. The disagreement between DOT&E and AT&L on the P-8 has been repeated with other programs, notably the F-35. In both cases, DOT&E apparently doesn’t take into account that virtually all major defense programs involve the phased introduction of capabilities. The same is true for software. The F-35 program always intended to operate initially with a software system that was less complete that the full up version. Frankly, without a degree of concurrency in development and production the military would have to wait until the “gold standard” version of a platform was developed and tested before it could begin production. The Government Accountability Office recently reported significant improvement in the F-35 program; DOT&E continues to carp. Apparently, DOT&E doesn’t understand how defense production programs work."

Interesting!

The article goes on to say:

Quote:

The Air Force will buy 179 KC-46A Pegasus aircraft, the last of which will be delivered in 2028, to replace the Eisenhower-era KC-135 fleet. However, USAF will continue to maintain 200-plus KC-135s, which will be 65-years-old or older when the last Pegasus is delivered. As a result, the KC-Y and KC-Z follow on efforts have to be real programs, said Welsh. “And they have to get going now,” he emphasized.

Good luck with that, Gen. Walsh. I know he's just toting the party line, but still, it's amazing to ask for more planes at the same time that you are talking about taking perfectly good KC-10s out of service.

I think this is just a start off order. There are currently 415 KC-135s in the USAF's inventory. To include the guard and reserve. The KC-46 will carry alot more cargo than the Kc-135 can, so I see higher utilization rates.

Except the Air Force isn't like a commercial carrier so utilization will remain "as required" which may be no more than today or even less.

Right, but the esteemed General is talking about adding two new systems, KC-Y and KC-Z, while other parts of his organization are grumbling they can't support the number of different systems they now have and in particular are talking about prematurely ending the life of KC-10 amongst others. Although most of us feel that it'll be KC-46 or nothing, the General seems to need to keep pushing the party line of three separate tanker replacement programs.

Evidently by "start" they mean they are doing build-up of sub-assemblies. The wings, tail and wing-body join are done in Building 40-33, adjacent to the FAL in 40-32.

So it sounds like #1 and #2 are in the two FAL positions right now and #3 and #4 are being built-up.

Those are Pilot Director Lights - they help guide the receiver pilot while connected to the boom. The KC-135 and KC-10 have them as well.

There are no current plans for blended winglets for the KC-46A. But later versions could have them, or even raked wingtips.

There may be some issues with interference with onboard sensors or wake vortex issues with receiving aircraft or trailing aircraft waiting to hook-up.

If they do add winglets, I would guess they would go with raked wingtips (ala the 767-400ER and P-8) as those seem to be better for longer missions.

A lot of that depends on the speed and altitude of the missions. I never have seen a typical mission profile for these. But, if they spend most of the patrol low and slow, raked might not do much good.

Yes. The straight forward answer is:

Quote:

“Based on the USAF refueling requirements, the missions were not of sufficient duration nor conducted at altitudes that optimize the benefits derived from winglets,” Boeing told Aviation Week.

Ref: http://blog.seattlepi.com/aerospace/...-wont-have-winglets-aviation-week/

Keep in mind Boeing was under extreme pressure to keep the price low, as IMHO they should be, and thus "optimize" means optimize with respect to price/performance not just absolute performance.

Well, the P-8A mission is often low and slow looking for submarines. Tankers, OTOH spend most of their time high and fast. There are exceptions for both the P-8 and the KC-46. But raked wingtips would be better, and provide a better reduction in drag than blended winglets/sharklets do.

Boeing currently has raked wingtips on all B-748s, B-764s, B-77F/L/Ws, as well as the P-8.

This falls into the "missions were not of sufficient duration" clause of #96 above.

Sure, the winglets will save fuel, but these a/c do not fly anywhere near as much as do commercial a/c so the fuel savings is not as great. The winglets add cost, weight and maintenance issues. They only pay for themselves if the plane spends lots of time at cruise altitudes. The tankers just won't fly enough hours at cruise altitudes to save enough fuel to pay off the winglets. The competition (Mk.III) made it clear that the low cost bird would win the competition, and so, no winglets!

Sorry, but it's not a commercial product with just a long, hard appendage attached to the bottom of the stern. Many major components, including the cockpit itself, are completely different than the commercial product and are spec'd to DOD requirements.

The cockpit structure is still commercial. Most of the systems that fly the airplane are still commercial. There may be some systems that are specifically military like the secure com link and ewsp system.

But being commercial is more than just the hardware. It's the complete manufacturing process from ordering materials to the final bolts. Boeing is taking advantage of the existing commercial infrastructure to reduce the cost of the tanker. If you can share the overhead with the other programs, you can save significant money. (Enven thoughn Boeing's overhead is pretty high).

Their bid was a tad optimistic. But it's not all overrun. They're spending a billion more than scheduled for development, but the program chiefs say a lot of that is work and risk retirement that was originally planned for later, and everything is pretty much on budget, so they'll recoup some of it in the future under production expenses.
The Air Force's claim of development cost overrun doesn't agree with Boeing's claims. Boeing says it's more a case of shifting productions costs to development, and is just an accounting change. It's very common to do stuff like that to move profits and losses from one budget to another depending on corporate profit and tax situations for those years.
It's like Boeing taking billions in losses for 787 development to get certain expenses out of the production budget.
(A guess on my part. Stitch probably knows a lot more about that situation)

What are Boeing's projections for the USAF past their initial 179 plane order? Im very skeptical that it would be a 1:1 replacement for the KC-135s. Either way 179 is a far cry from the current force strength of of 415 KC 135s.

"WASHINGTON — The projected price tag for the new Boeing KC-46 tanker has fallen $1.8 million per aircraft, according to a new Government Accountability Office (GAO) report.

The US Air Force program “has made good progress over the past year” as “acquisition costs have remained relatively stable” and “the program is on track to meet performance parameters,” GAO said in the report released on Thursday.

“The next 12 months will be challenging as the program must complete software development, verify that the software works as intended, finalize developmental flight test planning and begin developmental flight tests,” the report states.

The estimated price tag for the entire program has also fallen $323 million to just under $51.4 billion, according to the report.

That would be my guess also. The body tanks are bladder tanks that need servicing every now and then. The access panes on the bottom of the KC-135 to the body tanks is a very small panel, just large enough for a man to fit through. The bladder tank segments are installed and removed through this panel, and the maintenance guys say that is a real pain in the butt.
The air refueling fuel pumps, in the body tanks are also serviced though the bottom of the KC-135, they are large, heavy, and cumbersome to fit through the panels too.

Leaving the fore and aft cargo doors reduces structural design changes and improves maintenance access. I do notice there is no bulk cargo door aft of the aft cargo door.

Quoting KC135TopBoom (Reply 130):
That would be my guess also. The body tanks are bladder tanks that need servicing every now and then. The access panes on the bottom of the KC-135 to the body tanks is a very small panel, just large enough for a man to fit through. The bladder tank segments are installed and removed through this panel, and the maintenance guys say that is a real pain in the butt.
The air refueling fuel pumps, in the body tanks are also serviced though the bottom of the KC-135, they are large, heavy, and cumbersome to fit through the panels too.

Leaving the fore and aft cargo doors reduces structural design changes and improves maintenance access. I do notice there is no bulk cargo door aft of the aft cargo door.

Thanks for the info TBoom, best wishes.

Anyone know if the auxiliary fuel tanks are installed already on the production line or do these mods come later ?

For P-8A they had the tanks in first. Then they have to take 'em out for the mission installation phase.

From a manufacturing stand point, it doesn't make sense. But then you have to figure on how the plane was certified.

It may have been easier/cheaper to certify the tanks as part of the basic frame configuration (before the "mod") than trying to do it after.

For the P-8A the tank configuration was probably already certified by the BBJ.

For the tanker, it would depend on if they already have a certified configuration. Otherwise from manufacturing stand point, it would be better to have the tanks in during the mission system installation phase.

I would guess cargo hold fuel tanks would not be standard equipment, or perhaps even on option, on the civilian 767-2C cargo airframe, so that could mean that they would not be part of the basic airframe certification and would be added during the mission system installation phase.

The aux tanks will be certified during the 767-2C amended type certification and conseq. must be installed at the assembly line.

See the speech of Major General John Thompson AFA held at the Air and Space Technology Exposition, with the titel " KC-46 Requirements " at 17 September 2013 :
http://www.af.mil/Portals/1/document...0events/af-130917-AFA-Thompson.pdf
And look at page 5.

"Then as the aircraft proceeds down the line in the plant there at Everett we are turning out a provision freighter which we refer to as the 767-2C.
That's our baseline aircraft that will come out of the end of the factory. It will have the enhanced flight deck, it will have the cargo floor and door, it will have the body fuel tanks for the air refueling mission and lots of provisions for the tanker system "

I suspect the absence of wing tips on roll out is related to the plane exiting the rear of the FAL and being towed down a narrow alley.. we may or may not ever see them installed in the FAL, but that's why the EMC is important.

Or . . . the wing tip contains mission system gear that gets installed at the Military Flight Center.

The only comparable thing I can think is the 737 AEW&C EWSP sensors (I think) out on the wind tip.

Why have two different procurement programs to replace one aircraft?

Because there are so many KC-135s being replaced.

Also I believe we can presume it is two types of aircraft: KC-135E and KC-135R, because they have different maintenance profiles.

I'm wondering if similar tanks were used by KC-767 for Japan and Italy.

The KC-767A and J models do not have body fuel tanks. They carry a lot less fuel than the KC-46 will carry, and both have a lower MTOW. The KC-767A/J carry a max fuel load of 160,000 lbs., all in the original fuel system of the B-767-200ER with a center wing fuel tank. The KC-46A will carry about 215,000 lbs. of fuel.

The KC-767A/J have a MTOW of 395,000 lbs., the KC-46A will have a MTOW of 415,000 lbs. Yes, the difference is about 50,000 lbs. in fuel, but only 20,000 lbs. in MTOW. Remember the KC-46 will not have an airliner interior with pax seats, like the Italian and Japanese models do (although it is a quick change interior for Japan). There are other features the Italians and Japanese have that are not in the US version, or are different features.

That's a lot of fuel in a very compact and agile Aircraft, in my opinion I don't think you could have found a better airframe for the job. Even the -400 version still 'only' carries 160k of fuel yet its enough to go NYC-HNL non stop, up to 12 hours sometimes in the winter in a much heavier (450k) aircraft.


215 thousand pounds of fuel in that -200 airframe is a lot of bang for the buck and it will have a lot to give away, it will also take up very little space on the ramp, have a great cargo and / or passenger capacity and be able to maneuver in flight without hard limits. I would think this could be a great advantage to the Air Force.



This was a very good choice despite the delays it took to make the decision and I hope they buy a lot more. It seems like an ideal aircraft to replace the rest of the KC135's and the AWAC'S / JSTAR fleet.
