Aerospace / Re: Boeing getting out of the fighter Business?
« Last post by marauder2048 on Today at 10:41:28 pm »
If you want to maintain design and manufacturing expertise useful for future fighter development perhaps the F-22 line was more important to preserve
than a line assembling a 90's era rehash of a 70's era design.

It's not the line, but the people from it that you need to maintain.

That, along with the developers, suppliers, maintainers, etc.

If they had continued producing the F-22 for the sake of keeping the line open, they would be stuck with 80's tech for the most part.  However, LM did not have to lose anything since they were able to transfer many of the developers, workforce, etc to the F-35 line, which for all intents and purposes is a higher technology and more efficient plane & production line.

With LM's experience now with two different 5th gen fighters, they are in a VERY good position going forward. 

Maybe Boeing just read the writing on the wall.

Of course, you are completely correct; people are the most important part. But part of recruiting and retaining top talent is keeping them interested and engaged on designing and developing the latest and (hopefully) greatest.  To Boeing's credit they spend more on defense IRAD than their peers and to LowObservable's point there are nearer term prospects that will satisfy the recruitment and retention issues I mentioned.

Ok, I've cleaned up this thread from attempts to restart the F-35 debate here again.
Please, stop yourself from getting into that discussion again ! Pretty sure, Boeings
fighter business can be discussed without any need to quarrel about the RCS of other
types !

Thanks airplane176.
A lot of time passed since my original post in May 2011 and since then I have found similar information.
Indeed they were supplied to Indonesia as TS-1A and S-2A whilst the USAF Academy operated some without designations but with serials 57-2769, 57-2770 and 57-2771 for the 2-22 (equivalent to the TS-1A) and 57-2768 for the 1-26 (equivalent to S-2A). A photo of the latter is enclosed.

I did find aircraft record cards for US Navy A-001/3599 on http://www.history.navy.mil/a-record/ac-hist-card/a51-a9206/a52-9206%20listing.htm This was some years ago so it might not be there anymore. The pdf files are, as memaerobilia stated, too large to post.

Early Aircraft Projects / Re: Manshu Ki-65 heavy fighter
« Last post by blackkite on Today at 08:27:18 pm »
Nario Ando, who was the manager of the No.1 department No.2 sectiom of the Aviation technology research institute of the IJA, took charge of the plan of many army warplanes.
Nario Ando has distinguished ki-65 from the heavy fighter No.1 planA and No.1 planB clearly in the “plan tale of the Japanese army plane” which is his work.
The proposal which sets the modified type of Raiden of the IJN to Ki-65 was given up because of development delay of Raiden.
Then, development of ki-65 was furthered by the Manshu airplane special group, which was prepared in the Aviation technology research institute of the IJA.
Possibly the extended engine shaft which was cause of development delay of Raiden was not adopted to Ki-65 at the time.
Because it was premised on adoption of Ha 211 engine(Mitsubishi MK9 engine) to Ki-65 whose diameter was small and more powerful compared with Raiden's Kasei engine.
Possibly Ki-65 was the very usual form as the downsized version of Reppu fighter which adopted the same engine.
Nario Ando stated in his book that the heavy fighter No.1 plan A was promising. Also he stated in his book that possibly it was better to further development of the heavy fighter No.1 plan A rather than Ki-93 attack aircraft. Perhaps it was the reason why Ki-98 selected mid engine.
Nario Ando did not stated that Ki-65 had unusual form in his work.

Diameter of Kasei engine : 1340mm, Diameter of HA211(MK9/HA43) engine : 1230mm

Blackkite,

Thanks for looking. Here are my english sources for the Ki-63:

http://en.wikipedia.org/wiki/Nakajima_Ki-62  (mentions the Ki-63 as a variant)

http://www.daveswarbirds.com/Nippon/aircraft/Ki-62.htm (same mention as a variant)

http://www.historyofwar.org/articles/weapons_nakajima_ki-63.html

All of these mention the Ha-102 as the engine for the Ki-63. This could be a case of one website repeating what another says.

I also found a Russian site that says the same thing. Here is the link to Translate it into english:

Early Aircraft Projects / Re: Nakajima Ki-62 light fighter
« Last post by blackkite on Today at 06:44:20 pm »

Nakajima ki-62 was a light single seat fighter plane following performance gain type ki-43Ⅱ which was planned by the "line of investigation" which the Japanese army formulated in 1940 and which made the battle for fighter plane the main purpose.
As the demanded performance,
(1)  Excellent dog fight performance.
(2)  High speed.
(3)  Combat radius  : 300 km~500 km+1 hour
(4)  Armaments :fixed machine gun 2(light-armed)
According to "the research schedule on the kind of next airplane" created by the Japanese army in June, 1940
(1)  The target date of No. 1 completion of ki-62 light fighter : February , 1941
(2)  The target date of the completion of examination of ki-62 light fighter : March, 1942.
However, the Aviation technology research institute of the IJA recommended that
(1) Ki-62 should install air cooling HA45 engine
(2) The target date of No. 1 completion of ki-62 light fighter should be changed in spring of 1942 and the target date of the completion of examination of ki-62 light fighter should be changed in middle of 1943.
