Now available are scans of two large and detailed diagrams of the Northrop YF-23 stealth fighter. Included:

1) Drawing 400L005002, sheet 1 of 2: provides top, bottom, left and right inboard views, with scrap inboard views through the engine and upper avionics bay. An impressive 27,000 by 7032 pixels, black & white. Original scan was missing much of the title block, but the rest of the image is intact.

2) Drawing 400L005002, sheet 2 of 2: provides 21 cross-sections of the YF-23. Smaller than sheet one, it’s still a large 17,696 by 6,944 pixels, black and white.

Also included are grayscale half- and quarter-size versions for easier viewing and printing. Together these would make a very useful resource for model builders… either to perfect a kit, or to scratchbuilt a large-scale display or even RC flying model.

Air Drawing 47 can be downloaded for $3.

  • Pete Murrie

    I LOVE your “airdocs”, all that how-it-works detail and pretty with it!

    Thank you again Scott!

  • Kelly Starks

    If I pay this project How do You intend to send me?


    Aug 27 2015 Today I ordered Air Drawing 47 , & paid with my paypal account which completed correctlly, ( transaction id ; 6pe20350k1575605j ) but now how do I get my drawings ?

    Is there a possibility to get the drawings printed and shipped to stateside addresses? If so, what would be the cost. Thanks. Rick

  • Is this still available?

    • Scottlowther
      • Excellent – I’ll head over later tonight. I just love the YF-23. Imagine if it had been chosen and it’s final state like the F-22? One can hope that this design will live on in the next phase of our sixth gen.

        • Scottlowther

          I wouldn’t bet on that. Lockheed is just about the only source for future fighters for the USAF… Boeing is no longer in the fighter business, NorGrumm is probably locked in with just bombers. There’s nobody else left, unless one of the smaller contractors – General Atomics, say – produces a small unmanned fighter.

      • Just ordered the YF-23 schematics. BTW, I’m considering creating an interactive book on Stealth Fighters and Technology to help educate more people of what it is and what it is not – do it in a visual and unique way that helps lay-people to get into the tech rather listen to hear-say media articles. Ideas on that thought?

      • Downloaded the files – thank you. Very nice and will review them in detail. I am wanting to print and frame one – would you happen to have a vector-based version in PDF so that my print quality can be much higher?

        • Scottlowther

          Nope. You got what came to me… a scan of a print. Defense contractors tend to be pretty twitchy about letting actual CAD drawings out into the world.

          Closest I’ve got are the CAD diagrams I drew myself from these, included in Aerospace Projects Review issue V3N2:

          • Well, I’ll see what I can get at the GIF level as to a hires print. Thanks for the response.
