NT-43A (Rat 55)

The NT-43A also known as the Rat 55 is a highly modified 737-200 owned by the USAF that is more secret than your average USAF aircraft. No one knows where the aircraft is kept and no one knows what’s inside but it has been reported that the technology inside is much better than your average spy/radar plane. The aircraft was built and designed by multiple companies including Lockheed’s Skunk Works and Goodyear Aerospace. According to Globalsecurity.com, the NT-43A’s genesis may have deep roots dating back to the origins of stealth technology.

This would be a very cool and interesting aircraft to see in infinite flight and would definitely be a favourite towards those “Airforce Nerds”

Flying hotdog? I wanna fly it 😂


Well I think that’s our first promblem here. We cant get any details on how the aircraft performs as an aircraft leaving us unable to put it in IF.


there are ways to find this stuff out. I only read one article and im in thr process of reading another one

That’s Awesome. Usally the USAF never like to release info. But maybe because it’s a commercial jet they did it for that reason

The performance of these types of aircraft isn’t considered secret, the secret part is their functionality and equipment, along with the obvious cryptographic material and produce.

You’d be surprised at how open the USAF and other militaries are about the actual airframes performance on such aircraft.

I have just added the specs
