Another possible Northrop design, whose mission would be as a low-observable recon platform. Derived from the THAP (Tactical High Altitude Penetrator) studies. Current thinking suggests it has the ability to collect and transmit digital photo information back to F-117s. Able to operate at high and low altitudes, with a range in the region of 5,000 km. Possibly carries 1 Paveway II LGB in an internal bay.

Has been reported flying with KC-135 tankers, F-117s and T-38s. Said to use GE F-404 engines, and is quieter than the F-117. Reported to be operational with F-117s during the Gulf War, operating as "Team Stealth" - a term used on flight patches on F-117 pilots. Observer reports indicate that the TR-3 may have a more triangular planform with rounded tips, but there are also reports of a craft with more sawteeth across the trailing edge. This has been called "Artichoke", and may indicate follow-up work on F-117, possibly a larger, more capable aircraft.

Both versions - sawtooth and rounded - are represented here. Indications are that significant further information about this aircraft will appear over the next month or two.
