Lockheed developed ways to bend, stamp, and drill/machine titanium sheet and plate for the A-12/SR-71. The Boeing stuff are heavy titanium forgings, very very different and Boeing had a Russian industrial partner, AVISMA, for their titanium parts. To this day AVISMA remains the worlds #1 producer of raw titanium and titanium parts which they sell worldwide, including to Airbus, Boeing, Lockheed, NASA, etc, etc.
