Developing something that big and complex could never be done in secret these days or in the 90s.
It is perhaps worth mentioning that while the airframes were smaller than something XB-70 sized, OXCART, Have Blue, Bird Of Prey, Tacit Blue, Senior Trend, various MiG's, various helos, some very large and complex space based sensors, and now a 6th gen fighter jet were all flown in secrecy by the USA and some of these were large and complex programs. OXCART was over 100,000 pounds, quite complex and 15 were built. Not a small program.
