America’s “stealth revolution” took place in the mid 1970’s, spawned by advances in computer processing and aircraft manufacturing techniques, as well as the ongoing Cold War.By the turn of decade multiple “low observable” programs, spearheaded by a variety of manufacturers, were well underway.The aircraft had to feature “all aspect stealth,” whereas an aircraft like the F-117 could be optimized for front and rear, or “coming and going” stealth aspects, as their mission was sneak inside a defense network, drop bombs, and high tail it out of danger.Tacit Blue had no such luxury as it would have to loiter for hours over enemy territory, and thus every angle would be susceptible to radar surveillance for prolonged periods of time.Further, how would they ensure that the radar itself was not detected through its high power emissions?
The concept behind such emerging capabilities was to use a large phased array radar, mounted on an airplane, to provide real-time Ground Moving Target Indicator (GMTI) intelligence.New singles are joining all the time and making connections every day.

My first piece on the ancestry of the RQ-170 Sentinel, America’s secret unmanned stealthy sensor truck of choice, got a lot of traffic and was the topic of one of my recent colorful interviews on John Batchelor’s national radio program (At the time, aerial intelligence was collected via fighter jets, or other very un-stealthy aircraft, that were fitted with cameras and sent out to make daring runs, sometimes at very low-level and at very high speeds, over enemy territory.At best these systems could capture a snapshot in time of the enemies force posture, which could never be exploited in real-time, and was only gained at incredible risk to the aircrews involved.
