Jumpseat and Trumpet Hidden ELINT Architecture
JUMPSEAT mattered because it solved a geographic problem. The most important radar and weapons targets were concentrated in the far north, where geostationary satellites were poorly placed and low-orbit satellites moved too quickly. Highly elliptical orbit changed that. It let an American signals-collection satellite linger over the northern hemisphere long enough to turn fleeting collection into a more durable listening architecture. TRUMPET inherited that logic, and the result was one of the least understood but most persistent branches of U.S. overhead intelligence.
