A satellite jamming system seems almost timid compared to one of the original purposes of the Space Shuttle.
NASA wanted a much smaller and more agile orbiter. Because the shuttle was a joing NASA/DOD project, the military pushed for the much larger, less agile current design. The military wanted the ability to launch a shuttle into polar orbit from Vandenberg AFB in California, steal a satellite and return to Earth in a one orbit flight, returning to the launch site at Vandenberg within 90-minutes. The Russians would not even know the satellite was missing until they tried to contact it on the next orbit. This would have been used only during periods of national crisis and only against those Russian satellites considered a threat to our national security.
During those years the Russians had developed spy satellites similar to ours - essentially telescopes that looked down instead of up - small versions of the Hubble telescope, if you will. The size and mass of these satellites was known, so that dictated the minimum size of the shuttle's payload bay and the weight that the shuttle would be required to carry back to Earth for a landing. The requirement to land within one orbit of launch required that the shuttle have its familiar large delta wing instead of the thinner, smaller fighter-plane wing favored by NASA. The Earth would have rotated 1100 miles during the 90-minute flight, so the large wing would provide the ability to glide 1100 miles east during re-entry.
Temporarily jamming a satellite's electronics seems polite compared to our earlier aims. It must be part of a more sensitive military posture, I suppose. Just stealing the satellite outright sounds so crude today - such a nineties idea.
