How the hell is the US Navy equivalent to a privateer system? A privateer is a hired merchant vessel outfitted to be a ship of war. Every ship the US Navy uses is specially designed for war, with no other purpose possible. We do not camoflauge oureselves as merchant vessels to make a surprise attack on the enemy or to slip under their radar, we don't have to! We just blow them out of the water, fair and square.
And I think you misunderstand the idea of sattelite tracking. Sattelites can do several things, but none of them at the same time.
You can take pictures of an area, but it is only in the certain path that the sattelite follows above the Earth's surface. Geosynchronous sattelites are not used for warfare or spying, they are communications sattelites. Spy satellites orbit the earth, and follow set paths that take them over certain areas, such as part of Russia or Cuba. You cannot simply decide down here to change the orbit of a sattelite by firing some boosters that do not exist, you have to go up there and move the sucker with the Space Shuttle. Also, you cannot watch live feed from sattelites, thats why we have to take pictures with them. Sattelites are of no danger to the modern Navy in any way. They cannot see your position or track it, unles you are operating in that narrow band over which they orbit.
