You're asking about coverage that we can provide. From Alert, we're doing signals intelligence rather than actual radars. The radars are the responsibility of the air force. For signals intelligence, once you send a message, it travels freely through the ether, right? So we're trying to intercept signals that may be even beyond our national borders.
We're looking at foreign signals intelligence that are well beyond the range of where our radar could actually see, given that the earth is curved and our radars go in straight lines from the ground. We're looking at covering and getting warning even before the radars can see things, if possible.
