The Hunt for Red October - Tom Clancy [31]
"I'm sure the thought occurred to them," Greer observed. "It would have occurred to us. Well, we have Bremerton up there to keep an eye on her, and if this data turns out to be useful we'll see if we can come up with an answer. How are you feeling?"
"I've been on the go since five-thirty London time. Long day, sir."
"I expect so. Okay, we'll go over the Afghanistan business tomorrow morning. Get some sleep, son."
"Aye, aye, sir." Ryan got his coat. "Good night."
It was a fifteen-minute drive to the Marriott. Ryan made the mistake of turning the TV on to the beginning of Monday Night Football. Cincinnati was playing San Francisco, the two best quarterbacks in the league pitted against one another. Football was something he missed living in England , and he managed to stay awake nearly three hours before fading out with the television on.
SOSUS Control
Except for the fact that everyone was in uniform, a visitor might easily have mistaken the room for a NASA control center. There were six wide rows of consoles, each with its own TV screen and typewriter keyboard supplemented by lighted plastic buttons, dials, headphone jacks, and analog and digital controls. Senior Chief Oceanographic Technician Deke Franklin was seated at console fifteen.
The room was SOSUS (sonar surveillance system) Atlantic Control. It was in a fairly nondescript building, uninspired government layer cake, with windowless concrete walls, a large air-conditioning system on a flat roof, and an acronym-coded blue sign on a well-tended but now yellowed lawn. There were armed marines inconspicuously on guard inside the three entrances. In the basement were a pair of Cray-2 supercomputers tended by twenty acolytes, and behind the building was a trio of satellite ground stations, all up- and down-links. The men at the consoles and the computers were linked electronically by satellite and landline to the SOSUS system.
Throughout the oceans of the world, and especially astride the passages that Soviet submarines had to cross to reach the open sea, the United States and other NATO countries had deployed gangs of highly sensitive sonar receptors. The hundreds of SOSUS sensors received and forwarded an unimaginably vast amount of information, and to help the system operators classify and analyze it a whole new family of computers had to be designed, the supercomputers. SOSUS served its purpose admirably well. Very little could cross a barrier without being detected. Even the ultraquiet American and British attack submarines were generally picked up. The sensors, lying on the bottom of the sea, were periodically updated; many now had their own signal processors to presort the data they forwarded, lightening the load on the central computers and enabling more rapid and accurate classification of targets.
Chief Franklin's console received data from a string of sensors planted off the coast of Iceland . He was responsible for an area forty nautical miles across, and his sector overlapped the ones east and west so that, theoretically, three operators were constantly monitoring any segment of the barrier. If he got a contact, he would first notify his brother operators, then type a contact report into his computer terminal, which would in turn be displayed on the master control board in the control room at the back of the floor. The senior duty officer had the frequently exercised authority to prosecute a contact with a wide range of assets, from surface ships to antisubmarine aircraft. Two world wars had taught American and British officers
