"Agreed," Perrin answered. "Our last datum point was within one thousand yards of your position. We have nothing at this time."
O'Malley examined the data transmitted from Battleaxe's plot. As was usually true of submarine course tracks, it was a collection of vague opinions, shaky judgments, and not a few wild guesses.
"Bravo, you're a sub-driver. Talk to me, over." This was lousy radio procedure, but what the hell?
"Hammer, the only thing that makes the least bit of sense is that he's extremely fast." O'Malley examined the tactical display more closely.
"You're right, Bravo." O'Malley pondered this. A Papa, maybe? he wondered. Twin screws, cruise missiles, fast as a thief.
"Hammer, Bravo, if we proceed on the assumption that he's very fast, I recommend you go east until Romeo comes off sprint and can give us a bearing."
"Concur, Bravo. Give me a vector." On command from Battleaxe, the Seahawk ran twenty miles east and began dipping his sonar. It took fifteen minutes to load another pair of Stingray torpedoes on Hatchet, along with fuel and sonobuoys.
"What do you think we're after, skipper?" Ralston asked.
"How's a Papa grab you?" O'Malley asked.
"But the Russians only have one of those," the copilot objected.
"Doesn't mean they're saving it for a museum, mister."
"Nothing, sir," Willy reported.
Reuben James came off sprint, turning to a southerly heading to bring her sonar to bear on the remaining contact. If only Battleaxe still had her tail, Morris thought, we could triangulate on every contact, and with two helos...
"Contact, evaluate as possible submarine, bearing zero-eight-one, bearing-changing slowly, looks like. Yeah, bearing changing north to south." The data went at once to Battleaxe and the screen commander. Another helicopter joined the hunt.
"Down dome!" This was the thirty-seventh time today, O'Malley thought. "My ass is asleep."
"Wish mine was." Ralston laughed without much humor. Again they detected nothing.
"How can something be exciting and boring at the same time?" the ensign asked, unconsciously echoing the Tomcat pilot days ago.
"Up dome! You know, I've wondered that a few times myself." O'Malley keyed his radio. "Bravo, Hammer, I got an idea for you."
"We're listening, Hammer."
"You have Hatchet dropping a line of buoys south of us. Deploy another line west. Then I start pinging. Maybe we can flush the guy into doing something. You ever get herded by a dipping helo when you were driving subs?"
"Not herded, Hammer, but I have gone far out of my way to avoid one. Stand by while I get things organized."
"You know, this one's a nervy bastard. He's gotta know we're onto him, but he isn't breaking off. He really thinks he can beat us."
"He has for the last four hours, boss," Willy observed.
"You know what the most important part of gambling is? You have to know when it's time to quit." O'Malley circled up high and turned his search radar on for the first time that day. It was not very useful for detecting a periscope, but it might just scare a sub running near the surface into heading back under the layer. The sun was sinking, and O'Malley could pick out the two other helicopters working this contact from their flying lights. They dropped two lines of passive sonobuoys, each eight miles long, at right angles to each other.
"The picket lines are in place, Hammer," Captain Perrin called. "Begin."
"Willy: hammer!" Six hundred feet below the helicopter, the sonar transducer pounded the water with high-frequency sonar pulses. He did this for one minute, then reeled in and flew southeast. The process lasted half an hour. By this time his legs were knotting up, making his control movements awkward.
"Take over for a few minutes." O'Malley took his feet off the pedals and worked his legs around to restore circulation.
"Hammer, Bravo, we have a contact. Buoy six, line Echo." This was the east-west line. Buoy number six was third from the west end, where the north-south "November" line began. "Weak signal at this time."
O'Malley took the controls back and headed west while the other two helicopters circled behind their respective lines.
"Gently, gently," he murmured over the intercom. "Let's not spook him too much." He picked his course carefully, never heading directly for the contact, never heading far away from it. Another half hour passed, one miserable second at a time. Finally they had the contact running east at about ten knots, far below the layer.
"We now have him on three buoys," Perrin reported. "Hatchet is moving into position."
O'Malley watched the blinking red lights about three miles away. Hatchet dropped a pair of directional DIFAR buoys and waited. The display came up on O'Malley's scope. The contact passed right between the DIFARS.
"Torpedo away!" Hatchet called. The black-painted Stingray dropped invisibly into the water, half a mile in front of the oncoming submarine. O'Malley closed and dropped his own buoy to listen as he brought the Seahawk into hover.
