"It will anger my brother, but it must be lonely down there." Again Sato switched his radio setting, then depressed the switch on the wheel. "JAL 747 Flight calling Mutsu."

Admiral Sato wanted to grumble, but it was a friendly voice. He took the headset from the junior communications officer and closed his thumb on the switch. "Torajiro, if you were an enemy I would have you now."

He checked the radar display-only commercial targets were on the two-meter-square tactical-display screen. The SPY-1D radar showed everything within a hundred-plus miles, and most things out to nearly three hundred. The ship's SH-60J helicopter had just refueled for another antisub sweep, and though he was still at sea in time of war, he could allow himself a joke with his brother, flying up there in the big aluminum tub, doubtless filled with his countrymen.

"Time, sir," Shaw said, checking his electronic stopwatch. Commander Claggett nodded.

"Weps, bring them up and go active."

The proper command went to the torpedoes, now nearly two miles apart on either side of the target. The ADCAP-"additional capability"-version of the Mark 48 had a huge solid-state sonar system built into its twenty-one-inch nose. The unit launched from tube one was slightly closer, and its advanced imaging system acquired the destroyer's hull on the second sweep. Immediately, the torpedo turned right to home in, relaying its display to the launch point as it did so.

"Hydrophone effects, bearing two-three-zero! Enemy torpedo hearing three-zero!" a sonar officer shouted. "Its seeker is active!"

Sato's head turned sharply toward the sonar room, and instantly a new item appeared on the tactical display. Damn, he thought, and Kurushio said the area was safe. The SSK was only a few miles oil.

"Countermeasures!" Mutsu's captain ordered at OIKC. In seconds the destroyer streamed an American-designed Nixie decoy off her fantail.

"Launch the helicopter at once!"

"Brother, I am somewhat busy now. Have a good flight. Good-bye for now." The radio circuit went dead.

Captain Sato first wrote off the end of the conversation to the fact that his brother did have duties to perform, then before his eyes he saw the destroyer five miles below him turn sharply to the left, with more boiling foam at her stern to indicate a sudden increase in speed.

"Something's wrong here," he breathed over the intercom.

"We got him, sir. One or both," the fire-controlman announced.

"Target is increasing speed and turning to starboard," sonar reported.

"Both units are in acquisition and closing. Target isn't pinging anything yet."
