“Skipper, I understand your desire to prevent bloodshed, but what can we do without revealing our presence?” pleaded Thigpen.

“That’s what I’m trying to figure out, Bernie!” snapped Jerry. He stopped and took several deep breaths. His XO wasn’t the enemy and Thigpen was only doing his job—perhaps, annoyingly, a little too well at the moment. His mind refocused, Jerry reapproached the problem.

“Okay. Active sonar is out. It’s a big neon sign that says ‘shoot here.’ The UUV is too far away, so we can’t use it as a diversion. And the mobile decoys are tuned for acoustic homing torpedoes.” Jerry ticked off the options on his fingers one at a time.

“And we can’t use any of our ADCs, as their electronic noise would be easily ID’d as American,” added Thigpen.

It was Thigpen’s last words that suddenly gave Jerry an idea. One that just might work. “Weps, we still have a few of those old NAE Mark 3 beacons on board, don’t we?”

“Yes, sir. We use them during exercises. They’re a lot cheaper than an ADC Mark 4.”

“Captain… what are you thinking?” Thigpen asked suspiciously.

“It’s quite simple, XO.” Jerry looked around for a piece of paper to draw on. Then remembered that there weren’t any paper plots—there wasn’t any room for them with all the electronic displays in a Virginia-class sub’s control room. Grabbing a pen from his pocket, he pointed to the geoplot display on the command workstation.

“We pull in behind the Kilo, overtake him, and drop an NAE with a time delay between the two boats. We then pull off to the north before either party has a chance to figure out what the hell happened.”

“But, sir, we’ll give ourselves away if we drop a countermeasure. They’ll detect it and know we’re here. There is no way to avoid that!” insisted Thigpen.

“You’re right, they’ll detect the NAE—but they won’t know it’s us. They won’t suspect it’s from an American sub!” Jerry exclaimed.

Thigpen was confused, frustrated, and it showed. “Huh? Come again? I’m not following you, Skipper.”

“Okay, look. The NAE is a very old countermeasure; the first models were designed in World War Two, over seventy years ago. It generates noise mechanically, not electronically. Neither the Vietnamese nor the Chinese would suspect the U.S. still has, or would even use, such a low-tech device.

“Also, when I was reviewing the log entries from Michigan’s engagement with the Iranian Kilo, my skipper, Kyle Guthrie, noted that the countermeasures deployed by the Iranian boat sounded almost exactly like an NAE. Don’t you get it? Both sides have Russian gear, including acoustic countermeasures! Each captain will think the other guy detected him and shot out a decoy! They’ll both be spooked and start evasive maneuvers, while we slink off to the north.”

Thigpen still wasn’t convinced. “But they’ll both be able to hear us when we pull in front. We’d be, what? Maybe two or three thousand yards away for either sub. We’re really quiet, but that’s way too close.”

“Correct again, we’d be too close. Both the Kilo and Song captains are boresighted toward the surface. The Song, so he doesn’t get run over by a passing merchant, and the Kilo as he’s setting up his attack. Neither sonar system can look at more than one depression/elevation angle at the same time. So we come in right off the bottom, below their sonar’s field of view. The water is shallow here, which will help hide our signature, and we have a negative sound velocity profile down to the bottom—everything is in our favor. Trust me, this will work!”

Jerry watched as Thigpen worked the problem through. He was still unsure, but his CO’s confidence overwhelmed him. Swallowing hard, Thigpen finally said, “It’s your call, sir.”

With a beaming smile, Jerry slapped his XO on the arm. Turning to Covey, Jerry ordered, “Weps, load an NAE in one of the signal ejectors. Set a two-minute time delay.”

“Aye, aye, sir,” replied Covey.

Looking back at Thigpen, Jerry nodded and said, “XO, man battle stations.”

Once the crew was at general quarters, Jerry explained his plan to the control room watchstanders. He took extra care to make sure everyone understood what they were about to do, and why. The junior officers were awestruck and excited; the more senior ones were apprehensive. Even though the odds were very much in their favor, this was not a risk-free evolution.

As soon as the Kilo was on their starboard beam, Jerry made a sharp turn to the northeast and moved North Dakota into the Vietnamese boat’s baffles. Blocked by the submarine’s hull, the large cylindrical array in the Kilo’s bow couldn’t hear them and Jerry accelerated to fifteen knots.

It was a long, slow overtaking geometry, but twenty minutes later, the Kilo was five hundred yards to port and a hundred feet above them. With only fifty feet between the hull and the sea floor, Jerry slowed to ten knots as North Dakota slowly pulled in front. For the next six minutes, hardly a sound was made in control; even the watchstanders’ breathing was hushed. When they reached the designated point, Jerry ordered the NAE launched, turned north, and slowly increased speed to twelve knots. Thigpen started a stopwatch on the command workstation and called out the time in fifteen-second intervals.

“Fifteen seconds… ten, nine, eight…” Thigpen’s voice was just above a whisper.

“Pilot, ahead standard,” Jerry commanded.

“Ahead standard, Pilot, aye, Captain. Maneuvering answers ahead standard.”

“Very well, Pilot.”

Seconds later the NAE fired up and began rotating the rings of ball bearings inside at high speed. The noise it made was deafening.

Both the Kilo and Song were taken by complete surprise. The Kilo popped a countermeasure of its own, and accelerated to the southwest. The Song stopped snorkeling and headed north at flank speed. Not a single torpedo had been launched.

In North Dakota’s control room, a low cheer broke out as soon as it was clear the two hostile submarines had bolted in opposite directions without firing a shot. The plan had worked perfectly.

“Well done, all! Your execution was flawless,” gushed Jerry, clearly pleased with his crew.

“I think there are some drawers that need a changin’,” remarked Iwahashi cheerfully.

Thigpen shook his head. “Mine would if I was blasted out of the blue with Metallica at 150 dB!”

Jerry was still smiling. “Attention in control, we’ll stay in contact with the Kilo as it finishes its evasive maneuvers. After it settles down, we’ll get Fargo back in contact and then we’ll head back east. Carry on.”

A visibly relieved Thigpen moved closer to Jerry. “Congratulations, Skipper, your plan worked.”

“Thanks, XO. I was confident it would.”

Thigpen shook his head again. “You know, Captain, I think you’re a little too smart for your own good.”

Jerry laughed, but he heard his XO’s message nonetheless. “After Fargo is back in trail, we’ll break off and report in. This should make the commodore’s day after all the bad news we’ve sent in.”

“I don’t know, sir,” Thigpen replied. His face was skeptical. “Somehow I don’t think our new commodore is going to be all that pleased.”

Jerry was puzzled. “What makes you think that, Bernie? Neither side had a clue we were here, and we prevented more deaths. Surely that has to be a win in anybody’s book. I think once I explain it to Captain Simonis, he’ll agree it was the right thing to do.”

Jerry couldn’t have been more wrong. Simonis was absolutely furious with his new commanding officer, and he wasted no time in saying so.

“What were you thinking, Captain? Your orders were to remain undetected, observe and report! Not to reveal yourself by interfering!”

Jerry swallowed hard; the severe dressing-down had caught him by surprise. Simonis’s reaction was immediate, almost visceral. Jerry had badly misjudged his new boss’s risk tolerance.

“Commodore, I am confident neither side knew a U.S. submarine was in the vicinity. My approach made the best use of the tactical situation and the environment; the other two submarines have inferior sensors and were too engrossed in what they were doing to notice our presence.” Jerry’s attempts at explaining his actions only succeeded in making Simonis angrier.

“Notice your presence!? Even if they didn’t pick up your boat, they couldn’t help but notice the countermeasure!” screamed Simonis. “How can you possibly defend this flagrant violation of your orders?”

Jerry took a deep breath, calming himself. He would have only one chance to get his point across. Responding with an angry tone would simply make matters worse. “Sir, as I stated in my report, an NAE is virtually identical to the Russian MG-24 countermeasure that both Vietnam and China have on their submarines. I took special care to make sure the NAE was placed between the two subs; their first impression would be that the other guy popped the decoy. The mutual evasion conducted by both boats, with no attempt to follow up and acquire me, proves that assumption was correct.”

“And if they recorded the acoustic signature, they’ll be able to discover the countermeasure’s identity after conducting post-processing,” Simonis countered.
