Jerry paused by the UUV control console. “Anything from Fargo?”
“Sorry, Skipper, nothing,” replied the petty officer.
Sighing deeply, Jerry gave the enlisted man a solid pat on the shoulder and made his way back to the CWS—the starting point for yet another lap. Thigpen watched as his captain beat a well-trodden path in the linoleum deck, and after almost two hours, his patience was gone. Inching closer to Jerry he whispered quietly, “If you want the watch, Captain, I don’t mind turning it over. I have plenty of other stuff to do.”
Jerry closed his eyes and took a deep breath. Thigpen’s tone and the use of the word “captain” were a clear indication of his frustration. It was Thigpen’s watch as the command duty officer, Jerry’s had ended at midnight, but his silent lingering was putting everyone in control on edge.
“Sorry, XO,” said Jerry. “It just grates me that we can’t find this guy.”
“Join the crowd, sir,” Thigpen responded flatly. “But with all due respect, Captain, your rambling about is driving everyone in control crazy; and you know how short a trip that is for me.”
Thigpen’s quip took most of the bite out of his comment, but the message was loud and clear. Jerry was distracting the watchstanders with his moping about, and as CDO, Thigpen was completely in the right to put a stop to it.
“All right, all right, XO,” replied Jerry, chastened. “I’ll… just sit over here if you don’t mind.” Jerry pointed to one of the empty fire control chairs.
“As long as you behave yourself,” jabbed Thigpen sternly. Lymburn desperately tried to stifle a laugh, but ended up emitting a loud snort instead.
“Something wrong, Q?” Jerry asked with mock annoyance.
“No, sir. Just clearing my throat. Ahem, Ahem,” replied the young lieutenant, smiling.
“Hmph! Insubordinate twits,” Jerry muttered.
INS Chakra
50 km West of Hainan Island, South China Sea
“Report, Number One,” demanded Samant as he strode into central post. He’d ordered Chakra to action stations just before he left the torpedo room, where he had supervised the loading of the first six land-attack cruise missiles.
“Yes, Captain, all compartments report they are at action stations. All torpedo tubes are at action state, with the exception of opening the bow caps. The target’s coordinates have been successfully loaded into the missile’s guidance computers,” Jain answered promptly.
“Did you double-check that the missiles’ navigation systems are selected to use Beidou satellite guidance?”
Jain nodded vigorously. “Absolutely, sir! The Klub missiles will use the Chinese’s own navigation satellites to guide them to their targets.”
“Excellent,” smiled Samant with satisfaction. When India first purchased the Russian Klub missile system, the deal included the 3M-14E land-attack cruise missiles. As received, the 3M-14E missiles’ onboard navigation system could only use the American GPS and Russian Glonass satellite navigation systems. However, before the missiles were loaded on Indian submarines, DRDO technicians replaced the Russian receiver with a home-built unit that could use all four satellite navigation systems, including the military signal from the Chinese Beidou, or “Compass” system.
Indian cyber spies had stolen the receiving chip design from a Chinese vendor’s network, and when it was exploited, discovered that the Beidou system had an accuracy degradation feature similar to the U.S. Global Positioning System’s “Selective Availability.” The Ministry of Defense ordered the chip to be reverse-engineered and installed in all Indian military navigation systems and applicable weapons—particularly missiles. The wisdom of this decision was justified early in the war.
Soon after the Littoral Alliance announced its existence, the CMC ordered the jamming of GPS and Glonass signals over selective areas of the Chinese mainland. The degradation to the satellite’s guidance signals reduced the effectiveness of some of the alliance’s early missile strikes, but once India passed on the schematics and some examples of the new receiver to her allies, Vietnamese and South Korean cruise missiles were soon fitted with the modification. The Chinese were just about to find this out.
“Helmsman, make your depth twenty meters. Prepare for a safety sweep,” announced Samant. “Open bow caps on all torpedo tubes. Stand by to fire, firing sequence tubes one through six, five-second intervals.”
USS North Dakota
“CDO, new contact, designate Sierra-five two, bearing zero three eight,” cried the sonar supervisor. “Contact is faint, just a few mechanical transients.”
Thigpen turned and looked over his shoulder. “Do you have a range?”
The sonar supervisor shook his head. “No, sir. I only got a few hits on the TB-33, definitely mechanical in nature. Nothing on any of the hull arrays.”
Jerry had shot out of the chair as soon as he heard the news and stood next to Thigpen. “Sounds like our boy, XO.”
“It’s a good bet, Skipper.”
“Hell, I’d take any bet right now. This guy is pretty cagey. If we’ve picked up mechanical transients, it’s only because he’s about to shoot someone.”
“But that’s just it, Skipper,” complained Thigpen. “There is nothing else out there even close to that bearing to shoot at!”
“Not even a Chinese sub?”
“No, sir, not that we can see. And we’ve had no problem picking up lots of transients and strong tonals from Chinese boats long before we get broadband contact.”
“So, if it isn’t a surface ship, or another submarine, then…” Jerry just stopped, letting his statement dangle. He had a coaxing expression on his face, pushing his XO to finish the thought. Thigpen caught on immediately.
“Wait a minute, are you suggesting…”
“That’s what I’m thinking.”
“Oh, shit,” Thigpen uttered quietly.
“Yup, that’s about right,” concluded Jerry.
Lymburn looked back and forth at the two men, totally confused by their cryptic conversation. “What!?” she exclaimed. “What’s the matter… sirs?”
Thigpen held up his left hand, signaling for her to wait. “Patience, Grasshopper,” he said as he pivoted back toward the command workstation. “Pilot, right full rudder, steady on course zero five zero. All ahead standard.”
As the pilot responded to the orders, Thigpen grabbed an interior communications handset and punched in the number for the engineering officer of the watch. “Maneuvering, Conn. Shift reactor coolant pumps to fast speed. Stand by for flank bell.”
North Dakota heeled slightly as she accelerated through the turn. Swinging toward the contact, and gradually picking up speed, she began to close the distance.
Thigpen shook his head as he looked at the electronic plot on the port VLSD. He was not happy with the geometry. Glancing over to Jerry, he said, “Assuming it’s our friend, and assuming he’s still headed in a northerly direction, I’m biasing us to come in behind her. But I really dislike putting whatever it is in the towed arrays’ forward beam. Our bearing data will suck.”
“Do we have a choice?” Jerry asked stoically.
Thigpen sighed. “No, sir.”
“Then we don’t have a problem, XO.”
“Yes, sir,” he replied. Then more defiantly added, “But I still don’t have to like it.”
Jerry rolled his eyes; Thigpen was just being stubborn. “Very well, XO, permission granted to not like it.”
“Thank you, sir,” replied Thigpen, satisfied.
Lymburn, sensing a break, moved closer. “Captain, XO, I still don’t understand what’s going on.”
“Ah, yes, sorry about that, Q,” Thigpen apologized. “Here’s the deal. We think Sierra-five two is the Indian Akula. If so, then the mechanical transients we’ve detected are likely torpedo tube preparations. As we hold no other contacts near the bearing, the Skipper is guessing that our friend out there is about to…”
“Launch transients!” sang out the sonar supervisor abruptly. “One weapon… two, solid rocket ignition. XO, Sierra-five two is launching missiles.”
“…launch missiles,” said Thigpen dryly, completing his sentence. He then leaned forward, and acknowledged the report. “Very well, Sonar Supervisor. Did we get a range?”
“No, sir. Sierra-five two is still in the wide aperture arrays’ baffles. Contact is drawing left, bears zero three five.”
“Sonar, were you able to get a weapon count?” interrupted Jerry.
“Not a good one, Skipper. At least two missiles, probably more. The noise from the rocket motors drowned everything else out.”
“Orders, Skipper?” asked Thigpen.
“He’s not done yet, he’s probably reloading for another salvo,” Jerry opined. “Time to let him know we’re here, XO. Put the spurs to her.”
“Aye, aye, sir!” Thigpen responded enthusiastically. “Pilot, left standard rudder, steady course zero three five, all ahead flank. Sonar, stand by to go active on Sierra-five two.”
INS Chakra
“First missile salvo launch complete, Captain. Bow caps are closed on tubes one through six, and the loading of the second salvo is under way,” reported Jain.
“Very good, Number One, but tell the boys in the bomb shop to be quick about it. We just broadcasted our location to the world, and I have no desire to tarry here more than is absolutely necessary,” Samant demanded.
