“This is why you’re here, Captain. A working electromagnetic rail gun will be a game-changer for the fleet; maybe for the entire war,” she said.
The rail gun represented a break point,34 a shift away from over eight hundred years of ballistic science. Instead of using the chemistry of gunpowder to shoot a metal object out of a long barrel, the rail gun used energy that came from electromagnetic forces. A powerful current ran through two oppositely charged rails on either side of the barrel. When a conductive projectile was inserted between the rails (at the end connected to the power supply), it completed the circuit. Just as the gases expelled by exploding gunpowder propelled a bullet out of a conventional gun, the magnetic field inside the loop created a burst of incredible power, called a Lorentz force,35 that slung projectiles out of the open end of the gun barrel. There were no fuses to light, but the rail gun did require a massive and reliable supply of electrical current. Without electricity, a ship with a rail gun would be like a nineteenth-century ship of the line with a waterlogged powder magazine.
“We sure could’ve used it at Pearl,” he said, thinking of the popgun they’d had on the Coronado.
“I can imagine. But I don’t plan on anyone ever being stuck in a kill box like that again. What do you anticipate the rail gun’s effect will be on fleet action?” Another test. Still the college president at heart.
“It gives us speed and range, ma’am. It slings out a shell with a velocity of more than eighty-two hundred feet per second, allowing us to strike targets out to a hundred and eighty miles. It’s a double gain. Faster than any missile and impossible to jam or shoot down.”
She nodded, but she seemed to be waiting for more.
“But more important will be their effect. The shells are small, but with that kind of speed they’ll hit with a force equaled only by the old Iowa-class battleships’ cannon shells, and those were the size of cars. It also solves the capacity and targeting problem we have with the long-range strike missiles. Even without a precise GPS location, we can lay down a pattern of fire that saturates a target set. That’s where the similarity with the old battleships holds best.”
“The Hand of God is what they called it during development,” said Admiral Murray. “I was a junior officer working on the Navy staff in the Pentagon back then, N-9 Warfare Systems. I remember the rail-gun program; officers had it all over their PowerPoint briefs when they came in. It was a cool name, but it didn’t stop us from slashing their budget when the cuts came. How are you dealing with the thermal and power management issues that bugged it then? You can’t exactly replace a melted barrel in the middle of an engagement.”
“There’s two ways to deal with the heat. This is actually not the original barrel they had problems with back then. It uses a nanostructure that dissipates the heat. Of course, we still have to be careful, but we can fire in what we call a surge strike. The power management is more complicated, and, frankly, Admiral, that’s my concern. The rail gun requires the power equivalent of a small city. This ship was supposed to be designed with that in mind, but you know how they overpromised and underdelivered.”
No other surface ship besides the Zumwalt had a power system that could generate and, more important, store the tremendous amounts of electricity required for the electromagnetic push that was the essence of the rail gun’s design. This was why the Navy had lost its original excitement over the rail-gun program once the Zumwalt class had ended. Even with a design tailored for the new weapon, the Navy’s models projected that each firing of the rail gun would require stealing energy from other systems onboard, including the ship’s propulsion.
“We are all too aware of that problem with the old defense-industrial complex,” she said. “So what are you doing about it?”
“We’re approaching it through both tactics and reengineering,” said Simmons, trying to shift his tone so that she wouldn’t think he was making excuses. “Tactically, the plan is to use the power drain to our advantage, so to speak, by building drift into the anti-detection protocols. The key is not to get boxed in again, as you put it, but to disappear in the expanse of the ocean. On the reengineering side, we’re getting good results from the new energy-dense liquid-based battery being built for the ship. It’s giving us added power beyond what the original design in the nineties envisioned. We’ve been assigned a specialist in liquid-based batteries, a woman from the University of Wisconsin. Frankly, there’s a lot riding on her expertise.”
He paused to look directly at her.
“But the answer, Admiral, is that the rail gun is power hungry. My concern is that if things do not go according to plan, we will be stuck with only bad options.”
“Captain,” she said, stressing his rank. “That’s the thing you learn as you move from an executive-officer role to that of command. It’s never about choosing the best option; it’s about choosing the least bad of the bad options.”
She paused to let her lesson sink in. Simmons thought about that day at Pearl Harbor and how she hadn’t needed to pass on that particular nugget of wisdom.
“Captain, I believe in you. And I believe in what this bastard child of a ship might accomplish. Risks that were once unacceptable to us are now the price of doing business.” Her eyes grew dark, and Simmons saw the warrior side come out of the old war-college president. “I need you to get this ship ready, because I need you to kill things out there, as many as you can, as fast as you can. I need the Directorate to feel something new: fear. You will make them feel that fear, Captain. Understood?”
Subbasement Level, G Ring, Pentagon
The door to the small conference room shut with a soft sigh and everyone in the room felt the pressure change. The naval officers there pinched their noses and exhaled to clear their ears, while the civilian scientists kept trying to swallow.
This secure space was a new design, built to defeat Directorate’s eavesdropping and network attack. The original Tank,36 the Joint Chiefs’ situation room, had been thought completely secure right up until the moment it was discovered that it had been compromised by hardware bought by a U.S. defense contractor on the cheap from a Florida subcontractor37 that turned out to be a shell company run by two college kids who were just reselling chips from a Chinese vendor. Everyone called these new chambers the Box, though the design was actually a box within a box. Between the two nanoparticle-infused sets of walls was a fluid that circulated at high speed in order to diffuse any signals or transmissions going in or out. Rumor had it the fluid was radioactive.
“Okay, then, let’s dispense with the formalities; none of us want to sit in the Box any longer than we have to,” said Admiral Raj Putnam, head of Naval Intelligence.
Links, sitting next to Darling, took his cue. “It starts in Beijing, sir. I was finishing up my assignment to the embassy—I was actually at my going-away party on my last night there. There was a Russian officer, a lifer in Beijing, whom I’d gotten to know, and he was helpful to me from time to time.”
“You mean you got shitfaced with him a few times and he was running you?” said Admiral Putnam.
“No, sir, I know the game,” said Links. “I’m not chipped, but you can check my viz and other records. That ties back to the party. As you know, everyone is either chipped or recording with derm mikes or viz or what have you. So I assumed there was no way he would say anything interesting.”
“Yes, I’ve reviewed the viz from the party myself,” said Admiral Putnam. “He didn’t.”
Links shot a look of disbelief at Darling. In the moment of silence, the womblike sound of the fluid pumping around the room seemed to intensify. Then Links cleared his throat and continued.
“It’s the context that makes our conversation interesting. As you saw, we were talking about Star Trek, the old television and film series. I’d talked about a lot of things with Sechin, but never science fiction. Usually he just gave me gossip on the Directorate’s internal politics or upcoming promotions, that kind of thing. So this stuck in my mind,” sai
d Links. “Sechin explained how proud he was that one of the characters, Chekov, was named after this Russian scientist, Pavel Cherenkov. Honestly, Admiral, I figured he was just drunk. Then yesterday, after hearing about what happened to the USS John Warner, it clicked.”
Links wondered how old the admiral was. He wore his gray hair shaved to the skull, like most of the population of the Pentagon, some kind of show of commitment to the war effort. The admiral had smooth, unblemished skin but a nose like a moon rock. He might be old enough to have watched the first wave of Star Trek movies.
“So how does his sci-fi drinking tales square with what you saw?” said Admiral Putnam to Darling.
“I believe it relates to how they targeted our undersea assets,” said Darling. “There were no Directorate submarines or surface ships in our area of operations other than the target we engaged. Nor were there any aircraft. We owned that box. Or so we thought.”
Darling chewed his bottom lip in evident frustration. “To answer your question, though, we need to give some context, which Dr. Shaw from NASA is best situated to provide.”
He turned to the man seated at his left. Shaw did not look the part of a scientist, being tall and wiry with a swimmer’s broad shoulders. He also wore an expensive suit, flashy, in the 1930s-style now back in fashion. And to cap it, he had his slender, rose-tinted viz glasses perched on his head, almost like a tiara. The intended effect, whatever it was, was lost on the admiral.
Shaw stood and began to speak as a video projection appeared behind him. The content failed to match the vibe he gave off.
“When a photon exits a vacuum and enters a dielectric medium at a speed greater than the phase velocity of light, a wonderful result occurs, which proved to be key to science’s understanding of everything from the nature of black holes to the stars. Let us begin with the mathematical foundations.”
As Shaw scribbled out an equation that was projected on the wall of the Box, Admiral Putnam turned to the two officers and said, “Gentlemen, I don’t have time for a dissertation defense; we have a war to win. How does this link to Cherenkov and the subs?”
“He’s coming to it, sir,” Links responded. “Dr. Shaw, perhaps the metaphor you used to explain this to us might be more helpful now than the math.”
“Ah yes,” said Dr. Shaw. “You are familiar with what happens when an aircraft breaks the sound barrier by traveling faster than the speed of sound: A sonic boom38 trails behind it. Cherenkov radiation is that, in a sense, playing out at the electron level. What we know as light speed is possible only in a vacuum. When light travels through different mediums, such as water, it is slowed down by the matter in those mediums. Thus, it is possible for charged particles to travel faster than light through those surroundings. These particles, however, are still interacting with the same medium, exciting the molecules in it to release photons that pile up behind. Thus, the boom is a sort of cone traveling behind the subatomic particles. In nuclear reactors, which I understand you are interested in, the particles move away at higher speeds than light does, giving the wonderful blue glow you might be familiar with. That is Cherenkov radiation.”
Links jumped back in, knowing he was going to lose his audience if he didn’t intervene. “And, sir, that may be connected to another mystery. In the antisubmarine group, we’ve been focusing on the Directorate offensive at Pearl Harbor and then out at sea. But the attack, of course, began in space. And when you speak with our DIA colleagues about that, they’ll tell you that one target didn’t make sense, a particular NASA research satellite. We’d assumed that the Directorate had gotten their intel wrong and thought it was a clandestine spy satellite. That’s why Dr. Shaw is here. Doctor, could you tell the admiral what your project at NASA focused on?”
“It was originally designed to collect Cherenkov radiation for research into the origin of black holes. But because NASA wanted to show Congress ‘tangible results’”—Shaw put that phrase in air quotes, as if to show his disdain for applied research—“it was also used to study nuclear power plants and the real and potential dispersion of radiation after events like the Fukushima and Maine Yankee incidents.”
Darling cut in. “So, sir, I ran down the old Pentagon budget funding for R and D programs and found that back in the twentieth century, the Office of Naval Research did some studies that showed that tracking a reactor via the Cherenkov radiation it emitted was theoretically possible. But the subject was never really explored. It wasn’t just that the project had a low likelihood of success; it was that even if it worked, there wouldn’t be much of a payoff for us. Our entire sub fleet was nuclear, while the Russian and Chinese subs that were the most problematic for us were the quiet, diesel-driven ones. There were no incentives for investing in that kind of research. ONR assumed that no one other than us was advanced enough to do it, and strategists worried that if we made the effort, well, the research might get out, and we would just be doing the other side a favor.”
Links jumped back in. “We have to conclude that they made a breakthrough and discovered how to track the Cherenkov radiation, which allowed them to de-stealth and target our submarines, as well as anything else powered by a nuclear reactor. And that solves both mysteries, the attacks at sea and the targeting of Dr. Shaw’s satellite. Because if you and the other side both had that ability, you would want to make sure the other guys lost it. You’d take it away from them, even if they hadn’t known they’d had it in the first place.”
The admiral didn’t respond for a full ten seconds. But his jaw clenched and a single bead of sweat formed at his temple. Then his words poured out in the quick cadence of someone who cannot quite believe what he is saying and so wants to get it out as fast as possible.
“This theory sounds like an improbable mix of drunken gossip and answers looking for questions. Which means it’s probably correct. And if it is, we have a very, very serious problem.”
Ka’ena Point State Park Beach, North Shore, Hawaii Special Administrative Zone
Major Conan Doyle aimed for the break in the reef, navigating the standup paddleboard out through the mellow swell. The Boeing D-TAC microcomputer strapped to her forearm vibrated, indicating she was close to the rendezvous point. She’d been wearing the standard-issue black plastic device the morning of the invasion, part of the emergency kit used to communicate securely with downed pilots. Three days after the convoy raid, it had suddenly pulsed with an incoming message.
A quick scan of the stars overhead, the shore behind her, and the jet-black ocean farther out showed nothing.
Had she incorrectly decoded the message? She dropped to her stomach and used the paddle to hold the board against the current, feeling a sharp hunger pang as she lay prone. She should have taken a blue before she left, but she wanted to conserve them.
The microcomputer had directed her to this location. Earlier, Nicks had revealed that the group had it at four-to-one odds that it was a trap.
“That’s why God gave us grenades,” Conan replied.
And so here she was, exposed. “The real reason you want to go,” Nicks had said, “is so you can wash your clothes.” That was true. She’d paddled out barefoot but kept on the pants that she’d worn for two months straight.
A twitch beneath the surface caught her attention. Something had moved. Something big.
The innate animal sense of being near something bigger and more powerful chilled her immediately and blocked out her hunger pangs. It was like pounding a handful of stims. Doing that wasn’t her style, though. Everybody was different. Some people needed stims when they entered the breach. Others needed focus. Beta-blockers worked best for her, as she was naturally keyed up enough.
She held herself steady on the board, fighting to keep her legs from shaking. Another dark glimmer beneath the surface. A faint eddy whirled in front of her.
Even if she’d had a gun, she couldn’t have shot it. Directorate sensor balloons would vector a patrol to the area, and she’d be on the rack within an hour as Chinese
and Russian interrogators cut her open and pumped her full of drugs. Combat medics had their golden hour39 to save a life. The Directorate interrogators had their golden hour to exploit it. Or so she’d heard. It would be better to die here, alone in the jaws of a giant, than be rent into pieces, physically and mentally, by the opposition.
The water stirred maybe twenty feet from the board’s nose as the dark form closed in. This was it, then.
Doyle got to her knees and changed her grip on the paddle; now she wielded it like a sword. The irony, she thought, that Conan had no real blade when she needed it most.
A dark fin sliced the water’s surface. She raised the paddle over her head. At least, she thought, her last act as a Marine would be a violent one.
She brought the paddle down with all her might just as the wave glider’s tubelike hull broke the surface of the water. The paddle bounced off the hard black plastic, and Doyle fell off her board and into the sea. She found herself swimming alongside the manta-ray-shaped drone, running her hands over it to convince herself it was not a shark. These nearly undetectable vehicles40 used almost no electricity. They relied on the ocean waves’ energy, rather than traditional engines, to drive them forward. Doyle’s D-TAC buzzed again to indicate that the wave glider had established a network connection with the microcomputer. A faint green message reported it had downloaded a series of files, and then another message told her what to do.
To open the cargo hatch, she first had to pull off a collection of trash hung on the vessel’s foils. The drone must have transited through the Great Pacific Garbage Patch.41 Inside the vessel’s hold were two waterproof duffle bags. The way their camouflage pattern shifted to match the rippling ocean surface and then the paddleboard’s deck made it clear something important must be inside.
