“I thought these subs had a thirty-day endurance,” Jeff said.
“They do,” Mark said, “when they’re fully supplied, which this one is not. Even so, we have expendables enough to stay down for three or four days, at least. But that’s not what’s affecting our deadline. General Altman’s scheduled to arrive in another hour, and we should be topside to meet him, don’t you think?”
“Damn,” Jeff said, continuing to watch the soft-glowing fireworks beyond the port. “I could stay down here for days!”
Mark chuckled. “Yeah, I know exactly what you mean.”
Jeff Warhurst glanced sideways at the older man, at the rugged face in profile faintly illuminated by the red-hued glow of the bridge lights. Mark Garroway was seventy-one years old but showed no sign at all of slowing down, and his face was alive now with pleasure and wonder. He looked as excited as Jeff felt, for all that he was thirty-two years older.
The man was a legend in the Marines—“Sands of Mars” Garroway, the then-Marine Corps major and electronics expert who’d led a small band of Marines across 650 kilometers of the Vallis Marineris back in ’41 to defeat a UN garrison at Mars Prime and go on to recapture the U.S. xenoarcheological base at Cydonia.
Jeff had been a Marine since 2050—seventeen years now—and had all but worshipped Garroway as his personal hero for longer than that. It was still a little hard to realize that he was lying next to the hero of Garroway’s March…in an environment even more alien, in most ways, than the frozen surface of Mars.
“I guess this is all pretty old to you. You probably get tired of this after awhile, huh?”
“What?” Garroway said, startled. “Tired of this? When I do, I’ll be tired of life!”
From what Jeff had heard, the elder Garroway hadn’t slowed down much at all in the past quarter-century. Shortly after his return from Mars, he’d worked as a consultant with the Japanese, helping to make sense out of the flood of new technology arriving from the ET finds on Mars and the Moon. After that, he’d retired here, to the Bahamas, to open his marina, but even then he continued to work as a government consultant. AUTEC—the big U.S. submarine testing and research station on Andros Island—was only a few kilometers down the coast. With the building of the Bahamas seaquarium next door at Mastic Point twelve years ago, Mark Garroway had become both moderately wealthy and something of a public figure. Garroway’s marina had been offering both realworld and virtual commercial submarine tours of the reefs for tourists for years now; his undersea tour service was a part of the Oceanus Seaquarium’s exhibits and one of the most popular tourist attractions in the Islands.
This submarine, though, was not one of the tourist boats, not by about five thousand meters. Nicknamed Manta, the boat was a blunt, stubby, cigar shape eight meters long melded smoothly with rounded wings that gave it an elongated saucer look. Her hull was jet-black carbon-boron-Bucky fiber weave, or CB2F, a process back-engineered from ET finds on the Moon, and stronger by a factor of five than anything based on purely terrestrial materials processing. The boat was driven by a magnetohydrodynamic jet, an MHD drive that compressed water drawn through intakes forward and expelled it aft like a rocket’s exhaust; the craft’s flattened shape, complete with upswept stabilizer tips on the ends of the circular “wings,” was that of a lifting body designed to literally fly through water as an aircraft flew through the air. Originally developed by the U.S. Navy for abyssal trench research and exploration, the Manta could dive to depths in excess of ten kilometers, enduring hull pressures of well over a ton over each square centimeter of its hull. Mark Garroway had been asked to earn his consultant’s pay this month by evaluating the Manta for use as an undersea transport for Marine raiding parties. And Jeff was here because of Project Icebreaker.
As the sub’s pilot pulled back on the joystick controlling the vessel’s attitude and increased thrust with a shrill, whining hum, the Manta began rising through the darkness. Something like a golden, shell-less snail flew past on undulating wings, leaving in its wake a faintly phosphorescent trail. The life here, Jeff thought, just a few hundred meters beneath the surface of the Atlantic Ocean, was as alien as anything that humankind might one day encounter among the stars.
“This is why you retired here, isn’t it, sir?” he asked. “To be able to play with the Navy’s high-tech toys? Maybe keep doing a bit of exploring…new worlds, and all that?”
“Oh, in part, I guess. Though I never did much in the way of exploring, even during my deployment with the MMEF. When I got out of the Corps, mostly what I wanted was to run my own marina. Oceanus and the rest just sort of happened.” He grinned. “But I’m damned glad it did.”
“Hey, Mr. Garroway?” the pilot said. “We’ve got company.”
Mark frowned, rolling sideways on his couch to look up at the pilot. “What is it?’
The helmeted man touched a control on the arm of his chair, and a monitor on a console beneath the forward port lit up with a rotating, computer-drawn view of a small, twin-outrigger submarine with a large, high-pressure viewing bubble.
“Reads as a commercial teleoperated job. Looks like one of the Atlantis remotes.”
“Anyone ever tell those jokers these are restricted waters?” Mark growled.
“It looks like a commercial job,” the pilot repeated. “But it could be our friends again.”
“What friends?” Jeff asked.
“Someone’s been very interested in our activities down here,” Mark explained. “Now, Carver here is a Navy SEAL and suspicious by nature. But sometimes it pays to be paranoid. We think it might be the Guojia Anquan Bu, keeping tabs on our deep-submersible work.”
Jeff frowned. “China’s overseas intelligence bureau? Why would they be using a commercial teleop drone?”
“Probably because Atlantis is close by, with remote drones that can innocently stray into government-restricted waters ‘by mistake.’ And they can link in from anywhere, remember.”
Atlantis was another seaquarium resort, much like Oceanus but located in Florida, just south of West Palm Beach. Three hundred kilometers wasn’t exactly “close by,” but it was close enough that teleop drones could operate comfortably for extended periods.
“Range?” Mark asked Carver.
“Seventy meters.” The whine of the Manta’s jet drive increased as the SEAL sub driver boosted the power. “Sixty. We’re closing.”
Outside, all was still in complete blackness, save for the constellations of luminous deep-sea life. According to the readouts, they were at 495 meters depth now, with an outside pressure of nearly fifty atmospheres squeezing at the hull. A tense minute passed as the Manta climbed through the high-pressure dark.
“They’re running,” Carver said. “They know we’re on to them.”
“Run ’em down!” Mark said.
“Range ten meters,” Carver said. “I’m gonna hit the lights.”
“Do it,” Mark replied. A harsh white glare stabbed through the sea outside, turning drifting bits of detritus into a blizzard of glowing flecks. Ahead, a bubble-topped vessel less than a meter long, with twin outriggers and a yellow and red paint scheme, twisted in the Manta’s beam.
“That’s an Atlantis boat,” the pilot said.
“It’s tiny,” Jeff said.
“Unmanned,” Carver told him. “Someone’s linked in through its cameras and other sensors and is piloting it from
