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 CB 2 F, 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 rocketâs exhaust; the craftâs flattened shape, complete with upswept stabilizer tips on the ends of the circular âwings,â 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 consultantâs 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 subâs pilot pulled back on the joystick controlling the vesselâs 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.
âThis is why you retired here, isnât it, sir?â he asked. âTo be able to play with the Navyâs high-tech toys? Maybe keep doing a bit of exploringâ¦new worlds, and all that?â
âOh, 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.â He grinned. âBut Iâm damned glad it did.â
âHey, Mr. Garroway?â the pilot said. âWeâve got company.â
Mark frowned, rolling sideways on his couch to look up at the pilot. âWhat is it?â
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.
âReads as a commercial teleoperated job. Looks like one of the Atlantis remotes.â
âAnyone ever tell those jokers these are restricted waters?â Mark growled.
âIt looks like a commercial job,â the pilot repeated. âBut it could be our friends again.â
âWhat friends?â Jeff asked.
âSomeoneâs been very interested in our activities down here,â Mark explained. âNow, 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.â
Jeff frowned. âChinaâs overseas intelligence bureau? Why would they be using a commercial teleop drone?â
âProbably because Atlantis is close by, with remote drones that can innocently stray into government-restricted waters âby mistake.â And they can link in from anywhere, remember.â
Atlantis was another seaquarium resort, much like Oceanus but located in Florida, just south of West Palm Beach. Three hundred kilometers wasnât exactly âclose by,â but it was close enough that teleop drones could operate comfortably for extended periods.
âRange?â Mark asked Carver.
âSeventy meters.â The whine of the Mantaâs jet drive increased as the SEAL sub driver boosted the power. âSixty. Weâre closing.â
Outside, all was still in
