Poseidon's Arrow

The President nodded. As it lay on huge supporting blocks, the three-hundred-and-seventy-seven-foot-long hull towered over them.

“She’ll be a great addition to our arsenal. I thank you for giving me the opportunity to see her up close.”

A granite-faced admiral named Winters stepped forward.

“Mr. President, while we were happy to have you preview the North Dakota, she was not the reason we asked you up here.”

The President took off a white hard hat affixed with the presidential seal, handed it to the admiral, and wiped a bead of sweat from his forehead.

“If a cold drink and a touch more air-conditioning can be worked into the bargain, then lead on.”

He was escorted across the building to a small door guarded by a uniformed security man. The door was unlocked, and the presidential group led in one by one, their faces captured by a video camera above the sill.

The admiral flicked on a bank of overhead lights, illuminating a narrow bay that stretched nearly four hundred feet. The President saw another submarine in a state of near completion, but this vessel was like nothing he had ever seen before.

Roughly half the size of the North Dakota, it sported a radically different design. Its unusually narrow jet-black hull tapered sharply at the bow. A low, egg-shaped co

The design reminded the President of a giant manta ray he’d seen while fishing off Baja California.

“What on earth is this thing?” he asked. “I wasn’t aware we were building anything other than the Virginia class boats.”

“Sir, this is the Sea Arrow,” the admiral said. “It’s a prototype platform developed under a secret R & D program to test highly advanced technologies.”

Cerny turned on the admiral. “Why wasn’t the President informed of this program? I’d like to know how it was funded.”

The admiral stared at the aide with the warmth of a starving pit bull. “The Sea Arrow was built with Defense Advanced Research Projects Agency and Office of Naval Research funding. The President is presently being informed of its existence.”

The President ignored them and strode along the vessel, peering at the odd appendages along the hull. He studied a concentric circle of small tubes that sprouted off the bow, then made his way aft, noting the sub had no propellers. He gave Winters a questioning look.

“All right, Admiral, you have my curiosity. Tell me about the Sea Arrow.”

“Mr. President, I’ll pass that task to Joe Eberson, who heads up the project. You met Joe earlier. He’s DARPA’s director of Sea Platforms Technology.”

A bearded man with studious eyes worked his way to the front of the group. He spoke in a measured tone with the hint of a Te

“Sir, the Sea Arrow was, or is, being built as a multigenerational leap in undersea technology. We’re bypassing the traditional development process by integrating a range of cutting-edge technologies and advanced theories directly into the construction. We started with a pla

The President nodded. “So tell me about all these odd appendages. She looks like some flying creature from the Jurassic age.”

“Let’s start at the stern. You’ll notice she has no propeller.” Eberson pointed at the rounded pods. “That’s what these two external cases are for. The Sea Arrow will be powered by a shaftless propulsion system. The North Dakota, as you saw, uses a nuclear reactor to power a traditional steam turbine, which in turn drives a shaft-mounted screw. On the Sea Arrow, we’ve gone to an external drive system, which will be powered directly from the reactor. Each of these two flared pods will contain a permanent high-intensity magnetic motor that drives a pump jet propulsion system.” Eberson smiled. “Aside from drastically reducing noise, the design frees up a tremendous amount of interior space, which has allowed us to shrink the vessel’s overall size.”

“What are these permanent magnet motors?”

“They’re an evolutionary, if not revolutionary, advance in the electric motor, made possible by recent breakthroughs in material sciences. A mix of rare mineral elements is synthesized to create extremely powerful magnets, which are then wound into high-performance, direct-current motors. We’ve invested a great deal of research in perfecting these motors—and believe they will revolutionize the way our future warships are powered.”

The President peered through a baffle on one of the pods and saw light shine through from above.

“It looks empty inside.”

“We haven’t actually received and installed the motors yet. The first is due in next week from the Navy’s research lab in Chesapeake, Maryland.”

“You sure they’re going to work?”

“While we haven’t fielded motors of this size, we are confident from our lab tests that they will provide the predicted levels of performance.”

The President ducked beneath one of the extended stabilizers, then glanced up at a pair of barrel-shaped protrusions fore and aft of the co

Eberson followed in his steps, narrating as he walked.

“The wing-shaped extensions are retractable stabilizers for high-speed operations. They automatically withdraw into the hull when speeds drop below ten knots. The tube-shaped box is a torpedo canister, capable of holding four fish on each stabilizer. The canisters can be reloaded quickly when the stabilizer is retracted into the hull.”

Eberson pointed to the two barrel-shaped objects above them. “Those are subsurface Gatling guns. They’re similar to those used on surface ships, which shoot depleted uranium pellets at rapid fire for last-ditch missile protection. Ours have been developed to fire underwater, using compressed air, for last-ditch torpedo suppression. Of course, we’re banking that most enemy torpedoes will never come near us.”

He followed the President as he stepped toward the hull.

“The co

“Doesn’t look like she’ll allow for much of a periscope.”

“The Sea Arrow doesn’t actually have a periscope, at least not in the traditional sense,” Eberson said. “She utilizes an ROV-type video camera that is deployed on a tethered fiber-optic cable. It can be released from a depth of eight hundred feet to give the crew a high-definition picture of what’s going on on the surface.”

The President continued on to the tapered bow and reached up to stroke one of the small tubes that jutted forward like a thin lance. “And this?”

“That’s the key link that will really make her go,” Eberson said. “It’s a secondary upgrade we hope to implement, based on a technological breakthrough from one of our contractors in California—”

Admiral Winters cut him off. “Mr. President, why don’t we take a quick tour aboard, then we have a short presentation to show you that should answer all your questions.”

“Very well, Admiral. Though I’m still waiting for my drink.”

The admiral hustled the group through a quick tour of the interior, where they found a streamlined interior that contrasted with the North Dakota in its sleek modernity and scale of automated systems. The Commander in Chief remained silent as he viewed the high-tech command center, the small number of plush crew’s quarters, and the odd assortment of padded seats with full safety harnesses that were positioned about the vessel.
