It was an impressive display, though Johnnie knew the vessel's gun armament was minor compared to that of the hydrofoil gunboats whose duty was to keep hostile torpedoboats from pressing home their attacks on the main fleet. And compared to a dreadnought of sixty, eighty, or a hundred-thousand deadweight tons. . . .
The hydrofoil's real defenses weren't her guns, of course, or even her speed—though her ability to maintain seventy knots as long as there was fuel for the thrusters was certainly a help. The thing that had kept L7521 alive through previous battles and which might save her again was the fact she was so hard to see.
Powered aircraft played no part in the wars which puffed in brief fury across the seas of Venus like so many afternoon squalls. No combination of altitude and absorbent materials could conceal from modern sensors an aircraft's engine and the necessary turbulence of powered flight. And after the quarry was seen—
Battleships and cruisers carried railguns as secondary armament. The slugs they accelerated through the atmosphere hit at a significant fraction of light speed; significant, at least, to anything with less than a foot of armor plate to protect it.
No powered aircraft could survive more than three seconds after coming within line of sight of a hostile fleet. Gliders, travelling with the air currents instead of through them and communicating with their carrier through miles of gossamer fiber-optics cable, were a risky but useful means of reconnaissance; but under no circumstances could a glider become a useful weapons platform.
Light surface craft could be designed to carry out most of the tasks of an attack aircraft and survive.
Survive long enough to carry out the attack, at any rate. War is a business of risks and probabilities.
The advantage a boat had over an aircraft was the medium in which it operated. Unlike the air, sea water is neither stable nor fully homogeneous. Swells, froth, and wave-blown droplets all have radically different appearances to active and passive sensors.
If the vessel was small—in radar cross-section—over-the-horizon systems could not distinguish it from the waves on which it skittered. Look-down Doppler aircraft radars were a technically possible answer, but an aircraft with a powerful emitter operating was even more of a suicide pact for its crew than an aircraft that
wasn't
calling attention to itself for a hundred miles in every direction.
Torpedoboats like L7521 were skeletonized blobs built of plastics which were transparent through much of the electro-optical band. Their only metal parts were in their gun mechanisms and powerplants, both of which were shielded by layers of radar-absorbent materials. If a hostile emitter did manage to lock on at short range, the little vessels mounted an electronic suite that could be expected to spoof the enemy for up to ten seconds—
Long enough to drop all six torpedoes before counterfire ripped the launch platform to shards of plastic and bloody froth.
The best countermeasures were teams of similarly-designed hydrofoil gunboats to extend the fleet's sensor range. Vicious battles were fought on the rolling wastes of No-Man's-Sea between opposing fleets. The gunboats' heavy armament meant that these blazing encounters almost always spelled death to the torpedoboat—but a regularly-spaced line of patches across L7521's main hull proved that she'd survived once; and therefore might survive again.
"Sir," said the young officer in the central cockpit, nodding to Captain Haynes. "Sir . . . ," and a nod for Commander Cooke.
The hydrofoil's cockpit had seats for four and room for several more standees. It looked like the best place to stay reasonably dry and still see what was going on, though the countermeasures/torpedo control station within the main hull forward was probably more comfortable.
Seamen among the passengers were already snapping lifelines to the vessel's railing. The small-boat men seemed cheerful, but the battleship sailors were grumbling seriously.
"Morning, Samuels," said Uncle Dan. "Get me a couple helmets and you can stand down the forward watch for this run. I'll take the gun tub with Recruit Gordon here."
The young officer's face blanked to wipe his incipient frown. "Ah, sir . . ." he said. "One of the scout gliders thought he saw some activity along our route back. I think I'd like to keep a qualified crew at the weapon stations."
"Ensign Samuels," said Dan sharply, "I was qualified on hydrofoil twin-mounts before you were out of diapers. Commo helmets, if you please."
Captain Haynes had appropriated one of the cockpit seats. He looked up from the control console with an unreadable expression. Johnnie expected him to speak, but apparently the XO wasn't willing to argue against the privileges of rank—even when it was Commander Cooke's rank.
The hydrofoil's commander gave Dan a flustered salute. "Aye-aye, sir," he said.
He turned and called forward, "Alexander and Jones, you're relieved. Give, ah, give your commo helmets to the Director of Planning and his assistant."
Two ratings had climbed out of the forward position before Johnnie and his uncle reached it along the narrow catwalk.
One them grinned as he handed Johnnie a helmet made of the same gray-green plastic as the torpedoboat itself. "Enjoy yer ride, kid," the seaman said. "It's just like the battlewagons—showers in every stateroom."
Johnnie donned the helmet and started to sit in the low-mounted assistant gunner's seat. The AG's job was to pass fresh magazines and take over if his Number One—necessarily more exposed—bought it. Dan smiled and waved his nephew to the main seat instead.
"Go on," Dan said. "You've got simulator hours on the twins, don't you?"
"Yeah, but I'm not qualified—"
The older man waved a hand in dismissal. "
I'm
qualified to judge," he said. "Maybe you'll—"
He touched the keypad on the side of the helmet he wore. "Set your helmet on 3," he continued, his voice now coming through the earphones in Johnnie's helmet. "That'll give us some privacy."
As Johnnie obeyed—hesitating, but managing to find the correct button without taking the helmet off to look at it—Dan continued, "As I say, maybe we'll find you something more interesting that a simulator target."
L7521 got under way, rumbling away from the dock on the single thruster at the stern of its main hull. The outriggers, one at the bow and two at the stern—the latter with thrusters of their own—began to crank down into the sea. When waves clipped the foils' broad vees, rainbows of mist sprayed about the vessel.
Johnnie thumbed the gunsight live. The holographic sight picture was exactly like that of his simulator back in Wenceslas Dome: a rolling seascape onto which the data banks would soon inject a target.
Reality might do the same.
The vessel worked up to about ten knots on the auxiliary thruster alone. The bow started to lift in a sun-drenched globe of spray. The stern-foil powerplants cut in and L7521 surged ahead.
"You think we're going to have to fight on the way to the base, then?" Johnnie asked, wondering if his uncle could hear him over the wind and drive noise.
The helmets did their job. Dan's chuckle was as clear as it had been in the Senator's office. "I think there's usually something on the surface of Venus that'll do for target practice," he said. "Why? Are you worried?"
Johnnie checked the traverse and elevation controls in both handgrips. The action felt normal, natural. The simulator had prepared him very well, though the amount of vibration through the seat and the baseplate was a surprise.
"I'm . . . ," Johnnie said. The wind pushed his head and shoulders fiercely, but the boat continued to accelerate. They must already be at fifty knots, though the absence of fixed objects disoriented him.
"Uncle Dan," Johnnie said, "I'm afraid I won't be good enough. I'm afraid I'm going to embarrass you. . . . But I'm not afraid of fighting."
"That's good, lad," Dan said in a matter-of-fact voice. "Because you're going to be fighting. If not on this run, then real soon.
That
I can promise."
The vibration of L7521's drives and hull reached a harmonic. For a moment, it seemed as though the vessel herself was screaming with mad laughter as she rushed toward the western horizon.
Rolled to starboard, rolled to larboard,
when the surge was seething free,
Where the wallowing monster spouted his
foam-mountains on the sea.
—Alfred, Lord Tennyson
Johnnie reflexively set the gunsight controls to search mode—then realized he wasn't alone in a simulator where he'd be graded by electronics. He looked at his uncle in embarrassment, poising his hand to switch back to direct targeting.
Dan raised an eyebrow.
"Ah, was that right?" Johnnie asked. "The sights?"
In search mode, the holographic sight picture relayed the image from the masthead sensors above the cockpit, the highest point on the little vessel. At the moment their image was a three-dimensional radar panorama: 320
O
of empty sea, with a sprinkling of low islands on the northern and northwestern horizon.
"Sure," said his uncle. "Isn't it what your simulator told you to do?"
"Yeah, but . . ."
L7521 was running at speed, slicing over the swells like an amusement-ride car on rails. Froth and flotsam snapped by to either side of the hydrofoil at startling speed, contrasting queasily with the large-scale hologram which scarcely changed at all.
"John, I designed your training programs myself," Dan said. "They couldn't cover everything, but what they taught you is Blackhorse standard."
He grinned, devil-may-care Uncle Dan again. "Life can't cover everything either, lad. Though it took me a while to figure that out myself."
Johnnie traversed the guns ten degrees, using the left-grip control, to swing them to the marked bearing of one of the distant islands. He then touched the right grip, bringing the sight picture back to direct.
For a moment, the hologram was an electronic image of the sea itself. Then the hydrofoil crested a swell and the sights centered on a blur of a gray slightly darker than that of the water. Johnnie dialed up the magnification to its full forty powers and thumbed in stabilization. The gun barrels rose automatically as L7521's bow slid into another kilometer-wide trough.
Just before the gunsight's direct viewpoint was covered by waves, the men in the gun tub saw something with jaws of yellow fangs lift above the vegetation and stare toward them. Nictitating membranes wiped sideways, dulling the eyes.
An image of sea water rose to fill the gunsight. Johnnie switched back to search mode.
He looked at his uncle, hunched below the tub's armor in the assistant's seat. The halo of spray from the steerable front foil soaked Dan as thoroughly as it did the younger man, but there was no sign of discomfort on his smiling face.
"You've been planning for . . . for years to do this, haven't you?" Johnnie said. "Bring me into the Blackhorse as soon as you could—twist the Senator's arm."
Dan shrugged. "The training programs? I wouldn't have forced you, lad. You wanted to learn, so you might as well learn the right way. Even the Senator agreed with that. Otherwise you might have run off and joined some jackleg outfit that'd get you killed—if you were lucky."
The implications of what he'd just heard spread across Johnnie's mind like the base of a slime mold, then burst into feculent words: "You don't think I'm good enough for a real company, Uncle Dan? You don't think I could get into the Blackhorse without you pulling strings?"
The older man shook his head. "Wrong wording," he said calmly, as though he were unaware of the shock and horror behind his nephew's flat statement.
"
You
don't think that any real company's going to enlist the son of A. Rolfe Gordon against the Senator's will, do you?" Dan explained. "War's a business, Johnnie. Admirals put their lives on the line, sure; but they're gambling on a lot more than the chance of getting killed. Nobody competent—nobody competent enough to command a successful company—would offend the most powerful politician on Venus."
"He may not be for long," Johnnie said in mingled regret and anger. "Heidigger and Carolina won't let him stay if they win."
"Even then no fleet is going to offend the Senator for nothing," Dan continued. "Nobody in the history of Venus has been able to do what your father's already managed—a free association of three domes, forced by the populace and against the will of the oligarchs who'd been running the show until then."
"But if he fails—" Johnnie said.
"If he fails
this time
," his uncle said, riding over the interjection, "there's still the chance he'll be back in power later. Politicians have long memories—and so do Admirals."
Dan focused on the sight picture, then frowned and rose from his seat to look over the armor. "Cover that," he ordered, pointing off the right bow. "Samuels is going to pass too close."
The sights went direct when Johnnie swung the guns with his right-hand control. The panoramic blur of land against sea became a huge mass to the left—probably the sub-continental Omphalos Sathanou, though that meant the hydrofoil's speed had been above the seventy knots Johnnie was guessing. To the right was an unnamed islet from which trailed a fur of water-brushing tree branches.
"All weapon stations, track right," Johnnie's earphones ordered in a voice that wasn't his uncle's.
The strait separating Omphalos from its minor satellite was a quarter mile broad, but only within a hundred feet of the islet was there a band of water which had enough current to clear it of mud and tannin. To the islet's right—south—clumps of reeds warned that the water there was dangerously shallow also.
Dan charged and aimed the automatic rifle which had been placed between his seat and the armored tub. "Bloody cowboy," he muttered.
"What is it?" Johnnie asked, trying to scan both the holographic image and the expanse of green/brown/corpse-finger white beyond it. "What am I looking for?"
