Seas of Venus(10)
Johnnie was rigid. He'd spent his life thus far training to be an officer in a mercenary fleet. His studies and simulations ranged from small arms to fleet fire control, from calisthenics to the logistical problems of feeding thousands of men with the usual assortment of dietary quirks, taboos, and allergies.
But he'd always been the son of Senator A. Rolfe Gordon. He'd never been treated like an object: like a side of meat of doubtful quality.
The passageway rose and fell; and rose. More seawater sloshed in. The sky was a hazy white like glowing iron, and the atmosphere weighed on Johnnie's shoulders like bags of wet sand.
"His name's Gordon?" Haynes said.
"That's right."
Haynes grimaced, then turned. "We'll discuss it with the Admiral," he muttered over his shoulder as he stomped aboard the waiting vessel.
L7521 was a torpedoboat. There were three long grooves on either side of her main hull, like the fullers of a knifeblade. For the hydrofoil's present duty as a high-speed ferry, those weapon stations were empty, but torpedoes could be fitted in a matter of minutes by trained crews in a carrier's arming bay.
A tub forward held a pair of .60-caliber rotary-breech machine-guns, while at the stern was a cage of six high-velocity ramjet penetrators which could punch a hole in anything lighter than the main-belt armor of a battleship. Several additional automatic weapons were clamped to L7521's railings, perhaps unofficially by crewmen who wanted to be able to shoot back with something, even if the rational part of their mind knew it was something useless.
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.
