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
