They were lethal and efficient within their limitations; but those limitations made railguns primarily defensive tools, the shield of the battleships slashing at one another with the sword of their big guns.
There was another enclosed companionway leading up the exterior of the shelter deck superstructure to the bridge whose wings flared out beyond the line of its supports. Sal opened the hatch, then paused.
"Those," he said pointing to the railguns, "would have to be ungodly lucky to hit us in the ass-slappers."
They can hit a plunging shell, Johnnie thought, so they could damn well hit a skimmer if they wanted to waste the ammunition.
"And those," Sal went on, indicating a turret holding twin guns of the dreadnought's secondary armament, "the five-point-two-fives, they couldn't hit us if they had angels riding on every shell. Sure you don't want to transfer to us and ride ass-slappers, Johnnie? Safest job in the fleet, I tell you!"
"Aw, my uncle's a big-ship man," Johnnie lied with a grin as the two of them began echoing up the slotted treads of the companionway.
The skimmers weren't safe even when nobody was shooting at them. The bow wave of a friendly vessel—or the back of a surfacing fish—could either of them flip one of the little pumpkinseeds in the air like a thumbed coin. If that happened and the ass-slapper's own speed didn't kill the crew, the life teeming in the sea would finish the job in minutes if not seconds.
No, skimmers were romantic—and now that Johnnie had seen a dreadnought close up, he realized that the big ships surely were not. But battles were decided by the smashing authority of the dreadnoughts' main guns. Everything else, necessary though it might be to a successful outcome, was secondary to big-gun salvoes.
Everything but perhaps strategy was secondary to the big guns. Uncle Dan hadn't risen to his present position simply because he knew how to press a firing switch.
Johnnie had thought he was in good shape . . . and he was, for the purposes for which he'd trained. He hadn't been running up and down staircases on the planet's surface, though. His legs were so rubbery that he used his grip on the handrail to boost him up the last few steps to the hatch marked: "Bridge/Access Controlled."
"It's closed," Sal explained as he touched the switch, "because they've got the air-conditioning on inside. Scratch a big-ship man," he added, smiling to take the sting out of the words, "and you find a pussy."
A puff of cool air spilled down the companionway as the immensely thick hatch cycled open. It revived Johnnie like a bucket of cold water. He wasn't sure that the constant change from Venus-ambient to artificially-comfortable wasn't a lot less healthy than acclimating to the natural temperature—
But for now it sure felt good.
There were six men already present on the bridge. One of them was the senior lieutenant acting as Officer of the Day. The armored shutters were raised so that Johnnie could look out at the harbor area through glazed slits; but it seemed to him that the banks of displays, both flat-screen and holographic, gave a better view.
The OOD was talking to a control console. He looked up and frowned as the ensigns entered the bridge. "Roger," he said as his right hand threw switches. "Roger. Out."
"Just showing a visitor the Holy Trinity, sir," Sal said cheerfully, before the lieutenant could ask.
"Well, keep out of the way, will you?" the senior officer said sourly. "Base wants us to help with the yard work."
"Turret Eye-Eye live, sir," said a technician at another console.
"Bring it to seventeen degrees until they give us final corrections," the OOD instructed. "They'll pipe them in, they say. And load with incendiaries."
"That's the forward starboard five-point-two-five turret," Sal explained, though Johnnie had already figured out the reference. "There's four secondary turrets on either side amidships."
"Want me to ready Beta Battery, sir?" called a junior lieutenant from the far wing of the bridge.
"No, I do not want you to light the main drives, Janos," the OOD snapped. "Besides, for what they want, the secondaries'll do a better job than the railguns would."
There was a horrible squeal of dragging metal, through the fabric of the ship as well as the air. The turret's superconducting gimbals had not come up to full power before the mechanism started to turn.
"That ought to be repaired!" the OOD said.
"It has been, sir," replied the man at the gunnery board. "That mount, it always does that. I think it's the power connections to—"
"Mark!" said the OOD.
A pattern of lines overlay a map display on the active gunnery screen. They shifted suddenly without any action by the tech at the console. The ship vibrated as gears drove Turret II a few seconds of fine adjustment.
