Two competing solutions had been proposed. One was to reinforce the tubes by winding them in thick cocoons of steel wire, which just happened to be available in significant quantities once the spools of steel cable had been discovered at the coal mine. Unlaying the cables by hand to separate them into individual strands of steel wire had been a laborious and manpower-intensive task, but once the decision to support the ironclad project had been taken, the manpower had been made available.
The second solution had been to cast bronze reinforcements around the tubes. In some ways, that was a simpler approach. It would result in somewhat heavier guns, but the technology to accomplish it was already available to the 17 th -century's metalworking industry. The finished guns would be somewhat heavier, and the tubes themselves might warp slightly in the casting process, but Davis doubted very much that the warping would present any insoluble difficulties. They were planning to do a final bore in all the gun tubes anyway, in order to bring them to a uniform size.
"The theory is that until we've got the on-site ability to do the casting here, they're going to have to ship the finished guns to us overland. The casting teams are pretty heavily committed to the field artillery and carronade projects right now, so coupled with the lighter weight for shipping considerations they decided to go with wire."
"As long as they make the delivery schedule, I don't really care which approach we use," Simpson observed.
"Yeah," Eddie agreed, but his expression was pouting. "I still say we could have produced a breech-loading design, though. Our rate of fire is going to suck."
"That decision has been made, Lieutenant," Simpson observed a bit coolly. Then he relented just a touch. "I'd obviously prefer breechloaders, myself," he said. "But the Allocations Committee was right. We don't have the resources to do everything we need to do, and muzzleloaders will do the job for us. Especially with the hydraulic recoil systems."
He shrugged, and while no one could have called Eddie's nod cheerful, there was no real disagreement in it.
"At least they'll recoil inboard so they can be reloaded under armor," he sighed.
"Especially in light of your suggestion to operate the port shutters with the same recoil system," Simpson agreed. Nat was aware that Eddie still considered himself an unabashed partisan of the Stearns administration and so, by definition, a natural enemy where John Chandler Simpson was concerned. Despite that, he noted a flicker of pleasure in the redhead's gray eyes at Simpson's acknowledgment of the youngster's contribution. One of his many contributions, to be sure-but Nat was still somewhat surprised that Simpson himself could recognize it, much less be willing to acknowledge it openly.
As he had sometimes before, Nat found himself wondering if the elder Simpson had found the personal rupture with his son Tom far more painful than he ever indicated in public. If so, it might be that in some odd way John Simpson was finding in brash young Eddie Cantrell-as well as his friend Larry Wild-something in the way of surrogate sons.
It was hard to know. Whatever John Simpson's other talents, "personal sensitivity" was very far down the list. Nat shook his head slightly and returned his concentration to the matter at hand.
The gun mount design Davis and Ollie Reardon had finally come up with was a far cry from anything the 21 st century would have accepted, but it ought to be sufficient for their present purposes. It would permit the guns to recoil completely, then lock them there, with the muzzles well inboard while they were sponged out and reloaded, until the release lever was tripped and the hydraulic cylinders ran them back to battery. By adopting Eddie's suggestion and using top-opening armored shutters for the gun ports and an articulated rod between each shutter and the carriage of the gun it served, the same hydraulics would open and close the gun ports automatically as the weapon was served.
"What about the carronades for the wing mounts and the timberclads?" Simpson asked.
"They're coming along on schedule," Davis assured him. "And the team at Luebeck says that they'll be ready to begin casting Gustav's carronades on-site within another four to five weeks. We just got a radio message from them yesterday."
"As long as they don't distract resources from our project," Simpson grumbled sourly. "That monster Gustav demanded has already eaten up enough effort."
"I don't guess we should've been surprised," Eddie observed with a grin. "I did some research on seventeenth and eighteenth century navies for a war game a couple of years before the Ring of Fire, and it was only a few years ago Gustav built this really big galleon. Supposed to be the biggest and baddest warship in the entire Baltic. Named it for the Vasa dynasty."
"Really?" Davis looked at him and raised an eyebrow. "Should I assume from your expression that it was a less than completely successful design?"
"You could say that," Eddie chuckled. "Sucker sank right there in harbor. Seems they hadn't gotten the stability calculations just right."
"Wonderful," Simpson snorted. "Not exactly the best recommendation for his latest project, is it?"
"Oh, I expect they'll get it closer to right this time… sir." Eddie grinned again. "The king's naval architects just about ate my copies of Chapelle's books on American sailing ship designs. They don't show any ironclads, but the sloop of war design they settled on should carry the armor no sweat. Especially with the reduction in the weight of guns."
"I don't really doubt that the design is workable, Lieutenant," Simpson said. "Practical, now… That's something else again. It's a sailing ship. That means they're still going to have to have men on deck to trim the sails, which seems to me to leave a teeny-tiny chink in their protection."
"Guess so, at that," Eddie allowed. "Of course, the armored bulwarks oughta help some, even there."
"Some," Simpson acknowledged. "In the meantime, though, we're diverting the effort to build a real rolling mill at Luebeck."
"Maybe so," Davis said, "but it's going to be turning out iron, not steel. And the individual plates aren't going to be all that much bigger than ours, anyway." He grinned at Simpson. "Frankly, I'm just as happy to let him play with his own design while we get on with building ours."
"You may have a point," Simpson replied. He let his chair rock back and forth a few times while he considered what Eddie and Davis had reported. At least it didn't sound as if there'd been any more slippage in the construction schedule. He considered-again-suggesting that the timberclads be given a somewhat higher priority. True, they were going to be much smaller, armed only with relatively short-ranged carronades and protected only by extra thick, heavy timber "armor." In addition, they were going to be powered by paddle wheels between their catamaran hulls, and their power plants would be steam-driven. In every way that counted, they were going to be cruder, less capable designs. But they were also going to be available in greater numbers, and they were going to be shallower draft than the ironclads, even with the bigger ships' trim tanks.
He had a nagging suspicion that he ought to be pressing for their more rapid completion. After all, all they really needed was to be just good enough to do the job, not the best design that could possibly be produced. Surely he'd seen enough unhappy demonstrations during his original navy days of what happened when the service insisted on building in every possible bell and whistle!
He told his suspicion-again-to shut up. No doubt there was something to it, but there was also something to be said for building at least a few really capable units for the timberclads to back up. And if there was an element of the empire building Stearns was so contemptuous of (even while he was busy building his own little political empire), then so be it.
