Enewald - no submarines because no electrical gear, or telephones, or whatever you build subs out of in Vic:Rev. Patience - the submarines are coming.
The submarines are coming...
Stuyvesant - Yes, Captain Horne is an invented character. He is sort of the anti-Mahan since he avoids the historical and geographical forces to focus on what type of ship the Royal Navy should build. Alfred Thayer Mahan felt that strategic principles and geography were little affected by technology and didn't much care for the new steam-and-steel fleet.
In Victoria, the latest ship class usually has a big advantage. Ironclads kill wooden ships and raiders, protected cruisers shred ironclads, pre-dreadnought battleships decisively trump protected cruisers. Of course the usual forces of morale and organization also weigh heavily.
My US is determined not to provoke Britain, but I don't like them beating up on Mexico either. Whether or not Britain wants to be
my adversary is another question; at this point I'm just rambling along and hoping not.
merrick - sometimes the AI is hard to beat exactly because it does such goofy things. Even a stopped clock is right twice a day.
To challenge the Royal Navy you have to mount a challenge and be seen as a challenger. Had Beresford kept the confidence of King Edward VII and been in charge instead of Fisher, the Royal Navy would have gone only reluctantly into the battleship age. Had Wilhelm II been less of a publicity-loving, tone-deaf chowderhead, Tirpitz might have gotten into better striking range before Britain woke up. So it goes - the 'ifs' accumulate.
The British don't get the pre-dreadnought tech until around 1889 or 1890. The US gets it in 1883 or so. Given that the game says the US is building pre-dreadnoughts, what could those be?
Devastation and ships like her - capital ships recognizable as battleships and not central-battery or sail-equipped ironclads. I know that isn't a particularly good place to draw the line and it certainly isn't where I would choose, but - the game says the US is building battleships in 1883, and
Devastation is just about the best tech available. As you point out there was a lot of experimentation and hunting around before the
Royal Sovereigns pretty much settled the question. The US has a signal advantage in having a man who already knows the 'best' solutions.
HMS
Captain could almost be the subject of a discussion all by herself. Captain Cowper Coles designed one of the world's best turrets and camapigned endlessly to get the Royal Navy to build ships to his design, with heavy guns in his turrets, heavy armor, fast speed under steam, very tall masts and spars for high speed under sail, and a low freeboard. He and his supporters finally wore the Admiralty down and he got permission to build a ship to his own design. The end result wasn't bad; she could have had a long and happy life were it not for three things. The Admiralty refused to take any responsibility for her construction or provide any more than a very general oversight. Coles wasn't a trained naval architect. And the builders mis-calculated the weights - when launched she was several feet farther down in the water than designed. The Admiralty refused to accept the ship unless Coles signed off on it, which he finally did. The problem is that a ship's ability to right itself from a roll is partly dependent on the height of its side. Once
Captain heeled more than (I think) 25 degrees or so the righting force began decreasing and she just kept going over. That happened in a storm; almost everyone (including Coles) perished.
Iain Wilson - merrick knows his stuff, and I'm a complete navy tech-geek, so when the two of us get going it rapidly degenerates into jargon. Very meaningful, well-informed and interesting jargon, however.
Alfredian - you're probably aware of Robert K Massie's 'Dreadnought', which is both a detailed history and a love-song to an age that was busy trying to kill itself. The US/USSR naval rivalry of 1950 on is another example of a shipbuilding race.
J. Passepartout - well, in Vicky the AI tends to build only the newest and best type until another newer and better comes along. And barring losing ship in a war it never scraps the old ones.
Fulcrumvale - relations between the US and UK went from pretty fair to awfully bad several times from 1850-1915 and it is possible the two countries could have gone to war at a couple of points (Hawaii and Samoa being two). But Britain was a firm friend during the Spanish-American War and of course WWI changed the dynamic and set the tone for the Atlantic friendship we still have.
To all - I rewrote the requirements, specs, cost and maintenance cost and construction times for all the ship classes past ironclads. In short they are much more expensive, require more types of materials and have different characteristics (subs have high shock attack while carriers have very high scouting values).
In our history, the advent of the quick-firing gun and the automobile (self-moving) torpedo led to the French declaration of a rival school of naval warfare, the
jeune ecole. Unlike the Royal Navy, which put its weight into battleships for blockading ports, the French would build large numbers of torpedo boats to fight a close blockade and cruisers for commerce raiding. Like the later Soviet bomber/missile/submarine challenge to US carrier groups, the
jeune ecole was supposed to bypass the necessity for an expensive battle fleet. Like Soviet doctrine, the
jeune ecole was never tested. If history is any guide it failed, for commerce raiding depends on open ports or on ships able to evade a blockade. Like the raiders of the Napoleonic wars a
jeune ecole campaign against commerce would have been painful for Britain, but probably not enough to be decisive. Submarines would change the equation because of their ability to avoid detection...
In the history of 'Providence', the
jeune ecole has triumphed in Britain, where the Royal Navy is busily building light ships for commerce protection. As several of you have pointed out, the lack of any serious challenger has allowed the Royal Navy to get by on very small budgets. It seems likely to me that the best and brightest officers would have left the Navy or given up and become drones, so if anything the Royal Navy of 'Providence' is even more reactionary and hide-bound than it was in real life.
As to the American answer,
Devastation dates from 1873 and the
Admiral class from 1887. The revolutionary
Duilio and
Dandololikewise date from 1880. With a little creative jiggering we can have 'battleships' displacing 10,000 tons with modest freeboard (no masts or sails) making 15 knots under steam alone, with 4-12" breech-loading rifles in two turrets or barbettes and boasting 14-16" armor. Add in a battry of 6 to 8 6" quick-firing guns and these
look like battleships. Their guns and armor would be sufficient to blow a protected cruiser out of the water.
Essential here is that we assume the Royal Navy made a complacent, budget-bound decision to put commerce and colonies over battle fleets. They believe that two (or four) British protected cruisers could out-fight a battleship. In such a closed-in, self-centered, reactionary service no British admiral would assume otherwise. The big American ships would be derided as wasteful, inefficient freaks.
For those who don't know, a
turret is a metal cylinder, usually several decks high, containing guns. The entire structure rotates. A
barbette is an armored, non-rotating cylinder set several decks deep into the hull. The guns are usually on a turntable and poke over the lip at the top. Later an armored gunhouse covered the turntable and this was also called a turret.
