Well, the simplest idea is not to propel it at all.

Meet the "projectile torpedo":

Basically, it is elongated submarine shell, fired from the tube by small powder charge. It is balanced such way that it would continue its trajectory underwater, as long as it have initial velocity, or until it would hit a ship. The range is limited, of course - about 40-50 meters - but since Charisian ships have no quick-firing guns less than 6-inch, the limited range is of no concern; small torpedo boat would always get through.

As I said compressed air is the first step. You idea will work in very tight places. Say the channels to Gorath Harbor or the Kaudzuh Narrows. Odds are good that each of your PT Boat will be destroyed before they get their torp off. Still, it does have applications. Extending their ranges will only expand their applications.

Also, the need for speed while the torps are still short legged may well expedite the development of IC engines. A good marine diesel powered PT boat will give manually aimed lighter guns fits on their approach runs. Quick firing lighter guns using power assist to aim will be muchh more effective.

Er, it is not my idea; it is historical weapon, used by Russian and American navies in late XIX century.

They are NOT PT boats; they are torpedo boats. Like this:

And how exactly they would be destroyed? Charisian ships literally have nothing that could successfully engage rushing torpedo boats. Hotchkiss guns were installed on the battleships & cruisers of late XIX century for a reason)

...There could be no IC engines on Safehold now. Rakurai array, do you remember? And I'm talking about torpedo boats, not patrol torpedo boats or torpedo motorboats.

Early torpedo boats did not go much faster than Thunderer. They were just smaller with a much smaller turn radius. Having a diesel engine, which doesn't need electricity, allows to the PT Boat or motorized torpedo boat to double that speed.

A destroyer screen is easily as fast as steam TBs, so breaking that screen to attack the heavies will be very hard. A greater speed differential is easier to achieve with IC engines.

Um, you really think Thunderer is going to be traveling around by herself?

When the ICN decides they want to visit, and destroy, your port, what is your defense? If your land-based forts can't withstand her guns, and can't hurt her, you're toast

Irrelevant of her classification, she seems to be underarmed quite a bit.


runsforcelery wrote:Indeed she is. Now why, I wonder, would the ICN have built a ship not quite as nasty as they could have?

Most of the improvements here are detail: better guns with better propellant and faster rate of fire, better arrangement of the armament, hydraulically powered hoists, improved machinery, better distribution of armor. etc. She's also carrying a lot of freeboard because of the weather conditions and sea states in which she's expected to operate, and the casemates are actually in the superstructure and stepped back from the side to reduce blast and spray interference and prevent them from being washed out at anything like normal speeds or "Atlantic" conditions.

Now, there are more reasons than one to go to a dreadnought-style armament. None of those reasons are really in play at this point, although the Inner Circle has already drawn up plans for how to approach the design when the time does come. This is essentially a transition design --- a tech demonstrator to get other navies thinking about proper turret mounts, powered turret machinery, and the other features of a workable design (including how much industrial capacity it will take to build the things).


I can think of several reasons for building something like this. Fighting battles is not one of them.

The historical problems with building a ship about the same size as a battleship, with the same main battery as a battleship, and at about the same cost as a battleship, is that sooner or later it ends up being used as a battleship. Heligoland Bight and Falkland are classic BC actions, but Jutland (and Denmark straight) both saw BCs used as fleet units with tragic results.

Second, they didn't last very long as a concept. The 'fast battleship' concept of the '30s effectively combined the advantages of the BB/BC concepts, but as early as 1905 the proposed British X4 design was for a capital ship with Dreadnought-levels of armor with the 25-knot speed of the Invincible class. And really on the RN actually used them (and only one survived) WWII, the USN modifying the two under construction into aircraft carriers, and the IJN rebuilding the Kongo-class into fast battleships.

Now, as for why the Charisian Royal Navy would build them? First, it's a tech demonstrator; second, it's a tech demonstrator (that is, it demonstrates the tech, and does so in such a way it gets likely opponents to build a ship that will shortly be obsolete or likely to be misused, see above).

Third, it becomes a floating example of Charisian power (much the same role HMS Hood had during the 20s and 30s.)

Fourth, it keeps necessary industries in Charis in business. It's easier (so long as you have the money) to keep building guns than it is to get gun manufacturing going again after a ten-year (or whatever) hiatus.

Fifth, it serves as a floating school. There are three KHVII, and what, a double handful of Cities? More of the River- and Delthak-classes, of course. But the overwhelming number of ships in the CRN post-Jihad are still sail-powered. Having additional hulls to train crews in powered-ships would be useful.

Six, it's 'good enough' to turn any sailing ships that fall in with it into very expensive kindling. That includes any armored sailing ships that someone *cough*Dohlar*cough* might produce.

Seventh, it clearly demonstrates a 'native' evolution in design both to Charis' own people as well as anyone who might be wanting to do them a mischief. This is important as it protects the Inner Circle from 'provable' accusations of demon- and Proctor-worship. (won't stop anyone from banding those about, of course, but so long as Father Paityr says it's 'okay'...)

Why not? In previous war, Charisians threw battleships in actions without any escorts. (And I knew that RFC tend to disregard the need of escorts, coastal & convoy protection ships ;) )

I don't understand this comment when there are plenty of examples of these in RFC's books.

Examples, yes. But not much use. Of course it's only my IMHO - and I clearly not always right - but for me it seems that RFC tend to underestimate the value of light units less than sea-capable destroyer analogue. I.e. patrol crafts, escort ships, gunboats, ect. Both in Honorverse and in Safehold, warring fleets tended to pump out as much capital ship as possible, and basically do not build anything functionally smaller than light cruiser.

No offense.

I think he foreshadowed the advantage of lighter craft with the RDN's success over the ICN. All of which came under Mediteranean conditions in the Gulf of Dohlar. The RDN's most lopsided loss came in Atlantic conditions in OAR.

Lighter, faster and more short legged craft will have an advantage in the Gulf over the ICN's need to project power over great distances. That need argues for heavier, more individually capable ships. Having bases scattered around the globe creates other demands for resources to offset being freed from relying totally on big, nasty battlewagons and long ranged cruisers. It's all a metter of resource allocation and what will best achieve the long term goals.

Having ships less capable of offensive firepower but highlight other technical features that are adaptable for civilian uses will appear more attainable and desireable for the other Safehold nations. It helps that these ships are also less well defended with vulnerablities that may be taken advantage of by things like TBs. Charis has to create these first few generations of warships with vulnerbalities to foster innovation by their competitors. If they don't, they disincent other nations from even trying to innovate.

So the response from Dohlar will very likely be to create many small, fast attack craft to overwhelm the under gunned battle wagon. These small craft are less useful for force projection over any sort of distance. However, most of those competitor nations primarily use the Gulf of Dohlar and so have no real need to project force over huge distances. Those small craft will be useful in defending against the vulnerable ICN heavies.
