While the stirring discussion over my "Aww Frigate about it"s will die down Schooner or later. I bet it's barque is worse than it's bite, wait some of those words might be puns, oh well, just a sloop of the tongue.

Anyhow, ever since Latvia came up, I've been toying with the Belgians seeking an expeditionary fleet on the theory that when the League of Nations called, if they are who can respond, that will raise their political power and visibility, as well as reinforce their martial nature. To the Walloon political class that's an attractive use for a navy.

So, I'm toying with light cruisers mounting not the 12x6" but 8x6" in twin quads+ 4x 240mm turreted howitzers for shore/riverine bombardment, dock ships with parasite craft for littoral work, hospital ships, helicopter/autogyro hosting fighter carriers...fun stuff.

In the mean time here's a pretty simple gunboat that can be deployed overseas and operate independently.

Gunboat? Don't you mean "Colonial Aviso"?

no, it's a boat. It has guns. and I don't speak the romance languages, I just mangle German a little bit.

This is the Brailmont concept - an Expeditionary Cruiser.
I might consider adding some length and trying to bring the speed up. I'd like to manage 26kts to match King Albert, but I can't figure out what the point would be.

However it illustrates the basic idea with the howizter turrets mixed with the dual-twin quads. All in a package the Belgians might be able to field.

Pair this with a Fighter carrier, and a couple amphibious transports, and the Belgians could seize and control a beachead around a port, use that for operations against rabble, be it Latvia, Pakistan, Peru, Hamburg, all the usual places.

2nd Battery Shell weight too heavy

A Belgian gunfire support vessel.

Designed to support amphibious operations and secure coastal beachheads, she has a broad, shallow draft hull to allow forays up rivers as needed. The provision of 4 propellers and electric drives helps ensure additional manueverability in reverse.

A & Y mounts are Quad 6" naval rifles, intended to silence any coastal batteries and deal with any small vessels encountered. The Mk XXII IQuad turrets are simmed as 20% overarmored to account for a dual-twin size and central partition. The 6" Guns fire a 50kg shell to 22,400m.

B & X mounts are dual 240mmL35 Howitzers, firing a 163.3kg shell to 23,030m (12.4nm). However the abilities of a howitzers shine closer in when plunging fire can be used to dig out enemy emplacements and engage targets on the reverse slope of hills, where the flatter firing 6" would have difficulty engaging.

7.14" gun = 240mm / 35, 23030m 163.3kg : 23030kg

The large magazine size allows for standard 150rpg Training/Parachute/AP/SAP (anti-concrete for 240mm) loadout to be carried, while the remaining 250rpg are simple HE.

The Brialmont has the ability to act as a escort cruiser do to the 8x6", and as a larger vessel is more suited to an oceanic role.

This one was more an exploration of the minimum size for the expeditionary cruiser role. Small, still capable of transiting to the expeditionary point, large magazines, large howitzers. So DP mounts to fend off destroyers/MTBs as needed. Fairly shallow draft to go up estuaries.

Seakeeping and steadiness are extremely high as I added a deck level to allow oceanic transit, but her speeds still very low.

I think the smaller ship is probably the better option. The larger ship seems like it's trying to be too many things to too many people. Though you make note of the possibility of operating on rivers, I don't think there are many rivers capable of a ship of those large dimensions - not merely draft, but beam and length. Aside from the very lowest reaches of the Danube, probably a bit of the Yangtze, and a few other major rivers.

Are the 4.7" guns intended to be all in single mounts?

When I'm speaking of riverine work, it would need to be pretty major rivers. However that would include the Scheldt and Rhine and Meuse - or any such large river in the world. From Google earth there looks to be a canal which looks to be as much as 50m+ wide all the way up to Liege. Several sections exceed 100m, and there are some junctions that with shore assistance you could (this sounds silly) 3-point turn the ship. ...oh rats thought to actually google the thing, it's the Albert Canal, depth 3.4m.

....still that gives me a target dimension for the next efforts....

As for these two, I realized there'd be rivers they could get up only a short distance, but even a couple miles helps. Then going down, one advantage of electric drive is full power in reverse, and enchanced manuevering by altering propeller rotation rates. So as long as there is a little room for wandering, they should be able to move.

I'm rather certain either of those ships lending fire support would make the opposition very upset very fast. 360 pound HE shells- and Howitzers have a higher % of filler... figure up to 12-16 rounds a minute.

The 4.7" are supposed to be twins, grrr. Didn't notice that. For that matter so is the main battery.

The criticism of the Brailmont trying to do to much is accurate. I'm not sure that from the way I role play the Belgians that's a disqualification, the ships are supposed to achieve political goals. For example, they didn't want to pay for a Battleship, but wanted something that could beat treaty cruisers for prestige purposes, so they got the plans for the King Albert from the Australians. Then, to appease the Walloon representatives who didn't like paying for ships, they demanded it burn Belgian coal, while sporting French AA weapons and Australian large bore guns.

I think the Belgian budgetary process will have the biggest say on which gets built.

Well its all novel stuff and WW has lacked novel ships for some time.

It's one reason I didn't just merge the Belgians with the Dutch and pick up 5 free factories. The Dutch have always been in this mode of arming to the teeth as part of preparing for a SATSUMA war, something that only recently has changed. The Belgians- they can have whacko goals just so long as I can come up with the political justification.

So anyhow, after doing some research on the Prince Albert Canal, it's 3.4m-4m deep and I think 60m+ wide. Further, it has some intersections where a larger ship could turn.

Lastly, I'll take the wild leap that a ship that can navigate that can navigate most Belgian/Dutch canals "If I can make it there, I can make it anywhere, NL, NL !" etc etc

Or at least enough to make them usable.

For the Belgians the key consideration would be able to move rather heavy artillery to strategic points- probably pre-surveyed. From that location quick and accurate fire could be taken against enemy locations, captured infrastructure, etc. In the worse case- and this is important- bridges that need to be taken down could be shelled and either destroyed or interdicted.

So, I bring you the Namur.
Liege is a close copy of Erie, and Empress Charlotte is a modified Vanamoinian, this is expanded from a Dutch OTL Gruno....but I was really not sure how much beam I'd need to mount a single 240mm howitzer. So I stuck it in the middle of the ship where the beam is as stated, not the ends where it's less.

The OTL Dutch coast defense vessels managed single 240mm guns in turrets at ends of ships on 15.1m, and a twin 21cm turret on 14.3m. Then toss in a half-century in metallurgy advances and design improvements, and I figure I'm in the ballpark.

The Gunboat has 2 unique features
1) The 240mm L35 Howitzer firing a 360lb (163.3kg) shell up to 14.3 miles (23,030m).
2) An spherical rangefinder/radar mount on a mast, armored against splinters. This is simulated by a 6.54 superimposed gun with 0 ammo weight, armored.

The OA length of the 240L35 Howizter (7.14") is roughly 8.4m long, with the turret about 5m in diameter, for an overal length increase of about 12m over a Gruno Class gunboat of the Dutch.

Where the Gruno featured waist 12cm guns, the Belgians placed Quad 37mm in Wirblewind tyle shielded quad mounts. Due to the additional 12m of length, a second set of Quads was placed. A series of twin 20mm guns are studded along the infrastructure.

Armor has a splinter belt from freeboard down 1 deck level, then the main belt descends to 1m below sea level.
