New Colombian Ships for 1918

[The Rock Doctor]

This....




























...is a prototype torpedo-boat which employs technologies developed by Professor Mysterio.  For example, the hull is covered by a thin chemical layer which can change color when electricity is passed through it, thereby allowing the boat to be adapt its color to its surroundings.  The boat carries a 140mm electromagnetic railgun and three nuclear-tipped, rocket-propelled...

Oh, wait, that's 2018.  Sorry.  No new designs for the first half of 1918.  Come on back in the second half and there'll be something to see.

Ah, gotcha.

You got me...  ;D  I kept waiting and waiting for the drawing to appear.   ::)

The Espiritu Santo is the next step in Gran Colombian naval aviation, and is a logical continuation of experiments performed shoreside and aboard the old cruiser Casanare.  The ship is named for a Colombian frigate lost in the Second Colombian/Island Commonwealth War.

The airgroup will initially consist of two wheeled fighter planes and two scouting floatplanes.  The fighters are stored in a small hold under the taking-off ramp, and would be lifted up to the ramp via crane.  The floatplanes are stored in a modest hanger aft, serviced with a single crane aft.  It is anticipated that a variant of the floatplane with folding wings will be operational by the time the ship is actually completed and in service, allowing the floatplane capacity to increase to four.

It is envisaged that the ship would primarily support battleline operations - using the floatplanes for spotting and scouting, and using the fighters (if necessary) to intercept enemy units attempting the same.   At such time as Colombian capital ships begin shipping aircraft of their own, she might also function as a tender to them.

The ship is built on a cruiser-like hull.  The ship is faster than current and expected battleline speeds in order to allow for station keeping and aircraft operations.  She is armored against light cruiser gunfire, although given her place on the disengaged side of the battleline, it is unlikely she would actually see action.  Her armament is minimal, but she is expected to have an escort of some sort while operating.

One unit will be laid down in July 1918; a second unit is under consideration for 1919.

The fighters can't land. Or are we seeing a continuation of the kamakazie?

[Sachmle]

The fighters can't land. Or are we seeing a continuation of the kamakazie?

My guess is that IF near friendly ground that the fighters land there, if not they ditch in the ocean and the pilots are picked up. All told he's out $0.004 for the planes.

[TexanCowboy]

Yes, with such profilificant loss of money, is there any question why the CSA would win a war?  ;D As a result, the CSA is currently accepting all surrenders.  ;D

[The Rock Doctor]

Sam's correct - one of those minor problems associated with early carrier designs.

[Jefgte]

Thats a good ship, she could be really useful.

did you test just 120m lenght  ?


Jef

[The Rock Doctor]

I didn't try it, but I'm sure I could trim the length if I wanted to.  Just not sure I really need to, though.  I've got a fair bit of infrastructure that can support the ship.

[Jefgte]

It's a shame, this could be useful to repair the ship on site, in operation, in case of conflict for example Philipppines in SW 120m.

Two new attack transports will be laid down in 2/1918.  They are basically a continuation of the previous run of eight, but with newer engines.  The reduced machinery weight allows for a bit of additional superstructure, which will go towards command and control facilities for landing ops.  The two new units will provide the Colombians with capacity to lift two 5,000 brigades.
