Nice ships, would GC be willing to export them? No hurricanes in NS but there are probably volcanoes, earthquakes, and tsunamis.

They'd be operated by the Swiss Red Cross, for sure.

Nah, Blue Cross Blue Shield has better rates.  ;D

No exports until the first unit has completed trials, at the least.  The Colombians will want to make sure it's not a fatally flawed design before they start selling them.

After that, who knows?

Something tells me that Gran Columbia owes Romania for the idea....so Romania will be accepting one of the latter class, as compensation.  :D

Hmmm contimplates an Arrangement with the Habsburgs to deal with the Romanian Problem.  You just had an Explosion the Empire noticed that It had significant problems with going to one endless world crisis after another and the need for a fully set up hospital with modern capabilities was needed at all of them but that it took months to set one up in some building rebuilt for the purpose.

So we took the Standard Freighter design which the Empire has made into troops transports, and Oiler, and Tenders and modified the Troop Transport Version and created a Mobile Hospital.

The GC Design looks to be an outright improvement over my design being more efficent in its use of space and tonnage.

Romanian problem? Oh sh*t!

I know you guys have been waiting with bated breath for this one:  a new Colombian minesweeper.  Pic at the bottom.

With the coastal gunboat program winding down, attention is turning back to mine warfare, where the Colombians have a reasonable but not outstanding number of coastal vessels.  What is lacking is numbers, and vessels with the range to cross to Africa or operate on a prolonged basis.  The Rio Elqui class fills this role, while offering utility as a possible coastal escort.

The hull strength is high - representing a need for a reasonably large hull for high seas travel while the preference to avoid putting too much stuff inside that would affect the class' expendability.  The high hull strength will probably help in reducing damage associated with mine detonations nearby.

A minimum of fourteen vessels, built to civilian specifications, are planned.

It seems that the Romanian Naval Reports had some small effect.....

The Rock Doctor

Partly that and partly my own thinking.  Particularly recognizing that, as with a lot of my earlier torpedo-boats, my existing minesweepers had a low operating range.

As with the Pitalito class cutters, I'm building a few more than I necessarily need - allowing a reserve to be built up for my use in war or for sale to somebody else in a similar predicament.

P3D

I'd classify minesweeping equipment as "armor and armament", i.e. not buildable under civilian construction rules. Especially as about 10% of the displacement is set apart to increase hull strength/redundancy back up to naval standards, just to make sure they are 65% cheaper than military construction but without any disadvantage of "civilian standards".

The Rock Doctor

I wouldn't.  Nor have I since the rule was introduced.  Minesweeping gear isn't armament, nor armor. 

If you don't care for the "extra pumps", that's fine - I can just reduce misc. weight.

The Rock Doctor

I've adjusted the miscellaneous weight assignment for the new Golfo Tortugas class oilers.  Yes, that structure at the stern is what you think it is - only capable of mooring a Type 2 airship.

So it IS an oil derrick.

...yes, for those situations when it's easier to drill than go home and get more oil.
