What's the estimated cost of these projects?

Ithekro · April 14, 2008, 10:00:08 AM

4,000 tons of materials (engines, guns, fire control, extra) and about $7.66 each (a cent more for Eomer due to the flagship facility).

I basically need to keep them servicable and viable combatants until the mid-20s when construction should have caught up at last with Rohan's naval policies.

Jefgte · April 14, 2008, 10:00:45 AM

What did you change for the rebuilt?

Just the engines?

Jef ;)

Ithekro · April 14, 2008, 10:06:52 AM

Engines (1909 type plus better), more fuel storage (10% oil fired boilers), new guns (1902 models), fire control, and bulges for stability. More or less to match the conversions on the Theodens done in 1910 only with added fire control and slightly greater speed. Only Elfwine is getting her "B" turret raised to make it superfire, as the other two had that done already (based cost of Elfwine conversion, not Brytta conversion, though they should be about the same).

These all cost a little more than the Theoden rebuilds since they are all larger and have both fire control, larger engines, and bugles added where the Theodens did not (they have provisions for fire control however and may get that after these three ships are finished).

After these three ships are done and the two Theodens have fire control, the five pre-Arcadia will be nearly identical in specifications and capabilities and hopefully viable as warships for at least another ten years (or to maybe 1925).

The Rock Doctor · April 14, 2008, 10:13:28 AM

What are Rohan's naval policies? It seems like a lot of effort for ships of their age...

Ithekro · April 14, 2008, 10:27:06 AM

Numbers. With the addition of San Francisco and "Chile" the Mark has more ocean to cover and wishs to have at least two battleships at each base if possible. With there now being eight main naval bases, that means the Mark needs at least 16 active battleships (not counting battlecruisers but including the Arcadias even though half the navy wants to class them as battlecrusiers). With these ships in refit and four under construction, the fleet has eight battleships in service. Once completed (and with an additional two battleships laid down every other year) it will still take at least until 1918 before the Mark has 16 viable battleship in the fleet, and some will be in refit by then, so to keep the fleet stable at 16, there needs to be a cushion to allow ships to be in refit. Therefore the fleet actually needs to have at least 18 battleships in service to allow for refits, thus the fleet plan will not be viable until around 1920, when the Theoden will be near the end of their service life. Thus the fleet will need to have to have enough ships in service or nearly completed by the mid-1920s for when these five pre-Arcadias leave service and be getting ready to replace the two Arcadias and the two Freawines by the early 1930s while still maintaining about an 18 ship battleship force.

The Rock Doctor · April 14, 2008, 10:34:16 AM

This seems like a very ambitious goal. Does the possession in southern Chile, for instance, warrant two capital ships?

Ithekro · April 14, 2008, 10:42:41 AM

Probably not, but planner can't say what will happen, only what they can plan on. Chile may only warrent one battleship at best, but the Caribbean bases may actually require more that two per base.

Borys · April 14, 2008, 10:57:08 AM

Ahoj!
IMO Araukania merits one rusty PC.
There is nothing of value there. Hand out 50,000 rifles to the locals and you're safe. Especially as the local alpacas are famed for their ill tempers and foul spit ...
Sponsoring articles in the Navalism equivalent of the National Geographic that local ladies dance to the stacatto of castanietas made from shriveled nuts of their brothers' slain foes will not hurt either ...

...and some of us is happy if we manage to get one capital ship per two bases...

Sachmle · April 14, 2008, 11:05:44 AM

True. And some of us have to count ACs as capital ships to break even.
