Quote from: The Rock Doctor on April 19, 2024, 05:00:35 PMThe machine guns would be problematic under international law (at least as we know it).

Eh, I don't think so. Given they're only capable of self defense against aircraft attack or direct boarding, they're basically useless in combat. Kind of like the usns mercy can house a phalanx mount.

Unlike the 130mm guns on the Aztec royal yacht that can be a hospital ship....but the Aztecs are under no false impression that the mayans would respect am unarmed hospital ship

Kaiser Kirk · April 19, 2024, 06:20:50 PM

The presumption is that history flowed similar in N7 to the 'Real World' and so our nations would have signed the treaties the 'Real World' nations did.

So the 1907 Hague convention governing Hospital ships should be in effect.
Finding the actual language prooved more difficult than expected, but wiki's summary works.

"The ship must not be used for any military purpose, or interfere with or hamper enemy combatant vessels."

I would not think those guns a threat to violate that provision.

Quote from: Jefgte on April 23, 2024, 09:59:20 AMAC4 need refit too

You can not add the Torpedo bulkheads under Refurbishment
"New armor decks, external belts, and external bulges for torpedo defense (not "torpedo bulkheads") can be added. Existing armor decks, external belts, or weapon armor can be replaced or removed (not increased)*. "
*torpedo bulkheads not included there.

Under Reconstruction, which has different pricing, which specifically includes moving around internal ship bulkheads you can.

"Internal belts can be replaced or removed. Torpedo Bulkheads can be added."

You could but why not just give the destroyers new DP guns as well?

QuoteYou could but why not just give the destroyers new DP guns as well?

It bothers me to throw 24 T2x120s from 1926 (0.48 BP) in the trash.
It's just a project, I'll test it with desT2x114DP.

Done 1730t with 3T2x114DP mlle 1932 => cost 1.73$ & 1.73BP

(cost with 3T2x120 mlle 1926 => 1.64$ & 1,64BP)
