How many do you think would be sufficient?

You're probably using patterns of 5 or 7 charges with enough for around ten attacks so 50-70.

I am sure a licence agreement can be made on the 40mm Bofors between Nordmark and Ireland.

I'd probably prefer the Bofors to the 2-pounder; from everything I've heard the Bofors 40 is the better gun.

Oh, it absolutely is, but then, it ought to be, it's about 20 years or more later in design.

The 2pdr though helps with commonality given the war-time role with the RN.

Vickers could offer the 0.661in HMG in a sextuple mount. Better rate of fire and only slightly inferior hitting power. It's what is replacing the RN 2pdrs.

Also the 2pdr offers a good anti-MTB capability.

I think the chance from hitting with the 0.661" is a lot better given the much higher muzzle velocity, but an 85g bullet against a 910g explosive shell? I can't remember the rate of fire being particularly good on the 0.661" either

Originally the BGM1 was supposed to come equipped with three 57mm AA guns. I figured that was a tad much, so I reduced them to 40mm AA guns.

I should note that the Connacht currently has 40mm guns of unknown origin - probably British 2-pounder guns or Atlantean 40mm guns, as I'm also using Atlantean 130mm DP. The .661cal is a possibility, but I prefer to stick with something in the 30mm-40mm range for my heavy AA.

Decisions, decisions...

Well, I'll build the first boat with the Bofors but keep my options open regarding arming them with 2pdrs. I'm solidly sticking to the 40mm for Shannon and the remaining destroyers, but I'll think about the .661.

For laying antisubmarine and torpedo defense nets, but also for maintaining buoys and the like. Should I build one?

Yes.

You can never have enough small auxillary ships like this to do the dirty work.

Why the CT armour? Seems a waste on a vessel like this.

Okay then. One Net-layer coming right up!

Um, habit for when I enter armour values...
