You're reminding me that my MS-1 class is ancient and in need of being replaced. Sigh.

The Rock Doctor · February 18, 2023, 07:58:31 AM

It's a type I've relegated to auto-building one a turn and just updating the design once in a while.

TacCovert4 · February 18, 2023, 01:10:27 PM

If I do something it'll probably be a combination asw and minesweeper.

The only thing I would look at is the AA suite. It's the 1920s, one AA gun is getting pretty paltry, especially when the MGs are only a pair of rifle caliber guns.

There are no real aircraft carriers yet and no torpedo squadrons and dive bombers.
Byzantium will develop more consistent AA weapons in a few years.
Note that all Byzantine ships also have 47/50cal QF Vickers against MTBs and Aircraft.
7,7 MG are for close protection in harbors or very near coasts.

True, and Byzantium hasn't had a bunch of recent air combat to inspire a push to have more AA. The Aztec push away from heavy AA towards rapid-firing light-medium AA has been a function of its apparent lack of utility. Ultimately, this will come back to bite, I'll have to develop a new heavy AA weapon or do a bunch of refits in the 1930s or so when aircraft get much more serious.

When I was running the Mayan war, I gave the Mayans a pass on QF vs. AA mountings
since they were a quickly built and reviewed navy.

For players, if it is in a QF mounting, do not expect it to function adequately against aircraft.
To me, that indicates a low angle mounting, not necessarily meant for fast traverse and elevation.
Certainly no fuse setters, so all HE.
Buried under Snip's Research, Gun Research, there's a bit on updating mountings.
To me that means mountings type listed in the SS matters.
You can update that to a different type/year via that section.

I realize other folks running battles may look at that differently, but felt I should be clear.

For my part, I developed my 57mm AA as my 90mm AA really didn't fit on destroyers.
I'm placing it my ships, but I recognize it's too big to be fast, and too small to have a good lethal radius.
So it will get replaced with the next generation of weapons.

As I have specified since the beginning of the game, I use the naval artillery of the United Kingdom, source Naval Weapons.
The 47/50 cal Vickers gun.

http://www.navweaps.com/Weapons/WNBR_3pounder_V_mk1.php

This one has an elevation angle of 80° and was also used during WW I as an AA gun.

I declared it in my SS as QF because aviation is currently very underdeveloped. I therefore consider it ,first, as an anti MTB gun.

In a few years, it will be replaced by the 40/39 cal.
