Well, we have a truck, and we will possibly have an AA truck next turn or the turn after. This would increase our mobile anti-air power - in the island defense role, however, the AA gun alone should have the desired effect. Maybe use it with a to-design armoured transport vehicle?
On the mines, I have a different, more critical view. We already have basic naval mines (the cruiser from the beginning has mine laying equipment which I assume to be contact detonated ones). More advanced ones, operating for example with a magnetic proximity sensor, would need new technology and therefore be new projects, while contact mines will be - for island defense - very useful.
There are two usages I can see for mines: Mining sea ways and mining island coasts. The former will mostly impose strategic disadvantages to our enemy - the need to clear those mines. Useful, but commerce raiders and submarines should be more efficient. The second will mean to mine the approaches they have to take to the shore, so they have to clear the mines under fire from coastal guns. That's more useful, but our current ones should suffice.
Additionally, they shouldn't be that similar to anti-infantry and anti-tank mines. Basically, naval mines are heavier and use different detonation mechanisms - and don't need hollow charges or shrapnel. It's probably like developing a motorcycle or a tank - different parts, but some small are the same.
Oh and for strategy I wanna add look out posts on the mountain, well supplied infantry can get across it on foot so we need a warning system. Plus we can map it incase we ever invade our neighbour to allow us to cross it.
Do you mean lookout posts to look for invaders, or to map the land they can see from there? The former is useful, and will probably be done along with scout flights to see them before they're only an hour away, the second one will probably not work for any meaningful distance between the island and mainland.
and are going to have a rocket testing range that we can make SAMs from in a decade or so.
We'd need guidance modules, among other things, before that. That might take a while, more like two decades. They will be needed, but I myself prefer better aircraft...
What I'd like for next turn are four things:
- A better torpedo
- A better torpedo boat - using the newly developed engine (2301) and torpedo (see 1) we can probably see pretty good commercial raiders from a forward base - like crow island.
- A fighter plane - we need some air cover, and it's either that or a heavier naval patrol and torpedo aircraft, which should probably come next year.
- A tank. Honestly, last time we developed one in 1920 ;-) It should provide us with anti-tank and anti-infantry firepower that we can use to either squash pretty much a sea invasion without enough artillery and air cover (a.k.a. what probably awaits us) and use them on a land-based war. We sadly lack a highly armour piercing design, and would need to use the 40mm cannon for now, but we could also develop a high-speed variant of that.
Oh, and a question to AseaHeru: What exactly should the planned combat role for the APC? I principally like such a role, but I can't get me an opinion without things like armour strength and armament. Plus, I believe that for the next turn, a real tank is more important.
