Couple of questions: 1. Do you build submarines? 2. How do you use them? I always build too large a navy and throw some submarines in for variety, I guess. I sent six regular subs out in a wolfpack and sunk a carrier in exchange for one of the boats. I lost a sub trying to sink the carrier, so I had to use a second sub to finish it off. That sub was redlined, but killed the carrier. For some reason the destroyer escorts turned and ran instead of easily killing my redlined sub. The sub had to limp three turns back to port for repairs so really it was out of the fight either way. Later in the same game I sent three nuclear submarines out to intercept another 3-destroyer, 1-transport invasion group that was headed for the coast. The result: I sank the transport and lost all three subs to the escorts when I tried to finish them off. I decided I'm not going to build them anymore, other than for novelty. I should have lost more regular subs but the AI apparently felt merciful and didn't finish them off. They seem to have too many drawbacks: low movement speed, defensive bombardment always seems to knock 1/4 of their health off before they attack, and they can't reliably sink anything bigger than a transport. So, they're not very good attack submarines. They're not very good nuke-delivery platforms either, considering they only hold one. The sub from Civ2 ruled...the ability to carry 8 missiles of any kind made them deadly. In my current game I'm going to have the remaining subs sail with my carrier group and deliver the killing blow against enemy surface ships I redline with either planes or other destroyers. Like I mentioned, I've concluded they're a massive waste of time and shields so from now on I'm going to build destroyers instead. Destroyers can serve as pickets, as better wolfpacks, as bombardment units in a pinch, etc. Thoughts?
