Destroyers- Cost 7 and Attack is 1 and Defense is 2.
Submarines- Cost 5 and Attack is 2 and defense is 1 and aircraft may attack subs without a DD but the sub may choose to submerge and the aircraft gets one shot at killing it.
Any comments?
My thoughts:
DDs: Your stats would mean a pack of DDs attacking a pack of subs would be an even battle, with the subs defending at “1” - when clearly the DDs would have an advantage with their speed and depth charge ability.
Subs - pretty good except the price of “5” makes subs too cheap - especially if you combine them with a “navy production” tech, where they would then cost “4” - you could spam the oceans with them.
About A1 Destroyer, I could rationalize it that it is harder to search and destroy subs in open sea rather than waiting for a torpedo trail against an escorted vessel and react against the attacking Sub with hedgehogs and depth charges. A1 includes the search result. 50% to find and 2/6 to hit = 1/6 on attack.
In an old WWII The Expansion from Philip Schwartzer, DE Destroyer Escort got A1D2.
The search, named Anti-Sub patrol, was 2/6 and the attack roll 2/6 vs Sub only. Sum: 4/36 which is less than the A1 suggested.
Besides, if planes can shoot submerging Sub the issue would become that Sub are going to be sitting duck with no retaliate roll against planes only attack. DD won’t be as necessary as OOB.
My idea to simplify interactions between Subs, planes and DDs still requires that Subs keep their surprise or submerge phase when destroyer is not present. So, a planes only attack have no impact on enemy’s submerge Sub. This imply that at least 1DD must block Subs to let planes a chance to hit unsubmerged Subs.
Also, DD A1D2 increase the need to bring along planes to be more efficient while on offense searching and seeking to sink Subs. Something which is historically correct.
