Fleet Action, strategic-subs no, but as raiders, ambushers, Oh yeah…
On the other hand, I have been caught with my pants down, so to speak,
by having a CV and 2 FTR, being caught by two subs- it was not pretty- good bye IPC’s. Keep several DD handy at all times-LOL.
I see no reason why Japan’s fleet action can’t consist entirely of raiding subs. Scatter 6-12 Subs, with no more than 1 Sub per sea zone within range of a Destroyer, and America will be forced to invest in a fleet of Destroyers, which even if it is successful, has no actual ability to attack Japan proper, who probably has 50-70 Income.
A minor US fleet, with two or three BB, one or two destroyers and a transport would be a pain to take out. Besides: I believe the Japanese aim is not to defend Japan, but to dominate the entire Pacific (with Japan herself not even threatened).
The subs would allow Japan to dominate the Pacific. Japan should build 7 or so Subs J2, 6 Subs J3, and 5 Subs a turn thereafter as needed. So long as Japan spreads them out to a density of 1 sub per sea zone, the US will probably have to spend 40 IPCs a turn on Destroyers in order to a punch a decent hole in the Subs, and even that will be slow and take time. If they don’t mass Destroyers, the Subs simply obliterate the American fleet on the counterattack. If they have Super Subs, it will be even worse.
The thing is that Japan doesn’t really need that many reinforcements to secure all the territories they wish, which means that they can afford to waste 30-50 IPCs a turn on Subs. America, in the mean time, needs to organize an invasion force with Transports and either Carrier Groups providing air support or Cruisers/Battleships supplying bombardment, all of which must be purchased on 40-50 IPCs.
