It would work pretty well until you run into an opponent with cruiser/frig or sub stacks, in which case you would need to beg for mercy.

I imagine OP was suggesting to start with this strategy, not stick with it by the time opponents could have Cruisers.

I've done similar things (once as Cuba) but I usually only build a few naval bases and pivot to Destroyers pretty quickly. By day 2 I'd probably only have 2 Corvettes, but by the end of Day 3 I'd probably have a Destroyer and 3 or 4 Corvettes. If you hit me on day 2 I'd probably lose, but if you're busy with other countries I'd have the advantage by day 4.

Your strategy is decent but IMO having any slightly decent Navy early means you can beat most players who often seem to forget to have any (at least in pub games). I imagine committing to all those Naval facilities drains more resources than necessary, I reckon 3 is enough usually.

What I will usually do around day 10-15 is let my older technologies (units that I'm not investing to upgrade anymore) "die off", meaning let an enemy destroy them. This is to stop them from taking upkeep resources that I could be using for production/research. So yeah, as long as you are upgrading your stuff, you should be good to go.

Corvettes use way too many supplies for me to ever spam or make them, frigates are a much better value unit than corvette. And I would rather have Cruisers and Frigs anyways.

I do this a little bit and may spin up 3 or 4 vettes till get frigs (only 1 day bhind vettes). Think in all 7 cities may be over kill but does work early on in game; but then virtually useless 10 days in.

They use alot of supplies which will hurt your Research. Played with australia and think had 2 supply cities so always had extra supplies so built way to many, late in game just sat in all choke points in pacific as "sonar buoys" for early warning. Was ok/expected them to get killed at night but to my surprise night 1 caught a 21 unit transport; next night a aircraft carrier.

TBH thats way too many corvettes for that early, like 2-3 are more than enough.

I tend to have excesses of supplies, how are you guys using them all in the early to mid game?

This obviously wouldn't be the case if you built 7 corvettes :p

FIXED

research...

A two stack of level one corvettes wiped out one of my frigates in a Rising Tides game. Pissed off, I was.

I usually just build a few for early game and use them as a supplement to my main naval units mid to late game.

However, I am curious as to experiment with a 5 stack of corvettes to tangle with a lone frigate or destroyer but the conditions would need to be right where:

I have more than one naval base and an abundance of supplies.

5 vettes in shallow water will destroy a single frig or dest for sure probably 2. just do the math.

lvl 1 vette:

20 HP x 5 = 100 HP

attack Damage: 5 HP x 5 = 25

lvl 1 frg

28 HP x 2 = 56 HP
attack: 6 HP x 2 = 12

after 1st attack (assuming no hit and run) - cor (5 ships @ 88 HP) frig (2 ships at 31 HP)
2nd hr vettes firing @ 90 pct (22 hp) vs frigs @ 55 pct ( 7 HP) after corvette ( 5 ships - 81 HP) and Frig ( 1 Ship - 8 HP left)
3rd hr would end up with 4 corv - 78 HP and sink final frig

So would lose 1 vette and sink 2 frigs

lvl 1 dest

40 HP x 2 = 80 HP
attack: 8 HP x 2 = 16

after 1st attack (assuming no hit and run) - cor (5 ships @ 84 HP) dest (2 ships at 55 HP)
2nd hr vettes firing @ 90 pct (22 hp) vs dest @ 70 pct ( 12 HP) after corvette ( 4 ships - 72 HP) and dest ( 1 Ship - 33 HP left)
3rd hr vettes firing @ approx 18 hp vs dest firing at approx 6 HP after corvette ( 4 ships - 66 HP) and Dest (1 Ship - 15 HP left)
4th hr vettes firing at approx 16 hp vs dest firing at 3 hp after covrvette ( 63 hp 4th almost sunk) and Dest sunk.

So basically lose 2 vettes and sink 2 dest; This would be a blood bath other way in Deep waters. But same principle would play out in Frig stacks versus destroyers or cruisers as can produce greater numbers (strength in #s).

I will make a few in the early game to protect my homeland from naval attacks (sinking transports), but after Day 10, I will focus on advanced naval units.

same.. best use late in game i had shitton of supplies so built like 10 vettes. day 30 was like, what am I going to with these as not letting people come at my port (dudes had subs and missiles ) . so just sprayed out in every choke point in middle of pacific as "sonar buoys" expecting to get sunk but early warning system. and actually caught a 21 unit transport (unescorted but dude thought could sneak by antartica in rising tides.) and another one caught a aircraft carrier; which obviously a 10 hp unit cant take down a 125 hp unit even with minimal attack HP. But held it in place for 10 hrs till could get naval patrol and real navy stacks to come to rescue.

So late game... sonar buoy is best alternative use of vettes. I like to think of creative ways to use idol units. Like another game had ton of naval patrol (which is a must in open pacific naval dominance) but then used a few as long range "bombers" well firing CMs but still had like 3000 mile range and fire on stray inf coming in areas that were way outside my 900 mile SF range.

I run out of Rare Materials waaaay before I can use all my supplies on ‍♂️

I use all my cash day 1 to buy the entire avail rare material.

Ahh fair enough. I usually only buy some rare materials, I don't find spending all my cash on just that as valuable as buying some other resources (depending on what I plan to build).
