A casual player like me with just one TankHatsu and one Ka-Mi could really need some more (even though I often send just two fleets to expedition). It depends on the other rewards of a quest, but rocket dev mats aren't that important (I got two from event) and T96 LB bombers are buildable. However, screws are always rare for me, so getting another anti-land-base boat will take some time. Not a problem!

Since you stated you already have 1 of each type, you will only need to build 1 more of each at the minimum. I say 'minimum' because every single tutorial, resource, veteran or other source of advice that I have seen since starting this game in May 2017 has indicated that to be 'event ready', one should have 2 KaMi tanks and 2 Daihatsu (the *HIGHLY* reccommend the T86, but a regular or Toku Daihatsu work well enough).

I'm not going to tell you that you need these things to get anywhere in the game, but I will tell you that they will make your life a LOT easier if you do.

This being said, the Screw costs to upgrade a Daihatsu to a T89 Tank & Landing force costs the following: - Daihatsu +1 -> +10: 14 Screws (minimum, assuming you don't do the 'auto-success') - Daihatsu +10 -> T89 Tank:7 Screws (you want to use the auto-success here, because if you fail, you lose that +10 Daihatsu) - T89 Tank +1 -> +10: 24 Screws (minimum, assuming you don't do the 'auto-success') - T89 Tank -> KaMi Tank: 9 Screws (you want to use the auto-success here, because if you fail, you lose that +10 T89 Tank and all that work up to this point!) Total: 21 Screws minimum to get a T89 Tank  from a Daihatsu and 54 Screws to get a KaMi Tank from a Daihatsu

Yes, that seems like a lot, but don't discount the benifit from the daily upgrade, which reduses the upgrade cost by 1 screw. Also, take into account that this is also a long-term investment as well.

Since screws are an issue for you, I would look at trying to complete as many Weekly & Monthly quests that provide screws as possible. If you are cautious and frugal, you should have no problems in having enough screws to do 1 upgrade per day that costs 2-3 screws and doing the auto-complete won't break your bank.
