Look here for sub recipe (there's a chance, doesn't mean it'll show up): http://kancolle.wikia.com/wiki/Construction

Subs are good but not mandatory. 1 sub won't help you clear 2-4 but can help you do 2-4-A grinding.

I'll also reply to your previous post. 2-4 is a pain in the butt. Don't expect to clear it easily (and as anon said, don't proceed if your ship is in the red). I'm taking a guess that the aircraft carrier you lost was Akagi and believe me, she's a pain to get a new one for new players. You don't want to lose anymore ship!

For now, I suggest you to calm down and go slow and steady. Kongou won't be going anywhere and you'll get her eventually. This game does test player's patience.

You got 2-4 unlocked. If you have at least three carriers/light carriers (and possibly 1 BB) you can try doing 2-4-A grinding. Kongou does drop from 2-4-A so who knows...you might get her while lvling up your girls.
