How do I increase accuracy?
Four ways, and you're already using one of them.
ATG: you're already using this.
Speed: core factor, and your missile is a bit lacking there.
ECCM: helps a lot if the enemy has ECM. If you have ECCM? (If you don't you should consider it important research.)
Retargetting: means your missile can keep attacking until it hits - but since that means running through point each time it's not so great for anti-ship missiles.
