This question is rather ambiguous. If you’re attacking with aircraft only (no land units), it’s not an amphibious assault. If you mean, “Can I conduct an amphibious assault without cruisers or battleships for shore bombardment?”, the answer is yes, you can.
When conducting an amphibious assault, you have to choose which aircraft will participate in any naval battle and which will participate in the land combat; they cannot do both. Any naval battle must be resolved before amphibious landings can take place.

Besides… it’s not about when you buy battleships as much as it is about how you use the ones you start with.
And yes, 2 or 3, with a carrier mix are great, I LOVE the Strafing Navy… Carriers can’t do that aswell, because the fighters can’t land on them after for the retreat! And you can only scramble up to 3! :S
