What do you mean with "in one pass" ? In one pass of one of the planes, or the three?
Data: the MK3 + Statue is 182 damage, 3094 against defenders, HP is 2756
A tower level 9 is 2624 damage?
But as I don't know what you mean, I can't clarify, but if you mean the three planes against a tower, yes they do.
In fact I'm very happy with the Statue. I thought about the Kremlim, but I'm an offensive player, and the Triplanes with the Statue are super good. And my Zepelins has more damage than a maxed one without Statue I think... So even at level 1 I have it, it is an option too, although for getting the most of Statue I go with the 3 planes.
