Unless Fairy Tail had the necessary money and resources to make their own larger and more powerful version of Jupiter Cannon, they just have only one howitzer-sized cannon for now. Ajeel just blocked it with just his hand because such weapon fired by Bisca wasn't much stronger than him but it was powerful enough to destroy several or more ships got caught in its scattering.

The Lockon from Gundam 00 shoutout was on Bisca! :D All Fairy Tail needs is a Fairy Tail Mage Mecha Guildhall like Phantoms lol.
