I could just be misinterpreting the rule, but i think that tyranid assault boats dont disappear after attacking a ship. In the main rules section it says that after attacking a ship the assault boats return to the mother ship to reload and refuel, causing them to be removed from play, but in the tyranid rules it says that their ordinances dont have to reload or refuel like other ordinances.

They are removed from play, but you do not have to use a "Reload" order to be able to fire them again from the launch ship.

Basically, you can shoot them every turn like a normal weapon.
