There are multiple types of Auxiliary weapons that function differently from one another. There are those that deal huge AoE damage and some that apply DoT (Damage Over Time) to foes. Some serve as support weapons that heal Hull Health of allies, while others act as siege weapons that deal increased damage to structures.

What are Auxiliary Weapons?

Backup Weapons with Long Reload Time

These are special weapon types that are used as backup weapons and can only be placed on the Auxiliary slot of your ship, provided you have one.

The weapons under this type deal insane amounts of damage but have very long reload time, with some weapons used as support weapons for other ally ships to restore Hull Health.
