Mr.Sandstorm
Casualy coming your way, stand by.
Addendum:
The top of the Propulsion Cap can be equiped to multiple purposes during interstellar cruising:
It has multiple ports that can mount high-power laser cannons, feeding directly from the powerplant to fire a battery of debree-melting and dust-ionizing energy.
It's surface can coat itself in thick water ice modified to absorve as much radiation as possible, and also aid in absorving impacts and deteoration
Lastly, the Mothership's Powerplant can generate powerfull magnetic fields to deflect radiation and ionized debree fields.
