The only remaining operational combat ship in the Aritan fleet is a Pentekonter-E (and even that needs repair) but there is one problem : its not wholly owned by the Aritans. The ship was jointly bought with Artic and is "time shared" between patrol duties for both nations. Artic allowed the ship to take part in the battle for New Arit against the ABBOs but now want it to perform some duties for themselves.
Arit need the ship for local defence though Artic also urgently need the ship to perform some duties for themselves. It is the only ship the Artic government operate and so is used for communications and transport roles to a number of small colonies too. The Aritans have offered the Articans two of their Coril shuttles to perform the duties instead. Artic is reported to be considering buying out the Aritans' share of the ship.
