New ship refits, decalmore mod recommended.
Secpod Refit

$102,050 credits
18 crew
An upgraded version of the Secpod. It is now a dedicated flanker, meant to set fires before running away using its rear-facing shields and point defense. Yes, part of its armor has been replaced with scaffolding, but NanoTrasen ensures its employees that this is solely to make the ship faster.
Budget-class Skirmisher Refit

$160,700 credits
36 crew
A version of the Budget-class Skirmisher that isn't quite total garbage. It was cheaper to fit them with new weapon systems than bog down the shipyards breaking them all down for scrap.
Pillar-class Frigate

$424,600 credits
90 crew
The Pillar-class has been in NanoTrasen's possession for a while, but has only just been considered for combat. Typically an armored cargo transport, much of its hull has been stripped away to make it more agile.
Impulse Corvette Refit

$466,600 credits
92 crew
A refit that adds a tad more shielding and a pair of heavy cannons, yet is inexplicably much more expensive.
Chapel-class Corvette Refit

$472,200 credits
104 crew
The Chapel-class frame gets the job done, but its previous loadout did not. The Chapel-class has been equipped with more frontal shielding, better-placed point defense, additional armor, increased thrust, and additional energy weaponry.
Neruda Refit

$502,400 credits
124 crew
The previous Neruda-class frame barely saw combat because of its over-exposed thruster wings. It has since been refitted with additional armor, and its array of standard cannons have been replaced with heavy guns.
Rockpuncher Refit

$586,700 credits
144 crew
It really did not make sense for a ship designed to get close and personal to be equipped primarily with laser weapons. They may be plentiful and simple to reload, but that hardly matters when the Rockpuncher is meant to get the fight over with quickly. It has since been given a new frontal shield and big cannons.
