The Cypher System core rules has four stats for Star Ships: Level, Weapon Systems, Health, and Damage.

I like how Ryan Chaddok converted the common Star Trek ships (using the most excellent Last Unicorn Games book as a source).

There’s a starship vehicles table on page 255 of the CSR.  Importantly, it has Levels and a column called Weapon Systems, indicating the number of different target the ship can attack at once. Looking at the starships in the Star Trek game by Last Unicorn ships happen to be on a size scale from 1 to 10, ranging from shuttlepod at 1 to Romulan Warbirds at 10.  This would seem to be a perfect way to convert:  Size = Level.  Rather than going all the way up to 36 Weapon Systems as the CSR does, let’s just go with Level +1 for ships above Level 3.
