The cruiser looks handy. Reminds me broadly of my Agra type.

CS hull strength is low on the last unit, though...

Ah. The dangers of reconstruction. Thank you.

As Rocky was kind enough to point out an oversight on my part, I took advantage of the necessary changes to envision a slightly more combatant Patrol Combatant.
