Red Star Lone Star - Ship Identification Question

[johnfrum]

I have a (hopefully) fairly easy question that someone on the forum might know the answer to: what is the patrol boat type on the cover of 'Red Star Lone Star'?

I believe it's also the one that they have illustrations of in some of the rulebooks. I had initially thought it was a PBR but it doesn't look quite right. If someone could help me out, I'd appreciate it as my Google skills have left me down. Deck plans and any game stats would be even better!

With the soon-to-be retirement of the 'Corpus Christi' in my campaign, I'm looking to keep the amphibious nature of my group going and I think that 'patrol boat' would be about right.
