Hi,
Don't forget the little deckhouse forward - it's part of the DG complex and has the exhaust on top. I'd also note that the older ships have a grey RiB for use by Large Blokes With Guns, and also IIRC 30mm guns on the superstructure. The latter would limit their ability to enter some ports, however.
RP1
Thought about arming her but also thought about that, would the same apply if she just carried armed security? And RiB?
I have a newer drawing with a forward deck house and washing down equipment but still working on her at up the moment.
