It seems the ship has defensive/offensive beam weapons only:
2 X Ph2 FA
2 X Ph2 SFBL
2 X Ph2 SFBR
2 X Ph2 RA
(and perhaps 1 X ADD 12 on later variants in the 2270's)
**END OF DATA***
The crew that it has is surprisingly low, which means that once it starts to take damage it will not be able to fight back very well. But at least it has a whole lot of marines so that taking it over is difficult.
It's basically a Coronado with way less wepaons but more transporters and marines. Btw I still haven't gotten it in my mail, but I'll be glad to adjust it for you. "
