There was very little difference between the Bibb/Treasury (327') class USCG cutters and the US Navy Erie class sloops, mianly because the Bibb/Treasury class was based on the Erie's design). They where huge (well for cutters) with a standard displacement of 2,216 t and a full displacement of 2,660 t 3 × 127mm, 3 × 76.2mm, 2 × 40mm, and 4 × 20mm. In game terms if they where to be destroyers they would be large destroyers or 2500 t destroyers which isn't an accurate representation of the ship's ability or an accurate comparison to other ships of that type as they often mounted heavier guns then 5'. In fact I've been talking to MateDow if we should bumb them up to treaty sloop and made the Haida class USCG the basic sloop. I'm not saying all USCG cutters where that capable, or even that displacement is the one defining factor, the Chelan, Northland, Active, and Argo class cutters are going to be put in the next patch as several flotillas of escort sloops along with the USCG patrol boats. As the war continued even larger USCG cutters where designed and built, the Northwind (270') class cutters exceeded 3,500 t and three where loaned to the Soviet Union. The Owasco (255') class, although smaller then the Bibb/Treasury class was equally as capable. We can't make every single type of ship that ever escorted a convoy to be able to put them in the game in such an abstract way, in that case the entire Regia Marina would be in the escort pool. In terms of the ship class herself in comparison and date of construction to other ships, they easily fits the role as a sloop.
