I’m sorry. Did you read the article?
The new OPV’s will (probably) replace the ships you see in the picture and are nothing to do with the T26. What we’ll get will be a derivative of the River’s probably something like the Krabi we sold to Thailand. Bigger, more capable, so actually an improvement.
The CGS’ are something entirely different, see below;

I did read the article, although not the wikipedia piece. Entirely different. LCS lite, revenue cutter plus. Not exactly a Ship of the Line, is she.
