Most probably won't see fifteen years. Their export potential is nil. They cost to much to run for the Coast Guard to even consider them. Even for free.
A disastrous program. Vague purpose from day one. Mission creep. Equipment promises never fulfilled. What was intended as a fast, relatively inexpensive, coastal corvette with modularity turned into technological and programmatic cesspool. We could have bought small MEKOs but noooooo. Not invented here.
