There is a simple solution for what the USN is facing, if they are smart enough to take it :
Take the Perry, strip everything off it but the hull, stretch it by another 10-20 per cent, and rebuilt it using the tech from the Burke. Problem solved.
I'm not sure if it's that simple or efficient to update a 1970s hull design like the Perry.
The bungling of LCS has left USN with no time to seek a clean-sheet solution, or appetite for the risk involved in that path, yet the candidates currently on the western market are less than ideal. The French and Italians are now pursuing "intermediate frigate" designs to follow on from the larger FREMMs, and of course the British plan to get around to Type 31 eventually, but in 2018 the pickings are slim indeed...
Still, it is a mess of USN's own making. Project management!
