That's OPV, they are build more on patrol endurance. Those Bakamla OPV that I read on builder trials claim can get to 20+ knots, but I do agree with 18 knots probably the most they will be operating with.This "Bakamla 11015" design with 4600 nm range (but with just 18 kts way too slow), is actually a very nice design, inspired by the SIGMA 9113.
As for weapons, OPV will mostly have basic weapons, thus I'm not even surprise if some weapons from Parchim still can end up in those OPV's.
They will costs more than those Bakamla OPV's I believe, as they will build with more Naval standard. In my opinion it's better those OPV's got second hand armament from retired vessels, but have good solid sensors and electronics.
