@Colombamike: it's not at all inconceivable that this frigate will end up with "hand-me-down" guns. Considering the steeply escalating cost to, not only design, but procure and build a ship of this size, any sensible government, be it Socialist, Liberal, or Conservative, would, in all likelyhood, attempt to shave costs whereever they can. So, if you already have ready-to-use guns in storage, then a wise measure would be to bring them up to snuff and fit them (Now, having said that, I confess not knowing much about the policies, either fiscal or else of the Dutch Government!)
I am FULL aware of this, I know all ,
:
Few examples :
- Japanese "Murasame/Akisuki" postwar
(late 1950's built) class destroyers => They used the second-hands 5"/54 Mk 16 guns
(1944/1948's era built, onboard the US Midway fleet carrier's during late 1940's/mid 1950's)...
- Danish "Peder-Skram" postwar
(mid 1960's built) class frigate => They used the second-hands
(even third-hands ?) 5"/38 guns
(WW2 era built).
- Italian "Impavido" 1st generation missiles lass destroyer
(early 1960's built) => They used the second-hands
(even third-hands ?) 5"/38 guns
(WW2 era built).
- Spanish "Roger De Lauria" postwar destroyer class
(commissioned by late 1960's) => They used the second-hands
(even third-hands ?) 5"/38 guns
(WW2 era built).
- Dutch "Tromp" AAW destroyer class
(early 1970's built) => They used the second-hands
(Bofor 120mm/50 model 1950, early 1950's built for the Dutch postwar destroyer "Gelderland") guns.
...Even I suspect few US 5"/54 Mk 45 mod 0/1
(1970's built) mounts to end-up onboard some Danish (Absalon class) or South-Korean (FFX/Ulsan FFG's class) or Spanish (F100/Alvaro de Bazan class) ships.
I have
Very
Extremely
Heavily
Doubts
that a 1980's built
(onboard the Karel-Doorman FFG class) 76mm Oto-Melara gun remain effective during 2020's/2030's against hyper-hypersonic
(mach 3+...) higly-manoeuvrable anti-ship missile...
At the same time
Useless
(around 2018/2024) to build a stealh-warship (with stealth-hull), if this ship carry a 1970's designed gun-mount...
