RN frigates might prove too expensive for us. Anyway, we have some nice new South Korean frigates to look at, seeing were already locked into our Navy tanker build with Hyundai,and with thier reputation, thats where i think we should go next.
The South Koreans nomenclature / classification of their warships is different to how we would classify our warships. Their
frigate displacement relative to European frigates or even the ANZAC class is somewhat smaller at around 3,250 tonnes full load (2,300 tonnes empty displacement) for Batch I and around 3,550 tonnes full load displacement (2,800 tonnes empty displacement) for the Batch II ships. Having said that they are heavily armed with a 5" gun, 16 K-VLS, 8 SSM, 2 x triple ASW torpedo launchers etc. The Republic of Korean Navy (ROKN) use them for coastal defence. Their current
destroyers have a fully loaded displacement of 5,500 tonnes (4,200 tonnes standard displacement) with a 5" gun, 64 VLS (32 Mk 41 + 32 K-VLS), 8 SSM, 2 x triple ASW torpedo launchers etc. This would be the load out of a new European frigate such as the
German F125 for example. The ROKN have another destroyer class, the
Sejong the Great-class destroyers that are 11,000 tonne full load displacement (8,500 tonnes standard displacement) with 80 Mk41 VLS and 48 K-VLS cells That is a true destroyer in anyone's language. Yes I know I've used wiki, but this is for illustrative purposes only.
I agree with you that we should look to Korea for our next lot of combat vessels. 3 frigates based on the KDXIIA with the only changes being hotel with ships being fitted out for Kiwis, replace the K-VLS with Mk41 VLS, use the Sea Ceptors with LRASM for the SSM and increase the range to around 6 - 7,000nm. Keep the rest including AEGIS and the SPY-1D. 4 - 6 Offshore Patrol Corvettes based on the Daegu class FXII which is an upgraded Incheon class. Again the only changes being hotel with ships being fitted out for Kiwis, replace the 127mm gun with a 76mm gun, replace the K-VLS with Mk41 VLS, use the Sea Ceptors and LRASM for the SSM and increase the range to around 6 - 7,000nm.
