Just like Danes configure Iver more as AAW Frigate, seems this is also what TNI-AL plan to do with FMP. Question will be if the SAM missile that going to be equiped will be more for Short to Medium or long range. From what I gather potentially more to Short-Medium range first.
Just like TNI-AU that has NASAMS with AIM 120, TNI-AD Trisula system in begining will also equiped more with Hisar O/RF that has similar range between 25-40 Km. TNI-AL FMP Midlas also reported potentially will be equiped with similar HisarO/RF. While their PPA potentialy also will be equiped with similar range Aster 15. All three then operating 25-40 km range SAM.
There're talk for Hisar U/Siper and Aster 30, but seems it will be for next round budget allocation. Roketsan already shown their Midlas can accomodate both Hisar O and Siper, just like Sylver for Aster 15 and 30. Will see what type of Midlas and Sylver that being procure, as rumours say the Light + PPA equiped with Sylver 43 and not 50. Means only can be equiped by Aster 15.
Video on KRI Brawijaya trial in Italy with TNI-AL crew. Just got a feeling if TNI-AL PPA equiped with Aster 15, then potentialy FMP will also be equiped with similar class Hisar O/RF. Still it is already improvement then VL Mica and Mistral.
From what I heard TNI still want to evaluate Siper as it is relatively new, while Hisar O/RF already operational for some time
TCG Istanbul (F 515) Fires HİSAR-D RF Missile from MİDLAS | TURDEF. Personally I see it more to budget issue. Having 25-40 km SAM is in the end more economics then 80-100+km SAM. Also more importantly TNI can done gradual learning from Shorad to Short Range then Medium Range before operating long range theater defence SAM.
