Sensors are mainly Japanese,
Major US systems are CIWS (SeaRAM) and Mk41VLS, the prior is easy to replace with any kind of CIWS, the latter will definitely be leased for Indonesia, why not? Along With ESSM or SM-2.
SeaRAM (or RAM) is luxury for Indonesia, too expensive per-missile,per-system for the range it provides. It won't be a big deal to add Millennium gun there.
Even propulsion is British RR.
That guy (Alman) is so pro-European he is blinded by the facts.
FREMM has got US- GE LM2500 gas turbine.
