This is article from Jane's that talk the length of upgrade being done for
Bung Tomorrow class. Those three Light Frigates ex Brunai Nahkoda Ragam, basically being procured never been use by Brunai. However the systems already now two decade old and is already in time for MLU.
This close the speculation whether Turkish Havelsan or Danish Hensoldt will steal the MLU deal from Thales. Personally I do see those three will share the cake on TNI-AL Mordernisation projects, even on new builds. Still Thales seems going to get bigger share with the rest divided between Havelsan and Hensoldt. Leonardo can potentially get some, if Fincantieri manage to bag some deals (as now there's discussion being rumours to change FREMM deal to PPA).
Is still three electronic and sensors systems OEM, but for TNI standard, narrowing the suppliers from Euro Zone (well Havelsan still can be considered that), is already standardize move.

Information from Dutch Navesbu which being choose by PAL as their "consultant":
Naval architects since 1935

From Navesbu 3D design, it is seems comfirm that Bung Tomo class VLS being change to VL MICA. This is good as this means the Short-Medium Range anti air VL, will be standardized with MICA. This is also good for TNI logistic foot print as TNI-AU with gaining Rafale and Mirage 2K more likely going to be MICA users.
It is going to be 12 VL cell for MICA. Similar load as what being put in Sigma 10514 Light Frigate. Potentially rumours also going to be similar with Sigma 9113 MLU later on.
