From Keris FB, seems PAL on the process to install Aselsan CENK 350/Matehan Fixed Array AESA radar panels. This confirm so far that the installation will begin with Assets that part of Initial-Main contract. FFBNW assets, eventough the contract already execute, will be part on next instalation cycle.
From Indonesia Forum FB with id Markicap. Shown the 76mm main gun of OPV-98 is being tested.
The main force of TNI-AL is not the Frigates, but more on the Corvettes and Missile Boats. Presently it is the Parchim Corvettes and Luersen design FPB-57 FMB/FPB. Those FPB-57 being replace by indigenous designs KCR/KCP-60. More and more signs also shown Parchim corvettes replacement will be OPV-98 and Bung Hatta Light Corvette.
Three OPV-98 already contracted, 2 in the process of final installation, while the third still in building process in Batam. Batam made Bung Hatta class is not popular among many local enthusiats, however it is I believe more economical to build. In the end I don't think only one type will be choose to replace all 16 Parchim and also increase the number of Corvettes.
