From PAL FB, on what seems the latest iteration on KSOT.
There's hatch on top the sail. I don't know whether this is means it is have option to be manned and unmanned. Previously it is said the option is there, but it could also be the hatch for maintenances.
Thanks for sharing. I wonder how long KRI Cakra 401 stays in the fleet. The most logic step is to order one more Scorpène class boat, for a balanced 3-3 submarine
Cakra being said only maintained as training submarine. With the DRASS midget submarine and KSOT underwater drones, I suspect MinDef potentially looking on approach that can provide more quantity but in more affordable approach.
There're rumours that after all 3 209-1400 being satisfactory refurbished, potentially another 209-1400 will be supply by Hanwha Ocean as some materials for that submarine already being prepared by DSME. Personally I suspect some settlement on Batch 2 contract should be reach, or PAL and MinDef must paid some penalty to Hanwha. Something that not politically acceptable.
So in my opinion and considering fiscal pressure that Indonesia now facing, 4 209-1400 (with additional one as Cakra replacement and Batch 2 settlement), 4-6 DRASS (whether DG-550 or DG 900) and 2+2 option Scorpene can be the underwater defense approach that will be taken.
As the interim submarine, the option still there, but so far no Interim options whether for Submarine, Frigates and MRCA//Fighter being finalized, despite all the talk. Still knowing Indonesia, that lobby for Interim assets still there.
Add:
Seems most risk assesment to detour KRI Prabu Siliwangi 321 avoiding horn of Africa, and choose instead Cape/South Africa route paid off. Yemenis Houthi already stated they will again attack US and Israeli warships. With that situation, why bother to gamble on newly delivered warship where most of is arnaments still not activate.
