Well i hope DSME can solve the technical problems with the Nagapasa class, three new submarines with ToT and end assembly in Surabaya for $1,1-1,2 billion was a great deal. I also hope that KRI Cakra 401 is reliable and fully operationable after the modernization.Perhaps he's one of DSME sales agent that now vented his frustration. Who knows. However one thing so far that not really come to public knowledge the extent of the problem from those 3 DSME 1400. So far all the talk officially related to batery and recharging performance.
However I suspect more than that. This guy comparison on DSME Chang BoGo is also not entirely accurate, because DSME offer 'bit' bespoke system integration that's not follow their own Chag BoGo specs.
What create problem seems related to combination of Nanggala Incident (as that Submarine refurbished by DSME), cases in DSME 1400 being blown up by some defense "insiders" to media, plus DSME attitude that seems consider deffensive. Whether this related those agents and some in MinDef officials gank it up to uses it as giving excuse for Euro suppliers, is something I can not prove but highly suspect.
One thing for sure problem on new design (as DSME 1400 to Indonesia actually do have some "bespoke" design on system integration), happen all the time. Seems DSME still going to be ask to provide job with PAL to rectrovitted modifications work. However this's going to left some bitter after taste on Indonesia and ROK defense relationship. That kind of comment from that ex ROKN Capt seems part of that.
Surabaya (12/07) Manajemen PT PAL Indonesia menerima kunjungan Chief of Naval Policy, Republic of Korea (ROK) Navy Mr. RADM. Kang Chung-Ho beserta jajaran ROK Navy yang diterima langsung oleh Senior...www.facebook.com
I suspect this's part of Indonesian and ROK try to mend the fences.
But to spread the risks i believe it is also a good decision to order the Scorpènes.
