Feanor..do you have info who's the six submarines will be for besides Vietnam..?? I don't think all 6 will be for Vietnam. From other forum Venezualla still mentioned, but the others is for Algier and Indonesia.
In here we also not really sure if we still go ahead with Kilo's..the signal still conflicting only say that the decisiion will be put in June. It could be Russian ones..but German 214 also mentioned..
Sources in here say we want Amur due it's newer design and can potentially matched 214. However other source still say 2 kilo's still included within USD 1 bio deal with russia. That sources say since we want 8 subs..than the deal will be 2 exsisting 209, 2 Kilo's..and 4 new build (still being decide wheather going to be Amur or 214)...but again the Kilo's still increasingly in dark
I'm not surprises Vietnam will buy submarines..and with their experience mostly with russian equipments..then russian subs is reasonable choices. Until the arrival of Singaporean subs..South East Asia for few dacades only known Indonesian subs (first the Whiskey and later 209)..offcourse the Thais used to have subs back in the 40's..
Thus with SIngaporean has them, Malaysian also, we set to increased our subs fleet, Thais probably will soon (after they can decide their political squable)..then it's reasonable Vietnam also want ones..
That's I believe that set Australian to have a dozen subs...increasing under water arsenal in SEA and off course increasing sophistications of Chinese and Indian subs..means the under water environment in Asia soon will become more interesting..
