Has Myanmar placed order for some submarines as yet?
I'm asking because usually Navies in the world place order for submarines first after evaluation and then train their crew so that they are ready to operate the sub as soon as it
arrives.
The same was done by Vietnam People's Navy, they placed order for 6 x Kilo-class SSKs and then began training in India to operate the Kilo subs when they arrive (which is very soon from now).
If you train your crew too early, they may even forget all the tactics learnt in the training programme by the time their sub finally arrives.
Since I haven't heard any news of a solid purchase agreement from Myanmar's side, I believe the crew are infact being trained in basic knowledge about submarines. How to evaluate them, gauge their individual capabilities, measure parameters and finally make a choice.
