I am here not to be praised...... I am here to share my knowledge & experience being as a submariner.... as I know, just less hundreds of us only in Malaysia. U can ask me...And I could answer as long as u are serious

Ppl mistaken military sub has windows or camera to see outside..... which is not. Window does not give u range advantage at all.... how far can u see under the sea?? We dont speak in meters for detection range, we talk about kilometers, which only soundwave can provide.

Using passive sonar,we could detect the present of biologics around us. Yes, we could collect the data if we are required to do so

Not required... but to enter port of calls we need to submit the requirement thru agents. When transitting thru international waters & territorial waters no need

Yes...always. we could differentiate the sound from which biologics

Yup....it happened. One of it between french & UK subs

For navigation light at surface

go to 2.30  they also senget when diving

Navigation light on surface navigation.

Yup...when ascending or decending, we stand like that.... if not secure properly other things will start to slide.

Mesti bai..... nk tunjuk tp x de dlm rekod plak video or pic dia

We cant simply post any sub interior scene for public....especially in ops room

1. Officers share also....only captain has his own little room.

2. Yup... hot bunk. We do this... 3 person share 2 bunks

3. Every person is assigned with own bunks. Some needs to sleep beside, on top or below torpedo

Confirm same. I am not navy submariner but I had been there wt them.
