Agree. That submarine would be noisier to a passive sonar. An active sonar would find it difficult to differentiate between the pier and the submarine itself, but it's still noisier. If the reactor is off, what would be the source of noise then?

Maybe the reporter got confused with 'launched' and being in 'sea-trial' ?

Ok, an LA class boat at a dead stop in the water with it's reactor plant on line still makes more noise than a Virginia class makes at 20kts. Put another way, a Virginia has to make at least 20 kts to match the radiated noise of an LA class boat that is stopped in the water with it's reactor plant on line. The difference in radiated noise between the two boats is that great.

India operates Kilos, a few German Type-209's and a pair of old Foxtrots. Six Scorpenes are on order from France. Pakistan operates 3 Agosta 90B's and two Agosta 70's, the four old Daphne's having been retired. Neither Bangladesh nor Thailand operate subs, but I had to smile when I tried to open the official Bangladesh Navy web page and my computer gave me a big lurid red lettered warning that opening that site might damage my computer, LOL!
Of course Iran has it's three Kilo's and is reportedly building the Qaaem "semi-heavy submarine", meaning apparently a sub over 1000 tons displacement. The Iranians have a number of mini-subs ranging from 25 to 150 tons.
Regarding the Indian Ocean, one must not ignore Australia's six outstanding Collins class boats, among the two or three best diesel electric classes extant. Most of these are based at Garden Island. Then there are the three Type 1400MOD's of the South African Navy. One must also consider that one or two Israeli Dolphins are out there in the Indian Ocean at all times.

Re: PLAN submarines Thread II
Don't to forget Malaysia, Singapore and Indonesia;
Malaysia used the french sub "Quessant" (Agosta-70-class) for training (was returned to europa) and now operate 2 french "Scorpene" subs.
Singapore as I know operate 4 swedish A12 class subs, additional in the future they will have two swedsh Vastergotland-class boats.
Indonesia at least have two german 209/1300 class subs. They are in negotiatons for russian (Kilo) or south-korean (CHANG BOGO) subs.
as I know these subs normaly don't operate in the Indian Ocean.

Advanced they maybe, the Collins class offer no real capability right now, as only one of them is operational at the moment due to all the teething technical problems, and Australia only has enough submariners to man three of them.
