No I do not since they know what to do to maintain operations while problems in general are irregular in occurrence not knowing when it will happen next. If you can anticipate things it doesn't need to be a problem.

And I wonder where he got those figures?

The output of the Kawasaki 12Ｖ 25/25 SB-type diesel engines are not disclosed nor what type of generators they store.If you think all generators have similar energy output you are terribly mistaken.

now you are just playing with words.

besides the link Lethe provided, Soryu's diesels are widely cited with an output of 2900kw, since the generators can't provide more power than the diesel output, I'll accept the figure as correct.

Auhh again not paying attentions to details I see.
That's 2900 kW surfaced and 6,000 kW submerged, they limit the output when surfaced since the propeller screws are too near the surface creating violent cavitation that may damage the screw blades.
If you go by your own theory the Collins class only generates 5,400 kW making less efficient in generating electricity to charge the batteries compared to the Soryu class.

another fantasy from you. in diesel electric submarine, surface power refers to the power the electric motor can generator from electricity supplied by the diesel generator. that could be on surface or slightly below surface while snorkeling. underwater power refers to the power from motor when electricity is supplied by the batteries.

Sorry but wrong conclusion.

Diesel-electric boats don't work that way since the propulsion shaft is connected to the electric motor with no direct connection with the diesel engines. You can with clutches and a gearbox BUT even if you connect it directly the diesel engine at surface needs to maintain it's connection to the generators to provide electricity to the boat as well as replenishing power to the batteries, making an engine to propulsion shaft connection a meaningless feature with further mechanical energy loss through the clutch and gearbox.

The diesel when in operation always generates electricity to supply the whole boat as well as propulsion through the electric motor. On the surface as I said there is less need for propulsion and more need to provide energy to replenish the batteries.

Video Preview: DCNS SMX OCEAN heavy diesel electric submarine (SSK)

Xavier Mesnet, Marketing Director (Export of Submarines) at DCNS, gives Navy Recognition an exclusive preview of the SMX OCEAN that will be unveiled at Euronaval 2014. The interview was conducted at the confidential site of Bagneux where DCNS develops its combat management systems and conduct some research and development on future projects.

I just watched that video in full.

Very interesting.

It shows a UUV being deployed from a lengthwise hatch on the aft of the hull. A similar contraption supposedly exists for the PLAN's 032 test sub



Also interesting is the dedicated SOF hatch at the rear of the sail. You would think that may not be very good for noise reduction, but their willingness to stick that kind of add on aboard the sub suggests its contribution to noise is very minimal.
The new SSN supposedly launched by PLAN (093B or 095) apparently has a similar hump too.

France does huge naval business and exports by DCNS are outstanding, in comparison UK and BAE do nothing

Lol anyone else catch the badguy frigate as 054A?

I suppose the ship has really moved up in the world to be depicted as opfor
