Till now, the Soryu submarine and its distinctive technologies have been a closely guarded state secret.
But the Japanese navy, or the Maritime Self Defence Forces as they are identified, gave North Asia correspondent Matthew Carney an exclusive look at the Soryu at the Yokosuka Naval base on the outskirts of Tokyo.
Numerous believe the Soryu is very best traditional submarine in the globe and ought to be the leading contender to replace the Collins class submarines.
The Japanese are now in a race with the Germans and the French to win Australia’s most significant ever defence contract worth almost $ 50 billion.
The characteristic is secrecy. We can go into enemy territory with no getting found out since we emit quite small sound.
Commanding officer of the SS Kokuryu, Takehiko Hirama
I was taken to see the SS Korkuryu (black dragon), which was completed in March 2015 and is the really newest from the Soryu class.
The Japanese are hoping that the 12 submarines will be patrolling Australian waters by the middle of subsequent decade.
Submarine warfare is determined by how quiet and deep a sub can go.
The commanding officer of the SS Kokuryu, Takehiko Hirama, stated the Soryu had the edge more than all other standard submarines.
“The characteristic is secrecy,” Commander Hirama mentioned.
“We can go into enemy territory with out getting found out simply because we emit extremely little sound.”
Each piece of the submarine is developed to minimise sound signatures or vibrations. Rubber tiles surround the sub as they deflect sound and sonar.
All the electronics are also covered in rubber to mute any noise, and even the light bulbs have had their sound signatures extracted.
The Soryu can also keep submerged for longer as a special Air Propulsion program keeps it down for two weeks.
Commander Hirama stated his submarine did not have to come up for air as much.
“We utilised diesel engines, but sterling engines and the AIP method means we do not require a lot air from outdoors to move the engines to generate electricity,” he stated.
The Hull is the important to the Soryu’s strength and its capacity to drive deep. It is produced with unique steel and the Japanese say that through precision engineering they have come as close as achievable to what submariners call the perfect circle.
The sub also has a secret X configuration rudder style that offers it additional stability
Master chief petty officer Katsuyuki Matsui from SS Kokuryu said he was proud to be a part of it because “its complete of world-class technology and it really is important to Japan’s national defence”.
Australia have to invest in education workers, former commander says
It has taken the Japanese 60 years of study and improvement to make the Soryu.
They are ready to hand over significantly of it but the big question remains: can these special characteristics be replicated in Australian shipyards?
Former Soryu submarine commander Toshihide Yamauchi said Australian investment would be pivotal.
“Investment is required on the Australian side and workers have to be created who have the expertise,” Mr Yamauchi said.
“If not, then it’s going to be tough to create.”
Mr Yamauchi warned unless capacity is built up, price range blow-outs and maintenance issues could plague Australia’s subsequent generation of submarines.
“Japan can provide the technical cooperation, [but] I would like the Australians to find out as several techniques as attainable,” he said.
“A culture of excellence has to be created.”
The Japanese stated they were prepared to train hundreds of Australian engineers.
The competitors for the submarine deal, the French and Germans, do have much more defence export expertise but they have yet to develop a conventional submarine like the Soryu that is large adequate to meet Australia’s strategic requirements.
