A new generation of Japanese submarines will work on lithium-ion batteries

The Japanese Maritime Self-Defense Forces will abandon the use of an experimental air-independent engine in the construction of new Soryu-class diesel-electric submarines. Instead, the next four Soryu will be equipped with powerful lithium-ion storage batteries, Russkaya Planeta reports, citing the ministry's press service.

The changes will affect only the Soryu submarine, which will be laid down in April 2015 and three subsequent ones. Six previously built submarines will not be upgraded.

Submarines of the "Soryu" type were nicknamed "ninzdy submarines" in the press not only for their stealth, but also for their powerful weapons. Their 89 class torpedoes are capable of inflicting damage even on an aircraft carrier. They are capable of covering distances of up to 11 kilometers, rising to the surface much less often than other submarines of this class. Their displacement is 000 tons with a submersion depth of up to 4200 meters. "Litter" is one third more than Western submarines using air-independent technology.
