The eleventh Sōryū-class submarine (Ōryū) is the first Japanese submarine in the fleet to mount lithium-ion batteries. The JS Ōryū was given a budget of ¥ 64.3 billion (equivalent to ¥ 65.55 billion or US$601.3 million in 2019) [8] under the 2015 Japanese Defense Budget. [9]
However, the Taigei-class submarines will be more advanced as they are equipped with newer equipment such as sonar systems, snorkel power generation system. The Taigei class will use lithium-ion batteries much like the JS Ōryū and JS Tōryū submarines. [25] The submarines use the Type 18 torpedo , a successor to the Type 89 torpedo. [2] [26 ...
Attack submarine (AIP lithium-ion batteries) JS Ōryū: SS-511 2020 The JS Ōryū is the world's first submarine powered by lithium-ion batteries. [7] JS Tōryū: SS-512 2021 Taigei-class: 3 (+2 ordered, +2 planned) Attack submarine (AIP lithium ion) JS Taigei: SS-513 2022 3,000 tonnes (surfaced) Total planned of 7 [8] JS Hakugei: SS-514 2023 ...
A fuel-cell powered air independent propulsion (AIP) module for charging lithium-ion batteries (LiB) which allows it to remain submerged for about 50% longer than the Archer-class submarines; several estimates put the Type 218SG's underwater endurance at about 28–42 days (4–6 weeks), without snorkelling.
The first lithium-ion batteries for the DCS were delivered to the Navy by General Atomics in February 2018. [9] The Dry Combat Submersible reached initial operational capability with the US Navy in May 2023. [10] As of July 2023, two submersibles have been delivered to the US Navy, with work being finished on a third. [10]
Lithium-ion battery power stacks are being developed to increase the underwater endurance of Jang Bogo-class submarines by two to three times, offering four to five times the power density of Type 209's current lead-acid batteries and as much as twice the power density of Type 214's BZM 120 fuel cells. [24] [25]
The submarine's design also features a flexible weapon launching system - which can be tailored according to the customer's requirements. [16] Similar to the KSS-III, the DSME-2000 will also be equipped with an AIP module and lithium-ion batteries. [16] The design also includes an assortment of equipment, including -
The first submarine in the class, Sōryū, was launched on 5 December 2007 and delivered to the navy in March 2009. The eleventh of the class is the first one that is equipped with lithium-ion batteries without a Stirling engine. [16] This submarine may have a range from AIP of 6500 nautical miles and can remain submerged for 40 days. [6]
