Canadian Navy: Next-generation submarine introduction plan
・Focus on Japan’s most advanced warships, the Taigei class
・Four Victoria class submarines replaced
We will deliver a summary of articles published in vehicle news.
Submarines from countries surrounding the Far East:
New submarines are being commissioned across the board.
A new submarine is a weapon closely related to national strategy.
Canadian submarine:
In such a situation, Canada is located to the north across the Pacific Ocean from Japan.
Victoria class submarine:
As of December 2023, it operates four Victoria-class conventionally powered submarines.
Built in England in the 1980s.
Upholder class submarine commissioned by the Royal Navy in the 1990s.
Canada purchased it as a used ship and then recommissioned it.
Canadian used submarines:
The submarine is already nearly 40 years old.
The Victoria class suffers from frequent accidents and serious crew shortages.
Canada’s submarine operations system faces major problems.
Failure accidents in 2019 and 2020:
All four Victoria-class submarines are malfunctioning and are unable to operate.
Considering introduction of successor ship:
The military wants to update the Victoria class.
Canadian Forces CSRP:
The Canadian Patrol Submarine Project (CSRP) began in 2021.
We will collect and consider submarine information regarding the performance of future submarines.
Canadian Navy submarine introduction:
The Canadian Navy would like to have at least eight submarines, and ideally 12 submarines.
The number of submarines that can be operated at any given time:
If you want to keep one submarine operational at all times, you need at least four submarines.
Ships docked for maintenance and crew training ships will also be taken into consideration.
Canada and the Pacific and Atlantic Oceans:
Canada borders two oceans: the Pacific Ocean and the Atlantic Ocean.
It is necessary to have two ships deployed at all times for each defense.
Canadian Navy submarine renewal plan:
At the very least, a submarine force twice the current size is essential.
The problem is whether they can secure these personnel.
Japanese submarines are attracting attention.
Canadian Navy’s next submarine capabilities:
The following four points are emphasized.
1. Normal power type (non-nuclear) with diesel engine, generator, and battery
2. Excellent long-distance navigation performance
3. Operational capability in the Arctic Ocean
4. Can be equipped with US weapons and combat systems
Submarines that meet these requirements:
One of the names that came up was Japan’s most advanced submarine, the Taigei class.
Taigei-type navigation performance:
Equipped with a lithium-ion battery that enables long-term diving.
The navigation performance of the Taigei-class has been greatly improved compared to conventionally powered submarines.
Various American-made systems:
Due to the close cooperative relationship between Japan and the United States, it can be installed without any problems.
Naval magazine/STARSHELL:
STARSHELL, a naval magazine published by the Naval Association of Canada (NAC) (Winter 2023 issue)
The Taigei-class has been mentioned as one of the candidates for the next submarine.
nformation protection agreement between Japan and Canada:
Currently, in order to prevent military-related information leaks between Japan and Canada,
Discussions regarding the conclusion of an “Information Protection Agreement” are underway.
This information protection agreement:
It covers not only information between defense authorities, but also military-related industry and technology-related information.
A secret submarine:
It is no exaggeration to say that the existence of this agreement holds the key.
