Future South Korean Nuclear Submarine Seen As Threat to Japan

On October 17, 2019 Anonymous provided the following useful and timely comment with links.

The South Korean (SK) Navy officially admitted it is making efforts to secure a nuclear submarine [1].

On October 10, 2019 the Chief of Staff of SK Navy officially announced that an SK nuclear propelled submarine is the most convenient way to follow and destroy North Korea (NK) submarines that are capable of firing nuclear tipped submarine launched ballistic missiles (SLBMs). 

The Chief of Staff of SK Navy also stated  that an SK nuclear propelled submarine could be a "useful deterrent" against neighbouring countries. [Pete Comment: By "deterrent" the Chief of Staff of SK Navy is presumably meaning SK missiles with nuclear warheads as a handful of missiles with  conventional warheads would be no deterrent (particularly to nuclear armed NK)]. 

The Chief of Staff of SK Navy explained that an SK nuclear propelled submarine is not restricted by the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) or Safeguards Agreements of the International Atomic Energy Agency (IAEA). 

The Japanese government will interpret “neighboring countries” to mean NK and Japan and that SK Navy considers Japan as a virtual enemy [2]. This is because the SK Navy would never attack heavily nuclear armed China and Russia.

Pete Comment - The South Korean SLBMs may become a longer range variant of the land based Hyunmoo-2B (range with 500kg warhead 800 km in 2012?) or of the future Hyanmoo-4 (likely to have a range, with 500kg warhead, well over 1,000km).

Japan has already noticed South Korea (SK)’ s suspicious intention[1, 2]. According to representative SK paper, SK studied “the Stinger Strategy“ to hit Tokyo in 1990th [3].

[1] “Basic design of the next 3,000-ton class submarine has completed in South Korea. Scheduled to be built from the late 2019”, Masahisa Sato (Secretary General of Diet members caucus of Liberal Democratic Party, Vice Minister for Foreign Affairs)

“According to a Korean announcement, the submarine is built to respond to threats from all directions and can equip with six ballistic missiles with a range of 500km. Where is the main enemy of this submarine? What's SK intent?”

“South Korea's defense budget is expected to exceed 50 trillion won (424B USD, 621B AUD) for the first time. The government explained that it will increase defense spending to prepare for the conversion of wartime operational rights, but it was confirmed that there was also a name for the construction of military power to check neighboring countries such as Japan and China.”

Another concept of independent defense against neighboring countries is the Stinger Strategy. A government source asking for anonymity said, “At the National Research Institute of the 1990s, we studied how to fight in a dispute with neighboring countries under the name of Key Research. It's possible to hit the core of it. In other words, the strategy is to neutralize the command or major facilities in Beijing or Tokyo.” (Only SK version)
