According to reports, South Korea tested itsindigenoussubmarine-launched ballistic missile on Tuesday in an effort to strengthen its defences against a nuclear-armed North.
Last week, the Agency for Defense Development of South Korea conducted underwater ejection tests of the SLBM from a new, locally-developed submarine equipped with six vertical launching tubes, Yonhap reported, citing unnamed military sources.
According to reports, the missile is an upgraded version of the country's Hyunmoo-2B ballistic missile, with a range of 500 kilometres (310 miles). It is expected to be mass-produced after another round of testing.
With this SouthKoreajoins a very select group of countries to have successfully developed an SLBM.
As part of its budget request to parliament on Monday, Seoul allocated almost 1.5 trillion won ($1.3 billion) for defence technology research and development in the coming year.
According to a press release, this would result in a 76 per cent increase in the Defense Acquisition Program Administration's research budget, which would be used to "develop cutting-edge, future technologies".
North Koreahas long sought to develop submarine-launched ballistic missile (SLBM) technology.At the start of this year, Pyongyang demonstrated four SLBMs at a military parade headed by Kim Jong Un, with state media KCNA calling them "the world's most powerful weapon".

Even though North Korea has released pictures of underwater launches, most recently in 2019, analysts believe that those were launched from a barge or a fixed platform, instead of a submarine.
In addition, Pyongyang is seeking to further enhance its submarine forces.
Kim told a congress of his ruling Workers' Party in January that the North had completed plans for a nuclear-powered submarine.
Analysts say a vessel of this type is likely to be years from entering service, but that it could serve as a strategic game-changer, enabling Pyongyang to launch a surprise attack underwater even if all land-based forces are destroyed.
