South Korea will be equipped with new weapons to counter North Korea nuclear and missile threats 10104161.

The armed force of South Korea will spend a total of 226.5 trillion won ($196.7 billion) from 2017 to 2021, the primary focus of which will be spending 7.9 trillion won in preparing against potential attacks from Pyongyang, said the Ministry of National Defense.

The annually announced five-year plan was scaled down by 6 trillion won from the 2016-20 version revealed last year, which the officials said was a result of adjusting 83 minor details.

The ground-to-ground munitions are directed to strike the North’s recently revealed 300-millimeter caliber multiple rocket launcher. The weapon is presumed to have a maximum range of 200 kilometers, which puts nearly half of South Korea within its range if fired along the inter-Korea border.

The guided weapons have a range of 120 kilometers and are expected to be put to use by 2019. South Korea is currently negotiating with the U.S. for equipping the weapons with U.S. military GPS.

Seoul’s 18.6 trillion won research and development plan includes the “graphite bomb,” also known as a “blackout bomb” or “soft bomb.” Using fine carbon filaments over electrical compounds, the nonlethal weapon is used to disrupt the enemy’s electrical supply.

Its key technologies will be developed by the ministry-affiliated Agency for Defense Development, and will be deployed in the field by the early 2020s, the ministry said.

Another segment of the new plan is introducing the enhanced antiballistic early-warning radar against the North’s submarine-launched ballistic missiles. South Korea believes the North will be able to deploy a SLBM within the next three or four years.

Seoul’s surveillance system currently includes two ground-based Green Pine radar units to detect upon a launch, then track and calculate the estimated location of its fall. Officials said the new radar will work on a similar principal, but have substantially improved functions.

The military also said it has changed the required operational characteristics for its radars to detect smaller drones from North Korea.
