SSI Small Submersible
The North Korean maritime SOF threat is very real, substantial and dangerous. The CFC must intercept and destroy infiltrating maritime SOF elements to prevent them from reaching the ROK coastline and infiltrating into the ROK interior to disrupt CFC's rear operations. This is a challenging task because 86% of the ROK border is coastline, inundated with thousands of rocky islets, and is conducive to maritime infiltration operations by the North. The defense of the ROK is further complicated by the relative ease of access to its coastline from the sea and by the extraordinary size of the North's special purpose forces, the largest in the world.
North Korean naval forces have significant numbers of watercraft of various sizes and capabilities allocated exclusively to a maritime infiltration mission. These craft include a variety of submarines, coastal patrol craft, high-speed semi-submersible craft, air-cushioned amphibious craft, and rubber raiding craft.
The SILC is a high-speed semi-submersible craft that can be used to infiltrate North Korean Special Forces. North Korea has adapted technology to focus on invading the ROK; this boat is powered by three inboard-outboard engines and is capable of submerging for limited periods.
The North Koreans expect to use these craft to infiltrate large numbers of maritime SOF units into CFC rear areas just prior to hostilities, followed by a surge of other SOF and conventional maritime forces at the outset of a major offensive. These craft will transport SOF forces capable of sustained independent operations. They will gather intelligence, perform sabotage, and disrupt CFC's critical rear area activities supporting current and future operations. The North's SOF are capable of a wide variety of insurgent operations and terrorist activities. CFC expects them to attack utility systems, lines of communication and population centers.
