On August 10, North Korea successfully test fired new short-range ballistic missiles (SRBMs) from Hamhung on the country’s east coast. According to South Korea’s Joint Chiefs of Staff, the two missiles flew 400 km and reached a 48 km apogee before landing in the Sea of Japan. Imagery released by North Korean media has suggested that the missiles are a new system, bearing a visual resemblance to the U.S.-developed ATACMS SRBM.
