Excalibur was co-developed by Raytheon, a U.S. guided missile producer, and BAE Systems Bofor of Sweden, as a longer-range alternative to conventional artillery shells, with GPS guidance for improved accuracy. Excalibur has a range of about 40 to 57 kilometers (25 to 35 miles).
A meeting chaired by Defense Minister Lee Jong-sup endorsed 380 billion won for the development of a new 130mm guided rocket system by 2033, according to the Defense Acquisition Program Administration (DAPA), a state arms procurement agency. The program is to develop a land-based variant of South Korea's Biryong 130mm guided rocket system to attack infiltrating enemy boats and coastal artillery.
Biryong is a fire-and-forget rocket system with automatic target capture and tracking capabilities and has a range of up to 20km. Compared to the anti-ship rocket for use aboard high-speed patrol boats, the new 130mm rocket system will be fired from a land-based mobile launch vehicle.
