Mars Type 7) is a single-stage, mobile liquid propellant medium-range ballistic missile developed by North Korea.

Developed in the mid-1980s, it is a scaled-up adaptation of the Soviet R-17 Elbrus missiles, more commonly known by its NATO reporting name "Scud".

United States reconnaissance satellites first detected this type in May 1990 at the Musudan-ri test launch facility, in northeastern North Korea.

[14] The precise capabilities and specifications of the missile are unknown; even the fact of its production and deployment are controversial.

[3] Its aerodynamic design is stable, reducing the need for modern active stabilization systems while the missile is flying in the denser lower atmosphere.

[11][18] Some press reports (including The Sunday Telegraph, Jerusalem Post, and Janes) claimed that Libya signed a contract for a total of 50 Nodong systems in October 1999, with the first batch delivered in July 2000, however such rumors proved to be false when Libya voluntarily dismantled its weapons of mass destruction programs in December 2003 and invited foreign inspectors to verify the disarmament process.

U.S. and South Korean Patriot PAC-2/3 interceptors are more specialized to hit ballistic missiles up to 400 km (250 mi).
