Design and development

In 1983, Syria acquired a number of 9K79 Tochka (SS-21 Scarab-A) missiles from the Soviet Union, a single-stage, solid-propellant guided missile with a range of 70 km and a CEP of 160 m. In 1996, Syrian missile technicians provided North Korea with technical data on the missiles, then shipped some of the missiles themselves. The first test of a North Korean-produced version occurred in April 2004 and was a failure, but it was then successfully fired on 1 May 2005 into the Sea of Japan; the KN-02 has been tested at least 17 times. Initial production is believed to have begun in 2006, with the missile displayed aboard a launcher during a military parade in April 2007, and entering service in 2008. At least 50 missiles are speculated to be in service.[6][7][8]

The KN-02 is a short-range, road-mobile ballistic missile, broadly equivalent to improved Scarab-B. Although it has a shorter range than other North Korean missiles like the Scud-C, it has superior accuracy of near 100 meters CEP through inertial guidance with an optical correlation system in the terminal phase, making it the most accurate ballistic missile in the inventory; this enables it to be used for precision strikes against priority targets such as airfields, command posts, bridges, storage facilities, and even enemy troops concentrations in a tactical support role on the battlefield. Its warhead weighs 485 kg (1,069 lb) and likely consists of a high-explosive, submunition, chemical, or biological payload; Russian engineers could equip the OTR-21 with a 100 kiloton nuclear warhead, but North Korea is not likely to be able to do the same. The missile has a range of 120–140 km (75–87 mi), and it may be capable of traveling 160 km (99 mi) through reducing payload to 250 kg (550 lb).[6][7][9][10]

A significant difference between the Russian OTR-21 and North Korean KN-02 is the transporter erector launcher (TEL). While the Russian missile is transported and fired from the 6×6 9P129 that has amphibious capabilities, the KN-02's TEL is a locally fabricated version of the Belarusian MAZ-630308-224 or -243 6×4 or 6×6 commercial heavy utility truck, which has a maximum road speed of 60 km/h (37 mph) and is not amphibious. The vehicle has a short firing cycle, able to be ready for launch in 16 minutes, launch the missile in 2 minutes, and be reloaded in 20 minutes by a supporting reloader vehicle of the same design fitted with a crane and holding 2-4 more missiles.[6][7][10][11][12][13]

Further developments

In 2013, South Korean intelligence reports suggested that North Korea was developing an anti-ship ballistic missile version of the KN-02. Its range is estimated to be 200–300 km (120–190 mi; 110–160 nmi), longer than current KN-01 variants, and it would be much more difficult to intercept due to its faster speed.[14]

In March 2014, a South Korean military source claimed that the KN-02's range had been extended to 170 km (110 mi) through improved engine performance. The source also claimed that North Korea possessed 100 missiles with 30 TELs deployed to fire them.[15] In August 2014, KN-02s were fired out to a range of 220 km (140 mi).[16]
