See N.K. Ballistic Missiles 3D Models

North Korea possesses significant ballistic missile capabilities, and since the collapse of the Soviet Union has been one of the most active exporters of complete ballistic missile systems, components, and technology. Pyongyang received foreign assistance over the years, most notably from the Former Soviet Union and China, but the complete details of all foreign assistance remain vague. Considering North Korea's long-standing interest in advancing its missile capabilities, its missile program is notable in that there have been relatively few flight tests. U.S. sources estimate that North Korea has deployed over 600 Scud missile variants, about 200 Nodong (Rodong) missiles, and fewer than 50 Musudan and Taepodong missiles, while South Korean sources estimate even fewer. [1]

North Korea sees missile development as both an investment in its security and a means of generating cash. It is neither a member of the Missile Technology Control Regime (MTCR) nor the Hague Code of Conduct against Ballistic Missile Proliferation (HCOC). However, North Korea claimed membership in the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space including the Moon and Other Celestial Bodies and the Convention on Registration of Objects Launched into Outer Space in advance of the launch of the Unha-3 SLV in an attempt to "contribute to promoting international confidence." [2] Nonetheless, the UN Security Council condemned the initial launch and all launches since, as many saw them as veiled tests of North Korea's illicit ICBM efforts. [3]

History

North Korea first entered the field of rockets and missiles in the early 1960s with the production of multiple rocket launchers. [4] By 1965, Kim Il Sung made the political decision to seek an indigenous ballistic missile production capability. That year marked the establishment of the Hamhung Military Academy, where North Korean personnel began to receive training in missile development. [5] In general, the 1960s marked the procurement of rockets, surface-to-air missiles (SAMs), anti-ship missiles, and the initial development of human resources to support a missile program. By 1967-71, DPRK’s military budget increased to about 30 percent of its state budget. [6]

There were a number of factors that likely motivated the North Korean leadership to acquire and develop ballistic missile capabilities. First, Kim Il Sung viewed ballistic missiles as weapons to deter or defeat U.S. military forces in a subsequent conflict. Second, rocky alliance relationships with both the Soviet Union and China caused Kim to question the credibility of Moscow's and Beijing's commitments to aid Pyongyang in the event of another war. [7]

Early Ballistic Missile Developments

During the late 1960s, Pyongyang acquired surface-to-ship missiles and FROG-5/7 rockets from Moscow, [8] and by 1970, Beijing was delivering surface-to-ship missiles, SAMs, and technical assistance. [9] Although North Korea sought to acquire Soviet ballistic missiles as early as the mid-1960s, Moscow declined, at least initially, so Pyongyang turned to Beijing for help to produce ballistic missiles. In September 1971, North Korea signed an agreement with China to acquire, develop, and produce ballistic missiles and other weapon systems. However, substantial cooperation did not begin until about 1977, when Korean engineers were able to participate in a joint program to develop China's DF-61. [10]

The development of North Korean human resources was necessary, but not sufficient for the relatively rapid progress in Pyongyang's missile development program. North Korea has relied upon the transfer of hardware and technology from more advanced producers. North Korea obtained Soviet-made Scud-B missiles to begin a reverse-engineering program, but the timing and source of the procurement are still unclear— possibly as early as 1972 from the USSR. [11] However, the general view is that Egypt provided the first Scud-Bs to North Korea in 1976, or at some time between 1979 and 1981. [12]

By 1984, North Korea had produced and flight-tested the Hwasong-5, an indigenous version of the Scud-B, and in 1985 Pyongyang reached an agreement with Tehran to obtain financial assistance for missile development and production in exchange for Iran's option to purchase North Korean missiles in the future. [13] Iran's ballistic missile "war of the cities" with Iraq created an opportunity for North Korea to earn foreign exchange and increase scale economies in production. Furthermore, Tehran's use of the Hwasong-5 provided Pyongyang with performance data that would otherwise have required extensive indigenous flight-testing.

From 1985 to 1986, North Korea began to construct missile bases for the Hwasong-5, which entered serial production by 1987. It is believed production rate peaked at eight to ten missiles per month during 1987 to 1988. [14] As soon as or shortly after mass production of the Hwasong-5 began, North Korea began development of the Hwasong-6 (Scud-C), before rapidly starting the Nodong development program around the 1987 to 1989 timeframe. [15] This prompt sequence of development is remarkable, and historically unprecedented for a small developing country. Late-industrializing countries can reduce the time required for industrialization, and the same is true in the area of missiles. However, accelerated development is generally a function of foreign technology transfers, so Pyongyang's extremely rapid progress in missile development suggests a high level of foreign technical assistance.

By the late 1980s, North Korea began construction of intermediate-range missiles that were still under development. Around 1990 to 1991, serial production of the Hwasong-6 began, at about the same time the first Nodong prototypes were built. [16] Meanwhile, Pyongyang began to provide technology transfers, and even turnkey Scud factories, to countries in the Middle East.

Intermediate-Range Missile Development

In the late 1980s, North Korea's Second Natural Science Institute began development of the so-called "Nodong" intermediate-range ballistic missile. U.S. reconnaissance satellites detected a Nodong missile on the launch pad at the Musudan-ri missile test site in May 1990, but subsequent imagery revealed burn marks on the pad, which indicated a probable test failure. [17] Nevertheless, North Korea reportedly was able to obtain Nodong sales contracts with Libya, Iran, and possibly Syria and Pakistan before the Nodong was successfully flight-tested in late May 1993. [18] Although the Nodong was later flight-tested in Iran and Pakistan, the 1993 flight test is still Pyongyang's only indigenous test. It is worth noting that North Korea was unable to test the Nodong to its full intended range for geographic reasons. Nevertheless, Pyongyang began to deploy the Nodong in 1995. [19]

As North Korea was nearing completion of the Nodong's development, engineers were also working on the Taepodong-1. The Taepodong-1 does not have a new airframe or engine design, but is a two-stage missile with a Nodong as the first stage and Hwasong (Scud) variant as the second stage. [20] The Taepodong-1 was flight-tested in a space launch configuration on August 31, 1998, but did not place a small satellite named Kwangmyongsong-1 into earth orbit due to the failure of its third stage. [21]

North Korea's missile exports have represented a significant source of hard currency for Pyongyang. On December 10, 2002, Spanish and U.S. naval ships intercepted the North Korean ship So San en route to Yemen. The So San cargo included 15 Scud missiles, conventional warheads, and 85 drums of "inhibited red fuming nitric acid," which is used as an oxidizer for Scud missile fuel. North Korea declared the interception of the So San an "act of piracy" and demanded "compensation for the losses and personal trauma experienced by the crew members." The So San was ultimately permitted to deliver the Scuds, which were purchased by the Yemeni army for its own defensive use and therefore did not break international law at that time. [22]

In 2003, U.S. satellite imagery showed a new ballistic missile under development known as the Musudan that appears to be based upon the Soviet R-27 (SS-N-6). The R-27 is a liquid-fueled submarine-launched ballistic missile with a range of at least 2,500km. The land-based Musudan is 12 meters long and 1.5 meters in diameter with a range of 2,500-4,000km, although it has never been flight tested in North Korea. [23] The Musudan was displayed for the first time in 2007, though no images were shared by Pyongyang. It later made its debut in front of Western press (alongside Kim Jong Un, who also made his own international press-debut) in October 2010. The October parade was also notable for unveiling a new Nodong variant, about which little is known. The variant has a triconic nose-cone which greatly resembles Iran's Ghader-1 missile, perhaps hinting at further cooperation. [24]

Intercontinental Missile Development

In the mid-1990s, North Korea began design and development of the three-stage Taepodong-2. The first stage may use four Nodong engines, while the second stage could be based on a Nodong design as well. [25] Despite the lack of success in its flight testing, U.S. intelligence sources have consistently asserted that a functional Taepodong-2 could deliver a small payload to the western part of the continental United States. [26]

In July 2006, North Korea flight-tested several ballistic missiles, including the long-range Taepodong-2. The Taepodong-2 failed at about 40-42 seconds.[27] The North Korean Foreign Ministry referred to the July launches as "regular military drills to strengthen self-defense," and claimed it had a legal right to "continue with missile launch drills." [28] However, on July 15, 2006, the United Nations Security Council (UNSC) unanimously adopted Resolution 1695, which demands that North Korea suspend all missile-related activities and requires all UN member states to prevent the transfer of missile-related materials and technologies to North Korea. [29]

On April 5, 2009, North Korea launched an Unha-2 space launch vehicle—which is a modified version of the Taepodong-2. [30] Although North Korean media immediately claimed that the satellite had been placed into orbit, no orbit was detected by outside observers. The launch of the three-stage rocket was seen as a technical failure with the first stage splashing down in the water between the Korean peninsula and Japan, and the remaining stages, along with the payload, falling into the Pacific Ocean. [31]

In 2011, North Korea completed a 10-year initial construction project at the Sohae Satellite Launching Station. [32] The new base included a movable launch pad and a gantry tower which exceeds the needs of North Korea's largest ballistic missiles and space launch vehicles. The base is comprised of several missile assembly and testing structures, a launch warehouse, an observation tower, and a rocket engine test pad. [33] The site far outpaces North Korea's Tonghae facility near Musudan-ri, where it has tested short-range, medium-range, and intercontinental missiles. North Korea has since used Sohae to launch the Unha-3 rocket, and possibly test the engine of KN-08 missiles. [34]

The United States and North Korea pursued talks in February 2012, which culminated in North Korea's announcement that it would suspend long-range missile tests, along with uranium enrichment and nuclear tests. [35] However, on April 12, 2012 North Korea attempted to launch a satellite into orbit to mark the 100th anniversary of Kim Il Sung's birth using an Unha-3 rocket. The launch failed in seconds. [36] Because of the dual-use nature of missile technology, the United States considered this space launch a violation of North Korea's pledge that it would not test long-range missiles, and withdrew its offer of food aid. Three days later, Pyongyang held a parade in honor of its founding father Kim Il Sung, which purported to display a new missile system known externally as the KN-08. The missiles are most likely only mock-ups. [37] The KN-08s were displayed on six trucks of Chinese origin which had been converted to transporter-erector-launchers. [38] In October 2015, North Korea unveiled a new version of the KN-08 with a smaller, less conical warhead. [39]

On December 12, 2012, North Korea re-tested its Unha-3 rocket from the Sohae launch facility, successfully putting a satellite into orbit. [40] While North Korea refers to its rocket as a space launch vehicle, the technology is very similar to that of a long-range missile. In order to deliver a nuclear payload, the rocket would require the addition of a re-entry vehicle which requires technology and advanced materials experts believe North Korea does not currently possess. However, on March 15, 2016, North Korea announced it had begun testing just such a re-entry vehicle. [41] In February 2013, North Korea declared it had miniaturized a nuclear warhead, although it has not been definitively demonstrated to the outside world. [42]

Recent Developments and Current Status

North Korea has been working to improve its existing missiles and augment their capabilities. On March 9, 2015, North Korea released photographs showing Kim Jong Un in front of, what it claimed, was a miniaturized implosion-type nuclear weapon capable of fitting on the end of a missile. [43] In that same month, North Korea also released photographs appearing to show a successful test of a heat shield for a re-entry vehicle. [44] On April 9, 2016, North Korea announced it had tested a new type of ICBM engine. [45] Accurate details on the engine's capabilities are scarce; North Korea has only claimed that the new engine brings the U.S. mainland within range of its missiles. [46] Experts speculate that the engine might be a 4D10 engine, a sophisticated missile engine that was used in the SS-N-6 Soviet ballistic missile, if true this actually would bring most of the United States into North Korean missile range. [47]

These advancements have also been accompanied by upgrades to infrastructure and an increase in testing. The Sohae Satellite Launching Station, officially completed in 2011, has undergone significant additional construction since 2013. An eleventh level was added to the gantry tower, making room for rockets up to fifty meters in length; two new storehouses were completed, effectively doubling the storage capacity for rocket fuel and oxidizer; and an underground rail spur and moveable processing structure were added, making it increasingly difficult for outsiders to detect launch preparations. [48] This facility has become the regime's workhorse for long-range missile tests. On February 7, 2016, North Korea used the facility to launch the Kwangmyongsong-4 satellite into Low Earth Orbit (LEO) using the Unha-3 rocket. [49] The launch triggered widespread international condemnation and, in conjunction with a January 2016 nuclear test, led to additional sanctions being leveled against North Korea. [50]

North Korea has also been developing submarine-launched ballistic missile capabilities. In July 2014, a new type of submarine was spotted at the Sinpo Shipyard with visible conning towers that might be used to house either ballistic or cruise missiles. [51] On May 10, 2015, North Korea released images of Kim Jong Un observing a test of a Polaris-1 (북극성-1) SLBM purportedly launched from a submerged submarine. Analysts; however, have since determined the images were falsified, and that the missile was actually launched from a submerged barge. [52]  On March 24, 2016, North Korea tested a solid-fueled rocket motor. [53] Solid-fueled missiles, in contrast to liquid-fueled missiles, are much more storable and stable. This key difference makes solid-fuel propellants ideal for use in ballistic missiles, and especially in SLBMs. On April 23, 2016, North Korea tested what experts believe was a solid-fueled SLBM. [54] Though the missile flew only 30 km, well below its expected range of 300 km, the test marked a significant advance in North Korea’s efforts to develop a solid-fueled SLBM, and represents a significant proliferation concern.
