Hwasong-11 Family

The Hwasong-11 family refers to a series of short-range ballistic missiles (SRBMs) developed by the Democratic People’s Republic of Korea (North Korea). These missiles represent an important component of North Korea’s tactical missile arsenal and are regarded as a response to the missile capabilities of neighbouring states, particularly South Korea. The Hwasong-11 family is considered to be derived from the Soviet 9K79 Tochka (SS-21 Scarab) system, which was acquired in the 1990s, and has since undergone domestic modifications and advancements.

Background and Development

North Korea began pursuing short-range missile technology in the late 1980s and early 1990s, initially relying on imported Soviet and Chinese designs. The acquisition of the SS-21 Scarab technology provided the technical foundation for the development of the Hwasong-11 series.
Unlike earlier Scud-based systems, the Hwasong-11 family introduced solid-fuel propulsion, allowing for faster launch preparation, enhanced mobility, and greater survivability compared to liquid-fuelled missiles. These missiles are typically road-mobile, launched from transporter erector launchers (TELs), and designed for tactical battlefield use.
The Hwasong-11 missiles are part of North Korea’s strategy to deter adversaries and offset the conventional military superiority of South Korea and the United States. Their deployment increases North Korea’s ability to target military bases, infrastructure, and population centres within the Korean Peninsula.

Variants of the Hwasong-11 Family

Over time, North Korea has introduced several versions of the Hwasong-11, each with incremental improvements in range, accuracy, and payload capacity.

• Hwasong-11A
  • Believed to be a close derivative of the Soviet SS-21.
  • Estimated range: 120–140 km.
  • Solid-fuel propulsion, single warhead.
• Hwasong-11B
  • An improved model with enhanced guidance systems.
  • Range estimated at 200–250 km.
  • Capable of delivering conventional or potentially chemical warheads.
• KN-02 Toksa
  • A frequently cited designation for the Hwasong-11 series in Western defence literature.
  • Known for high manoeuvrability and relatively high accuracy compared to earlier Scud-based designs.
• Newer Extended-Range Variants
  • Since the late 2010s, North Korea has tested advanced SRBMs resembling Russian Iskander-M (9K720) systems, sometimes considered part of the broader Hwasong-11 family.
  • These include quasi-ballistic and manoeuvrable re-entry vehicle (MaRV) designs, complicating missile defence interception.
  • Estimated ranges vary between 400–700 km, allowing deeper penetration into South Korean territory.

Technical Characteristics

The Hwasong-11 family exhibits several technical features that distinguish it from earlier North Korean missiles:

• Solid propellant motors, enabling rapid launch capability.
• High mobility due to TEL-based deployment, enhancing survivability.
• Improved accuracy, particularly in later variants, through advanced guidance systems.
• Payload versatility, with options for conventional, chemical, or potentially nuclear warheads.
• Short flight times, making them difficult to intercept with existing missile defence systems such as South Korea’s Korean Air and Missile Defence (KAMD).

Strategic Role

The Hwasong-11 family serves both tactical and strategic functions within North Korea’s missile doctrine. Tactically, it can be used to target enemy troop concentrations, airfields, logistics hubs, and command centres. Strategically, it acts as part of North Korea’s layered deterrence strategy, complementing longer-range missiles aimed at the United States and Japan.
The deployment of advanced manoeuvrable variants poses a direct challenge to South Korea’s missile defence systems, raising concerns among regional security analysts. By fielding these missiles, North Korea seeks to increase its coercive leverage during crises and negotiations.

International Reactions

The development and deployment of the Hwasong-11 family have attracted international scrutiny. The United Nations Security Council has passed multiple resolutions prohibiting North Korea’s ballistic missile activities. Nonetheless, Pyongyang continues to conduct tests, presenting them as demonstrations of sovereign defence capabilities.
South Korea, the United States, and Japan view these missiles as destabilising factors in regional security. In response, they have strengthened joint military exercises, intelligence-sharing mechanisms, and missile defence cooperation. The resemblance of newer Hwasong-11 variants to the Russian Iskander-M has also raised suspicions of possible external technological transfers.

Significance

The Hwasong-11 family illustrates North Korea’s growing sophistication in missile technology, shifting from reliance on outdated Scud-type systems to modern, solid-fuel, manoeuvrable SRBMs. These missiles provide North Korea with flexible strike options and increase its capacity to challenge regional missile defences.
By integrating solid-fuel propulsion and manoeuvrable re-entry vehicles, the Hwasong-11 family underscores the continuing evolution of North Korea’s missile arsenal. Its tactical importance, combined with the potential for nuclear warhead integration, ensures that the system remains a central focus of regional security debates and non-proliferation efforts.
