About Ten Ballistic Missiles

A keyword referring to a group of short-range ballistic missiles that North Korea launched en masse into the East Sea in 2025, sparking debate over responses to saturation attacks.

About Ten Ballistic Missiles

Overview

"About ten ballistic missiles" is an expression referring to a group of short-range ballistic missiles (SRBMs) that North Korea launched from the Wonsan area into the East Sea in May 2025. As the South Korean Joint Chiefs of Staff announced the number of detected missiles as "around ten," the phrase became a key keyword for media and security analysts. Unlike North Korea's missile provocations, which had usually involved one or two missiles, this incident involved the scattering of nearly a double-digit number of missiles at once, prompting discussion about the Korean Peninsula's air defense system and its capacity to respond to mass saturation attacks.

Main Details

Launch Overview

  • Time: Morning of May 8, 2025
  • Launch area: Wonsan area, Kangwon Province
  • Direction and impact: East Sea
  • Type: Estimated to be short-range ballistic missiles (SRBMs). Many raised the possibility of 600mm-class super-large multiple rocket launchers (KN-25)
  • Scale: "Around ten" according to the Joint Chiefs of Staff count
  • Detection means: Early warning assets of South Korean and U.S. military authorities and combined ROK-U.S. intelligence, surveillance, and reconnaissance assets

South Korean and U.S. military authorities began work to identify the missile type by analyzing flight trajectory, range, altitude, etc. immediately after the launch, and Japan's Ministry of Defense also stated that it separately collected information through Self-Defense Force assets.

Meaning of the Number "Around Ten"

Single or small-number launches have a strong character as political signals, but a simultaneous launch of around ten missiles carries the military implication of an attempt at saturation of interception systems. Mass launches targeting the capital area and major bases have the character of testing the simultaneous response limits of multi-layered defense assets such as the Korean Air and Missile Defense (KAMD), Patriot, and Cheongung-II. In addition, "mixed launches" that mix multiple missiles with different ranges and altitudes are analyzed as a tactic intended to shorten decision-making time for detection, identification, and interception.

Missile Types and Technical Characteristics

The 600mm-class multiple rocket launcher called KN-25 is a system that North Korea promotes as a "super-large multiple rocket launcher," and it is assessed to reach a range of around 400 km. It combines satellite navigation guidance and terminal guidance functions, giving it higher accuracy than simple unguided rockets, and it is characterized by the ability to quickly evade after launch using a transporter erector launcher (TEL). However, because actual flight data differ with each launch, estimates of range and altitude sometimes vary among analysis organizations.

Political and Diplomatic Background

The timing of the launch was a period when complex factors overlapped, including the deployment of U.S. strategic assets, ROK-U.S. combined exercises, and deepening North Korea-Russia military cooperation. North Korea has usually responded to large-scale combined exercises or the deployment of U.S. strategic bombers with shows of force, and this launch was interpreted in the same context. Experts see the multiple launch as having the dual purpose of demonstrating external negotiating leverage while verifying the reliability of systems deployed in actual operations.

International Reactions and Assessments

The South Korean government immediately issued a statement of condemnation and said it would review whether the launch violated UN Security Council resolutions. The U.S. Department of State and the Japanese government also expressed their intention to respond jointly, saying it was an act that raised tensions on the Korean Peninsula. On the other hand, some analysts raised a cautious view that, given the short range and the impact in the East Sea, it was "close to a political signal."

Latest Trends

North Korea's missile activities in 2024–2025 are summarized as "multiple types, large quantities, and multiple directions." The practice of mixing and firing short-range ballistic missiles, cruise missiles, and multiple rocket launchers increased, and the tendency to greatly increase the number of projectiles in a single launch became clear. In response, the South Korean military is hurrying to expand the simultaneous processing capacity of detection and interception assets, introduce AI-based target identification, and adopt an integrated air defense concept with drones and unmanned aircraft. Since 2024, the possibility that North Korean systems' operational data could be provided to Russia through North Korea-Russia military cooperation has also emerged as a point of debate. In addition, mass launches such as "around ten" are being used as an indicator of what kind of saturation attack scenario North Korea is envisioning at the stage of practically operating nuclear and missile threats in the future.
