May 1 (Asia Today) -- North Korea has transferred missile technology to Iran over more than 40 years, evolving from early Scud missile supplies to capabilities approaching intercontinental ballistic missiles, while also helping build factories, underground facilities and naval systems, according to U.S. experts.

Bruce Bechtol made the assessment at the annual International Council on Korean Studies conference titled "Challenges of the U.S.-South Korea Alliance 2026," co-hosted in Washington by the Hudson Institute and the Committee for Human Rights in North Korea.

Bechtol, co-author of the book Rogue Allies: Iran and North Korea's Strategic Partnership, said Iran began acquiring Scud missiles in the early 1980s during the Iran-Iraq War. Initially supplied in limited numbers by Libya, Iran later established contact with North Korea and imported roughly 100 Scud missiles, which it used to strike Iraqi cities during what became known as the "War of the Cities."

He said Iran subsequently ordered an additional 200 to 250 Scud-C missiles and, with North Korean assistance, produced and upgraded them domestically. This led to the development of Iran's current short-range ballistic missile, the Qiam, which has an estimated range of about 800 kilometers.
