North Korea Accelerates Arms Build

North Korea has begun mass production of attack drones while continuing to improve its ballistic missile capabilities, gains largely attributed to military cooperation with Russia, The New York Times reported. The newspaper said Moscow is supplying military developments to Pyongyang in return for soldiers, workers and weapons.

Military ties between the two nations resumed after Russia launched its full-scale invasion of Ukraine, and North Korea has been modernizing its armed forces and equipment with Russian assistance since then.

In early October, Pyongyang tested a tactical ballistic missile that it says can carry a nuclear payload. South Korea and Japan estimated that the missile flew about 700 km (430 miles), while North Korea claimed a range of 1,000 km (621 miles).

The NYT noted that Seoul usually answers such tests with short statements calling them provocative. This time, however, South Korea test-fired its own hypersonic ballistic missile for the first time, five days after the North's launch. President Lee Jae Myung observed the test, which the newspaper described as a sign that Seoul is increasingly uneasy about the rapid progress of North Korea's missile technology.

Part of that progress stems from access to Russian deployment data and feedback. Analyst Anton Ponomarenko said this has helped North Korea improve the accuracy and manoeuvrability of its weapons, making the threat to South Korea "more substantial".

Russia has also helped North Korea build its own unmanned systems and produce them in large numbers. The NYT wrote that Pyongyang has seen in Ukraine and the Middle East how inexpensive drones can overwhelm costly air defence systems. In a North Korean drill last month, a drone swarm attacked a target island while cruise and ballistic missiles hit it at the same time from different directions.

The newspaper argued that these evolving tactics will eventually force South Korea and its allies to redesign their air defences at exorbitant cost.

The report follows other recent accounts of the partnership. Bloomberg reported in September that Russia is using North Korean citizens to produce military drones, notably at facilities in Alabuga, Tatarstan, with up to 25,000 North Koreans believed to be working at Russian military plants. A North Korean missile forces unit, which could be equipped with 120 ballistic missiles and six launchers for strikes against Ukraine, has also begun deploying in western Russia.

Ukrainska Pravda previously reported that Russia asked North Korea in August to provide KN-30 ballistic missiles. In June 2026, North Korea announced tests of a modernised 240mm multiple-launch rocket system, a tactical ballistic missile and a 155mm long-range artillery shell.
