Also reported

Navigation-system electronics — Conflict Armament Research documented more than 290 non-domestic electronic components in the missile that hit Kharkiv on 2 January 2024, most of them in the navigation system; about 75% linked to US-incorporated companies, 16% to European and 9% to Asian ones, from 26 companies in eight countries and territories. Date codes ran 2021–2023, so the missile could not have been assembled before March 2023 source
Voltage converter — XP Power (UK) voltage converter produced in February 2023, found by Ukraine's Defence Intelligence (HUR) in KN-23/KN-24 debris source
Control electronics (supplier countries) — HUR's updated War&Sanctions entry lists foreign components from companies in China, the United States, Japan, the United Kingdom and Switzerland; an earlier list named 19 companies from seven countries source
Satellite-navigation receivers — Ukrainian defence-ministry engineers matched niches for satellite-navigation receivers in Kharkiv debris to photographs from North Korean missile factories, one of seven matching parameters source
Circuit boards and assembly — Ukraine's defence ministry describes soldering methods and component quality about 50 years behind modern standards, built around civilian-purpose parts likely obtained in breach of sanctions source
Nose thermal protection — Graphite-material fairing on the nose section plus a thermal protective coating, which the ministry calls a cheap substitute for modern thermal-protection materials source
Rocket motor — Single-stage solid-propellant motor roughly 1.5 times larger and longer than Russian counterparts for a similar range, per Ukraine's defence ministry; the nozzle-fastening bolt pattern matches North Korean factory photographs source
Gas-dynamic rudders (jet vanes) — Made of what Ukraine's Institute of Armaments and Military Equipment identified as a Russian grade-9 tungsten alloy, as relayed in a RUSI commentary by Oleksandr Danylyuk source
Motor case — Fuel-tank body steels identified as Russian grades (12Kh2NVFA to 23Kh2NVFA family) and markings conforming to Russian standard GOST 2.113-75, per the same Ukrainian analysis source
