IRGC Quds Force Unit 340 is an Iranian military technical unit, not a commercial defense contractor. The UK government described Unit 340 as responsible for research and development and for providing training and technical support to groups backed by Iran, while CTC Sentinel identified it as the IRGC-QF Technical Department associated with Houthi qualitative forces.
Defense-analysis sources describe Unit 340's work as part of a wider Quds Force method: transferring missile know-how, training, designs, and production processes so partner forces can build or adapt weapons locally. IISS reporting on Iran's missile proliferation cites leaked material that placed Unit 340 in the lead role for a Palestinian Islamic Jihad artillery-rocket effort that included the Badr-3 heavy rocket and related simple rocket designs optimized for proxy production.

Unit 340 is a secretive military element rather than a conventional commercial manufacturer, so public sourcing is indirect and mostly comes from sanctions notices and defense-analysis reporting. No reliable public headquarters address or rights-clear reusable image was verified for this profile, so both are omitted.
