Korea Aerospace Industries (KAI) and BAE Systems signed a contract agreement on 8 June to support delivery of the UK company's Archerfish Mine Neutralisation System (AMNS) for integration onto the KAI KUH-1 Surion mine-countermeasures helicopter (MCH).

The total number of AMNS units to be delivered to KAI under the agreement, which was signed at the MADEX 2023 exhibition held in Busan, is unknown. However, KAI intends to fit the MCH with four Archerfish systems and an associated launcher.

On 30 May the US Government Accountability Office (GAO) released a report about the Lockheed Martin F-35, finding that the programme has not adequately explained a cost increase of USD13.4 billion since 2019, that the upgraded Block 4 version has run into technical snags and a USD1 billion cost increase, and that the US Department of Defense (DoD) has not fully defined requirements for an engine cooling system upgrade.
