Mitsubishi Heavy and Preferred Networks ally to build Japan-made AI for defense and critical infrastructure
MHI and Preferred Networks signed a business alliance on June 2 to jointly develop AI for defense and social infrastructure, pairing MHI's hardware and system integration with PFN's PLaMo foundation models and MN-Core processors — with a capital tie-up targeted inside FY2026. The alliance is an explicit response to Japan's concern over foreign AI supply-chain dependence, marking the formation of a domestic AI stack inside Japan's defense-industrial sector.
