Diehl Defence and AEL Sistemas Sign MoU to Advance Brazil's Air Defense Capabilities
German defense manufacturer Diehl Defence and Brazilian firm AEL Sistemas formally signed a Memorandum of Understanding (MoU) on July 3, establishing a framework for cooperation on Brazil's medium- and extended-range ground-based air defense programs.
Clear Division of Roles
Under the terms of the agreement, Diehl Defence will act as prime contractor for the IRIS-T SLM medium-range surface-to-air missile system and is expected to lead future work on the extended-range IRIS-T SLX variant. As the local industrial partner, AEL Sistemas will be responsible for integrating Brazilian domestic technology components and delivering comprehensive in-country logistics and support services.
Government-Level Backing from Both Nations
In a press release issued on July 6, Diehl Defence highlighted the strong diplomatic foundation underpinning the partnership. In April 2026, German Chancellor Friedrich Merz and Brazilian President Luiz Inácio Lula da Silva signed a government-to-government MoU covering defense procurement cooperation during bilateral consultations held in Hanover — providing the political framework for this industry-level agreement.
Counter-UAS Market Context
The partnership comes amid growing global demand for integrated air defense solutions capable of addressing drone threats. The 2026 Unmanned Airspace Global Counter-UAS Systems Directory — the world's only continuously updated comprehensive directory of counter-UAS (C-UAS) companies and systems — has now been officially released. The directory catalogs more than 1,000 counter-drone products and services, including detailed performance specifications, commercial arrangements, and partnership structures. Entries are categorized by defeat method, including nets, missiles, interceptor drones, and detection sensors, and are updated on a monthly basis.
