Airbus and Critical Software explore strategic partnership in embedded software development

Paris, 17 June 2025 – Airbus and Critical Software have signed a Letter of Intent to create a joint undertaking focused on the development of embedded software for aerospace applications.

The initiative aims to combine the companies' respective capabilities in designing and delivering safety-critical and certifiable software across multiple domains, including avionics, cabin and connectivity systems for current and future aircraft.

The objective is to secure long-term embedded software development expertise, aligned with the growing complexity and digitalisation of aerospace systems.

The potential new structure, which is subject to further assessment and regulatory approvals, would bring together Airbus’ aerospace expertise with Critical Software’s deep experience in embedded and safety-critical software engineering. 

"As embedded software becomes increasingly central to our products, securing the right expertise and capacity is key. This initiative reflects our intent to build robust, long-term capabilities in a highly specialised domain, relying on the world-class expertise of partners like Critical Software" said Sabine Klauke, Chief Technology Officer at Airbus.

“We’re proud to announce a new chapter in our collaboration with Airbus - one that reflects our shared ambition to shape the future of aerospace software. By combining our deep expertise in embedded and safety-critical systems with Airbus’ industry leadership, we aim to drive innovation where safety and reliability are paramount. Together, we’re committed to building a better, safer world.” said João Carreira, CEO at Critical Software.
