What is the Open Call

The Open Call competition is one of the competition mechanisms DASA uses to find proposals that address the challenges faced by defence and security stakeholders. It gives bidders the opportunity to present their ideas to defence and security stakeholders at any time and without waiting for a relevant Themed Competition.

What the Open Call seeks

The Open Call is looking for innovative ideas to improve the defence and/or security of the UK. Your idea could be a concept, technology, product or service, and bids are sought at various levels of maturity. Our Emerging Innovations category is for less mature innovations, and our Rapid Impact Innovations category is for innovations that are more developed.

Full details of this competition , including assessment methods and criteria, are contained in the Competition Document. View the Competition Document.

Additionally, we have published some Open Call innovation focus areas. This is to increase awareness of some of the enduring challenges faced by our defence and security customers, and to stimulate the submission of relevant innovative proposals. Read about the innovation focus areas here.

The Open Call for Innovation runs 6 cycles per year. Assessment starts the day after the competition cycle closing date.

A list of the cycle closing dates for 2018/2019 is below. Proposals must be submitted through the Accelerator Submission Service by midday on the closing date shown.
