Organisations developing cutting-edge space technologies have a new opportunity to secure government backing as UK Defence Innovation (UKDI) launches the latest phase of its innovation programme aimed at strengthening the United Kingdom’s defence and security capabilities in space.
Created in collaboration with the UK Space Agency (UKSA) and the Defence Science and Technology Laboratory (Dstl), the initiative, known as Space to Innovate: Delta Drop, is seeking breakthrough ideas that could play a critical role in future government and defence operations.
The competition offers up to £985,000 in funding for successful projects and follows a two-stage application process.
Building on Previous Success
The Delta Drop competition continues a programme that began with the launch of Space to Innovate: Alpha Drop in 2021.
Over the past several years, UKSA and Dstl have invested more than £4.2 million in 19 organisations, helping advance innovative technologies designed to strengthen the UK’s position in the increasingly important space domain.
Those earlier investments have supported the development of emerging capabilities intended to provide operational advantages in an environment where space is becoming increasingly significant for defence, communications and national security.
Focus on Technologies That Commercial Markets May Overlook
The latest funding round is intended to support technologies that are considered strategically important for government and defence but may struggle to attract investment through the commercial space sector alone.
Officials are encouraging proposals from businesses, researchers and academic institutions capable of delivering innovative solutions across three priority areas identified as essential for future resilience and operational effectiveness.
Three Priority Technology Challenges
The competition has been organised around three specific technology challenges.
The first challenge seeks solutions that can improve sensor-to-response capabilities, enhancing the speed and coverage of systems supporting Space Domain Awareness (SDA), Intelligence, Surveillance and Reconnaissance (ISR), as well as communications missions.
The second challenge is focused on developing self-protecting technologies for space-based platforms, enabling satellites and other orbital assets to better defend themselves against evolving threats.
The third challenge looks for innovations that improve resilience against ground-based electromagnetic threats, helping safeguard critical space infrastructure from interference or disruption.
Funding Available for Mid-Stage Technology Development
Successful applicants will compete for a share of funding worth up to £985,000, with projects expected to run for as long as 18 months.
The programme is aimed at technologies currently between Technology Readiness Levels (TRL) 3 and 6, supporting concepts that have moved beyond early research but still require further development before deployment.
The competition will be conducted in two phases, with Stage One submissions due by 28 July 2026, followed by Stage Two applications, which must be submitted by 25 August 2026.
Responding to Growing Defence Needs in Space
According to the programme organisers, the competition reflects the UK’s expanding activities in the space sector and the corresponding need for more advanced technologies to support defence and national security missions.
Future capabilities will require improvements in the collection, processing and transmission of critical data while ensuring that space systems remain operational despite increasingly sophisticated threats.
By engaging industry and academia, the initiative aims to accelerate innovation that can address these evolving operational demands.
Information Sessions Planned for Interested Applicants
To help prospective applicants understand the competition requirements, organisers have scheduled a launch webinar on 8 July 2026.
The online event will explain the competition objectives in greater detail and allow participants to raise questions in an open discussion.
A series of 15-minute confidential one-to-one teleconference sessions will follow on 9 July 2026, giving organisations the opportunity to discuss technical aspects of their proposals directly with the competition team.
Registration for these sessions will open immediately after the webinar.
Invitation for Innovators to Submit Proposals
UKDI is encouraging companies, researchers and academic institutions with innovative technologies capable of enhancing future defence and security space capabilities to submit proposals.
Applicants are advised to review the full competition guidance before completing their submissions, ensuring that proposed projects align with the programme’s technical objectives and eligibility requirements.
