Engineering is our passion.
Aerospace Design Ltd, trading as ADL UK, is an established British defence SME specialising in high-integrity systems engineering. Small by design, senior by experience, and independent by principle.
A British defence SME, built on first principles.
ADL is an established British defence SME specialising in high-integrity systems engineering. We have supported DE&S, Front Line Commands and defence primes across the land, air, sea, space and weapons domains, underpinning major operations and flagship programmes. ADL is also a proven Futures Lab lead organisation, collaborating with academia and manufacturing entities.
For over a decade we have engineered high-integrity, safety- and security-critical systems for the Ministry of Defence, including DE&S and the Submarine Delivery Agency, with particular depth in subsea platform systems, complex digital control and instrumentation, and integrated full electric propulsion.
Backed by over 150 years of combined defence engineering experience across air, land, sea and space, and a network of specialist partners including naval engineers, we offer independent technical assurance for safety- and security-significant digital systems: the kind a duty holder, a regulator or a design authority can rely on.
We are a micro-SME by headcount and deliberately so. The people who write the bid are the people who do the work, and every engineer on the team leads their own discipline.
Established processes don’t fit every challenge.
Recognising that established processes do not fit every development challenge, we apply first-principles judgement, experience and innovative thinking to reach the right outcome, without compromising on safety, compliance or assurance.
- First principles before precedentWe start from the physics, the hazard and the user need, then choose the process that fits, rather than forcing the problem into a template.
- The whole lifecycle, not one phaseConcept, Assessment, Demonstration, Manufacture, In-Service and Disposal. We have worked every stage of CADMID, so we design for the ones that come later.
- Independent, and accountable for itOur value to a customer is an opinion they can trust. We say what the evidence supports, and we put our name to it.
Led by engineers who have delivered.
