The launch of Atlantic Bastion marks a pivotal moment in the UK’s defence landscape. Positioned as a hub for cutting-edge technologies – AI, autonomy, cyber resilience, and advanced data systems – it signals a clear recognition that the future of defence capability will be defined not just by hardware, but by the intelligence, adaptability, and innovation embedded within it.

For SMEs and start-ups, this is more than a policy announcement – it’s an open door. The Ministry of Defence (MoD) is actively encouraging primes to collaborate with smaller businesses, recognising that such partnerships can create a more dynamic marketplace. By drawing on the agility, creativity, and technological edge that SMEs offer, primes can enhance their own capabilities while the MOD benefits from a richer, more innovative supply base.

The question is: how can smaller firms position themselves to compete in a market long dominated by the giants of defence manufacturing?

Why SMEs have the edge

• Agility over scale: Start-ups can pivot quickly, experiment with emerging technologies, and iterate faster than primes burdened by legacy systems.
• Deep tech specialism: SMEs often focus on niche areas such as AI algorithms, robotics and quantum computing. Areas that are precisely the capabilities programmes like Atlantic Bastion are seeking to harness.
• Collaborative culture: Smaller firms are naturally inclined to partner, co-develop, and integrate, making them ideal contributors to multi-domain solutions.
• Cost-effective delivery: Without the heavy overheads, bureaucratic layers, and legacy infrastructure of defence primes, SMEs can provide innovative solutions at lower cost, offering better value for money.

Competing to win

The primes will continue to dominate at a platform and hardware level, leveraging their vast financial resources, global supply chains, and manufacturing infrastructure to deliver the large-scale ships, aircraft, and vehicles that defence programmes demand. However, those platforms increasingly need digital overlays to make them smarter, more secure, autonomous, and resilient in a connected battlespace.

This is where SMEs have a clear opportunity: not to compete head‑on with primes, but to position themselves as essential enablers, providing the agile software, niche technologies, and cost‑effective innovation that transform traditional platforms into next‑generation capabilities.

Key strategies:

• Become indispensable partners: Frame your technology as the missing piece that primes need to future-proof their platforms.
• Leverage Atlantic Bastion’s ecosystem: Use the initiative’s collaborative framework to showcase solutions directly to MoD stakeholders and primes.
• Highlight dual-use innovation: Demonstrate how your technology has both defence and civilian applications, proving scalability and resilience.
• Emphasise social value partnerships: Show how collaboration with SMEs supports local economies, creates skilled jobs, and strengthens community impact — helping primes meet public sector social value requirements and enhance their procurement story.

Practical steps for SMEs

For SMEs aiming to secure a foothold in defence procurement, the ultimate goal is readiness to bid for (and win) MOD work. That readiness begins with compliance. Defence contracts demand rigorous standards, and firms that invest early in security accreditation, ethical AI frameworks, and robust supply chain assurance signal to both primes and the MOD that they are bid‑ready and capable of meeting contractual obligations.

Equally critical is the ability to tell a compelling story. SMEs should position their innovation not simply as a product, but as a capability that enhances national resilience. Embedding a strong social value narrative—demonstrating how projects support local economies, create skilled jobs, and strengthen communities—directly aligns with MOD procurement criteria and strengthens the case for contract readiness.

Collaboration also plays a vital role. By forming consortia with other SMEs, smaller firms can create the scale and credibility needed to compete for larger contracts, while retaining the agility that primes often lack. This collective approach not only enhances delivery capacity but also reassures evaluators that SMEs can meet the scope of MOD requirements.

Finally, SMEs should actively engage with MOD innovation pathways. Programmes such as the Defence and Security Accelerator (DASA) are designed to lower barriers to entry, offering SMEs a structured route to demonstrate capability, build relationships, and gain the experience that primes and government stakeholders look for when awarding new contracts.

Pete Coyle, Bid Masters CEO, said: “Through our work with SMEs across the UK, we hear time and again about the barriers they face in breaking into defence procurement – complex compliance requirements, prime-led supply chains, and the perception that scale always wins. Programmes like Atlantic Bastion should change that dynamic. This is a pivotal opportunity for SMEs not only to compete for contracts, but to redefine the marketplace and prove themselves as indispensable enablers of the UK’s future defence capability.”

Seizing the moment: SMEs as catalysts of defence innovation

Atlantic Bastion is not just about technology, it’s about sovereignty, resilience, and ensuring the UK remains at the forefront of defence innovation. SMEs and start-ups are uniquely placed to deliver the disruptive technologies that will define the next generation of defence capability.

The primes may build the platforms, but it is SMEs who will make them intelligent. The opportunity is clear: be bold, be collaborative, and position your technology as the brain behind the hardware.

For SMEs, Atlantic Bastion is not a challenge to break into a closed market, but rather an invitation to redefine it. The MoD has signalled that it wants innovation at the heart of defence. The firms that seize this moment will not only win contracts; they will shape the future of national security.
