Defence events in London

Best Defence is the most accessible entry point into Ontario's defence-industrial ecosystem — Canada's largest — offering direct, affordable face-time with CAF procurement officers, federal/provincial decision-makers, and prime contractors at a fraction of the cost of CANSEC or major trade shows. For SMEs and startups, the Technology Showcase provides a curated on-stage pitch opportunity directly in front of CAF and government buyers. The ODA's official backing adds institutional credibility and a growing member network, making it a high-ROI event for companies seeking Canadian programmes of record or teaming partners.

With European defence budgets at historic highs, programme and portfolio management professionals face acute pressure to deliver capability faster and with greater governance rigour — making this one of the few senior forums specifically dedicated to defence PPM execution rather than technology or procurement. The deliberately small delegate cap (80) means decision-makers — not mid-level attendees — fill the room, creating high-density networking with programme directors and PMO heads who control major delivery budgets. For PPM-tooling vendors, digital-engineering firms, and consulting SMEs, it is a rare access point to the European defence programme leadership tier without the noise of a large trade show.

Concentrated room of NATO end users and dual-use investors. For investors it is curated deal flow; for founders it is a warm introduction to alliance customers.

For defence SMEs and suppliers, IDS is one of the few niche forums where procurement decision-makers, programme offices (including DE&S and allied equivalents), and NATO representatives discuss active capability gaps and acquisition priorities in a small-group setting — making it highly efficient for business development and shaping bids. Co-location with the Uncrewed & Autonomous Systems conference in 2026 broadens the addressable audience to include the fast-growing autonomy and UAS procurement community. The early-bird deadline and tiered partnership packages make it accessible to smaller companies seeking thought-leadership or exhibition exposure alongside primes.

With 250+ senior defence, government, and industry representatives attending, this is one of the UK's most focused annual forums for UGV and UAS procurement discussions, making it a direct channel to British Army, NATO, and allied acquisition decision-makers. SMEs and technology startups can access dedicated exhibition and roundtable partnership slots that place emerging autonomous solutions in front of programme managers and capability developers. The co-location with International Dismounted Soldier amplifies cross-domain relevance for suppliers covering soldier systems, robotics, and human-machine teaming.

Soldier modernisation programs are recurring and broad. A focused venue for firms in wearables, power, optics and edge compute to reach program offices.

Multi-domain coverage and a strong UK/Commonwealth procurement presence make DSEI a primary BD event for firms targeting the UK MoD and allied buyers.
