On 4 November 2025, London played host to Defence Disrupted 2025 , a one-day conference uniting military leaders, technologists, investors, and defence innovators.

Held on 28–29 October, the Defence in Space 2025 conference brought together defence leaders, space industry pioneers, and policy strategists in London for two days of discussion about the shifting realities of military operations beyond Earth’s atmosphere.

Held in a Creative Hub, the Defence Hack Day run by the team at European Defense Tech Hub (EDTH), staged as part of Estonian Defence Week and the wider Defence Expo, carried the weight of something larger than a single-day event, where participants were challenged to address pressing problems drawn directly from current conflicts.

Taking place on 24–25 September in the Estonian capital, the Tallinn Defence Expo was the flagship event of the first Estonian Defence Week.

Defence & Security Equipment International (DSEI) 2025, held at ExCeL London from 9–12 September, stood as a landmark biennial gathering for the global defence and security sector.
