It is the fourth edition. The organisers describe it as a free event run by the space and defence community, open to government, industry, institutions and academia, with more than twenty talks across the two days and support for the Allied Forces Foundation. The programme covers military satellite communications, space-based intelligence, surveillance and reconnaissance, Earth observation and geospatial intelligence, space domain awareness, satellite navigation, space security and cyber, and national space programmes. ## Why a free defence space conference is unusual The defence space calendar is dominated by commercial conference organisers charging three to four thousand pounds for an industry pass. That model works: it funds a well-run programme and it filters the room down to people with a budget. It also filters out a great deal of the technical population, junior military staff, smaller suppliers and academic researchers, none of whom have a conference line in their budget. Defence in Space runs the opposite model. Admission is free, the funding comes from sponsors, and the result is a different room: more practitioners, more early-stage companies, more academics. That is a real trade-off rather than a straight improvement. What a free event does not offer is the closed-door procurement briefing that a paid conference can promise, because the attendance list is not vetted the same way. ## What the programme covers The published themes are the full military space stack. Military satellite communications and the growing use of commercial capacity for defence traffic. Space-based intelligence, surveillance and reconnaissance, with Earth observation and geospatial intelligence treated together. Space domain awareness and the tracking of objects and behaviour in orbit. Satellite navigation and the resilience of position, navigation and timing under jamming and spoofing. Space security and cyber, covering the ground and link segments as attack surfaces. And national space programmes, where individual countries set out what they are building. ## Who attends - Armed forces and space commands - Defence ministries and national security staff - Space agencies with a defence remit - Defence primes and space systems suppliers - Satellite operators selling capacity into government - Academic and research institutions working on space security ## FAQ · Identity and audience ### Is it really free? Yes. The organisers state plainly that it is a free event run by the space and defence community. Registration is still required. ### Who runs it? It is community organised rather than owned by a commercial conference company, which is why the branding is the event name itself. The event supports the Allied Forces Foundation. ### Is it classified or restricted? No. It is an open conference for government, industry, institutions and academia. Speakers at open defence events keep their material at an unclassified level, which is worth knowing if you are expecting operational detail. ## The venue: The Brewery The Brewery on Chiswell Street sits on the edge of the City of London, a converted 18th-century brewery now used as a conference venue. It is a mid-sized space, which fits an event of this scale, and it is a short walk from Moorgate, Barbican and Liverpool Street. --- ## Editorial take *A defence space conference that costs nothing to attend, which is why the room holds practitioners rather than the people who could expense a four-figure pass.* ## How to register and what it costs Attendance is free. Registration is handled through the official website, which also carries the schedule and the speaker list. Because there is no price barrier, popular editions of free conferences fill their capacity well before the date, so registering early is the practical advice rather than an upsell. Sponsorship and exhibition positions are arranged directly with the organisers and are how the event is funded. ## FAQ · Access and practicalities ### When and where does the 2026 edition take place? 27 and 28 October 2026 at The Brewery, 52 Chiswell Street, London. ### How much does it cost? Nothing. Attendance is free, though registration is required. ### How do I get to The Brewery? It is a five to ten minute walk from Moorgate, Barbican and Old Street Underground stations, and about fifteen minutes from Liverpool Street, which puts it within reach of Stansted Express and Elizabeth line arrivals. ### Are the talks recorded? The organisers do not publish a replay commitment. Attend in person if the content matters to you. ## Resources | Resource | URL | |---|---| | Official website | https://defenceinspace.com/ | | Schedule | https://defenceinspace.com/schedule/ | --- **Last verified:** 2026-08-03 **Next review:** 2026-10-01 **Notes:** The organisers publish no attendance figures; the counters on the event site were unpopulated at the verification date.
