The Defence Horizon Journal (TDHJ) is an independent international platform for scholarship and informed debate on security and defence. It connects researchers, practitioners and military professionals, aiming to advance strategic thought and link academic analysis with professional practice. Its articles examine a broad range of contemporary issues, including artificial intelligence, military training and education, autonomous systems, cyber and cognitive warfare, deterrence, maritime security, geopolitics and national resilience.

The journal also publishes book reviews and special editions, offering readers different perspectives on defence history, policy and emerging strategic challenges. Alongside written research and commentary, TDHJ features a podcast and invites submissions from contributors. Institutions can obtain digital access to the journal’s special-edition issues, with searchable content, accessible display options, cross-platform compatibility, usage reports and MARC records; trial access and pricing information are available.

Readers can also subscribe to the newsletter for updates and support the journal’s mission through donations. Through these offerings, TDHJ provides a forum for exploring developments shaping security and defence and encourages dialogue across research and practice
