UK Defence Journal

The UK Defence Journal is a website covering defence industry news in the United Kingdom. In addition to news content, the site also offers commentary and analysis of military topics ranging from national security policy to procurement decisions. The website previously published a monthly magazine of the same name containing news and analysis about the British Armed Forces.

Reporting
In 2016 the website published photos of all the Royal Navy's Type 45 Destroyer fleet in port at the same time which prompted Sky News to investigate Britain’s naval preparedness.

In July 2021, the website reported that a user leaked classified documents relating to the Challenger 2 Main Battle Tank in service with the British Army when challenging the representation of the vehicle in the videogame War Thunder.

In August 2022, the website was the first to break the news about the breakdown of HMS Prince of Wales, a British aircraft carrier, on the first day of the ship's deployment to the United States.
