UK Defence Journal

In 2016, the website published photos of all of 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 video game War Thunder.

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

In June 2025, the UK Defence Journal was the first outlet to report that a number of anonymous X accounts promoting Scottish independence had ceased posting during a widespread internet outage in Iran following Israeli air strikes. The UK Defence Journal article noted that the timing of the inactivity aligned with patterns previously associated with coordinated online influence activity, referencing earlier research by the disinformation analysis firm Cyabra.

The reporting was subsequently cited by national media outlets, contributing to wider coverage of alleged Iranian-linked online activity connected to Scottish independence discourse. The coverage also prompted calls from politicians for investigations into potential foreign interference in UK politics.
