The story

Founded by Fred T. Jane in 1898.1

Janes was founded in 1898 by Fred T. Jane, who had begun sketching ships as a naval artist while living in Portsmouth. This culminated in the publication of Jane's All The World's Fighting Ships (1898). Janes gradually branched out into other areas of military expertise. The books and trade magazines published by the company have become the de facto source of public information on warfare and transportation systems.

Based in Greater London for most of its existence, the company was owned by the Thomson Corporation, the Woodbridge Company, and then IHS Markit, before being acquired by Montagu Private Equity in 2019.

In March 2022, Janes acquired Washington, D.C.-based RWR Advisory Group.
