Janes Information Services

Janes is a global open-source intelligence company specialising in military, national security, aerospace and transport topics, whose name derives from British author Fred T. Jane.

History
Jane's Information Group was founded in 1898 by Fred T. Jane, who had begun sketching ships as an enthusiast naval artist while living in Portsmouth. This gradually developed into an encyclopedic knowledge, culminating in the publishing of All the World's Fighting Ships (1898). The company then gradually branched out into other areas of military expertise. The books and trade magazines published by the company are often considered the de facto public source of information on warfare and transportation systems.

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

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

Description
The company name is officially Jane's Information Group, and it is  located in Croydon. The company continues to provide open-source intelligence in the defence, security, aerospace and transport sectors.

Publications
