J._Fred_T._Jane was quite a visionary of military technology.
"...An avid miniatures wargamer, Jane first published All the World's Fighting Ships (known as Jane's Fighting Ships after 1905) in 1898, which catalogued all the warships operated by each country, their armaments, and other details, as a supplement to a wargame he designed. It was a success from the start and has become the standard reference directory on the topic. The Naval Warrant Officer's Journal suggested that the book be on every ship, and in 1902 said that it should be available to every naval officer. The Admiralty were less enthusiastic, partly due to Jane's irreverent behaviour - although some ships did acquire copies.[2]
In 1909, he created All the World's Aircraft. Jane's firm is now Jane's Information Group.
Jane was an accomplished maritime and naval artist whose works were widely published in periodicals and his own books, those illustrations are now collectable." https://en.wikipedia.org/wiki/Fred_T._Jane#Biography
Janes_Information_Services is certainly at the top of their game. https://www.janes.com
