Halo: Warfleet – An Illustrated Guide to the Spacecraft of Halo

Halo: Warfleet – An Illustrated Guide to the Spacecraft of Halo is a reference book on the Halo universe that was released on September 5, 2017. The book details the technology, scale, design, construction, and variety of ships, space stations, and colony worlds in the Halo universe.

Content
Described as a more "technical" counterpart to Halo Mythos, Halo: Warfleet features ten full-color cross-sections of ships by Hans Jenssen, known for his work on Star Wars: Incredible Cross-Sections, and John Mullaney, who previously worked on ship cross-sections based on the Firefly franchise. In addition, multiple all-new secondary art pieces by various artists are included. Written by 343 Industries' internal writing team, with Kenneth Peters serving as writing lead, Warfleet also includes a variety of specific technical details and terminology formerly contained to the Halo Story Bible.

The book is divided into five sections: Introduction/Technical Architecture, Human Ships, Covenant Ships, Forerunner Ships, as well as an expansive Glossary. The book is published in an "oversized" format to accommodate the detail in the larger illustrations. Each spread includes annotations to explain the functions of given parts of a ship, along with statistics and history of the vehicle in question.

Development
Halo: Warfleet was announced on the Halo website in an issue of the Halo Community Update on October 14, 2016. On January 18, 2018, Jeff Easterling and Kenneth Peters promoted the book with a lore stream, discussing the book's development and providing more insight into some of the ships featured.
