In 2015, I compiled the first edition of a resource document to support a presentation I made in August 2015 to The Lyncean Group of San Diego (www.lynceans.org) commemorating the 60^thanniversary of the world’s first “underway on nuclear power” by USS Nautilus on 17 January 1955.  That presentation to the Lyncean Group, “60 years of Marine Nuclear Power: 1955 –2015,” was my attempt to tell a complex story, starting from the early origins of the US Navy’s interest in marine nuclear propulsion in 1939, resetting the clock on 17 January 1955 with USS Nautilus’ historic first voyage, and then tracing the development and exploitation of marine nuclear power over the next 60 years in a remarkable variety of military and civilian vessels created by eight nations.

Here’s a quick overview of worldwide marine nuclear in 2018.

In July 2018, I finished a complete update of the resource document and changed the title to, “Marine Nuclear Power: 1939 –2018.”  Due to its present size (over 2,100 pages), the resource document now consists of the following parts, all formatted as slide presentations:

• Part 1: Introduction
• Part 2A: United States – Submarines
• Part 2B: United States – Surface Ships
• Part 3A: Russia – Submarines
• Part 3B: Russia – Surface Ships & Non-propulsion Marine Nuclear Applications
• Part 4: Europe & Canada
• Part 5: China, India, Japan and Other Nations
• Part 6: Arctic Operations

The original 2015 resource document and this updated set of documents were compiled from unclassified, open sources in the public domain.

I acknowledge the great amount of work done by others who have published material in print or posted information on the internet pertaining to international marine nuclear propulsion programs, naval and civilian nuclear powered vessels, naval weapons systems, and other marine nuclear applications.  My resource document contains a great deal of graphics from many sources.  Throughout the document, I have identified the sources for these graphics.
