Who We Are
The HMS Medusa is a chapter of The Royal Manticoran Navy, the Official Honor Harrington Fan Association, based in San Francisco, CA. The crew of the Medusa joined TRMN from all walks of life. We work in the IT industry, health care, libraries, firefighting … all with a common interest in science fiction and David Weber’s Honorverse.
This crew began its life within the TRMN as Her Majesty’s Pinnace Roland-One, with the gracious and kind support of our friends aboard the destroyer, HMS Roland. We applied for and transferred our command to the battlecruiser Artemis in 2014.  We continued to serve aboard Artemis until we grew in size large enough to necessitate a larger vessel.  In November 2015, we transferred over to the superdreadnought, HMS Medusa.
Since our commissioning, Medusa has served within the Talbott Fleet (10th Naval District), which is an association of chapters residing along the Pacific coast of the United States (California, Nevada, Oregon, Washington, Idaho, British Columbia, Alaska, and Hawai’i). Medusa is a member of Task Group 91.1, which represents the state of California with six other units.
What We Do

HMS Medusa stands for many ideals, the foremost of which is to have frun! We love pursuing our passions in many fields of interest:

  • sharing our interest in the Honorverse novels of David Weber
  • cosplaying at local sci-fi conventions
  • playing tabletop and on-line games 
  • learning military history
  • attending ship’s meetings
  • learning and practicing amateur radio operations
  • visiting interesting places around the San Francisco Bay Area
  • visiting distant cities to meet up with other members of The Royal Manticoran Navy
As a group we’re here to help you succeed in pursuing your passion, so tell us how we can help and we’ll do our best. You can drop us a note to let us know that you’re interested in signing aboard Medusa.
