Jump to: navigation, search

HMS Invincible (SD-455) is an Invictus-class Pod-laying Superdreadnought within Battle Division 11 of Battle Squadron 1, assigned to Second Fleet. Commanded by CAPTSG Sir Jamey Salsberg, KDE, OC, RMN, Invincible's charter city is Minneapolis, Minnesota. Invincible serves as the Flagship of Second Fleet.


Invincible was commissioned on 3 May 2013 under the command of CAPTSG Elisa Randall, by order of BuShips. The commissioning ceremony was held in the presence of David Weber in the TRMN party room at DemiCon.

Her crew was formerly assigned to the Reliant-class battlecruiser HMS Invincible and upgraded to this new vessel, at which time the battlecruiser bearing the same name was retired. Invincible's crew traces its lineage to HMS Merlin, which was the first ship launched in Second Fleet, and one of the earliest chapters in TRMN.

Invincible has lead the way with many "firsts" in TRMN, including being the first ship to have over 100 members on its roster, as well as the first to have a company-sized MarDet, and then the first to have a battalion-sized MarDet. Her crew participates with distinction in many TRMN operations, including MantiCon, CONvergence, and Marscon.
