Logistics Command was a division of the Royal Manticoran Navy, submitted to the Third Space Lord, responsible for the planning, administration, and operational aspects of the RMN's supply train. It controlled a fleet of freighters, ammunition ships, and repair ships. Some had military grade inertial compensators so they could accompany fleets on maneuver. Mobile repair ships could even exchange fusion bottles in the field, a very major evolution, as was done at Hancock Station when HMS Nike arrived on her maiden voyage under Captain Honor Harrington.

Ships of Logistics Command were assigned to every operational Fleet to provide the services necessary to keep them on station and performing their assignments. (HH7)

The Joint Navy Military Transport Command was a combination of Logistics Command and the Office of Supply. (Companion)
