Navy Expeditionary Logistics Support Group (NAVELSG) is an enabler of Maritime Prepositioning Forces (MPF), Joint Logistics Over-the-Shore (JLOTS) operations, and maritime forces ashore, providing expeditionary cargo handling services for surface, air, and terminal operations, tactical fueling, and ordnance handling/reporting in support of worldwide Naval, Joint, inter-agency, and combined forces/organization.

NAVELSG is responsible for providing expeditionary logistic capabilities for the Navy, primarily within the maritime domain of the littorals, and conducts surface and air cargo handling missions, cargo terminal and warehouse operations, fuels distribution, postal services, customs inspections, ordnance reporting and handling, and expeditionary communications.

[10] More recently, the lessons learned from Operation Desert Storm identified a requirement for a single, multi-functional organization able to provide flexible, deployable transportation and supply support logistics services in any area of the world.

Established in 1993, the Naval Expeditionary Logistics Support Group (NAVELSG) was built upon the foundation of the Navy Cargo Handling Force (NCHF).

The NCHF originated in the 1970s with the establishment of six Reserve Navy Cargo Handling Battalions to support the Marine Corps Maritime Prepositioning Force.
