L3Harris has received a new contract to modernize the US Marine Corps’ satellite communications systems, strengthening frontline connectivity for distributed operations. The initiative will enhance data speeds and introduce access to multiple satellite orbits, aligning with the Corps’ Joint All-Domain Command and Control (JADC2) strategy for seamless multi-domain integration.
As part of the order, L3Harris will upgrade Panther 2 man-portable terminals and provide improved Ku-band transceivers capable of boosting power output to 25 watts. The Panther 2 terminal is a compact, tri-band SATCOM solution that can be deployed by a single Marine in fewer than ten minutes. Its modular design allows frequency-band swaps and antenna changes on the fly, offering significant operational flexibility during expeditionary missions.
Designed for compatibility with a wide range of military and commercial satellite constellations, the Panther 2 system features a fanless, passively cooled modem and can be operated through a web interface or front-panel controls. Optional power modules deliver backup power and battery charging capabilities. Depending on configuration, the terminal can be packed into one transport case and weighs between 63 and 74 pounds, with the lightest configuration under 34 pounds.
The effort is part of the Marine Corps Wideband Satellite – Expeditionary (MCWS-X) program, a next-generation portable SATCOM initiative that L3Harris has supported since 2020. MCWS-X delivers robust, multi-waveform, high-frequency communications designed for small, mobile units operating across dispersed battlefields. The system ensures reliable voice, data, and video connectivity while supporting the Corps’ transformation toward more agile and network-centric operations.
