311th Signal Command as the designated Signal command for the Army Service Component Commands within the Pacific and Korean theaters, the 311th Signal Command combines the strengths of more than 3000 active-duty soldiers, U.S. Army Reserve soldiers and Army civilians to bring expertise, experience and commitment to meet the Army's communications mission in the Pacific.[citation needed] Headquartered at Fort Shafter, Hawaii, the 311th SC and its subordinate units are stationed across 16 time zones, ranging from Alaska to Korea, and from Hawaii to California.

The mission of the 311th is to maintain and defend the Pacific LandWarNet (PLWN), a secure Army network used throughout the Pacific region. Serving as the operational Signal command for U.S. Army Pacific (USARPAC), the 311th SC takes the lead to ensure the PLWN can be extended to support the deployment and integration of modular, expeditionary Army units called to execute contingency operations within its Area of Responsibility (AOR).[citation needed]

In addition to providing support for USARPAC missions with critical planning and execution of signal support, the 311th SC makes continual improvements to the PLWN to remain ahead of and prepared to support the transformation efforts of USARPAC’s Major Subordinate Commands (MSCs) and its sister Theater Enabling Commands (TECs).[citation needed]

The 311th Signal Command also supports the Army Network Enterprise vision through its alignment with 9th Signal Command (Army)/NETCOM’s Global Network Enterprise objectives. Through this administrative command relationship, the 311th Signal Command ensures that the Army CIO/G6 and 9th Signal Command’s Army enterprise network standards are supported and implemented throughout the Pacific theater in order to establish a single global Army network enterprise.[citation needed]


The 311th Signal Command originated in 1944 as the 3112th Signal Service Battalion at Fort Monmouth, NJ, supporting Allied efforts during World War II. The 3112th participated in campaigns in Normandy, northern France, Rhineland, Ardennes-Alsace and central Europe. The 3112th Signal was reorganized multiple times until it became the 311th Signal Group in 1952 as part of the Organized Reserve Corps. Due to growing requirements within the Army, the 311th was identified to become a general officer, theater-level command with the subsequent designation as the 311th Signal Command (Theater) at Fort Meade, Md., in 1996. Ten years later, in September 2006, the 311th SC (T) was reorganized to become the 311th Signal Command and relocated to Fort Shafter, Hawaii, to become a theater enabling command of U.S. Army Pacific.

Reorganized to support modularization and transformation of the Army in the Pacific, the 311th Signal Command combines the strengths of active duty soldiers, a U.S. Army Reserve Command (USARC) component force and a team of civilian employees, to ensure secure communications throughout the theater.[citation needed]




The Pacific LandWarNet is the communications architecture for the U.S. Army Pacific AOR. It serves as the command and control information network throughout the Pacific theater. Pacific LandWarNet supports missions associated with the integration of strategic, operational and tactical communications, and data exchange requirements within the AOR. Pacific LandWarNet supports the operations of Joint, combined, and Army forces, supporting day-to-day operations. The network can be extended to enable forward stationed and CONUS-based military formations.
