ISYS Integral Systems, Inc. (MM)

Integral Systems, Inc. (Nasdaq:ISYS) announced today that the U.S. Air Force (USAF) Space and Missile Systems Center (SMC) has awarded the Company a $13.7 million contract modification to its Command and Control System-Consolidated (CCS-C) contract. Under the terms of the contract modification, Integral Systems will continue to provide the USAF and SMC with its EPOCH Integrated Product Suite (IPS) to simplify operations by consolidating satellite ground systems.

The contract modification extends CCS-C system sustainment, hardware maintenance, software maintenance and operations support into Calendar Year 2011 and establishes a new option CLIN for continuing CCS-C system sustainment through Calendar Year 2012.

"The modification is a testament to the exceptional sustainment support delivered by Integral Systems to integrate the command and control systems of the USAF's mission critical MILSATCOM assets," said Larry Lind, CCS-C Senior Program Manager, Integral Systems. "In close partnership with the USAF, our skilled professionals ensure CCS-C's operational readiness to execute the MILSATCOM program mission."

The CCS-C contract, first awarded in early 2002, enables a unified Command and Control (C2) capability for the 50th Space Wing's complete family of MILSATCOM satellite programs. By employing standards-based systems and an open architecture approach, the 50th Space Wing efficiently and cost-effectively supports legacy, new and emerging satellite platforms and programs.

ABOUT COMMAND AND CONTROL SYSTEM–CONSOLIDATED (CCS-C)

CCS-C is currently configured to support MILSATCOM satellites across four systems: the Defense Satellite Communications System (DSCS), Milstar, Wideband Global SATCOM (WGS) and the AEHF system. CCS-C consists of high-specification, commercially-available computer servers and workstations running commercially-available TT&C software packages on a local area network-based client/server architecture.

CCS-C products are operational at the Air Education and Training Command, 533rd Training Squadron at Vandenberg AFB, Calif., the 14th Air Force, 50th Space Wing and the 3rd and 4th Space Operations Squadrons at Schriever AFB, Colo.
