Data at Rest (DaR) - 400 Obsolescence Resolution

OBJECTIVE:
The USAF E-3G AWACS provides worldwide response to situations requiring immediate and continuous on-scene command, control, and battle management using embedded real-time surveillance to support employment of U.S. and allied combat forces. The E-3G consists of the air vehicle, sensor systems, and computing and communications equipment. The current USAF E-3G operational fleet consists of 15 operational aircraft. The E-3G DAR-400 (part numbers 63-2824652-01 through -03) is a mission 
critical asset and is in critical need of obsolescence resolution to prevent mission impact. Since the DAR-400 contains encrypted MCS, MSS, IPEC and GS data, a failure would directly impact operations and data security. General Dynamics Mission Systems (GDMS) has notified us that the DAR-400 will not be able to support or upgrade to changing NSA requirements.

SCOPE:
To execute the installation and integration of the obsolescence resolution for the mission-critical E-3G DAR-400 to prevent mission impact. The provided Government-owned KG-204 based solution is compliant with current DoD and NSA mandates to replace the legacy DAR-400 equipment.
