PRESS RELEASE

SCOTTSDALE, Ariz. General Dynamics C4 Systems is delivering 300 rugged Sectra' Edge Smartphones to the U.S. Air Force. For use by senior leadership at the air staff and major command levels, the Smartphones are part of a broader Air Force plan to integrate Secure Mobile Environment Portable Electronic Devices (SME-PED) like the Sectra Edge into its consolidated enterprise network. General Dynamics C4 Systems is a business unit of General Dynamics (NYSE: GD).

The Sectra Edge provides cyber security at the hip, said Mike Guzelian, vice president of Secure Voice and Data Products for General Dynamics C4 Systems. Air Force and civilian personnel will have cost-effective, secure access to classified and unclassified networks, even the Internet, from virtually anywhere in the world.

The Sectra Edge is the first SME-PED certified by the National Security Agency for classified voice and data, using wireless access to commercial WiFi and cellular networks that provide access to classified and unclassified government networks.

Since 2007, General Dynamics C4 Systems has delivered thousands of Sectra Edge Smartphones to U.S. government customers, including users at the Departments of Homeland Security and Defense. Similar to a commercial cell phone/personal digital assistant (PDA), the Sectra Edge is capable of synchronizing information with a users computer, enabling access to calendar, address book, calculator, notepad and other PDA capabilities.

Capable of operating on existing Global System for Mobile (GSM) communications and Code Division Multiple Access (CDMA) commercial cellular networks, the Sectra Edge is WiFi compatible as well. Interoperable with over 350,000 fielded Secure Communications Interoperability Protocol (SCIP) devices, the Sectra Edge provides secure data communications classified Secret and below and secure wireless voice communications classified Top Secret and below.

Utilizing the Suite B encryption algorithm, the Sectra Edge interfaces with the U.S. Department of Defense Public Key Infrastructure using the governments standard Common Access Card. Information stored in the Sectra Edge is also protected using data-at-rest encryption.

The Sectra Edge Smartphone was developed under the NSA Secure Mobile Environment-Portable Electronic Device program and is compliant with the Secure Communication Interoperability Protocol (SCIP); it provides secure interoperability with other SCIP devices, including the Secure Telephone Equipment (STE), Omni, QSec and existing Sectra phones and terminals. The Smartphone is also compliant with the High Assurance Internet Protocol Encryptor Interoperability Specification (HAIPE' IS) for interoperability with in-line encryption devices that secure information on the U.S. Governments Secret Internet Protocol Router Network (SIPRNet), including the widely deployed TACLANE' family of network encryptors.
