Vic Sellier Promoted to Executive Vice President; Aaron Daniels Promoted to Chief Financial Officer

FAIRFAX, Va. -- Argon ST, Inc. (NASDAQ:STST), a leading developer of Command, Control, Communications, Computers, Combat Systems, Intelligence, Surveillance and Reconnaissance (C5ISR) systems, announced today that its Board of Directors has elected Vic Sellier as Executive Vice President and Aaron Daniels as Vice President, Chief Financial Officer and Treasurer effective November 27, 2007.

As Executive Vice President, Mr. Sellier will continue his prominent leadership role in driving Argon's growth initiatives as well as managing its corporate infrastructure, to assure the Company's continued satisfaction of the growing demands resulting from the government's recognition of Argon ST as a major contractor responsible for programs of national importance. This new focus will be aimed at providing the business managers of existing and newly acquired Argon ST operations with the tools and support to drive efficiencies while meeting the Company's growth and profitability objectives.

"Vic has played a significant role in our success to date," said Dr. Terry Collins, Chairman and Chief Executive Officer, Argon ST. "During the past 10 years, he has not only driven excellence in our support organizations but also played key roles in our process improvement and customer and capability expansion initiatives. His unique and diverse skill set makes him the perfect person to assume responsibility for supporting operational efficiencies, opportunistic teaming, M&A initiatives, and ongoing infrastructure integration activities. As we work toward a second consecutive year of record bookings and backlog, I anticipate that the addition of this function to our executive management team will prove to be central to our success."

"Aaron, who has been our Chief Accounting Officer since August 2006, is a natural fit for the CFO position," continued Dr. Collins. "He is a seasoned executive who brings strong experience in leading the finance operations of both large and rapidly growing corporations. In addition, he has spent the last year gaining a thorough understanding of our business. Aaron will assume responsibility for Sarbanes-Oxley compliance, financial management, planning, and reporting as well as investor relations. I am confident that Aaron will continue to drive our focus on building value for Argon shareholders and will maintain our commitment to financial excellence established under Vic's leadership."

Vic Sellier has been Chief Financial Officer and Treasurer for Argon ST since July of 2005. Mr. Sellier was one of the three founders of Argon Engineering in 1997. Prior to the formation of Argon Engineering Mr. Sellier served as Assistant General Manager from 1989 to 1997 at E-Systems/Raytheon.

Aaron Daniels has been Argon ST's Chief Accounting Officer since August 2006. Prior to joining the company, Mr. Daniels was the Senior Vice President and Corporate Treasurer at InPhonic, Inc. From 2000 through 2006, Mr. Daniels held various senior finance positions at InPhonic including Corporate Treasurer, Senior Vice President Finance of Liberty Wireless, Acting CFO and Vice President Finance and Corporate Controller.
