MIAMI & BETHESDA, Md.--(BUSINESS WIRE)--March 6, 2001

COMSAT Mobile Communications (CMC), a business unit of Lockheed Martin Global Telecommunications (LMGT), today announced it has signed an agreement with Silversea Cruises, Limited extending CMC satellite communications service to the entire Silversea fleet, including the newest ship in the Silversea family, the Silver Whisper.

The agreement calls for CMC to continue to provide global voice and data communications for Silversea's fleet of ultra-luxury, all-suite cruise ships. (See CMC Press Release July 5, 2000.)

COMSAT's C-Band satellite communications give the Silversea fleet one of the most advanced shipboard satellite communications solutions available today.

The satellite communications service will couple local and wide area networking with broadband technology to facilitate cost-effective and rapid transfer of large data files, while offering their guests and crew voice, e-mail, and a full range of Internet services.

CMC's complete package of voice and data services is scheduled for availability aboard the Silver Whisper for its July 2nd maiden voyage. Last year, CMC's C-Band service was installed aboard the 296-passenger Silver Cloud and sister ship Silver Wind, as well as the 382-passenger Silver Shadow.

"It is becoming increasingly important for people to stay connected in this fast paced global environment, and understanding this, Silversea is committed utilizing leading edge technology to provide its guests with the Internet and communications services they demand and deserve," said Irv Mednick, Silversea's vice president of information technology.

"CMC is committed to providing Silversea's guests and crew quality global communications, regardless of where they are cruising," said Kathryn Y. Holman, vice president and general manager of COMSAT Mobile Communications. "CMC's satellite communications services allow our maritime customers global access to the Internet, and the ability to respond to e-mails, download files and stay in touch with home, office, and friends."
