Iridium Satellite Wednesday said that it has approximately 137,500 subscribers as of September 30, 2005. The new total represents a 22% increase over the total number of subscribers at the end of the third quarter last year. Revenue for the nine months ended September 30, 2005 was up 24% over the nine months ended September 30, 2004.

"Iridium added approximately 10,500 subscribers in the third quarter of 2005," said Carmen Lloyd, Chairman and Chief Executive Officer, Iridium Satellite. "Increased usage by first responders engaged in relief efforts in the U.S. Gulf Region in September contributed to our strongest quarter for subscriber growth and equipment sales."

Lloyd said, "Since our network does not rely on land-based infrastructure, Iridium was able to operate during the hurricanes when flooding and winds disabled conventional telephone and cellular systems, as well as radio systems, in Louisiana, Mississippi and Alabama. We are pleased to have played a key role for first responders during this crisis."

Third Quarter 2005 Highlights

As previously announced, in the first 72 hours of Hurricane Katrina, Iridium traffic in the Gulf Region increased more than 3,000%, while the number of subscribers in the affected areas increased more than 500%. To help meet this increased demand, the Federal Communications Commission (FCC) granted Iridium the use of additional spectrum to accommodate network traffic and minimize the risk of congestion.

Iridium also moved to an around-the-clock "24×7" manufacturing schedule to accommodate the surge in need for mobile satellite communications services.

During the quarter, Iridium and its partners shipped more than 13,300 voice and data units. This reflects some portion of the new activations in the third quarter, as well as units purchased for future activation.

The company also cited the following developments in its key vertical markets in the third quarter of 2005:

Defense/Government

In September, Iridium announced that the U.S. Air Force is completing the worldwide deployment of more than 280 tactical meteorological data collection systems. These systems will use the Iridium network to transmit near-real- time weather data to war planners and decision makers.

With an embedded Iridium data modem, these new systems represent an important improvement over legacy tactical weather systems. In the past, combat weather teams could need up to 72 hours to establish a deployed weather network. The Iridium-based systems allow the teams to start transmitting weather data from any location on the globe within an hour of arrival.

Aviation

In July, Iridium announced that the U.S. Forest Service (USFS) fitted 200 primarily contract aircraft with Iridium equipment for data and voice communications between the aircraft and the ground.

Part of the interagency Automated Flight-Following (AFF) program, the aircraft are mainly helicopters, and light and transport fixed-wing airtankers. They are used for wildland fire fighting and other natural resource agency missions.

Iridium noted that its aviation business has more than doubled over the last 12 months. The number of aircraft fitted with Iridium voice and data equipment has grown by more than 100%, while the number of aircraft with Iridium-based, data-only systems has increased 200%. The company's total number of subscribers in the aviation market now surpasses 5,000.
