Revenue at SpaceDev Inc. jumped 64 percent in 2004, though the companyโ€™s loss increased over 2003, SpaceDev reported March 29.

SpaceDev lost $3 million on revenue of $4.9 million in 2004, compared to a loss of $1.2 million on revenue of $3 million in 2003, the company said.

Jim Benson, SpaceDevโ€™s founding chairman and chief executive officer, credited the revenue growth to the companyโ€™s work for the U.S. Missile Defense Agency, the U.S. Air Force Research Laboratory and for Scaled Compositeโ€™s SpaceShipOne vehicle.

Missile defense work accounted for $2 million of the 2004 revenue, with the Air Force Research Laboratory contract contributing $1.7 million and SpaceShipOne $686,000 in revenue, said Richard Slansky, the companyโ€™s chief financial officer.

Despite the revenue jump, SpaceDev continues to report a loss due to non-cash interest expense related to financing activities, Slansky said. The expense charge was $3.3 million in 2004, up from $258,000 in 2003, he said.

SpaceDevโ€™s backlog stood at $47 million at the end of 2004, up from $2 million at the end of 2003, with the Missile Defense Agency leading the way, Benson said. Missile work should contribute another $8 million to revenue in 2005, he said.

Pentagon work will continue to drive SpaceDevโ€™s growth beyond 2005, with NASAโ€™s vision for space exploration also providing opportunities, Benson said.

โ€œNASA has become a tremendous potential customer and weโ€™re spending a lot of time working with a variety of NASA people at a bunch of different levels,โ€ Benson said. โ€œThis is a fun and exciting time ripe with opportunities. โ€œ
