WASHINGTON – The U.S. Air Force expects to launch an experimental missile-warning satellite in 2018 or 2019, about two years later than the timeline service officials used last January.

In a Jan. 8 email to SpaceNews, Lt. Gen. Samuel Greaves, head of the Air Force's Space and Missile Systems Center, said the satellite will help ease new capabilities into the service's future missile warning satellites.

"Due to technical challenges not uncommon in a first-time development effort and budgetary uncertainty, the WFOV program has been delayed with a projected launch in calendar year 2018," he said.

In the Jan. 6 notice, the service said it was looking for commercial satellite companies to submit information on their capability to launch the missile warning satellite. The request suggests the Air Force is leaning toward a new contract to put the satellite on orbit, industry sources said.

"We expect multiple vendors to respond to our request for information, and are looking forward to reviewing their suggestions for innovative approaches to deploying the WFOV Testbed satellite," Greaves said. "This timeframe aligns with the current program schedule and includes sufficient margin to cover potential future delays."

Air Force officials have said experiments with a wide-field-of-view sensor are critical for two reasons. First, they help test and verify architectures for a follow-on program to the service's missile warning satellites, known as the Space Based Infrared System. Second, they help the Air Force develop the algorithms necessary to process the flood of data that would come from improved sensor focal-plane technology.
