Industry titans United Launch Alliance and SpaceX recently secured nearly $650 million in Air Force launch contracts, the Department of Defense said Wednesday.

Colorado-based ULA was awarded a $355 million contract for its launch services to deliver two Air Force Space Command spacecraft, labeled AFSPC-8 and AFSPC-12, to orbit. The missions are expected to launch from Cape Canaveral Air Force Station by June 2020 and March 2020, respectively.

"United Launch Alliance is honored to be selected to launch these critical national security satellites for our country," the company said in a statement Wednesday. "Reliably launching our customer's missions remains our top priority like we have for the more than 125 successful missions we have launched."

SpaceX, meanwhile, secured a $290 million contract to launch three next-generation Global Positioning System satellites for the Air Force, known as GPS III. The first is expected to launch from the Space Coast by March 2020, either from Cape Canaveral Air Force Station's Launch Complex 40 or Kennedy Space Center's pad 39A.

“SpaceX is pleased with the Air Force’s decision to select us for all five of the GPS III missions competed to date,” said Gwynne Shotwell, SpaceX president and chief operating officer. “We look forward to the successful completion of these important national security space missions.”

The announcement to give SpaceX three additional national security launches comes exactly a year after the Air Force awarded the California-based company $96.5 million to launch the third GPS III satellite from the Eastern Range in February 2019. SpaceX's lower price sealed its win over ULA, the Space and Missile Systems Center said last year.

Also announced Wednesday: SpaceX's selection to launch two satellites for DigitalGlobe, a satellite imagery company, on Falcon 9 rockets in 2021. Previously flown versions of the rockets, also known as "flight proven," will take the first batch of the multi-satellite WorldView Legion constellation to orbit.

"We appreciate DigitalGlobe selecting two flight-proven Falcon 9’s to reliably deliver their satellites to orbit," Shotwell said in a statement released by Maxar, DigitalGlobe's parent company.
