WASHINGTON — The U.S. Space Force’s Space Development Agency said it received initial images from its first missile-warning satellites launched April 2 to low Earth orbit.
“First tracking sats, built by SpaceX, achieved break of day: infrared images using wide-field-of-view sensors,” the agency said June 14 in a twitter post.
The 2 tracking satellites were a part of SDA’s first Tranche 0 launch, which also included eight data-transport satellites made by York Space Systems.
SDA plans to construct a proliferated low Earth orbit network of data-transport satellites and a constellation of infrared sensor satellites to offer a defense shield against Russian and Chinese ballistic and hypersonic missiles.
The eight York satellites are “performing as expected,” SDA said, although certainly one of them had an “assembly issue.” These transport satellites will remain of their initial orbit to conduct tests of their Link 16 data-communications terminals. “Will raise orbit once initial tactical comms testing is finished,” said the agency.
Second launch delayed
SDA was expecting to launch the second batch of Tranche 0 satellites in late June but that mission is more likely to be delayed by no less than a month, the agency said.
There are 13 satellites in SDA’s second launch.
“We’re targeting the second launch near the top of July,” an SDA official said in an announcement June 16.
“While we’ve experienced some delays, SDA is working collaboratively with partners to assemble critical elements required for the rest of Tranche 0 to perform its intended tactical data demonstrations,” the official said.
The 13 satellites include 10 Lockheed Martin Transport satellites, two SpaceX Tracking satellites, and one York Transport satellite.
4 L3Harris Tracking satellites which can be also a part of the Tranche 0 constellation is not going to launch with the opposite Tranche 0 satellites and are being moved to a future launch with other Missile Defense Agency sensor satellites.
