The Space Development Agency launched its initial batch of operational satellites on Wednesday, kicking off a 10-month campaign to deliver more than 150 satellites to low Earth orbit.<\/p>\n
The 21 satellites, all built by York Space Systems<\/a>, flew on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California. The spacecraft are part of SDA\u2019s Transport Layer, designed to provide fast, secure communication capability to military operators. <\/p>\n The launch represents a new phase for SDA, which since 2019 has been crafting plans for a large constellation of government-owned missile tracking and data transport satellites in low Earth orbit. Its first spacecraft, Tranche 0, launched in 2023 and 2024 and have been used to demonstrate capabilities like laser communication between satellites, with the ground and recently between a commercial partner\u2019s satellite<\/a> and an SDA terminal installed on an aircraft in flight. <\/p>\n Once on orbit, the Tranche 1 satellites launched today will build on that work. Following initial payload health and safety checks, the spacecraft could start providing operational capability to combatant commands and other users within four to six months, according to acting SDA Director Gurpartap Sandhoo.<\/p>\n \u201cThis is the first time we\u2019ll be able to start working with our COCOMs, our joint force to start integrating space into their operations and getting the warfighters used to using space from this construct,\u201d Sandhoo told reporters prior to the launch. \u201cThis is the first time we\u2019ll have the space layer fully integrated into our warfare operations.\u201d<\/p>\n SDA\u2019s first user group, whom Sandhoo called \u201cearly adopters,\u201d includes military operators in the Indo-Pacific. This initial work is key, he added, to familiarize the services and combatant commands with the capability SDA can provide.<\/p>\n \u201cDoing the warfighter immersion is going to be critical because they have to get trained on this and we have to provide this capability,\u201d Sandhoo said. \u201cThat\u2019s what Tranche 1 will start doing.\u201d<\/p>\n Tranche 1 will include 154 satellites \u2014 126 for the Transport Layer and 28 for the Tracking Layer. The first 21 spacecraft will bring a limited coverage and capacity, but that will increase over time as more reach orbit. <\/p>\n Starting with today\u2019s launch, SDA plans to fly a new batch of Tranche 1 satellites each month for 10 months, with six of those missions carrying transport spacecraft and four flying missile warning and tracking satellites. The first few launches will be dedicated transport missions, but Sandhoo said tracking satellites will start to fly early next year. <\/p>\n The next mission is slated for mid-October and will feature satellites built by Lockheed Martin.<\/p>\n By the end of Tranche 1, Sandhoo said, SDA hopes to be providing regional capacity. Tranche 2, scheduled to start launching in late 2026, will further expand the constellation\u2019s reach. <\/p>\n The agency is making headway on future missile tracking capabilities beyond Tranche 2 \u2014 which could provide essential support for the Pentagon\u2019s Golden Dome missile shield<\/a> \u2014 but the longer-term future of the Transport Layer is uncertain. The effort is fully funded through Tranche Two, but the Space Force has paused work on Tranche 3<\/a> amid an ongoing study considering whether the constellation is the best solution to meet the U.S. military\u2019s data transport needs.<\/p>\n Sandhoo said the stalled funding will delay SDA\u2019s plans to expand from regional to global transport coverage. <\/p>\n Courtney Albon is C4ISRNET\u2019s space and emerging technology reporter.
