The Space Development Agency was established in 2019 to help speed up the deployment of US military space systems by sidestepping the Pentagon\u2019s traditional sluggish bureaucracy.<\/p>\n

Seven years later, SDA is finally launching its first batches of operational satellites, just as the Pentagon plans to shutter the semi-autonomous agency and fold it back into the Space Force\u2019s procurement pipeline, newly reorganized under several program acquisition executives in a bid to streamline weapons buying.<\/p>\n

SDA\u2019s fate is not a surprise, and lawmakers in both houses of Congress have backed the agency\u2019s closure in drafts of this year\u2019s National Defense Authorization Act.<\/p>\n

The Space Development Agency\u2019s primary mission has been to develop a constellation of several hundred missile warning and data relay satellites in low-Earth orbit designed to detect, track, and target ballistic and hypersonic missiles. The military calls the constellation the Proliferated Warfighter Space Architecture (PWSA). The Pentagon currently has a small fleet of legacy missile warning satellites in much higher geosynchronous orbits. These satellites are expensive and vulnerable to attack, and their distance from Earth makes them less sensitive to smaller, dimmer missiles.<\/p>\n

The idea was to rapidly procure, develop, and field new generations, or tranches, of tracking and data \u201ctransport\u201d satellites every two years. SDA\u2019s strategy was to cast a wide net across the US space industry, using satellites and sensors developed by many companies. Launches of SDA\u2019s new satellites were supposed to occur at a cadence of about once per month.<\/p>\n

Rough waters<\/h2>\n

Much of SDA\u2019s mission will continue under a different banner within the US Space Force. The missile-warning and data-relay satellites will eventually be part of the Pentagon\u2019s planned Golden Dome missile shield, one of the Trump administration\u2019s top priorities for the Space Force.<\/p>\n

,<\/p>\n

The capabilities foreseen for SDA\u2019s satellite constellation predate President Trump\u2019s announcement of Golden Dome last year, and are far less controversial than the White House\u2019s push to include space-based weapons as part of the missile shield.<\/p>\n

SDA\u2019s history has been marred by schedule delays, production and supply chain bottlenecks, and technical issues with the organization\u2019s first batches of operational data relay satellites after their launch last year. The purpose of the data relay, or \u201ctransport,\u201d satellites is to receive tracking data from SDA\u2019s missile-warning satellites via inter-satellite laser communication links and relay the information to the ground for action.<\/p>\n

SDA started launching prototype tracking and data transport satellites in 2023 and launched its first two batches of transport satellites last year. The third group of data transport satellites launched Thursday on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base, California, bringing the total number of transport satellites launched in Tranche 1 to 63.<\/p>\n

\u201cThis launch continues to expand warfighting capability to deliver persistent tactical satellite communication for the warning and tracking of advanced missile threats,\u201d said Gurpartap \u201cGP\u201d Sandhoo, director of the Space Development Agency, in a statement. Sandhoo also serves as the Space Force\u2019s portfolio acquisition executive for missile warning and tracking, which would keep him in charge of much of the SDA\u2019s mission after the agency\u2019s dissolution.<\/p>\n

\u201cThe deployment of Tranche 1\u2019s proliferated capability will soon deliver continuous overwatch\u2014neutralizing any first-mover advantage by delivering data to warfighters around the world, nearly instantaneously,\u201d Sandhoo said.<\/p>\n

Thursday\u2019s launch marked the resumption of SDA satellite deployments after standing down for nine months due to issues with the spacecraft on the first two Tranche 1 launches last September and October. Those launches were successful, but ground teams ran into problems activating and commissioning satellites made by York Space Systems and Lockheed Martin.<\/p>\n

,<\/p>\n

Sandhoo identified several issues with the first Tranche 1 satellites during a roundtable with reporters before this week\u2019s launch. Ground controllers lacked sufficient ground station coverage to communicate with the satellites after last year\u2019s launches. Some of the satellites encountered thermal control and propulsion system problems as they climbed from their insertion orbit to an operational altitude of more than 600 miles (1,000 kilometers), significantly higher than SpaceX\u2019s Starlink Internet network, Sandhoo said.<\/p>\n

\u201cWe are in a pretty harsh radiation environment at 1,000 kilometers, so not all of our orbit raising has gone according to plan,\u201d he said. \u201cIt has been sporadic. We\u2019re working through it.\u201d Sandhoo is optimistic that ground teams will eventually declare most of the satellites ready for operations, but it\u2019s taking longer than expected.<\/p>\n

Getting it right<\/h2>\n

SDA and its contractors \u201ctook a pause\u201d after last year\u2019s launches to \u201cmake sure we fixed at least the known issues,\u201d Sandhoo said. \u201cWe expect this launch to be a lot smoother than the last one.\u201d<\/p>\n

Thursday\u2019s launch was the second SDA launch of York\u2019s data transport satellites, and the third for Tranche 1 overall. Seven more launches will complete Tranche with 63 additional data transport satellites and 28 missile tracking satellites manufactured by Lockheed Martin, Northrop Grumman, and L3Harris. None of the Tranche 1 tracking satellites have launched yet.<\/p>\n

Sandhoo said the schedule for the next series of SDA satellites is \u201cstill constrained\u201d by the availability of optical communication terminals, the laser transmitters and receivers needed to connect the transport and tracking satellites into one integrated mesh network.<\/p>\n

While SDA officials declined to say when the next few launches might occur, the agency said the Tranche 1 satellites will \u201cprovide initial warfighting capability beginning in 2027. Sandhoo said the agency is no longer focused on achieving a monthly launch cadence. It\u2019s more important, he said, to make sure SDA\u2019s satellites launch when they are ready. \u201cThe goal is to get operational as quickly as possible once you get in orbit,\u201d he said.<\/p>\n

,<\/p>\n

If all the Tranche 1 satellites had launched as originally scheduled, the constellation\u2019s enhanced missile warning capability might have been available to military commanders today. That might have proven useful for US and allied forces to counter Iranian ballistic missiles launched during the current war in the Middle East.<\/p>\n

\u201cThat\u2019s what I think the nation needs right now, to face the threat that we are in,\u201d Sandhoo said. \u201cIf you see what\u2019s going on, I wish we were on orbit and supporting this mission right now because, literally, missiles are being launched at the joint force every single day in [Operation] Epic Fury.<\/p>\n

\u201cWe are where we are,\u201d Sandhoo said. \u201cBut we are doing everything we can to solve these technical challenges to get these systems on orbit, so we can deliver these capabilities.\u201d<\/p>\n

In all, SDA\u2019s Tranche 1 constellation will number 154 operational satellites when complete. Tranche 2, set to begin launching next year, will include more than 250 transport and tracking satellites supplied by six manufacturers. SDA has ordered 108 satellites in the Tranche 3 tracking layer due to start launching in 2028.<\/p>\n

The transport layer will end after Tranche 3. It will be superseded by the Space Force\u2019s Space Network. The Space Force announced in May that it selected SpaceX to build the SDN \u201cbackbone\u201d using technology originally developed for SpaceX\u2019s Starlink broadband constellation. SDA\u2019s transport satellites will fold into the Space Data Network to work alongside SpaceX\u2019s satellites, Sandhoo said.<\/p>\n","protected":false},"excerpt":{"rendered":"
