Space Development Agency awards SpaceX $9.9 million contract to study Plaser laser terminals

On Nov. 9, 2026, the Space Development Agency awarded SpaceX a $9.9 million contract to study how its Plaser laser terminals integrate with the agency’s missile warning and tracking satellites at company sites in Hawthorne, California, and Redmond, Washington.

The study will examine hardware, software and connectivity challenges in transmitting data from the agency’s Tracking Layer satellites in low Earth orbit using SpaceX’s Plug and Play, or Plaser, optical terminals, an SDA spokesperson said. The spokesman described the effort as an initial step, leaving potential hardware and software pathways under consideration. The Tracking Layer is part of the agency’s missile warning, tracking and targeting architecture in low Earth orbit.

The U.S. Department of War announced the award on Nov. 10, 2026, after the Space Development Agency made it on Nov. 9, 2026. Options could raise the value to nearly $12.7 million. The full $9.9 million comes from fiscal 2026 research, development, test and evaluation funds and was obligated at the time of award, with the study set to finish Oct. 7, 2027. SDA bought the study through its Systems, Technologies, and Emerging Capabilities broad agency announcement, an open solicitation accepting proposals throughout the year, so the number of competing bids is not known.

The announcement does not say which tranche or satellite design the Plaser study supports, what the representative hardware will be, or whether the agency plans a follow-on purchase. The study ends in October 2027, about 18 months before the first Tranche 3 tracking satellites are due to launch, and answers would come after the study ends. SDA has also not said whether Plaser could fly aboard Tracking Layer satellites or connect them to another network.

SpaceX developed Plaser, short for Plug and Plaser, to let satellites exchange data using laser light and began offering it to other satellite operators in March 2024. SpaceX President Gwynne Shotwell told Reuters in March 2024 that selling Plaser commercially was new for a company that generally builds everything itself. “We generally don’t sell components, so this is a little bit of a new thing for us,” said SpaceX President Gwynne Shotwell.

A smaller Starlink mini laser terminal that Muon Space agreed in October 2025 to integrate into its Halo platform is rated at 25 gigabits per second up to 4,000 km, with higher speeds at shorter range, equal to 2,485 miles. SpaceX has disclosed few specifications for Plaser itself, so the smaller terminal serves as a point of reference. Optical links offer greater data capacity than radio links, yet keeping a link alive demands that terminals aim precisely at one another while the satellites move.

SDA tests vendors’ optical terminals at the U.S. Naval Research Laboratory under its own standard. As of March 2024, SpaceX had not submitted its commercial terminals, while Tesat-Spacecom, Mynaric, Skyloom and CACI/SA Photonics had passed. The contract announcement does not say whether the study will test Plaser against the SDA standard.

The Space Development Agency’s Proliferated Warfighter Space Architecture (PWSA) relies on hundreds of small satellites in low Earth orbit passing data to one another by light rather than radio, making optical laser links central to its missile-tracking plan. Optical links are harder to detect or jam than radio links, and Tracking Layer satellites use optical terminals to send data through the Transport Layer mesh network to ground stations and weapon systems. Tracking Layer satellites carry infrared sensors for ballistic and hypersonic missiles.

Plaser terminals provide the satellite-to-satellite laser links at the heart of the Space Force’s Space Data Network Backbone, built by SpaceX for high-speed, low-latency military communications with a near-term focus on Golden Dome missile defense. The Space Data Network is a low Earth orbit constellation meant to carry missile-warning and tracking data for Golden Dome. In May 2026, the U.S. Space Force awarded SpaceX a $2.29 billion fixed-price agreement to build the Space Data Network backbone for Golden Dome missile defense, requiring a fully operational prototype by the end of 2027. The Space Force said the network would carry missile-warning and tracking data for Golden Dome and operate alongside SDA’s Transport Layer.

Tranche 1 is planned to include 126 Transport Layer satellites, 28 Tracking Layer satellites and four missile defense demonstration spacecraft; the full Transport Layer will have 300 to 500 satellites at 750 km to 1,200 km altitude. T1TL-A is the fourth SDA production satellite mission and one of 23 NSSL Phase 2 missions awarded to SpaceX in August 2020, managed by the U.S. Space Force’s Space Systems Command. Earlier production missions were T1TL-B on Sept. 10, 2025, T1TL-C on Oct. 15, 2025, and T1TL-E on July 16, 2026.

Tranche 1 is expected to provide operational capabilities to the Department of Defense beginning in 2027, and 95 percent of the globe will see at least two T1TL satellites at any time. SpaceX launches much of the SDA constellation under National Security Space Launch task orders, including a $5.9 billion Pentagon launch deal awarded in 2025, and has flown several SDA satellite batches on Falcon 9 rockets. SDA launches are managed by SSC’s System Delta 80 (SYD 80) and the Space Force Portfolio Acquisition Executive for Assured Access to Space.

SDA issued an RFI on Oct. 20, 2026, seeking next-generation missile-tracking technologies for its Tracking Layer, with industry responses due Dec. 4, 2026, to inform the Tranche 4 solicitation. SDA issued the RFI to close tracking gaps for maneuvering hypersonic missiles across their full flight envelopes on the PWSA Tracking Layer. The document lays out a two-track approach that balances full-rate production contracts for Tranche 4 Tracking Layer satellites with separate partnership deals for rapid prototyping and brief on-orbit flight demonstrations. Tranche 4 follows the agency’s two-year spiral development cycle fielding new LEO spacecraft generations to pace aerial threats.

Central to the Tranche 4 RFI is the integration of enhanced Missile Warning, Tracking, and Defense payloads capable of maintaining continuous track custody over advanced maneuvering targets. Tranche 4 seeks infrared and electro-optical payloads for hypersonic glide vehicles and cruise missiles across full flight trajectories, and vehicles will use optical links to route fire-control data into the PWSA Transport Layer mesh network. The links would carry fire-control data for rapid dissemination to tactical warfighters. Industry responses to the Tracking Layer Tranche 4 RFI are due Dec. 4, 2026, and feedback will shape the Tranche 4 request for proposals and define parameters for orbital prototype flight demonstrations toward late 2020s.
