The US Space Development Agency (SDA) has awarded SpaceX a $9.92 million contract aimed at exploring the integration of the company's laser inter-satellite communication technology into the agency's own spacecraft. According to the agreement, the work will help assess the technical compatibility of two satellite networks, which are being developed under separate programs and currently operate independently. The contract specifically covers the research phase and equipment preparation, not a confirmed deployment of a single unified network.
Plaser technology: the subject of research
The central object of the study is SpaceX's proprietary Plug and Play Laser technology, known by the abbreviation Plaser. It is designed to transmit data between satellites via laser links, which allows for the creation of a high-speed inter-satellite backbone without relying on ground-based relays. Under the contract, the contractor must investigate the risks of integrating this system into SDA spacecraft, supply standard equipment, and provide technical support when connecting to the missile warning and tracking system.
PWSA and SpaceX's backbone network
This work is part of a broader SDA effort to ensure interoperability between its Proliferated Warfighter Space Architecture (PWSA) and SpaceX's separate backbone network. The PWSA is a distributed satellite system being developed by the agency, while SpaceX's commercial network is designed to transmit large volumes of data from space sensors, including targeting information. Thus, the focus is on bridging two architectures, each of which is evolving within its own program.
The expected result of the research
The outcome of the contract should be a clear understanding of whether it is possible to link the two satellite infrastructures and ensure sustainable data exchange between them. The resulting compatibility data and supplied hardware will allow the SDA to make an informed decision about further integration of laser channels into its warning and tracking system. At this stage, the project focuses on technical preparation and risk assessment, rather than the deployment of a single network.
The context of Pentagon's reliance on SpaceX
The contract fits into a broader context of the increasing dependence of American military programs on SpaceX infrastructure. Previously, there were reports regarding problems with booking launches on the Falcon 9 rocket after 2028, as well as restrictions the company imposed on Starlink services which, according to various parties, affected military operations. Against this backdrop, studying alternative and complementary communication channels, including laser links, becomes a way for the SDA to diversify and strengthen its own satellite architecture.
