Orbital mesh has not yet entered construction
The Space Development Agency’s plan to build an orbital network capable of transferring data directly from satellite to satellite is facing major delays. The project, considered central to the future U.S. military space architecture, is now at least a year behind its original schedule.
About six months ago, SDA Director G.P. Sandhoo said the program was roughly three months behind schedule and that construction could begin within six months. That self-imposed deadline expires in approximately 10 days, but work has not yet started.
Sandhoo acknowledged that the agency will miss the target and now expects the effort to begin no earlier than three months from now. That would bring the total projected delay to at least one year.
Optical components emerge as the main bottleneck
One of the primary challenges is obtaining enough optical communications terminals, which are essential for transferring data between satellites through laser links.
The components, often referred to as optical heads, must meet two demanding requirements: they must be precise enough to transmit and receive clear signals, while also being rugged enough to survive launch and operate in space.
The problem combines the engineering challenges of space systems with broader supply-chain difficulties. According to the agency’s leadership, the supplier selected for the first group of satellites has been unable to deliver the equipment at the required pace.
Initial contracts concentrated production with one supplier
To control costs, the agency used firm-fixed-price contracts for the first generation of satellites in the Proliferated Warfighter Space Architecture, or PWSA.
However, the procurement process resulted in all of the first tranche’s contracts being awarded to the same optical-terminal supplier. That company is now experiencing production-capacity problems and cannot provide the required number of systems.
The agency’s leadership says it has not seen the expected production improvements for the first tranche of satellites. To reduce risk in the next phase, officials plan to establish a second supply path that would allow terminals from another manufacturer to be incorporated later in the design process.
Network designed to support missile warning and tracking
The orbital mesh is a high priority because it is intended to accelerate data transfers across the PWSA. The architecture is expected to include hundreds of satellites supporting missile warning, tracking and fire-control missions.
Rather than sending data first to ground stations and then relaying it to other satellites or military units, the spacecraft would be able to communicate directly with one another. Laser links, instead of radio waves, would enable faster and more efficient transmission of large volumes of information.
The delay therefore affects one of the most important elements of the future U.S. military space infrastructure.
Artificial intelligence will follow basic network deployment
The long-term plans are even more ambitious. PWSA satellites could eventually receive edge-computing capabilities and artificial-intelligence tools capable of processing large volumes of data in orbit.
Onboard processing would reduce the amount of information sent back to Earth, conserve space-to-ground bandwidth and speed the delivery of priority data to military users.
That phase, however, will come only after the satellites are launched and the basic communications network is operational. For now, the immediate priority is to build the orbital infrastructure and resolve the production and supply-chain problems delaying the program.
