Space Force mulling nuclear protection for missile-tracking satellites

The Area Drive has launched a examine to contemplate what capabilities to host on future satellites that detect and observe superior, high-speed weapons.

Col. Rob Davis, who oversees house sensing acquisition efforts for the service, mentioned Thursday that as a part of that work, the Area Drive is weighing the best strategy for guaranteeing such spacecraft can survive a nuclear risk.

“We’re at present working with the Area Warfighting Evaluation Middle, the SWAC, to assist us determine what’s the following era of these capabilities,” Davis mentioned throughout a digital Nationwide Safety Area Affiliation occasion.

The service is within the early days of a long-term plan to strengthen its missile monitoring capabilities in opposition to threats from China and Russia, each of whom are creating hypersonic missiles that may journey and maneuver at Mach 5 speeds. The 2 international locations are additionally constructing, and in some circumstances testing, anti-satellite weapons that might impede protected operations in orbit.

The Area Drive at present depends on giant, costly satellites to carry out its missile warning mission. These spacecraft, a part of the Area-Primarily based Infrared System, are radiation-hardened, which suggests they’re outfitted with buildings and supplies that permit them to face up to a nuclear assault.

The service’s new technique strikes away from these extra beautiful capabilities and hinges as a substitute on constructing and fielding giant numbers of small satellites in decrease orbits. The Area Improvement Company, or SDA, and Area Techniques Command, or SSC, are main this effort, with SDA planning to launch a whole bunch of satellites to low Earth orbit, as much as 1,200 miles above sea degree. SSC is concentrated on medium Earth orbit capabilities, residing between low earth and geosynchronous orbit, about 22,000 miles up.

To this point, SDA has launched eight low earth orbit missile monitoring satellites. SSC is slated to launch its first medium Earth orbit, or MEO, spacecraft in 2026. Each organizations are delivering satellites in batches and plan to launch new variations each few years.

Over time, the Area Drive will section out the older programs and rely solely on this new structure. Nevertheless, within the close to time period, the service is working with Lockheed Martin and Northrop Grumman to construct 5 radiation-hardened Subsequent-Technology Overhead Persistent Infrared, or Subsequent-Gen OPIR, satellites to exchange the Area-Primarily based Infrared System.

Davis acknowledged that to this point, the Area Drive has centered extra on enhancing its potential to trace quicker, harder-to-spot targets and fewer on ensuring the brand new satellites are hardened in opposition to and will function via a nuclear assault. That’s partly because of the urgency of the monitoring functionality however can be owed to the fee that comes with making the spacecraft extra survivable.

One aim of the examine, Davis mentioned, is to seek out choices for nuclear safety that match inside the service’s long-term structure plans.

“We are able to’t neglect these different vital necessities,” he mentioned. “With an agile strategy to improvement, we’ll take a look at the result of that examine. And it could have an effect on future epochs or doubtlessly future tranches of each SDA’s work and our work to ensure we’re assembly the complete necessities for the nation.”
