Military Space: Space Force, GPS, ASATs and Golden Dome — 2026-10-09
The US Space Force has officially retired its last Cold War-era missile warning satellites, marking the end of an era as new "Golden Dome" architecture takes shape. Simultaneously, the Space Development Agency launched a critical batch of transport satellites to bolster data relay capabilities, while South Korea successfully deployed military reconnaissance assets via its indigenous Nuri rocket.

Space Force Retires Last Soviet-Era Missile Warning Satellites
On October 6, 2026, the US Space Force officially decommissioned the final two satellites of the Defense Support Program (DSP), a constellation that had monitored for ballistic missile launches since the late 1970s. These spacecraft were moved to a "graveyard orbit," ending their decades-long mission of providing early warning for nuclear attacks. The retirement signifies the full transition to the Space Development Agency’s (SDA) proliferated architecture and the upcoming Golden Dome missile defense system, which relies on low-earth orbit constellations rather than high-altitude geosynchronous monitors.
SDA Launches 21 Transport Satellites for Proliferated Architecture
On October 5, 2026, the Space Development Agency launched 21 Northrop Grumman-built Tranche 1 data transport satellites from Vandenberg Space Force Base. This mission adds a third vendor to the Proliferated Warfighter Space Architecture (PWSA), which now includes 63 satellites from prior launches. The goal is to create resilient "enclaves" of satellites that can relay critical sensor data to warfighters even if individual nodes are attacked or jammed, a core tenet of the new space defense doctrine.
South Korea’s Nuri Rocket Deploys Military Reconnaissance Fleet
On October 8, 2026, South Korea’s indigenous Nuri rocket successfully placed 15 satellites into orbit, including five KAIST NEONSATs and several military reconnaissance assets. This launch demonstrates Seoul’s growing capability to launch its own spy satellites, reducing reliance on foreign launch providers for sensitive national security payloads. The mission underscores the regional arms race in space, with neighboring powers also accelerating their independent launch capabilities.
Global Counterspace Threats Highlighted in New Report
A newly released report by the Secure World Foundation assesses counterspace capabilities in 13 countries, noting a shift toward operational deployment rather than just testing. The report details how nations are developing co-orbital, direct-ascent, and electronic warfare capabilities, directly influencing the Space Force’s push for hardened GPS III satellites and the Golden Dome interceptor program.
Local view
Russian Media Focuses on "Orbital Confrontation" Russian state-affiliated media continues to frame the US Space Force's activities as aggressive militarization. EADaily reported on October 2 that the "militarization of space cannot be stopped," citing US admissions of orbital weapons as proof that the battlefield is already active. Meanwhile, TopCor highlighted General Stephen Whiting’s statements that Russia has moved from testing to deploying operational anti-satellite systems, framing the situation as a mutual escalation where both sides are preparing for combat in orbit.
Chinese Commentary Warns of "Sputnik Moment" Chinese-language outlets such as NTD and Bannedbook have circulated commentary suggesting that China faces a "Sputnik moment" due to US advancements in space control weapons. Articles emphasize that US recognition of orbital weapons poses a direct threat to Chinese satellite security, urging Beijing to accelerate its own counter-space capabilities.
Context & numbers
- GPS Costs: A single GPS III satellite costs approximately $529 million, highlighting the high stakes of protecting navigation assets from jamming and kinetic attack.
- Golden Dome Budget: The FY27 budget request includes significant boosts for Golden Dome programs, with $3.2 billion previously awarded for space-based interceptor development contracts.
- Starlink Maneuvers: To illustrate the crowded orbital environment, Starlink satellites performed 207,152 collision avoidance maneuvers in the first half of 2026, averaging about 1,140 per day.
On the radar
- WISeSat.Space Launch: WISeSat.Space and Fossa Systems have confirmed a satellite launch for October 2026, advancing the QSOC constellation which focuses on secure digital identity and blockchain-based satellite tech.
- NRO Contract Watch: Following the successful Falcon Heavy launch of NROL-97 on October 1, attention turns to the next NSSL Phase 3 Lane 2 awards, which will determine the future heavy-lift partners for National Reconnaissance Office missions.
