Military & Spy Satellites: Who Has What in 2026

A military satellite is any spacecraft operated by, or built for, a defence or intelligence organisation. The category covers photographic and radar reconnaissance, eavesdropping on radio and radar signals, watching for missile launches, carrying secure communications, and providing the navigation and timing signals that modern forces depend on.

Our live catalogue lists 1,626 payloads in orbit that are run by a defence or intelligence agency, or that carry a designation used for military missions, spread across 7 countries and alliances. The figure on this page is rebuilt from the catalogue every day, and it counts retired hardware still circling the Earth as well as working spacecraft.

Military space began as a photographic problem. The first successful American reconnaissance satellite, CORONA, returned film from orbit in 1960 and flew for twelve years. The same orbital ground is now crowded with radar imagers, listening posts, infrared early warning telescopes and jam-resistant communications relays.

Telling military and civil spacecraft apart is the hard part today. Commercial fleets sell imagery that would once have been classified, broadband constellations carry military traffic, and the same navigation signal serves a delivery van and a guided weapon. This page counts objects by operator and designation, so the total is a guide rather than an order of battle.

Almost every defence payload in orbit fits one of seven roles. The first three gather intelligence, the next two support warning and command, and the last two underpin everything else.

The counter at the top of this page is rebuilt daily from our live catalogue. It counts payloads still in orbit that are either operated by a defence or intelligence agency or carry a designation used for military missions. Spent rocket stages and debris are excluded, so the number reflects spacecraft rather than launch hardware.

Three countries dominate. The United States has the largest and most capable fleet, China has expanded fastest over the past decade, and Russia continues to launch under the long-running Cosmos designation that covers most of its military payloads. Everyone else operates in the tens rather than the hundreds. For the full national picture, including civil and commercial fleets, see satellites by country, or go straight to the United States, China and Russia.

These are the objects that drive most of the reporting on military space: inspectors that shadow other satellites, a reusable spaceplane, and reconnaissance payloads whose orbits are never published. Orbit data below is live where the catalogue carries it. When one of these objects changes orbit, it surfaces in our satellite maneuver tracker; for current positions across the whole catalogue use the satellite directory, and for objects that have come down see the re-entered archive.

Rows marked as not publicly tracked have no published orbital elements. The objects are catalogued, but their positions are withheld, so amateur observers are usually the source of what is known about them.

United States. The largest fleet by a wide margin, split between reconnaissance satellites run by the National Reconnaissance Office and the navigation, communications, warning and space surveillance fleets operated by the Space Force. American defence payloads are catalogued under USA designations, and the imaging satellites among them are the ones most often withheld from public orbital data.

China. The People's Liberation Army has built out a full spectrum capability in under two decades. The Yaogan series covers optical and radar reconnaissance, the TJS satellites sit in geostationary orbit on missions widely assessed as warning and signals intelligence, and the Shijian series has demonstrated close approach and satellite towing. Browse the family on our Yaogan constellation page.

Russia. Most Russian military payloads launch under the Cosmos designation, which spans imaging, signals intelligence, early warning and navigation. Russia also flies the inspector satellites that have drawn the most attention in recent years, several of which appear in the table above.

Europe. France operates optical reconnaissance and signals intelligence satellites alongside its Syracuse communications fleet. Germany and Italy focus on radar imaging, and the United Kingdom runs the Skynet communications constellation for its armed forces. NATO itself owns no satellites: it buys capacity from member states.

Everyone else. India, Israel, Japan and South Korea all operate reconnaissance satellites, Israel launching westwards over the Mediterranean to keep debris off populated ground. Iran and North Korea have both placed military satellites in orbit, though their capability is limited.

In the United States the work is split. The National Reconnaissance Office builds and flies the imaging and signals intelligence satellites, the National Geospatial-Intelligence Agency turns their pictures into intelligence, the National Security Agency handles intercepted signals, and the Space Force operates navigation, communications, missile warning and space surveillance. The X-37B spaceplane is flown for the Space Force and its payloads are classified.

China's military space assets sit under the People's Liberation Army Aerospace Force, created in 2024 when the Strategic Support Force was reorganised. Russia's military satellites are operated by its Aerospace Forces, with Roscosmos handling civil programmes. In Europe, national defence ministries own their fleets directly, and in the United Kingdom the Skynet system is run for the Ministry of Defence under a long-term service contract.

Names matter for tracking: catalogues often list analyst codenames rather than official programme names, so one spacecraft can appear under several labels. Our satellites by operator page shows how fleets are grouped.

The clean division between military and civilian satellites no longer holds. Commercial imaging companies count armed forces among their biggest customers, broadband constellations built for consumers carry battlefield traffic, and weather, navigation and communications satellites serve both sides of the line at once.

That matters because targeting rules follow function, not ownership. If a commercial satellite supports military operations, some states argue it becomes a legitimate target, which is one reason anti-satellite weapons are back in the policy debate. It is also why counting military satellites is hard: the answer depends on whether you count hardware or mission.

Most military satellites other than reconnaissance payloads can be followed live: communications, navigation and radar imaging satellites appear in the public catalogue with current orbital elements, so you can watch them move and see when they change orbit.

You can also search the full catalogue in the satellite directory, check what launched and when in the launch log, see which objects have come back down in the re-entered archive, and read how orbit choice shapes a mission in types of orbits.
