Illustration: Pentagon signals interest in a fleet of military satellites around the Moon
The US military has published a Request for Information signaling interest in deploying a “proliferated cislunar constellation” of satellites in the vicinity of the Moon.

The request concerns an unspecified number of satellites performing an undisclosed mission in the vicinity of the Moon. It follows statements in recent months from Space Force acquisitions chief for advanced programs Maj. Gen. Stephen Purdy that the military was getting serious about extending its reach to the Moon.

The Space Force’s most distant satellites today are in geostationary orbit, some 22,000 miles (36,000 kilometers) over the equator, where they collect routine surveillance and missile warning data. Purdy most recently spoke of a shift in Pentagon leadership’s thinking about the Moon after President Donald Trump signed an executive order last December setting out the administration’s space policy. One section of the order deals with the US government’s ability to detect, characterize, and counter threats to US space interests from low-Earth orbit to cislunar space, the region of space around the Moon.

Analysis

Why This Matters

  • The move signals that the US military sees the Moon and its surrounding space as a potential domain for strategic competition, comparable to the way low-Earth orbit has become militarised.
  • A cislunar constellation would require new technologies in propulsion, communications, and radiation hardening, potentially driving investment in the space industry.
  • The lack of disclosed mission details raises questions about the purpose, whether the satellites would serve navigation and communications for future lunar operations, surveillance, or counterspace activities.

Background

The US Space Force currently operates its most distant assets in geostationary orbit, about 22,000 miles above Earth. These satellites perform early warning and surveillance. Cislunar space refers to the region from Earth orbit out to and around the Moon. President Donald Trump signed an executive order in December 2025 that set out US space policy, including language about detecting and countering threats to US space interests from low-Earth orbit to cislunar space. That order appears to have prompted a shift in Pentagon leadership's thinking.

Key Perspectives

Maj. Gen. Stephen Purdy (Space Force acquisitions chief for advanced programs): Has said in recent months that the military is getting serious about extending its reach to the Moon; most recently spoke of a shift in Pentagon leadership's thinking about the Moon after the president's executive order.

The Trump administration's executive order: Sets out US space policy; one section deals with the government's ability to detect, characterize, and counter threats to US space interests from low-Earth orbit to cislunar space.

What to Watch

  • Whether the Request for Information leads to a formal programme office or a contract solicitation within the next year.
  • Any public statements from other spacefaring nations (China, Russia) about cislunar military activity.
  • Congressional budget allocations for cislunar programmes in the next defence appropriations bill.
