The website discusses the potential for a small satellite to detect hidden nuclear weapons in space, the prohibition of such weapons by the Outer Space Treaty, and allegations against Russia regarding space-based nuclear weapons.
Infact verdict: Mostly True (65/100).
The claims regarding space-based nuclear weapons and the Outer Space Treaty are largely supported by credible evidence. The claim about shoebox-sized satellites detecting nuclear weapons is well-supported by scientific sources, indicating technological feasibility. The Outer Space Treaty ratification by 118 countries, including major powers like the U.S. and Russia, is confirmed by authoritative sources. Allegations about Russia's development of space-based nuclear weapons are reported by multiple sources, though they remain speculative without official confirmation. Overall, the evidence supports the factual basis of these claims, with varying degrees of certainty.

In recent years, the United States has claimed that Russia is developing a space-based nuclear weapon.
The claim is supported by evidence from sources like the Atlantic Council and SWP Berlin, which report on U.S. concerns about Russia developing nuclear-armed anti-satellite weapons. While these reports indicate significant international concern, there is no definitive proof of deployment, making the claim plausible but not fully verified.
