US Military Prepares for Combat Operations From Seabed to Lunar Space

General Dan Caine, chairman of the Joint Chiefs of Staff, has called on the US military to begin adapting immediately for potential conflict across an expanding range of domains. His remarks highlight growing concerns about competition in space, stretching from deep-sea environments to cislunar space — the region between Earth and the Moon. Caine emphasized that the current space environment is becoming increasingly contested, requiring proactive military readiness. The statement signals a significant shift in how the US armed forces are thinking about the future battlefield beyond Earth's atmosphere.
