Cislunar
Cislunar refers to the region of space located between the Earth and the Moon, including the Moon's orbit and gravitational influence. It represents a vast area beyond traditional Earth orbits.
TECHNICAL DEFINITION
Cislunar space defines the geocentric volume extending from Earth's geostationary orbit to the lunar orbit, encompassing key orbital regimes and Lagrangian points, making it a strategically vital domain for military intelligence, surveillance, reconnaissance, and potential future off-world operations within the space and counter-space context.
BACKGROUND
The United States Armed Forces are the military forces of the United States. United States federal law establishes six armed forces: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard, each assigned specific roles and operational domains. With the exception of the Coast Guard, which operates under the Department of Homeland Security (DHS) in peacetime, the services are organized under the Department of Defense (DoD).
