What is the United States Space Force (USSF)?

United States Space Force

The United States Space Force (USSF) is the space service branch of the United States Department of Defense. It is one of the six armed forces of the United States and one of the eight uniformed services of the United States. It is also one of only two independent space forces in the world, along with that of China.

The Space Force is organized as part of the Department of the Air Force alongside the U.S. Air Force, a coequal service. The Department of the Air Force is headed by the civilian secretary of the Air Force, while the U.S. Space Force is led by the chief of space operations. The U.S. Space Force's status as part of the Department of the Air Force is intended to be an interim measure towards a fully independent Department of the Space Force, led by a civilian secretary of the Space Force

The Space Force has the following structure of military units:

a section consists of two or more guardians; this is also referred to as an "element" in basic training
a flight comprises Individual guardians or sections
two or more flights form a squadron (commanded by major or lieutenant colonel) — the lowest level of command, usually identified by number and function
two or more squadrons form a delta (commanded by colonel); there are three types of deltas:
mission delta is responsible for an entire mission set for the service
space base delta is responsible for base support on Space Force bases
space launch delta is responsible for both base support and the launch mission for its Space Force base
field commands (commanded by major general or lieutenant general) are responsible for organizing, training and equipping thousands of guardians around the world; a field command is organized by mission, such as Space Training and Readiness Command, and reports directly to headquarters at the Pentagon
service component field commands (commanded by colonel or brigadier general) integrate Space Force capabilities with other service branches and combatant commands, serving as the bridge between the Space Force and the broader joint military structure; they are organized under the combatant command they support
