// ORBITAL LOGISTICS AND PROPULSION TERM
Delta-V
A measure of the change in velocity required to perform an orbital maneuver, like changing altitude or direction. It's essentially the 'fuel budget' for space missions.
TECHNICAL DEFINITION
Delta-V (Δv) quantifies the total change in velocity a spacecraft needs to execute orbital maneuvers, such as orbit insertion, rendezvous, or plane changes, directly correlating with propellant consumption.
BACKGROUND
The United States Space Force (USSF) is the space service branch of the United States Armed Forces, and was established on 20 December 2019. Part of the United States Department of Defense, it is one of the six armed forces and one of the eight uniformed services of the United States. It is the second independent space force to have been formed, after the Russian Space Forces; together with that of China, it is one of only two still extant.

USAGE NOTE
Engineers use delta-V calculations to design spacecraft propulsion systems and plan mission trajectories.
