The U.S. Department of Defense typically replaces GPS satellites every 10 to 15 years, with ongoing efforts to modernize the constellation. The GPS III program aims to enhance capabilities and ensure the system remains reliable. The Department of Defense continuously monitors the satellites' health and performance to determine the timing of replacements. New satellites are launched as needed to maintain and improve the overall GPS service.

The emblem reflects the department's role in national defense and military readiness.
The most influential agency in the Department of Defense (DoD) is often considered to be the Defense Intelligence Agency (DIA). The DIA plays a crucial role in providing intelligence and analysis to support military operations and national security decision-making. Additionally, the Office of the Secretary of Defense (OSD) holds significant sway, as it oversees policy formulation and budgetary decisions across the military branches. Together, these entities shape U.S. defense strategy and operations.
The most common form used to move funds from a Department of Defense (DoD) agency or component is the Standard Form 1080 (SF 1080), known as the "Voucher for Transfers Between Appropriations."

Additionally, the Department of Defense Financial Management Regulation outlines the procedures for these fund transfers.
The Missile Defense Agency (MDA) collaborates with various organizations, including the U.S. Department of Defense, other federal agencies, and international partners. It often works alongside military branches like the Army, Navy, and Air Force to develop and implement missile defense systems. Additionally, the MDA partners with private defense contractors and research institutions to advance technology and capabilities in missile defense.
The process by which the Department of Defense identifies, assesses, and prioritizes military capabilities is known as the requirements generation process. This systematic approach involves collaboration among various stakeholders, including military services, defense agencies, and policymakers, to ensure that the necessary resources and technologies align with mission objectives. By prioritizing these requirements, the Department can effectively allocate funding and develop strategies to meet current and future operational needs.

Many positions may also prefer or require a master's degree, especially for more advanced roles. Relevant experience, internships, and knowledge of defense policies or military operations can enhance job prospects. Additionally, security clearance is often necessary for these positions.
Once in space, most satellites obtain their power from the Sun using solar panels. Satellites travelling deep into space often carry additional nuclear power supplies.
