The Transformational Satellite Communications System (TSAT) program was a United States Department of Defense (DOD) program sponsored by the U.S. Air Force for a secure, high-capacity global communications network serving the Department of Defense , NASA and the United States Intelligence Community (IC). It was intended as an enabler of net-centric warfare that would facilitate defense and intelligence professionals making rapid decisions based on integrated, comprehensive information. In 2003, the estimated project costs for the period up to 2015 were estimated to US$ 12 billion (inflation adjusted US$ 19.9 billion in 2023). In October 2008, the DoD announced that it was postponing making a decision on choosing a contractor to build the system until 2010. In April 2009 Secretary of Defence Robert M. Gates asked that the project be canceled in its entirety.

The National Military Establishment was renamed the "Department of Defense" on August 10, 1949, and absorbed the three cabinet-level military departments, in an amendment to the original 1947 law.

3196-521: The general public. In the 20th century, when the federal government began to provide funding and supervision for matters which were historically seen as the domain of state governments (i.e., education , health and welfare services , housing , and transportation ), Congress frequently authorized only funding for grants which were voluntary, in the sense that state or local government agencies could choose to apply for such grants (and accept conditions attached by Congress) or they could decline to apply. In

3264-404: The jurisdiction of other congressional committees.

3672-579: The next five years without layoffs or reduction in military personnel. In 2016, The Washington Post uncovered that rather than taking the advice of the auditing firm, senior defense officials suppressed and hid the report from the public to avoid political scrutiny. In June 2016, the Office of the Inspector General released a report stating that the Army made $ 6.5 trillion in wrongful adjustments to its accounting entries in 2015. The Department of Defense failed its fifth audit in 2022, and could not account for more than 60% of its $ 3.5 trillion in assets. In

Deliberations in Congress went on for months focusing heavily on the role of the military in society and the threat of granting too much military power to the executive.

3876-553: The president must implement a Saxbe fix . As is evident from the chart below, several executive departments (Education, Health and Human Services, Housing and Urban Development, and Transportation) have disproportionately small employee headcounts in contrast to the size of their budgets. This is because many of their employees merely supervise contracts with private independent contractors or grants (especially categorical grants ) to state or local government agencies who are primarily responsible for providing services directly to

3944-442: The president on military matters. The composition of the Joint Chiefs of Staff is defined by statute and consists of the chairman of the Joint Chiefs of Staff (CJCS), vice chairman of the Joint Chiefs of Staff (VCJCS), senior enlisted advisor to the chairman (SEAC), the Military Service chiefs from the Army , Marine Corps , Navy , Air Force , and Space Force , in addition to the chief of National Guard Bureau , all appointed by
