Jamming

Jamming is a military tactic used to intentionally block or disrupt an enemy's electronic communications, radar, or navigation systems by sending out powerful interfering signals.

TECHNICAL DEFINITION

Jamming is an Electronic Warfare (EW) technique involving the deliberate emission of electromagnetic energy to degrade or deny the effective operation of targeted adversary systems, such as radar, radio communication, or Global Navigation Satellite Systems (GNSS), by overwhelming their receivers with interfering signals, thereby impacting situational awareness, command and control, or precision-guided munitions.

BACKGROUND

The military budget of the United States is the largest portion of the discretionary federal budget allocated to the Department of Defense (DoD), or more broadly, the portion of the budget that goes to any military-related expenditures. It pays the salaries, training, and health care of uniformed and civilian personnel, maintains arms, equipment and facilities, funds operations, and develops and buys new items. The budget funds the six branches of the US military: the Army, Navy, Marine Corps, Coast Guard, Air Force, and Space Force. Critics contend that recent U.S. defense budgets have disproportionately invested in long-term developmental programs instead of producing weapons systems needed in the near term.
