Layered Defense

Layered defense is a military strategy that uses multiple, overlapping defensive systems positioned at different ranges or altitudes to protect an area or asset from incoming threats, such as missiles or aircraft. The goal is to provide multiple opportunities to intercept and destroy a threat before it reaches its target.

TECHNICAL DEFINITION

Layered defense, also known as defense-in-depth, is a multi-tier military strategy employing diverse, integrated air and missile defense systems (e.g., long-range, medium-range, short-range interceptors, direct energy weapons) positioned across various operational domains and altitudes to provide redundancy and increase the probability of intercepting sophisticated aerial threats, thereby enhancing asset survivability.

BACKGROUND

A United States defense standard, often called a military standard, "MIL-STD", "MIL-SPEC", or (informally) "MilSpecs", is used to help achieve standardization objectives by the United States Department of Defense.
