The Defense Threat Reduction Agency

(DTRA) was established in 1998 and

is under the authority, direction, and

control of the Under Secretary of

Defense for Acquisition, Technology, and

Logistics. DTRA’s mission is to reduce

the threat posed by weapons of mass

destruction (WMD). DTRA covers the

full range of WMD threats (chemical,

biological, nuclear, radiological, and high

explosive), bridges the gap between the

warf‌i ghters and the technical community,

sustains the nuclear deterrent, and

provides both offensive and defensive

technology and operational concepts

to warf‌i ghters. DTRA reduces the threat

of WMD by implementing arms control

treaties and executing the Cooperative

Threat Reduction Program. It uses combat

support, technology development, and

chemical-biological defense to deter

the use and reduce the impact of such

weapons. DTRA also prepares for future

threats by developing the technology and

concepts needed to counter new WMD

threats and adversaries.

The Missile Defense Agency’s (MDA)

mission is to establish and deploy a

layered ballistic missile defense system

to intercept missiles in all phases of

their f‌l ight and against all ranges of

threats. This capability will provide a

defense of the United States, deployed

forces, and allies. MDA is under the

authority, direction, and control of

the Under Secretary of Defense for

Acquisition, Technology, and Logistics.

MDA manages and directs DOD’s

ballistic missile defense acquisition

programs and enables the Services to

f‌i eld elements of the overall system as

soon as practicable. MDA develops and

tests technologies and, if necessary, uses

prototype and test assets to provide early

capability. Additionally, MDA improves

the effectiveness of deployed capabilities

by implementing new technologies as

they become available or when the threat

warrants an accelerated capability.
