National Defense Strategy

{{Short description|Current master plan for US military and counterterrorism contingency}} {{Use American English|date=February 2026}} {{Use mdy dates|date=February 2026}} The '''National Defense Strategy''' ('''NDS''') is produced by the United States Office of the Secretary of Defense (OSD) and is signed by the United States Secretary of Defense as the United States Department of Defense's (DoD) capstone strategic guidance. The NDS is required by law that mandates the secretary of defense to publish a "strategic framework" to address “priority missions of the Department of Defense” and the “assumed strategic environment.” It should “support the most recent National Security Strategy (NSS) report of the President." In theory, the NSS provides guidance for the DoD to outline military planning, military strategy, force posturing, force constructs, force modernization, etc. It is expected to be produced every four years, with an "unclassified summary" made available to the public.<ref name= ndsUnclNprMdr >Lloyd Austin III, US Secretary of Defense, et. al.

In any case, the NMS is a further refinement of the NDS to provide the U.S. military with more detailed guidance for theater campaign planning, modernization, force posturing, and force structure. NMS is often classified, while the NDS is not. By law, the Secretary of Defense has to release an unclassified summary of the classified version of the NDS.<ref name="ndsFact" /><ref>{{Cite web |date=28 March 2022 |title=Fact Sheet: 2022 National Defense Strategy |url=https://media.defense.gov/2022/Mar/28/2002964702/-1/-1/1/NDS-FACT-SHEET.PDF |access-date=29 March 2022 |website=United States Department of Defense |archive-date=March 28, 2022 |archive-url=https://web.archive.org/web/20220328213613/https://media.defense.gov/2022/Mar/28/2002964702/-1/-1/1/NDS-FACT-SHEET.PDF |url-status=live }}</ref> thumb|Report space on 2018, 2022, and 2026 NDS dedicated to major topics Each NDS emphasizes different issues areas, reflecting priorities that each administration identifies as the most important for the U.S. military to address.

In 2018, under the first Trump administration, the NDS became the sole successor to the Quadrennial Defense Review (QDR).<ref name="brookings2018">{{cite web|url=https://www.brookings.edu/blog/order-from-chaos/2018/01/21/how-to-read-the-2018-national-defense-strategy/|title=How to read the 2018 National Defense Strategy|last1=Karlin|first1=Mara|website=Brookings Institution|date=21 January 2018|accessdate=May 1, 2018|archive-date=April 23, 2019|archive-url=https://web.archive.org/web/20190423231743/https://www.brookings.edu/blog/order-from-chaos/2018/01/21/how-to-read-the-2018-national-defense-strategy/|url-status=live}}</ref><ref name="qdrDead">{{cite web|last1=Gould|first1=Joe|title=QDR Dead in 2017 Defense Policy Bill|url=https://www.defensenews.com/home/2016/04/25/qdr-dead-in-2017-defense-policy-bill/|website=Defense News|date=25 April 2016 |accessdate=May 1, 2018}}</ref><ref name="mattis2018">[https://hub.jhu.edu/2018/01/19/jim-mattis-unveils-new-national-defense-strategy/ Saralyn Cruickshank (Jan 19, 2018) U.S. Defense Secretary James Mattis outlines bold new national defense strategy at Johns Hopkins] {{Webarchive|url=https://web.archive.org/web/20190817044954/https://hub.jhu.edu/2018/01/19/jim-mattis-unveils-new-national-defense-strategy/ |date=August 17, 2019 }} #Updating nuclear command, control, and support infrastructure to better counter-attacks from U.S. adversaries #Prioritizing investments in space operations and capabilities #Integrating cyber defense into the full spectrum of military operations #Developing information systems that support the military's tactical operations, strategic planning, and intelligence gathering</ref> The 2018 NDS focused on great power competition with China and Russia and shifted attention away from counterterrorism.
