We want warriors, folks that understand how to exact lethality on the enemy,\u201d <a href=\"https:\/\/www.foxnews.com\/politics\/trump-rename-pentagon-restoring-historic-department-war-latest-military-move\" rel=\"\">Secretary of Defense Pete Hegseth told \u201cFox &amp; Friends\u201d<\/a> several days later.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe don\u2019t want endless contingencies and just playing defense,\u201d he continued. \u201cWe think words and names and titles matter. So, we\u2019re working with the White House and the president on it. Stand by.\u201d <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Origins of the War Department<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In 1789, President George Washington signed legislation to create America\u2019s first iteration of the War Department. Under Henry Knox, the first secretary of war, the Department of War replaced the wartime Board of War and Ordnance, which was established under Washington in 1776.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"about:blank\" rel=\"\">The act<\/a> was responsible for \u201cfor military commissions, land and naval forces, warlike stores, Indian affairs, and granting lands for military services.\u201d However, the War Department primarily oversaw the Army, with the Navy getting its own Cabinet-level department less than a decade later \u2014 which also oversaw the Marines.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That structure remained in place until 1947, when President Harry Truman received approval from Congress to create a National Defense Establishment. The NDE eventually took power from the Army and Navy, as well as the newly formed Air Force.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It was, <a href=\"https:\/\/www.airandspaceforces.com\/article\/0799coup\/\" rel=\"\">writes Air and Space Forces Magazine<\/a>, \u201ca landmark in the organization of America\u2019s military establishment.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Just a few months after the conclusion of World War II, Truman announced his goal to implement a new governing structure for the military, as the war had induced a need for a more codified command structure. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In a <a href=\"https:\/\/www.trumanlibrary.gov\/library\/public-papers\/218\/special-message-congress-recommending-establishment-department-national\" rel=\"\">special message to Congress on Dec. 19, 1945<\/a>, Truman stated:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n\n<p class=\"wp-block-paragraph\">\u201cI recommend that the Congress adopt legislation combining the War and Navy Departments into one single Department of National Defense. Such unification is another essential step \u2014 along with universal training \u2014 in the development of a comprehensive and continuous program for our future safety and for the peace and security of the world.<\/p>\n\n\n<p class=\"wp-block-paragraph\">One of the lessons which have most clearly come from the costly and dangerous experience of this war is that there must be unified direction of land, sea and air forces at home as well as in all other parts of the world where our Armed Forces are serving.<\/p>\n\n\n<p class=\"wp-block-paragraph\">We did not have that kind of direction when we were attacked four years ago \u2014 and we certainly paid a high price for not having it.&#8221;<\/p>\n\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Cognizant of the potential pushback from the Army and Navy and its generals who might view the proposal as a threat to their service\u2019s autonomy, Truman wrote in a White House press release on April 5, 1946, \u201cUnification does not mean subordination of any branch of the service. It does not mean a loss of identity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIt means just what the word says \u2014 unification. It means a concentration and cohesion of our best military thought and our best military resources, geared to maximum efficiency. It means using our experience in World War II for the peace of the world.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, Truman\u2019s words of pacification did little to placate certain members of the Navy. In 1949, a small group of senior Navy officers took their private feud with the Army and Air Force public, calling into question the strategy to defeat a Soviet invasion of Europe and the allocation of scarce budget dollars, according to the <a href=\"https:\/\/www.usni.org\/magazines\/proceedings\/2020\/september\/revolt-admirals-and-todays-battle-over-defense-budget\" rel=\"\">U.S. Naval Institute<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The resulting civilian-military dustup, dubbed the \u201cRevolt of the Admirals\u201d would later involve two congressional hearings and amendments to the National Security Act of 1947 \u201cthat decisively shaped the character and organization of the military for the next half century,\u201d according to the Air and Space Forces Magazine. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Revolt of the admirals<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The cause for the revolt was twofold, arising from both a mismatch between the United States\u2019 expansive postwar conception of its national security and the demands for fiscal orthodoxy, according to the U.S. Naval Institute. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In a tale as old as time, senior officials wanted a global presence in the wake of World War II \u2014 but didn\u2019t want to pay for it. The Truman administration was determined to hold the defense budget to about $13 billion per year. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That relatively tight budget was split into thirds \u2014 one slice each for the land, air and the sea. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThis intensified the roles-and-missions struggle,\u201d writes the Institute. \u201cThe Navy thought it was in danger of losing its air arm to the Air Force. The Air Force was convinced that the Navy was attempting to build a strategic air force of its own.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to <a href=\"https:\/\/www.usni.org\/magazines\/proceedings\/2020\/september\/revolt-admirals-and-todays-battle-over-defense-budget\" rel=\"\">historian Anand Toprani<\/a>, there were two stages of the revolt. In the first, a civilian employee of the Navy (and a naval reservist) fabricated and then leaked to a sympathetic congressman (a retired reservist) an \u201cAnonymous Document\u201d accusing then Secretary of Defense Louis Johnson and Air Force Secretary Stuart Symington of corruption for favoring the procurement of the B-36 heavy bomber. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The publication of the document resulted in the first of two congressional hearings in August of 1949, which ultimately vindicated Johnson and Symington \u2014 much to the embarrassment of the Navy. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The second stage, according to Toprani, involved a Navy officer attached to the Joint Staff releasing an \u201cinternal Navy correspondence alleging that Johnson\u2019s policies \u2014 including the cancellation of the first \u2018supercarrier\u2019 [USS United States (CVA-58)] back in April \u2014 were harmful to the Navy\u2019s morale and detrimental to national security.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The correspondence led to senior Navy officers publicly breaking with Johnson and Symington, describing the Air Force\u2019s \u201cfetish\u201d for strategic bombing against the Soviet Union as immoral and ineffective.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Creation of the DOD<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In light of this \u201crevolt,\u201d several amendments to the National Security Act were implemented, converting the National Military Establishment into the Department of Defense.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"3000\" height=\"2376\" src=\"\/wp-content\/uploads\/2026\/08\/AP491109047.jpg.jpg\" alt=\"\" class=\"wp-image-110102\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/AP491109047.jpg.jpg 3000w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/AP491109047.jpg.jpg?resize=300,238 300w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/AP491109047.jpg.jpg?resize=768,608 768w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/AP491109047.jpg.jpg?resize=1024,811 1024w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/AP491109047.jpg.jpg?resize=1536,1217 1536w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/AP491109047.jpg.jpg?resize=2048,1622 2048w\" sizes=\"auto, (max-width: 3000px) 100vw, 3000px\" \/><figcaption class=\"wp-element-caption\">Defense Secretary Louis Johnson (right) gives a new identification card to President Harry Truman at the White House on Nov. 9, 1949, in Washington, listing him as commander in chief for an &#8220;indefinite&#8221; term.

The secretary of defense gained complete \u201cdirection, authority, and control\u201d over the entire department, becoming the \u201cprincipal assistant to the President in all matters relating to the Department of Defense.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, changes to the National Security Act included the creation of a chairman of the Joint Chiefs of Staff, who would directly advise both the president and the secretary of defense. Gen. Omar Bradley became the first chairman in 1949.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe finally succeeded,\u201d <a href=\"https:\/\/www.airandspaceforces.com\/article\/0799coup\/\"

the use of the Department of War name, albeit as a \u201csecondary title\u201d for the Department of Defense. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As it stands, only an act of Congress can
