Chief of Naval Operations
The chief of naval operations (CNO) is the professional head of the United States Navy. The position is a statutory office (10 U.S.C. § 8033) held by an admiral who is a military adviser and deputy to the secretary of the Navy. In a separate capacity as a member of the Joint Chiefs of Staff (10 U.S.C. § 151), the CNO is a military adviser to the National Security Council, the Homeland Security Council, the secretary of defense, and the president. The current chief of naval operations is Admiral Michael M. Gilday.

Despite the title, the CNO does not have operational command authority over naval forces. The CNO is an administrative position based in the Pentagon, and exercises supervision of Navy organizations as the designee of the secretary of the Navy. Operational command of naval forces falls within the purview of the combatant commanders who report to the secretary of defense.
Appointment, rank, and responsibilitiesEdit
The chief of naval operations (CNO) is typically the highest-ranking officer on active duty in the U.S. Navy unless the chairman and/or the vice chairman of the Joint Chiefs of Staff are naval officers. The CNO is nominated by the president for the appointment and must be confirmed by the Senate. A requirement for being Chief of Naval Operations is having significant experience in joint duty assignments, which includes at least one full tour of duty in a joint duty assignment as a flag officer. However, the president may waive those requirements if he determines that appointing the officer is necessary for the national interest. By statute, the CNO is appointed as a four-star admiral.
As per 10 U.S.C. § 8035, whenever there is a vacancy for the chief of naval operations or during the absence or disability of the chief of naval operations, and unless the president directs otherwise, the vice chief of naval operations performs the duties of the chief of naval operations until a successor is appointed or the absence or disability ceases.
The CNO also performs all other functions prescribed under 10 U.S.C. § 8033, such as presiding over the Office of the Chief of Naval Operations (OPNAV), exercising supervision of Navy organizations, and other duties assigned by the secretary or higher lawful authority, or the CNO delegates those duties and responsibilities to other officers in OPNAV or in organizations below.
Acting for the secretary of the Navy, the CNO also designates naval personnel and naval forces available to the commanders of unified combatant commands, subject to the approval of the secretary of defense.
Joint Chiefs of StaffEdit
The CNO is a member of the Joint Chiefs of Staff as prescribed by 10 U.S.C. § 151 and 10 U.S.C. § 8033. Like the other members of the Joint Chiefs of Staff, the CNO is an administrative position, with no operational command authority over the United States Navy forces.
Members of the Joint Chiefs of Staff, individually or collectively, in their capacity as military advisers, shall provide advice to the president, the National Security Council (NSC), or the secretary of defense (SECDEF) on a particular matter when the president, the NSC, or SECDEF requests such advice. Members of the Joint Chiefs of Staff (other than the chairman of the Joint Chiefs of Staff) may submit to the chairman advice or an opinion in disagreement with, or advice or an opinion in addition to, the advice presented by the chairman to the president, NSC, or SECDEF.
When performing his JCS duties, the CNO is responsible directly to the SECDEF, but keeps SECNAV fully informed of significant military operations affecting the duties and responsibilities of the SECNAV, unless SECDEF orders otherwise.
Early attempts (1902–1909)Edit
The earliest attempts to reform the Navy's management structure under a single commissioned officer began in response to President Theodore Roosevelt's massive buildup of naval power, in concert with his "Big Stick" implementation of foreign policy. The closest thing the Navy had to an executive body at the time was the General Board of the United States Navy, established in 1900, but the Board lacked the necessary authority to sufficiently reorganize the Navy. Among the critics of the disorganized command structure and proponents of rapid modernization included Charles J. Bonaparte, Roosevelt's fourth Navy secretary from 1905 to 1906, Reginald R. Belknap, Albert Key, and William Sims, Roosevelt's naval aides from 1905 to 1907 and 1907 to 1909 respectively.
Rear Admiral George A. Converse, commander of the Bureau of Navigation (BuNav) from 1905 to 1906, reported:
[W]ith each year that passes the need is painfully apparent for a military administrative authority under the Secretary, whose purpose would be to initiate and direct the steps necessary to carry out the Department’s policy, and to coordinate the work of the bureaus and direct their energies toward the effective preparation of the fleet for war.
However, proposals to establish a permanent body to manage the disparate bureaus and offices faced vehement disapproval from Congress, partially due to fears of creating a Prussian-style general staff and because several of such proposals granted greater authority to the secretary of the Navy over the officer promotion system, both of which risked infringing on legislative authority. In particular, Senator Eugene Hale, chairman of the Senate Committee on Naval Affairs from 1897 to 1909, disliked reformers like Sims and persistently blocked attempts to bring such ideas for debate, including those of a special board convened by Roosevelt in 1909 which supported immediate change.
To circumvent the opposition, George von Lengerke Meyer, Secretary of the Navy under Roosevelt's successor William Howard Taft implemented a system of "aides" on 18 November 1909, including aides for personnel, material, inspections, and operations. These four senior officers, with the rank of rear admiral, did not have command authority and instead served as principal advisors to the Secretary, charged with supervising and coordinating the functions of their respective bureaus. Meyer deemed the aide for operations to be the most important of the four, responsible for devoting "his entire attention and study to the operations of the fleet," and drafting orders for the movement of ships on the advice of the General Board and approval of the Secretary in times of war or emergency.
The first aide for operations was Rear Admiral Richard Wainwright, who immediately exercised the influence he had to recommend significant reorganization of the Atlantic and Pacific Fleets to better fit contemporary mission needs. The effectiveness of the arrangement factored into Meyer's decision to grant his newly appointed third aide for operations, Rear Admiral Bradley A. Fiske, de facto status as his principal advisor on 10 February 1913. Fiske retained his post under Meyer's successor, Josephus Daniels.
It was under Secretary Daniels and Admiral Fiske that efforts to definitively establish a professional head of the Navy began. Daniels and Fiske, however, often clashed, and their contrasting temperaments often led to debates by both Congress and the executive branch as to whose vision for the Navy was more effective based on individual like or dislike for one or the other. Consequently, the legislation providing for the office of "a chief of naval operations" in 1914 was the result of Fiske going behind Daniels' back, frustrated at the Secretary's ambivalence towards his assertions that the Navy was unprepared for the possibility of being "drawn into" World War I. Early forms of the legislation were the product of Fiske's collaboration with Representative Richmond P. Hobson, a retired Navy admiral. The preliminary proposal (passed off as Hobson's own to mask Fiske's involvement), in spite of Daniels' opposition, passed Hobson's subcommittee unanimously on 4 January 1915, and passed the full House Committee on Naval Affairs on 6 January.
Fiske's younger supporters expected him to be named the first chief of naval operations, and his versions of the bill presented for passage in the Senate provided for the minimum of rank of the officeholder to be a two-star rear admiral.
There shall be a Chief of Naval Operations, who shall be an officer on the active list of the Navy not below the grade of Rear Admiral, appointed for a term of four years by the President, by and with the advice of the Senate, who, under the Secretary of the Navy, shall be responsible for the readiness of the Navy for war and be charged with its general direction.— Fiske's version of the bill
In contrast, Daniels' version, included in the final bill, emphasized the office's subordination to the secretary of the Navy, allowed for the selection of the CNO from officers of the rank of captain, and denied it authority over the Navy's general direction, tantamount to giving the CNO executive authority:
There shall be a Chief of Naval Operations, who shall be an officer on the active list of the Navy appointed by the President, by and with the advice and consent of the Senate, from the officers of the line of the Navy not below the grade of Captain for a period of four years, who shall, under the direction of the Secretary, be charged with the operations of the fleet, and with the preparation and readiness of plans for its use in war.— Daniels' version of the bill
Fiske's "end-running" of the secretary, while successful in enshrining a professional head of the Navy within statutory law, had permanently tarnished him as insubordinate to Daniels, and eliminated any possibility of him being named the first CNO. Nevertheless, Fiske, satisfied with the change he had helped enact, made a final contribution: elevating the statutory rank of the CNO to admiral with commensurate pay. The Senate passed the appropriations bill creating the CNO position and its accompanying office on 3 March 1915. Simultaneously, the system of naval aides promulgated under Meyer was also abolished. Fiske himself retired in 1916, after a year's tour at the Naval War College.
Benson, the first CNOEdit
Captain William S. Benson was promoted to the temporary rank of rear admiral and become the first CNO on 11 May 1915. He further assumed the rank of admiral after the passage of the 1916 Naval Appropriations Bill with Fiske's amendments, second only at the time of passage to Admiral of the Navy George Dewey, and explicitly superior to the commanders-in-chief of the Atlantic, Pacific and Asiatic Fleets.
CNO Benson faced three principal tasks: defining where the chief of naval operations stood within the command hierarchy, forging a productive working relationship with and demonstrating loyalty to Secretary Daniels, and preparing the Navy for potential involvement in World War I without violating the government's official policy of neutrality. Benson thus differed from his predecessor Fiske who campaigned for a powerful, aggressive CNO sharing authority with the secretary of the Navy by demonstrating personal loyalty to the secretary and subordinating himself to civilian control in all matters, thereby alienating reformers like Sims. At the same time, this gave Daniels immense trust in his new CNO, especially in dealing with more troublesome officers like Fiske and Sims on a daily basis, and he rewarded Benson by delegating greater resources and authority to the CNO.
Nevertheless, this did not stop him from maintaining a need for autonomy when he felt it necessary. Benson also intended to disprove those of the officer corps who "spent much of their time criticizing him" for pacifist views perceived to be shared with President Woodrow Wilson, who proclaimed a policy of neutrality in World War I in August 1914.
Among the organizational efforts initiated or recommended by Benson included an advisory council to coordinate high-level staff activities, composed of himself, the SECNAV and the bureau chiefs which "worked out to the great satisfaction" of Daniels and Benson; the reestablishment of the Joint Army and Navy Board in 1918 with Benson as its Navy member; and the consolidation of all matters of naval aviation under the authority of the CNO. In all these efforts, Benson remained subordinate to the secretary of the Navy while still being involved in all important decisions affecting the Navy. Benson also had the task of assisting Secretary Daniels with the modernization of the Navy, specifically through advising him of developments in naval technologies and ships.
Most importantly for the future war, Benson revamped the structure of the naval districts, transferring authority for them from SECNAV to the Office of the Chief of Naval Operations under the Operations, Plans, Naval Districts division. This enabled closer cooperation between naval district commanders and the uniformed leadership, who could more easily handle communications between the former and the Navy's fleet commanders.
World War I and the establishment of OPNAVEdit
Early 1916 saw the formal establishment of the CNO's "general staff", the Office of the Chief of Naval Operations (OPNAV), originally called the Office for Operations. Until then, the CNO's office was assigned few personnel: three subordinates (one captain and two lieutenants), no clerical staff, and small, unaccommodating office space on the first day of Benson's tenure. With Hale's retirement from politics in 1911, congressional opinion shifted from fear of a Prussian-style general staff to skepticism of whether the CNO's staff could implement President Wilson's policy of "preparedness" within the limits of official neutrality. This apprehension would persist for the entirety of Benson's tenure, as even in January 1917, the personnel in OPNAV still numbered only 75, barely adequate for Benson's needs.
OPNAV saw a significant increase in size following American entry into World War I, as it was deemed of great importance to manage the rapid mobilization of forces to fight in the war. Among the tasks OPNAV was charged with included specifying the wartime responsibilities of the naval districts, sourcing and producing enough transports for the Army divisions being transferred to the war's western front, and coordinating convoy escorts with the British. The 75 initially assigned to OPNAV in 1917 had ballooned to over 1462 by war's end. This caused the CNO and OPNAV to gain great influence over Navy administration but at the expense of the General Board, which had little power to begin with, and more importantly, at the expense of the secretary and naval bureaus.
Advisor to the presidentEdit
Benson also demonstrated the usefulness of the CNO as a direct advisor to the President of the United States on matters outside of the United States Navy relating to larger diplomatic and strategic concerns. In 1918, Benson became a military advisor to Edward M. House, an advisor and confidant of President Wilson, joining him on a trip to Europe as the 1918 armistice with Germany was signed. His stance that the United States remain equal to Great Britain in naval power proved very useful to House and Wilson, enough for Wilson to insist Benson remain in Europe until after the Treaty of Versailles was signed in July 1919.
End of tenureEdit
Benson's tenure as chief of naval operations was slated to end on 10 May 1919, but this was delayed by the president at Secretary Daniels's insistence. In the waning years of his tenure, Benson presided over a final reorganization of OPNAV, focusing on preventing feuds between the different divisions and setting regulations for officers on shore duty to have temporary assignments with OPNAV, so as to maintain cohesion between the higher-level staff and the fleet. Thus, Admiral Benson retired on 25 September 1919 having reformed the Navy's leadership structure, and with his involvement with President Wilson and House on the Treaty of Versailles demonstrated the usefulness of the CNO as a presidential advisor on strategic and diplomatic matters. Admiral Robert Coontz replaced Benson as CNO on 1 November 1919.
Interwar period (1919–1939)Edit
The CNO's office faced no significant changes in authority during the interwar period, largely due to the secretaries of the Navy opting to keep executive authority within their own office. Innovations during this period included encouraging coordination in war planning process, and compliance with the Washington Naval Treaty while still keeping to the shipbuilding plan authorized by the Naval Act of 1916. and implementing the concept of naval aviation into naval doctrine.
William V. Pratt became the fifth Chief of Naval Operations on 17 September 1930. He had previously served as assistant chief of naval operations under CNO Benson, and had proven pivotal to bridging the gap between Benson and Daniels with equal experience as a protégé of Vice Admiral Sims, whose outspokenness regarding wartime deficiencies and the power granted to the CNO earned him a poor reputation among higher-ups in the Department of the Navy and OPNAV. A premier naval policymaker and supporter of arms control under the Washington Naval Treaty, Pratt clashed with President Herbert Hoover over building up naval force strength to treaty levels, with Hoover favoring restrictions in spending due to financial difficulties caused by the Great Depression.
Pratt opposed centralized management of the Navy, and encouraged diversity of opinion between the offices of the Navy secretary, CNO and the Navy's General Board. To this effect, Pratt removed the CNO as an ex officio member of the General Board, concerned that the office's association with the Board could hamper diversities of opinion between the former and counterparts within the offices of the Navy secretary and OPNAV. This was in conflict with the powerful Representative Carl Vinson of Georgia, chair of the House Naval Affairs Committee from 1931 to 1947, who deliberately delayed many of his planned OPNAV reorganization proposals until Pratt's replacement by William H. Standley to avoid the unnecessary delays that would otherwise have happened with Pratt.
Pratt also enjoyed a good working relationship with Army chief of staff Douglas MacArthur, and negotiated several key agreements with him over coordinating their services' radio communications networks, mutual interests in coastal defense, and authority over Army and Navy aviation.
Standley and Leahy, preparing for warEdit
William H. Standley, Pratt's successor, had a weaker relationship with President Franklin D. Roosevelt than Pratt with Hoover, and was often in direct conflict with secretary of the Navy Claude A. Swanson and assistant secretary Henry L. Roosevelt. In fact, Standley's hostility to the assistant secretary was even described as "poisonous". On ther other hand, Standley successfully improved relations with Congress, streamlining communications between the Department of the Navy and the naval oversight committees by appointing the first naval legislative liaisons, the highest-ranked of which reported to the judge advocate general. Most importantly, Standley worked with Representative Vinson to pass the Vinson-Trammell Act, considered by Standley to be his most important achievement as CNO. The Act authorized the President:
“to suspend” construction of the ships authorized by the law “as may be necessary to bring the naval armament of the United States within the limitation so agreed upon, except that such suspension shall not apply to vessels actually under construction on the date of the passage of this act.”
This effectively provided security for all Navy vessels under construction; even if new shipbuilding projects could not be initiated, shipbuilders with new classes under construction could not legally be obliged to cease operations, which consequently allowed the Navy to adequately prepare for World War II without breaking potential limits imposed by future arms control conferences. The Act also granted the CNO soft oversight power of the naval bureaus which nominally lay with the secretary of the Navy as Standley gradually inserted OPNAV into the ship design process.
Number One Observatory Circle, located on the northeast grounds of the United States Naval Observatory in Washington, DC, was built in 1893 for its superintendent. The chief of naval operations liked the house so much that in 1923 he took over the house as his own official residence. It remained the residence of the CNO until 1974, when Congress authorized its transformation to an official residence for the vice president. The chief of naval operations currently resides in Quarters A in the Washington Naval Yard.
The chief of naval operations presides over the Navy Staff, formally known as the Office of the Chief of Naval Operations (OPNAV). The Office of the Chief of Naval Operations is a statutory organization within the executive part of the Department of the Navy, and its purpose is to furnish professional assistance to the secretary of the Navy (SECNAV) and the CNO in carrying out their responsibilities.
Under the authority of the CNO, the director of the Navy Staff (DNS) is responsible for day-to-day administration of the Navy Staff and coordination of the activities of the deputy chiefs of naval operations, who report directly to the CNO. The office was previously known as the assistant vice chief of naval operations (AVCNO) until 1996, when CNO Jeremy Boorda ordered its redesignation to its current name. Previously held by a three-star vice admiral, the position became a civilian's billet in 2018. The present DNS is Andrew S. Haueptle, a retired Marine Corps colonel.
