ships in violation of treaty limits, yet secretly building the Yamato class battleshipand re-boilering older vessels behind large screens at their building docks. 23Given this dearth of information, ONI analysts and collectors naturally appliedtheir biases to assessments of Japanese capabilities, erroneously evaluating thequality of the Japanese naval fleet and their naval air forces as low. 24Despite the lack of success against the Japanese target, ONI’s other HUMINToperations were more profitable. The American Legation, United States NavalAttaché, London (ALUSNA London), which will be discussed extensively inchapter 5, was a critical node for the flow of intelligence and technical informationinto ONI. ONI attachés in Latin America also had considerable successes inproviding worthwhile intelligence and countering the moves of Axis intelligenceoperatives and subversive elements in the countries to which they wereassigned. 25 By June of 1940, the Navy also took steps to strengthen its clandestineHUMINT capabilities and had relatively good success with these assets inNorth Africa and Mexico, although this capability would be absorbed by theCoordinator of Information (COI) the following year. 26SIGINT was also a major source of intelligence for ONI. The first Navy HighFrequency Direction Finding (HF/DF) sites were established in 1918 and the U.S.had some success against foreign codes during the 1920s and 30s. 27 By the1930s, the Navy and the Army had three major cryptologic collection siteslocated at Corregidor (Cavite or Station CAST) in the Philippines, Pearl Harbor,and Washington, DC. 28 The collection and decryption of the intercepted communicationswas handled by Director of Naval Communications OP-20-G, the“Communications Security Section,” while much of the translation and analysisof the decrypted communications was handled by ONI. 29 While the Navy’s cryptanalyticsection was several times larger than the Army’s at the start of the war,at around 147 personnel, the Navy had negligible success against the main Japanesenaval code, designated JN-25, until just before the war, when cooperationwith British communications intelligence (COMINT) personnel became morecommon. 30 Although information gathered from the Japanese diplomatic codewas an important source of intelligence, it contained virtually no military infor-23Malcolm Muir, Jr., “Rearming in a Vacuum: United States Navy <strong>Intelligence</strong> and the JapaneseCapital Ship Threat, 1936-1945,” The Journal of Military History 54, no. 4 (October 1990): 473-477.24Muir, 478-479; Dorwart, Conflict of Duty, 27-29.25Dorwart, Conflict of Duty, 106-109.26 Packard, 130.27 Aldrich, 33.28 Worth, 11-12.29Jeffrey K.

mation and it was only distributed to a chosen few, which limited its utility as asource of information to inform operational planners and tactical forces.Internecine Conflict and Its Effect on ONIPatrick Beesly, who worked in the British Admiralty’s Operational <strong>Intelligence</strong>Center (OIC) during World War II, has noted that one of the main deficiencies ofONI was its lack of any capability to provide operational intelligence (OPINTEL)support. He notes that the roots of this problem lay in World War I, when theNaval <strong>Intelligence</strong> Division (NID) of legendary British Rear Admiral Sir Reginald“Blinker” Hall, rather than ONI, provided the intelligence for the British andAmerican operating forces. While the Royal Navy allowed its OPINTEL capabilityto lapse in the interwar period, it was able to reconstitute it quickly owing tothe tradition initiated by Hall, whereas ONI had no such tradition to fall backon. 31 Another major difference between the NID and ONI, however, was that, onthe eve of the war, ONI lacked direct access to key policymakers whereas theNID had direct access to the senior civilian and military leaders of the RoyalNavy (the First Lord and the First Sea Lord of the Admiralty). 32 For the Americans,this situation also had its roots in the U.S. Navy’s World War I experienceand was largely a function of the personalities at the top of the Navy’s hierarchy.In August 1939, Admiral William Leahy was relieved by Admiral Harold“Betty” Stark as the Chief of Naval Operations (CNO). Stark was an officer inAdmiral William Sims’ planning cell during World War I and his ideas on howbest to plan for naval operations were formed from that experience. ADM Simshad essentially created a miniature ONI to support planning done by his staff inLondon. For this reason, Stark accepted a model proposed by the Director ofNaval War Plans, Rear Admiral Richmond Kelly Turner, which gave the WarPlans Division the primary responsibility for evaluating intelligence. 33 Turner’sreasoning was based on the fact that an intelligence assessment might cause anoperational commander to take a specific course of action and, since potentialship movements fell under the purview of operators, they should have the finalcheck on intelligence. Thus, in the period just prior to the war, the War PlansDivision had primary responsibility for producing and disseminating intelligence31 Patrick Beesly, Very Special <strong>Intelligence</strong>: The Story of the Admiralty’s Operational <strong>Intelligence</strong>Center 1939-1945 (Garden City, NY: Doubleday & Company, INC., 1977), 111-112.
