Radio Materiel School
The Radio Materiel School (RMS), operated by the United States Navy, was the first electronics training facility of America’s military organizations. During the 1920s and 1930s, it produced the core of senior maintenance specialists for the Navy’s communication equipment that “paved the way to United States world leadership in electronics.” Background Although Guglielmo Marconi demonstrated Morse-code radio communication to the U.S. Navy in late 1899, it was two years before the decision was made to adopt this technology. At that time, Chief Electricians James H. Bell and William C. Bean were sent to Europe to examine available equipment and its operation and maintenance, thereby becoming the first radio technicians in the U.S. Navy. The Navy purchased its first communication sets from foreign manufacturers, but these were soon replaced with American products. In the 1905-1916 period, the Navy continually expanded its radio communication capabilities. Stemming from the ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lieutenant (navy)
LieutenantThe pronunciation of ''lieutenant'' is generally split between , , generally in the United Kingdom, Ireland, and Commonwealth countries, and , , generally associated with the United States. See lieutenant. (abbreviated Lt, LT (U.S.), LT(USN), Lieut and LEUT, depending on nation) is a commissioned officer rank in many English-speaking nations' navies and coast guards. It is typically the most senior of junior officer ranks. In most navies, the rank's insignia may consist of two medium gold braid stripes, the uppermost stripe featuring an executive curl in many Commonwealth of Nations; or three stripes of equal or unequal width. The now immediately senior rank of lieutenant commander was formerly a senior naval lieutenant rank. Many navies also use a subordinate rank of sub-lieutenant. The appointment of "first lieutenant" in many navies is held by a senior lieutenant. This naval lieutenant ranks higher than an army lieutenants; within NATO countries the naval rank ...

Eddy Test
Eddy Test was the common name for a test given throughout World War II and for several years thereafter, to identifying men with the capability and aptitude for being trained in the enlisted ranks as electronics maintenance technicians in the U.S. Navy and U.S. Marine Corps. The official name was Radio Technician Selection Test (RTST, Nav Pers 16578), but this designation was rarely used. Passing the Eddy Test served as the passport to the Electronics Training Program, possibly the best technical training program then available in the armed services. Background Since 1924, the Radio Materiel School (RMS), located on the campus of the Naval Research Laboratory (NRL) in Washington, D.C., had provided advanced maintenance training for selected men with a rating of electrician's mate or radioman in the U.S. Navy and Coast Guard. Admission required years of experience as an apprentice (then called a "striker") and passing a very difficult examination. The RMS graduated about 100 men pe ...

Electronics Training Program
The Electronics Training Program (ETP) was the name commonly used for an unusual, difficult, and selective training activity of the United States Navy during World War II. The ETP combined college-level classroom instruction with laboratories involving highly complex electronic systems that were classified secret, resulting in a level of training reported to have been the most intense and difficult ever given to enlisted servicemen. A highly regarded Naval officer noted that the ETP graduates were in the top three to five percent of the Navy's wartime personnel, officers as well as enlisted men. Background As America entered WW II, there was a crisis concerning the availability of men qualified to maintain the huge amount of complex electronic equipment being procured for the Navy's ships, aircraft, submarines, and shore stations. The Navy had over 200,000 personnel, but only a few hundred were radio technicians, most having obtained their qualification through self-study and on ...

Bureau Of Navigation
The Bureau of Navigation, later the Bureau of Navigation and Steamboat Inspection and finally the Bureau of Marine Inspection and Navigation — not to be confused with the United States Navys Bureau of Navigation — was an agency of the United States Government established in 1884 to enforce laws relating to the construction, equipment, operation, inspection, safety, and documentation of merchant vessels. The bureau also investigated marine accidents and casualties; collected tonnage taxes and other navigation fees; and examined, certified, and licensed merchant mariners. When established, the Bureau of Navigation was a part of the United States Department of the Treasury. In 1903, the organization was transferred to the newly formed United States Department of Commerce and Labor. In 1913 that department was split into the United States Department of Commerce and the United States Department of Labor, and the bureau was assigned to the new Department of Commerce.

Slide Rule
The slide rule is a mechanical analog computer which is used primarily for multiplication and division, and for functions such as exponents, roots, logarithms, and trigonometry. It is not typically designed for addition or subtraction, which is usually performed using other methods. Maximum accuracy for standard linear slide rules is about three decimal significant digits, while scientific notation is used to keep track of the order of magnitude of results. Slide rules exist in a diverse range of styles and generally appear in a linear, circular or cylindrical form, with slide rule scales inscribed with standardized Graduation (instrument), graduated markings. Slide rules manufactured for specialized fields such as aviation or finance typically feature additional scales that aid in specialized calculations particular to those fields. The slide rule is closely related to nomograms used for application-specific computations. Though similar in name and appearance to a standard ruler ...

USS Saratoga (CV-3)
USS ''Saratoga'' (CV-3) was a built for the United States Navy during the 1920s. Originally designed as a battlecruiser, she was converted into one of the Navy's first aircraft carriers during construction to comply with the Washington Naval Treaty of 1922. The ship entered service in 1928 and was assigned to the Pacific Fleet for her entire career. ''Saratoga'' and her sister ship, , were used to develop and refine carrier tactics in a series of annual exercises before World War II. On more than one occasion these exercises included successful surprise attacks on Pearl Harbor, Hawaii. She was one of three prewar US fleet aircraft carriers, along with and , to serve throughout World War II. Shortly after the Japanese attack on Pearl Harbor, ''Saratoga'' was the centerpiece of the unsuccessful American effort to relieve Wake Island and was torpedoed by a Japanese submarine a few weeks later. After lengthy repairs, the ship supported forces participating in the Guadalcanal Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
