This is a manual and schematics for the Grunow radio Chassis Type 12A, Receiver Model 1241 and type 487A Megohmmeter. This comes in the original envelope from the Department of the Navy. Date stamped October 6 1944.
The Navy traces its origins to the Continental Navy, which was established during the American Revolutionary War (1775 1783) in Beverly, Massachusetts[citation needed] and was essentially disbanded as a separate entity shortly thereafter. The United States Constitution provided the legal basis for a military force by giving Congress the power "to provide and maintain a navy".[5]
The 21st century United States Navy maintains a sizable global presence, deploying in such areas as East Asia, the Mediterranean, and the Middle East. It is a blue water navy with the ability to project force onto the littoral regions of the world, engage in forward areas during peacetime, and rapidly respond to regional crises, making it an active player in American foreign and defense policy.
The Navy is administratively managed by the Department of the Navy, which is headed by the civilian Secretary of the Navy. The Department of the Navy is itself a division of the Department of Defense, which is headed by the Secretary of Defense. The highest ranking Naval officer is the Chief of Naval Operations.

The mission of the Navy is to maintain, train and equip combat-ready Naval forces capable of winning wars, deterring aggression and maintaining freedom of the seas. Mission statement of the United States Navy[7]
From the New Recruits Handbook:
The mission of the United States Navy is to protect and defend the right of the United States and our allies to move freely on the oceans and to protect our country against her enemies.
The United States Navy serves as a seaborne branch of the Military of the United States. 10 U.S.C. 5062 prescribes the navy's three primary areas of responsibility:
* "The preparation of naval forces necessary for the effective prosecution of war"
* "The maintenance of naval aviation, including land-based naval aviation, air transport essential for naval operations and all air weapons and air techniques involved in the operations and activities of the Navy"
* "The development of aircraft, weapons, tactics, technique, organization, and equipment of naval combat and service elements".
U.S. Navy training manuals state the mission of the U.S armed forces is "to prepare and conduct prompt and sustained combat operations in support of the national interest". As part of that establishment, the U.S. Navy's functions comprise sea control, power projection and nuclear deterrence, in addition to "sealift" duties.[8]
Main article: History of the United States Navy
Without a decisive naval force we can do nothing definitive. George Washington[9]
The Continental Navy achieved mixed results; it was successful in a number of engagements and raided many British merchant vessels, but it lost 24 of its vessels[12] and at one point was reduced to two in active service.[13] As Congress turned its attention after the conflict towards securing the western border of the new United States, a standing navy was considered to be dispensable because of its high operating costs and its limited number of roles.[6]
[edit] From reestablishment to the Civil War
We ought to begin a naval power, if we mean to carry on our commerce. Thomas Jefferson[14]
USS Constitution battles HMS Guerriere in the War of 1812.
During the Mexican-American War the U.S. Navy contributed by instituting blockades of Mexican ports, capturing or burning the Mexican fleet in the Gulf of California and capturing all major cities in Baja California peninsula later returned. In 1846-1848 the navy successfully used the Pacific Squadron under Commodore (Rear Admiral) Robert Stockton and its marines and blue-jackets to facilitate the capture of California with large scale land operations coordinated with the local militia organized in the California Battalion. The navy conducted the U.S. military's first large-scale amphibious joint operation by successfully landing 12,000 army troops with their equipment in one day at Veracruz, Mexico. When larger guns were needed to bombard Veracruz Navy volunteers landed large navy guns and manned them in the successful bombardment of the city and its surrender. This successful landing and capture of Veracruz eventually opening the way for the capture of Mexico City and the end of the war.[6] The United States Navy established itself as a player in American foreign policy through the actions of Commodore Matthew Perry in Japan, which resulted in the Convention of Kanagawa in 1854.

The Navy was a major participant in the Vietnam War, blockaded Cuba during the Cuban Missile Crisis, and, through the use of ballistic missile submarines, became an important aspect of the United States' nuclear strategic deterrence policy. The United States Navy conducted various combat operations in the Persian Gulf against Iran in 1987 and 1988, most notably Operation Praying Mantis. The Navy was extensively involved in Operation Urgent Fury, Operation Desert Shield, Operation Desert Storm, Operation Deliberate Force, Operation Allied Force, Operation Desert Fox and Operation Southern Watch.
When a crisis confronts the nation, the first question often asked by policymakers is: 'What naval forces are available and how fast can they be on station?' Admiral Carlisle A. H. Trost[21]
In 2007, the U.S. Navy joined with the U.S. Marine Corps and U.S. Coast Guard to adopt a new maritime strategy called A Cooperative Strategy for 21st Century Seapower that raises the notion of prevention of war to the same philosophical level as the conduct of war. The strategy was presented by the Chief of Naval Operations, the Commandant of the Marine Corps and Commandant of the Coast Guard at the International Seapower Symposium in Newport, R.I. on 17 October 2007.[23] The strategy recognized the economic links of the global system and how any disruption due to regional crises man made or natural can adversely impact the U.S. economy and quality of life. This new strategy charts a course for the Navy, Coast Guard and Marine Corps to work collectively with each other and international partners to prevent these crises from occurring or reacting quickly should one occur to prevent negative impacts on the United States.

Main articles: United States Navy operating forces organization and List of units of the United States Navy
The United States Navy has six active numbered fleets Second, Third, Fifth, Sixth, and Seventh Fleets are each led by a three-star vice admiral, and the Fourth Fleet is led by a rear admiral. These six fleets are further grouped under Fleet Forces Command (the former Atlantic Fleet), Pacific Fleet, Naval Forces Europe, and Naval Forces Central Command, whose commander also doubles as Commander Fifth Fleet; the first three commands being led by four-star full Admirals. The First Fleet existed after the Second World War from 1947, but it was redesignated Third Fleet in early 1973.[24] In early 2008, the United States Navy reactivated the Fourth Fleet to control operations in the area controlled by Southern Command, which consists of US assets in and around Central and South America.[25]

Shore establishment commands exist to support the mission of the seaborne fleets through the use of facilities on land. Focusing on logistics and combat-readiness, they are essential for the smooth, continuous and complete operation of naval forces. The variety of commands reflect the complexity of the modern US Navy and range from naval intelligence to personnel training to maintaining repair facilities. Two of the major logistics and repair commands are Naval Sea Systems Command and Naval Air Systems Command. Other commands such as the Office of Naval Intelligence, the United States Naval Observatory, and the Naval War College focus on intelligence and strategy. Training commands include the Naval Strike and Air Warfare Center and the United States Naval Academy.
The Navy maintains several "Naval Forces Commands" which operate naval shore facilities and serve as liaison units to local ground forces of the Air Force and Army. Such commands are answerable to a Fleet Commander as the shore protector component of the afloat command. During times of war, all Naval Forces Commands augment to become task forces of a primary fleet. Some of the larger Naval Forces Commands in the Pacific Ocean include Commander Naval Forces Korea (CNFK), Commander Naval Forces Marianas (CNFM), and Commander Naval Forces Japan (CNFJ).

Because of the lack of full scale amphibious operations in recent conflicts, there has been pressure to cut the "gator navy" below the two regiments requirement of the Marines.[30] This is a reduction from the programmatic goal of 2.5 Marine Expeditionary Brigades and actual structure of 2.07 MEB equivalents in 1999.[31]

A "shooter" in working uniform gives the signal to launch an F/A-18 Super Hornet from the USS Enterprise (CVN-65).
Sailors prove they have mastered skills and deserve responsibilities by completing Personnel Qualification Standards (PQS) tasks and examinations. Among the most important is the "warfare qualification", which denotes a journeyman level of capability in Surface Warfare, Aviation Warfare, Naval Aircrew, Special Warfare or Submarine Warfare. Many qualifications are denoted on a sailor's uniform with U.S. Navy badges and insignia.
The Navy's personnel, but not missions, have been cut since the early 2000s, forcing the use of fewer sailors to cover the same jobs and hurting readiness and morale.[33]
Main article: U.S. Navy officer rank insigniaSee also: List of United States Navy staff corps
Commissioned officers in the Navy have pay grades ranging from O-1 to O-10, with O-10 being the highest; those with paygrades between O-1 through O-4 are considered junior officers and O-5 and O-6 as senior officers. Officers in the O-7 to O-10 range are called flag officers or "the admiralty." Promotion through O-8 is based on performance in an officer's current paygrade, which is recorded in "FITREPS" (fitness reports), usually self-written by the officer and edited by superiors. Promotions to Vice Admiral (O-9) and Admiral (O-10) are based on assignment to specific positions and subject to U.S. Senate confirmation. Above the rank of Admiral is Fleet Admiral (O-11), which was awarded to only four officers in World War II and is intended to be used only during a declared war. In 1899, a special rank called Admiral of the Navy was created for Admiral George Dewey, a war hero of the Spanish-American War, with the condition that it would cease to exist upon his death.[34][35] Commissioned officers originate from the United States Naval Academy, Naval Reserve Officer Training Corps (NROTC), Officer Candidate School (OCS), and a host of other commissioning programs such as the Seaman to Admiral-21 program, the Limited Duty Officer and Chief Warrant Officer Selection Programs, the United States Merchant Marine Academy, or receive direct commissions via Officer Development School (ODS) or from its reserve component, the Direct Commission Officer School (DCO School).

Enlisted members of the Navy have pay grades from E-1 to E-9, with E-9 being the highest. All enlisted sailors with paygrades of E-4 and higher are considered Petty Officers while those at E-7 and higher are further named Chief Petty Officers. Those who demonstrate superior performance are given an increase in paygrade; the official Navy term is to be advanced. Two notable advancements are from Seaman to Petty Officer Third Class (E-3 to E-4) and from Petty Officer First Class to Chief Petty Officer (E-6 to E-7). Advancement to Chief Petty Officer is especially significant and is marked by a special induction ceremony.
Enlisted members of pay grades E-4 and above are said to be "rated," meaning that they possess a rating, or occupational specialty. Members of grades E-1 to E-3 can become "strikers," meaning they have rating designations like Petty Officer (example: a BM3 is a Petty Officer Third Class rated as a Boatswain's Mate; BMSN is a Seaman designated as a Boatswain's Mate striker), but the striker is doing on the job training to become a rated petty officer rather than attending a school to become rated. Whether a designated striker or not, personnel in the pay grades of E-3 and below are all considered "Non-Rates." There are more than 50 ratings covering a broad range of skills and subspecialties.
For example, SA SMITH, MARY, would be considered a Seaman Apprentice. Prior to her rank of SA a rating would be placed. Therefore, her entire title would be ITSA SMITH, MARY. IT indicating that she is training to become an Information Systems Technician. As for ENFN THOMPSON, JOHN. EN specifying that he is training as Engineman and FN as Fireman.

[edit] Uniforms and appearance
A Vice Admiral returns salute from enlisted sailors in dress uniform at a ceremony.Main article: Uniforms of the United States Navy
The uniforms of the United States Navy are designed "to combine professionalism and naval heritage with versatility, safety, and comfort".[38] The Navy currently incorporates many different styles that are specific for a variety of uses and occasions. In most cases, distinctions are made to distinguish officers and enlisted men in their uniformed appearance. U.S. Navy uniforms can generally be divided into three categories: dress uniforms, service uniforms, and working uniforms.
* Dress uniforms are worn during military-related formal occasions, such as ceremonies and other official functions. Many types of dress uniforms are used in the Navy with the full range of formal requirements represented. Service dress is the least formal dress uniform, full dress is one step higher in formality, and mess dress is the most formal dress available.
* Service uniforms are designed for daily wear and are most often worn in office or classroom-type settings, as well as other occasions in which physical activity is at a minimum.[39] The most visible distinction between officers and enlisted personnel are the color of the service uniform. Only officers and chief petty officers are authorized to wear Service Khaki; all other personnel must wear one of the Winter Blue or Summer White (depending on the season), or the Navy Service Uniform (which will eventually replace Winter Blue and Summer White).[40]
Recently, the Navy completed a project named "Task Force Uniform" to streamline Navy uniforms. Among the changes are that enlisted personnel from Seaman Recruit to Petty Officer First Class (E1-E6) will have one year-round service uniform instead of winter blues and summer whites. All personnel from Seaman Recruit to Admiral will also have new working uniforms dubbed Navy Working Uniform (NWU) to replace the wash khakis, coveralls, dungarees, and aviation working greens currently in use. The uniform is a digital patterned camouflage in predominantly haze gray and blue hues.[41]
Grooming for both male and female sailors is regulated to a high degree, with exact standards in regards to hair, facial hair, use of cosmetics, and jewelry. New male recruits are given the military crew cut and are prohibited from having hair longer than four inches (102 mm) while in the service. Men are required to be clean shaven at all times, although mustaches are allowed. Women do not have a hair length regulation, however hair cannot fall past the bottom edge of the uniform collar and the style of hair is strictly controlled. Multicolored hair, body piercing, and tattoos on the head, neck, and hands are banned for both sexes.[42]
Main article: List of United States Navy installations Map of Navy bases in the United States.
The size, complexity, and international presence of the United States Navy require a large number of navy installations to support its operations. While the majority of bases are located inside the United States itself, the Navy maintains a significant number of facilities abroad, either in U.S.-controlled territories or in foreign countries under a Status of Forces Agreement (SOFA).
[edit] Western United States and Hawaii
The Navy's largest complex is China Lake, California, which covers 1.1 million acres (4500 km ) of land, or approximately 1/3 of the United States Navy's total land holdings.[43]
Naval Base San Diego, California is principal home to the Pacific Fleet (although the headquarters is located in Pearl Harbor). NAS North Island is located on the north side of Coronado, and is home to Headquarters for Naval Air Forces and Naval Air Force Pacific, the bulk of the Pacific Fleet's helicopter squadrons, and part of the West Coast aircraft carrier fleet. The Naval Special Warfare Center is the primary training center for SEALs, and is also located on Coronado. The other major collection of naval bases on the west coast is in Puget Sound, Washington. Among them, Naval Station Everett is one of the newer bases and the Navy states that it is its most modern facility.[44] NAS Fallon, Nevada serves as the primary training ground for Navy Strike aircrews, and is home to the Naval Strike Air Warfare Center. Master Jet Bases are also located at NAS Lemoore, California and NAS Whidbey Island, Washington, while the carrier-based airborne early warning aircraft community and major air test activities are located at NAS Point Mugu, California. The naval presence in Hawaii is centered on Pearl Harbor Naval Base, which hosts the headquarters of the Pacific Fleet and many of its subordinate commands.[43]
[edit] United States territories
Guam, an island strategically located in the Western Pacific Ocean, maintains a sizable U.S. Navy presence, including Naval Base Guam. The westernmost U.S. territory, it contains a natural deep water harbor capable of harboring even aircraft carriers in emergencies.[45] Its naval air station was deactivated[46] in 1995 and its flight activities transferred to nearby Andersen Air Force Base. Puerto Rico in the Caribbean formerly housed Roosevelt Roads Naval Station, which was shut down in 2004 shortly after the controversial closure of the live ordnance training area on nearby Vieques Island.[43]
The largest overseas base is in Yokosuka, Japan,[47] which serves as the homeport for the Navy's largest forward-deployed fleet and is a significant base of operations in the Western Pacific. European operations revolve around facilities in Italy (Sigonella and Naples), Spain and Greece with Naples as the homeport for the Sixth Fleet and CNRE Command Naval Region Europe, which are based in Gaeta. In the Middle East, naval facilities are located almost exclusively in countries bordering the Persian Gulf, with Manama, Bahrain serving as the headquarters of U.S. Naval Forces Central Command and U.S. Fifth Fleet. Guant namo Bay in Cuba is the oldest overseas facility and has become known in recent years as the location of a detention camp for suspected al-Qaeda operatives.[48]

[edit] Historically significant vessels
The U.S. Navy has operated a number of vessels important to both United States and world naval history:
* USS Monitor and CSS Virginia are together known for participating in the first engagement between two steam-powered ironclads, known as the Battle of Hampton Roads. The Monitor was the first ironclad built by the U.S. Navy and its design introduced the rotating gun turret to naval warfare.
* USS Alligator was the first submarine built by the U.S. Navy. The submarine sank in 1863 while being towed during a storm and never saw combat. Though not technically a U.S. Navy vessel, H.L. Hunley (from the same war and era) was the first successful combat submarine.
* USS Maine (ACR-1)In January 1898, the Maine was sent from Key West, Florida, to Havana, Cuba, to protect U.S. interests during a time of local insurrection and civil disturbances. Three weeks later, on February 15 at 9:40 p.m., an explosion on board the Maine occurred in the Havana Harbor. The explosion was a precipitating cause of the Spanish-American War that began in April 1898.
* USS George Washington (SSBN-598), commissioned in 1959, first ever ballistic missile submarine.
* USS Enterprise (CVN-65) was the world's first nuclear-powered aircraft carrier when she was commissioned in 1961.

Main article: List of United States Navy weapons
Aviation Ordnancemen loading GBU-12 bombs.
Naval fixed-wing aircraft employ much of the same weapons as the United States Air Force for both air-to-air and air-to-surface combat. Air engagements are handled by the heat-seeking Sidewinder and the radar guided AMRAAM missiles along with the M61 Vulcan cannon for close range dogfighting. For surface strikes, Navy aircraft utilize a combination of missiles, smart bombs, and dumb bombs. On the list of available missiles are the Maverick, SLAM-ER and JSOW. Smart bombs include the GPS-guided JDAM and the laser-guided Paveway series. Unguided munitions such as dumb bombs and cluster bombs make up the rest of the weapons deployed by fixed-wing aircraft.
Rotary aircraft weapons are focused on anti-submarine warfare (ASW) and light to medium surface engagements. To combat submarines, helicopters use Mark 46 and Mark 50 torpedoes. Against small watercraft, they utilize Hellfire and Penguin air to surface missiles. Helicopters also employ various types of mounted anti-personnel machine guns, including the M60, M240, GAU-16/A, and GAU-17/A.
Nuclear weapons in the U.S. Navy arsenal are deployed through ballistic missile submarines and aircraft. The Ohio-class submarine carries the latest iteration of the Trident missile, a three stage, underwater launched, nuclear ICBM with MIRV capability; the current Trident II (D5) version is expected to be in service past 2020.[66] The Navy s other nuclear weapon is the air-deployed B61 nuclear bomb. The B61 is a thermonuclear device that can be dropped by strike aircraft such as the F/A-18 Hornet and Super Hornet at high speed from a large range of altitudes. It can be released through free-fall or parachute and can be set to detonate in the air or on the ground.
The major players in U.S. Navy special operations are the United States Navy SEALs and the Special Warfare Combatant-craft Crewmen (SWCCs, pronounced "swicks").
The SEALs derive their name from the environments in and from which they can operate: SEa, Air, and Land. Their distinguishing specialty, however, is maritime operations striking from and returning to the sea.[67] The SEALs are a flexible group of naval special operations forces who are trained to conduct clandestine warfare, most often in small-unit actions.
* Naval Special Warfare Group ONE and Group TWO each consist of four teams of Navy SEALs and a few Naval Special Warfare (NSW) Units. NSW units are charged with overall command and control and planning of special operations within their geographic jurisdiction.
* Group THREE is made up of SEAL Delivery Vehicle (SDV) Teams. SEALs who are assigned to SDV teams specialize in the use of Swimmer Delivery Vehicles (known as "SEAL Delivery Vehicles" in American service) and Advanced SEAL Delivery Systems (ASDSs). These watercraft are submersibles that are designed to insert SEAL operators underwater, from long distances offshore.
* Group FOUR comprises all of the Navy's Special Boat Teams.
* The U.S. Naval Special Warfare Development Group, also known as Dev Group or DEVGRU, is the United States military's premier Maritime Counter-Terrorism unit. While the Navy confirms the existence of the unit, it merely states that the role of Dev Group is to test, evaluate, and develop technology and maritime, ground and airborne tactics for Navy Special Warfare; no official mention of counter-terrorism concerning DEVGRU is made. Though much of the information regarding this unit is classified, it is estimated that the group consists of approximately 200 active operators.[69]
* The Operational Support Group is the reserve element of NSWC, providing support to active units when necessary.[70]
* The Naval Special Warfare Center, located in Coronado, California, is the main training center for Navy special operations personnel including the United States Navy SEALs.
Although not under the jurisdiction of NSW Command, Navy Explosive Ordnance Disposal Units often work closely with special operations teams. Trained to be combat-ready and highly mobile, EOD units are entrusted with nullifying hazardous ordnance in a number of different maritime environments.[71] They are also able to conduct underwater anti-mine operations using marine mammals.[72]
[edit] Naval Expeditionary Combat Command
Navy Expeditionary Combat Command (NECC), established in January 2006, serves as the single functional command for the Navy's expeditionary forces and as central management for the readiness, resources, manning, training and equipping of those forces.

NECC consolidates, aligns and integrates diverse expeditionary capabilities and combat support elements to create consistent expeditionary practices, procedures, requirements and logistics in the battle space. NECC s enterprise approach will yield improved efficiencies and effectiveness through economies of scale and common processes.
NECC is a command element and force provider for integrated maritime expeditionary missions. NECC is a core expeditionary force providing effective waterborne and ashore anti-terrorism, force protection, theater security cooperation and engagement, and humanitarian assistance/disaster relief contingencies. Upon request, NECC supplements Coast Guard homeland security requirements while training and equipping forces to support mission requirements.
NECC capabilities include; Explosive Ordnance Disposal, Maritime Expeditionary Security, Riverine, Diving Operations, Naval Construction, Maritime Civil Affairs, Expeditionary Training, Expeditionary Logistics, Expeditionary Intelligence, Combat Camera, Expeditionary Combat Readiness, and Maritime Expeditionary Security.
The Maritime Expeditionary Security Force s (MESF) (formerly known as Naval Coastal Warfare) primary mission is force protection conducted through fleet support with operations around the world. Anti-Terrorism and Force Protection missions include harbor and homeland defense, coastal surveillance, and special missions. Specialized units work together with MESF squadron staffs providing intelligence and communications. MESF units deploy worldwide to detect, deter, and defend an area, unit, or High Value Asset. Recent locations include the United States, Korea, Saudi Arabia, Kuwait, Bahrain, United Arab Emirates, and Egypt.

A number of presidents served in the Navy before their political careers, including John F. Kennedy (who commanded the famous PT-109), Lyndon B. Johnson, Richard Nixon, Gerald Ford, Jimmy Carter, and George H.W. Bush. Both Theodore Roosevelt and Franklin D. Roosevelt were the Assistant Secretary of the Navy prior to their presidencies. Many members of Congress served in the Navy, notably U.S. Senators John McCain and John Kerry. Other notable former members of the U.S. Navy include astronauts, entertainers, authors, and professional athletes such as David Robinson, and Roger Staubach.
