2546-574: Is carbon steel , typically consisting of hot-rolled round bars with deformation patterns embossed into its surface. Steel and concrete have similar coefficients of thermal expansion , so a concrete structural member reinforced with steel will experience minimal differential stress as the temperature changes. Other readily available types of rebar are manufactured of stainless steel , and composite bars made of glass fiber , carbon fiber , or basalt fiber . The carbon steel reinforcing bars may also be coated in zinc or an epoxy resin designed to resist

2680-709: Is a distinct, separate service branch with its own uniformed service chief – the Commandant of the Marine Corps, a four-star general. The Marine Corps depends on the Navy for medical support (dentists, doctors , nurses, medical technicians known as corpsmen ) and religious support (chaplains). Thus, Navy officers and enlisted sailors fulfill these roles. When attached to Marine Corps units deployed to an operational environment they generally wear Marine camouflage uniforms, but otherwise, they wear Navy dress uniforms unless they opt to conform to Marine Corps grooming standards. In

2814-424: Is also used in high-corrosion environments. It is available in many forms, such as spirals for reinforcing columns, common rods, and meshes. Most commercially available rebar is made from unidirectional fibers set in a thermoset polymer resin and is often referred to as FRP.

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 guns and manned them in

9782-424: The circumference of each of the future upper dome bases. They then scoped out the area of the domes and proceeded to construct the steel framing , steel liner and rebar . Workers continuously poured concrete that ranged in thickness from two feet at the crown to eight feet at the base. Once the concrete cured, it was pre-stressed by pressure grouting the area between the concrete and the basalt. Upon completion of

9916-472: The city of Honolulu. While all test results for contamination at the Navy drinking water shaft have come back well within safe drinking water standards and results from the Halawa shaft have shown no jet fuel related contaminants, the Navy, the Environmental Protection Agency, and the Hawaii Department of Health conducted studies to evaluate groundwater conditions and any potential impacts to groundwater resources in

10050-461: The concrete by filling void space between the concrete and the gunite . When finished, the tanks were tested by slowly filling them with water while laborers in boats inspected the entire surface area of the steel liner. The Japanese attack on Pearl Harbor took place during the construction of Red Hill, and eight construction workers were killed by strafing aircraft. A portion of the site was used to bury hundreds of bodies of Navy personnel killed in

10184-406: The concrete, it can still be pulled out of the concrete under high stresses, an occurrence that often accompanies a larger-scale collapse of the structure. To prevent such a failure, rebar is either deeply embedded into adjacent structural members (40–60 times the diameter), or bent and hooked at the ends to lock it around the concrete and other rebar. This first approach increases the friction locking

10318-411: The current U.S. Navy remains an asset for the United States. Moreover, it is the principal means through which the U.S. maintains international global order, namely by safeguarding global trade and protecting allied nations. 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

10452-655: The effects of corrosion, especially when used in saltwater environments. Bamboo has been shown to be a viable alternative to reinforcing steel in concrete construction. These alternative types tend to be more expensive or may have lesser mechanical properties and are thus more often used in specialty construction where their physical characteristics fulfill a specific performance requirement that carbon steel does not provide. Reinforcing bars in masonry construction have been used since antiquity , with Rome using iron or wooden rods in arch construction. Iron tie rods and anchor plates were later employed across Medieval Europe, as

10586-515: The end of the war. The U.S. Navy had followed in the footsteps of the navies of Great Britain and Germany which favored concentrated groups of battleships as their main offensive naval weapons. The development of the aircraft carrier and its devastating use by the Japanese against the U.S. at Pearl Harbor, however, shifted U.S. thinking. The Pearl Harbor attack destroyed or took out of action a significant number of U.S. Navy battleships. This placed much of

10720-488: The excavation, workers erected a steel tower in the center to the full height of 250 feet. The tower served to support concrete chutes, pipes, booms, and other equipment necessary to install the piping, concrete, and steel linings. Workers then began to erect the steel liner and rebar incrementally so that they could pour concrete in stages. Concrete was poured continually and workers had to remove wooden shoring as concrete filled. They injected pressurized grout to pre-stress

10854-532: The extent of contamination in the ground around Red Hill. Each technique will be evaluated in terms of feasibility of implementation and effectiveness in detecting light non-aqueous phase liquid, which refers to fuel floating on top of the groundwater. The Navy will also investigate a number of remediation methods for use in the Red Hill area. The Navy will evaluate methods based on their feasibility of implementation, suitableness for use in fractured basalt geology, and effectiveness in reducing contamination. In May 2016

10988-514: The face of the expiration of budget relief offered by the Bipartisan Budget Act of 2013 and CNO Jonathan Greenert said that a ten ship carrier fleet would not be able to sustainably support military requirements. The British First Sea Lord George Zambellas said that the USN had switched from "outcome-led to resource-led" planning. One significant change in U.S. policymaking that is having

11122-580: The first three commands being led by four-star admirals. The United States First Fleet existed after World War II from 1947, but it was redesignated the Third Fleet in early 1973. The Second Fleet was deactivated in September 2011 but reestablished in August 2018 amid heightened tensions with Russia. It is headquartered in Norfolk, Virginia, with responsibility over the East Coast and North Atlantic. In early 2008,

11256-551: The first three were brought into service: USS  United States , USS  Constellation , and USS  Constitution . Due to his strong posture on having a strong standing Navy during this period, John Adams is "often called the father of the American Navy". In 1798–99 the Navy was involved in an undeclared Quasi-War with France. From 1801 to 1805, in the First Barbary War , the U.S. Navy defended U.S. ships from

11390-424: The first time at the Battle of Hampton Roads in 1862, which pitted USS  Monitor against CSS  Virginia . For two decades after the war, however, the U.S. Navy's fleet was neglected and became technologically obsolete . A modernization program beginning in the 1880s when the first steel-hulled warships stimulated the American steel industry, and "the new steel navy" was born. This rapid expansion of

11524-484: The first uniform regulations for officers were issued in 1802 on the formation of the Navy Department. The predominant colors of U.S. Navy uniforms are navy blue and white. U.S. Navy uniforms were based on Royal Navy uniforms of the time and have tended to follow that template. Navy officers serve either as a line officer or as a staff corps officer . Line officers wear an embroidered gold star above their rank of

11658-452: The fleet has shrunk and that in the face of declining budgets in the future, the U.S. Navy must rely even more on international partnerships. In its 2013 budget request, the navy focused on retaining all eleven big deck carriers, at the expense of cutting numbers of smaller ships and delaying the SSBN replacement. By the next year the USN found itself unable to maintain eleven aircraft carriers in

11792-681: The fleet, and making naval technological improvements. During the Mexican–American War the U.S. Navy blockaded Mexican ports, capturing or burning the Mexican fleet in the Gulf of California and capturing all major cities in Baja California peninsula. In 1846–1848 the Navy successfully used the Pacific Squadron under Commodore Robert F. Stockton and its marines and blue-jackets to facilitate

11926-462: The fuel level in each tank to one sixteenth of an inch and controls the movement of fuel throughout the facility. If a tank level decreases by as little as half an inch, alarms will sound in Red Hill's control room, which is continuously staffed. Many entities, including the U.S. Navy , University of Hawaii , and U.S. Geological Survey , study the movement of groundwater in and around Red Hill. Navy modeling to date indicates any fuel constituents in

12060-428: The groundwater contamination since the late 1990s — and generated thousands of pages of reports on the topic — officials from Honolulu's Board of Water Supply say they were never informed about the problems until after this most recent spill. The Honolulu Board of Water Supply is responsible for purveying the county's drinking water. "I'm very concerned about the situation," said Ernest Lau, manager and chief engineer for

12194-572: The hands of the Barbary pirates from Algiers , the United States Congress passed the Naval Act of 1794 for the construction of six heavy frigates , the first ships of the Navy. The United States Navy played a major role in the American Civil War by blockading the Confederacy and seizing control of its rivers. It played the central role in the World War II defeat of Imperial Japan . The United States Navy emerged from World War II as

12328-405: The idea that Kahn's reinforcing system in concrete beams would act as a Warren truss and also noted that this system would not provide the adequate amount of shear stress reinforcement at the ends of the simply supported beams, the place where the shear stress is greatest. Furthermore, Turner warned that Kahn's system could result in a brittle failure as it did not have longitudinal reinforcement in

12462-929: The industry manufactured them to provide the cross-sectional area equivalent of standard square bar sizes that were formerly used. The diameter of the equivalent large format round shape is rounded to the nearest 1 ⁄ 8 inch to provide the bar size. For example, #9 bar has a cross section of 1.00 square inch (6.5 cm ), and therefore a diameter of 1.128 inches (28.7 mm). #10, #11, #14, and #18 sizes correspond to 1 1 ⁄ 8 inch, 1 1 ⁄ 4 , 1 1 ⁄ 2 , and 2-inch square bars, respectively. Sizes smaller than #3 are no longer recognized as standard sizes. These are most commonly manufactured as plain round undeformed rod steel but can be made with deformations. Sizes smaller than #3 are typically referred to as "wire" products and not "bar" and specified by either their nominal diameter or wire gage number. #2 bars are often informally called "pencil rod" as they are about

12596-682: The local guard. As rust takes up greater volume than the steel from which it was formed, it causes severe internal pressure on the surrounding concrete, leading to cracking, spalling , and, ultimately, structural failure . This phenomenon is known as oxide jacking . This is a particular problem where the concrete is exposed to salt water, as in bridges where salt is applied to roadways in winter, or in marine applications. Uncoated, corrosion-resistant low- carbon / chromium (microcomposite), silicon bronze , epoxy -coated, galvanized , or stainless steel rebars may be employed in these situations at greater initial expense, but significantly lower expense over

12730-468: The mission of the U.S. Armed Forces is "to be prepared to conduct prompt and sustained combat operations in support of the national interest." The Navy's five enduring functions are: sea control , power projection , deterrence , maritime security , and sealift . It follows then as certain as that night succeeds the day, that without a decisive naval force we can do nothing definitive, and with it, everything honorable and glorious. Would to Heaven we had

12864-529: The most common ground since aircrews are guided in their use of aircraft by standard procedures outlined in a series of publications known as NATOPS manuals. The United States Coast Guard , in its peacetime role with the Department of Homeland Security , fulfills its law enforcement and rescue role in the maritime environment. It provides Law Enforcement Detachments (LEDETs) to Navy vessels, where they perform arrests and other law enforcement duties during naval boarding and interdiction missions. In times of war,

12998-469: The most important is the "warfare qualification", which denotes a journeyman level of capability in Surface Warfare, Aviation Warfare, Information Dominance Warfare, Naval Aircrew, Special Warfare, Seabee Warfare, Submarine Warfare or Expeditionary Warfare. Many qualifications are denoted on a sailor's uniform with U.S. Navy badges and insignia . The uniforms of the U.S. Navy have evolved gradually since

13132-577: The most powerful navy in the world. The modern United States Navy maintains a sizable global presence, deploying in strength in such areas as the Western Pacific , the Mediterranean , and the Indian Ocean. It is a blue-water navy with the ability to project force onto the littoral regions of the world, engage in forward deployments during peacetime and rapidly respond to regional crises, making it

13266-495: The naval service dress uniform while staff corps officers and commissioned warrant officers wear unique designator insignias that denotes their occupational specialty. Warrant and chief warrant officer ranks are held by technical specialists who direct specific activities essential to the proper operation of the ship, which also require commissioned officer authority. Navy warrant officers serve in 30 specialties covering five categories. Warrant officers should not be confused with

13400-446: The nominal bar diameter in millimeters, as an "alternate size" specification. Substituting a true metric size for a US/Imperial size is called a hard conversion , and sometimes results in the use of a physically different sized bar. bar size size (soft) Metric bar designations represent the nominal bar diameter in millimeters, rounded to the nearest 5 mm. bar size (kg/m) (mm) Area (mm ) Metric bar designations represent

13534-508: The nominal bar diameter in millimetres. Preferred bar sizes in Europe are specified to comply with Table 6 of the standard EN 10080 , although various national standards still remain in force (e.g. BS 4449 in the United Kingdom). In Switzerland some sizes are different from European standard. bar size density (kg/m) diameter (mm) area (mm ) Reinforcement for use in concrete construction

13668-691: 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 Sea Power Symposium in Newport, Rhode Island on 17 October 2007. 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

13802-410: The number two official in the Navy Department during World War I, appreciated the Navy and gave it strong support. In return, senior leaders were eager for innovation and experimented with new technologies, such as magnetic torpedoes, and developed a strategy called War Plan Orange for victory in the Pacific in a hypothetical war with Japan that would eventually become reality. The U.S. Navy grew into

13936-761: The numbers were small enough that the testing facility had to estimate the amount because the numbers were so low. The 17 parts per billion is below the threshold of something we should be concerned about, which is 100 parts per billion." On November 20, 2021, another jet fuel leak at the Red Hill Bulk Fuel Storage Facility contaminated the Joint Base Pearl Harbor–Hickam water system, which supplies about 10,000 civilian and military households and schools. In December 2021, more than 1,000 military families stationed in Hawaii had been forced from their homes after apparent jet fuel contamination in

14070-525: The ocean-going schooner USS Hannah to interdict British merchantmen and reported the captures to the Congress. On 13 October 1775, the Continental Congress authorized the purchase of two vessels to be armed for a cruise against British merchantmen; this resolution created the Continental Navy and is considered the first establishment of the U.S. Navy. The Continental Navy achieved mixed results; it

14204-427: The operational environment, as an expeditionary force specializing in amphibious operations, Marines often embark on Navy ships to conduct operations from beyond territorial waters. Marine units deploying as part of a Marine Air-Ground Task Force (MAGTF) operate under the command of the existing Marine chain of command. Although Marine units routinely operate from amphibious assault ships, the relationship has evolved over

14338-447: The other organizations, playing a coordinating role. In 1834, the United States Marine Corps came under the Department of the Navy. Historically, the Navy has had a unique relationship with the USMC, partly because they both specialize in seaborne operations. Together the Navy and Marine Corps form the Department of the Navy and report to the Secretary of the Navy. However, the Marine Corps

14472-537: The people of Hawaii, the environment, and our nation." The commander of the Joint Task Force is Vice. Adm. John F.G. Wade . Red Hill is located under a volcanic mountain ridge near Honolulu . It was declared a Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1995. Before the United States entered World War II , the Roosevelt Administration became concerned about

14606-510: The qualification of “tentative” was removed when the updated standard ASTM A305-49 was issued in 1949. The requirements for deformations found in current specifications for steel bar reinforcing, such as ASTM A615 and ASTM A706, among others, are the same as those specified in ASTM A305-49. Concrete is a material that is very strong in compression , but relatively weak in tension . To compensate for this imbalance in concrete's behavior, rebar

14740-491: The same size as a pencil. When US/Imperial sized rebar are used in projects with metric units, the equivalent metric size is typically specified as the nominal diameter rounded to the nearest millimeter. These are not considered standard metric sizes, and thus is often referred to as a soft conversion or the "soft metric" size. The US/Imperial bar size system recognizes the use of true metric bar sizes (No. 10, 12, 16, 20, 25, 28, 32, 36, 40, 50 and 60 specifically) which indicates

14874-635: The senior command meant that naval forces were not contributed until late 1917. Battleship Division Nine was dispatched to Britain and served as the Sixth Battle Squadron of the British Grand Fleet. Its presence allowed the British to decommission some older ships and reuse the crews on smaller vessels. Destroyers and U.S. Naval Air Force units like the Northern Bombing Group contributed to the anti-submarine operations. The strength of

15008-413: The service life of the project. Extra care is taken during the transport, fabrication, handling, installation, and concrete placement process when working with epoxy-coated rebar, because damage will reduce the long-term corrosion resistance of these bars. Even damaged epoxy-coated bars have shown better performance than uncoated reinforcing bars, though issues from debonding of the epoxy coating from

15142-962: The shore establishment, as of April 2011 , are the Naval Education and Training Command , the Navy Installations Command , the Naval Meteorology and Oceanography Command , the Naval Information Warfare Systems Command , the Naval Facilities Engineering Command , the Naval Supply Systems Command , the Naval Air Systems Command , the Naval Sea Systems Command , the Bureau of Medicine and Surgery ,

15276-564: The side in favor of the concrete reinforcing systems seen today. Requirements for deformations on steel bar reinforcement were not standardized in US construction until about 1950. Modern requirements for deformations were established in "Tentative Specifications for the Deformations of Deformed Steel Bars for Concrete Reinforcement", ASTM A305-47T. Subsequently, changes were made that increased rib height and reduced rib spacing for certain bar sizes, and

15410-533: The steel tie bars that constrain and reinforce the masonry of Nevyansk Tower or ancient structures in Rome and the Vatican. Steel has a thermal expansion coefficient nearly equal to that of modern concrete . If this were not so, it would cause problems through additional longitudinal and perpendicular stresses at temperatures different from the temperature of the setting. Although rebar has ribs that bind it mechanically to

15544-571: The successful bombardment and capture of the city. This successful landing and capture of Veracruz opened the way for the capture of Mexico City and the end of the war. The U.S. Navy established itself as a player in United States foreign policy through the actions of Commodore Matthew C. Perry in Japan, which resulted in the Convention of Kanagawa in 1854. Naval power played a significant role during

15678-471: The tank with jet fuel (JP-8). During this process, the inventory management alarms sounded. Red Hill operators first assumed the alarm system was malfunctioning or producing false positives because the tank was recently overhauled and should not have been leaking. Eventually, the U.S. Navy determined the alarms were not false and reported a 27,000 gallon jet fuel loss to the Hawaii Department of Health and

15812-548: The tower was connected to its cast iron tented roof , crowned with one of the first known lightning rods . However, not until the mid-19th century, with the embedding of steel bars into concrete (thus producing modern reinforced concrete ), did rebar display its greatest strengths. Several people in Europe and North America developed reinforced concrete in the 1850s. These include Joseph-Louis Lambot of France, who built reinforced concrete boats in Paris (1854) and Thaddeus Hyatt of

15946-477: The treaty. The New Deal used Public Works Administration funds to build warships, such as USS  Yorktown  (CV-5) and USS  Enterprise  (CV-6) . By 1936, with the completion of USS  Wasp  (CV-7) , the U.S. Navy possessed a carrier fleet of 165,000 tonnes displacement , although this figure was nominally recorded as 135,000 tonnes to comply with treaty limitations. Franklin Roosevelt ,

16080-649: The twisting would weaken the iron. In 1889, Ransome worked on the West Coast mainly designing bridges. One of these, the Alvord Lake Bridge in San Francisco's Golden Gate Park, was the first reinforced concrete bridge built in the United States. He used twisted rebar in this structure. At the same time Ransome was inventing twisted steel rebar, C.A.P. Turner was designing his "mushroom system" of reinforced concrete floor slabs with smooth round rods and Julius Kahn

16214-449: The vertical shafts for all 20 tanks concurrently with mining of the upper access and lower access tunnels. The tunnels were aligned directly in the middle of the parallel rows of shafts. Once perpendicular to the shafts, cross tunnels were mined to connect the shafts to the main access tunnels. For constructability and safety reasons ( cave-ins ), the upper domes needed to be built first, so the miners excavated individual ring tunnels around

16348-499: The vulnerability of the many above-ground fuel storage tanks at Pearl Harbor. In 1940 it decided to build a new underground facility that would store more fuel and be safe from an enemy aerial attack. The Red Hill site would provide unprecedented flow rates of fuel due to its elevation. In addition, the site's unique geological characteristics, including basalt rock, could support such large tanks. Federal, local government and contracted engineers and geologists performed many surveys of

16482-524: The water supply at Joint Base Pearl Harbor–Hickam . About 2,700 homes in 10 communities were in the affected area. Residents had complained about foul-smelling tap water bearing an oily sheen, as well as symptoms such as nausea, diarrhea and intense headaches. Secretary of the Navy Carlos Del Toro told residents, “I deeply apologize to each and every one of you and to the people of Hawaii that this incident may have been destructive to your lives." It

16616-586: The years much as the Commander of the Carrier Air Group/Wing (CAG) does not work for the carrier commanding officer, but coordinates with the ship's CO and staff. Some Marine aviation squadrons, usually fixed-wing assigned to carrier air wings train and operate alongside Navy squadrons; they fly similar missions and often fly sorties together under the cognizance of the CAG. Aviation is where the Navy and Marines share

16750-569: Was a major participant in the Korean and Vietnam Wars , 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 U.S. Navy conducted various combat operations in the Persian Gulf against Iran in 1987 and 1988, most notably Operation Praying Mantis . The Navy

16884-653: Was conditionally approved by the regulatory agencies on December 2, 2016, subject to changes as detailed in the conditional approval letter (letter is available for viewing below). On January 5, 2017, the Navy submitted a new version of the Section 6 & 7 Scope of Work, available below, that addressed all of the issues noted in the Conditional Approval letter. In 2020, the Honolulu Civil Beat reported that even though Navy and state health officials have known about

17018-560: Was experimenting with an innovative rolled diamond-shaped rebar with flat-plate flanges angled upwards at 45° (patented in 1902). Kahn predicted concrete beams with this reinforcing system would bend like a Warren truss , and also thought of this rebar as shear reinforcement. Kahn's reinforcing system was built in concrete beams, joists, and columns. The system was both praised and criticized by Kahn's engineering contemporaries: Turner voiced strong objections to this system as it could cause catastrophic failure to concrete structures. He rejected

17152-484: 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 . The U.S. Navy has also been involved in search and rescue/search and salvage operations, sometimes in conjunction with vessels of other countries as well as with U.S. Coast Guard ships. Two examples are

17286-681: Was faced with a two-front war on the seas. It achieved notable acclaim in the Pacific Theater , where it was instrumental to the Allies' successful " island hopping " campaign. The U.S. Navy participated in many significant battles, including the Battle of the Coral Sea , the Battle of Midway , the Solomon Islands Campaign , the Battle of the Philippine Sea , the Battle of Leyte Gulf , and

17420-691: Was not until 1921 US naval aviation truly commenced. During World War I , the U.S. Navy spent much of its resources protecting and shipping hundreds of thousands of soldiers and marines of the American Expeditionary Force and war supplies across the Atlantic in U-boat infested waters with the Cruiser and Transport Force . It also concentrated on laying the North Sea Mine Barrage . Hesitation by

17554-477: Was not until May 2022, that the CDC published a study of self-reported symptoms which lasted more than a month. Creation of Joint Task Force Red Hill On September 30, 2022, Joint Task Force Red Hill was officially stood up for the purpose of safely and expeditiously defueling the facility through coordination with State and Federal stakeholders in order to set conditions for closure while continuing to rebuild trust with

17688-440: Was possible because a vertical shaft drilled through the centerline of the tank would allow excavated rock to funnel down onto a series of conveyor belts in the lower access tunnel. Planners and engineers began the process by acquiring the real estate, staging equipment and materials, and building a work camp. The 3,900 workers worked around the clock, seven days a week, to complete the project. Construction started by excavating

17822-408: Was scheduled to come on line by the end of April 2017. Commander Navy Region Hawaii and Naval Surface Group Middle Pacific, Admiral Fuller noted, "there are have been detects of trace amounts of fuel constituents near the Navy drinking water shaft." This is in the groundwater, not the drinking water. "We're talking 17 parts per billion, as opposed to zero. The misperception is that there's a spike, but

17956-463: Was successful in a number of engagements and raided many British merchant vessels, but it lost twenty-four of its vessels and at one point was reduced to two in active service. In August 1785, after the Revolutionary War had drawn to a close, Congress had sold Alliance , the last ship remaining in the Continental Navy due to a lack of funds to maintain the ship or support a navy. In 1972,
