USS Pinnacle (AM-462/MSO-462) was an Aggressive-class minesweeper acquired by the U.S. Navy for the task of removing mines that had been placed in the water to prevent the safe passage of ships.

<i>Aggressive</i>-class minesweeper

The Aggressive-class minesweepers are a class of US-built minesweepers. They are designated as MSO, distinguishing them from the smaller coastal MSCs and inshore MSIs. Besides the US Navy, this class of vessels has also been used by the Belgian Navy and the Norwegian Navy, among others.

Minesweeper Vessel for removing naval mines

A minesweeper is a small naval warship designed to engage in minesweeping. Using various mechanisms intended to counter the threat posed by naval mines, waterways are kept clear for safe shipping.

Pinnacle was laid down 24 August 1953 as AM-462 by Higgins Industries Inc., New Orleans, Louisiana and launched 3 January 1955. She was redesignated as an Ocean Minesweeper, MSO-462, 7 February 1955 and commissioned on 21 October 1955.

Higgins Industries

Higgins Industries was the company owned by Andrew Higgins based in New Orleans, Louisiana, United States. Higgins Industries is most famous for the design and production of the Higgins boat, an amphibious landing craft referred to as LCVP, which was used extensively in the Allied forces' D-Day Invasion of Normandy. Higgins also manufactured PT boats, and produced the first American airborne lifeboat, the model A-1 lifeboat.

North Atlantic operations

Pinnacle was assigned to MinDiv 84 and completed shakedown in Chesapeake Bay and post shakedown overhaul at Charleston, South Carolina, and in June 1956 began preparations for her first deployment to the Mediterranean. Sailing east on 4 September, she visited the United Kingdom and the Netherlands, took part in NATO maneuvers in the North Sea then operated with the U.S. 6th Fleet in the Mediterranean from 20 October to 21 January 1957.

MinDiv was a standard U.S. Navy abbreviation or acronym for "Minesweeper Division."

Shakedown (testing)

A shakedown is a period of testing or a trial journey undergone by a ship, aircraft or other craft and its crew before being declared operational. Statistically, a proportion of the components will fail after a relatively short period of use, and those that survive this period can be expected to last for a much longer, and more importantly, predictable life-span. For example, if a bolt has a hidden flaw introduced during manufacturing, it will not be as reliable as other bolts of the same type.

Chesapeake Bay An estuary in the U.S. states of Maryland and Virginia

The Chesapeake Bay is an estuary in the U.S. states of Maryland and Virginia. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula with its mouth located between Cape Henry and Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others. More than 150 major rivers and streams flow into the Bay's 64,299-square-mile (166,534 km2) drainage basin, which covers parts of six states and all of Washington, D.C.

On 6 February she returned to Charleston, South Carolina, then, through September, furnished services for the Office of Naval Research. Overhaul and local operations followed and in May, 1958, Pinnacle again sailed for the Mediterranean.

Middle East Crisis operations

As tension in the Middle East rose to a new height, Pinnacle steamed directly to the eastern Mediterranean and for most of that deployment cruised off the Levantine states. Between 1 August and 2 October she spent six weeks off Beirut as the 6th Fleet answered Lebanese President Camille Chamoun's request for aid. En route home a series of engineering casualties resulted in the loss of the use of her main engines. Taken in tow by USS Nimble (MSO-459), she arrived at Charleston, South Carolina, 3 November.

1958 Lebanon crisis

The 1958 Lebanon crisis was a Lebanese political crisis caused by political and religious tensions in the country that included a U.S. military intervention. The intervention lasted for around three months until President Camille Chamoun, who had requested the assistance, completed his term as president of Lebanon. American and Lebanese government forces successfully occupied the port and international airport of Beirut. With the crisis over, the United States withdrew.

Levant Geographic and cultural region consisting of the eastern Mediterranean between Anatolia and Egypt

The Levant is an approximate historical geographical term referring to a large area in the Eastern Mediterranean, primarily in Western Asia. In its narrowest sense, it is equivalent to the historical region of Syria. In its widest historical sense, the Levant included all of the eastern Mediterranean with its islands; that is, it included all of the countries along the Eastern Mediterranean shores, extending from Greece to Cyrenaica.

Beirut City in Lebanon

Beirut is the capital and largest city of Lebanon. No recent population census has been conducted, but 2007 estimates ranged from slightly more than 1 million to 2.2 million as part of Greater Beirut. Located on a peninsula at the midpoint of Lebanon's Mediterranean coast, Beirut is the country's largest and main seaport.

Stateside Overhaul

Overhaul, local operations and Caribbean amphibious exercises took up 1959 and in January 1960, Pinnacle deployed to the Mediterranean for another tour with the U.S. 6th Fleet. Returning in June, she resumed a series of local operations Mine Warfare school ship duties and amphibious exercise in the Caribbean. In late January 1962 she steamed to Cape Canaveral, Florida, to act as a back-up ship during the Mercury 6 space shot. In April she reported for duty with the Mine Defense Laboratory, Panama City, Florida, and after upkeep at the end of the summer sailed north to participate in joint U.S.-Canada exercises in the North Atlantic Ocean.

The Caribbean is a region of The Americas that consists of the Caribbean Sea, its islands and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America.

Amphibious warfare Type of offensive military operations

Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, materiel and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs and from mini-submersibles.

United States Sixth Fleet Numbered fleet of the United States Navy

The Sixth Fleet is a numbered fleet of the United States Navy operating as part of United States Naval Forces Europe. The Sixth Fleet is headquartered at Naval Support Activity Naples, Italy. The officially stated mission of the Sixth Fleet in 2011 is that it "conducts the full range of Maritime Operations and Theater Security Cooperation missions, in concert with coalition, joint, interagency, and other parties, in order to advance security and stability in Europe and Africa." The current commander of the Sixth Fleet is Vice Admiral Lisa M. Franchetti.

Continued U.S. 6th Fleet operations

In May 1963, Pinnacle again deployed to the Mediterranean and into 1970 regularly rotated between duty with the 6th Fleet, local operations and training exercises off the east coast, and extended deployment with amphibious forces in the Caribbean. Pinnacle participated in the recovery effort of the Palomares Incident in early 1966. Pinnacle was the first ship to locate the missing hydrogen bomb after making sonar contact. [1]

Deactivation

Pinnacle was struck from the Naval Vessel Register on 1 November 1977; sold for scrapping on 1 May 1978 by the Defense Reutilization and Marketing Service to C. B. Herter of Hopewell, Virginia, for $26,491.
