The Oliver Hazard Perry class is a class of guided-missile frigates named after the U.S. Commodore Oliver Hazard Perry, the hero of the naval Battle of Lake Erie. Also known as the Perry or FFG-7 class, the warships were designed in the United States in the mid-1970s as general-purpose escort vessels inexpensive enough to be bought in large numbers to replace World War II-era destroyers and complement 1960s-era Knox-class frigates.
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition.
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern types of ships below a corvette are coastal patrol craft, missile boat and fast attack craft. In modern terms, a corvette is typically between 500 tons and 2,000 tons, although recent designs may approach 3,000 tons, which might instead be considered a small frigate.
HMAS Geranium was an Arabis-class sloop built in Scotland and launched in 1915. The ship was operated by the Royal Navy as a minesweeper from 1915 until 1919, when she was transferred to the Royal Australian Navy (RAN) for use as a survey ship between 1919 and 1927. The ship was decommissioned in 1927 and scrapped during 1932, with the remains scuttled in 1935.
Two ships of the Royal Navy have borne the name HMS Geranium, after the flower, the geranium:
USS T-3 (SS-61/SF-3) was an AA-1-class submarine in the service of the United States Navy originally named AA-3.
USS Mahan (DD-102) was a Wickes-class destroyer built for the United States Navy. Commissioned in 1918, Mahan was a flush deck destroyer, and the first ship to be named for Rear Admiral Alfred Thayer Mahan. Her main battery consisted of four 4-inch/50 caliber guns.
USS Sinclair (DD-275) was a Clemson-class destroyer in the United States Navy. She was named for Captain Arthur Sinclair.
USS Sharkey (DD-281) was a Clemson-class destroyer in the United States Navy following World War I. She was named for William J. Sharkey.
The Belgian Navy, officially the Belgian Naval Component of the Belgian Armed Forces, is the naval service of Belgium.
The Pondicherry class are a class of minesweepers built for the Indian Navy by the Soviet Union. They are modified versions of the Natya-class minesweeper. The vessels were acquired in two batches. The first were purchased from 1977 to 1980 and the second from 1986 to 1988. Technically, the second batch is referred to as the Karwar class but are physically identical to the first batch with the exception of additional surface-to-air missiles. As minesweepers, they are large and heavily armed. They can serve a dual purpose as an anti-submarine warfare escort. Their hulls are constructed of U3 low magnetic signature steel.
The Petya class was the NATO reporting name for a class of light frigates designed in the 1950s and built for the Soviet Navy in the 1960s. The Soviet designation was "Storozhevoi Korabl`" Project 159.
USS Zumbrota (SP-93/YP-93) was a motor boat in the United States Navy.
USS Geranium was a steamship acquired by the Union Navy during the American Civil War for the purpose of using her as a tugboat in support of Union ships on the blockade of Southern waterways. However, in addition to her tug duties, she also served as a picket ship, dispatch boat, supply runner and other duties assigned to her by the Navy.
USS Loeser was a Buckley-class destroyer escort of the United States Navy, named in honor of Lieutenant Commander Arthur E. Loeser (1903–1942).
USS Bagaduce (AT-21/ATO-21) was the lead ship of the Bagaduce class of fleet tugs for the United States Navy. She was the first ship of the U.S. Navy of that name, and is named for the Bagaduce River and a peninsula in Hancock County, Maine.
The Veer-class corvettes of the Indian Navy are a customised Indian variant of the Soviet Tarantul class. They form the 22nd Killer Missile Vessel Squadron.
The Bridgewater-class sloop was a class composed of two sloops built for the Royal Navy, HMS Bridgewater and HMS Sandwich. The ships were part of the Royal Navy's 1927 Build Programme as replacements for the Flower-class sloop.
