HMCS "Norsyd" was a modified Flower-class corvette that served with the Royal Canadian Navy during the Second World War.
 She served primarily in the Battle of the Atlantic as a convoy escort.
 She was named for North Sydney, Nova Scotia, her name being a contraction of the city's name.
 This was due to a naming conflict with a Royal Australian Navy vessel.
 After the war she served as a merchant ship and then as a corvette in the Israeli Navy.
"Iowa" (SSN-797), a "Virginia"-class submarine , will be the fourth U.S. Navy vessel named for the state of Iowa.
 Secretary of the Navy Ray Mabus officially announced the name on September 2, 2015, during a news briefing at Iowa State University.
USS "Lynx" (AK-100) was a "Crater"-class cargo ship commissioned by the US Navy for service in World War II.
 "Lynx" was the third US Navy vessel to bear the name, but unlike previous ships this one was named after the constellation Lynx.
 She was responsible for delivering troops, goods and equipment to locations in the Asiatic-Pacific Theater.
USS "Monterey" (CG-61) is a "Ticonderoga"-class guided-missile cruiser in the United States Navy.
 It is the fourth US Navy vessel named for the Battle of Monterrey at Monterrey, Nuevo León during the Mexican-American War in 1846.
 It was built at Bath Iron Works in Maine.
USS "Rainier" (AE-5), the second US Navy vessel named after Mount Rainier, was laid down on 14 May 1940 by the Tampa Shipbuilding Co., Tampa, Fla., as "Rainbow" (MC hull 124); launched 1 March 1941; sponsored by Mrs. Robert E. Anderson; transferred to the US Navy on 16 April 1941; converted for use as an ammunition auxiliary; and commissioned as "Rainier" (AE-5) on 21 December 1941 at Norfolk, Va., Capt. William W. Meek in command.
USS "Concord" was a wooden-hulled, three-masted sloop-of-war of the United States Navy and was launched on 24 September 1828 from the Portsmouth Naval Shipyard in Kittery, Maine.
 She was the first US Navy vessel to bear the name 'Concord' and was so named after the town of Concord for its role at the beginning of the American Revolution.
 When empty, the vessel displaced a total of 700 tons.
 The "Concord" had a complement of 190 officers and seamen with an armament of 20 guns and saw service protecting American merchant ships and other interests in several places around the world.
 The ship and her crew, who also functioned as Marines, fought in the Seminole Wars in Florida.
 "Concord" ran aground while on a patrolling mission along the African coast.
 Despite determined efforts from the crew, with three losing their lives in the process, the "Concord" was unable to be refloated.
 It was the first ship christened by a woman.
 Sloop-of-war "Concord", launched in 1827, was "christened by a young lady of Portsmouth."
 This is the first known instance of a woman sponsoring a United States Navy vessel.
 Unfortunately, the contemporary account does not name this pioneer female sponsor (Ceremonial ship launching).
USS "Winslow" (Destroyer No. 53/DD-53) was an "O'Brien"-class destroyer built for the United States Navy prior to the American entry into World War I.
 The ship was the second US Navy vessel named in honor of John Ancrum Winslow, a US Navy officer notable for sinking the Confederate commerce raider  during the American Civil War.
HMCS "Frontenac" was a modified Flower-class corvette that served with the Royal Canadian Navy during the Second World War.
 She fought primarily in the Battle of the Atlantic as a convoy escort.
 She was named for Kingston, Ontario, but due to a naming conflict with a Royal Navy vessel, the name "Frontenac" was chosen to commemorate the city instead of naming it directly.
 Kingston is the county seat of Frontenac County, Ontario and the site of Fort Frontenac.
