Landing Ship Medium
Landing Ship Medium (LSM) were amphibious assault ships of the United States Navy in World War II. Of a size between that of Landing Ships Tank (LST) and Landing Craft Infantry (LCI), 558 LSMs were built for the USN between 1944 and 1945. The majority of vessels built on this frame were regular transports, while several dozen were converted during construction to specialized roles. Most LSMs were scrapped during the Cold War, but several were sold by the United States Department of Defense to foreign nations or private shipping companies.

Amphibious Assault Ship
An amphibious assault ship is a type of amphibious warfare ship employed to land and support ground forces on enemy territory by an amphibious assault. The design evolved from aircraft carriers converted for use as helicopter carriers (and, as a result, are often mistaken for conventional fixed-wing aircraft carriers). Modern ships support amphibious landing craft, with most designs including a well deck. Coming full circle, some amphibious assault ships also support V/STOL fixed-wing aircraft, now having a secondary role as aircraft carriers. The role of the amphibious assault ship is fundamentally different from that of a standard aircraft carrier: its aviation facilities have the primary role of hosting helicopters to support forces ashore rather than to support strike aircraft. However, some are capable of serving in the sea-control role, embarking aircraft like Harrier or the new F-35B variant of the Lightning II fighters for combat air patrol and helicopters for an ...

Operation Crossroads
Operation Crossroads was a pair of nuclear weapon tests conducted by the United States at Bikini Atoll in mid-1946. They were the first nuclear weapon tests since Trinity in July 1945, and the first detonations of nuclear devices since the atomic bombing of Nagasaki on August 9, 1945. The purpose of the tests was to investigate the effect of nuclear weapons on warships. The Crossroads tests were the first of many nuclear tests held in the Marshall Islands, and the first to be publicly announced beforehand and observed by an invited audience, including a large press corps. They were conducted by Joint Army/Navy Task Force One, headed by Vice Admiral William H. P. Blandy rather than by the Manhattan Project, which had developed nuclear weapons during World War II. A fleet of 95 target ships was assembled in Bikini Lagoon and hit with two detonations of Fat Man plutonium implosion-type nuclear weapons of the kind dropped on Nagasaki in 1945, each with a yield of .

5"/38 Caliber Gun
The Mark 12 5"/38 caliber gun was a United States dual-purpose naval gun, but also installed in single-purpose mounts on a handful of ships. The 38 caliber barrel was a mid-length compromise between the previous United States standard 5"/51 low-angle gun and 5"/25 anti-aircraft gun. United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 38 calibers long. The increased barrel length provided greatly improved performance in both anti-aircraft and anti-surface roles compared to the 5"/25 gun. However, except for the barrel length and the use of semi-fixed ammunition, the 5"/38 gun was derived from the 5"/25 gun. Both weapons had power ramming, which enabled rapid fire at high angles against aircraft. The 5"/38 entered service on , commissioned in 1934, the first new destroyer design since the last ''Clemson'' was built in 1922. The base ring mount, which improved the effective rate of fire, entered service on , commissioned i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Landing Ship Medium Clive Steele (AV 1356)
The Australian landing ship medium ''Clive Steele'' (AV 1356) was a United States Navy landing ship medium which was later sold to Australia and operated by the Australian Army. The ship was built by the Brown Shipbuilding Company in Houston, Texas and was commissioned into the United States Navy (USN) as USS ''LSM-547'' on 25 January 1946. She was decommissioned on 11 March 1947 and laid up in the Atlantic Reserve Fleet. Recommissioned on 22 September 1950 and served during the Korean War between 1951 and 1953. She was decommissioned on 5 July 1955 and laid up in the Pacific Reserve Fleet. The ship was purchased by the Australian Army on 26 January 1960 and was named ''Clive Steele'' (AV 1356) in honour of the Australian World War II general Clive Steele. The ship was one of four LSMs operated by the newly formed 32nd Small Ship Squadron, Royal Australian Engineers. From 1960 to 1970 she performed routine duties in support of the Australian Army, and carried equipment between po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Landing Ship Medium Brudenell White (AV 1354)
The Australian landing ship medium ''Brudenell White '' (AV 1354) was a United States Navy landing ship medium which was later sold to Australia and operated by the Australian Army. The ship was built by the Brown Shipbuilding Company in Houston, Texas and was commissioned into the United States Navy (USN) as USS ''LSM-477'' on 3 April 1945. She was assigned to the Pacific Theater of Operations and performed occupation duty following the end of the war. She was decommissioned on 15 May 1946 and laid up in the Pacific Reserve Fleet.

USS Hunting
USS ''Hunting'' (E-AG-398) was built as the ''LSM-398'' at the Charleston Navy Yard and launched in the first week of 1945. After service in the Atlantic as a landing ship the vessel was converted in 1953 to a sonar research vessel for the Naval Research Laboratory. ''Hunting'' was unique among Navy research vessels of the time in having a center well through which large towed "fish" could be transported and lowered to operating depths. The work contributed to sonar improvements and understanding ocean acoustics. After sale by the Navy in 1963 the vessel operated as a dredge until out of documentation in 1983. Landing ship (1945-1953) Launched as the ''LSM-398'' by the Charleston Navy Yard, on 6 January 1945; sponsored by Mrs. T. B. Thompson; and commissioned on 6 August 1945. Based at Little Creek, Virginia, the ship operated as a part of the Amphibious Fleet in the Atlantic, taking part in many training assaults (such as "Exercise Seminole" in 1947) in the Caribbean Sea and o ...

Ryukyu Islands
The , also known as the or the , are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ōsumi, Tokara, Amami, Okinawa, and Sakishima Islands (further divided into the Miyako and Yaeyama Islands), with Yonaguni the westernmost. The larger are mostly high islands and the smaller mostly coral. The largest is Okinawa Island. The climate of the islands ranges from humid subtropical climate (Köppen climate classification ''Cfa'') in the north to tropical rainforest climate (Köppen climate classification ''Af'') in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs. The Ōsumi and Tokara Islands, the northernmost of the isla ...
