Landing Ship Medium
A Landing Ship Medium (LSM) was originally an amphibious assault ship of the United States Navy in World War II. Of a size between that of Landing Ships Tank and Landing Craft Infantry, 558 LSMs were built for the USN between 1944 and 1945. Most of the vessels built on this frame were regular transports, but 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. OPNAV N95 established a new LSM program in 2020. The new LSM will be long, able to operate at 22 knots and have a range of . The cost will be much lower than traditional amphibious shipping, according to a story in the March 2023 ''Marine Corps Gazette''. The piece suggests that a MLR (Marine Littoral Regiment) would need nine LSMs. As a comparison the ''Jason''-class of the Greek Navy is about long, with a top speed of 18 knots ''LSM-1' ...

Amphibious Assault Ship
An amphibious assault ship is a type of warship employed to land and support ground forces on enemy territory during an armed conflict. The design evolved from aircraft carriers converted for use as helicopter carriers (which, as a result, are often mistaken for conventional fixed-wing aircraft carriers). Modern designs support amphibious landing craft, with most designs including a well deck. Like the aircraft carriers they were developed from, some amphibious assault ships also support V/STOL fixed-wing aircraft and have 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 ...

Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seebach M ...

5"/38 Caliber Gun
The Mark 12 5"/38-caliber gun was a United States dual purpose gun, dual-purpose Naval artillery, naval gun, but also installed in single-purpose mounts on a handful of ships. The 38-Caliber (artillery), caliber barrel was a mid-length compromise between the previous United States standard 5"/51 caliber gun, 5"/51 low-angle gun and 5-inch/25-caliber gun, 5"/25 anti-aircraft gun. United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 38 Caliber (artillery), 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 Shell (projectile)#Separate loading cased charge, 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 n ...

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 a ...
