The 1930s was a highpoint for ocean-going liners.

Crossing the Atlantic by boat was the only way to reach the US, and competition between the French and British shipyards was never less than fierce, a focus for patriotic pride. The British Queen Mary and French Normandie epitomised the golden age of the ocean liners. They were among the floating Art Deco palaces that competed intensely to win the Blue Riband - a prize for the fastest Atlantic crossing. A Holy Grail for the two countries, this prize was also a great bit of marketing.

Based in Belfast at Queen’s Island, Harland and Wolff was a huge and very important shipbuilding company. The shipbuilding complex is only one of two yards left in the U.K. capable of building large merchant ships. The site occupies around 300 acres and is owned by a Norwegian company. The yard was most well known for building high-class transatlantic passenger liners and was considered to be the best in the world. The company has built over 1700 ships at four yards and has been in operation for over 135 years.
In 1912, due primarily to increasing political instability in Ireland, the company acquired another shipyard at Govan in Glasgow, Scotland. It bought the former London & Glasgow Engineering & Iron Shipbuilding Co's Middleton and Govan New shipyards in Govan and Mackie & Thomson's Govan Old Yard, which had been owned by William Beardmore and Company. The three neighbouring yards were amalgamated and redeveloped to provide a total of seven building berths, a fitting-out basin and extensive workshops. Harland & Wolff specialised in building tankers and cargo ships at Govan. The nearby shipyard of A. & J. Inglis was also purchased by Harland & Wolff in 1919, along with a stake in the company's primary steel supplier, David Colville & Sons. Harland & Wolff also established shipyards at Bootle in LiverpoolNorth Woolwich in London and Southampton. However, these shipyards were all eventually closed from the early 1960s when the company opted to consolidate its operations in Belfast.
In the First World War, Harland and Wolff built monitors and cruisers, including the 15-inch gun armed "large light cruiser" HMS Glorious. In 1918, the company opened a new shipyard on the eastern side of the Musgrave Channel which was named the East Yard. This yard specialised in mass-produced ships of standard design developed in the First World War.
...
The company started an aircraft manufacturing subsidiary with Short Brothers, called Short & Harland Limited in 1936. Its first order was for 189 Handley Page Hereford bombers built under licence from Handley Page for the Royal Air Force. In the Second World War, this factory built Short Stirling bombers as the Hereford was removed from service.

The shipyard was busy in the Second World War, building six aircraft carriers, two cruisers (including HMS Belfast) and 131 other naval ships; and repairing over 22,000 vessels. It also manufactured tanks and artillery components. It was in this period that the company's workforce peaked at around 35,000 people. However, many of the vessels built in this era were commissioned right at the end of World War II, as Harland and Wolff were focused on ship repair in the first three years of the war. The yard on Queen's Island was heavily bombed by the Luftwaffe in April and May 1941 causing considerable damage to the shipbuilding facilities and destroying the aircraft factory.

WW1

Just as Harland and Wolff and the White Star Line won the race for the Atlantic, the sinking of the Titanic sent shock-waves around the world. It was the greatest maritime disaster in history, but even greater carnage was to follow the war. The shipyard was now hurled into an arms race to build the biggest warships the world had ever seen. With CGI, original locations and historic film archive, Northern Ireland's global shipbuilding history is brought to life.

Workman, Clark and Company was a shipbuilding company based in Belfast. The company was established by Frank Workman and George Clark in Belfast in 1880. By 1895 it was the UK's fourth largest shipbuilder and by 1900 it was building transatlantic liners for major customers such as Cunard Line and Alfred Holt. It expanded further to meet demand during the First World War and was acquired by Northumberland Shipbuilding Company in 1918. After Northumberland Shipbuilding Company went into receivership in 1927, Workman, Clark and Company was resurrected only to go into receivership itself in 1935.

An amphibious transport dock, also called a landing platform dock (LPD), is an amphibious warfare ship, a warship that embarks, transports, and lands elements of a landing force for expeditionary warfare missions. Several navies currently operate this kind of ship. [image] The ships are generally designed to transport troops into a war zone by sea, primarily using landing craft, although invariably they also have the capability to operate transport helicopters

DSCA Stands for Defense Support of Civil Authorities. Every Hurricane season, the Navy and Marines stand up a joint task force to provide relief services after hurricanes. This task force is totally self-sufficient with the security, engineers, earth movers, transportation and administrative assets to provide aid in the event of a natural disaster.
Amphibious transport docks perform the mission of amphibious transports, amphibious cargo ships, and the older dock landing ships (LSD) by incorporating both a flight deck and a well deck that can be ballasted and deballasted to support landing craft or amphibious vehicles. The main difference between LSDs and LPDs is that while both have helicopter landing decks, the LPD also has hangar facilities for protection and maintenance. In the United States Navy, the newer class of LPD has succeeded the older classes of LSDs, and both the Navy and United States Marine Corps are looking to the LPD to be the basis of their new LX(R) program to replace their LSDs.

An amphibious ready group (ARG) of the United States Navy consists of a naval element—a group of warships known as an Amphibious Task Force (ATF)—and a landing force (LF) of U.S. Marines (and occasionally U.S. Army soldiers), in total about 5,000 people. Together, these elements and supporting units are trained, organized, and equipped to perform amphibious operations.

A typical U.S. Amphibious Readiness Group consists of:
The San Antonio class is a class of amphibious transport docks, also called a "landing platform, dock" (LPD), used by the United States Navy. These warships replace the Austin-class LPDs (including Cleveland and Trenton sub-classes), as well as the Newport-class tank landing ships, the Anchorage-class dock landing ships, and the Charleston-class amphibious cargo ships that have already been retired.

The Sea Control Ship (SCS) was a small aircraft carrier developed and conceptualized by the United States Navy under Chief of Naval Operations Elmo Zumwalt during the 1970sCurrently the term refers to naval vessels that can perform similar duties. The SCS was intended as an escort vessel, providing air support for convoys. It was canceled after budgetary cuts to the US Navy.

light aircraft carrier, or light fleet carrier, is an aircraft carrier that is smaller than the standard carriers of a navy. The precise definition of the type varies by country; light carriers typically have a complement of aircraft only one-half to two-thirds the size of a full-sized fleet carrier. A light carrier was similar in concept to an escort carrier in most respects, however light carriers were intended for higher speeds to be deployed alongside fleet carriers, while escort carriers usually defended convoys and provided air support during amphibious operations.

A mine countermeasures vessel or MCMV is a type of naval ship designed for the location of and destruction of naval mines which combines the role of a minesweeper and minehunter in one hull. The term MCMV is also applied collectively to minehunters and minesweepers. A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. A minehunter is a naval vessel that seeks, detects, and destroys individual naval mines. Minesweepers, on the other hand, clear mined areas as a whole, without prior detection of mines. A vessel that combines both of these roles is known as a mine countermeasures vessel (MCMV).

naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered.

Although international law requires signatory nations to declare mined areasprecise locations remain secret; and non-complying individuals may not disclose minelaying. While mines threaten only those who choose to traverse waters which may be mined, the possibility of activating a mine is a powerful disincentive to shipping. In the absence of effective measures to limit each mine's lifespan, the hazard to shipping can remain long after the war in which the mines were laid is over. Unless detonated by a parallel time fuze at the end of their useful life, naval mines need to be found and dismantled after the end of hostilities, an often prolonged, costly, and hazardous task.

Modern mines containing high explosives detonated by complex electronic fuze mechanisms are much more effective than early gunpowder mines requiring physical ignition. Mines may be placed by aircraft, ships, submarines, or individual swimmers and boatmen. Minesweeping is the practice of the removal of explosive naval mines, usually by a specially designed ship called a minesweeper using various measures to either capture or detonate the mines, but sometimes also with an aircraft made for that purpose. There are also mines which release a homing torpedo rather than explode themselves.

Avenger-class mine countermeasures ships are a class of 14 ships constructed for the United States Navy from 1987 to 1994, designed to clear mines from vital waterways. The ships have the hull designator MCM. The Avenger-class ships are being replaced by the Freedom and Independence-class littoral combat ships, as well as other MCM platforms, which use various unmanned air, surface, and undersea vehicles to detect and destroy naval mines at a standoff distance.

The Freedom class is one of two classes of the littoral combat ship program, built for the United States Navy. The Freedom class was proposed by a consortium formed by Lockheed Martin as "prime contractor" and by Fincantieri (project) through the subsidiary Marinette Marine (manufacturer) as a contender for a fleet of small, multipurpose warships to operate in the littoral zone. Two ships were approved, to compete with the Independence-class design offered by General Dynamics and Austal for a construction contract of up to 55 vessels.

Despite initial plans to only accept two each of the Freedom and Independence variants, the U.S. Navy has since announced plans to order up to 10 additional ships of each class, for a total 12 ships per class. As of 2016, five ships are active and an additional nine are either on order, under construction, or fitting out.

In early September 2016, the first four vessels of the LCS program were announced to be used as test ships rather than being deployed with the fleet. This includes Freedom and Fort Worth. In February 2020, the Navy announced that it plans to retire the first four LCS ships. This includes Independence class lead ship Independence and Coronado. On 20 June 2020, the US Navy announced that all four would be taken out of commission in March 2021, and will be placed in inactive reserve.

The Independence class is a class of littoral combat ships built for the United States Navy.

The hull design evolved from a project at Austal to design a high speed, 40 knot cruise ship. That hull design evolved into the high-speed trimaran ferry HSC Benchijigua Express and the Independence class was then proposed by General Dynamics and Austal as a contender for Navy plans to build a fleet of smaller, agile, multipurpose warships to operate nearshore in the littoral zone. Initially two ships were approved, to compete with Lockheed Martin's Freedom-class design.
