Imperial War Museum in the context of "Sir William Orpen"

The Norden Mk. XV, known as the Norden M series in U.S. Army service, is a bombsight that was used by the United States Army Air Forces (USAAF) and the United States Navy during World War II, and the United States Air Force in the Korean and the Vietnam Wars. It was an early tachometric design, which combined optics, a mechanical computer, and an autopilot for the first time to not merely identify a target but fly the airplane to it. The bombsight directly measured the aircraft's ground speed and direction, which older types could only estimate with lengthy manual procedures. The Norden further improved on older designs by using an analog computer that continuously recalculated the bomb's impact point based on changing flight conditions, and an autopilot that reacted quickly and accurately to changes in the wind or other effects.

Together, these features promised unprecedented accuracy for daytime bombing from high altitudes. During prewar testing the Norden demonstrated a 150 feet (46 m) circular error probable (CEP), an astonishing performance for that period. This precision would enable direct attacks on ships, factories, and other point targets. Both the Navy and the USAAF saw it as a means to conduct successful high-altitude bombing. For example, an invasion fleet could be destroyed long before it could reach U.S. shores.

The Signing of Peace in the Hall of Mirrors, Versailles, 28 June 1919 is an oil-on-canvas painting by Irish artist William Orpen, completed in 1919. It was one of the paintings commissioned from Orpen to commemorate the Peace Conference at Versailles in 1919. The work is held by the Imperial War Museum, in London.

HMS Belfast is a Town-class light cruiser that was built for the Royal Navy. She is now permanently moored as a museum ship on the River Thames in London and is operated by the Imperial War Museum.

Construction of Belfast, the first ship in the Royal Navy to be named after the capital city of Northern Ireland and one of ten Town-class cruisers, began in December 1936. She was launched on Saint Patrick's Day 1938. Commissioned in early August 1939 shortly before the outbreak of the Second World War, Belfast was initially part of the British naval blockade against Germany. In November 1939, Belfast triggered a German mine and, in spite of fears that she would be scrapped, spent more than two years undergoing extensive repairs. Belfast returned to action in November 1942 with improved firepower, radar equipment and armour. She saw action escorting Arctic convoys to the Soviet Union during 1943 and in December 1943 played an important role in the Battle of North Cape, assisting in the destruction of the German warship Scharnhorst. In June 1944, Belfast took part in Operation Overlord supporting the Normandy landings. In June 1945, she was redeployed to the Far East to join the British Pacific Fleet, arriving shortly before the end of the Second World War. Belfast saw further combat action in 1950–52 during the Korean War and underwent an extensive modernisation between 1956 and 1959. A number of further overseas commissions followed before she entered reserve in 1963.

The London Borough of Southwark (/ˈsʌðərk/ SUDH-ərk) in South London forms part of Inner London and is connected by bridges across the River Thames to the City of London and the London Borough of Tower Hamlets. It was created in 1965 when three smaller council areas were amalgamated under the London Government Act 1963. All districts of the area are within the London postal district. It is governed by Southwark London Borough Council.

The part of the South Bank within the borough is home to London Bridge terminus station and the attractions of The Shard, Tate Modern, Shakespeare's Globe and Borough Market that are the largest of the venues in Southwark to draw domestic and international tourism. Dulwich is home to the Dulwich Picture Gallery and the Imperial War Museum is in Elephant and Castle. Major districts include Bermondsey, Rotherhithe, Peckham, Camberwell, and Dulwich.

Kennington is a district in Central London, England. It is mainly within the London Borough of Lambeth, running along the boundary with the London Borough of Southwark, a boundary which can be discerned from the early medieval period between the Lambeth and St George's parishes of those boroughs respectively. It is located 1.4 miles (2.3 km) south of Charing Cross in Inner London and is identified as a local centre in the London Plan. It was a royal manor in the parish of St Mary, Lambeth in the county of Surrey and was the administrative centre of the parish from 1853. Proximity to central London was key to the development of the area as a residential suburb and it was incorporated into the metropolitan area of London in 1855.

Kennington is the location of three significant London landmarks: the Oval cricket ground, the Imperial War Museum, and Kennington Park. Its population at the United Kingdom Census 2011 was 15,106.

A barrel bomb is an improvised unguided bomb, sometimes described as a flying IED (improvised explosive device). They are typically made from a large barrel-shaped metal container that has been filled with explosives, possibly shrapnel, oil or chemicals as well, and then dropped from a helicopter or aeroplane. Due to the large amount of explosives (up to 1,000 kilograms (2,200 lb)), their poor accuracy, and indiscriminate use in populated civilian areas (including refugee camps), the resulting impacts have been devastating. Critics have characterised them as weapons of terror and illegal under international conventions.

Barrel bombs were used in different conflict zones including in 1948 and by the US military in Vietnam in the late 1960s. Starting in the 1990s, they were also used in Sri Lanka, Croatia and Sudan. Barrel bombs were used extensively by the Syrian Air Force during the Syrian civil war—bringing the weapon to widespread global attention—and later by the Iraqi forces during the Anbar campaign. Experts believe they will continue to be embraced by unstable nations fighting insurgencies since they are cheap to make and utilise the advantages of a government's airpower.
