White Ensign
The White Ensign, at one time called the St George's Ensign due to the simultaneous existence of a cross-less version of the flag, is an ensign flown on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field with the Union Flag in the upper canton.
The White Ensign is also flown by yachts of members of the Royal Yacht Squadron and by ships of Trinity House escorting the reigning monarch.
In addition to the United Kingdom, several other nations have variants of the White Ensign with their own national flags in the canton, with the St George's Cross sometimes being replaced by a naval badge omitting the cross altogether. Yachts of the Royal Irish Yacht Club fly a white ensign with an Irish tricolour in the first quadrant and defaced by the crowned harp from the Heraldic Badge of Ireland. The Flag of the British Antarctic Territory and the Commissioners' flag of the Northern Lighthouse Board place the Union emblem in the first quarter of a white field, omitting the overall red St George's Cross, but are not ensigns for use at sea.
History
English naval ensigns were first used during the 16th century, and were often striped in green and white, but other colours were also used to indicate different squadrons, including blue, red and tawny brown.. Later, there was usually a St George's Cross in the upper canton, or sewn across the field as on the modern White Ensign. These striped ensigns continued in use under the Stuart kings: the Naval ensign of 1623 is described as having "15 horizontal stripes alternately blue, white and yellow with a Cross of St George in the canton". This design fell out of use after 1630, with the introduction of the Red, White and Blue ensigns. The use of stripes continued in the red and white of both the flag of the Honourable East India Company, adopted in 1600, and of the 1775 Grand Union Flag that formed the basis for the modern flag of the United States of America, and the red, white and blue striped ensign that serves as the flag of Hawaii.The first recognisable White Ensign appears to have been in use during the 16th century, consisting of a white field with a broad St George's cross, and a second St. George's cross in the canton. By 1630 the white ensign consisted of simply a white field, with a small St George's cross in the canton, which was consistent with the red and blue ensigns of the time. In 1707, the St. George's cross was reintroduced to the flag as a whole, though not as broad as before, and the Union Flag was placed in the canton. There was also a version of this flag without the overall St George's cross, which appears to have been for use in home waters only, though this flag appears to have fallen out of use by 1720. In 1801, after the Act of Union 1800, the flag was updated to include the new Union Flag in the canton, and so took on the form as used today. The blue field of the Union Flag was darkened at this time at the request of the Admiralty, in the hope that the new flags would not require replacing as often as the previous design, due to fading of the blue. Throughout this period, the proportions of the flags changed. In 1687, the then Secretary of the Admiralty, Samuel Pepys, instructed that flags be of the ratio 11:18. In the early 18th century, the breadth of cloth had been reduced to 10 inches, so the flags became 5:9. In 1837, the breadth was reduced for the final time to 9 inches, giving the current ratio of 1:2.
Throughout this period in the history of the Royal Navy, the White Ensign was one of three ensigns in use, with each one being assigned to one of the three squadrons of the navy, according to its colour. Ships flew the colour of ensign corresponding to the squadron to which they were attached, which was in turn determined by the seniority of the admiral under whose command the ship sailed.
In 1864 the Admiralty decided to end the ambiguity caused by the Red Ensign being both a civil ensign and a naval ensign, and the White Ensign was reserved to the Royal Navy; the relevant Order in Council retained the option to use Red or Blue Ensigns in HM Ships if desired.
Current use
United Kingdom
Royal Navy ships and submarines wear the White Ensign at all times when underway on the surface. The White Ensign may also be worn on a gaff, and may be shifted to the starboard yardarm when at sea. When alongside, the White Ensign is worn at the stern, with the Union Jack flag flown as a jack at the bow, during daylight hours. The logo of Royal Navy features a waving White Ensign at the top.The White Ensign is worn at the mastheads when Royal Navy ships are dressed on special occasions such as the Queen's birthday, and may be similarly be worn by foreign warships when in British waters when dressed in honour of a British holiday or when firing a salute to British authorities. The White Ensign may also be worn by the boats of commissioned ships. Yachts of the Royal Yacht Squadron and the Trinity House vessels when escorting the British Monarch are also permitted to wear the White Ensign. in Trafalgar Square of London is customarily decorated with white ensigns on state occasions such as this St. George's Day in 2011
On land, the White Ensign is flown at all naval shore establishments, including all Royal Marines establishments. Permission has been granted to some other buildings with naval connections to fly the White Ensign. This includes the St Martin-in-the-Fields Anglican Church in Trafalgar Square, London, which is the parish church of the Admiralty. The Ensign is also displayed on the Cenotaph alongside the Union Jack flag and the Royal Air Force Ensign, in memory of the dead in the World Wars. Special permission was granted to any individual or body to fly the White Ensign to mark Trafalgar Day and the victory in the naval Battle of Trafalgar on its 201st anniversary in 2006.
The U.S. Navy destroyer is the only U.S. warship to fly the White Ensign along with the Stars and Stripes to honour her British namesake, the former prime minister. Isambard Kingdom Brunel's, although a merchant ship, appears to have worn the White Ensign, apparently because its first master brought it with him.
Commonwealth of Nations
The White Ensign was historically used, in its unaltered form, by the naval forces of Australia, Canada and New Zealand, with the Blue Ensign of each of these Dominions as a jack. In 1965, with the adoption of the Maple Leaf Canadian flag, Canada stopped using the White Ensign on its naval vessels in favour of the new flag. Following a reorganisation of the Canadian armed forces in 1968, a new "white ensign" was adopted, incorporating the Canadian flag in the canton and a badge in the fly. This flag, however, was until 2013 not used as the ensign, but as the jack, and also as the basis of the queen's colours of the Royal Canadian Navy. In May 2013 the Canadian "white ensign" became the ensign and the national flag the jack. Many Canadian veterans' organisations still use the original White and Blue Ensigns unofficially as symbols of history and heritage.During Australia's involvement in Vietnam, the RAN modified the White Ensign to create a uniquely Australian ensign which would avoid any confusion with UK vessels; Britain was not involved in the conflict. New Zealand followed suit in 1968. The modified RAN and RNZN White Ensigns incorporate the Union Flag in the first quarter, but with the Southern Cross designs from each national flag replacing St. George's Cross.
Several other Commonwealth navies also use naval ensigns with a visual connection to the White Ensign. For example, the Indian Navy and the South African Navy have both retained a cross on a white field, with their own national flag in the canton, in place of the Union Flag. The Royal Indian Marine used the unaltered White Ensign as its ensign from 1928 until 26 January 1950, when India became a republic within the Commonwealth. After that date, the RIN became the Indian Navy and the Union Jack in the canton was replaced with the Indian Tricolour. Apart from a brief period from 2001–2004, the Indian Navy has retained its variant of the White Ensign with one minor modification: the addition of the Lion Capital of Asoka crest in gold at the centre of the cross. Effective from 15 August 2014, the Indian national motto "Satyameva Jayate" is also added in gold script below the crest, correcting a long-standing omission.

Aside from being flown by the Arleigh Burke class destroyer, the British Naval Ensign is authorised to be used at the memorial on the campus of The Citadel. The White Ensign also flies over the British Cemetery on Ocracoke, North Carolina, which contains the remains of several seamen from, as well as a memorial to the lost naval trawler, which was sunk off the coast of Ocracoke Island in May 1942.Non military usage
