The Moray Firth is a roughly triangular inlet of the North Sea, north and east of Inverness, which is in the Highland council area of north of Scotland. It is the largest firth in Scotland, stretching from Duncansby Head in the north, in the Highland council area, and Fraserburgh in the east, in the Aberdeenshire council area, to Inverness and the Beauly Firth in the west. Therefore, three council areas have Moray Firth coastline: Highland to the west and north of the Moray Firth and Highland, Moray and Aberdeenshire to the south. The firth has more than 800 kilometres of coastline, much of which is cliff.

The Commander-in-Chief, Portsmouth, was a senior commander of the Royal Navy for hundreds of years. The commanders-in-chief were based at premises in High Street, Portsmouth from the 1790s until the end of Sir Thomas Williams's tenure, his successor, Sir Philip Durham, being the first to move into Admiralty House at the Royal Navy Dockyard, where subsequent holders of the office were based until 1969. Prior to World War I the officer holder was sometimes referred to in official dispatches as the Commander-in-Chief, Spithead.

The Messerschmitt Bf 109 is a German World War II fighter aircraft that was, along with the Focke-Wulf Fw 190, the backbone of the Luftwaffe's fighter force. The Bf 109 first saw operational service in 1937 during the Spanish Civil War and was still in service at the end of World War II in 1945. It was one of the most advanced fighters when it first appeared, with an all-metal monocoque construction, a closed canopy, and retractable landing gear. It was powered by a liquid-cooled, inverted-V12 aero engine. It was called the Me 109 by Allied aircrew and some German aces, even though this was not the official German designation.

Harwich Dockyard was a Royal Navy Dockyard at Harwich in Essex, active in the 17th and early 18th century. Owing to its position on the East Coast of England, the yard was of strategic importance during the Anglo-Dutch Wars; however, due to a lack of deep-water access and the difficulty of setting off from Harwich against an easterly wind, its usefulness was somewhat limited and its facilities remained small-scale compared to the other Royal Dockyards over the same period. Nonetheless, it remained actively involved in repairing and refitting the nation's warships, as well as building them: of the eighty ships built for the Royal Navy in Britain between 1660 and 1688, fourteen were built at Harwich Dockyard..

The bombardment of Cherbourg took place on June 25, 1944, during World War II, when ships from the United States Navy and the British Royal Navy attacked German fortifications in and near the city, firing in support of U.S. Army units that were engaged in the Battle of Cherbourg. In doing so, the Allied naval forces engaged in a series of duels with coastal batteries and provided close support to infantry as they fought to gain control of the city. The bombardment was initially scheduled to last just two hours but it was later extended by an hour to support army units attempting to break into Cherbourg's city streets. After the bombardment, German resistance lasted until June 29, when the port was eventually captured by the Allies. Afterwards, the task of clearing the port for use lasted several weeks.

Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications.

In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or battle group and defend them against powerful short-range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish Navy as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War.
