North Yorkshire in the context of "Northern England"

Lancashire (/ˈlæŋkəʃər/ LANG-kə-shər, /-ʃɪər/ -⁠sheer; abbreviated Lancs) is a ceremonial county in North West England. It is bordered by Cumbria to the north, North Yorkshire and West Yorkshire to the east, Greater Manchester and Merseyside to the south, and the Irish Sea to the west. The largest settlement is the city of Preston.

The county has an area of 3,079 square kilometres (1,189 sq mi) and had a population of 1,601,645 in 2024. Preston and Blackburn are located near the centre, Burnley in the east, the seaside resort of Blackpool on the Irish Sea coast in the west, and the city of Lancaster in the north. For local government purposes the county comprises a non-metropolitan county, with twelve districts, and two unitary authority areas: Blackburn with Darwen and Blackpool. Lancashire County Council and the two unitary councils collaborate through the Lancashire Combined County Authority. The county historically included the Furness and Cartmel peninsulas of Cumbria, northern Greater Manchester and Merseyside, and Warrington, but excluded the eastern part of the Forest of Bowland.

Eboracum (Classical Latin: [ɛbɔˈraːkũː]) was a fort and later a city in the Roman province of Britannia. In its prime it was the largest town in northern Britannia and a provincial capital. The site remained occupied after the decline of the Western Roman Empire and ultimately developed into the present-day city of York, in North Yorkshire, England.

Two Roman emperors died in Eboracum: Septimius Severus in 211 AD, and Constantius Chlorus in 306 AD.

York is a cathedral city in North Yorkshire, England, with Roman origins, sited at the confluence of the rivers Ouse and Foss. It has many historic buildings and other structures, such as a minster, castle and city walls, all of which are Grade I listed. It is the largest settlement and the administrative centre of the wider City of York district. It is located 27 miles (43 km) north-east of Leeds, 90 miles (140 km) south of Newcastle upon Tyne and 207 miles (333 km) north of London. York's built-up area had a recorded population of 141,685 at the 2021 census.

The city was founded under the name of Eboracum in AD 71. It then became the capital of Britannia Inferior, a province of the Roman Empire, and was later the capital of the kingdoms of Deira, Northumbria and Scandinavian York. In the Middle Ages it became the northern England ecclesiastical province's centre, and grew as a wool-trading centre. In the 19th century it became a major railway network hub and confectionery-manufacturing centre. In the Second World War York was bombed in the Baedeker Blitz. Although York was less targeted during the war than other, more industrialised northern cities, several historic buildings were gutted and restoration took place up until the 1960s.

Cumbria (/ˈkʌmbriə/ KUM-bree-ə) is a ceremonial county in North West England. It borders the Scottish council areas of Dumfries and Galloway and Scottish Borders to the north, Northumberland and County Durham to the east, North Yorkshire to the south-east, Lancashire to the south, and the Irish Sea to the west. Its largest settlement is the city of Carlisle.

Cumbria is predominantly rural, with an area of 6,769 km (2,614 sq mi) and a population of 510,680; this makes it the third-largest ceremonial county in England by area but the eighth-smallest by population. Carlisle is located in the north; the towns of Workington and Whitehaven lie on the west coast, Barrow-in-Furness on the south coast, and Penrith and Kendal in the east of the county. For local government purposes the county comprises two unitary authority areas, Westmorland and Furness and Cumberland. Cumbria was created in 1974 from the historic counties of Cumberland and Westmorland, the Furness area of Lancashire, and a small part of Yorkshire.

West Yorkshire is a metropolitan and ceremonial county in the Yorkshire and the Humber region of England. It borders North Yorkshire to the north and east, South Yorkshire and Derbyshire to the south, Greater Manchester to the south-west, and Lancashire to the west. The city of Leeds is the largest settlement.

The county has an area of 2,029 km (783 sq mi) and a population of 2.3 million, making it the fourth-largest ceremonial county by population. The centre of the county is urbanised, with Leeds located in the north-east, the city of Wakefield in the south-east, Huddersfield in the south-west, and the city of Bradford in the north-west. The outer areas of the county are rural. For local government purposes the county comprises five metropolitan boroughs: Bradford, Calderdale, Kirklees, Leeds, and Wakefield, which collaborate through West Yorkshire Combined Authority. The county was created in 1974, prior to which the area was within the West Riding of Yorkshire.

The Forest of Bowland, also known as the Bowland Fells and formerly the Chase of Bowland, is an area of gritstone fells, deep valleys and peat moorland, mostly in north-east Lancashire, England, with a small part in North Yorkshire (however roughly half of the area falls into the area of the historic West Riding of Yorkshire). It is a western outlier of the Pennines.

The Forest of Bowland was designated an Area of Outstanding Natural Beauty (AONB) in 1964. The AONB also includes a detached part known as the Forest of Pendle separated from the main part by the Ribble Valley, and anciently a royal forest with its own separate history. One of the best-known features of the area is Pendle Hill, which lies in Pendle Forest. There are more than 500 listed buildings and 18 scheduled monuments within the AONB.

The River Ribble runs through North Yorkshire and Lancashire in Northern England. It starts close to the Ribblehead Viaduct in North Yorkshire, and is one of the few that start in the Yorkshire Dales and flow westwards towards the Irish Sea (the Dee in Dentdale and the Twiss in Kingsdale being notable others).

South Yorkshire is a ceremonial county in the Yorkshire and the Humber region of England. It borders North Yorkshire and West Yorkshire to the north, the East Riding of Yorkshire to the north-east, Lincolnshire to the east, Nottinghamshire to the south-east, and Derbyshire to the south and west. The largest settlement is the city of Sheffield.

The county is largely urban, with an area of 1,552 km (599 sq mi) and a population of 1,430,623 in 2024. Sheffield is located in the south, with Rotherham immediately to the north-east. The city of Doncaster lies in the east, and Barnsley in the north. The far east and the west of the county are predominantly rural. For local government purposes the county comprises four metropolitan boroughs: Barnsley, Doncaster, Rotherham, and Sheffield. They collaborate through the South Yorkshire Mayoral Combined Authority.

An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack aircraft. AEW&C units are also used to carry out aerial surveillance over ground and maritime targets, and frequently perform battle management command and control (BMC2). When used at altitude, the radar system on AEW&C aircraft allows the operators to detect, track and prioritize targets and identify friendly aircraft from hostile ones in real-time and from much farther away than ground-based radars. Like ground-based radars, AEW&C systems can be detected and targeted by opposing forces, but due to aircraft mobility and extended sensor range, they are much less vulnerable to counter-attacks than ground systems.

AEW&C aircraft are used for both defensive and offensive air operations, and serve air forces in the same role as what the combat information center is to naval warships, in addition to being a highly mobile and powerful radar platform. So useful and advantageous is it to have such aircraft operating at a high altitude, that some navies also operate AEW&C aircraft for their warships at sea, either coastal- or carrier-based and on both fixed-wing and rotary-wing platforms. In the case of the United States Navy, the Northrop Grumman E-2 Hawkeye AEW&C aircraft is assigned to its supercarriers to protect them and augment their onboard command information centers (CICs). The designation "airborne early warning" (AEW) was used for earlier similar aircraft used in the less-demanding radar picket role, such as the Fairey Gannet AEW.3 and Lockheed EC-121 Warning Star, and continues to be used by the RAF for its Sentry AEW1, while AEW&C (airborne early warning and control) emphasizes the command and control capabilities that may not be present on smaller or simpler radar picket aircraft. AWACS (Airborne Warning and Control System) is the name of the specific system installed in the American Boeing E-3 Sentry and Japanese Boeing E-767 AEW&C airframes, but is often used as a general synonym for AEW&C.
