Radar

Radar is a system that uses electromagnetic waves to identify the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, motor vehicles, weather formations, and terrain. The term RADAR was coined in 1941 as an acronym for radio detection and ranging. The term has since entered the English language as a standard word, radar, losing the capitalization. Radar was originally called RDF (Radio Direction Finder) in the United Kingdom.

A radar system has a transmitter that emits either microwaves or radio waves that are reflected by the target and detected by a receiver, typically in the same location as the transmitter. Although the signal returned is usually very weak, the signal can be amplified. This enables radar to detect objects at ranges where other emissions, such as sound or visible light, would be too weak to detect. Radar is used in many contexts, including meteorological detection of precipitation, measuring ocean surface waves, air traffic control, police detection of speeding traffic, and by the military.

E-3 Sentry

The Boeing E-3 Sentry is an American military airborne warning and control system (AWACS) aircraft that provides all-weather surveillance, command, control and communications, to the United States, United Kingdom, France, Saudi Arabia, and NATO air defense forces. Production ended in 1992 after 68 had been built.

The E-3 Sentry is a modified Boeing 707-320B Advanced commercial airframe. Modifications included a rotating radar dome, single-point ground, and air refueling points. The dome is 30 feet (9.1 m) in diameter, six feet (1.8 m) thick at the center, and is held 14 feet (4.2 m) above the fuselage by two struts.

The dome weighs approximately 1.5 tons and provides 1.5 tons of lift. It contains a hydraulically rotated antenna system that permits the AN/APY-1/2 passive electronically scanned array radar system to provide surveillance from the Earth's surface up into the stratosphere, over land or water. Generators on each of the four engines provide the one megawatt of power required by the radar. The Pulse Doppler radar has a range of more than 250 miles (400 km) for low-flying targets at its operating altitude (essentially to the radar horizon), and the Pulse(BTH) beyond the horizon radar has a range of approximately 400 miles (650 km) for aerospace vehicles flying at medium to high altitudes (essentially above the radar horizon). The radar combined with an SSR subsystem can look down to detect, identify and track enemy and friendly low-flying aircraft by eliminating ground clutter returns.

The Sky Suspended: A Fighter Pilot's Story (Paperback)


In 1939, at the age of nineteen, Jim Bailey was conscripted into the RAF to train as a fighter pilot. What happened over the next five years to Jim and the men he met, the men who fought, died, and survived, is related with candor and quiet modesty in this book. It describes the youthful heroism of his companions, and he captures the atmosphere of everyday life on the ground in wartime Britain, as well as the air battles.

'A haunting book brilliant' Financial Mail 'It is worthy to stand with the best of air-war memoirs. I've never read a book that was anything like it' Samuel Hynes 'As poignant [a piece of aviation literature] as I have ever read' Sunday Correspondent 'The best airmen are mostly simple people but occasionally there arises one, a poet, a philosopher, who succeeds in lending coherent reason to their love every airman of our age will feel [Jim Bailey has] given wings to his inmost thoughts' Group Captain Peter Townsend

Jim Bailey was born into a world in which 'ordinary' people were regarded as no more than cannon fodder, and well-heeled generals could do no wrong. But attitudes were changing by the time he decided to fight for King and Country in the early autumn of 1939. Now, ordinary mortals such as himself were to be given responsibilities previously unheard of, and tasked with nothing less than saving the country from Nazi tyranny. In a book first published in 1964 we learn what it was like to serve for five years as a fighter pilot, marvelling at the heroics of companion fliers and sometimes witnessing their deaths. Bailey describes his own part in the Battle of Britain and other aerial skirmishes with understated modesty but he evocatively captures the atmosphere of life in the air and on the ground in wartime Britain. His account has become a classic of its type and will long endure.(Kirkus UK)

B-2 Stealth

The Northrop Grumman B-2 Spirit (also known as the Stealth Bomber) is a multirole heavy bomber with "low observable" stealth technology capable of penetrating dense anti-aircraft defenses to deploy both conventional and nuclear weapons. Because of its astronomical capital and operations costs, the project was controversial in Congress and among Pentagon brass during its development and placement into service. In time, Congress scaled back initial plans to purchase 132 of the bombers. By the early 1990s the United States elected to purchase just 21 of the bombers at US$737 million per aircraft. Total program cost averaged US$2.1 billion per aircraft in 1997 dollars.

The B-2 is operated exclusively by the United States Air Force with none in the Air Force Reserves. Though originally designed in the 1980s for Cold War operations scenarios, B-2s have been used in combat to drop bombs on Kosovo in the late 1990s, and see continued use during the ongoing Wars in Iraq and Afghanistan.

Featuring formidable design specifications, a two officer crew aboard the bomber can drop up to eighty 500-pound class JDAM "smart" bombs, or sixteen 2,600-pound B83 nuclear bombs in a single pass through extremely dense anti-aircraft defenses. The bomber has been a prominent public spectacle at air shows since the 1990s. It has been the subject of espionage and counter-espionage activity. [wiki]

F-20

The F-20 Tigershark (initially F-5G) was a privately financed light fighter, designed and built by Northrop. Its development began in 1975 as a further evolution of Northrop's F-5E Tiger II, featuring a new engine that greatly improved overall performance, and a modern avionics suite including a powerful and flexible radar. Compared with the F-5E, the F-20 was much faster, gained beyond visual range air-to-air capability, and had a full suite of air-to-ground modes capable of firing most U.S. weapons. With these improved capabilities, the F-20 became competitive with contemporary U.S. fighter designs like the F-16 Fighting Falcon, but was much less expensive to purchase and operate.
