High level bombing

Last updated
USAF high level bombing through clouds over North Vietnam, 14 June 1966. An EB-66 tactical jamming aircraft leads four F-105 fighter-bombers as a Pathfinder. Also called synchronous radar bombing or buddy bombing, this method required the EB-66 navigator to use his K-5 radar bombing navigation system to detect the target and send a signal tone to the F-105s to drop their bombs. Throughout the bombing run, the Pathfinder employed its S-band jammers to suppress radar-controlled anti-aircraft guns. Radar film coverage from Pathfinder missions was accumulated by the USAF for more sophisticated and refined targeting, bomb damage assessment and photographic reconnaissance of North Vietnam.

High level bombing (also called high-altitude bombing) is a tactic of dropping bombs from bomber aircraft in level flight at high altitude. The term is used in contrast to both World War II-era dive bombing [2] and medium or low level bombing.

Prior to the modern age of precision-guided munitions (PGMs), high level bombing was primarily used for strategic bombing—inflicting mass damage on the enemy's economy and population—not for attacks on specific military targets. High level bombing missions have been flown by many different types of aircraft, including medium bombers, heavy bombers, strategic bombers and fighter-bombers.

The choice to use high level bombing as an offensive tactic of aerial warfare is dependent not only upon the inherent accuracy and effectiveness of the bombing aircraft and their delivered ordnance on the target, but also upon a target's air defense capabilities. From the 1940s onward, radar in particular became a powerful new defensive early warning tool, and a serious threat to attacking aircraft when they flew at higher altitudes towards their target.

Bombing from medium to high altitudes, especially in the post-World War II era with sophisticated surface-to-air missiles, interceptor aircraft and radars exposes attacking bomber aircraft to greater risks of detection, interception and destruction. During World War II, various methods were employed to protect high level bombers from flak, fighter aircraft and radar detection, including defensive armament, escort fighters, chaff and electronic jamming. Modern stealth aircraft technologies, for example, can alleviate some risks inherent to high level bombing missions, but are not a guarantee of success or permanent solution for the attackers.

World War II

High level bombers were primarily used by the Allies for carpet bombing (particularly later in the war), such as the bombing of Dresden or Tokyo. They were also deployed in other kinds of missions such as Operation Tidal Wave, Operation Crossbow, and the sinking of the Tirpitz.

After initial operations by day suffered heavy losses, the British switched to night-time sorties where the darkness gave some protection against German fighters. Arthur "Bomber" Harris's strategy for the RAF Bomber Command was to attack area targets that the bombers could be more certain of hitting at night, while the U.S. preferred daylight, precision bombing techniques. [3] The development since the 1930s of gyroscope-stabilised optical bombsights, such as the Norden bombsight, also helped the Allied air forces' ability to accurately strike their targets with medium- to high-altitude level bombing attacks.

Nazi Germany used high level bombers such as the Heinkel He 111, the Dornier Do 17 and multi-role aircraft such as the Junkers Ju 88 against the Allies in the Battle of Britain, [4] both for carpet bombing and for precision attacks on British radar stations as part of Operation Eagle. [5]

Cold War

During the Cold War, the United States and Soviet Union used several bomber designs, [6] but the bulk of their offensive forces were in the form of, respectively, the B-52 Stratofortress and Tu-95 Bear. The French equivalent was the Mirage IV, and the UK had its V bombers.

The U.S. Strategic Air Command (SAC) ordered massive high level bombing in Operation Rolling Thunder and Operation Menu [7] during the Vietnam War. [8]

A bomber is a military combat aircraft designed to attack ground and naval targets by dropping air-to-ground weaponry, launching torpedoes, or deploying air-launched cruise missiles. The first use of bombs dropped from an aircraft occurred in the Italo-Turkish War, with the first major deployments coming in the First World War and Second World War by all major airforces causing devastating damage to cities, towns, and rural areas. The first purpose built bombers were the Italian Caproni Ca 30 and British Bristol T.B.8, both of 1913. Some bombers were decorated with nose art or victory markings.

<span class="mw-page-title-main">Strategic bombing</span> Systematic aerial attacks to destroy infrastructure and morale

Strategic bombing is a military strategy used in total war with the goal of defeating the enemy by destroying its morale, its economic ability to produce and transport materiel to the theatres of military operations, or both. It is a systematically organized and executed attack from the air which can utilize strategic bombers, long- or medium-range missiles, or nuclear-armed fighter-bomber aircraft to attack targets deemed vital to the enemy's war-making capability. The term terror bombing is used to describe the strategic bombing of civilian targets without military value, in the hope of damaging an enemy's morale.

<span class="mw-page-title-main">Interceptor aircraft</span> Fighter aircraft classification; tasked with defensive interception of enemy aircraft

An interceptor aircraft, or simply interceptor, is a type of fighter aircraft designed specifically for the defensive interception role against an attacking enemy aircraft, particularly bombers and reconnaissance aircraft. Aircraft that are capable of being or are employed as both ‘standard’ air superiority fighters and as interceptors are sometimes known as fighter-interceptors. There are two general classes of interceptor: light fighters, designed for high performance over short range; and heavy fighters, which are intended to operate over longer ranges, in contested airspace and adverse meteorological conditions. While the second type was exemplified historically by specialized night fighter and all-weather interceptor designs, the integration of mid-air refueling, satellite navigation, on-board radar and beyond visual range (BVR) missile systems since the 1960s has allowed most frontline fighter designs to fill the roles once reserved for specialised night/all-weather fighters.

<span class="mw-page-title-main">Dive bomber</span> Bomber aircraft that dives directly at its targets

A dive bomber is a bomber aircraft that dives directly at its targets in order to provide greater accuracy for the bomb it drops. Diving towards the target simplifies the bomb's trajectory and allows the pilot to keep visual contact throughout the bomb run. This allows attacks on point targets and ships, which were difficult to attack with conventional level bombers, even en masse.

<span class="mw-page-title-main">Strategic bomber</span> Type of military aircraft

A strategic bomber is a medium- to long-range penetration bomber aircraft designed to drop large amounts of air-to-ground weaponry onto a distant target for the purposes of debilitating the enemy's capacity to wage war. Unlike tactical bombers, penetrators, fighter-bombers, and attack aircraft, which are used in air interdiction operations to attack enemy combatants and military equipment, strategic bombers are designed to fly into enemy territory to destroy strategic targets. In addition to strategic bombing, strategic bombers can be used for tactical missions. There are currently only three countries that operate strategic bombers: the United States, Russia and China.

<span class="mw-page-title-main">Airstrike</span> Attack on a specific objective by military aircraft during an offensive mission

An airstrike, air strike, or air raid is an offensive operation carried out by aircraft. Air strikes are delivered from aircraft such as blimps, balloons, fighter aircraft, attack aircraft, bombers, attack helicopters, and drones. The official definition includes all sorts of targets, including enemy air targets, but in popular usage the term is usually narrowed to a tactical (small-scale) attack on a ground or naval objective as opposed to a larger, more general attack such as carpet bombing. Weapons used in an airstrike can range from direct-fire aircraft-mounted cannons and machine guns, rockets and air-to-surface missiles, to various types of aerial bombs, glide bombs, cruise missiles, ballistic missiles, and even directed-energy weapons such as laser weapons.

<span class="mw-page-title-main">Norden bombsight</span> Targeting device on US bombers during World War II, Korean War, and Vietnam War

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 that directly measured the aircraft's ground speed and direction, which older bombsights 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.

The Pathfinders were target-marking squadrons in RAF Bomber Command during World War II. They located and marked targets with flares, which a main bomber force could aim at, increasing the accuracy of their bombing. The Pathfinders were normally the first to receive new blind-bombing aids like Gee, Oboe and the H2S radar.

<span class="mw-page-title-main">Bombsight</span> Aircraft system for aiming bombs

A bombsight is a device used by military aircraft to drop bombs accurately. Bombsights, a feature of combat aircraft since World War I, were first found on purpose-designed bomber aircraft and then moved to fighter-bombers and modern tactical aircraft as those aircraft took up the brunt of the bombing role.

Ground-directed bombing (GDB) is a military tactic for airstrikes by ground-attack aircraft, strategic bombers, and other equipped air vehicles under command guidance from aviation ground support equipment and/or ground personnel. Often used in poor weather and at night, the tactic was superseded by an airborne computer predicting unguided bomb impact from data provided by precision avionics Equipment for radar GDB generally included a combination ground radar/computer/communication system and aircraft avionics for processing radioed commands.

<span class="mw-page-title-main">Skip bombing</span> Bombing procedure

Skip bombing was a low-level bombing technique independently developed by several of the combatant nations in World War II, notably Italy, Australia, Britain, Soviet Union and the United States. It allows an aircraft to attack shipping by skipping the bomb across the water like a stone. Dropped at very low altitudes, the bomb never rises more than about 5 metres (16 ft) above the surface of the water, ensuring that it will hit the side of the ship as long as it is aimed correctly.

The Defence of the Reich is the name given to the strategic defensive aerial campaign fought by the Luftwaffe of Nazi Germany over German-occupied Europe and Germany during World War II. Its aim was to prevent the destruction of German civilians, military and civil industries by the Western Allies. The day and night air battles over Germany during the war involved thousands of aircraft, units and aerial engagements to counter the Allied strategic bombing campaign. The campaign was one of the longest in the history of aerial warfare and with the Battle of the Atlantic and the Allied Blockade of Germany was the longest of the war. The Luftwaffe fighter force defended the airspace of German-occupied territory against attack, first by RAF Bomber Command and then against the United States Army Air Forces (USAAF) in the Combined Bomber Offensive.
