Invasion stripes
Invasion stripes were alternating black and white bands painted on the fuselages and wings of Allied aircraft during World War II to reduce the chance that they would be attacked by friendly forces during and after the Normandy Landings. Three white and two black bands were wrapped around the rear of a fuselage just in front of the empennage and from front to back around the upper and lower wing surfaces.
After a study concluded that the thousands of aircraft involved in the invasion would saturate and break down the IFF system, the marking scheme was approved on May 17, 1944, by Air Chief Marshal Sir Trafford Leigh-Mallory, commanding the Allied Expeditionary Air Force. A small-scale test exercise was flown over the OVERLORD invasion fleet on June 1, to familiarise the ships' crews with the markings, but for security reasons, orders to paint the stripes were not issued to the troop carrier units until June 3 and to the fighter and bomber units until June 4.
Stripes were applied to fighters, photo-reconnaissance aircraft, troop carriers, twin-engined medium and light bombers, and some special duty aircraft. They were not painted on four-engined heavy bombers of the U.S. Eighth Air Force or RAF Bomber Command, as there was little chance of mistaken identity, the Luftwaffe having few such bombers. The order affected all aircraft of the Allied Expeditionary Air Force, the Air Defence of Great Britain, gliders, and support aircraft such as Coastal Command air-sea rescue aircraft whose duties might entail their overflying Allied anti-aircraft defenses.
One month after D-Day, the stripes were ordered removed from planes' upper surfaces to make them more difficult to spot on the ground at forward bases in France. They were completely removed by the end of 1944 after achieving total air supremacy over France.
Marking description
The stripes were five alternating black and white stripes. On single-engine aircraft each stripe was to be wide, placed inboard of the roundels on the wings and forward of the leading edge of the tailplane on the fuselage. National markings and serial number were not to be obliterated. On twin-engine aircraft the stripes were wide, placed outboard of the engine nacelles on the wings, and forward of the leading edge of the tailplane around the fuselage. However, American aircraft using the invasion stripes very commonly had some part of the added "bar" section of their post-1942 roundels overlapping the invasion strips on the wings.In most cases the stripes were painted on by the ground crews; with only a few hours' notice, few of the stripes were "masked". As a result, depending on the abilities of the "erks", the stripes were often far from neat and tidy.
Operation Starkey
The stripes for this two-day deception operation in 1943 were black from the wing tip to a position on the wing where the chord is 5 feet, then four bands of alternating white and black. This was the same for the upper and lower surfaces. These were applied to all aircraft operating at low level. For single engine aircraft the stripes were 18 inches in width. For twin engine aircraft, including the Westland Whirlwind, the stripes were 24 inches in width.Hawker Typhoon
An earlier use of black and white bands was on the Hawker Typhoon and early production Hawker Tempest Mark Vs. The aircraft had a similar outline when seen from above and below to the Focke-Wulf Fw 190 and the bands were added to aid identification in combat. The order was promulgated on 5 December 1942. At first they were applied by unit ground crews, but they were soon being painted on at the factory. Four black stripes separated by three white, underwing from the wingroots. From early 1943 the Typhoons also had a yellow, stripe on each of the upper wings, centred on the inner cannon. All of these markings were officially abandoned 7 February 1944.''Luftwaffe's'' Jagdverband 44
The late-war specialized all-jet Luftwaffe fighter squadron, Jagdverband 44, possessed a number of Fw 190 D piston-engined fighters to protect their units' Messerschmitt Me 262 jet fighters during the jets' takeoff and landing operations, as the jets were most vulnerable to Allied piston-engined fighter attack at those times. The Fw 190D aircraft of this so-called Platzschutzstaffel used a color scheme featuring solid red-painted areas under the wings and around the rear fuselage areas, within which narrow white stripes running fore-to-aft inder the wings and "vertically" around the fuselage areas were painted, to identify them as "friendly" Luftwaffe fighters.This was done for similar reasons as the "invasion stripes" had been used in Operation Overlord ten months earlier over Normandy. The Staffel was nicknamed Die Papagei-Staffel - it is not known, however, if the earlier use of Würger by the Focke-Wulf aircraft firm itself for its original Fw 190A radial-engined initial subtype had any bearing on the JV 44 unit's Platzschutzstaffel nickname.
Korea
Invasion stripes were re-introduced on British and Australian Fleet Air Arm aircraft operating during the Korean War in 1950.Similar stripes were also used early in the war on F-86 Sabres of the 4th Fighter Interceptor Wing as a deviation from the standard yellow stripes.
Suez
The stripes were used again by the Royal Air Force, the Royal Navy's Fleet Air Arm, the French Naval Aviation and the French Air Force during the Suez operation of 1956, mostly to distinguish UK and French aircraft from Egypt's British-made planes. Single-engined aircraft had yellow/black/yellow/black/yellow stripes one foot wide; multi-engined aircraft had the same pattern with stripes. Israel, who was a co-belligerent with Britain and France, did not paint Suez Stripes on their aircraft.Czechoslovakia
During the Soviet-led invasion of Czechoslovakia in 1968, the Soviet Union used a series of white stripes on the armoured vehicles of its invasion forces because they used predominantly the same types of combat vehicles as the armed forces of Czechoslovakia. The markings consisted of one long white strip in the middle of the vehicle from the front and across the roof all the way to the back with two additional strips in the middle of both sides. This is similar to the markings applied on most Soviet tanks and armoured fighting vehicles fighting in Berlin in 1945 during the Second World War to prevent friendly fire from Western Allied aircraft that flew over the city to conduct bombing raids until its fall.In addition to that, certain Soviet Air Force's aircraft, such as the MiG-21 fighters, were given two red stripes on their fuselages and vertical stabilisers, also because these types of aircraft were used by the Czechoslovak Air Force.
