The Junkers Ju 288, originally known within the Junkers firm as the EF 074, was a German bomber project designed during World War II, which only ever flew in prototype form.
 The first of 22 development aircraft flew on 29 November 1940.
A Riesenflugzeug (plural "Riesenflugzeuge", German for "giant aircraft"), sometimes colloquially referred to in English as an R-plane, was a large World War I German bomber, possessing at least three aircraft engines, more usually being powered by four or more engines, sometimes of more than one make, model or power level.
 These were large multi-engine aircraft capable of flying several hours with larger bomb loads than the smaller "Grossflugzeug" bombers such as the Gotha G.V.
 Some of the earliest "Riesenflugzeuge" were given G-type designations before being redesignated, but a major distinction was that the requirements for the R-type specified that the engines had to be serviceable in flight.
 As a result, designs fell into two groups - those with the engines mounted centrally inside the fuselage using gearboxes and driveshafts to transfer the power to propellers mounted between the wings, and those with conventional powerplant installations mounted in large nacelles or the nose of the aircraft where engineers would be stationed for each group of engines.
 The transmission of power from the centrally mounted engines to the remote, most often wing-mounted propellers proved troublesome in practice and most operational examples of "Riesenflugzeug"-class aircraft were of the second type, as with the all-direct-drive Zeppelin-Staaken R.VI.
The Junkers Ju 87 or Stuka (from "Sturzkampfflugzeug", "dive bomber") was a German dive bomber and ground-attack aircraft.
 Designed by Hermann Pohlmann, it first flew in 1935.
 The Ju 87 made its combat debut in 1937 with the Luftwaffe's Condor Legion during the Spanish Civil War and served the Axis forces in World War II.
Bernhard Jope (10 May 1914 – 31 July 1995) was a German bomber pilot during World War II.
 He was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves of Nazi Germany.
 As part of Kampfgeschwader 40 (bomber wing), Jope flew missions across the North Sea and Atlantic Ocean in support of the German navy, damaging in October 1940 the RMS "Empress of Britain" .
 In 1943, he led Kampfgeschwader 100 in the attacks on the Italian battleship "Roma" , the British battleship HMS "Warspite" and cruiser HMS "Uganda" , and the US cruiser USS "Savannah" .
The SC 250 ("Sprengbombe Cylindrisch 250") was an air-dropped general purpose high-explosive bomb built by Germany during World War II and used extensively during that period.
 It could be carried by almost all German bomber aircraft, and was used to notable effect by the Junkers Ju 87 "Stuka" ("Sturzkampfflugzeug" or dive-bomber).
 The bomb's weight was about 250 kg, from which its designation was derived.
The Focke-Wulf Fw 191 was a prototype German bomber of World War II, as the Focke-Wulf firm's entry for the Bomber B advanced medium bomber design competition.
 Two versions were intended to be produced, a twin-engine version using the Junkers Jumo 222 engine and a four-engine variant which was to have used the smaller Daimler-Benz DB 605 engine.
 The project was eventually abandoned due to technical difficulties with the engines.
The Dornier Do Y was a German bomber of the 1930s, the second bomber design by Dornier Flugzeugwerke.
Werner Baumbach (27 December 1916 – 20 October 1953) was a German bomber pilot during World War II.
 He commanded the secret bomber wing Kampfgeschwader 200 (KG 200) of the Luftwaffe, the air force of Nazi Germany.
 Baumbach received the Knight's Cross of the Iron Cross with Oak Leaves and Swords for the destruction of over  gross register tons (GRT) of Allied shipping.
Hermann Hogeback (25 August 1914 – 15 February 2004) was a German bomber pilot during the Nazi era.
 He flew more than 100 operational sorties during the Spanish Civil War and 500 during World War II and was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves and Swords of Nazi Germany.
 Hogeback's last service position was commander) of the 6th Bomber Wing.
Walter Storp (2 February 1910 – 9 August 1981) was a German bomber pilot and commander of several bomber wings during World War II.
 He was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves.
 Storp reached the rank of Generalmajor and ended as the war as commander of the 5th Air Division in Norway.
