During the early to mid-stages of the Second World War, the Stuka (short for "sturzkampfflugzeug" or dive-bomber) struck terror in the hearts and minds of soldiers and civilians alike. The Stuka was a rugged machine, designed to swoop down and destroy its target using 500-lb bombs or tear into them using 37mm flak guns mounted underneath the wings.

Flying at 4,600 meters (15,000 ft), the pilot of a Stuka located his target through a bombsight window in the cockpit floor. After opening the dive brakes and slowing his throttle, he then rolled the aircraft 180 degrees, automatically nosing the aircraft into a dive. Red tabs protruded from the upper surfaces of the wing as a visual indicator to the pilot that in case of a g induced black-out, the automatic dive recovery system would be activated.

The Stuka dived at a 60 - 90 degree angle, accelerating to 600 km/h (350 mph). When the aircraft was reasonably close to the target, a light on the contact altimeter came on to indicate the bomb-release point, usually at a minimum height of 450 m (1,500 ft). The pilot released the bomb by depressing a knob on the control column to release weapons and to initiate the automatic pull-out mechanism. A clutch located under the fuselage would swing the bomb out of the way of the propeller, and the aircraft would automatically begin a 6g pullout.

Once the nose was above the horizon, dive brakes were retracted, the throttle was opened, and the propeller was set to climb. The pilot regained control and resumed normal flight. The remaining bombs under the wings were used for other targets.

Pictured here is a 1:72 scale replica of a Junkers Ju 87G-2 "Kanonenvogel" dive-bomber that was piloted by Hans Ulrich Rudel, Gruppenkommandeur of IIII/Sturzkampfgeschwader 2 "Immelmann", then deployed to Budapest-Ferihegy, Hungary, during October 1944. Sold Out!

Historical Account: "The Cannon Bird" - With the G variant, the aging air frame of the Ju 87 found new life as an anti-tank aircraft. This was the final operational version of the Stuka, and was deployed on the Eastern Front. The reverse in German military fortunes after 1943 and the appearance of huge numbers of well-armored Soviet tanks caused Junkers to adapt the existing design to combat this new threat. The Henschel Hs 129B had proved a potent ground attack weapon, but its large fuel tanks made it vulnerable to enemy fire, prompting the RLM to say "that in the shortest possible time a replacement of the Hs 129 type must take place." With Soviet tanks the priority targets, the development of a further variant as a successor to the Ju 87D began in November 1942. On November 3rd, Milch raised the question of replacing the Ju 87, or redesigning it altogether. It was decided to keep the design as it was, but the power-plant was upgraded to a Junkers Jumo 211J, and two 30 mm (1.2 in) cannons were added. The variant was also designed to carry a 1,000 kg (2,200 lb) free-fall bomb load. Furthermore, the armored protection of the Ilyushin Il-2 Sturmovik - a feature pioneered by the 1916-17 origin Junkers J.I all-metal sesquiplane of World War I Imperial Germany's Luftstreitkrafte - was copied to protect the crew from ground fire now that the Ju 87 would be required to conduct low level attacks.

Hans-Ulrich Rudel, a Stuka ace, had suggested using two 37 mm (1.46 in) Flak 18 guns, each one in a self-contained under-wing gun pod, as the Bordkanone BK 3,7, after achieving success against Soviet tanks with the 20 mm MG 151/20 cannon. These gun pods were fitted to a Ju 87 D-1, W.Nr 2552. The first flight of the machine took place on January 31st, 1943, piloted by Stepp. The continuing problems with about two dozen of the Ju 88P-1 and slow development of the Henschel Hs 129B-3, each of them equipped with a large, PaK 40-based, autoloading Bordkanone 7,5 7.5 cm (2.95 in) cannon in a conformal gun pod beneath the fuselage, meant the Ju 87G was put into production. In April 1943, the first production Ju 87 G-1s were delivered to front line units. The two 37 mm (1.46 in) Bordkanone BK 3,7 cannons were mounted in under-wing gun pods, each loaded with two six-round magazines of armor-piercing tungsten carbide-cored ammunition. With these weapons, the Kanonenvogel ("cannon-bird"), as it was nicknamed, proved very successful in the hands of Stuka aces such as Rudel. The G-1 was converted from older D-series air frames, retaining the smaller wing, but without the dive brakes. The G-2 was similar to the G-1 except for use of the extended wing of the D-5. 208 G-2s were built and at least a further 22 more were converted from D-3 air frames. Only a handful of production Gs were committed in the Battle of Kursk. On the opening day of the offensive, Hans-Ulrich Rudel flew the only "official" Ju 87 G, although a significant number of Ju 87D variants were fitted with the 37 mm (1.46 in) cannon, and operated as unofficial Ju 87 Gs before the battle. In June 1943, the RLM ordered 20 Ju 87Gs as production variants. The G-1 later influenced the design of the Fairchild Republic A-10 Thunderbolt II, with Hans Rudel's book, Stuka Pilot being required reading for all members of the A-X project.
