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.

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 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 3 November, Erhard Milch raised the question of replacing the Ju 87, or redesigning it altogether. It was decided to keep the design as it was, but to upgrade the power plant to a Jumo 211J, and add two 30 mm (1.18 in) cannon. The variant was also designed to carry a 1,000 kg (2,200 lb.) free-fall bomb load. Furthermore, the armured protection of the Ilyushin Il-2 Sturmovik 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 as "Gustav the tank killer". The first flight of the machine took place on 31 January 1943, piloted by Hauptmann Hans-Karl Stepp. The continuing problems with about two dozens of the Ju 88P-1, and slow development of the Hs 129 B-3, each of them equipped with a large BK 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) cannons were mounted in under-wing gun pods, each loaded with a six round magazine of armor-piercing tungsten carbide ammunition. With these weapons, the Kanonenvogel ("cannon-bird"), as it was nicknamed, proved spectacularly 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.

Historical Account: "Age Before Beauty" - Despite the Stuka's vulnerability to enemy fighters having been exposed during the Battle of Britain, the Luftwaffe had no choice but to continue its development, as there was no replacement aircraft in sight. The result was the D-series. In June 1941, the RLM ordered five prototypes, the Ju 87 V21-25. A Daimler-Benz DB 603 powerplant was to be installed in the Ju 87 D-1, but it did not have the power of the Jumo 211 and performed "poorly" during tests and was dropped. The Ju 87 D-series featured two coolant radiators underneath the inboard sections of the wings, while the oil cooler was relocated to the position formerly occupied by the single, undernose "chin" coolant radiator. The D-series also introduced an aerodynamically refined cockpit with better visibility and space. Armor protection was increased and a new dual-barrel 7.92 mm (.312 in) MG 81Z machine gun with an extremely high rate of fire was installed in the rear defensive position. Engine power was increased again, the Jumo 211J now delivering 1,420 PS (1,044 kW or 1,400 hp). Bomb carrying ability was nearly quadrupled from 500 kg (1,100 lb) in the B-version to 1,800 kg (4,000 lb) in the D-version (max. load for short ranges, overload condition), a typical bomb load ranged from 500-1,200 kg (1,100-2,600 lb).

The internal fuel capacity of the Ju 87D was raised to 800 L (of which 780 L were usable) by adding wing tanks while retaining the option to carry two 300 L drop tanks. Tests at Rechlin-Larz Airfield revealed it made possible a flight duration of 2 hours and 15 minutes. With an extra two 300 L (80 US gal) fuel tanks, it could achieve four hours flight time.

The D-2 was a variant used as a glider tug by converting older D-series air frames. It was intended as the tropical version of the D-1 and had heavier armor to protect the crew from ground fire. The armor reduced its performance and caused the Oberkommando der Luftwaffe to "place no particular value on the production of the D-2". The D-3 was an improved D-1 with more armor for its ground-attack role. Some Ju 87 D-3s were designated D-3N or D-3 trop and fitted with night or tropical equipment. The D-4 designation applied to a prototype torpedo-bomber version, which could carry a 750-905 kg (1,653-1,995 lb) aerial torpedo on a PVC 1006 B rack - this setup would have had the capacity to carry the Luftorpedo LT 850, the German version of the well-proven Japanese Type 91 aerial torpedo of 848 kg (1,870 lb). The D-4 was to be converted from D-3 air frames and, in place of the carrier-specific Ju 87C series designs, operated from the aircraft carrier Graf Zeppelin. Other modifications included a flame eliminator and, unlike earlier D variants, two 20 mm MG 151/20 cannon, while the radio operator/rear gunner's ammunition supply was increased by 1,000 to 2,000 rounds.
