Ju 87 G
With the G variant, the aging airframe 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-armoured 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 87 D 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 powerplant 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 armoured 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 the Ju 88P-1s equipped with BK 7.5 75 mm (2.95 in) cannon meant the Ju 87 G was put into production. In April 1943 the first production Ju 87 G-1s were delivered to front-line units.
