Junkers Ju 87G
Type: anti-tank and ground-attack aircraft.
History: The last combat variant and successor of the Junkers Ju 87D was the Ju 87G series. This Stuka variants were built by conversions of the ubiquitous D models.
Only the Ju 87G-1 became operational. The Ju 87G was a specialised anti-armour version, fitted with two BK 3.7 (Flak 18) guns hung under the wings just outboard of the landing gears. This 37-mm-gun was a formidable weapon weighting over 363 kg (800 lb) and in wide service as ground-based Flak (anti-aircraft artillery) equipment.

In June 1942 a trial installation was testet in a converted Ju 87D-5 and found more effective than the many other Luftwaffe anti-tank aircraft such as the Henschel Hs 129 and Junkers Ju 88P. Fed by clips of six rounds, the BK 3.7 had a muzzle velocity with armour-piercing ammunition exceeding 850 m (2,790 ft) per second, and the greatest exponent of the Ju 87G-1, Hans-Ulrich Rudel, was ultimately credited with the personal destruction of 519 Russian armoured vehicles. It was he who, despite being shot down 30 times, flew 2,530 combat missions and continued to lead Stuka formatiions in daylight long after other Stuka groups had replaced their vulnerable aircraft with the Focke-Wulf Fw 190.
The Ju 87G-1 could carry bombs instead of guns, but had no dive-breakes. The removal of dive-bombing equipment made the G-1 most unrepresentative among Stuka variants.
Another variant produced by converting aircraft of the Ju 87D series was the Ju 87H dual-control trainer. No trainer had been considered necessary in the early days of the Ju 87 series, but by 1943 the art of surviving in the type had become so specialised and important on the Eastern Front that even experienced bomber and fighter pilots had to go out with a Ju 87 instructor before taking their places in the decimated ranks of the 'Stukagruppen'.
