Once the Luftwaffe had lost air superiority on all fronts, the Ju 87 once again became an easy target for enemy fighter aircraft.

Early design

The Ju 87's principal designer, Hermann Pohlmann, held the opinion that any dive-bomber design needed to be simple and robust.

Ju 87 evolution

The design of the Ju 87 had begun in 1933 as part of the Sturzbomber-Programm. The Ju 87 was to be powered by the British Rolls-Royce Kestrel

The first Ju 87 prototype was built by AB Flygindustri in Sweden and secretly brought to Germany in late 1934. It was to have been completed in April 1935, but, due to the inadequate strength of the airframe, construction was not completed until October 1935. However, the mostly complete Ju 87 V1 W.Nr. 4921 (less non-essential parts) took off for its maiden flight on 17 September 1935. The aircraft originally did not carry any registration, but later was given the registration D-UBYR. The flight report, by Hauptmann Willy Neuenhofen

 and could rotate 90°.

The RLM was still not interested in the Ju 87 and was not impressed that it relied on a British engine. In late 1935, Junkers suggested fitting a DB 600 in-line engine, with the final variant to be equipped with the Jumo 210. This was accepted by the RLM as an interim solution. The reworking of the design began on 1 January 1936. The test flight could not be carried out for over two months due to a lack of adequate aircraft. The 24 January crash had already destroyed one machine.

The second prototype was also beset by design problems. It had its twin stabilizers removed and a single tail fin installed due to fears over stability. Due to a shortage of power plants, instead of a DB 600, a BMW "Hornet" engine was fitted. All these delays set back testing until 25 February 1936. By March 1936, the second prototype, the V2, was finally fitted with the Jumo 210Aa

, so Heinkel could only communicate with Udet by telephone. According to this version of the story, Heinkel warned Udet about the propeller's fragility. Udet failed to consider this, so in a dive, the engine oversped and the propeller broke away.
Immediately after this incident, Udet announced the Stuka the winner of the development contest.

Honing the design

Despite being chosen, the design was still lacking and drew frequent criticism from Wolfram von Richthofen. Testing of the V4 prototype (A Ju 87 A-0) in early 1937 revealed several problems. The Ju 87 could take off in just 250 m (820 ft) and climb to 1,875 m (6,150 ft) in just eight minutes with a 250 kg (550 lb) bomb load, and its cruising speed was 250 km/h (160 mph). However, Richthofen pushed for a more powerful engine.

 had a better acceleration rate, and could climb away from the target area much more quickly, avoiding enemy ground and air defenses. Richthofen stated that any maximum speed below 350 km/h (217 mph) was unacceptable for those reasons. Pilots also complained that navigation and powerplant instruments were mixed together, and were not easy to read, especially in combat. Despite this, pilots praised the aircraft's handling qualities and strong airframe.

These problems were to be resolved by installing the Daimler-Benz DB 600

 engine, but delays in development forced the installation of the Jumo 210 Da in-line engine. Flight testing began on 14 August 1936. Subsequent testing and progress fell short of Richthofen's hopes, although the machine's speed was increased to 280 km/h (173 mph) at ground level and 290 km/h (179 mph) at 1,250 m (4,100 ft), while maintaining its good handling ability.

 parts wherever possible, preferring moulded and cast parts instead. Large airframe segments were interchangeable as a complete unit, which increased speed of repair.
The airframe was also subdivided into sections to allow transport by road or rail. The wings were of standard Junkers double-wing construction. This gave the Ju 87 considerable advantage on take-off; even at a shallow angle, large lift forces were created through the aerofoil, reducing take-off and landing runs.

In accordance with the Aircraft Certification Center for "Stress Group 5", the Ju 87 had reached the acceptable structural strength requirements for a dive bomber. It was able to withstand diving speeds of 600 km/h (373 mph) and a maximum level speed of 340 km/h (211 mph) near ground level, and a flying weight of 4,300 kg (9,480 lb). Performance in the diving attack was enhanced by the introduction of dive brakes under each wing, which allowed the Ju 87 to maintain a constant speed and allow the pilot to steady his aim. It also prevented the crew from suffering extreme g forces

The powerplant was cooled by a 10 L (3 US gal) ring-shaped aluminium

 water container situated between the propeller and engine. A further container of 20 L (5 US gal) was positioned under the engine.
The control surfaces operated in much the same way as other aircraft, with the exception of the innovative automatic pull-out system. Releasing the bomb initiated the pull-out, or automatic recovery and climb, upon the deflection of the dive brakes. The pilot could override the system by exerting significant force on the control column and taking manual control.

The wing was the most unusual feature. It consisted of a single center section and two outer sections installed using four universal joints. The center section had a large negative dihedral (anhedral) and the outer surfaces a positive dihedral. This created the gull, or "cranked", wing pattern along the Ju 87's leading edge

 system from the pilot's control column. The rear gunner/radio operator operated one 7.92 mm (.312 in) MG 15 machine gun for defensive purposes.

The engine and propeller had automatic controls, and an auto-trimmer made the aircraft tail-heavy as the pilot rolled over into his dive, lining up red lines at 60°, 75° or 80° on the cockpit side window with the horizon and aiming at the target with the sight of the fixed gun. The heavy bomb was swung down clear of the propeller on crutches prior to release.

Diving procedure

Flying at 4,600 m (15,000 ft), the pilot located his target through a bombsight window in the cockpit floor. The pilot moved the dive lever to the rear, limiting the "throw" of the control column. The dive brakes were activated automatically, the pilot set the trim tabs, retarded his throttle and closed the coolant flaps. The aircraft then rolled 180°, automatically nosing the aircraft into a dive.

, the automatic dive recovery system would be activated. The Stuka dived at a 60-90° angle, holding a constant speed of 500–600 km/h (350-370 mph) due to dive-brake deployment, which increased the accuracy of the Ju 87's aim.

 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 coolant flaps had to be reopened quickly to prevent overheating.

Physical stress on the crew was severe. Human beings subjected to more than 5 g forces in a seated position will suffer vision impairment in the form of a grey veil known to Stuka pilots as "seeing stars". They lose vision while remaining conscious; after five seconds, they black out. The Ju 87 pilots experienced the visual impairments most during "pull-up" from a dive.

I had a high opinion of the Stuka because I had flown a lot of dive-bombers and it’s the only one that you can dive truly vertically. Sometimes with the dive-bombers, pilots claim that they did a vertical dive. What a load of rubbish. The maximum dive is usually in the order of 60 degrees.

 plant. It was discovered that the highest load a pilot could endure was 8.5 g for three seconds, when the aircraft was pushed to its limit by the centrifugal forces. At less than 4 g, no visual problems or loss of consciousness were experienced. Above 6 g, 50% of pilots suffered visual problems, or "grey" out. With 40%, vision vanished altogether from 7.5 g upwards and black-out sometimes occurred. Despite this blindness, the pilot could maintain consciousness and was capable of "bodily reactions". However, after more than three seconds, half the subjects passed out. The pilot would regain consciousness two or three seconds after the centrifugal forces had dropped below 3 g and had lasted no longer than three seconds. In a crouched position, pilots could withstand 7.5 g and were able to remain functional for a short duration. In this position, Junkers concluded that ⅔ of pilots could withstand 8 g and perhaps 9 g for three to five seconds without vision defects which, under war conditions, was acceptable.
During tests with the Ju 87 A-2, new technologies were tried out to reduce the effects of g forces. The pressurised cabin was of great importance during this research. Testing revealed that at high altitude, even 2 g could cause death in an unpressurised cabin and without appropriate clothing. This new technology, along with special clothing and oxygen masks, was researched and tested. When the United States Army

 strategic bomber was initially supposed to have dive bombing capabilities, a requirement that contributed to the failure of the design.

Once the Stuka became too vulnerable to fighter opposition on all fronts, work was done to develop a replacement. None of the dedicated close-support designs on the drawing board progressed far due to the impact of the war and technological difficulties. So the Luftwaffe settled on the Focke-Wulf Fw 190

 sections had smooth leading and trailing edges. The pilot could adjust the elevator and rudder trim tabs in flight, and the tail was connected to the landing flaps, which were positioned in two parts between the ailerons and fuselage. The A-0 also had a flatter engine cowling, which gave the pilot a much better field of vision. In order for the engine cowling to be flattened, the engine was set down nearly .25 m (10 in). The fuselage was also lowered along with the gunner's position, allowing the gunner a better field of fire.

The RLM ordered seven A-0s initially, but then increased the order to 11. Early in 1937, the A-0 was tested with varied bomb loads. The underpowered Jumo 210 A, as pointed out by von Richthofen, was insufficient, and was quickly replaced with the Jumo 210 D power plant.

The A-1 differed from the A-0 only slightly. As well as the installation of the Jumo 210 D, the A-1 had two 220 L (60 US gal) fuel tanks built into the inner wing, but it was not armoured or protected. The A-1 was also intended to be fitted with two 7.92 mm (.312 in) MG 17 machine guns in each wing, but this was dropped due to excessive weight. The two that remained were fed a total of 500 rounds of ammunition, stored in the undercarriage "spats". The pilot relied on the Revi C 21C gun sight for the two MG 17s. The gunner had only a single 7.92 mm (.312 ) MG 15, with 14 drums of ammunition, each containing 75 rounds. This represented a 150-round increase in this area over the Ju 87 A-0. The A-1 was also fitted with a larger 3.3 m (10.8 ft) propeller.

The Ju 87 was capable of carrying a 500 kg (1,100 lb) bomb, but only if not carrying the rear gunner/radio operator as, even with the Jumo 210 D power plant, the Ju 87 was still underpowered for operations with more than a 250 kg (550 lb) bomb load. All Ju 87 As were restricted to 250 kg (550 lb) weapons (although during the Spanish Civil War

Ju 87 B

The Ju 87 B series was to be the first mass-produced variant. The first variant, the Ju 87 B-0, was produced in small numbers. A total of six Ju 87 B-0s were produced, built from Ju 87 A airframes. Test flights began from the summer of 1937. A small number, at least three, served as conversion Cs or Es for potential naval variants. Most of the prototypes were conversions from the Ju 87 A-1.

The next major variant was the Ju 87 B-1, with a considerably larger engine, its Junkers Jumo 211

s with a diameter of 0.7 m (2.3 ft) mounted on the wing's leading edge directly forward of the landing gear, or on the front edge of the fixed main gear fairing. This was used to weaken enemy morale and enhance the intimidation of dive-bombing. After the enemy became used to it, however, they were withdrawn. The devices caused a loss of some 20–25 km/h (10-20 mph) through drag. Instead, some bombs were fitted with whistles on the fin to produce the noise after release.

 by July 1937. Production would be carried out by the Weserflug company after April 1938, but another 352 Ju 87 B-1s were built at Junkers up until March 1940. From August 1938 to March 1940, the Weserflug company produced 740 Ju 87s. In total, an estimated 700 Ju 87 B-1s and 230 B-2s were delivered to the Luftwaffe, of which 550 were built at Junkers. The remaining machines were built at Weserflug's Bremen factory.

A long range version of the Ju 87 B was also built, known as the Ju 87 R. They were primarily intended for anti-shipping missions. Internal fuel capacity was increased by adding two inner-wing 240 L (60 US gal) fuel tanks and by using two standardised Luftwaffe 300 L (80 US gal) capacity under-wing drop tanks. This increased capacity to 1,080 litres. Bomb carrying ability was reduced to a single 250 kg (550 lb) bomb if the aircraft was fully loaded with fuel.

The naval variant of the Ju 87 B was known as the Ju 87 C. These were built to operate from the aircraft carrier Graf Zeppelin

. The carrier was never completed, and all of the aircraft were converted back to the Ju 87 B standard. The Ju 87 R-1 had a B-1 airframe with the exception of a modification in the fuselage which enabled an additional oil tank. This was installed to feed the engine due to the increase in range after the addition of the extra fuel tanks.

The Ju 87 R-2 had the same airframe as the B-2, and strengthened to ensure it could withstand dives of 600 km/h (370 mph). The Jumo 211D in-line engine was installed, replacing the R-1s Jumo 211A. Due to an increase in overall weight by some 700 kg (1,540 lb), the Ju 87 R-2 was 30 km/h (20 mph) slower than the Ju 87 B-1 and had a lower service ceiling. The Ju 87 R-2 had an increased range advantage of 360 km (220 mi). The R-3 and R-4 were the last R variants developed. Only a few were built. The R-3 was an experimental tug for gliders and had an expanded radio system so the crew could communicate with the glider crew by way of the tow rope. The R-4 differed from the R-2 in the Jumo 211J powerplant. Like the R-3, it was produced only in limited numbers.

The Weserflug works at Bremen built 471 Ju 87 R-2s and 145 Ju 87 R-4s. 143 R-4s were delivered, while two were destroyed on test flights.
The tropicalised versions were initially named the Ju 87 B-2/U1. This was eventually designated the Ju 87 B-2 trop, equipped with tropical emergency equipment and sand filters for the powerplant.

. The type was ordered into prototype production and available for testing in January 1938. Testing was given just two months and was to begin in February and end in April 1938. The prototype V10 was to be a fixed wing test aircraft, while the following V11 would be modified with folding wing

s. The prototypes were Ju 87 B-0 airframes powered by Jumo 211 A aero engines. Owing to delays, the V10 was not completed until March 1938. It first flew on 17 March and was designated Ju 87 C-1. On 12 May, the V11 also flew for the first time. By 15 December 1939, 915 arrested landings on dry land had been made. It was found the arresting gear

 winch was too weak and had to be replaced. Tests showed the average braking distance was 20–35 metres (65-115 feet).
The Ju 87 V11 was designated C-0 on 8 October 1938. It was fitted out with standard Ju 87 C-0 equipment and better wing-folding mechanisms. The "carrier Stuka" was to be built at the Weserflug Company's Bremen plant between April and July 1940. Between July 1940 and August 1941, 120 Ju 87 C-1s were built.

Among the "special" equipment of the Ju 87 C was a two-seat rubber dinghy

 with signal ammunition and emergency ammunition. A quick fuel dump mechanism and two inflatable 750 L (200 US gal) bags in each wing and a further two 500 L (130 US gal) bags in the fuselage enabled the Ju 87 C to remain afloat for up to three days in calm seas.
On 6 October 1939, with the war already underway, 120 of the planned Ju 87 Tr(C)s on order at that point were cancelled. Despite the cancellation, the tests continued using catapults. The Ju 87 C had a takeoff weight of 5,300 kg (11,700 lb) and a speed of 133 km/h (82 mph) on departure. The Ju 87 could be launched with a SC 500 kg (1,100 lb) bomb and four SC 50 kg (110 lb) bombs under the fuselage. The C-1 was to have two MG 17s mounted in the wing with a MG 15 operated by the rear gunner. On 18 May 1940, production of the C-1 was switched to the R-1. The fleet of existing Ju 87 Cs were lost during the war.

 with an extremely high rate of fire was installed in the rear defensive position. Engine power was increased again, the Jumo 211 J-1 or Jumo 211P now delivering 1,420 PS (1,044 kW, 1,401 hp).

The fuel capacity of the Ju 87 D was also raised to 1,370 L (360 US gal). Tests at Rechlin 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. Production of the D-1 variant started in 1941 with 495 ordered. These aircraft were delivered between May 1941 and March 1942. The RLM wanted 832 machines produced from February 1941. The Weserflug company was tasked with their production. From June to September 1941, 40 Ju 87 Ds were expected to be built, increasing to 90 thereafter. Various production problems were encountered. Just one of the planned 48 was produced in July. Of the 25 the RLM hoped for in August 1941, none were delivered. Only in September 1941 did the first two of the planned 102 Ju 87s roll off the production lines. The shortfalls continued to the end of 1941. During this time, the WFG plant in Bremen moved production to Berlin. Over 165 Ju 87s had not been delivered and production was only 23 Ju 87 Ds per month out of the 40 expected. By the spring of 1942 to the end of production in 1944, 3,300 Ju 87s, mostly D-1s, D-2s and D-5s had been manufactured. The D-series saw extensive use in the Eastern Front

The Eastern Front of World War II was a theatre of World War II between the European Axis powers and co-belligerent Finland against the Soviet Union, Poland, and some other Allies which encompassed Northern, Southern and Eastern Europe from 22 June 1941 to 9 May 1945...

 and North Africa. Bomb carrying ability was massively increased from 500 kg (1,100 lb) in the B-version to 1,800 kg (3,970 lb) in the D-version (max. load for short ranges, overload condition), a typical bomb load ranged from 500-1,200 kg (1,100-2,650 lb).

The D-2 was a variant used as a glider tug by converting older D-series airframes. It was intended as the tropical version of the D-1. It was to have heavier armour to protect the crew from ground fire. The armour 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 armour for its ground-attack role. The D-3 was converted from D-2 status and equipped with the Jumo 211 J. A number of Ju 87 Ds were designated D-3Ns or D-3/ trops and fitted with night and tropical equipment. The D-4 designation applied to a prototype torpedo-bomber version, which could carry a 750–905 kg (1,650-2,000 lb) aerial torpedo

 on a PVC 1006 B rack. The D-4 was to be converted from D-3 airframes and 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.

The Ju 87 D-5 was based on the D-3 design and was unique in the Ju 87 series as it had wings 0.6 metres (1 foot) longer than previous variants. The powerplant was upgraded to the Jumo 211 P in-line engine with supercharger intercoolers. In August 1943, this was replaced with the Jumo 211 J-1. This engine increased the rate of climb by 15 m/s (2,953 ft/min). With introduction of the Jumo 213 and increased power and climb rate, the lengthened wings were no longer needed. The window in the floor of the cockpit was reinforced and four, rather than the previous three, aileron hinges were installed. Higher diving speeds were obtained of 650 km/h (408 mph) up to 2,000 m (6,560 ft). The range was recorded as 715 km (443 mi) at ground level and 835 km (517 mi) at 5,000 m (16,400 ft).

Fuel capacity was in the form of one main 480 L (127 US gal) fuselage tank and two wing tanks of 150 L (40 US gal) capacity. Two 300 L (80 US gal) drop tanks could also be installed under the wings. The D-5 was also fitted with a 20 mm MG 151/20 cannon in each wing. Both magazines had a capacity of 180 rounds. The radio operator/gunner operated 7.92 mm (.312 in) MG 81Z. Ammunition loads usually ranged from 1,400 to 2,000 rounds.
The D-6, according to "Operating instructions, works document 2097", was built in limited numbers to train pilots on "rationalised versions". However, due to shortages in raw materials, it did not go into mass production.
The D-7 was another ground attack aircraft based on D-1 airframes upgraded to D-5 standard (armor, wing cannons, extended wing panels), while the D-8 was similar to the D-7 but based on D-3 airframes. The D-7 and D-8 were both were fitted with flame dampers, and could conduct night operations.

The Ju 87 E and F proposals were never built, and Junkers went straight onto the next variant. Another variant derived from the Ju 87 D airframe, the Ju 87 H saw service as a dual-control trainer.

In January 1943, a variety of Ju 87 Ds became "test beds" for the Ju 87 G variants. At the start of 1943, the Luftwaffe test centre at Tarnewitz tested this combination from a static position. Oberst G. Wolfgang Vorwald noted the experiments were not successful, and suggested the cannon be installed on the Messerschmitt Me 410

 near the Briansk training area. Stepp noted the increase in drag, which reduced the aircraft's speed to 259 km/h (162 mph). Stepp also noted that the aircraft was also less agile than the existing D variants. D-1 and D-3 variants operated in combat with the 37 mm (1.46 in) BK 37 cannon in 1943.

The G-1 was converted from older D-series airframes, 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 airframes.

In June 1943, the RLM ordered 20 Ju 87 Gs as production variants. The G-1 later influenced the design of the A-10 Thunderbolt II, with Hans Rudel's book, Stuka Pilot being required reading for all members of the A-X project.

s at night to drop flares and fragmentation bombs, inspired the Luftwaffe to form its own Störkampfstaffeln (harassment squadrons). On 23 July 1942, Junkers offered the Ju 87 B-2, R-2 and R-4s with Flammenvernichter ("flame eliminators"). On 10 November 1943, the RLM GL/C-E2 Division finally authorised the design in directive No. 1117. This new equipment made the Ju 87 more difficult to detect from the ground in darkness.

Pilots were also asked to complete the new "Blind Flying Certificate 3", which was especially introduced for this new type of operation. Pilots were trained at night, over unfamiliar terrain, and forced to rely on their instruments for direction. The Ju 87's standard Revi C12D gunsight was replaced with the new Nachtrevi ("Nightrevi") C12N. On some Ju 87s, the Revi 16D was exchanged for the Nachtrevi 16D. To help the pilot see his instrument panel, a violet light was installed.

In the first half of 1943, 12 Nachtschlachtgruppen had been formed, flying a multitude of different types of aircraft, including the Ju 87, which proved itself ideally suited to the low-level slow flying needed.

Production

Despite teething problems with the Ju 87, the RLM ordered 216 Ju 87 A-1s into production and wanted to receive delivery of all machines between January 1936 and 1938. The Junkers production capacity was fully occupied and licensing to other production facilities became necessary. The first 35 Ju 87 A-1s were therefore produced by the Weserflug Aircraft Company Limited (WFG). By 1 September 1939, 360 Ju 87 As and Bs had been built by the Junkers factories at Dessau and Weserflug factory in Bremen. By 30 September 1939, Junkers had received 2,365,196 Reichsmark

 records in Berlin, by the end of the financial year on 30 September 1941, 3,059,000 RM had been spent on Ju 87 airframes. By 30 June 1940, 697 Ju 87 B-1s and 129 B-2s alone had been produced. Another 105 R-1s and seven R-2s had been built.

The range of the B-2 was not sufficient, and it was dropped in favour of the Ju 87 R long-range versions in the second half of 1940. The 105 R-1s were converted to R-2 status and a further 616 production R-2s were ordered. In May 1941, the development of the D-1 was planned. It was ordered into production by March 1942.

 production meant this did not take place. The Weserflug plant in Bremen experienced production shortfalls. This prompted Erhard Milch to visit and threaten the company into meeting the RLM's Ju 87 D-1 requirements on 23 February 1942. To meet these demands, 700 skilled workers were needed. Skilled workers had been called up for military service in the Wehrmacht

. Junkers were able to supply 300 German workers to the Weserflug factory, and as an interim solution, Soviet prisoners of war and Soviet civilians deported to Germany. Working around the clock, the shortfall was made good. WFG received an official commendation. By May 1942, demand increased further. Chief of Procurement General Walter Herthel found that each unit needed 100 Ju 87s as standard strength and an average of 20 per month to cover attrition. Not until June–December 1942 did production capacity increase, and 80 Ju 87s were produced per month.

By 17 August 1942, production had climbed rapidly after Blohm & Voss BV 138 production was scaled down and licence work had shut down at WFG. Production now reached some 150 Ju 87 D airframes per month, but spare parts were failing to reach the same production levels. Undercarriage parts were particularly in short supply. Milch ordered production to 350 Ju 87s per month in September 1942. This was not achievable due to the insufficient production capacity in the Reich.

The RLM considered setting up production facilities in Slovakia

. But this would delay production until the buildings and factories could be furnished with the machine tools. These tools were also in short supply, and the RLM hoped to purchase them from Switzerland and Italy. The Slovaks could provide 3,500–4,000 workers, but no technical personnel. The move would only produce another 25 machines per month at a time when demand was increasing. In October, production plans were dealt another blow when one of WFGs plants burned down, leaving a chronic shortage of tailwheels and undercarriage parts. Junkers director and member of the Luftwaffe industry council Carl Frytag reported that by January 1943 only 120 Ju 87s could be produced at Bremen and 230 at Berlin-Tempelhof

, a fighter pilot with operational and combat experience in strike aircraft, said that abandoning development would be premature, but 150 machines per month would be sufficient.
On 28 July 1943, strike and bomber production was to be scaled down, and fighter and bomber destroyer production given priority. On 3 August 1943, Milch contradicted this and declared that this increase in fighter production would not affect production of the Ju 87, Ju 188, Ju 288 and Ju 290. This was an important consideration as the life expectancy of a Ju 87 had been reduced (since 1941) from 9.5 months to 5.5 months to just 100 operational flying hours. On 26 October, General der Schlachtflieger Ernst Kupfer reported the Ju 87 could no longer survive in operations and that the Focke-Wulf Fw 190F should take its place. Milch finally agreed and ordered the minimal continuance of Ju 87 D-3 and D-5 production for a smooth transition period.
In May 1944, production wound down. 78 Ju 87s were built in May and 69 rebuilt from damaged machines. In the next six months, 438 Ju 87 Ds and Gs were added to the Ju 87 force as new or repaired aircraft. It is unknown whether any Ju 87s were built from parts unofficially after December 1944 and the end of production.

Overall, some 550 Ju 87 As and B2s were completed at the Junkers factory in Dessau. Production of the Ju 87 R and D variants were transferred to the Weserflug company, which was to produce 5,930 of the 6,500 Ju 87s produced in total. During the course of the war, little damage was done to the WFG plant at Bremen. Attacks throughout 1940-45 caused little lasting damage and succeeded only in damaging some Ju 87 airframes, in "contrast" to the Focke-Wulf plant in Bremen. At Berlin-Templehof, little delay and damage was caused to Ju 87 production, despite the heavy bombings and large-scale destruction inflicted on other targets. The WFG again went unscathed. The Junkers factory at Dessau was heavily attacked, but not until Ju 87 production had ceased. The Ju 87 repair facility at the Wels

The experience of the Spanish Civil War proved invaluable - air and ground crews perfected their skills, and equipment was evaluated under combat conditions. Although no Ju 87s had been lost in Spain, however, the Ju 87 had not been tested against numerous and well-coordinated fighter opposition, and this lesson was to be learned later at great cost to the Stuka crews.

The Battle of Britain proved for the first time that the Junkers Ju 87 was vulnerable in hostile skies against well-organised and determined fighter opposition. The Ju 87, like other dive bombers, was slow and possessed inadequate defences. Furthermore, it could not be effectively protected by fighters because of its low speed, and the very low altitudes at which it ended its dive bomb attacks. The Stuka depended on air superiority, the very thing being contested over Britain. It was withdrawn from attacks on Britain in August after prohibitive losses, leaving the Luftwaffe without precision ground-attack aircraft.

Steady losses had occurred throughout their participation in the battle. On 18 August, known as the Hardest Day

 because both sides suffered heavy losses, the Stuka was withdrawn after 16 were destroyed and many others damaged. According to the Generalquartiermeister der Luftwaffe, 59 Stukas had been destroyed and 33 damaged to varying degrees in six weeks of operations. Over 20% of the total Stuka strength had been lost between 8 August and 18 August; and the myth of the Stuka shattered. The Ju 87s did succeed in sinking six warships, 14 merchant ships, badly damaging seven airfields and three radar stations, and destroying 49 British aircraft, mainly on the ground.

, closer to the area of the proposed invasion of Britain. On 13 September, the Luftwaffe targeted airfields again, with a small number of Ju 87s crossing the coast at Selsey and heading for Tangmere.
After a lull, anti-shipping operations attacks were resumed by some Ju 87 units from 1 November 1940, as part of the new winter tactic of enforcing a blockade. Over the next 10 days, seven merchant ships were sunk or damaged, mainly in the Thames Estuary, for the loss of four Ju 87s. On 14 November, 19 Stukas from III./St.G 1 with escort drawn from JG 26 and JG 51 went out against another convoy; as no targets were found over the estuary, the Stukas proceeded to attack Dover, their alternate target.

By 1943, the Allies enjoyed air supremacy in North Africa. The Ju 87s ventured out in Rotte strength only, often jettisoning their bombs at the first sight of enemy aircraft. Adding to this trouble, the German fighters had only enough fuel to cover the Ju 87s on take off, their most vulnerable point. After that, the Stukas were on their own.

After picking their way through the wreckage across the front, Luftwaffe officers found that the tally exceeded 2,000. In the next two days, the Soviets reported the loss of another 1,922 aircraft. Soviet aerial resistance continued but ceased to be effective and the Luftwaffe maintained air superiority until the end of the year.

, 1,208 Stuka sorties were flown against this small strip of land. The intense air attack, though causing horrific losses on Soviet units, failed to destroy them. The Luftwaffe's Sturzkampfgeschwader made a maximum effort during this phase of the war. They flew an average of 500 sorties per day and caused heavy losses among Soviet forces, losing an average of only one Stuka per day.

The Battle of Stalingrad marked the high point in the fortunes of the Junkers Ju 87 Stuka. As the strength of the Soviet Air Forces grew, they gradually wrested control of the skies from the Luftwaffe. From this point onward, Stuka losses increased.

 holders. StG 77 lost 24 Ju 87s in the period 5–31 July (StG had lost 23 in July–December 1942), while StG 2 lost another 30 aircraft in the same period. In September 1943, three of the Stuka units were re-equipped with the Fw 190F and G (ground attack versions) and began to be re-named as Schlachtgeschwader (attack wings). In the face of overwhelming air opposition, the dive-bomber required heavy protection from German fighters to counter Soviet fighters. Some units like SG 2 Immelmann continued to operate with great success throughout 1943-45, operating the Ju 87 G variants equipped with 37 mm cannons, which became tank killers, although in increasingly small numbers.

In the wake of the defeat at Kursk, Ju 87s played a vital defensive role on the southern wing of the Eastern Front. To combat the Luftwaffe, the Soviets could deploy some 3,000 fighter aircraft. As a result, the Stukas suffered heavily. SG 77 lost 30 Ju 87s in August 1943 as did SG 2 Immelmann, which also reported the loss of 30 aircraft in combat operations.

 also included substantial use of the Ju 87 units, although again, unsuccessful in stemming the advances. Stuka units were with the loss of air superiority, becoming vulnerable on the ground as well. Some Stuka aces were lost this way. In the aftermath of Kursk, Stuka strength fell to 184 aircraft in total. This was well below 50 percent of the required strength. On 18 October 1943, StG 1, 2, 3, 5 and 77 were renamed Schlachtgeschwader (abbreviated as "SG") wings, reflecting their ground-attack role, as these combat wings were now also using ground-attack aircraft, such as the Fw 190F-series aircraft. The Luftwaffe's dive-bomber units had ceased to exist.
Operation Bagration to Berlin 1944–1945

Towards the end of the war, as the Allies gained air supremacy, the Stuka was being replaced by ground-attack versions of the Fw 190. By early 1944, the number of Ju 87 units and operational aircraft terminally declined. For the Soviet summer offensive, Operation Bagration, 12 Ju 87 Gruppen and five mixed Gruppen (including Fw 190s) were on the Luftwaffe's order of battle on 26 June 1944.Gefechtsverband Kuhlmey, a mixed aircraft unit, which included large numbers of Stuka dive bombers, was rushed to the Finnish front in the summer of 1944 and was instrumental in halting the Soviet fourth strategic offensive

. The unit claimed 200 Soviet tanks and 150 Soviet aircraft destroyed for 41 losses. By this juncture, the Luftwaffe continued to resist Soviet air attacks but it had little impact on the ground war.

By 31 January 1945, only 104 Ju 87s remained operational with their units. The other mixed Schlacht units contained a further 70 Ju 87s and Fw 190s between them. Chronic fuel shortages kept the Stukas grounded and sorties decreased until the end of the war in May 1945.
