Panzer 5 Panther

[Aliza Pointon]

On27 February 1944 it was redesignated to just PzKpfw Panther, as Hitler ordered that the Roman numeral "V" be deleted.[citation needed] In contemporary English-language reports it is sometimes referred to as the "Mark V".

The Panther was intended to counter the Soviet T-34 medium tank and to replace the Panzer III and Panzer IV. Nevertheless, it served alongside the Panzer IV and the heavier Tiger I until the end of the war. The Panther was a compromise. While having essentially the same Maybach V12 petrol (690 hp) engine as the Tiger I, it had better gun penetration, was lighter and faster, and could traverse rough terrain better than the Tiger I. The trade-off was weaker side armour, which made it vulnerable to flanking fire, and a weaker high explosive shell. The Panther proved to be effective in open country and long-range engagements.[8] Although it had excellent firepower, protection and mobility, its reliability was less impressive.[9] The Panther was far cheaper to produce than the Tiger I. Key elements of the Panther design, such as its armour, transmission, and final drive, were simplifications made to improve production rates and address raw material shortages. Despite this, the overall design has still been described by some as "overengineered".[10][11]

The Panther was rushed into combat at the Battle of Kursk in the summer of 1943 despite numerous unresolved technical problems, leading to high losses due to mechanical failure. Most design flaws were rectified by late 1943 and early 1944, though the bombing of production plants, increasing shortages of high-quality alloys for critical components, shortage of fuel and training space, and the declining quality of crews all impacted the tank's effectiveness. Though officially classified as a medium tank, at 44.8 metric tons the Panther was closer in weight to contemporary foreign heavy tanks. The Panther's weight caused logistical problems, such as an inability to cross certain bridges, otherwise the tank had a very high power-to-weight ratio which made it highly mobile.

The Panther was born out of a project started in 1938 to replace the Panzer III and Panzer IV tanks. The initial requirements of the VK 20 series called for a fully tracked vehicle weighing 20 tonnes and design proposals by Krupp, Daimler Benz and MAN ensued. These designs were abandoned and Krupp dropped out of the competition entirely as the requirements increased to a vehicle weighing 30 tonnes, a direct reaction to the encounters with the Soviet T-34 and KV-1 tanks and against the advice of Wa Prf 6.[Notes 1][12] The T-34 outclassed the existing models of the Panzer III and IV.[13][14] At the insistence of General Heinz Guderian, a special tank commission was created to assess the T-34.[15] Among the features of the Soviet tank considered most significant were the sloping armour, which gave much improved shot deflection and also increased the effective armour thickness against penetration, the wide track, which improved mobility over soft ground, and the 76.2 mm (3 in) gun, which had good armour penetration and fired an effective high-explosive round. Daimler-Benz (DB), which designed the successful Panzer III and StuG III, and Maschinenfabrik Augsburg-Nrnberg AG (MAN) were given the task of designing a new 30- to 35-tonne tank, designated VK 30.02, by April 1942.

The "VK 30.02(DB)" design resembled the T-34 in its hull and turret and was also to be powered by a diesel engine. It was driven from the rear drive sprocket with the turret situated forward. The incorporation of a diesel engine promised increased operational range, reduced flammability and allowed for better use of petroleum reserves. Hitler himself considered a diesel engine imperative for the new tank.[16] DB's proposal used an external leaf spring suspension, in contrast to the MAN proposal of twin torsion bars. Wa Prf 6's opinion was that the leaf spring suspension was a disadvantage and that using torsion bars would allow greater internal hull width. It also opposed the rear drive because of the potential for track fouling. Daimler Benz still preferred the leaf springs over a torsion bar suspension as it resulted in a silhouette about 200 mm (7.9 in) shorter and rendered complex shock absorbers unnecessary. The employment of a rear drive provided additional crew space and also allowed for a better slope on the front hull, which was considered important in preventing penetration by armour-piercing shells.[12]

The two designs were reviewed from January to March 1942. Reichsminister Fritz Todt, and later his replacement Albert Speer, both recommended the DB design to Hitler because of its advantages over the initial MAN design. At the final submission, MAN refined its design, having learned from the DB proposal apparently through a leak by a former employee in the Wa Prf 6, senior engineer Heinrich Ernst Kniepkamp and others.[16] On 5 March 1942, Albert Speer reported that Hitler considered the Daimler-Benz design to be superior to MAN's design.[18] A review by a special commission appointed by Hitler in May 1942 selected the MAN design. Hitler approved this decision after reviewing it overnight. One of the principal reasons given for this decision was that the MAN design used an existing turret designed by Rheinmetall-Borsig, while the DB design would have required a brand new turret and engine to be designed and produced, delaying the commencement of production.[19] This time-saving measure compromised the subsequent development of the design.[20]

Since the Tiger had originally been designed to weigh fifty tons but as a result of Hitler's demands had gone up to fifty seven tons, we decided to develop a new thirty ton tank whose very name, Panther, was to signify greater agility. Though light in weight, its motor was to be the same as the Tiger's, which meant it could develop superior speed. But in the course of a year Hitler once again insisted on clapping so much armour on it, as well as larger guns, that it ultimately reached forty eight tons, the original weight of the Tiger.[21]

A mild steel prototype of the MAN design was produced by September 1942 and, after testing at Kummersdorf, was officially accepted. It was put into immediate production. The start of production was delayed, mainly because of a shortage of specialized machine tools needed for the machining of the hull. Finished tanks were produced in December and suffered from reliability problems as a result. The demand for this tank was so high that the manufacturing was soon expanded beyond MAN to include Daimler-Benz (Berlin-Marienfelde, former DMG plant), Maschinenfabrik Niedersachsen Hanover (MNH, a subsidiary of Eisenwerk Wlfel/Hanomag) and the Tiger I's original designer, Henschel & Sohn in Kassel.

The initial production target was 250 tanks per month at the MAN plant at Nuremberg. This was increased to 600 per month in January 1943. Despite determined efforts, this figure was never reached due to disruption by Allied bombing, and manufacturing and resource bottlenecks. Production in 1943 averaged 148 per month. In 1944, it averaged 315 a month (3,777 having been built that year), peaking with 380 in July and ending around the end of March 1945, with at least 6,000 built in total. Front-line combat strength peaked on 1 September 1944 at 2,304 tanks, but that same month a record number of 692 tanks were reported lost.[4]

According to rough estimates the labour hours in comparison to the Panzer III stood at approximately 1 to 1.25, i.e. four Panther vehicles for every five Panzer III tanks built. Cost (without weaponry) PzKpfwIII RM 96,163; Panther RM 117,100.[22]

The Allies directed bombing at the common chokepoint for both Panther and Tiger production: the Maybach engine plant. This was bombed the night of 27/28 April 1944 and production halted for five months. A second factory had already been planned, the Auto Union Siegmar plant (the former Wanderer car factory), and this came on line in May 1944.[23] The targeting of Panther factories began with a bombing raid on the DB plant on 6 August 1944, and again on the night of 23/24 August. MAN was struck on 10 September, 3 October and 19 October 1944, and then again on 3 January and 20/21 February 1945. MNH was not attacked until 14 and 28 March 1945.[24]

The process of streamlining the production of German armoured fighting vehicles first began after Speer became a Reichsminister in early 1942, and steadily accelerated through to 1944; the production of the Panther tank coincided with this period of increased manufacturing-efficiency. At the beginning of the war, German armoured fighting vehicle manufacturers had employed labour-intensive and costly manufacturing methods unsuitable for the needs of mass production; even with streamlined production methods, Germany never approached the efficiency of Allied manufacturing during World War II.[33]

The weight of the production model was increased to 45 tonnes from the original plans for a 35 tonne tank. Hitler was briefed thoroughly on the comparison between the MAN and DB designs in the report by Guderian's tank commission. Armour protection appeared to be inadequate, while "the motor mounted on the rear appeared to him correct". He agreed that the "decisive factor was the possibility of quickly getting the tank into production". On 15 May 1942, Oberst Fichtner informed MAN that Hitler had decided in favour of the MAN Panther and ordered series production. The upper glacis plate was to be increased from 60 mm (2.4 in) to 80 mm (3.1 in). Hitler demanded that an increase to 100 mm (3.9 in) should be attempted and that at least all vertical surfaces were to be 100 mm (3.9 in); the turret front plate was increased from 80 mm (3.1 in) to 100 mm (3.9 in).[17]

The Panther was rushed into combat before all of its teething problems had been corrected. Reliability was considerably improved over time, and the Panther proved to be a very effective fighting vehicle,[34] but some design flaws, such as its weak final drive units, were never corrected.
