The Panther II is a German tank design of the Second World War based on the design of the original Panther tank. It had slightly thicker armour than the Panther and adopted some standardised components from the Tiger II tank design.[1][a] The Panther II did not progress beyond prototypes and did not enter production.

Development and production

[edit]

The early motivation for improving the Panther tank came from the concern of Adolf Hitler and others who believed that it lacked sufficient armour. Hitler had already insisted on an increase in its armour once, early in the design of the original Panther in 1942. Discussions involving Hitler in January 1943 called for further increased armour; initially referred to as Panther 2, it was known as the Panther II after April 1943. Following the decision not to commence production, the concepts and ideas were used for the design of the E-50 Standardpanzer project.

Armour

[edit]

This upgrade to the Panther tank increased the thickness of the glacis plate from 80 mm (3.1 in) to 100 mm (3.9 in), the side hull armour from 40 mm (1.6 in) to 60 mm (2.4 in), and decreased the armour on the top hull from 40 mm (1.6 in) to 30 mm (1.2 in). Production of the Panther II was slated to begin in September 1943. On 10 February 1943, Dr. Wiebecke (chief design engineer for Maschinenfabrik Augsburg-Nürnberg (M.A.N.) suggested thoroughly redesigning the Panther II and incorporating Tiger II components such as the steering gear, final drives, the suspension system and turret based on Eastern Front experience. The total weight would have increased to more than 50 tonnes.[2] Another meeting on 17 February 1943 focused on sharing and standardising parts between the Tiger II and the Panther II, such as the transmission, all-steel 80-centimetre diameter road-wheels that only overlapped (as on the Tiger II) and not interleaved (as the original 'Schachtellaufwerk' road-wheel system used) and running gear.

Turret

[edit]

The Panther II was to be fitted with a new turret, the Turm Panther 2 (German "schmale Blendenausführung" for "narrow aperture variant").[3] For a long time, it was assumed that the Schmalturm was designed for the Panther II, but it was designed after the Panther II had been cancelled and was intended for the Panther Ausf. F.[4]

Engine

[edit]

A number of engines were under consideration, among them the new Maybach HL234 fuel-injection engine (900 hp operated by an 8-speed hydraulic[citation needed] transmission) and the BMW 003 aviation turbojet-derived, GT 101 turboshaft powerplant, planned to be of 1,150 shaft horsepower output and weighing only 450 kg (992 lb) without its transmission, only 38% of the weight of the Panther's standard Maybach HL230 V-12 gasoline fueled piston engine. The engine would have given the Panther II an increased 200 hp, which would have made it faster than its predecessor, though it was heavier.[5] Plans to replace the original Panther design with the Panther II were already underway before the first Panther had even seen combat. But from May to June 1943 a final meeting was held at M.A.N where it was decided that production of the Panther II would cease, and work would focus on the Panther I.[6] It is not clear if there was ever an official cancellation – this may have been because the Panther II upgrade pathway was originally started at Hitler's insistence.

Crew

[edit]

The Panther II required five crew members to operate, its turret accommodated three crew members, the commander, gunner, and loader whilst the driver and radio operator sat in the hull, in an arrangement identical to the Panther I.

Surviving vehicles

The Panther II (German: Panzerkampfwagen V Panther II) was a proposed German variant developed during as an upgraded successor to the Panzer V Panther, aimed at enhancing protection against emerging Soviet anti-tank threats on the Eastern Front. Initiated in early 1943 amid concerns over the original Panther's vulnerability to Russian tank guns and anti-tank rifles, the design sought to standardize components with the , including a new with interleaved steel road wheels, a narrower turret ring (1,565 mm diameter), and significantly thicker armor plating—such as a 100 mm plate, 60 mm hull sides, 120 mm turret front, and 150 mm —resulting in an estimated weight of 47 metric tons. It was planned to retain the 7.5 cm KwK 42 L/70 main gun of the Panther Ausf. G, with potential compatibility issues preventing integration of narrower turrets like the or larger 8.8 cm armaments. Development progressed under MAN's oversight, with production initially scheduled for September 1943 at factories like and , but delays pushed this to late 1944 or early 1945; however, by May 1943, the addition of effective add-on armor (Schürzen skirts) and other modifications to the existing Panther line rendered the Panther II obsolete, leading to the halt of its development and planned production, though one experimental was later completed. Only one experimental chassis was fabricated by , which was fitted post-war with a standard Panther Ausf. G turret for evaluation; this sole surviving example was captured by Allied forces and is preserved at the U.S. Army's National Armor and Cavalry Collection at Fort Moore.

Background and Development

Origins and Requirements

The development of the Panther II was proposed in in response to anticipated vulnerabilities in the original , particularly its insufficient frontal armor against Soviet anti-tank weapons such as 76 mm guns and anti-tank rifles on the Eastern Front. These concerns were formalized in early amid combat reports highlighting the need for enhanced protection to maintain the tank's effectiveness amid escalating pressures. Additionally, the original Panther Ausf. D and Ausf. A models suffered from mechanical issues, including transmission failures and engine overheating, which further catalyzed the push for a redesigned variant. On 3 January 1943, Adolf Hitler approved the conversion of the Panther design into a new model with improved armor—at least 100 mm on the frontal plates and 60 mm on the sides—during a conference with Armaments Minister Albert Speer, to counter emerging Allied threats. This approval formalized the project and led to its designation as the Panther II by April 1943. The directive emphasized rapid upgrades to ensure the tank could withstand intensified anti-tank fire from Soviet and Western forces. To streamline production and enhance logistical efficiency, the Panther II incorporated standardized components from the , such as the interleaved road wheels, ZF-AK 7/200 transmission, and HL 230 engine, with these decisions formalized by February 1943. This integration aimed to reduce manufacturing complexities and parts proliferation across German armored vehicles. Initial weight estimates for the Panther II were approximately 47 metric tons due to the added armor, reflecting the trade-offs in mobility for superior protection. Production was planned to commence in September 1943 without extensive prototyping, though delays and resource constraints later altered these timelines.

Design Evolution

The Panther II's design evolved as a modular upgrade parallel to the Panther Ausf. F, intended to address reliability issues identified in early Panther field trials while facilitating easier upgrades and repairs through component standardization with the . This approach emphasized interchangeability of key elements like suspension units and parts to streamline and across German armored forces. In early 1943, WaPrüf 6 issued initial specifications for the Panther II following negotiations between the ordnance department and manufacturers such as and Henschel, with design work commencing in to incorporate Tiger II-compatible features. A January 22, 1943, report outlined the project as initially nearly identical to contemporaneous Panther designs, focusing on refinements rather than a complete redesign. The was lengthened slightly to optimize and accommodate enhanced components, adopting the Tiger II's system with 7 road wheels per side in an interleaved configuration for improved stability and load handling. Throughout mid-1943, iterative design reviews integrated feedback from ongoing Panther operations, prioritizing modular enhancements for rapid field modifications. Consideration was given to alternative turret configurations, including early prototypes aimed at a lower profile, though these remained conceptual and were not finalized for the Panther II. By November 1, 1943, WaPrüf 6 released revised specifications that further refined the modular framework, solidifying compatibility with elements before development shifted priorities.

Technical Specifications

Armament

The primary armament of the Panther II tank was planned to be the 7.5 cm KwK 42 L/70 high-velocity gun, identical to that fitted on late-model Panther Ausf. G tanks. This Rheinmetall-Borsig design featured a 70-caliber barrel of 5.25 meters and fired a variety of ammunition types, including the PzGr. 39/42 armor-piercing capped ballistic cap (APCBC) round with a of 930 m/s, the Sprgr. 42 high-explosive (HE) round, and the PzGr. 40/42 armor-piercing composite rigid (APCR) round with a of 1,130 m/s. The vehicle was designed to carry 79 rounds of 75 mm ammunition in total stowage, distributed across the turret and hull for a mix of AP, HE, and APCR projectiles to engage armored and soft targets effectively. Using the PzGr. 39/42 APCBC round, the gun could penetrate approximately 149 mm of rolled homogeneous armor (RHA) at 30 degrees obliquity from 1,000 meters, providing strong anti-tank capability against contemporary medium tanks. For secondary armament, the Panther II retained the configuration of the standard Panther, with a single 7.92 mm mounted coaxially to the main gun in the turret and another in the hull front for the . These general-purpose s, each capable of a cyclic rate of 800-900 rounds per minute, were intended primarily for anti-infantry and close-range defense, with the gun fed by linked belts and the hull gun using a flexible mount. Ammunition stowage for the s totaled around 5,100 rounds of 7.92 mm, typically allocated as 450 rounds immediately ready for the weapon and 600 for the hull-mounted gun, supplemented by additional belts stored throughout the fighting compartment. Development efforts explored upgrading the primary armament to the more powerful L/71 gun, as used on the , to enhance long-range penetration against heavy armor. However, engineering assessments determined that integrating this longer-barreled weapon would require a complete turret redesign due to recoil length, trunnion positioning, and internal space constraints, rendering it incompatible with the existing Panther II turret ring without significant delays. These proposals were ultimately abandoned in favor of the proven to expedite production. The gunner employed the TZF 12 for aiming the KwK 42, featuring variable magnification of 2.5× (with a 24-degree ) for and 5× (12-degree ) for precise ranging. This Leitz optical system included stadia lines and range estimation scales calibrated specifically for the 75 mm gun's , enabling effective fire control up to the weapon's maximum effective range of about 1,500 meters against armored targets.

Armor and Protection

The Panther II's armor scheme represented a significant upgrade over the original Panther, prioritizing enhanced frontal protection while managing overall weight increases to maintain mobility. The frontal hull featured a single-piece plate measuring 100 mm thick, inclined at a 55° angle from the vertical, which yielded an effective line-of-sight thickness of approximately 180 mm—substantially thicker than the Panther's 80 mm . This sloped configuration not only increased ballistic resistance but also promoted effects against incoming projectiles. Side and rear hull armor consisted of 60 mm thick vertical plates along the hull sides and 40 mm plates at the rear, providing moderate protection against flanking threats without excessive weight penalties. The turret armor included 120 mm thick frontal armor and a 150 mm , with 60 mm thick sides and rear sections, offering improved all-around defense compared to the Panther's thinner layout. These enhancements drew briefly from component standards to facilitate production interchangeability. To balance the added mass from thicker plates, the upper hull roof was specified at 30 mm thick, while the belly plate measured 25 mm; no spaced armor skirts or applique plates were incorporated in the design plans. Overall, this armor configuration was engineered to withstand hits from the Soviet 85 mm D-5T tank gun and 76 mm ZiS-3 divisional gun at ranges up to 1,000 meters, addressing evolving threats on the Eastern Front and elevating the vehicle's combat weight to 47 metric tons.

Turret Design

The Panther II tank was intended to mount the Turm Panther 2 turret, a redesigned structure developed by as depicted in drawing H-Sk A 86176 dated 7 , featuring a narrow , 120 mm thick frontal armor, 150 mm , and integration of a coaxial machine gun. This turret design aimed for compatibility with components through shared production elements, including a planned wider ring diameter to facilitate interchangeability in . The overall dimensions were constrained to a maximum of 1,570 mm—later refined to 1,565 mm by trimming corners—with the distance from the turret center to the rear wall limited to 1,240 mm and the rear wall angled at 20° to ensure clearance over the engine access hatch. The traverse mechanism employed a hydraulic system powered by an engine takeoff, capable of 360° rotation in approximately 30 seconds, supplemented by a manual backup achieving the same in about 4 minutes. An escape hatch was incorporated on the turret roof to allow the commander rapid egress in emergencies. Inside the turret, the layout positioned the gunner on the right side for sighting and aiming the main 75 mm KwK 42 gun, the loader on the left for handling ammunition, and the commander at the rear with a cupola equipped with seven periscopes for all-around observation. Ammunition storage included racks in the turret bustle for ready rounds and additional stowage in the hull sponsons to support an increased capacity of 79 rounds overall. After the Panther II project's cancellation in mid-1943, the narrow turret concepts evolved into the design, which was repurposed for the Panther Ausf. F to minimize frontal and enhance protection, featuring a 120 mm front plate sloped at 12° while retaining the 1,650 mm ring diameter for compatibility with existing .

Engine and Mobility

The Panther II's baseline powerplant was the HL 230 P 30, a water-cooled V-12 gasoline engine producing 700 horsepower at 3,000 rpm, which was the same unit used in production Panther tanks. Proposed upgrades included the fuel-injected HL 234 variant, rated at 900 horsepower, intended to address reliability issues in the original engine while maintaining compatibility with the chassis. An experimental alternative under consideration was the turboshaft gas turbine engine, delivering 1,150 horsepower at a lightweight of approximately 450 kg, though its integration posed challenges due to size and fuel consumption. The drivetrain featured the ZF AK 7-200 synchromesh gearbox with seven forward gears and one reverse, carried over from the Panther for continuity, but designs incorporated an 8-speed hydraulic transmission to mitigate the frequent failures plaguing the original model's final drives and clutches under heavy loads. This setup aimed to balance power delivery with the increased vehicle mass, targeting improved torque distribution across varied terrains. Mobility performance was projected at a maximum road speed of 45-55 km/h and around 25 km/h off-road, supported by a range of 200 km on roads and 100 km cross-country, reflecting the engine's limits and the tank's 47-metric-ton class. Ground pressure was designed to remain manageable at about 0.90 kg/cm² through the use of 660 mm-wide tracks, distributing weight effectively to prevent excessive bogging in soft soil. The , employing interleaved road wheels akin to the II's configuration, provided superior articulation over uneven ground but demanded extensive maintenance for wheel changes and track adjustments. The added armor plating reduced the to roughly 14-19 hp/ depending on the variant, slightly compromising compared to the standard Panther but preserving adequate maneuverability for its intended role.

Crew Layout

The Panther II tank was designed to accommodate a standard five-man , consisting of the commander, gunner, and loader positioned in the turret, while the driver and occupied the hull. The driver sat in the front-left hull compartment, relying on episcopes mounted in the roof for forward and limited lateral vision during operation. Adjacent to the driver, the was located in the front-right hull position, responsible for operating the FuG 5 high-frequency/short-wave transmitter to maintain communications with other units. The three turret crew members coordinated via an internal system, allowing the to direct the gunner—seated to the right—and the loader to the left, who managed retrieval from ready racks. Ergonomic features included separate pivoting escape hatches for the driver and , providing improved access compared to the combined hatch on later Panther Ausf. G models, which facilitated quicker entry and exit in combat conditions. handling was aided by turret basket arrangements and ready storage, enabling the loader to achieve round insertion times of approximately 8 seconds under optimal conditions, a refinement over earlier designs to enhance firing rates. Additional ventilation systems directed away from crew spaces, mitigating fatigue during prolonged operations. The layout supported minimal retraining for crews familiar with the original Panther, with the commander's cupola offering a 360-degree periscopic view for situational awareness and oversight of the vehicle's systems.

Production and Fate

Prototyping Efforts

The prototyping efforts for the Panther II tank were constrained by wartime resource limitations and evolving design priorities, resulting in only partial physical construction rather than full vehicle assembly. In early 1943, the WaPrüf 6 (Heereswaffenamt's tank inspection office) ordered two trial chassis from Maschinenfabrik Augsburg-Nürnberg (MAN) to test the revised hull design, which incorporated thicker armor and an improved suspension system derived from earlier Panther iterations. By mid-1943, MAN had completed a single steel hull chassis without a turret, serving as the primary prototype to evaluate structural integrity and component integration. No complete Panther II vehicles were ever assembled, and development of additional prototypes was halted before the second ordered chassis reached completion. This sole prototype hull underwent limited testing at MAN's facilities in , focusing on suspension performance and weight distribution under the anticipated 47-ton load, which included simulated turret mass through ballast weights. Trials revealed challenges in integrating the proposed transmission—intended to be compatible with components for standardization—but these were not fully resolved due to the program's suspension. A separate turret mockup was constructed to assess ergonomics and handling, though it remained a non-functional wooden model without integration onto the hull. The completed hull was later captured by U.S. forces in and remains the only surviving artifact of the program.

Cancellation and Reasons

The Panther II project was officially halted in May or , with series production cancelled before any further development of late-war armament concepts could proceed. This decision came shortly after the completion of a single experimental by MAN in , which served as the basis for subsequent evaluations but was not advanced to full prototyping. Armaments Minister Albert Speer played a key role in the termination, prioritizing the expansion of the original Panther Ausf. D, A, and G production lines to address immediate combat requirements. The primary reasons for cancellation included severe resource constraints in steel and skilled labor, intensified by mounting Allied strategic bombing that disrupted industrial output, as well as the recognition that the standard Panther's armor—augmented by effective Schürzen side skirts—provided adequate protection against Soviet anti-tank threats without necessitating a heavier redesign. (Speer's Inside the Third Reich, for general armaments context) Strategically, German leadership shifted focus toward specialized heavy vehicles such as the and dedicated tank destroyers like the series, deeming further medium tank upgrades like the Panther II redundant amid escalating material shortages and logistical burdens from its projected weight of 47 metric tons. On 29 April 1943, resources were explicitly redirected to produce the on the existing Panther chassis, leveraging shared components to streamline without the need for a new platform. In the aftermath, elements of the Panther II design—such as improved suspension and engine mounting concepts—were integrated into ongoing Panther modifications and broader initiatives under Speer's oversight, thereby minimizing wasted effort and preserving engineering expertise for sustained armored vehicle output through 1944.

Legacy and Preservation

Influence on Subsequent Designs

The concepts developed for the Panther II, particularly its enhanced armor and chassis standardization efforts, were directly incorporated into the 1944 E-50 Standardpanzer proposal, which aimed to create a unified medium-heavy tank line to replace both the Panther and series. The E-50 built upon the Panther II's concept with a 120 mm sloped glacis plate for improved frontal protection and featured a modular turret design compatible with multiple armaments, reflecting the emphasis on production efficiency and interchangeability. This inheritance stemmed from the broader Entwicklung (E-series) initiative to streamline German tank manufacturing amid resource shortages. Elements of the Panther II's suspension and powertrain were tested and reused in production vehicles like the tank destroyer (1944–1945), which shared the Panther's and HL 230 P30 engine, with some mobility enhancements tested in relation to later designs like the Panther II, addressing earlier Panther reliability issues. Similarly, lighter components influenced the concept within the E-series, where simplified suspension arms and compact powertrain layouts drew from Panther II prototypes to enable faster production of reconnaissance and support vehicles. These adaptations allowed partial realization of the Panther II's engineering without full-scale tank production. Postwar analyses of the Panther series, including the II variant's designs, underscored German over-engineering pitfalls, such as the interleaved road wheels that complicated field maintenance in muddy or frozen conditions, as detailed in U.S. Army evaluations of captured vehicles. These reports informed developments, including the , by emphasizing simpler suspension systems, reliable powertrains, and balanced armor-mobility trade-offs to avoid the Panther's logistical burdens. The cancellation of the Panther II freed resources for these transitional projects, contributing to more practical designs. Modern simulations of the Panther II's hypothetical 1944 deployment indicate it would have maintained combat superiority over the T-34-85 in direct engagements due to its 75 mm KwK 42 gun's penetration and thicker armor, but remained vulnerable to attacks, mirroring broader WWII trends for unarmored-topped tanks. These assessments highlight its potential as an effective but affirm the strategic limitations of late-war German designs.

Surviving Artifacts

The sole surviving example of the Panther II is an incomplete hull , constructed in August 1943 by Maschinenfabrik Augsburg-Nürnberg () as part of early development efforts. This chassis, bearing the number 120417, was captured by U.S. forces in 1945 and shipped to for postwar evaluation. The prototype hull is currently displayed at the U.S. Army Armor & Cavalry Collection at Fort Benning, Georgia (renamed from Fort Moore in 2023, reverted in 2025), having been transferred there in December 2010 from the Patton Museum at Fort Knox, Kentucky. As of 2025, following the base's renaming back to Fort Benning, the artifact remains on display without reported changes. To enhance its display completeness, it has been fitted with a late-production Panther Ausf. G turret (turret number 210, manufactured in April 1945), though this was not part of the original vehicle. The hull itself lacks an engine, original armament, or running gear but retains key structural features, including its 100 mm frontal glacis plate and side armor sections. During restoration work at the Patton Museum in the 2000s, which included fitting components from a Panther Ausf. G to make it operational, original factory welds and markings were uncovered and preserved. No complete Panther II vehicles survive, and only scattered remnants—such as possible scrap components from prototypes—exist in other collections, including related Panther II parts at the Bovington in the . Postwar wooden mockups of the design were reportedly destroyed, leaving the U.S. example as the primary artifact for study.
