The Gotha Go 244 was a transport aircraft designed and produced by the German aircraft manufacturer Gotha. It was operated by the Luftwaffe during the Second World War. It was the powered version of the Gotha Go 242 military glider transport.

Key Information

While studies into a powered model of the Go 242 had commenced relatively early in the glider's development, one of the major factors in what would become the Go 244 was the German's capturing of a large quantity of Gnome-Rhône 14M radial engines following the fall of France in June 1940. Three prototypes were created by modifying Go 242s; these were fitted with engines such as the BMW 132 and the Shvetsov M-25 A. Despite the unimpressive performance of the Gnome engines, Luftwaffe officials were keen to make use of existing inventory, thus the majority of production standard Go 244s were powered by this engine.

The first Go 244s were delivered to operational units based in Crete, Greece in March 1942; the type would also see action in both North Africa and the Eastern Front. Far fewer Go 244s were constructed in comparison to the Go 242, which officials ultimately decided to focus their production capacity upon instead. Some figures, such as Generalfeldmarschall Erhard Milch, criticised the aircraft as being defective, lacking sufficient range, and operationally limited. A mixture of Junkers Ju 52 or Messerschmitt Me 323 transport aircraft supplemented and eventually replaced the Go 244 in Luftwaffe service.

Development

[edit]

Development of the Go 244 has its origins in the widely used Gotha Go 242 military glider, specifically the Go 242B model.[2][3] Studies for powered versions of the Go 242 had commenced relatively early in the design of the glider; one early proposal involved a modification that would have facilitated the temporary attachment of a single Argus As 10C engine to the nose of the glider, which would have allowed for its recovery back to base after use. This concept was ultimately rejected, the alternative proposal of a permanently powered twin-engined version of the aircraft was taken forward.[4] A key factor in the emergence of the Go 244 had been the fall of France in June 1940. Amongst other effects, Germany gained access to France's aviation industry and its supply chain, which meant that the Luftwaffe suddenly had access to a sizable number of captured Gnome-Rhône 14M radial engines that several officials were keen to make use of.[2][5]

Three Go 242s were modified as prototypes of the powered Go 244, fitted with surplus radial engines. The first prototype, the Go 244 V1 was powered by two 660 hp (490 kW) BMW 132, while the second prototype had 700 hp (520 kW) Gnome-Rhône 14Ms — and the third 750 hp (560 kW) Shvetsov M-25 A engines, with this model of Shvetsov OKB engine design being essentially a Soviet-built Wright Cyclone American-based nine-cylinder radial. Although only the third Gnome-equipped prototype offered adequate engine out performance, the ample stocks of these engines led to it being selected as the basis for the production conversion — usually fitted in counter-rotating pairs in production — although a few more aircraft were fitted with the BMW and Shvetsov engines.[6][2]

In August 1941, the Luftwaffe took delivery of the first Go 244A aircraft for testing.[7] It was the Go 244B that was the principal production model; it featured a wheeled tricycle undercarriage and accommodated fuel and oil within the tail booms.[8]

An initial run of 133 aircraft were produced through the conversion of Go 242Bs.[9][10] A further 41 Go 244s were constructed using new airframes. Officials decided against producing further Go 244s for the assembly lines to revert to Go 242 glider production.[11] One senior Luftwaffe official that had openly criticised the Go 244 was Generalfeldmarschall Erhard Milch, who claimed it to be faulty, lacking sufficient range, and of limited value.[12]

Several proposals and plans were mooted for the further development of the Go 244. One area of interest was the creation of single-engined variants; these would have been powered by either a nose-mounted Argus As 10C or Junkers Jumo 211.[13] During 1944, the company's design team directed their attention towards the Gotha Go 345 transport glider instead.[2]

Operational history

[edit]

During March 1942, the first examples of the Go 244 were delivered to operational units stationed in Crete, Greece.[2] Several aircraft were assigned to transport Geschwader in North Africa, their use in this theatre was limited to only a few months after the Go 244 proved to be vulnerable to Allied fighter aircraft and anti-aircraft fire. The type also saw action against the Soviet Union on the Eastern Front.[14][2] It was used a troop transport and to carry freight.[5] In Luftwaffe service, the Go 244 was replaced by Junkers Ju 52 or Messerschmitt Me 323 aircraft.[13]

Gotha Go 244

View on Grokipedia
from Grokipedia
The Gotha Go 244 was a twin-engined developed by the German manufacturer Waggonfabrik for the during , serving as a powered evolution of the earlier Go 242 assault glider to enable independent operations without towing. Primarily designed for troop transport, paratroop drops, and supply delivery in tactical assault roles, it featured a high-wing configuration with a fixed or semi-retractable tricycle landing gear, accommodation for a crew of two plus up to 23 passengers or equivalent cargo, and defensive armament typically consisting of up to four 7.92 mm or MG 81 machine guns. Powered by two captured French Gnome-Rhône 14M radial engines each delivering 700 horsepower, the had a maximum speed of approximately 290 km/h (180 mph), a range of 600 km (370 mi) with a ferry range of 740 km (460 mi), and a service ceiling of 7,500 m (24,600 ft). Development of the Go 244 began in 1941 as an initiative to address the limitations of the unpowered Go 242, with three prototypes (V1, V2, and V3) modified from glider airframes and tested with various engines including the , Gnome-Rhône 14M, and Shvetsov M-25A before production standardized on the readily available Gnome-Rhône due to French factory captures. Initial production involved converting 133 existing Go 242B gliders, followed by 41 newly built airframes, for a total of 174 units manufactured between 1942 and 1944, though output was limited by resource shortages and the 's vulnerability to enemy fighters. Variants included the B-1 (fixed undercarriage), B-2 (semi-retractable nose gear for improved prop clearance), B-3 (twin cargo doors), B-4 (combined B-2/B-3 features), and B-5 (dual-control trainer), but none progressed beyond small-scale use. Operationally, the Go 244 entered service in March 1942 with units in and , later deploying to and the Eastern Front for resupply missions during campaigns like the Axis advance in the Mediterranean and Eastern Front operations. Its short range, slow speed, and lack of heavy armor made it susceptible to interception, leading to high losses and its phased withdrawal from frontline duties in favor of more robust types like the by mid-1943, though it continued in secondary transport roles until the war's end.

Development and Design

Origins and Requirements

The glider was developed in by the -Waggonfabrik works in , , in response to a Reichsluftfahrtministerium (RLM) requirement for a heavy transport glider to supersede the lighter , addressing the Luftwaffe's need for larger-capacity troop and cargo transport during . The RLM requirement specified a glider with short takeoff and landing (STOL) capabilities, able to be towed by Ju 52 bombers, and suitable for carrying heavy cargo or vehicles in addition to troops. Designed by engineer Albert Kalkert, the Go 242 was intended as a high-wing, twin-boom glider capable of carrying up to 23 troops or equivalent freight, with provisions for defensive armament to support airborne operations. This design emerged amid the Luftwaffe's expanding demands for reliable glider transports following early successes in airborne assaults, such as the invasion of Crete in , which underscored the need for larger-capacity gliders like the Go 242, with 1,528 units produced in A and B variants starting in . The fall of in June 1940 provided the with access to substantial stocks of captured Gnome-Rhône 14M radial engines, which significantly influenced the decision to develop a powered derivative of the Go 242 to overcome the glider's limitations as a one-way towed dependent on towing for recovery. These 700-horsepower engines, originally produced for French , were abundant in German inventories and prompted considerations for motorizing the Go 242 to enable independent operations, including short takeoffs and landings on unprepared fields. The 's specifications for this powered assault glider emphasized retaining the Go 242's efficiency and payload capacity while adding self-propulsion for greater tactical flexibility in contested theaters. Early studies for engine integration began in late 1940, shortly after the Go 242's initial design phase, with Gotha-Waggonfabrik exploring modifications to mount powerplants without compromising the glider's aerodynamic profile or structural integrity. Initial concepts included temporary single-engine attachments, such as an Argus As 10C for ferry flights, but these were rejected in favor of a permanent twin-engine configuration to meet the RLM's demands for robust, powered transport capabilities. As the primary designer and manufacturer, Gotha-Waggonfabrik— a firm with roots in production that had re-entered manufacturing in —leveraged its expertise to adapt the Go 242 , prioritizing the use of captured Gnome-Rhône engines for their availability and compatibility.

Prototyping and Engine Integration

In early 1941, constructed three prototypes of the Go 244 by modifying existing Go 242 glider airframes, extending the twin booms forward to accommodate engine mounts and adding a tricycle for powered operations. These conversions utilized surplus radial engines available to German industry, reflecting the urgent need for a motorized troop transport amid wartime shortages. The prototypes tested different engine configurations to evaluate performance and integration feasibility. The Go 244 V1 featured two 660 hp (492 kW) nine-cylinder radials, while the V2 used two 700 hp (522 kW) Gnome-Rhône 14M fourteen-cylinder radials captured from French stocks; the V3 employed two 750 hp (560 kW) nine-cylinder radials sourced from captured Soviet . Engines were mounted on the nose with tractor propellers, requiring adaptations to the firewall and cowling to fit varying sizes, alongside adjustments to maintain balance during powered flight. The first flights occurred in summer near the Gotha works, revealing initial problems with engine reliability—particularly spare parts shortages for the French Gnome-Rhône units—and difficulties in propeller synchronization. Testing demonstrated the Go 244's basic viability as a powered glider variant but exposed limitations, including excessive vibration, overheating under load, and inadequate single-engine performance, which prompted refinements to engine cowlings and mounting systems. These outcomes led to production approval in August 1941, with the Gnome-Rhône 14M selected for its availability despite ongoing reliability concerns, enabling initial deliveries by March 1942.

Key Design Features

The Gotha Go 244 was configured as a high-wing with twin tail booms supporting the , a derived from the unpowered Go 242 glider to facilitate troop and cargo transport while maintaining aerodynamic efficiency. The central pod housed the crew and , with the overall structure emphasizing simplicity and rapid field assembly to support airborne operations. This layout allowed for a spacious interior without compromising the aircraft's stability during low-speed handling. The featured a tubular framework covered in fabric, providing lightweight strength suitable for rough handling, while the wooden wings were clad in fabric and for durability in glider-like operations. At the rear, clamshell-style hinged doors enabled quick loading and unloading of personnel or equipment, such as a Kübelwagen , accommodating up to 23 fully equipped soldiers or equivalent freight loads of approximately 2,700 kg. The interior was modular, with provisions for bench seating in troop configurations or open space for , allowing reconfiguration between paratroop drops and supply missions. The wings had a span of 24.5 meters and a high aspect ratio optimized for the low-speed lift required in glider-derived designs, contributing to efficient short-field performance. Slotted flaps were incorporated to enhance lift during takeoff and landing, supporting operations on unprepared airstrips. A tricycle landing gear with oleo shock absorbers formed the undercarriage, fixed in early variants or with semi-retractable nose gear in later models, enabling operations on uneven terrain and providing stability for the high-wing configuration; the main wheels were larger in later variants for improved ground handling. This setup, combined with the aircraft's overall rugged build, allowed for short takeoff and landing capabilities essential to assault transport roles. For self-defense, the Go 244 included provisions for four 7.92 mm machine guns, typically one in a dorsal position, two in beam mounts, and one in a ventral position, operated by the crew or embarked troops to counter low-level threats during vulnerable approach phases. Key innovations retained the Go 242's glider heritage, including reinforced towing points that permitted aerial towing by like the despite the addition of engines, offering flexibility in mixed glider-transport fleets. The design's adaptability extended to engine integration without sacrificing the original airframe's payload efficiency, making it a versatile platform for rapid deployment in contested areas.

Production and Variants

Manufacturing Process

Production of the Gotha Go 244 began in early 1942 at the facilities in , with initial deliveries to the in March 1942. By 1943, a total of 174 units had been completed, comprising 133 conversions from surplus Go 242B glider airframes and 41 newly constructed examples. The conversion process primarily involved retrofitting the glider fuselages with captured French Gnome-Rhône 14M radial engines, adding tricycle undercarriage, and reinforcing structural elements to accommodate powered flight, leveraging the modular design of the original glider for efficient adaptation. Manufacturing relied heavily on the Gothaer Waggonfabrik's workforce, which included forced laborers amid severe wartime material shortages that affected overall German aviation output. Production rates were constrained by supply disruptions and Allied bombing campaigns targeting aircraft facilities, including the Gotha works. The dependence on captured French engines created significant supply chain vulnerabilities; after initial stocks from the 1940 fall of France were depleted in 1942, shortages necessitated adjustments to variants using alternative powerplants. Production halted in mid-1943 as resources were redirected to unpowered Go 242 gliders and larger powered transports such as the Messerschmitt Me 323, reflecting shifting Luftwaffe priorities toward higher-capacity assault aircraft.

Variant Descriptions

The Gotha Go 244 series encompassed several variants derived from the baseline Go 242 glider design, with modifications primarily focused on engine integration, undercarriage, and specialized roles to enhance its utility as a troop transport aircraft during World War II. These variants were developed to address operational needs in various theaters, though production was limited due to resource constraints and the aircraft's vulnerability to enemy fighters. Conversions from existing Go 242 airframes formed the bulk of the output, totaling approximately 133 units across the B-series models. Go 244 A-1 served as the initial prototype, featuring two radial engines each producing 660 horsepower, and was employed exclusively for testing purposes without entering production. This single airframe allowed engineers to evaluate the feasibility of powering the glider design, confirming the structural adaptations needed for engine mounting on the wing leading edges. No operational use followed its trials, as subsequent models shifted to more available powerplants. Go 244 B-1 represented the standard production model, powered by two Gnome-Rhône 14M-06 radial engines delivering 700 horsepower each, and incorporated a fixed wheeled undercarriage for improved ground handling over the glider's skids. Designed for full troop transport duties, it could accommodate up to 13 fully equipped troops or equivalent cargo (such as 24 stretchers with medical personnel or 3,500 kg of supplies), with over 100 units built or converted to support supply missions in contested areas. Defensive armament typically included machine guns at key positions, though its slow speed limited combat effectiveness. Go 244 B-2 was a revised production model featuring a semi-retractable gear for improved clearance and ground handling, based on the Go 242 A-2 glider. It retained the B-1's engine and troop capacity but addressed operational issues with the fixed undercarriage in rough terrain. Go 244 B-3 was adapted specifically for paratroop operations, featuring a strengthened floor, additional reinforcement in the fuselage, and twin rear jump doors to facilitate rapid exits during drops. Limited to around 20 units, primarily for airborne forces, this variant included four-bladed fixed-pitch wooden on some examples to simplify maintenance amid supply shortages, though this reduced overall performance. Its specialized configuration prioritized quick deployment over versatility, with conversions from B-1 airframes. Go 244 B-4 combined the B-2's semi-retractable undercarriage with the B-3's twin doors, optimizing the for both improved ground operations and paratroop or supply drops in varied environments. Production was limited, forming part of the later B-series output. Go 244 B-5 functioned as a dual-control trainer variant, equipped with additional instrumentation and yokes for instructor-pilot operations to support crew training. Produced in small quantities of about 10 units, it retained the core B-series but emphasized educational roles, allowing simultaneous control during flight instruction on the transport's handling characteristics. These were among the last to see limited assembly before program curtailment. Go 244 C emerged as an experimental variant testing fixed-pitch propellers paired with Gnome-Rhône 14M-04 or -05 series engines, aimed at reducing mechanical complexity and maintenance demands in forward areas. Only a few were constructed, but the design was not widely adopted due to noticeable losses in speed and climb rate compared to variable-pitch counterparts. This iteration highlighted ongoing efforts to adapt the aircraft for austere conditions, though it remained non-standard. Other minor adaptations included engine substitutions, such as replacing Gnome-Rhône units with captured Soviet radials in some Eastern Front examples, driven by acute shortages of French-sourced components. These field modifications, applied to a handful of B-series aircraft, maintained basic transport functionality but often compromised reliability in harsh environments.

Operational History

Service Entry and Initial Deployments

The first deliveries of the Gotha Go 244 to transport units occurred in March 1942, with initial aircraft assigned to Kampfgruppe zur besonderen Verwendung 104 (KGrzbV 104) based in and KGrzbV 106 on . These early units achieved operational readiness by spring 1942, enabling the type's integration into active service as a powered troop and supply transport derived from the Go 242 glider. Initial crew training took place at Luftwaffe facilities in Germany, where pilots and gunners familiarized themselves with the aircraft's short takeoff and landing (STOL) capabilities and defensive armament procedures, noting its handling characteristics closely resembled those of the unpowered Go 242. The training emphasized the Go 244's role in rapid resupply operations, leveraging its design for austere field use, though the captured Gnome-Rhône 14M engines required specific maintenance protocols due to their French origins. The Go 244's combat debut came in spring 1942 during the campaign, where it supported resupply missions to isolated garrisons in and , transporting troops, equipment, and light vehicles such as the Kübelwagen to forward positions. Primarily assigned to special-purpose transport groups like KGrzbV 104 and 106, the filled critical logistical gaps in the Mediterranean theater, though its slow speed and vulnerability to fighters limited mission profiles to escorted convoys. Early operations revealed significant challenges, including engine reliability problems with the underpowered radials, which led to high mechanical attrition rates in the initial months of service. In 1942, Luftwaffe production chief critiqued the design for its inadequate range of approximately 600 km, deeming it operationally restricted for extended supply routes. These issues prompted ongoing modifications, but they underscored the Go 244's transitional role between glider and fully capable transport.

Major Theaters and Challenges

The Gotha Go 244 saw its primary operational deployments in the Mediterranean theater, particularly supporting Axis forces in during 1942 and early 1943. Assigned to units such as zur besonderen Verwendung (KGrzbV) 106 based in and , the facilitated resupply missions for Erwin Rommel's , including efforts to sustain troops in amid the advancing Allied forces. These operations exposed the Go 244 to intense interdiction by (RAF) fighters, resulting in heavy attrition as the slow-moving transports became easy targets during convoy flights across the region. On the Eastern Front, the Go 244 entered service from late , with squadrons like the 7th Staffel of Transportgeschwader 4 operating from bases in . It contributed to relief efforts during the Demyansk and was considered for the Stalingrad but ultimately not used due to logistical constraints and harsh weather conditions. However, engine reliability issues with captured French Gnome-Rhône powerplants, compounded by spare parts shortages, hampered effectiveness in the severe winter conditions. The Go 244's operational challenges stemmed largely from its inherent design limitations, which proved ill-suited to contested airspace. With a maximum speed of only 290 km/h (180 mph), it offered minimal evasion capability against Allied fighters and anti-aircraft fire, leading to significant losses across theaters during its brief service life. Fuel shortages and the inability to operate reliably on a single engine further exacerbated vulnerabilities, rendering it ineffective for sustained frontline resupply by late 1942. By late 1942, the Luftwaffe began phasing out the Go 244 from frontline combat roles, replacing it with more robust transports like the and the larger , which better withstood enemy threats. Surviving airframes were relegated to training duties or secondary logistics tasks until 1944, with no post-war utilization. While the type influenced subsequent German assault transport concepts by demonstrating the feasibility of powered glider conversions, it was widely criticized for failing to achieve the rapid, low-observable assault capabilities envisioned in its original glider heritage.

Technical Specifications

General Characteristics

The Gotha Go 244 B-1 was a twin-engine designed primarily for troop and cargo transport, featuring a of two pilots, with provisions for a single pilot in certain configurations and optional loadmaster or gunners as needed. It had a capacity for up to 23 fully equipped troops, 2,500 kg of freight, or equivalent setups for . Key dimensions included a length of 15.8 m, of 24.5 m, of 4.7 m, and wing area of 64.4 m². The 's empty weight was 5,100 kg, with a of 7,800 kg. It was powered by two Gnome-Rhône 14M 14-cylinder radial engines, each delivering 700 hp (522 kW) at takeoff. The structure employed a wooden frame with fabric skin covering, arranged in a high-wing twin-boom configuration for enhanced stability and load-carrying capability. Later variants introduced minor modifications to capacity and powerplant options, but the baseline B-1 retained these core attributes.

Performance and Armament

The Gotha Go 244 B-1 achieved a maximum speed of 290 km/h (180 mph) at and a cruise speed of 270 km/h (168 mph), reflecting the limitations of its radial engines and glider-derived . These figures enabled short-range tactical transport missions but restricted its versatility compared to dedicated powered transports. The aircraft's range extended to 600 km (373 mi) with full , while the range reached up to 740 km in empty configuration. In terms of climb and altitude performance, the Go 244 B-1 had a service ceiling of 7,500 (24,600 ft) and a of 5.6 /s (1,100 ft/min), allowing it to operate effectively in low- to medium-altitude environments typical of assault glider support roles. Takeoff performance included a ground run of 180 with flaps deployed, while the stall speed was 110 km/h, facilitating operations from austere forward airfields despite the fixed undercarriage on early models. Defensive armament on the Go 244 B-1 consisted primarily of one 7.92 mm in the dorsal position for rearward coverage, supplemented by two 7.92 mm MG 81 machine guns in side beam mounts to protect against lateral threats. Troops could additionally fire personal weapons through ports, enhancing close-range defense during vulnerable approach and extraction phases. This configuration provided basic self-protection but was inadequate against determined fighter interception, underscoring the 's reliance on escort cover.
