Hasegawa Plastic Model Kit Messerschmitt Bf 109G-10 ST22 — 1:32

Manufacturer and kit

Hasegawa is a Japanese scale-model manufacturer particularly well known for aircraft kits. This ST-series kit represents the late-war Bf 109G-10, one of the final major production versions of the famous German fighter.

The finished model is approximately 310 mm long with a 283 mm wingspan. The kit contains the injection-moulded airframe components, cockpit, landing gear, propeller, engine/cowling details, clear parts, decals and assembly instructions. The original boxing provides three decal options, according to a contemporary kit review.
The full-size Messerschmitt Bf 109G-10

The Messerschmitt Bf 109 was Germany's principal single-seat fighter throughout much of the Second World War. Designed in the 1930s by the Bayerische Flugzeugwerke/Messerschmitt team under Willy Messerschmitt, it evolved through numerous versions as engines, armament and aerodynamic equipment were improved.

The Gustav, or Bf 109G, became the dominant production family from 1942 onward. By 1944 the earlier G-series aircraft were being overtaken in performance by newer Allied fighters, leading to further development around the more powerful Daimler-Benz DB 605D engine.
Bf 109G-10 development

The G-10 was introduced during the final phase of the war, beginning in late 1944. It was not simply a completely new aircraft; rather, it combined the existing Bf 109G airframe with the latest available engine and production improvements.

The principal powerplant was the Daimler-Benz DB 605D, with MW 50 methanol-water injection available to increase emergency power. Contemporary technical information gives approximately 1,800 hp at take-off, with higher performance available under MW 50 conditions.

Externally, G-10 aircraft could display a number of late-production features, including the characteristic enlarged engine cowling associated with the DB 605D installation and various production changes resulting from the increasingly dispersed manufacturing system.
Performance

Representative Bf 109G-10 characteristics include:

Crew: 1

Engine: Daimler-Benz DB 605D

Power: approximately 1,800 hp at take-off with MW 50

Maximum speed: approximately 680–690 km/h depending on configuration and altitude

Armament: typically 1 × 20 mm MG 151/20 cannon firing through the propeller hub and 2 × 13 mm MG 131 machine guns

Optional armament: underwing cannon pods or bombs depending on aircraft and mission

Role: Fighter / interceptor

The exact performance and external appearance varied because late-war Bf 109s were produced by several manufacturers and factories using differing combinations of components.
Combat history

The G-10 appeared when Germany was increasingly operating defensively against overwhelming Allied air power.

Its principal tasks included:

Intercepting Allied bomber formations

Fighting Allied escort fighters

Defence of German territory

Local air superiority

Ground attack when required

The Bf 109G-10 was used on both the Western and Eastern Fronts and in the Reich air-defence campaign.

The aircraft's high power-to-weight ratio and strong climb performance remained valuable, particularly against bombers, but late-war Allied fighters such as the North American P-51D Mustang, Republic P-47 Thunderbolt and Supermarine Spitfire Mk.IX/XIV operated in an increasingly sophisticated environment.
Late-war production

The G-10 is particularly interesting because it illustrates the increasingly difficult German aircraft-production situation in 1944–45.

Aircraft were produced by different manufacturers, including Messerschmitt, Erla and WNF, and consequently individual aircraft can exhibit noticeable differences in cowling, access panels, camouflage and other details.

This is worth remembering when building the Hasegawa kit: a particular decal option should be matched to the appropriate production features rather than assuming every G-10 looked identical.
Armament

The standard armament was centred around the MG 151/20 20 mm cannon, mounted centrally and firing through the propeller shaft.

Two MG 131 13 mm machine guns were mounted above the engine.

Some aircraft were fitted with additional MG 151/20 cannon gondolas beneath the wings, increasing firepower at the expense of aerodynamic performance.

This heavy armament was particularly useful against Allied four-engine bombers.
Historical significance

The Bf 109G-10 represents one of the final stages in the development of a fighter that had been in continuous evolution since the Spanish Civil War.

The basic airframe originated in the mid-1930s, yet successive improvements in engines, superchargers, armament and aerodynamics allowed the Bf 109 to remain in frontline service throughout the Second World War.

The G-10 is therefore a particularly interesting modelling subject because it combines the familiar appearance of the Bf 109 with the highly developed late-war engineering of the DB 605D-powered aircraft.
