1/72 IJN 12 cm/45 (4.7") 10th Year Type

1/72 IJN 12 cm/45 10th Year Type: Imperial Japanese Navy Dual-Purpose Secondary Battery Fidelity

Bring an exceptional layer of technical density, structural authority, and naval artillery realism to the gun decks, secondary battery sponsons, and weather deck galleries of your large-format Imperial Japanese Navy models with the masterfully engineered 1/72 Scale IJN 12 cm/45 (4.7") 10th Year Type. Introduced in 1921 (the 10th year of the Taishō era) as a specialized high-angle dual-purpose weapon derived from the earlier 3rd Year Type surface gun, the 12 cm/45 10th Year Type served as a cornerstone of IJN close-in anti-aircraft defense and anti-torpedo-boat firepower throughout the Pacific War. Widely deployed across heavy cruisers (Furutaka, Aoba, and Myōkō classes before their late-1930s modernization), aircraft carriers (Hōshō, Ryūjō), light cruisers, fleet submarines, and coastal defense escorts, this hand-worked gun mount combined high rates of fire with rugged mechanical reliability. Scaled to the commanding 1/72 collector scale, this dedicated ordnance upgrade faithfully captures the slender rifled barrel, counterweight equilibrators, horizontal sliding breech-block, elevating handwheels, training gear racks, and riveted pedestal carriage of original Kure Naval Arsenal ordnance schematics with flawless structural fidelity.

Engineering Precision and Imperial Japanese Naval Ordnance Architecture

At 1/72 scale, open-mount naval artillery steps directly into the foreground, where thick, solid-molded plastic kit barrels, blobby handwheels, fused sighting apparatus, and soft-cornered pedestals immediately compromise an ambitious capital ship or submarine build. This replica 12 cm/45 10th Year Type captures the purposeful, intricate mechanical geometry of wartime Japanese naval ordnance with surgical micro-clarity, eliminating the clumsy cross-sections, mold parting lines, and flash typical of mass-production injection moldings or heavy white-metal castings. Deployed onto the gun platform or deck sponson of your 1/72 scale build, the assembly features true-to-scale physical relief, creating realistic physical shadow lines and deep mechanical contrast that standard kit placeholders cannot match.

• Museum-Quality Arsenal Replication: Developed using original technical layouts, historical Imperial Japanese Navy technical bureau blueprints, and Kure Naval Arsenal records to accurately reproduce the exact physical dimensions, trunnion centerline height, breech-block layout, and carriage angles of the operational 10th Year Type gun mount.
• Prototypical 1/72 Scale Scope: Specifically engineered for large-format 1/72 scale Japanese warship builds, large-scale fleet submarine models, scratch-built coastal escorts, carrier gun sponson cutaways, and museum-grade naval diorama presentations.
• Exposed Hardware & Mechanical Detail: Authentically captures the stepped barrel contour, muzzle crown, counter-recoil cylinder housing, manual elevation and training gear arcs, crew handwheels, telescopic sight mounts, loader's platform, and heavy conical pedestal base with raised perimeter foundation bolts.
• True-to-Scale Volumetric Depth: Replicates the true physical three-dimensional presence of heavy forged naval steel and machined bronze, casting realistic deep shadows through open sighting brackets, between the recoil slide tracks, and beneath the gunner's foot platforms.
• Streamlined Deck Integration: Engineered with a precision-molded base contact pin and flush-fit circular foundation flange designed to seat cleanly, squarely, and securely flush into standard 1/72 scale deck apertures or gun wells, drastically reducing assembly friction and streamlining installation.
• Intelligent Structural Engineering: Expertly designed in High Detail Resin Grey with optimized micro-proportions to manage material mass while preserving maximum rigidity, ensuring a dead-straight, sag-free gun barrel and crisp gear teeth that resist drooping, bending, or thermal distortion over time.

Premium Material: High Detail Resin Grey

To satisfy the absolute highest demands of micro-detailed static presentation across delicate scale naval architecture and specialized deck weaponry, this 12 cm/45 10th Year Type mount is crafted exclusively from premium High Detail Resin Grey.

• Exceptional Feature Definition: This premier formula achieves surgical multi-dimensional precision and an ultra-smooth, non-porous surface finish, capturing the finest mechanical facets—from scale-thin handwheel spokes and sighting scope reticle brackets to miniature breech levers and pedestal flange fasteners—with absolute sharpness and zero layer line distraction.
• Professional Foundation: Provides an ultra-smooth base specifically optimized for high-quality marine primers, fine-scale technical pin-washes, chipping mediums, micro-masking, and authentic wartime IJN vertical camouflage finishes, ensuring flawless paint adherence.
• Superior Quality: Manufactured by distefan 3d print, ensuring clean surfaces, true axial symmetry, and outstanding structural integrity for a luxurious, professional-grade finish.

Key Features and Specifications

• Accurate 1/72 Scale Precision: Precision-engineered for seamless, historically proportional integration with standard 1/72 scale Japanese naval models, custom scratch-built hulls, and museum-grade static displays.
• Historically Authentic Fleet Hardware: Faithfully represents the physical configuration of the standardized IJN 12 cm/45 10th Year Type dual-purpose high-angle naval gun utilized across cruisers, carriers, escorts, and submarines throughout World War II.
• Unified High-Integrity Architecture: Combines the barrel, recoil sleeve, sighting gear, elevating mechanism, crew footplates, and pedestal base into a cohesive, high-integrity unit, eliminating tedious micro-assembly, misaligned trunnions, and fragile adhesive joints.
• Lightweight Rigidity: Features an engineered structural profile that maintains exceptional structural stiffness across the slender barrel and open carriage framework while ensuring solid, flush attachment to elevated gun platforms.
• Unpainted Finish: Arrives completely unpainted, providing an open canvas for custom finishing. Customize the mount to reflect standard Imperial Japanese Navy arsenal gray shades such as Kure, Sasebo, Yokosuka, or Maizuru Naval Arsenal grays.
• The Definitive Dual-Purpose Weapon Overhaul: Replaces simplified, featureless plastic kit placeholders with a sophisticated, mechanically correct three-dimensional representation of vital Japanese high-angle naval artillery.

A Canvas for Battle-Tested Fleet Artistry

Arriving in its raw finish, the 1/72 IJN 12 cm/45 10th Year Type serves as the ultimate starting point for advanced multi-layer painting, precise component color-blocking, and realistic maritime weathering.

• The Imperial Navy Color Scheme: Base-coat the pedestal carriage, recoil housing, and carriage side plates in authentic period-correct IJN vertical arsenal gray—such as Kure Naval Arsenal Gray (a medium-dark neutral gray) for major fleet combatants, or Sasebo/Yokosuka Gray depending on your vessel's historical builder yard. Paint the sliding gun barrel sleeve, recoil piston rods, and breech face in dark gunmetal, polished steel, or burnished graphite. Pick out the optical sight tubes, aiming handwheels, and foot pedals in dark oily iron or satin black to provide striking mechanical contrast against the surrounding naval gray.
• Realistic Frontline Operational Weathering: Mounted on open weather decks and exposed sponsons subjected to corrosive tropical Pacific salt spray, hot cordite propellant blast, and routine crew gun drills, this mount thrives on rich washes and fine weathering. Apply rich dark raw umber and soot black oil pin-washes into the gear teeth recesses, around the recoil cylinder glands, and along the pedestal foundation bolts to establish deep structural shadow definition. Add realistic weathering touches like subtle bare-metal silver highlights along handwheel rims and foot pedals where crewmen stood, faint cordite smoke staining fanning back from the muzzle, dried white sea-salt mineral crusting clustered in structural crevices, and vertical rust streaks weeping downward from base mounting fasteners to capture the true look of a combat-hardened Japanese warship in active Pacific service.
