1/350 USN 4-inch/50 (10.2 cm) Sub Deck Gun Set (2pcs): Sub-Surface Surface Battery Realism
Bring an exceptional layer of technical density, structural authority, and naval combat realism to the weather decks and gun flats of your waterline and full-hull American fleet submarine models with the masterfully engineered 1/350 Scale USN 4-inch/50 (10.2 cm) Sub Deck Gun Set (2pcs). Formally designated as the 4"/50 caliber Mark 9 gun on specialized wet-mount naval carriages, this rapid-fire naval rifle served as the signature surface attack armament aboard United States Navy submarines throughout the interwar era and the opening crucible of World War II—prominently fitted on S-class ("Sugar boats"), V-boats, and early fleet submarines operating throughout the Asiatic Fleet and Pacific theater. Designed to engage armed merchant vessels, finish crippled convoys, and shell shore installations without expending precious torpedoes, the sub-mounted 4"/50 was built with specialized corrosion-resistant alloys, tinned barrel linings, and waterproof muzzle tampions to survive continuous submersion under crushing deep-water patrol pressures. Scaled precisely to standard 1/350 naval scale, this dedicated 2-piece standalone upgrade captures the tapered stepped barrel, sliding breech block, open pedestal carriage, manual handwheel controls, training platform, and flanged deck mounting ring of original Bureau of Ordnance (BuOrd) blueprints with flawless structural fidelity.
Engineering Precision and Submarine Deck Weaponry Fidelity
At 1/350 scale, submarine deck guns are the primary mechanical and silhouette focal points along the low-slung, minimalist profile of a submarine hull, exposing barrel straightness, carriage framing, and mounting footpad proportions to close visual scrutiny. This 2-piece replica deck gun set captures the utilitarian, rugged industrial profile of American submarine artillery with surgical clarity, eliminating the soft contours, clunky out-of-scale barrels, missing handwheels, and flash distortion typical of mass-produced injection-molded plastic kit parts or soft white-metal castings. Deployed forward of the conning tower, aft on the cigarette deck, or arranged in twin gun flat configurations on your 1/350 scale build, each gun assembly features true-to-scale physical contours, creating realistic physical shadow lines and deep visual relief that basic kit placeholders cannot match.
- Museum-Quality Arsenal Replication: Developed using original technical layouts, historical U.S. Navy Bureau of Ordnance blueprints, and archival shipyard gun installation schematics to accurately reproduce the exact physical dimensions, stepped barrel taper, recoil cylinder housing, and base pedestal proportions of active wartime submarine wet mounts.
- Prototypical 1/350 Fleet Scope: Specifically engineered for 1/350 scale U.S. Navy submarine subjects—including S-class boats, V-class long-range cruisers, early fleet boat conversions, diorama harbor vignettes, and museum-grade static displays.
- Matched 2-Piece Fleet Set: Packaged as a dedicated 2-piece set, providing two complete 4-inch/50 caliber weapon stations to outfit dual-gun boats or multiple submarine builds across your miniature fleet.
- Exposed Hardware & Mechanical Detail: Authentically captures the 50-caliber barrel length, crisp muzzle crown, sliding breech mechanism, elevation gear arc, trainer and pointer handwheel spindles, crew standing platform, and circular deck mounting base with fastener bolt impressions.
- True-to-Scale Volumetric Depth: Replicates the true physical three-dimensional presence of heavy naval gun mounts, casting realistic open shadows beneath the barrel sleeve, through the open carriage trunnions, and across submarine deck teak planking or slotted steel plates with authentic mechanical contrast.
- Streamlined Deck Integration: Engineered with precision-molded flat base mounting footpads designed to seat cleanly and securely flush onto standard 1/350 scale submarine hull casings or raised gun tubs, drastically reducing assembly friction and streamlining installation.
- Intelligent Material Optimization: Expertly designed in High Detail Resin Grey with an optimized structural profile to manage material mass while preserving maximum rigidity, ensuring crisp, warp-free barrels that maintain dead-straight horizontal or elevated alignment without drooping over time.
Premium Material: High Detail Resin Grey
To satisfy the absolute highest demands of micro-detailed static presentation across delicate scale ordnance and specialized naval weapon mountings, this submarine deck gun set 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 razor-thin elevation handwheels to miniature breech block seams and deck flange bolt heads—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, micro-masking, and authentic wartime US Navy camouflage finishes, ensuring flawless paint adherence.
- Superior Quality: Manufactured by distefan 3d print, ensuring clean surfaces, dead-straight barrel concentricity, and outstanding dimensional integrity for a luxurious, professional-grade finish.
Key Features and Specifications
- Accurate 1/350 Scale Precision: Precision-engineered for seamless, historically proportional integration with standard 1/350 scale U.S. Navy submarine kits, scratch-built waterline hulls, and museum-grade diorama showcases.
- Historically Authentic Fleet Hardware: Faithfully represents the physical configuration of the standardized Mark 9 4-inch/50 caliber submarine wet-mount deck gun operated during the interwar era and World War II.
- Set Composition: Includes two (2) complete high-detail 4-inch/50 caliber submarine deck guns.
- Hollowed Lightweight Design: Features an optimized structural geometry that minimizes weight while maintaining rigid structural integrity across slender barrels and carriage mountings.
- Unpainted Finish: Arrives completely unpainted, providing an open canvas for custom finishing. Customize the assemblies to reflect standard pre-war overall black, Measure 9 (matte black), Measure 10, Measure 32/3SS-B submarine camouflage schemes, or weathered sea-duty finishes.
- The Definitive Main Battery Overhaul: Replaces simplified, brittle kit plastic parts with a sophisticated, historically correct three-dimensional representation of vital naval submarine artillery.
A Canvas for Battle-Tested Fleet Artistry
Arriving in its raw finish, the 1/350 USN 4-inch 50 (10.2 cm) Sub Deck Gun Set (2pcs) serves as the ultimate starting point for advanced multi-layer painting, precise component color-blocking, and realistic maritime weathering.
- The Fleet Submarine Scheme: Base-coat the mounting pedestal, carriage cheek plates, and gun barrel in authentic period-correct submarine colors—such as overall dull Black (Measure 9), dark Ocean Gray (5-O), or light Haze Gray (5-H) depending on your boat's specific theater and operational date. Paint the sliding breech block, operating levers, and training handwheels in dark gunmetal, burnished steel, or oily graphite to represent heavy steel machinery treated with heavy protective grease against corrosive salt water. For boats in harbor trim, highlight the muzzle tampion plug in weathered wood or painted brass.
- Realistic Frontline Operational Weathering: Micro-scale deck weapons thrive on controlled washes and environmental staining. Apply thin dark raw umber and soot black oil washes into the open elevation gear teeth, around the trunnion pivots, and along the deck mounting flange seam to establish deep structural shadows. Add realistic weathering effects like subtle edge highlights on the crew handwheels and platform edges where gunners operated the mount during night surface actions, delicate rust streaks weeping downward from the baseplate bolts toward deck scuppers, dried white salt spray mineral crusting across the windward faces of the barrel from running surfaced through heavy swells, and subtle soot residue around the muzzle crown to capture the look of a veteran fleet boat returning from an aggressive war patrol.
