Arcturus‑Class Submarine

by

The Future of Stealth, Now at Your Desk

Where Science Fiction Meets the Workshop Bench

In August 2022, at the Army‑2022 defence expo, the Rubin Design Bureau unveiled a concept that looked more like a low‑observable aircraft than a traditional submarine. Named Arcturus (Арктур) after the brightest star in the northern celestial hemisphere, the design is the Russian answer to a new generation of ballistic‑missile submarines (SSBNs) that will eventually replace the Borei class. While the real vessel is still a paper project – its keel isn’t expected to be laid until the late 2030s, with operational capability projected for the 2040‑2050 timeframe – its faceted, angular hull and revolutionary propulsion system have already captured the imagination of naval analysts and hobbyists worldwide.

At EndtaS we decided to bring that future a little closer to the present. Our 75 cm Arcturus‑Class Submarine is a highly detailed, fully articulated 3‑D printable model that captures the spirit of Rubin’s concept while remaining practical for home printers. This article dives into what makes the real Arcturus special, what we’ve added to our 1 : ~200 scale replica, and how you can build it at home.

Tupolev G-5 Torpedo Boat

by

History, Design, and Our 1:24 Scale 3D Printable Model

The Tupolev G-5 occupies a unique place in naval history as one of the most distinctive fast attack craft of the interwar and early Second World War period. Designed in the early 1930s by the Tupolev Design Bureau, the G-5 was the Soviet Union’s answer to the growing demand for high-speed torpedo boats capable of striking larger surface vessels and withdrawing before retaliation. Built primarily from duralumin, the same lightweight alloy used in aircraft construction, the G-5 reflected its aviation heritage in both material choice and overall design philosophy.

Compact, aggressively streamlined, and extraordinarily fast for its time, the G-5 was capable of speeds exceeding 50 knots under ideal conditions, making it one of the fastest military vessels of its era. It carried its torpedoes externally, launched rearward from open cradles—a bold and unconventional solution that allowed the hull to remain slim and hydrodynamically efficient. Over its service life, the G-5 appeared in numerous configurations, with variations in armament, deck equipment, crew layout, and superstructure, adapting to changing combat requirements throughout the 1930s and into World War II.

Qing-Class Submarine

by

Interpreting a Modern Naval Enigma Through 3D Modeling

The Qing-class submarine represents one of the most modern and least publicly documented submarine designs to emerge in recent decades. As a nuclear-powered ballistic missile submarine (SSBN) developed by China, it occupies a strategic role that is inherently opaque, with limited officially released plans, drawings, or dimensional data. This combination of technological significance and visual secrecy makes the Qing class both fascinating and challenging to interpret—particularly for modelers working without access to authoritative blueprints.

Our Qing-class 3D model is therefore not a literal reproduction, but a carefully researched and technically reasoned interpretation. Publicly available photographs, satellite imagery, comparative analysis with earlier Chinese submarine classes, and established submarine design principles were used to reconstruct the vessel’s overall proportions, hull geometry, and defining external features. Where reliable information ends, informed design judgment begins—always with the goal of maintaining visual plausibility, structural coherence, and a clean, manufacturable result.

USS Growler (SSG-577) 3D model

by

A Cold War Missile Submarine and It’s Mighty Weapon the Regulus 1, Recreated in 3D

The USS Growler (SSG-577) occupies a unique and transitional place in naval history. Conceived during the early years of the Cold War, Growler was part of the U.S. Navy’s first serious attempt to field a submarine-launched strategic missile capability. Long before ballistic missile submarines became dominant, vessels like Growler were designed around the Regulus cruise missile, a large, aircraft-like weapon that required deck storage, surface launch, and complex handling procedures. This requirement fundamentally shaped the submarine’s appearance, resulting in its most recognizable feature: the massive twin missile hangars integrated into the forward deck.

Sjöormen-Class Submarine

by

Swedish Innovation Beneath the Surface:

The Sjöormen-class submarines occupy a unique and important place in Cold War naval history. Introduced by Sweden in the late 1960s, the class represented a decisive break from traditional submarine design thinking and placed Swedish underwater engineering at the forefront of diesel–electric submarine development. Built for operations in the confined, shallow, and acoustically complex waters of the Baltic Sea, these submarines prioritized stealth, maneuverability, and hydrodynamic efficiency over raw size or speed. As a result, the Sjöormen class became widely respected—both publicly and quietly within naval circles—for its advanced design choices and remarkably low acoustic signature.

Scorpène-Class Submarine

by

1:87 Scale, 763mm 3D Printable Model

The French Scorpène-class submarines represent one of the most successful and widely adopted modern submarine designs in the world. Developed by Naval Group (formerly DCNS), the Scorpène class combines compact dimensions with advanced stealth, long endurance, and multi-role flexibility. These diesel-electric attack submarines have been built for and operated by several nations — including India, Brazil, Chile, and Malaysia — each version tailored to local operational requirements. With their quiet propulsion systems, advanced combat management, and modular construction, the Scorpène-class has become a global standard for next-generation conventional submarines.

To bring this modern masterpiece into digital form, we created a 1:87 scale, 3D printable model of the Scorpène-class submarine, designed to capture both the beauty and engineering precision of the original vessel. Measuring 763 mm in length, this version consists of 35 separate high-poly STL files, optimized for easy printing with most FDM and resin printers. The hull interior is mostly empty, with a 5–7 mm wall thickness, reinforced by three internal bulkheads that ensure alignment and add rigidity during assembly. These features make the model both durable and straightforward to build, even for large-format prints.
