Dark submarine with blue glowing veins in icy water near icebergs

The TUNDRA Dreadnought stretches to an impressive 225 meters in length while maintaining a slim, streamlined profile with a maximum beam of about 18 meters. Despite its extended length, the submarine retains a low and elongated silhouette, emphasizing speed and stealth over bulk. The narrow hull tapers sharply to a reinforced prow designed to cleave through dense Arctic ice and powerful underwater currents with ease. The outer hull is clad in Class-V Reinforced Obsidian Plating, a matte-black armor with subtle textural variations that resemble frozen rock formations. Interspersed along the plating are faint, icy-blue luminescent veins—thin, irregular lines that pulse slowly, giving the hull an eerie, almost living appearance in low light. These veins trace the seams and structural ridges, highlighting the submarine’s formidable frame. Atop the hull sits the sail, a compact and angular command deck that rises 9 meters tall above the submarine’s spine. Its streamlined, low-profile structure blends seamlessly with the hull’s jagged aesthetic, featuring beveled edges and a reinforced surface clad in the same Class-V Reinforced Obsidian Plating. Narrow, recessed 360-degree viewports are embedded along the forward face. Though smaller than traditional towers, the sail retains a commanding presence—hardened, utilitarian, and perfectly suited for Arctic navigation and control. The bow of the TUNDRA Dreadnought can be described as a recessed, angular “V”-shaped snout, resembling a See more
