The I-400 Class Submarine (Sen-Toku type) is a high-quality, photo-real model capturing the largest submarine ever built before the nuclear era. This model features the massive watertight hangar designed to house three Aichi M6A Seiran floatplanes, the large offset conning tower, and the prominent deck catapult system used for aircraft launch. It is depicted in an authentic Imperial Japanese Navy dark grey-and-red hull scheme, including specialized deck cranes and multiple defensive anti-aircraft gun mounts.

The model has a fully textured, detailed design that allows for high-resolution renders. All renders are provided without postprocessing.

Suitable for all major 3D software suites, including Blender, 3ds Max, Maya, and Unreal Engine. Ideal for historical maritime simulations, educational projects, and naval warfare animations.
