SMS Sachsen Ironclad

A Coastal Defender from the Early German Empire

The SMS Sachsen was the lead ship of the Sachsen-class ironclads, a group of four armored vessels built for the Imperial German Navy in the 1870s. Alongside her sister ships—Bayern, Württemberg, and Baden—she represented a distinctly different approach to naval warfare compared to the ocean-going ironclads of Britain and France. Rather than projecting power across distant seas, these ships were designed with a more focused mission: defending Germany’s coastline and controlling the confined waters of the North Sea and Baltic.

This role shaped every aspect of their design. The Sachsen-class ships were relatively compact but heavily armored, with a low freeboard and a strong emphasis on protection and firepower over range. Their layout reflected the transitional nature of naval engineering at the time—positioned between earlier broadside ironclads and the more advanced turret ships that would follow. Central battery arrangements, thick armor belts, and powerful main guns gave them serious defensive capability, even if their seaworthiness in rough open water was limited.

Although not as famous as later battleships, the Sachsen-class played an important role in the early development of the Imperial German Navy. They embodied a strategic mindset focused on coastal defense, deterrence, and controlled engagement, rather than global reach. Over time, as naval doctrine evolved and larger, more capable ships entered service, the Sachsen-class became less central—but they remain a fascinating example of a navy defining its identity during a period of rapid technological change.

Freedom-Class Littoral Combat Ship

A New Kind of Warship

When the United States Navy introduced the Littoral Combat Ship concept in the early 2000s, it represented a fundamental rethinking of what a modern surface combatant could and should be. Traditional warships were large, heavily armed, and designed for blue-water operations far out at sea. The LCS was conceived for an entirely different environment — the littoral zone, the shallow coastal and near-shore waters where conventional warships struggle to operate effectively, yet where a growing number of real-world threats were emerging. Fast, nimble, and built around a modular mission system architecture, the LCS was envisioned as a vessel that could be rapidly reconfigured for entirely different combat roles depending on the threat — surface warfare one week, mine countermeasures the next, anti-submarine operations the week after.

The Freedom Class is one of two LCS variants developed for the US Navy, built by Lockheed Martin and Fincantieri Marinette Marine at their Wisconsin shipyard. Where its sister variant, the Independence Class, adopted a radical trimaran hull form, the Freedom Class took a more conventional semi-planing monohull approach — sleek, fast, and remarkably capable for its size. Displacing around 3,900 tons at full load and stretching just under 116 meters in length, Freedom-Class ships are powered by a combined diesel and gas turbine propulsion system driving quadruple waterjets, allowing them to reach speeds well in excess of 40 knots — making them among the fastest warships of their displacement in any navy in the world.

Thornycroft Coastal Motor Boat 55ft

Britain’s Secret Weapon of the Seas

From World War I Torpedo Raider to Modern 3D-Printed RC Model


Origins: A Bold Idea from Junior Officers

Few naval weapons have such an unlikely origin story as the Coastal Motor Boat (CMB). In the summer of 1915, three junior officers of the Harwich Striking Force — Lieutenants Hampden, Bremner, and Anson — hatched an audacious proposal: could a small, fast motor boat, armed with a torpedo, travel over enemy minefields and attack Imperial German Navy ships at anchor in their heavily defended bases?

The Admiralty gave tentative approval, and a Staff Requirement was issued for a new type of vessel to serve in the North Sea. The specifications were demanding. The boat had to be capable of at least 30 knots when fully loaded, carry enough fuel for a meaningful radius of action, and be armed with torpedoes, depth charges, or mines, supplemented by light machine guns. Several established shipbuilders were approached, but only one company believed the requirement could actually be met: John I. Thornycroft & Company.

Tupolev G-5 Torpedo Boat

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.
