Bushnell’s Turtle Submersible

Side view

In 1776, during the American Revolution, inventor David Bushnell decided to take his skills to the next level and build a submarine. And not just any submarine, mind you – this one was specifically designed to attack British ships!

Now, you might be thinking, “But wait, how could a guy in the 18th century possibly build a functional submarine?” Well, let me tell you, Bushnell was no ordinary inventor. He was a genius, a visionary, and a bit of a madman.

Turtle (also called American Turtle) was the world’s first submersible vessel with a documented record of use in combat. It was built in 1775 by American David Bushnell as a means of attaching explosive charges to ships in a harbor, for use against Royal Navy vessels occupying American harbors during the American Revolutionary War. More on Wikipedia.

The submarine he built was called the Turtle, and it was shaped like, you guessed it, a turtle. It was about six feet long and three feet wide, and it had a hatch on top that could be opened and closed by the operator.

Akula Class Nuclear Submarine.

The Akula class submarines, also known as Project 971 Shchuka-B (NATO reporting name: Akula), stand as a testament to Russia’s prowess in submarine technology. These formidable underwater vessels have played a crucial role in the country’s naval capabilities and have garnered attention for their advanced features and capabilities. In this article, we delve into the fascinating world of the Russian Akula class submarines, examining their history, design, capabilities, and strategic significance.

History and Development:

The Akula class submarines were developed during the Cold War era by the Soviet Union to counter the perceived threat posed by the United States Navy’s submarine fleet. The construction of the first Akula-class submarine, the K-284 Akula, began in the early 1980s, and the class eventually included several submarines with different modifications.

Design and Features:

  1. Size and Dimensions: The Akula-class submarines are sizable vessels, measuring around 110 meters (360 feet) in length. Their large size allows for greater endurance and accommodates a substantial crew and advanced equipment.
  2. Stealth and Hydrodynamics: The Akula submarines are designed with stealth in mind, featuring a streamlined hull and advanced sound-dampening technologies to reduce their acoustic signature. This enhances their ability to operate covertly and avoid detection by enemy vessels.
  3. Armament: Armed with a variety of weapons, including torpedoes and anti-ship missiles, Akula submarines are versatile in their offensive capabilities. They can carry a mix of torpedoes in their forward torpedo tubes and have the ability to launch cruise missiles from vertical launch systems.
  4. Nuclear Propulsion: The Akula-class submarines are powered by a nuclear reactor, providing them with an extended range and the ability to remain submerged for prolonged periods. This nuclear propulsion system significantly enhances their operational capabilities compared to conventionally powered submarines.
  5. Crew Accommodations: These submarines feature advanced living quarters for the crew, equipped with amenities to support long deployments beneath the ocean’s surface. This includes sleeping quarters, a galley, and recreational spaces, ensuring the crew’s well-being during extended missions.

Operational Capabilities:

  1. Underwater Endurance: The Akula class submarines are known for their impressive underwater endurance, enabling them to conduct extended patrols and remain submerged for weeks or even months at a time. This makes them formidable assets for strategic and tactical naval operations.
  2. Surveillance and Intelligence Gathering: Equipped with advanced sonar systems and sensors, Akula submarines are capable of conducting surveillance and intelligence-gathering missions. Their ability to operate quietly and stealthily enhances their effectiveness in monitoring and tracking potential adversaries.

Strategic Significance:

The Akula class submarines hold strategic importance for the Russian Navy, serving as both a deterrent and a powerful tool for projecting force. Their ability to operate in various environments, coupled with advanced technology, ensures that they remain a formidable presence in the underwater domain.


The Russian Akula class submarines stand as a testament to the nation’s commitment to maintaining a powerful and technologically advanced naval fleet. With their impressive design, advanced features, and strategic capabilities, these submarines continue to play a crucial role in shaping the dynamics of naval warfare and undersea operations. As technology evolves, the Akula class submarines remain a key component of Russia’s maritime defense strategy, securing their place in the annals of naval history.

Astute Class Nuclear Submarine

We have a newer version of the Astute Class 3d model. Its 1meter long and R/C capable. <–Click to see it

The Astute class is the latest class of nuclear-powered fleet submarines (SSNs) in service with the Royal Navy. The class sets a new standard for the Royal Navy in terms of weapons load, communication facilities and stealth. The boats are being constructed by BAE Systems Submarines at Barrow-in-Furness. Seven boats will be constructed: the first of class, Astute, was launched by Camilla, Duchess of Cornwall, in 2007, commissioned in 2010, and declared fully operational in May 2014. The Astute class is the replacement for the Trafalgar-class fleet submarines in Royal Navy service.
