The USS IDAHO (SSN 799), the US Navy's new nuclear submarine, is already in the water and ready for its final stage
The US Navy has just given another significant step to strengthen its naval power with the launch of the new nuclear submarine USS IDAHO (SSN 799), the latest and most modern Virginia-class submarine. The launch debut, or “float off”, took place on the Thames River, in Connecticut, marking the beginning of the final equipping phase before its entry into service, scheduled for spring 2025.
O new nuclear submarine USS IDAHO is one of the U.S. Navy's most ambitious and advanced projects, reflecting years of meticulous development and construction. Launched in 2020, the submarine is now in direct contact with the water, an important milestone symbolizing the completion of primary construction and the start of final testing and adjustments.
New nuclear submarine of the US Navy goes for testing
During the next few months, the companies Newport News Shipbuilding and General Dynamics Electric Boat, responsible for the construction, will work on the installation of the latest equipment and will perform a series of rigorous tests to ensure the USS IDAHO is ready for its mission.

20 Virginia-class submarines
The USS IDAHO is expected to enter service in the spring of 2025, adding to an already formidable fleet of approximately 20 Virginia-class submarines. The US Navy continues to invest heavily in this class of nuclear submarines, with a dozen other units in different phases of construction.
Stealth aspect
What makes Virginia-class submarines like the USS IDAHO so sophisticated is their ability to operate with an extremely low acoustic signature. This means they are difficult to detect on enemy instruments, allowing them to operate with greater stealth. This stealth aspect is one of the main differentiators of modern nuclear submarines, and the USS IDAHO is no exception.
9 MW S210G nuclear reactor
With a 9 MW S210G nuclear reactor and an auxiliary propulsion diesel engine, the new nuclear submarine is capable of generating sufficient electrical energy to operate its “pumpjet” propulsion system, developed by BAE Systems. Unlike traditional propeller systems, this system ensures quieter and more efficient operation.
The USS IDAHO incorporates several technological innovations
Its masts are modular and include a photonic mast, which can be controlled with an Xbox-like joystick – an innovation that not only makes control easier, but also reduces costs. Speaking of savings, the use of commercial off-the-shelf (COTS) components was a strategy adopted to cut costs without compromising efficiency or safety.
Built with an open architecture, the USS IDAHO is ready to receive upgrades over time, ensuring it remains ahead of the curve in terms of naval technology. It will be capable of launching Tomahawk cruise missiles, UGM-84 Harpoon missiles and Mk-48 torpedoes, making it a true force to be reckoned with.
US Navy reaffirms its leadership position
With the launch of the USS IDAHO, the U.S. Navy reaffirms its leadership position in undersea military technology, continuing the tradition of innovation and naval power that has been its hallmark for decades. THE new nuclear submarine not only strengthens the existing fleet, but also represents a step forward in defending American interests in deep waters.
