The latest Russian nuclear-powered attack submarine is the Project 885 Yasen (Western designation: Graney class). At least 36 different kinds of weapons are on board. Torpedoes like the Spearfish, Sub-Harpoon, and Tomahawk are launched from these. Six 533 mm torpedo tubes are installed in these submarines for use in combat. The new Trafalgar-class ships of the Astute class are more stealthy and equipped with a greater arsenal than their predecessors of the Trafalgar class. The Swiftsure class attack submarines will be replaced by these new ones. So far, seven boats of this type are in the works.
This year, the Royal Navy took delivery of its first nuclear-powered attack submarine of the new Astute class. Tomahawk land-attack cruise missiles, with a range of 1,700 kilometers, are fired from these. In terms of noise, Virginia is said to be comparable to the Seawolf-class.Ī total of twelve Vertical Launch System (VLS) tubes are installed on submarines of the Virginia class. To minimize their sonic signature, the Virginia class submarines have a newly developed anechoic coating, segregated deck structures, and a redesigned propulsor. The construction of 30 nuclear-powered attack submarines of the Virginia class is currently on track to begin soon. As a smaller, less costly, and more adaptable alternative to the Seawolf Class, Virginia was developed. Submarines of the Virginia class, powered by nuclear propulsion, will replace the Los Angeles-class vessels in the US Navy’s fleet. Compared to an older Los Angeles class submarine moored at the dock, a Seawolf at 25 knots emits less noise than the latter. Passive sonar arrays can only detect submarines traveling at a speed of 5 knots or less, while the Seawolf-class is said to be able to cruise at 20 knots and still be undetectable. Even when traveling at high speeds, it remains very silent.
Submarines of the Seawolf-class are among the most silent ever built.
