The Judicious class (Etrurian: Guidizioso) is the new class of nuclear-powered ballistic missile submarine produced by Etruria and operated by the United Etrurian Navy, the vessel is the first nuclear-powered ballistic missile submarine to enter service with the Papal Navy, whilst previously it relied upon conventional submarines for local area submarine-launched ballistic missile coverage - most of which were warheads of high-explosive or chemical in nature.
The Guidizioso class submarines are the most expensive vessels built for the Papal Navy, with each reportedly costing $3.5 billion, five are planned in total. The Guidizioso Class in itself is highly controversial, due to Etruria's self-declared lack of nuclear weapons, this has led many to question why the UEN is now in possession of submarines capable of carrying nuclear warheads. At almost 190 meters long, they are also the largest submarines built in Etrurian history.
Design and history
The first design work was laid down in mid-1990s and the first Judicious class submarine was laid down over ten years later in 2007. A new submarine launched ballistic missile was designed in parallel to the Judicious, the T-740 Drago entered service with the first vessel, the ENS Guidizioso. The submarine needed to be redesigned to accommodate the new missile. The vessels are being built at the Santa Fiora Naval Shipyards by [[Vasari Solutions] and was designed by the Etrurian State Maritime Design Office. Advances include a compact and integrated hydrodynamically efficient hull for reduced broadband noise and the addition of two NORT CA310 optronic masts. The Judicious submarines are approximately 189 metres (620 ft) long, 13 metres (43 ft) in diameter, and has a maximum submerged speed of at least 46 kilometres per hour (25 kn; 29 mph). They are equipped with two floating rescue chamber designed to fit in the whole crew.
The Judicious class operates active coating with embedded electronics that will determine the frequency at which the radar of the opponent operates and launch its own signal of the same frequency but in opposite phase. The development will be universal for all Type 011 and Type 089 submarines and will have to work with advanced computer systems for the future submarine fleet the aim being that the coating will not just absorb the sonar signal (as do the existing passive coating materials of submarine hulls), but neutralize incoming radiation. The passive anti sonar coating, is made of a composite material based on rubber, the doubled hull, rather than operating a gap between the inner and outer hull is filled with rubber blocks that further reduce sound emissions. The hull is noted as a compact and integrated hydrodynamically efficient hull for reduced broadband noise, this design was taken from the Type 089 class, both the ENS Guidizioso and ENS Sancto Assunzione had to be re-fitted with the embedded electronics.
The Judicious, using technologies from the Type 089, is the first nuclear Etrurian submarine to operate the Audacia Combat Management System, which receives data from the boat's sensors and displays real time imagery on all command consoles. The submarines also have Aquia Hydrographic VARO 25 high-precision echosounders, two HHJ10 non-hull-penetrating optronic masts—in place of conventional periscopes—which carry thermal imaging and low-light TV and colour CCD TV sensors. The sensor suite performs surveillance, intelligence gathering, and electronic warfare, with a multispectral suite of a color and a monochrome high-definition TV cameras, a midwave infrared staring sensor and eye-safe laser rangefinder. Due to the non-penetrating hull nature of the mast system, more room in the control room has been used to expand the sonar command suite, furthermore the optronics feeds data straight to the Audacia Combat Management System, giving the crew complete real-time data, improving the submarine's combat awareness.
The Judicious class carry up to 24 T-740 Drago SLBMs, but can also carry smaller missiles with intermediate ranges due to the use of modular tubes which can be exchanged for wider or smaller diameter tubes. It's six torpedo tubes allow the submarine to operate T-10 Supercavitation Torpedo, Type 09 torpedo and the Model DT58 torpedo.
