Deliria Vandaria Class Nuclear Submarine

Deliria Vandaria Guided Missile Nuclear Submarine.

Another improvement to the baseline Deliria Thalia, to give Deliria class "true" strategic reach.

She uses same basic hull and systems as Deliria Thalia. However diesel generators now gave up her place to advanced 170 MW Lead-Bismuth Cooled Nuclear Reactor and associated 34000 Kw 2 shaft Turbines. The boat now capable of maximum underwater speed of 44 Knot, similar to Russian project 661 Anchar (papa class submarine).

However this kind of speed may result with hull damage and total loss of acoustic sensor capability due to excessive hydrodynamic noise caused by flowing water around the submarine.

Armaments load is increased over other sub in Deliria family with provision of extra room by removal of uneeded battery equipment, allowing Vandaria to carry up to 32 Torpedoes.

The torpedo loading system is fully automatic and require very little man intervention. The torpedo stowing mechanism is work using electro hydraulic principles with redundant backup in case of main system failures.

Torpedo ejection system is using hydraulic and "swim out by itself" system, allowing topedo employment in deeper diving depth than typical conventional air pressure ejection system.

The backup torpedo launch system however is quite compact and easy to operate, the system use separate manually activated diesel generator, hydraulic piping and reservoir network.

However due to smaller capacity of the system. It only allows firing of four smaller 533 mm tubes, limiting use to self defense situation only.

Missile armaments are located in separate VLS system with compressed air system, limiting employment depth of the missile at max 50 m depth.

The missile tubes is capable to accommodate eight land attack cruise missiles in our arsenal, the early Natalya Melona and newer Natalya Vandaria, with range of 1500-3000 Km, this capability padded with silencing measures employed allow Vandaria to perform covert- surgical precision strike mission with little probability of enemy detection. Thus ensures high survivability of the boat and crew.

The ship also features more automations with advanced super computer systems and automated machineries, reducing crews to mere 14 (13 officers with 1 cook), the engine and armaments room is completely automated, with robotic servicing system and damage controls. Thus improving safety as the crew can now be concentrated on the center hull, near the escape hatch and capsule system.

Deliria Vandaria is a double hull type submarine where stronger titanium alloy made inner hull is completely enclosed by lighter hydrodynamic hull made of thinner non ferrous steel alloy. Between the hulls lies the various of submarine's tank systems , from Main Ballast Tank till the Trim and Compensation Tank.

There are also anechoic coatings to reduce acoustic emissions from the submarine's systems mainly the steam turbine gear and reactor coolant pumping system.

The space between the hulls also make place for submarine countermeasure launch tubes, such as gas bubble torpedo decoys which simulates noise of the sub.

The outer hull is layered with special rubber tiles to reduce detectability against active sonar and to reduce skin friction drag encountered during fully submerged condition.

In case of emergency Deliria Vandaria class is equipped with advanced crew escape system in shape of pod that capable of sustaining maximum diving pressure. Thus allowing escape to be made at essentially any depth.

The escape pod is provided with supplies and other equipments to sustain the escapees for around 2 weeks. Alongside the escape pod there are also smaller pod that contain liferaft which in case of emergency will also be deployed with the pod. Once it reached surface the pod will open up and releasing the liferaft.
