New Russian Submarine is Stealthier Than a 'Black Hole'

The stealth capabilities of Russia’s new Lada-class diesel-electric submarines far exceed those of their predecessors, Admiraty Shipyard’s CEO Alexander Buzakov told the Russian press.

According to Buzakov, the new vessels are even stealthier than Russian Kilo-class submarines, thought to be one of the quietest diesel-electric submarine classes in the world and dubbed "black holes" for their ability to "disappear” from sonars.

The new submarines are able to maintain such a low profile thanks to a clever implementation of a next-generation anti-reflective acoustic coating and a new improved hydro-acoustic system, Buzakov said.

He also added that during the new submarines’ construction and design process, the development team managed to gather a lot of valuable data which, among other things, allowed them to significantly improve the Kilo-class submarines as well.

The Lada-class submarines are designed to defend coastlines against ships and other submarines, gather intelligence, provide surveillance and reconnaissance missions, and act as a mother ship for special forces. With its new air-independent propulsion plant, a Lada submarine can remain submerged for as many as 25 days. With its vast array of weapon systems, the Lada is also world’s first non-nuclear submarine to be equipped with specialized launchers for cruise missiles. (SputnikNews)

The difference between Lada and Kilo submarines

Although considered "ocean black holes" but in every opportunity Kilo almost increase in the number of Russian Navy and instead Lada submarines.

At present, Factory Admiralty in St.Petersburg was closed six 636.3 Varshavyanka class submarine (NATO Kilo) for the Black Sea Fleet. The vessel transfer will be completed by the plant in 2016..

Despite the ultra modern features but Kilo and Lada fate of Russia was determined. Accordingly, the Russian Kilo class submarines will be closed only to be used for export purposes, and Lada are closed only for domestic use. So what is the reason for this decision of Russia?

These reasons can answer for this decision:
First, Lada class submarines were designed as modular and series, it may be based on the requirement that the assembly of submarines with different loads as 550 tons, 750 tons, 950 tons, 1,450 tons, 1,650 tons and 1,850 tons.

In particular, from 1,650 tons or more types may installing missile chamber vertically and provide motivation system on subs do not depend on external air (AIP). But in general all kinds of Lada class submarines structured basically the same, the principle of operation is similar, therefore, very convenient for soldiers in combat synergistic.

Second, Lada class submarine technology application layer shell, reduces water relaxing than submarines of the same capacity. This is a very important factor, because it helps the submarine to become smaller, more flexible, especially in combat in shallow waters near the coast or warfare.

Third, the systems equipped Lada class submarine AIP helps reduce noise, improve operating continuously below the surface, thereby enhancing operational efficiency. Thus, in terms of stealth before the sound sensor, Lada class submarines even beyond Kilo class submarines, made famous as the "black hole of the ocean".

Fourth, Lada class submarine was equipped with modern equipment, automation, information and data to be exchanged and shared in the whole ship. This not only helps to shorten the order, but also reduce manpower. For example, Lada class submarines with 1,650 ton load of just 35 people, about half compared to conventional submarines have equal weight.

Fifth, Lada class submarines are equipped with vertical launch control makes weapons more diversified and more flexible. Besides, this system can also be used to launch frogmen or equipped to serve the special combat operations.

Sixth, Lada class submarines are equipped with hydroacoustic sensor type drag at the tail (towed array sonar) very modern, as well as help increase detection distances enemies. This equipment is very expensive, if not installed in Kilo class submarines, often can only be installed on a nuclear submarine or large anti-submarine ship. If you know that behind submarines often blind area exists for hydroacoustic sensors, people will see the importance of towed array sonar.

With 6 features emerging technologies mentioned above, most experts say the Lada class submarine design has reached a tipping point in the design of conventional submarine medium. (BaoDat)
