By Rajesh MishraThe Cobra Marine engine is the mainstay of naval vessels.
It was developed by British Naval Research and Development Laboratory in England in the early 20th century and has a very high fuel consumption, but it is also very reliable.
In a recent article, Naval Times reports that the Indian Navy is planning to start testing the engine next month on a Scorpene-class submarine, as part of the Indian Scorpene naval exercise.
The Cobra engine is one of the most fuel-efficient engines in the world.
In the US, it consumes 2.3 litres of fuel per kilometre, while the UK consumes 2,500 litres per kilometer, according to figures compiled by the UK Department of Energy and Climate Change.
The engines are a big part of a naval submarine fleet.
As it is designed for underwater operations, it is fitted with several different types of thrusters, such as those for the propellers, which help keep the vessel afloat.
The engines are also used for the propulsion system.
The most fuel efficient engines are those built in England.
The Cobra Marine engines are in a class of their own.
In fact, the Indian Naval Research & Development Laboratory was also the first to develop an engine in India.
The Scorpene class submarine is the newest class of Indian Navy vessels, and the Scorpene is an all-weather (weather, water and electromagnetic) submarine, capable of underwater operations and also has stealth capability.
The Navy has said that the Scorpenes are expected to be operational by the end of this year.
The Scorpene can carry around 40,000 tonnes of water, and has an underwater endurance of 2,400 hours.
