INS Kavaratti: What is our shadow warship playing blind bandage with enemy radar?

- 'INS Kavarti' is a floating example of modern technology to cover Indian waters with a veil of secrecy. About 90% of the ship's construction and technology is indigenous.

In World War II, Hitler's Nazi Germany launched a naval battle against Aiberton with battleship-type warships such as the Bismagark and the Tirpitz, which weighed 40,000 to 50,000 tons. Both ships were equipped with eight large and small cannons, some of which were capable of firing 15-inch warheads weighing up to 200 kilograms. If one or two such spheres had to go on the deck of an enemy ship, the ship would not survive without reaching the bottom of the sea. The iron bodies of 'Bismarck' and 'Tirpitz' are back like rhinos! German engineers anchored both battleships with a 12-inch thick iron band. As a result, the effect of enemy artillery shelling on that shield was like that of an ant biting an elephant.

The two battleships drowned so many British warships that the British navy worked hard to bring them to an end at any cost. On one occasion, a dozen British warships laid siege to Bismatark and rained down a barrage of artillery shells, but in vain! 'Bismalark' fired his lethal cannons against everyone alone. Eventually Britain sent its own fighter jets. British Air Force fighter jets conducted a number of flights, raining down numerous bombs and sending Bismarck and Tirpitz to the bottom of the sea. With the sinking of both ships came the era of battleship-type heavy, heavy warships. The nations of the world realized for the first time that ships like steel forts were helpless against aerial attacks.

After acquiring this knowledge, a new era of aircraft carriers came which fulfilled the need of an airport floating in the Mediterranean. The big advantage of the aircraft carrier was that the fighter planes flying from the runway of the deck rained death on the enemy ship. We got the benefit of this through 'INS Vikrant' during the Indo-Pak war of 191, from the deck of which the taken-off C-Hawk planes hit the targets of East Pakistan (present day Bangladesh).

The sun of the aircraft carrier in the maritime warfare has been burning for the last fifty years હજી and will probably remain at midday for years to come. Meanwhile, a parallel era has dawned in naval warfare: stealth / stainless technology. The technique of keeping an eye out despite being in front of the eye is called stahlth in English. Warships built with this technology cover the invisible veil of the secret. There are plenty of goddess staphylococcus type ships that do not reveal their presence by playing catch-up with enemy radar. Many nations of the world have begun to include such warships in their navies. This elite class also includes our country.

Twenty-five years ago today, we acquired state-of-the-art technology in collaboration with Russia and built the first ship at the beginning of the 21st century. Today, the Indian Navy has 18 stealth warships, one more added on October 4, 2020: INS Kavarti. (One of the islands of our Lakshadweep is called Kavaratti.) According to naval terms, it is a Corvette type ship. Experts have classified warships under different names, such as frigates, distro years, and cruisers, according to their size and function. A ship weighing 40,000 tons or more is called a battleship, while a warship weighing 5,000 tons or less is called a Corvette. However, the INS Kavarti made by Indian garden research ship builders Andy Engineers is overweight despite being a corvette. Engineers have weighed in at 2,500 tons. So it really should be counted as a lightweight frigate.

Of course, label it a corvette or a frigate. What's in a name? More important is work. 'INS Kavartti' does not seem to be working at all. The main operation of this stealth ship is to play against the submarines like predatory sharks floating in the sea. For this, in its arsenal is a Russian RBU-6000 type anti-submarine rocket launcher, from which twelve rockets can be fired simultaneously. Each rocket explodes with enormous explosions after reaching a few feet below sea level. The explosion creates such a tremendous pressure in the water that the enemy submarine's wreckage does not go unnoticed. The INS Kavaratti also has four torpedo tubes to submerge the submarine, from which a leopard-like DTA-53 type 8-foot-long torpedo rushes at a speed of 3 kilometers per hour.

Sea-King or Indigenous 'Pole' type helicopters are always deployed on the rear deck of 'INS Kavaratti' to locate the submarine floating on the water and give its exact address to the captain of the ship. The helicopter hovered in the sky while the sonar was submerged in the ocean, during which the sonar operator detected the submarine by making waves of sound.

The INS Kavaratti can hunt submarines under the sea, as well as enemy warships floating on the surface and enemy aircraft flying in the air. The biggest aspect that makes this ship invincible is its stealth / stealth technology, which keeps it afloat. Indian experts have used a number of tricks to give INS Kavarti a deceptive form of shaded corvette. There are many constructions on a conventional built warship such as a well pillar, front and rear cannon trail, missile launchers, radar plaque mast, officers cabin, etc. The construction of 'INS Kavarti' is not traditional. In today's modern houses, the structure of 'INS Kavaratti' is built in such a way that the furniture as well as the kitchen are made in a modular manner by attaching loose wooden boxes.

Engineers from Garden Research Shipbuilders have assembled a total of 12 'shells' of metal to form 'INS Kavaratti'. No part is curved. Because such a design cannot survive without appearing on the enemy's radar. The outer shell of this warship is like a flat wall. (See, drawing and drawing). The surface of each part is slightly sloping back, so the enemy's radar waves hit the surface and turn towards the sky instead of being reflected in the same way.

When the waves of radar flow hit the surface of a ship and return, they form a figure on the dial based on the waves. By looking at the diagram, the radar operator can find out which type of ship is a frigate, a destroyer, an aircraft carrier or a corvette floating hundreds of kilometers away. Here, 'INS Kavaratti' brings glare to the eyes of the enemy radar. In other words most of the radar gloves that turn towards the sky after hitting the surface do not reach the operator. If the amount of socks returning is negligible, then the figure formed on the radar based on them is not very good. The three hundred and fifty feet long 'INS Kavarti' appears on the dial of the enemy radar as a barely Visek feet long ship as shown in the drawing. It is possible that the operator, after seeing such a figure, assumes it to be a fishing boat.

Another feature of INS Kavarti lies in the material used in its upper structure, which is made of carbon-fiber. Low weight, but also immense strength is characteristic of carbon fiber. Therefore, it is used in the construction of two passenger aircraft such as Airbus-350, Airbus-380 and Boeing-787. Carbon-fiber radar reflects microwave waves nowhere less than metal. Many countries in the world make light wood sandwiches like balsa between two layers of carbon-fiber in the construction of stable warships. Since some radar waves absorb the balsa wood, there is no question of its reflection!

The third aspect that mirages 'INS Kavarti' against the enemy is the special type of paint applied on the surface. It absorbs the electrical energy of some of the radar microwaves and converts it into heat energy. Thus, they cannot be reversed as the microwave is self-transforming. All these aspects are enough to put dust in the eye of the radar, but often the enemy also conducts a search operation of the ship with infrared sensors. Such sensors detect the infrared rays of heat and detect the presence of a vessel on their basis. Of course, INS Kavarti also has a provision to prevent this. Experts from Garden Research Ship Builders have set up machines to spray cold seawater on the INS Kawartti to erase the heat generated by the engine (hence the infrared signature of the ship). Every now and then a drizzle comes out of it, so the overall structure of the ship stays cool. The presence of the ship is not captured in the enemy's infrared machines.

The 'INS Kavaratti' is a floating example of modern technology, covering a wide range of secrets to protect Indian waters. Knowing that about 90% of the ship's construction and technology are indigenous, one is proud of it and its builders. We are too late in domestic arms production. It's too late now, it's too late to be late. If other weapons like INS Kavaratti are Indianized and only then will the word self-reliance be meaningful in the field of defense.
