Russia helped India build a destroyer
March 19, 2018
Visacaptam ... Viscatham ... In general, it does not matter. Destroyer with the onboard number D66, the head ship of the type 15-Bravo of the naval forces of India. The year of the launch is 2013, the launch on 2015, the commissioning is expected in 2018.
INS Visakhapatnam was designed by the Office of Naval Research of India with the participation of specialists from the Northern Design Bureau (St. Petersburg).
Power plant - gas turbine, combined, type COGAG - two independent turbines for each propeller shaft. The ability to disable one of the turbines on the economic path improves fuel efficiency (since at full load the efficiency of the gas turbine is higher than in the 50% power mode). Two M36E units (4 gas turbines, two reducers) manufactured by Zorya-Mashproekt (Ukraine) are used as the main engines.
The shafts of the propeller shafts are made at the Baltic plant (St. Petersburg).
As part of auxiliary power equipment, diesel engines manufactured by Bergen-KVM (Norway) are used; four "Wärtsilä" generator sets WCM-1000 (Finland) driven by Cummins diesel engines KTA50G3 (USA).
The hull of the ship is made at the shipyard "Mazagon Dock Limited" (Mumbai).
The most notable innovation of the type 15B destroyer is its network centric BIUS, which allows for high situational awareness for each combat post. In addition to the basic functions of the combat control system (analysis of incoming information, classification and assignment of priorities, selection and preparation of weapons), the new version provides automatic distribution of energy between the ship's systems.
The Israeli IAI "Elta", with the limited participation of Indian specialists (Bharat Electronics) and the well-known European company "Thales Groups", was engaged in the creation of the radar complex and detection facilities for the Indian destroyer.

The Israelis offered a multifunctional radar EL / M-2248 MF-STAR for the review of airspace and control of missile weapons. According to the developer, the use of active phased antennas improves the effectiveness of the MF-STAR radar when detecting low-noticeable targets in a complicated interference situation. To counter the radio interception systems, LPI (low probability of signal interception) technology is used, in which the learning frequency is tuned 1000 times per second. In addition to the basic functions, the radar can be used to adjust the artillery fire by bursts from falling projectiles.
The manufacturer pays attention to the small mass of the radar - consisting of four AFAR antenna posts together with the below deck equipment weighs only about 7 tons.
The only controversial aspect of the Israeli radar is its operating range (decimeter waves, S-band). This allowed to increase the detection range and eliminate the influence of weather conditions, in comparison with similar systems operating in the centimeter wave band (APAR, SAMPSON, OPS-50). But, proceeding from the world practice, such a decision should negatively affect the accuracy of accompanying high-speed small-sized targets.Perhaps, the specialists of "Elta" managed to partially solve the problem by means of software algorithms for signal processing.
The presence of a Thales LW-08 two-coordinate radar with a horn radiator and a parabolic reflector on the destroyer of the 21st century can cause surprise. In my opinion, the only reason for the appearance of LW-08 is its manufacturer - the company Bharat Electronics, which produces under license samples of European systems of the past generation.
Perfectly perfect for its time (1980s), the system is used as a backup radar in tandem with the multifunctional Israeli MF-STAR. The specified operating range D is an out-of-date designation for the decimeter range with wavelengths of 15-30 cm.
The key component of the destroyer's antiaircraft weaponry was the Israeli medium-long-range Barak-8 (Lightning-8) medium-range missile system capable of hitting air targets at ranges up to 70 km (some sources indicate a value of 100 km), in the altitude range from 0 to 16 000 m. Among the advantages - an active GOS, operating in the radio wave and thermal spectra (auxiliary IR-mode guidance for targets with small EPR).

The complex is notable for its compactness (the starting mass of the missile is 275 kg), the storage and launching of the missile ammunition is made from the UVP. Among other advantages: a combat unit (60 kg), quite powerful for such a light-weight missile. Presence of a controlled thrust vector. The missile is equipped with a two-stroke engine, which makes it possible to realize the most profitable trajectories during flight to targets at different distances; and also to develop a high speed when approaching the target.
The most significant drawback of Bark missiles remains the low flight speed (2M) - five times slower than the domestic missile systems Fort. Partly, this problem is compensated by the possibility of re-engaging the solid propellant at the final section of the trajectory.
Another unpleasant feature is the launch from a specialized UVP, which forces two types of launchers, without the possibility of unification and its use for other types of munitions (Mk.41, European Sylver). However, if there is enough space on the ship, this problem recedes into the background.
A total of 32 launching cells for anti-aircraft missiles are provided on board the Indian destroyer.
The total cost of four sets of shipborne antiaircraft missile systems for constructing destroyers of type 15B was, according to official data, 630 million dollars (2017), a very moderate amount against the background of global trends.
If we do not take into account the personal interests of the responsible persons, the choice of Barak-8 as the main air defense means of the Indian fleet is dictated by the compactness and relatively low cost of the complex (at the cost of deteriorating the power capabilities of the missile defense system and limiting the range of interception). Barak-8 is a reasonable compromise, allowing to get capabilities close to the best systems of shipborne air defense / long-range missile defense, at much lower costs.
The destroyer's attack weapons include two modules (16 OHR) for launching two types of cruise missiles: long-range missiles Nirbhay ("Fearless", the Indian analogue of "Caliber") for striking ground targets at a range of 1000+ km, and "three-mahog" supersonic RCPs type PJ-10 BrahMos (Bakhmaputra-Moscow, a joint development based on the P-800 Onyx).
Taking into account the high characteristics of the BKR Brahmos (speed at low altitude 2.5 M +) and the number of missiles, the Indian destroyer in the anti-ship configuration (all 16 mines occupied by the RCC) outperforms all existing types of ships in shock. even rocket cruisers of the Soviet model.
Of course, this estimate does not correspond to the actual combat situation. All these are technical notes handed over for a sober assessment of the threats emanating from the Indian "missile carrier".
The destroyer is equipped with a set of classic antisubmarine weapons of various generations, the real effectiveness of which is difficult to assess. The presence on board of two anti-submarine / multipurpose helicopters (such as Sea King or HAL Dhruv) extends the boundaries of the zone of the PLO. On the other hand, the absence of missile torpedoes and the questionable characteristics of the ASG do not give confidence in the fight against modern submarines.
The destroyer is equipped with the sonar of the Indian company Bharat Electronics. Obviously, we are not talking about an undercover SSA, because in the images presented at the time of launching, there is no characteristic "drop" (a massive radar cowl in the bow of the destroyer). The presence of a towed low-frequency antenna is also not reported.

For the destruction of submarines in the near zone are provided self-guided torpedoes of caliber 533 mm and two out-of-date RBU-6000. The presence of the latter is only a given to the traditions. Bombs (even jet) are completely ineffective in modern conditions. The only more or less realistic purpose is the destruction with their help of the detected torpedoes. This task also contains a lot of unknowns; To counter the torpedo threat, it is more useful to use various tow traps.
By the way, about the traps. The destroyer is equipped with a complex of production of passive jamming "Kavach" of its own Indian development. Kavach rockets can create veils from radio-reflecting particles at ranges up to 7 nautical miles.
Artillery. The destroyer is equipped with a 127-mm universal installation - a modern development of OTO Melara, also installed on European destroyers and frigates. The length of the barrel is 64 calibers. The range of fire can reach 30 km. Fully automatic system with a firing rate of 30+ rds / min.
The reason why the system data is still used in the fleet remains unclear. Too little power in 5 "shells to defeat any possible targets. On the other hand, 17 tons is a small price for the opportunity to make a warning shot under the nose of the intruder vessel. Or finish off the "podranok", making 150 cannons of mercy from the cannon.
For defense in the near zone, two batteries are provided - each consisting of two six-barrel AK-630s and a fire control radar. It is noteworthy that, unlike the US Navy, Indians do not save on such things. Or not yet fully realized the horror of the situation. Shoot down missiles near the ship - you can, but it's too late. In real combat, the benefit of any quick-firing cannon ("Phalanx", "Goalkeeper", etc.) remains questionable - fragments of downed missiles, one way or another, reach and damage ships.
Structurally, INS Visakhapatnam and three of its colleagues continue the ideas laid down in the destroyers of the previous type of Calcutta (accepted into the fleet in 2014-2016), differing from them with enhanced armament and more modern stuffing.
The technical level of destroyers of the Indian Navy has not yet reached the favorites - first-class destroyers of the United Kingdom, the United States and Japan. And the presence of a dozen foreign contractors does not contribute to an increase in combat capability in the event of a deterioration in the international situation. And it only points to the weakness of the Indian military-industrial complex.
At the same time, the Indians managed to build one of the most interesting destroyers in its class (7000 tons), different from the American concept of the "Burke" adopted for the standard. Weaknesses of the project are leveled by its impressive anti-ship weapon. Unlike most fleets, the Indians build ships not to release a couple of missiles over ruins in the desert.
In the creation of the destroyer of the type 15-Bravo, Russian specialists also took part, who gained experience in the design of modern combat ships. Experience is what we get when we do not get what we want. To our Navy, such ships would also come in handy.
Good quote. The primary goal of the Indian navy is to take on other advanced navies (though one opponent won't be so advanced). For that role, 16 Brahmos missiles and 32 Barak 8 missiles are perfect. I don't see any scenario where the Indian navy will be unleashing hundreds of Nirbhay missiles at some city. But we should build bigger destroyers with longer range air defence systems and additional nirbhay missiles that won't compete for the same VLS space with Brahmos.
