Top 10 Destroyers

This is an attempt from us to find the most advanced destroyer in the world. It’s a pretty difficult task to find the best ones. The rankings based on the technology incorporated and the effectiveness in different war scenarios.

What’s a destroyer?

Destroyers are warships that provide multi-mission offensive and defensive capabilities. Destroyers can operate independently or as part of carrier strike groups, surface action groups, amphibious ready groups, and underway replenishment groups.  Many are equipped to carry out anti-submarine, anti-air, and anti-surface operations. The NATO standard designation for these vessels is DDG. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing, or dropping it altogether. Destroyers are among the widely used ships in the world due to their wide range of use. Their combination of high firepower and high endurance make them ideal for war, escort and (other) peace-keeping operations. The name “Destroyer” comes from the Russo-Japanese war in the early 20th century where they were named “Torpedo boat destroyer”. Today they are the heaviest surface combatants after the cruiser.

Each face of the array carries 2,500 gallium arsenide transmit and receive modules, with an output of 25kW. BAE Systems reconfigured Sampson to produce a near spherical design which retains the two arrays internally.
 
Modes of operation include long and medium-range search, surface search, high speed horizon search and high-angle search and track. Sampson uses digital adaptive beamforming which makes it highly resistant to electronic countermeasures. PAAMS uses a DCN Sylver A50 vertical launcher with eight cells. The Type 45 has six Sylver VLS.
 
Guns
 
Daring has MK8 4.5 inch medium gun. The 4.5in main gun, found on the forecastle of all the Royal Navy's frigates and destroyers, it is the most obvious provider of punch and firepower. The gun can fire up to two dozen high explosive shells, per minute, weighing more than 40kg (80lbs) at targets more than a dozen miles away - and nearly 18 miles if special extended-range shells are used.
 
The main purpose of the gun is Naval Gunfire Support – artillery bombardment of shore targets. In this role the gun is capable of firing the equivalent of a six-gun shore battery.
 
Sensors
 
The SAMPSON AESA and the S1850M long-range radars are the primary radar systems of Daring class. The Sampson multi-function Active Electronically Scanning Array (AESA) radar is two faces rotating radar enclosed in a spherical radome and placed high up in the mast. This radar has a range of around 400 km and can search and track hundreds of objects at once. As an active array, SAMPSON uses software to shape and direct its beam allowing several functions to be carried out at once and, through adaptive waveform control, is virtually immune to enemy jamming.
 
 S1850M radar is passive arrary radar operating at D band to provide Wide-area, long-range search. Raytheon Systems supplied the IFF (identification friend or foe) system. Type 45's surface ship torpedo defence (SSTD) system included the MFS- 7000 bow-mounted medium-frequency sonar. The system provides automatic warning of a torpedo attack and tactical advice on ship manoeuvres and the deployment of decoys to defeat the threat.

4) Sejong the great class (S.Korea)

The Sejong the Great-class destroyers also known as KD-III, are three guided missile destroyers of the Republic of Korea Navy (ROKN) which sought to provide the South Korean Navy with a world-class destroyer capable of meeting virtually any threat at sea, on land, or in the air. These are one of the most advanced warships afloat today. The design of these vessels borrows heavily from features of the American Arleigh Burke class and the Japanese Atago class, and shares numerous common components and systems as well. Apart from the longer hull, the overall design of KDX-III is identical to that of the Arleigh Burke Class destroyer. The KDX-III destroyers are the largest surface warships to carry the Aegis weapon system. One notable difference between the Sejong the Great-class ships and Burkes is the number of VLS cells. Destroyers of the Sejong the Great class will have a capacity of 128 missiles, as opposed to 96 on the Arleigh Burke class and the Japanese Atago class destroyers. And another difference between the Sejong the Great-class ships and Burkes and Atago class the Point-defense armaments which consist of Goalkeeper CIWS and a RIM-116 Rolling Airframe Missile. Land-attack capability for Sejong the Great class is provided by the recently-developed Hyunmoo IIIC (Guardian of the Northern Sky) cruise missile, which is similar to the U.S. Tomahawk.
The destroyer has an overall length of 165m, beam of 21m and draft of 6m. The standard displacement of the ship is 7,700t and full load displacement is 10,000t. The vessel can accommodate more than 300 crew members.
 
 
Command and control                        
 
KDX-III destroyers are equipped with the Aegis combat system developed by Lockheed Martin. The Aegis system consists of SPY-1 radar and other components including SPY-1D (V) transmitter and MK 99 fire control system. The radar acquires and tracks multiple targets such as aircraft and missiles. This system, integrated with the MK 41 vertical launching system, delivers missiles against multiple threats in different attack scenarios. It can be used as an integrated single ship system and in a ship-to-ship network.
 

The weapons, sensors, fire controls, propulsion, and other systems are fully-automated and networked together via the Aegis combat information system; the version currently used in the Sejong the Great class is Baseline 7 Phase 1. This system allows the ship to detect, identify, evaluate, and engage targets with no input from the crew, other than the decision to engage. The system can also display several-thousand contacts, and track and/or engage up to 100 simultaneously. It is also possible for the crew to operate these systems manually, as in earlier guided missile warships, without using the Aegis system. The class also has a Maritime Air Support Operation Centre (MASOC) system, allowing it to coordinate the operations of all friendly tactical aircraft in the vicinity.

South Korea was considering adding the SM-3 interceptor to its Sejong the Great-class ships to enable them to perform ballistic missile defense in response to North Korean efforts to bolster offensive missile capabilities

Weapons

The missile battery of the Sejong the Great class is exceptional; they carry an incredible 128 missiles in three different VLC launch cell pads second-place to the Kirov class battle cruisers.

It delivers engagement instructions to the WCS for the selection of weapons. The modern combat system defends against anti-ship missiles and also provides air defense, surface warfare (SUW) and anti-submarine warfare (ASW) capabilities to the vessel. The vessel can transfer combat data to other surface fleet units and aircraft through a data link and satellite.
Radar and sensors
 
The centerpiece of the 052D is the combination of Type 346 Dragon Eye (Type 346 radar has been frequently but erroneously confused with a Chinese fire control radar Type 348,  developed for Type 76 twin 37 mm naval gun as CIWS) active electronically scanned array radar system and Type 518 L-band radars . They are paired with the HQ-9B surface-to-air missile defense system. The HQ-9B is thought to have an effective range of about 200 kilometers. The Type 346A radar is S-band radar like the American SPY-1 radar. The Type 346 is multi-functional active phased array radar equipped with advanced area air defense capability. The radar system is intended to detect and track several hundreds of airborne targets such as fast jets and helicopters as well as surface threats such as fast speed boats and sea-skimming anti-ship missiles. It has a total of 3456 transceivers for searching and tracking, and a small 60 centimeters diameter C-band array with an approximate area of 0.3 square meters to control HHQ-9 SAM
 
A Russian expert claimed the Dragon Eye is capable of detecting the F-35, but there’s no firm evidence of that at this point. However,   Tactical stealth fighters are optimized to be undetectable from higher-frequency radar bands such the C, X, and Ku, but features like the tail-fin may make it susceptible to lower S or L-band frequencies. Depending on the distance between the ship and aircraft and the strength of the return of the omni-directional signal, a target may not be picked up at a tactically significant distance since L-band and most S-bands have resolution cells that cannot generate quality targets for weapons tracking. However, the SPY-1 and Air and Missile Defense Radar operate in higher frequency portions of the S-band and are able to generate weapons quality tracks, so Chinese systems could be similar. China is also speculated to be reducing the size of the large radar resolution cells by connecting multiple low-frequency radars through high-speed data-networks, which can refine resolution enough for tracking a missile to the target.
 
Type 518 radar is high performance L band long range radar. It can perform in adverse natural noise and active electronic jamming environments
 
Type 344 fire control radar is normally installed on top of the brigade right in front of the main mast. The radar is used as the standard fire-control radar for the 76m, 100mm, 130mm gun and anti-ship missile targeting. The system also includes a TV tracker and laser range finder.
 
Type 052 D also has an over the horizon radar. It has the ability to detect targets at very long ranges, typically hundreds to thousands of kilometers
 
Weapons

The Type 052D has a brand new vertical launching system (VLS) for surface-to-air missiles, cruise missiles, anti-submarine missiles, and anti-ship missiles, and is capable of quad-packing missiles.  The missile system uses a cold launch method to avoid flame and gas exhaust pipes on the hot launch VLS. It also reduces the damage caused to the vessel due to the blast communications one 32 cell unit mounted forward of the superstructure and one 32 cell unit mounted aft. The VLS system resembles the U.S. Mk41 VLS. Some sources states that 052 D utilizing an advanced method of hot launch called concentric canister launch.

YJ-18 anti-ship cruise missile is the primary weapon of 052D .it is a anti ship / land attack cruise missile. It is believed that the missile has a subsonic cruising speed of roughly Mach 0.8 and then before striking its target it enters a terminal stage of supersonic speeds of up to Mach 3, which makes it extremely hard to intercept. The YJ-18 has an effective range of 290 nautical miles, with a theoretical threat area of 264,200 square nautical miles. This missile reportedly has an inertial guidance system fed by the BeiDuo Satellite System. YJ 18 carries a 300 kg high-explosive warhead. It also has an anti-radiation warhead to destroy electronics at short range.
 
CJ-10 Land Attack Subsonic Cruise Missile, the range is believed to be more than 2000 km, it can a warhead of 500kg.  China claims this missile having a guidance package using inertial navigation system, satellite navigation, Terrain Contour Matching, and a likely Digital Scene-Mapping Area Correlator for terminal guidance.
 
 
CY-5 Anti Submarine missile, it has a range of 30 km.
 
1 x H/PJ-38 130mm deck gun.
2 x 30mm remote control guns
1 x H/PJ-12 CIWS
 
 
Propulsion

Two QC-280 gas turbine engines, each generates 28MW and two MTU 20V 956TB92 diesel engines, each generate 6 MW Combined diesel or gas (CODOG). Speed: 30+ knots.
 
Aviation
 
The helicopter hangar on the Type 052D is moved to the center, as opposed to being on the left like on the Type 052C. The ship has a single Harbin Z-9 helicopter.

2) Kolkata Class (India)

The Kolkata-class guided missile destroyers are the new stealth destroyers being built by Mazagon Dock Limited (MDL) for the Indian Navy, under Project 15A. . The vessel has an overall length of 163m, a beam of 17.4m and a draft of 6.5m With a standard displacement of 6,800 t (6,700 long tons; 7,500 short tons) and a full-load displacement of 7,400 t (7,300 long tons; 8,200 short tons), they are the largest destroyers ever operated by the Indian Navy. These are the first stealth destroyers being built by India and marked a significant development in India's shipbuilding technology.
 
Kolkata-class is a follow-on model of the Delhi-class.  Kolkata class share similar dimensions to Delhi class, however they have 2,363 modifications which include major upgrades in weaponry, sensors and helicopter systems. The propulsion system of the Delhi-class was also retained with minor upgrades. Most of the systems integrated in the ships are designed and built in India.
Kolkata class has a speed of 30 knots / 56Km/h and has a range of 8000 nautical miles/15000km at 18knots /33km/h. Kolkata class Destroyer is the most balanced on the planet it can perform any operation with equal effectiveness 

Command & Control
 
Kolkata class contains an advanced combat management system which uses all the sensors and radars and some specific equipment to give constant real time threat updates along with the analysis and the type of threat comes into one single place reducing the decision making time significantly. The system also advises the commanding officer about the kind of weaponry he should use to tackle the threat all this happens in real-time. The warship is equipped with a hi-tech operation theatre. It has a strong tactical data link. It can have voice, data and video transfer through intranet, use of satellite. The operation theatre too is so well-equipped that a surgery can be conducted onboard with the help of telemedicine and video conferencing.
 
The Ship is equipped with sophisticated digital networks, such as Asynchronous Transfer Mode based Integrated Ship Data Network (AISDN), Combat Management System (CMS), Automatic Power Management System (APMS) and Auxiliary Control System (ACS). The AISDN is the information highway on which data from all the sensors and weapon ride. The CMS is used to integrate information from other platforms using indigenous data-link system, to provide Maritime Domain Awareness. The intricate power supply management is done using APMS, and remote control and monitoring of machinery is achieved through the ACS. Kolkata class destroyers are also equipped with an action information system and an atmospheric control system.
  
Radar and sensors
 
The main primary radar of the ship is EL/M-2248 MF-STAR(Multi-Function Surveillance, Track And Guidance Radar) multi-mission AESA radar along with Thales LW-08 long range volume search radar and EL/M-2238 S-band STAR surveillance radar from Israel Aerospace Industries. This multifunction radar is mounted on top of the mast which allows for replacement of many other types of radar. It is said to be capable of guiding 24 missiles at the same time to hit 12 targets. This provides excellent air defence from high intensity missile attack. The MF-STAR is able to detect aerial objects >250 km and sea skimming subsonic cruise missiles at >25 km. It can detect a fighter aircraft flying at high altitude at ranges of up to 250 km. A low altitude incoming missile can be detected at ranges of up to 25 km. Overall, EL/M-2248 performance and appearance is similar to US Navy's AEGIS weapon system and its SPY-1D radar antenna.

The radar system is made up of 4 active arrays operating in the S-band, each of the 4 arrays is positioned in one direction. The radar employs multi-beam and pulse Doppler techniques as-well-as robust Electronic counter-countermeasures techniques to extract low radar cross-section targets from complex clutter and jamming environments. AESA radars provide a low probability of intercept of emitted signals and help the ships remain stealthy. Fiber optic cables replaced the waveguide and coax cables which substantially reduced its weight so it can be installed onboard small frigates or corvettes. MF-STAR can create multiple simultaneous beams in different directions. The technology of the radar array electronics is implemented in tiles laid in parallel to the array thus providing significantly reduced antenna weight.

The LW08 is a radar system for long-range surveillance, providing target indication to weapon control systems. It meets all vital requirements for any naval surveillance system. LW08 performs with great frequency agility over a wide band, due to its synthesizer-driven TWT transmitter.  Excellent performance under various clutter conditions is ensured by the wide dynamic range receiver with application of digital video processing, supported by circular polarization.  Moreover, due to its lightweight construction and hydraulically controlled stabilization platform, this antenna can be installed at a high mast position, thereby improving performance.
Sonar systems include HUMSA-NG (hull mounted sonar array - new generation) and Nagin active towed array sonar. HUMSA-NG is an advanced Active cum Passive integrated sonar system capable of simultaneous operation in active and passive modes. It is capable of detecting, localizing, classifying and tracking sub-surface targets in both active and passive modes.

The system provides simultaneous long-range detection in active and passive modes. The sonar is capable of localization and automatic tracking of up to eight targets in both active and passive modes.
The sonar integrates the operation of the UWT and XBT systems. The UWT functions are controlled from the main sonar console. The data received from the XBT is processed and presented on the workstation and also displayed on the sonar console. The sonar provides target classification facility with advanced classification features in passive mode of operation. The system is integrated with FCS systems such as IAC MOD ‘C and CAIO for exchange of relevant information. The sonar provides interface to the torpedo defence system to provide raw data for TD processing. Interfaces are also provided to obtain other ship house holding data such as course, speed, roll, pitch and GPS data
  
Weapons
 
The Supersonic Brahmos, is the primary offensive weapon in the Kolkata class destroyers. It is fitted into a 16 cell Universal Vertical Launcher Module (UVLM), which can be fired in salvo. There is enough deck space in Kolkata class to include more missiles ,  we should expect the 1000 km Nirbhay (or any other similar kind of) Cruise missile to be also fitted into the ships along with the Brahmos once its ready, giving it a powerful combination of cruise missiles.
 
The ship's main air-defence missile system has two 32-cell Vertical Launching System (VLS) which allows for up to a combination of 64 Barak 8 (medium-range) air-defence missiles and Barak 1 (short range) air-defence missiles. Barak – 8 has a range of 90+ Km and is actually quite nimble. Its minimum range is 0.8 km giving it the ability for point blank defense.

The main gun fitted forward is a 130mm gun. Four AK-630 close-in weapon systems (CIWS) are being provided for close-in air defense. The AK-630 CIWS can defend the ship from incoming anti-ship missiles and other guided weapons. It has a rate of fire of 5,000 rounds a minute.
 
The anti-submarine warfare is provided by twin-tube torpedo launchers and RBU- 6000 smerch-2 ASW rocket launchers. The rockets can be launched against submarines within a range of 6km.
 
The most distinctive and noticeable armament of the Kolkata class is its 76 mm (3.0 in) naval gun located forward of the bridge. The 76 mm gun provides limited anti-shipping capability and anti-air capability in addition to its naval gun fire-support role for land based operations.
 
For electronic warfare Kolkata class has Elbit Systems Deseaver MK-II decoy control and launching system. It protects the ship against anti-ship missiles coming from multiple directions. Apart from this ELLORA MK I electronic support measures , NSTL Maareech Advanced Torpedo Defence System,  Kavach chaff decoy system are also used to protect it from various threats.
 
Propulsion
 
The combined gas and gas (COGAG) propulsion system integrates twin Zorya M36E gas turbine plant. Four DT-59 reversible gas turbines drive the two propellers via two RG-54 gearboxes. The two KVM diesel motors are provided by Bergen and Garden Reach. Four Wartsila WCM-1000 generators and Kirloskar AC generators supply onboard electricity.
 
Aviation
 
Kolkata-class has a flight deck and enclosed hangar to embark up to two medium-lift helicopters such as HAL Dhruv advanced light helicopter (ALH) and AgustaWestland Sea King helicopter.

1) Zumwalt Class (USA)

Zumwalt-class destroyer is a class of United States Navy guided missile destroyers designed as multi-mission stealth ships with a focus on land attack. The Zumwalts displaces fourteen thousand tons, making them the largest U.S. Navy destroyers ever. The class has a low radar cross-section the 610-foot-long Zumwalt allegedly has a radar signature equivalent to a small fishing vessel, and a maximum speed of thirty knots. The class is multi-role and designed for surface warfare, anti-aircraft warfare, and naval gunfire support. The class is designed to require a smaller crew and be less expensive to operate than comparable warships. It has a wave-piercing tumblehome hull form whose sides slope inward above the waterline, which has been stated to reduce the radar cross-section (RCS) by returning much less energy than a conventional flare hull form. The acoustic signature is comparable to that of the Los Angeles-class submarines. Water sleeting along the sides, along with passive cool air induction in the mack reduces infrared signature
 
 
Command & Control
 
The combat system is based on the total ship computing environment (TSCE), utilising open architecture, standardised software and commercial-off-the-shelf (COTS) hardware. The Total Ship Computing Environment Infrastructure (TSCEI) is based on General Electric Fanuc Embedded Systems' PPC7A and PPC7D single-board computers running LynuxWorks' LynxOS RTOS. These are contained in 16 shock, vibration and electromagnetic protected Electronic Modular Enclosures. Zumwalt carries 16 pre-assembled IBM blade servers. The network allows a seamless integration of all on-board systems. Raytheon delivered more than six million lines of software for the DDG 1000 Zumwalt-class destroyer programme in January 2013. It also featured automated fire-fighting systems, automated piping rupture isolation etc.
 
The ship's Common Display System is nicknamed "keds": Sailors operate keds via trackballs and specialized button panels, with the option to interface by using touchscreens. The technology array allows sailors to monitor multiple weapons systems or sensors, saving manpower, and allowing it to be steered from the ops center.
 
 
Radar and sensors
 
The radar suite comprises dual-band radar for horizon and volume search, a Lockheed Martin S-band volume search radar (VSR) integrated with the AN/SPY-3 multifunction radar already being developed by Raytheon for the US Navy. The two radars are to be integrated at waveform level for enhanced surveillance and tracking capability.
 
The AN/SPY-3 multifunction radar (MFR) is an X-band active phased-array radar designed to detect low-observable anti-ship cruise missiles and support fire-control illumination for the ESSM and standard missiles.
The AN/SPY-3 Multi-Function Radar offers superior medium-to-high altitude search performance over previous radars, and can direct Standard SM-2 surface-to-air missiles.
 
The ship's Raytheon AN/SQQ-90 integrated undersea warfare system includes AN/SQS-60 hull-mounted mid frequency sonar, AN/SQS-61 hull-mounted high-frequency sonar and AN/SQR-20 multifunction towed array sonar and handling system. The dual-band sonar controlled by a highly automated computer system will be used to detect mines and submarines. It is claimed that it is superior to the Burke's sonar in littoral ASW, but less effective in blue water/deep sea areas. Although Zumwalt ships have an integrated suite of undersea sensors and a multi-function towed array, they are not equipped with onboard torpedo tubes, so they rely on their helicopters or ASROC missiles to destroy submarines that the sonar picks up
 
Weapons
 
The Zumwalt class has eighty vertical launch silos for launching SM-2 and Evolved Sea Sparrow Missiles, Tomahawk land attack missiles and ASROC anti-submarine rockets. It may someday include a railgun or free-electron lasers.
 
 
The ship’s proposed two 155-millimeter Advanced Gun Systems uses a Long-Range Land Attack Projectile, which have a range of up to eighty-three miles and a rate of fire of ten rounds per minute, have an anti-surface capability and would do tremendous damage against lightly armored surface ships of today [Rail gun](But the effectiveness of rail gun is questionable against moving ships cos of lack of guidance , probably the main objective of rail gun is to destroy land targets & railguns not installed yet, Us navy hopes to install in the 3rd Zumvalt class destroyer ).
 
Propulsion
 
Zumwalt is the first US Naval surface combatant to feature all-electric propulsion. The DDG 1000 integrates an all-electric drive with an integrated power system (IPS) consisting of two main turbine generators (MTG), two auxiliary turbine generators (ATG) and two 34.6MW advanced induction motors (AIM).
 
The electric drive eliminates the need for drive shaft and reduction gears and brings benefits in acoustic signature reduction, an increase in available power for weapon systems and improvements in the quality of life for crew. The all-electric propulsion of Zumwalt also generates 58MW of additional reserved power allowing the integration of future high-energy weapons and sensors.
 
Aviation
 
Zumvalt includes two landing spots for helicopters.
