What is the difference between Frigate and Destroyer

[AZADPAKISTAN2009]

What is the big difference and why Pakistan has no destroyers in its Navy -

I think if Pakistan get build 3-4 more frigates , and may be 3-4 destroyers the navy would be in better shape , and why can we at least - build a platform on the navy vesseles to lanch 4-5 helicopters from these vesseles ???

Mini Craft carriers etc ?? Loaded with some new fancy missiles I keep hearing about in papers? ??

Destroyers (DD or DDG)

A destroyer is currently the largest type of surface combatant currently under construction for world navies. Destroyers have steadily grown in size (now 5,000 to 10,000 tons), expense (nearly US$700 million apiece) and capability. Generally, a destroyer is considered to be a ship that has all of the sensors (including a sophisticated phased-array radar), combat systems, and weapons needed to operate in a high-threat environment. A number of world navies are currently building ships that, while called frigates, more accurately represent destroyers in size and capability. Examples include the Spanish F-100, the German F-124, and the Dutch De Zeven Provincien classes (all are highly capable ships displacing over 5,000 tons and carrying phased-array radars).

Frigates (FF or FFG)

A frigate is a medium-sized surface combatant (between 2,000 and 5,000 tons) that is either suited for one specific role (anti-submarine warfare or anti-air warfare), or has lesser all-around capabilities than a destroyer. A frigate may be less capable than a destroyer, but is still a relatively sophisticated and expensive (averaging around US$325 million apiece) platform. A frigate is generally the smallest surface combatant that can conduct extended blue-water missions in a high-threat environment.

Corvettes (FS)

Corvettes are fast (around 25 knots or better), well-armed ships that displace between 700 and 2000 tons. A corvette is generally not intended for extended ocean-going operations, and is best suited for regional operations. Corvettes are generally the smallest platforms capable of accommodating the sensors, weapons, and combat systems needed to operate in a medium threat environment. Corvettes are sometimes referred to as light frigates (FFLs). It can be assumed that the hull design for a corvette and that of an offshore patrol vessel are very similar. The differences will be in propulsion and outfitting. Corvettes will have higher speed and therefore less endurance and range than OPV, much greater armament, and less space for provisions and habitability.

AMI International - NSPD Sample

At 3,144 tonnes and considering its armement and sensor suite F22P is a Frigate, comparable to e.g. the Italian Lupo/Artigliere class, though the Type 53H3 (Jiangwei2) from which she derives displaces only 2,393 tons full load and with similar armement and sensors is considered a Light Frigate by many.

India has cleared its largest ever indigenous defence contract worth Rs 45,000 crore to manufacture seven advanced stealth frigates for the Navy at shipyards in Kolkata and Mumbai. The P17A warship project, which will be India’s most advanced and stealthy frigates, has been cleared by the Defence Acquisition Council (DAC) on Friday. Sources said that brushing aside a request by the Navy that two of the indigenously designed frigates may be manufactured abroad, the DAC has decided that all seven warships will be manufactured in India by the Mazagon Dock Limited, Mumbai (MDL) and the Garden Reach Shipbuilders and Engineers (GRSE), Kolkata. The Defence Ministry has allocated a budget of Rs 45,000 crore for the project and the work will be divided between the two shipyards. The P17A frigates will be even more advanced than the P17 Shivalik class warships that are currently being inducted by the Navy. This will also be the first time that the two shipyards will construct warships in the modern way of modular manufacturing. The frigates will be put together using 300-ton blocks that will be fitted together, similar to the construction style being used to manufacture the Indigenous Aircraft Carrier (IAC) in Kochi. This very concept of modular manufacturing had caused a divide between the Navy and the two shipyards with the former insisting that two ships be manufactured abroad so that Indian ship workers could absorb the required technology. In 2006, the Navy had even issued a Request for Information (RFI) ¿ a prerequisite to a tender ¿ to international ship manufacturers including French DCNS, Italian Fincantieri, American firms Lockheed Martin and Northrop Gruman besides shipyards in Russia and Korea to manufacture the frigates. However, the two Indian shipyards had stood firm on their stand that all the frigates could be manufactured indigenously and there was no need to outsource even one of the warships. One argument put forward was that it would not be wise to manufacture the ship abroad as it incorporated advanced indigenously developed stealth features. With the Defence Ministry taking the final call on the matter, the frigates will be manufactured in India and are expected to be inducted by 2021. The project is expected to start by 2011 when both GRSE and MDL complete an upgrade that will allow them to undertake modular construction. The first ship is expected to be delivered 3-4 years after work starts.

look at that how close israel and india are in few years time

India’s front-line warship INS Brahmaputra has arrived on a four-day goodwill visit to this northern coastal city to reaffirm old ties with Israel. “The visit shows the importance India attaches to its relationship with Israel. Not only that, it is also fitted with the ‘state-of-the-art’ Israeli Barak missile system as the first line of defence,” vessel commander Captain Philipose G. Pynumootil told a gathering on the ship. “The enthusiasm clearly shows that the Indian ship is in friendly waters. It is not only in Israel but a part of it is also Israeli,” India’s ambassador Navtej Sarna said, referring to the Barak system. Navy officials on board told PTI that Indian warships have regularly paid visits to ports in West Asia and East Africa reaffirming their peaceful presence and solidarity with countries in the region. Among the visitors was a former commander of the old INS Brahmaputra, Jack Japheth, now an Israeli citizen settled in Tel Aviv after retirement. INS Brahmaputra, one of the Indian Navy’s finest guided missile frigate, arrived here from Eritrea. It has a versatile suite of long range sensors, incorporating radars, sonars and electronic warfare equipment that enable her to simultaneously address threats in all three dimensions — surface, sub-surface and air.When needed, she can bring to bear awesome offensive or defensive fire power, with her wide-ranging top of the line ordnance.

Any news about Pakistan inducting Destroyers?

Don't know what you are counting but India has only 3 Delhi class destroyers and 5 (old) Rajput class destroyers = 8 rather than 15-20. Three new destroyers under construction will likely replace the oldest 3 Rajput class ships, which date from 1980, 1982 and 1983, while the newest two will remain in service for some time (they are slightly newer, dating from 1986 and 1988)

India currently operate 13 frigates and 8 corvettes (not counting Veer class, which is really a missile boat rather than a corvette). Of these, none are truly modern ship. And it should be considered that India has a far larger coastline to defend than Pakistan

3 more frigates on order from russia, 3 more frigates and 4 corvettes building in India. These are needed to replace older ships already paid off or that will be paying off in the foreseable future (e.g Nilgiri's)

But, to step back to the larger picture, why is it assuimed that because one country has a certain size and composition fleet that a likely opponent need also have a similarly sized and structured fleet? That assumes, for instance, a similar naval situation and strategy, which may entirely not be the case.

The size and composition of the PN fleet should be determined by its naval environment and strategy, not the opposing fleet. By carefull thought (proactive), not copying (reactive).

finally i got a post by you that i can fully agree with,,
no if's and but's but whtever you stated here was right on spot!!
the most importnat fact that should be kept in mind is that the indias have somewhat four time bigger coast line then ours to look after,,

Usually the size and the purpose. The period of time sometimes distinguishes the name.

Modern navy combat ships are generally divided into seven main categories. The categories are: Aircraft Carriers, Battleships, Cruisers, Destroyers, Frigates, Submarines, and Amphibious assault ships. There are also support and auxiliary ships, including the minesweeper, patrol boat, and tender. During the age of sail, the ship categories were divided into the ship of the line, frigate, and sloop-of-war.
Frigate is a name which has been used for several distinct types of warships at different times. It has referred to a variety of ship roles and sizes. From the 18th century, it referred to a ship smaller and faster than a ship-of-the-line, used for patrolling and escort work rather than fighting fleet actions. In modern military terminology, the definition of a frigate is a warship intended to protect other warships and merchant marine ships and as anti-submarine warfare (ASW) combatants for amphibious expeditionary forces, underway replenishment groups, and merchant convoys.

A corvette is a small, maneuverable, lightly armed warship, smaller than a frigate but larger than a coastal patrol craft.

In naval terminology, a destroyer is a fast and maneuverable yet long-endurance warship intended to escort larger vessels in a fleet or battle group and defend them against smaller, short-range attackers (originally torpedo boats, later submarines and aircraft).

A cruiser (From Dutch Kruiser, "something that crosses") is a classification of large warship. Historically they were generally considered the smallest ships capable of independent operations — destroyers usually requiring outside support such as tenders — but in modern parlance this difference has disappeared. In modern warfare the cruiser has virtually disappeared, supplanted in all roles by the destroyer.
In naval terminology, a destroyer is a fast and maneuverable yet long-endurance warship intended to escort larger vessels in a fleet or battle group and defend them against smaller, short-range attackers (originally torpedo boats, later submarines and aircraft).
At the beginning of the 21st century, destroyers are the heaviest surface combatant vessels in general use, with only four nations (the United States, Russia, France and Peru) operating cruisers and none operating battleships.[1] Modern destroyers are equivalent in tonnage but drastically superior in firepower to cruisers of the World War II era, capable of carrying nuclear missiles able to destroy cities in a very small volley.
Battleship was the name given to the most powerfully gun-armed and most heavily armored classes of warships built between the 15th and 20th centuries. Battleships evolved from northern European cogs, and included carracks and galleons in the 16th Century, ships of the line in the 17th and 18th centuries, broadside ironclads and Pre-Dreadnoughts in the 19th century, and Dreadnoughts in the 20th Century. For over 300 years battleships ruled the waves, allowing nations such as Portugal, the Netherlands, Spain, France and the United Kingdom to create and maintain trade-based overseas empires and restrain their rivals. During World War II (1939-45) they were superseded as the deciding factor at sea by aircraft carriers.

The surface fleet consists of many different types of ships, each contributing in their own unique ways to the success of the Navy as a whole. The abbreviation for each subtype of ship within each main type is written below.

• Cruisers (CG&CGN) protect the fleet from airborne threats by using their advanced AEGIS radars and anti-air missile systems, and also have the capability of striking targets ashore with their deck guns and long-range Tomahawk cruise missiles.In military terminology, a cruiser is a large warship capable of engaging multiple targets simultaneously. Modern United States Navy guided missile cruisers (CG and CGN hull classification symbols) perform primarily in a Battle Force role. These ships are multi-mission -- anti-aircraft (AAW), anti-submarine (ASW), and anti-surface (ASUW) surface combatants capable of supporting carrier battle groups, amphibious forces, or of operating independently and as flagships of surface action groups.


• Destroyers (DD/DDG) - protect the fleet from surface and submarine threats; many also have AEGIS, .These fast warships provide multi-mission offensive and defensive capabilities, and can operate independently or as part of carrier battle groups, surface action groups, amphibious ready groups, and underway replenishment groups.Guided missile destroyers are multi-mission [Anti-Air Warfare (AAW), Anti-Submarine Warfare (ASW), and Anti-Surface Warfare (ASUW)] surface combatants. The destroyer's armament has greatly expanded the role of the ship in strike warfare utilizing the MK-41 Vertical Launch System (VLS).

• Frigates (FFG) - small, tough convoy escort ships that provide anti-air and anti-submarine protection. Frigates fulfill a Protection of Shipping (POS) mission as Anti-Submarine Warfare (ASW) combatants for amphibious expeditionary forces, underway replenishment groups and merchant convoys.
The guided missile frigates (FFG) bring an anti-air warfare (AAW) capability to the frigate mission, but they have some limitations. Designed as cost efficient surface combatants, they lack the multi-mission capability necessary for modern surface combatants faced with multiple, high-technology threats. They also offer limited capacity for growth. Despite this, the FFG 7 class is a robust platform, capable of withstanding considerable damage. This "toughness" was aptly demonstrated when USS Samuel B. Roberts struck a mine and USS Stark was hit by two Exocet cruise missiles. In both cases the ships survived, were repaired and returned to the fleet

• Aircraft Carriers (CV/CVN) -Aircraft carriers provide a wide range of possible response for the National Command Authority.Home to over seventy aircraft, ranging from F35,F22 raptors, F/A-18 strike fighters and F-14 interceptors, to S-3B sub-hunters, EA-6B radar-jammers, and E-2C early-warning/command and control aircraft.
The Carrier Mission is:
- To provide a credible, sustainable, independent forward presence and conventional deterrence in peacetime,

- To operate as the cornerstone of joint/allied maritime expeditionary forces in times of crisis, and

- To operate and support aircraft attacks on enemies, protect friendly forces and engage in sustained independent operations in war.
The Nimitz-class carriers, nine operational and one under construction, are the largest warships in the world


• Amphibious Ships (LHA/LHD/LPD/LSD)
- carry up to 2,000 Marines, and their equipment, vehicles, and supplies. The Amphibious Assault subtype, or LHA's and LHD's, double as small aircraft carriers that are home to various kinds of helicopters and the Harrier vertical take-off and landing jet fighter. The LHA's, LHD's, and LSD's all carry modern, high-speed Landing Craft, Air-Cushion (LCAC) to ferry Marines and their gear ashore.

• Minesweepers (MCM/MHC/MCS) - detect and clear naval mines from areas in which other ships soon will be operating.

• Patrol Craft (PC) - small, speedy ships that patrol coastlines as well as insert and support SEAL special operations forces ashore.

• AuxiliarShips (AE/AOy /AOE/AS/ARS) - keep the fleet supplied with fuel, ammunition, food, and other crucial stores needed on long-term forward deployments.

Some answers from the Royal Navy FAQ page:

Question: What is the role of Frigates and Destroyers?
Answer: In wartime, the primary role of these ships is to protect friendly ships against attack. However Frigates and Destroyers are versatile multi-role ships capable of performing any number of tasks throughout the world, from humanitarian operations to anti-drug policing

Question: What is the difference between a Frigate and a Destroyer?
Answer: The primary role of a destroyer is to defend against airborne attack; by aircraft or missile. A frigate's primary task is to defend against submarine or surface threats.

Hi everybody. This is my first post. I have been an ardent follower of this forum and have come to appreciate all the information and knowledge that one can gain from this website.

Just an observation about one of the above posts. The Indian Navy now has 10 Destroyers (INS Kolkata & INS Kochi having been inducted into the Navy), and has another one of the same class in building. The number of frigates correctly stands at 13 with 6 more under construction.

Moreover, the Navy is undertaking a massive shipbuilding programme under which it has 35 ships and submarines under order to further its goal of becoming a true Blue Water Navy.

Cheers

perhaps the destroyer deserves a more detailed defination then this one, as far as i know, destroyers are more of a multirole platforms that are good at all forms of warfare ranging from Anti-air, anti-ship and anti-submarine mission whereas the frigates being smaller are usually dedicated to one of the above mentioned tasks. it can be either a anti-ship, anti-air or submarines hunter frigate. multi role frigates also exist but in this case they are not equally good in all roles as a destroyer can be!!
what do you think??

Kolkata and Kochi have yet to be fitted out, they are nowhere near active service. Which means 3 Delhi class destroyers + 5 Rajput class destroyers (of which only the newest pair will get modernized, and the oldest three will get replaced by Kolkata and het 2 sisters P15A)

And those 13 frigates include 4 very old Nilgiri class ships, with no SAM and no SSM, which will be paying off. Leaves 9 somehwat modern frigates: 3 modernized but nonetheless eldely Godavari class ships, 3 relatively new and modern Brahmaputra class and 3 Talwar class ships. Of the 6 frigates under construction, 4 will be replacements for the Nilgiris and 2 for the oldest Godavaris (which are about as old as the oldest Rajputs)

If there is mass building, then this is to replace exceedingly old units, many of which are not combat units, and not necessarily to expand the force.
