   Some frigates are highly specialized and advanced, capable of performing one or more roles with extreme precision. Other frigates are simple, general-purpose vessels. They can be used for a wide variety of uses—anti-aircraft, Anti-Submarine Warfare (ASW), anti-ship, etc. The Oliver Hazard Perry class belongs to this group of general purpose frigates.

   This class was designed in the 1970s to replace the large numbers of obsolete US World War II and post-World War II general-purpose vessels, such as the Knox class ocean escort frigates. Something cheap, easy to produce, and of moderate general-purpose capabilities was required. And in the Oliver Hazard Perry class, the United States Navy got it.

   Anti-air capability of the Oliver Hazard Perry class mostly comes from a single Mk.13 launcher. This launcher is rather old-fashioned, for, instead of being a modern Vertical Launch System (VLS) where the missiles are launched quickly from flat, many-tubed launchers in the deck, the Mk.13 is a single-armed (and therefore slow firing) launcher that sticks up from the deck, increasing radar return and reducing stealth. Magazine of the Mk.13 can hold up to 40 missiles—either SM-1MR Standard surface-to-air missiles or AGM-84 Harpoon anti-ship missiles.

   The surface armament is small, but nonetheless moderately capable. For long-range combat, the Mk.13 launcher fires AGM-84 Harpoon anti-ship missiles. Located amidships, the OTO Melara Mk.75 76-mm gun, capable of firing its 6 kg rounds out to a maximum range of 16 kilometers, engages targets for medium range combat. The Italian gun was selected as superior to the US Navy's standard 127-mm/L54 gun in the medium/short-range air defense role.

   The ASW armament is composed of two triple Mk.32 torpedo tubes, firing the Mk.46 or Mk.50 torpedoes; two LAMPS helicopters (which carry their own torpedoes and sonar); and two types of sonar—SQS-56 (active) and SQR-19 (passive), which is a towed sonar. The two torpedo types are used with both the torpedo tubes and the helicopter. The Mk.46 has a range of 11 km, speed of 40 knots, and a 44-kilogram warhead. The Mk.50, on the other hand, has a range of 15 km, speed of 50 knots, and a 45-kilogram warhead.  Although the hull sonar is the SQS-56 short-range unit, the primary anti-submarine sonar is the SQR-19 towed-array sonar.

   For close range last ditch defense, a single 20-mm Phalanx Close-In Weapons System (CIWS) is also equipped. It can fire at 4 500 rounds per minute up to ranges of 1.5 kilometers. This weapon is also useful against other threats, such as small surface craft. Lastly, the close range unit is made up of four 12.7-mm (.50) M2HB heavy machine guns. Some warships of the Oliver Hazard Perry class have been modified and fitted with 25-mm Mk.38 cannons in place of the Mk.13 missile launcher.

   Many of the early ships of this class (shorter LAMPS I ships) operate a pair of SH-2 helicopters. Although newer ships (LAMPS III) are longer, and can therefore use the more capable SH-60 series helicopters.

   The ships have aluminium armour over their magazines, steel over the machinery, and Kevlar    plastic amour over their vital electronic and command facilities. There are two auxiliary 325-shp motor/propeller units to bring the ship home at 6 knots if it loses its main power.

   Fifty-one units of the Oliver Hazard Perry class frigates entered US Navy service starting in 1977. At its peak it was numerically the largest warship class in the US Navy. At the beginning of the 21st century the US Navy used 33 of these ships. At that time many were already retired or transferred to US allies. Recently the US Navy has completely removed the Oliver Hazard Perry class from service in favor of the new littoral combat ships, the Freedom class and the Independence class. The last vessel of this class was decommissioned from the US Navy service in 2015. Some of these ships were scrapped, while some are on hold for foreign military sales.

   Australia purchased six (known as Adelaide class)—four were built in America and two in Australia. Taiwan purchased two (to go along with their eight Taiwan-built Cheng Kung class ships). Spain has built six Santa Maria class ships. The United States also sold or transferred many Oliver Hazard Perry class ships to its allies --- one to Bahrain, four to Egypt, six to Pakistan, eight to Turkey, two to Thailand, and two to Poland. So, overall, the Oliver Hazard Perry class has entered into rather widespread service, although many of these ships have now been extensively modified or taken out of service altogether.

   The Oliver Hazard Perry class has seen some combat. In 1987, it gained international notoriety when the USS Stark was heavily damaged by two Exocet anti-ship missiles. It showed up once more in 1988, when the USS Samuel B. Roberts was damaged by an Iranian mine, though with no loss of life. The only successful action was later in 1988. The USS Simpson avoided a Harpoon missile attack from an Iranian gunboat and later sank it with its SM-1MR missiles and gunfire from supporting ships.

   The US Navy performed a number of modifications before eventually discarding the ships. These include the removal of the Mk.13 launcher (since the missiles it fired were outdated), the addition of 25-mm Mk.38 cannons in place of the Mk.13, and the addition of improved decoys.

   The Oliver Hazard Perry class frigate would costs about $720 million, considering adjust for inflation.

 

Variants

 

   G-class: the Turkish service version. They have been extensively modified. Modifications include advanced tracking systems, a Mk.41 8-cell Vertical Launch System (VLS) for 32 RIM-162 Evolved Sea Sparrow missiles, and improved sonar.

   Adelaide class: the Australian produced version. They have been heavily modified, including the addition of a Mk.41 8-cell VLS for 32 RIM-162 Evolved Sea Sparrow missiles and the capability to use different helicopters, such as the S-70B and AS350B. Six of these frigates were built.

   Santa Maria class: the Spanish produced version. Six of these vessels were locally built in Spain, including Santa Maria, Victoria Numancia, Reina Sofia (ex-America), Navarra and Canarias.

   Cheng Kung class: the Taiwan produced version. Modifications include the addition of two 40-millimeter Bofors cannons and the replacement of the Harpoon missiles with indigenous ones. Eight of these ships were built.
