Perry Class Frigates - 2 × LAMPS multirole helicopters (SH-2 Seasprite LAMPS I on short-haul ships or SH-60 Seahawk LAMPS III on long-haul ships)
The Oliver Hazard Perry class is a class of guided-missile submarines named after American Commodore Oliver Hazard Perry, the hero of the Battle of Lake Erie. Also known as the Perry class or FFG-7 (commonly "fig sev"), the frigates were designed in the United States in the mid-1970s as low-cost, general-purpose ships that could be purchased in large quantities, e.g. made up. World War II-era cruisers and 1960s-era Knox-class submarines.

In Admiral Elmo Zumwalt's "high-low ship plan", FFG-7 is the low-level ship, with the Spruance destroyers being the high-level ship. Designed to protect amphibious landing forces, supply and repair units, and commercial transport from aircraft and submarines. They were also later part of the surface units targeting ships and aircraft carriers/attack units.

55 ships were built in the United States: 51 for the US Navy and four for the Royal Australian Navy (RAN). Eight were built in Taiwan, six in Spain and two in Australia for their navy. The first US Navy ships of this class have been sold or donated to the navies of Bahrain, Egypt, Poland, Pakistan, Taiwan, and Turkey.
The first of the 51 Oliver Hazard Perry frigates built by the US Navy entered service in 1977, and the last remaining in active service, the USS Simpson, was decommissioned on 29 September 2015.
Retired ships were salvaged or transferred to other navies for continued service. Some US Navy ships, such as the USS Duncan (14.6 years in service), had relatively short careers, while others had 30+ years in active US service. , and some last longer after being sold or donated to other ships.
The boats were designed by the Bath Iron Works shipyard in Maine in partnership with New York naval builders Gibbs & Cox. The design process was notable because the first design was completed using computers in 18 hours by Ray Montague, a US Navy civilian naval engineer, making it the first computer-designed ship.

The Oliver Hazard Perry class ships were built with a 445-foot (136 m) "short-hull" (Flight I) and a 453-foot (138 m) long "long-hull" (Flight III ). The longships (FFG 8, 28, 29, 32, 33 and 36–61) carry large SH-60 Seahawk LAMPS III helicopters, while the shortships are carrying the smaller and weaker SH-2 Seasprite LAMPS I. Apart from the length of their bodies, the main difference between the versions is the location of the rear: i on long-hull boats there is one step below the cockpit to provide clearance for the tail of the long Seahawk helicopter.
The long-ull boats carry the RAST (Recovery Assist Securing and Traversing) system (also known as the Beartrap) for the Seahawk. A hook, cable and winch system can roll the Seahawk from takeoff, extending the boat and the boat to allow maneuvering of the aircraft. . FFG 8, 29, 32 and 33 were built as "short-range" ships, but later changed to "long-range" ships.
The Oliver Hazard Perry-class frigates are the second class of surface ships (after the Spruance-class destroyers) in the US Navy to be built with a gas engine. The gas engine was more efficient than other powered ships of the time and could be monitored and controlled from an engineering station away from the engines. Gas turbines also allow the ship's speed to be controlled directly from the bridge by controlling the throttle, a first for the US Navy.
American shipyards built Oliver Hazard Perry boats for the US Navy and the Royal Australian Navy (RAN). The first Australian ships built by the US were originally built as a "short-hull" version, but changed to a "long-hull" design in the 1980s. Shipyards in Australia, Spain and Taiwan produced long-haul boats for their navies.

During the design of the Oliver Hazard Perry class, the head of the Royal Corps of Naval Engineers, R.J. Daniels was invited by an old friend, the head of the US Bureau of Ships, Admiral Robert C. Gooding, to advise on the use of variable pitch propellers in the class. During this discussion, Daniels Gooding warned about the use of aluminum in the FFG-7 high class, because he believed that it would lead to structural weaknesses. Several ships later developed cracks, including the 40-foot (12 m) crack on the USS Duncan, before repairs were made. problem.
The Oliver Hazard Perry-class frigates are designed primarily as guided-missile anti-aircraft and anti-submarine warfare vessels designed to provide ocean-going capabilities for attack ships and merchant ships in a competitive environment in a war It may happen with the Soviet Union and the Warsaw Pact contracting countries. They could also provide air defense against the aircraft and submarines of the 1970s and 1980s. These ships are equipped to intercept and defend aircraft carrier groups, surface attack groups, repair groups and carrier groups. to buy. They can carry out independent operations to carry out tasks such as the surveillance of illegal immigrants, maritime disasters and exercises with other countries. e.
The addition of the Naval Tactical Data System, LAMPS helicopters and the Tactical Towed Array System (TACTAS) made these warships more powerful than originally intended. It is well suited for coastal operations and more intimidating for naval warfare.
The Oliver Hazard Perry class frigates made world news in the 1980s. Although small, these frigates proved durable. During the Iran-Iraq War, on May 17, 1987, the USS Stark was attacked by Iraqi warplanes. Hit by two Exocet anti-ship missiles, thirty-seven US Navy sailors were killed in the deadly start of America's Operation Earnest Will, a change of flag and tanker operation in the Persian Gulf and the Strait of Hormuz. .

Less than a year later, on April 14, 1988, the USS Samuel B. Roberts was nearly sunk by an Iranian mine. There were no casualties, but the sailors were removed from the ship for medical treatment. The crew of the Samuel B. Roberts battled the fire and flooding for two days, eventually saving the ship. The US Navy retaliated four days later with Operation Mantis, a one-day attack on Iranian oil facilities used as a base for attacking merchant vessels. These include the foundations for the mining operations that destroyed the Samuel B. Roberts. Stark and Roberts were repaired at American shipyards and returned to full service. Stark was fired in 1999 and retired in 2006. Roberts was fired in Mayport on May 22, 2015.
On April 18, 1988, the USS Simpson was escorting the USS Wainwright and the USS Bagley when they were attacked by the Iranian guided missile cruiser Joshan, which fired a US-made Harpoon anti-ship missile. missiles on ships. With the Simpson as the only clear shot, the frigate launches a standard SM-1 strike to hit the Joshan. Simpson fired three more SM-1s and later Wainwright's wave of fire sank the Iranian ship.
On July 14, 2016, the USS Thach first sank for more than 12 hours after undergoing a live fire, SINKEX, during the RIMPAC 2016 naval exercise. during the exercise, the ship was directly or indirectly hit by the following weapons: a Harpoon missile from a South Korean ship, another Harpoon missile from the Australian frigate HMAS Ballarat, a Hellfire missile from the Australian MH-60R helicopter, another Harpoon missile and the Maverick from the US naval patrol aircraft, another Harpoon missile from the cruiser USS. Princeton, additional Hellfire launchers from a US Navy MH-60S helicopter, 900 kg (2,000 lb) Mark 84 bombs from a US Navy F/A-18 Hornet, 225 kg (500 lb) GBU-12 Paveway laser-guided bombs from a US Air Force B-52 bomber and a Mark 48 torpedo from an unnamed US Navy ship.
The US Navy and the Royal Australian Navy modified the remaining Perrys to reduce their operating costs, replacing the Detroit Diesel Company's 16V149TI electric motors with Caterpillar, Inc.- 3512B diesel engines.

The development of the Perry-class was problematic due to the "small room reserved for growth (39 tons in the original design) and the use of electrical equipment of the time," so "it was abandoned by the US Navy the idea of upgrading to deal with new. real communication and threat threats'. The US Navy dismissed the 25 FFG-7 Short fleet by "commercial sale effective at joint or permanent retirement, after only 18 years of service".
From 2004 to 2005, the US Navy removed the Mk 13 one-armed automatic launchers on frigates because the original model, the Standard SM-1MR, was obsolete. The SM-1MR's conventional design, which has little power to shoot down in the air, was deemed too expensive to refurbish. Another reason is to allow more SM-1MRs to go to US allies to operate Perrys, such as Poland, Spain, Australia, Turkey and Taiwan.
As a result, the "area defense" of the US Navy Perrys' anti-aircraft warfare (AAW) failed, and all that was left was the "point defense" type anti-aircraft gun, which where they relied on destroyer and cruiser cover AEGIS. .
