Removed from the U.S. Navy ships starting in 2003, due to the retirement of the SM-1 missile from American service Two triple Mark 32 Anti-submarine warfare torpedo tubes with Mark 46 or Mark 50 anti-submarine warfare torpedoes One OTO Melara 76 mm/62 caliber naval gun One 20 mm Phalanx CIWS rapid-fire cannon Eight Hsiung Feng II SSM or four HF-2 and 4 HF-3 supersonic AShM, plus 2 Bofors 40mm/L70 guns on Taiwanese vessels only) |
| Aircraft carried: | Two LAMPS multi-purpose helicopters (the SH-2 Seasprite LAMPS I on the short-hulled ships or the SH-60 Seahawk LAMPS III on the long-hulled ships) |
It would supposedly be too costly to refit the Standard Missile SM-1MR missiles, which had a marginal ability to bring down sea-skimming missiles. Another reason for withdrawing the SM-1MR from the American ships is to focus the supplies of these missiles to American allies, such as Poland, Spain, Australia, Turkey, and the Republic of China (Taiwan), which need them most. (Possessing no or few other guided-missile warships in their navies.)
With the removal of their Mk 13 missile launchers the American Oliver Hazard Perry-class warships also lose their Harpoon anti-ship missile capability. However, their Seahawk helicopters can carry the much shorter-ranged Penguin anti-ship missile, delivered far from the ship by helicopter. The "zone-defense" anti-aircraft warfare (AAW) capability has vanished, and all that remains is a "point-defense" type of AAW armament.
The U.S. Navy plans to update the Oliver Hazard Perry-class warships' Phalanx CIWS to the "Block 1B" capability, which will allow the Mk 15 20 mm Phalanx gun to shoot at fast-moving surface craft and helicopters. The remaining Oliver Hazard Perry-class ships are also to be fitted with the Mk 53 DLS "Nulka" missile decoy system, which will be better than the presently-equipped chaff (SRBOC, Super Rapid Blooming Offboard Chaff) and flares at guarding against anti-ship missiles.
On June 16, 2009, Vice Adm. Barry McCullough turned down the suggestion of Mel Martinez to keep the Perrys in service, citing their worn out and maxed out condition.
