A RIM-66 Standard MR on an Mk-26 launcher
The Mark 13 is equipped to fire the RIM-66 Standard, RGM-84 Harpoon, and RIM-24 Tartar missiles for anti-air and anti-ship defense, and is capable of firing the Standard at a rate of one every eight seconds.
Its 40-round magazine consists of two concentric rings of vertically-stored missiles, 24 in the outer ring and 16 in the inner. In case of a fire, the system is equipped with magazine sprinkling,
CO2 suppression and booster suppression.

In the middle 1980s, the SM-2MR was deployed via Mk 41 Vertical Launch System (VLS) aboard the USS Bunker Hill, the first U.S. Navy ship to deploy a vertical launcher. VLS has, since 2003, been the only launcher used for the Standard missile in the U.S. Navy aboard Ticonderoga-class cruisers and Arleigh Burke-class destroyers.

In mid-2000, the Navy removed the frigates' Mk 13 single-arm missile launchers and magazines because the primary missile, the
Standard SM-1MR, became outmoded.
Note: As of 2004, Mk13 systems removed from all active US vessels of this class.

The "zone-defense" anti-aircraft warfare (AAW) capability has vanished, and all that remains is a "point-defense" type of AAW armament. It would supposedly have been too costly to refit the Standard Missile SM-1MR missiles, which had little ability to bring down sea-skimming missiles. Another reason is to allow more SM-1MRs to go to American allies that operate Perrys, such as Poland, Spain, Australia, Turkey, and the Republic of China (Taiwan).
The loss of the launchers also strips the frigates of their Harpoon anti-ship missiles. However, their Seahawk helicopters can carry the much shorter-range Penguin anti-ship missile.
