O míssil superfície-ar SM-1 Standard (RIM-66), que equipará as OHP, é supersónico.
The RIM-66/67 Standard missile were developed as the replacement for Terrier, Talos and Tartar surface-to-air missiles. It is an all-weather, supersonic, ship-launched, medium to long-range fleet air defense missile providing defense for an entire fleet area. There are 4 major types of Standard missiles: the SM-1, SM-2, SM-3 and SM-4. The SM-1 and SM-2 are air defense missiles, the SM-3 is intended exclusively against medium/long-range ballistic missiles and the SM-4 is a land attack missile.
The baseline Standard, the SM-1 model, was a semi-active radar guided missile while late models incorporate advanced signals processing, GPS, IR-guidance system as well as other refinements. The Standard missile is operational in frigates, destroyers and cruisers of 14 navies all over the world.
The First Standard missile was deployed by the US Navy in 1970.
The Standard SM-1 ER was deployed in 1981 featuring a booster for extended range and inertial navigation aids. The Standard SM-1 ER dramatically increases the range of the SM-1 MR missile providing long-range engagement capability to military ships. Raytheon still continues to provide support to the latest SM-1 model the Standard SM-1 Block VIB. The Standard SM-1 missiles are deployed aboard FFG-7 Oliver H. Perry class frigates.

Quanto à "João Belo", e tal e qual confirmou o nosso colega Nautilus, está tudo bem com ela. Continua a ser intenção da Armada somente desactivá-la e à "Sacadura Cabral" quando as duas OHP estiverem operacionais.
