RBNS Sabha (90) is an Oliver Hazard Perry-class frigate in service with the Royal Bahrain Naval Force. The ship was former United States Navy frigate USS Jack Williams (FFG-24). The frigate is now considered as the lead frigate of the Royal Bahrain Naval Force.

The Oliver Hazard Perry class is a class of guided-missile frigates named after U.S. Commodore Oliver Hazard Perry, a commander noted for his role in the Battle of Lake Erie. Also known as the Perry or FFG-7 class, the warships were designed in the United States in the mid-1970s as general-purpose escort vessels inexpensive enough to be bought in large numbers to replace World War II-era destroyers and complement 1960s-era Knox-class frigates.
