The Rothesay-class, or Type 12M frigates were a class of frigates serving with the Royal Navy, South African Navy (where they were called President-class frigates), Irish Navy and the Royal New Zealand Navy.
The original Type 12 frigates, the Whitby-class, were designed as first-rate ocean-going convoy escorts in light of experience gained during World War II. However, such were the capabilities and potential of the design that it was deemed suitable for use as a fast fleet anti-submarine warfare escort. As such, a repeat and improved Type 12 design was prepared, known as the Type 12M (M for "modified"), and known as the Rothesay-class after the lead ship. A total of nineteen vessels were constructed, with the lead ship being laid down in 1956, two years after the last Whitby.
