The Type 14 Blackwood class were a ship class of minimal "second-rate" anti-submarine warfare frigates. Built for the Royal Navy during the 1950s at a time of increasing threat from the Soviet Union's submarine fleet, they served until the late 1970s. Twelve ships of this class served with the Royal Navy and a further three were built for the Indian Navy.
