What did Type 12 frigates offer the Royal Navy and foreign operators from the late 1960s onward?
Short answerA reliable, capable platform that could be modified to suit individual navies, even if it was not the most upgradeable design.
NotesThe Type 12 family was dependable rather than universally best in class. The frigates delivered a useful package of capability without depending on one exceptional specification. Their durable advantage was a sound platform that different operators could modify for their own requirements. That combination of reliability and adaptability helps explain why variants remained useful in foreign service long after their Royal Navy origins.
