High Quality Content by WIKIPEDIA articles! HMS Kent (D12) was a batch-1 County-class destroyer of the Royal Navy. She and her sisters were equipped with the SeaSlug Mk-1 medium range surface to air missile SAM system, along with the short-range SeaCat SAM, two double mount 4.5" gun turrets, two single 20mm cannon, ASW torpedo tubes, and a platform and hanger that allowed her to operate one Wessex helicopter. The Counties were large ships, with good seakeeping abilities and long range, and were ideal blue-water ships for their time.
