3 Wessex Mk 60 (ex Bristow Helicopters) delivered with long range fuel tanks between 1991 and 1994 replacing ex USN SH-34Js
. Also some ex UK Royal Air Force HC.2 airframes, 2 ? in 1997, 5 in Feb 1998. Based at Curbelo AB in Laguna del Sauce on the southern tip of Uruguay.
Westland refused to support these aircraft (probably due to distance,
age, parts availability etc), and they are supported by Sikorsky. As
a result, they are known as Sikorsky S-58s, despite their
heritage as Wessex from a factory in the UK.
