Project history

The need of a property designed OPV led to Naval Staff Target 7040 being prepared. Experience with the 'Island' class showed that more length would make for greater crew efficiency on extended patrol and enable the ship to have alternative roles. What had emerged was a substantial (but still cheap) ship which can been given a selection of weapons and sensors to meet customers' differing needs. In the RN version it was decided not to install a helicopter hangar, but to use the space instead to provide a bigger flight deck on which a Sea King can land and refuel if necessary. In wartime they could ship an OTO Melara 76mnvr62 compact.

Modernizations

early 1990s, both: - 1 x 1 - 40/60; + 1 x 1 - 30/75 DES-30B

Naval service

Both ships acted as dispatch vessels in the South Atlantic during the Falklands conflict, proof of their sea-keeping abilities.
