New Zealand's naval capacity is being enhanced through a training programme involving HMNZS Otago, one of the country's two offshore patrol vessels.
Otago is completing first of class flight trials, enabling helicopters to land on deck while the ship is in operation at sea.
Last month, Otago crew conducted the sea phase of trials in which an SH-2G Seasprite helicopter completed 161 landings and takeoffs from the ship.
Conditions varied to give crew practice at night, in rough weather and during simulated emergencies.
The flight trials were hailed as a milestone by the Royal New Zealand Navy (RNZN).
Ship and helicopter operating limits were established for the first time, which meant offshore patrol vessels could conduct embarked operations with the Seasprite.
Primary roles for Otago include fisheries and border protection, patrols and maritime search and rescue, which could be completed more effectively with a helicopter.
Chief of Navy, Rear-admiral Tony Parr, said operating helicopters from ships at sea was one of the most challenging activities any navy could undertake.
"We have been flying helicopters from frigates for many years, but now we are learning how to operate these aircraft from a different ship with different characteristics.
"Although it will be some time before the full potential is released, the navy can now begin helicopter operations during which time we will continue to learn and develop our capability," he told the RNZN's Navy Today.
Trials proved the Seasprite was able to conduct an airborne surveillance task from Otago for more than two hours, enabling more than 8300sq km to be covered in a single trip.
R-adm Parr said the operation of aircraft from Otago on actual deployments would further improve and streamline the procedure.
