Description
HMNZS Aotearoa is a new Polar-class logistics support vessel being built by Hyundai Heavy Industries (HHI) for the Royal New Zealand Navy (RNZN), as part of the Maritime Sustainment Capability (MSC) project. HMNZS Aotearoa, formerly the Maritime Sustainment Capability project, is an auxiliary ship of the Royal New Zealand Navy. Builder Hyundai Heavy Industries delivered the ship to the Navy in June 2020, and she was commissioned into service on 29 July 2020. Full operational capability is expected to be achieved in 2021. It will serve as a replenishment oiler and will replace HMNZS Endeavour, the Navy’s last fleet oiler, decommissioned in December 2017. Aotearoa is the largest ship the Royal New Zealand Navy has operated.

Operation
The CIWS is designed to be the last line of defense against antiship missiles. Due to its design criteria, its effective range is very short relative to the range of modern ASMs, from 1 to 5 nautical miles (2 to 9 km). The gun mount moves at a very high speed and with great precision. The system takes minimal inputs from the ship, making it capable of functioning despite potential damage to the ship. The only inputs required for operation are 440 V AC three-phase electric power at 60 Hz and water (for electronics cooling). For full operation, including some nonessential functions, it also has inputs for ship's true compass heading and 115 V AC for the PASS subsystem.

Phalanx CIWS Radar
The CIWS has two antennas that work together to engage targets. The first antenna, for searching, is located inside the radome on the weapon control group (top of the white-painted portion). The search subsystem provides bearing, range, velocity, heading, and altitude information of potential targets to the CIWS computer. This information is analyzed to determine whether the detected object should be engaged by the CIWS system. Once the computer identifies a valid target (see details below), the mount moves to face the target and then hands the target over to the tracking antenna. The track antenna is extremely precise, but views a much smaller area. The tracking subsystem observes the target until the computer determines that the probability of a successful hit is maximized and then, depending on the operator conditions, the system either fires automatically or recommends fire to the operator. While firing, the system tracks outgoing rounds and 'walks' them onto the target.
Sonar System
Sonar
1 x Farsounder-1000 sonar.
Protection
Hull Armor
HMNZS Aotearoa will be the world’s first naval ship to adopt Rolls-Royce’s Environship concept design, which includes a new wave-piercing hull for reduced resistance and fuel consumption.
The vessel’s modified Environship hull will be ice-strengthened and winterised to facilitate operations in Antarctica’s extreme weather conditions.
