The Royal New Zealand Navy is the maritime arm of the New Zealand Defence Force. The fleet currently consists of nine ships. The Navy had its origins in the Naval Defence Act 1913, and the subsequent acquisition of the cruiser HMS Philomel, which by 1921 had been moored in Auckland as a training ship. A slow buildup occurred during the interwar period, and then in December 1939 HMS Achilles fought alongside two other Royal Navy cruisers at the Battle of the River Plate against the German ship, Graf Spee.
The South African Navy (SA Navy) is the naval warfare branch of the South African National Defence Force.
A patrol boat is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine, estuarine, or river environments.

Project Protector was a Royal New Zealand Navy (RNZN) procurement project that was undertaken during the 2000s. At the start of the decade, the New Zealand government tasked the New Zealand Defence Force to develop an equal combat, peacekeeping, and disaster relief capability, in which the RNZN was to focus on conducting sealift operations and patrols of the Economic Exclusion Zone. A series of reviews found that the RNZN was lacking in these capabilities, and Project Protector was established to acquire three new ship types: a single multi-role sealift ship, two offshore patrol vessels, and four inshore patrol vessels. After a two-year information-gathering and tender process, an Australian company, Tenix Defence, was selected as the primary contractor.
