Patrol boat in the context of "Cyprus Navy"

Te Kukupa II is a Guardian-class patrol boat built in Australia for the Cook Islands. It replaced the original Te Kukupa, supplied to the Cook Islands three decades earlier. Her crew is drawn from the Cook Islands Police Service.

At the farewell of Te Kukupa I, Australian High Commissioner Christopher Watkins noted the original Te Kukupa had been a gift from Australia at a time when Australia and the Cook Islands "were united in our anger at French nuclear testing." Rather than Australia expanding its own Navy, the Hawke Government had decided to empower its Pacific partners. “We would trust that the stronger and safer our Pacific partners were, the stronger and safer Australia would be."

Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles. The term amphibious first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.

Amphibious warfare includes operations defined by their type, purpose, scale and means of execution. In the British Empire at the time these were called combined operations which were defined as "...operations where naval, military or air forces in any combination are co-operating with each other, working independently under their respective commanders, but with a common strategic object." All armed forces that employ troops with special training and equipment for conducting landings from naval vessels to shore agree to this definition. Since the 20th century, an amphibious landing of troops on a beachhead is acknowledged as the most complex of all military maneuvers. The undertaking requires an intricate coordination of numerous military specialties, including air power, naval gunfire, naval transport, logistical planning, specialized equipment, land warfare, tactics, and extensive training in the nuances of this maneuver for all personnel involved.

In the United States Navy, United States Coast Guard, United States Public Health Service Commissioned Corps (USPHS Corps), and National Oceanic and Atmospheric Administration Commissioned Officer Corps (NOAA Corps), captain is the senior-most commissioned officer rank below that of flag officer (i.e., admirals). The equivalent rank is colonel in the United States Army, Air Force, Space Force, and Marine Corps.

Reflecting its nautical heritage, the term captain is used as a military title by officers of more junior rank who command a commissioned vessel of the Navy, Coast Guard, or National Oceanic and Atmospheric Administration (NOAA) of patrol boat size or greater. Officers below O-6 who command aviation squadrons (typically O-5 commanders) usually use the less formal title "skipper".

The P400-class patrol vessels were small patrol boats of the French Navy. They were designed to accomplish police operations in the French exclusive economic zone (EEZ). They were built by the Constructions Mécaniques de Normandie, which specialise in small military craft. Two similar ships are in service in Gabon, the similar Macaé-class operates with the Brazilian Navy, and two ships were transferred from the French Navy to Kenyan and Gabon navies. The P400 class were originally designed in two versions: one armed with Exocet MM38 missiles, and another public service version with a smaller 16-man complement; eventually neither of these versions were commissioned as the French Navy chose an intermediate version.

All of these craft were based in overseas territories (DOM/TOM) where they conducted sea monitoring missions and secured the EEZ. They also executed missions in the context of French agreements with other nations, typically supporting foreign armies or carrying out humanitarian missions. Since late 2008, ships of the D'Estienne d'Orves class, with their heavy armament removed, were planned to replace the P400 in the high sea patrol role, a task for which the P400 class have proved to be underweight.

A brown-water navy or riverine navy, in the broadest sense, is a naval force capable of military operations in inland waters (rivers, lakes and inland seas) and nearshores. The term originated in the United States Navy during the American Civil War, when it referred to Union forces patrolling the muddy Mississippi River, and has since been used to describe the small gunboats and patrol boats commonly used in rivers, along with the larger "mother ships" that supported them.

Brown-water navies are typically only used for patrolling and enforcing internal waters, in contrast to blue-water navies, which can independently conduct operations in the open oceans and project power far offshore. Green-water navies, which operate mainly in brackish estuaries, bays and shallow seas not too far off coasts (typically within the bounds of exclusive economic zones), fill the operational gap between brown-water and blue-water navies.

The Guardian-class patrol boats are a class of small patrol vessels designed and built in Australia and provided to small South Pacific Ocean countries as part of the Australian Government's Pacific Maritime Security Program.

The class is designed to be updated replacements for the Pacific Forum-class patrol boats provided to its allies from 1987 to 1997. Australia provided twenty-two Pacific Forum vessels to twelve nations. They were designed to use commercial off the shelf components, to make them easier to maintain for the small nations that would operate them. Australia stood ready to help with training and maintenance, during the duration of the program, because Australia's external security issues were eased if it could count on its sovereign neighbours having resources to police their own external security.
