Green-water navy

Such navies typically have amphibious ships and sometimes small aircraft carriers, which can be escorted by destroyers and frigates with some logistical support from tankers and other auxiliaries.

[3] After the Cold War, US amphibious task forces were sometimes referred to as the green-water navy, in contrast to the blue-water carrier battle groups.

[5] This distinction disappeared as increasing threats in coastal waters forced the amphibious ships further offshore, delivering assaults by helicopter and tiltrotor from over the horizon.

[6] Rubel has proposed redefining green water as those areas of ocean which are too dangerous for high-value units, requiring offensive power to be dispersed into smaller vessels such as submarines that can use stealth and other characteristics to survive.

[3] Under his scheme, brown water would be zones in which ocean-going units could not operate at all, including rivers, minefields, straits, and other choke points.

This is not true for most other navies, whose supply chains and air cover typically limit them to power projection within a few hundred kilometers of home territory.

[8][9] The navy sustains a broad range of maritime operations, from the Middle East to the Pacific Ocean, often as part of international or allied coalitions.

[10] The RAN operates a modern fleet, consisting of destroyers, frigates, conventional submarines as well as an emerging amphibious and power projection capability based on the commissioning of HMAS Choules and two Canberra-class landing helicopter docks:[11] The Brazilian Navy has frequently been dubbed a "green-water" force by experts.

[12] The navy is primarily focused on securing the country's littorals and exclusive economic zone (EEZ), but also maintains the capacity to operate in the wider South Atlantic Ocean.

[19] The Korean government is considering to buy surplus Harriers as a possible interim for the F-35 Lightning II if they choose to operate VTOL aircraft at all.

According to Israeli Colonel Shlomo Guetta, one of the report's authors, Turkey is building a Navy that characterises a regional power and can conduct long-range operations.

Quoting US military expert Richard Parley's estimates,[22] the report argued that the new warship will offer Turkey unprecedented strike capabilities in the Black Sea and Eastern Mediterranean.
