A green-water navy is a maritime force that is capable of operating in its state's littoral zones and has limited competency to operate in the surrounding marginal seas. [1] It is a relatively new term, and has been created to better distinguish, and add nuance, between two long-standing descriptors: blue-water navy (deep waters of open oceans) and brown-water navy (littoral waters and near to shore).

Contents

As a non-doctrinal term with no concrete legal or political definition, it can be used in several different ways. It originated with the United States Navy, who use it to refer to the portion of their fleet that specializes in offensive operations in coastal waters. Nowadays such ships rely on stealth or speed to avoid destruction by shore batteries or land-based aircraft.

The US Navy has also used the term to refer to the first phase of the expansion of the Chinese Navy into a full blue-water navy. Subsequently, other authors have applied it to other national navies that can project power locally but cannot sustain operations at range without the help of other countries. 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.

Definitions

The elements of maritime geography are loosely defined and their meanings have changed throughout history. The US's 2010 Naval Operations Concept defines blue water as "the open ocean", green water as "coastal waters, ports and harbors", and brown water as "navigable rivers and their estuaries". [2] Robert Rubel of the US Naval War College includes bays in his definition of brown water, [3] and in the past US military commentators have extended brown water out to 100 nautical miles (190 km) from shore. [4]

During the Cold War, green water denoted those areas of ocean in which naval forces might encounter land-based aircraft. [3] The development of long-range bombers with anti-ship missiles turned most of the oceans to "green" and the term all but disappeared. [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. This prompted the development of ships designed to operate in such waters – the Zumwalt-class destroyer and the littoral combat ships; modeling has suggested that current NATO frigates are vulnerable to swarms of 4-8 small boats in green water. [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. [3]

As the preeminent blue-water navy of the early 21st century, the US Navy is able to define maritime geography in terms of offensive action in the home waters of its enemies, without being constrained by logistics. 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. A number of countries are working on overcoming these constraints. Other authors have started to apply the term "green-water navy" to any national navy that has ocean-going ships but lacks the logistical support needed for a blue-water navy. It is often not clear what they mean, as the term is used without consistency or precision.

A green-water navy does not mean that the individual ships of the fleet are unable to function away from the coast or in open ocean: instead, it suggests that due to logistical reasons they are unable to be deployed for lengthy periods and must have aid from other countries to sustain long term deployments. Also, the term "green-water navy" is subjective as numerous countries that do not have a true green-water navy maintain naval forces that are on par with countries that are recognized as having green-water navies. For example, the German Navy has near the same capability as the Canadian Navy but is not recognized as a true green-water navy. Another example is the Portuguese Navy that, despite being usually classified as a minor navy, has several times conducted sustained operations in faraway regions typical of the green-water navies. However, the differences between blue-water navies and brown or green-water navies are usually quite noticeable, for example, the US Navy was able to quickly respond to the disappearance of Malaysia Airlines Flight 370 and continue operations in the region with relative ease even though the search area covered the Indian Ocean. In contrast, in 2005 the then green-water Russian Navy was unable to properly respond when its AS-28 rescue vehicle became tangled in undersea cables unable to surface, relying on the blue-water Royal Navy to respond and carry out the rescue in time. [7]

Just as states build up naval capability, some lose it. For example, the Austro-Hungarian Navy was a modern green water navy of the time, but as the countries lost their coasts during World War I, their navies were confiscated, and their ports became parts of Italy and Yugoslavia. The Axis powers lost naval capabilities after their defeat in World War II, with most of Japan's Imperial Navy and Germany's Navy being disarmed and their troop and ship numbers capped and monitored by the Allies. The collapse of the USSR also brought with it the collapse of the second-largest naval force in the world, and the largest submarine force in the world. Although the Russian Federation made sure to inherit the most capable ships, passing most older models to successor states, as it had lost the logistical capabilities of the Soviet Navy, it was no longer able to operate away from Russian shores for extended periods of time. Moreover, budget cuts forced large cuts in the submarine force, such as the retirements of the Typhoon-class submarine. As the Soviet Navy was built largely around submarine warfare the losses in the submarine capability have adversely affected the capability of the newly formed Russian Navy as well.

The Royal Australian Navy is well established as a green-water navy. [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. Since the early 2000s, the Brazilian Navy has contributed to a number of peacekeeping and humanitarian missions:

According to the criteria as outlined in the 2001 publication, "Leadmark: The Navy's Strategy for 2020", the Royal Canadian Navy had met its description of a 3rd tier "Medium Global Force Projection Navy" – a green-water navy with the capacity to project force worldwide with the aid of more powerful maritime allies (e.g. United Kingdom, France and the United States). [9] In this context, the Royal Canadian Navy ranked itself alongside the navies of Australia and the Netherlands: [9]

Japan

The Japan Maritime Self-Defense Force is considered to be a green-water navy. [8] Overseas JMSDF deployments include participation in the Combined Task Force 150, [13] [14] and an additional task force in the Indian Ocean from 2009 to combat piracy in Somalia. The first postwar overseas naval air facility of Japan was established next to Djibouti-Ambouli International Airport: [15]

The Royal Netherlands Navy has been officially described as a 3rd tier "Medium Global Force Projection Navy" – or a green-water navy with the capacity to project force worldwide with the aid of more powerful maritime allies (e.g. Britain, France and the United States). [9] In this context, the Royal Netherlands Navy ranks alongside the navies of Australia and Canada, while the USN is a 1st tier global blue-water navy and Britain and France are 2nd tier blue-water navies. [9] For many years since the end of the Cold War, the Royal Netherlands Navy has been changing its role from national defence to overseas intervention: [16]

Spain

The Spanish Navy is a green-water navy, and participates in joint operations with NATO and European allies around the world. [17] The fleet has 54 commissioned ships, including; one amphibious assault ship (also used as an aircraft carrier), two amphibious transport docks, 5 AEGIS destroyers (5 more under construction), 6 frigates, 7 corvettes (2 more under construction) and three conventional submarines. (4 under construction)

South Korea

The Republic of Korea Navy is considered to be a green-water navy. [8] In 2011, the government authorized the building of a naval base on Jeju Island to support the new Dokdo-class amphibious assault ships, the base will also be capable of supporting joint forces with the US Navy. [18] A ski-jump for the operation of V/STOL jet fighters is being considered for the second ship of the Dokdo class. [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. [20] On December 3, 2021, the National Assembly passed the budget to fund a fixed-wing aircraft carrier tentatively named CVX-class aircraft carrier capable of operating F35B, expected to enter operations possibly as early as 2033 Link Link Link South Korea participates in the Combined Task Force 151 with the expeditionary force Cheonghae Unit:

According to a report by Haifa University, Turkey's naval might has become a significant source of concern for the Middle East and the Balkans, as they have greatly modernized its maritime force in recent years. [21] The study puts the Turkish Naval Forces as the strongest in the region (Middle East), and describes the Turkish navy as being a "green-water navy". 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. Guetta also highlighted the Turkish Navy's strike force and intervention capacity. A flagship project is the construction of TCG Anadolu, an amphibious assault ship that can serve as a light aircraft carrier. 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. The Turkish Navy, as of 2021, has a total of 156 naval assets, but Turkey plans to add a total of 24 new ships, which include four frigates, before the Republic reaches the 100th anniversary of its founding in 2023:

Iran

Recently Iran has tried to expand its naval presence out of its own territorial waters by building new indigenous warships like Mowj-class frigates. Iran also participates in joint naval exercises with countries like Russia, China and India. The Iranian navy mostly operates in the Persian Gulf, Gulf of Oman, Indian Ocean, Red Sea, Caspian Sea, and the Mediterranean and has a fleet of 9 frigates (2 under construction), 17 corvettes and 35 conventional submarines (2 under construction). [23]

Additionally, Iran has a second navy branch, The IRGC-N. Naval branch of IRGC mostly operates land-based cruise missiles and speedboats each carrying a variety of weapons, from anti-ship missiles to torpedoes and even rockets. This is suitable for the mission this force has, protecting local waters in Persian Gulf, Gulf of Oman, and the Caspian Sea. Though this force expanded its arsenal by building missile corvettes and forward base ships, Like 4 Shahid Soleimani-class double hulled ships (1 under construction)to operate much further than Iranian local waters:

<span class="mw-page-title-main">Aircraft carrier</span> Warship that serves as a seagoing airbase

An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role of flagship of a fleet. One of its great advantages is that, by sailing in international waters, it does not interfere with any territorial sovereignty and thus obviates the need for overflight authorizations from third-party countries, reduces the times and transit distances of aircraft and therefore significantly increases the time of availability on the combat zone.

Surface combatants are a subset of naval warships which are designed for warfare on the surface of the water, with their own weapons and armed forces. They are generally ships built to fight other ships, submarines, aircraft or land targets, and can carry out several other missions including counter-narcotics operations and maritime interdiction. Their primary purpose is to engage space, air, surface, and submerged targets with weapons deployed from the ship itself, rather than by manned carried craft.

The Fleet Air Arm (FAA), known formerly as the Australian Navy Aviation Group, is the division of the Royal Australian Navy (RAN) responsible for the operation of aircraft. The FAA was founded in 1947 following the purchase of two aircraft carriers from the Royal Navy. FAA personnel fought in the Korean War and the Vietnam War, and participated in later conflicts and operations from host warships.

The Royal Australian Navy, although a significant force in the Asia-Pacific region, is nonetheless classed as a medium-sized navy. Its fleet is based around two main types of surface combatant, with limited global deployment and air power capability. However, in 2009, a white paper, Defending Australia in the Asia Pacific Century: Force 2030, was produced by the Australian government which set out a programme of defence spending that will see significant improvements to the RAN's fleet and capabilities. In recent times, Australia released its Surface Fleet Review in 2024, which analyses the future of the RAN and shows what the Government will procure.
