When it comes to naval terminology, one term that often pops up is the “green-water navy.” But what exactly does it mean? In simple terms, a green-water navy refers to a naval force that has the capability to operate in coastal or littoral waters, typically within 200 nautical miles from shore. This type of navy falls in between a brown-water navy, which operates in shallow and inland waters, and a blue-water navy, which can venture into open oceans.
The term “green-water” comes from the color of coastal waters, which are often greener due to the presence of sediment and shallower depths compared to the deep blue waters of the open sea. Green-water navies are essential for coastal defense and protection of a country’s territorial waters, as well as for conducting various missions, including maritime sovereignty enforcement, anti-piracy operations, and disaster response.
To better understand the concept of a green-water navy, let’s take a closer look at its characteristics, missions, and examples of countries with this type of naval force.

A green-water navy possesses several distinguishing characteristics that set it apart from other types of naval forces. Here are some key features of a green-water navy:
The Capability to Operate in Coastal Waters
A green-water navy is specifically designed and equipped to operate in coastal waters, including rivers, bays, and littoral zones. They have the capability to navigate through shallower depths and maneuver in confined spaces that might not be accessible to larger blue-water navies. This allows them to conduct operations close to shore and effectively project power in their near-sea environments.
Amphibious Warfare Capabilities
Another important aspect of a green-water navy is its amphibious warfare capabilities. These navies are equipped with vessels and assets that can support amphibious operations, which involve the movement of troops, equipment, and supplies from sea to land. This capability is vital for conducting military interventions, humanitarian assistance, and disaster relief operations in coastal areas and islands.
Anti-Submarine Warfare Capabilities
Green-water navies also possess anti-submarine warfare (ASW) capabilities to protect their coastal waters from potential submarine threats. This includes the use of submarines, surface vessels equipped with sonar systems, and maritime patrol aircraft. ASW capabilities are crucial for maintaining control of coastal areas and preventing unauthorized submarine movements near a country’s territory.
Enhanced Surveillance and Intelligence Systems
To effectively operate in coastal waters and anticipate any potential threats, green-water navies invest in advanced surveillance and intelligence systems. These systems can include radars, coastal surveillance radars, maritime patrol aircraft, unmanned aerial vehicles (UAVs), and other technologies that provide situational awareness and early detection of potential risks or intrusions in their near-sea environments.
By combining these capabilities, a green-water navy can fulfill its missions effectively and protect the coastal areas and territorial waters of its nation.
Several countries around the world maintain green-water navies to safeguard their coastal waters and project power in their near-sea environments. Here are a few examples:
India
India’s navy is considered a green-water navy due to its significant presence and capabilities in the Indian Ocean region. With a fleet comprising of aircraft carriers, destroyers, frigates, submarines, and amphibious assault ships, the Indian Navy has the ability to safeguard its vast coastline, protect its strategic interests, and conduct operations in the regional waters bordering the Indian subcontinent.
Brazil
Brazil possesses a green-water navy that is responsible for protecting its extensive coastline along the Atlantic Ocean. The Brazilian Navy operates a variety of surface vessels, submarines, and aircraft to maintain control of its territorial waters and enforce its maritime sovereignty. Brazil’s naval assets also support missions such as surveillance, search and rescue operations, and maritime law enforcement.
Australia
Australia’s navy is often classified as a hybrid navy, as it operates both as a green-water navy and a blue-water navy. The Royal Australian Navy maintains a strong presence in the Indo-Pacific region, protecting its vast coastline and conducting operations in the waters of Southeast Asia and the Pacific. With a fleet of surface combatants, submarines, and amphibious vessels, Australia’s navy plays a vital role in regional security and maritime stability.
These are just a few examples of countries with green-water navies, highlighting the importance of maintaining a versatile naval force capable of operating in coastal waters.
In Conclusion
A green-water navy is a critical component of a nation’s maritime defense strategy. With the ability to operate in coastal waters, conduct amphibious operations, and maintain control over its territorial waters, a green-water navy serves as the first line of defense and supports various missions ranging from maritime law enforcement to disaster response.
Understanding the concept and characteristics of a green-water navy helps us comprehend the complexity and diversity of naval forces across the world. It showcases the importance of adapting naval capabilities to specific operational environments and highlights the unique challenges faced by navies operating in littoral regions.
Whether it’s India protecting its interests in the Indian Ocean, Brazil safeguarding its coastline along the Atlantic, or Australia maintaining regional stability in the Pacific, green-water navies play a crucial role in ensuring the security and prosperity of nations in their near-sea environments.
