Indian Navy Ranks Explained: Commissioned, Junior & Non-Commissioned Officers

Indian Navy Rank Structure Simplified

Before the deep dive, here’s how the Indian Navy officers are structured into three core groups:

Commissioned Officers: The senior leadership of the Navy, responsible for strategic planning, commanding ships and submarines, and making critical operational decisions both at sea and on shore.

Junior Commissioned Officers (JCOs): Serving as a bridge between commissioned officers and enlisted personnel, JCOs supervise teams, manage technical operations, and provide guidance on daily naval tasks.

Non-Commissioned Officers (NCOs): The backbone of the Navy, NCOs and enlisted sailors carry out essential operational and technical duties. They are responsible for the maintenance of equipment, execution of tasks, and supporting both JCOs and commissioned officers.

Commissioned Officers in the Indian Navy

Commissioned Officers form the leadership core of the Indian Navy, responsible for planning missions, commanding ships and submarines, and making decisions at sea and ashore. Their journey begins as Midshipmen and Sub Lieutenants, with ranks progressing through a structured hierarchy.

Entry into this cadre is possible through multiple routes, including education and training at institutes such as the NDA (National Defence Academy) and INA (Indian Naval Academy). Each route has its own selection process and training path. No matter the route, the goal remains the same—preparing officers for the demanding standards of naval leadership.

Here’s how the ranks progress in the Indian Navy in ascending order:

Midshipman: After completing the initial phase of training at institutions like the Indian Naval Academy (INA), cadets are granted the rank of Midshipman. At this stage, they are probably in their last year of training to become a commissioned officer, gaining practical exposure at sea and familiarising themselves with naval life.

Sub Lieutenant: On successfully completing training, a Midshipman is commissioned as a Sub Lieutenant, the first official officer rank in the Indian Navy. Sub Lieutenants take up junior leadership roles, supporting senior officers in navigation, operations, and administration.

Lieutenant: After proving themselves as Sub Lieutenants and completing the required professional courses, officers rise to the rank of Lieutenant. It takes approximately two years to become a Lieutenant from the time an individual is commissioned as a Sub-Lieutenant. Lieutenants are entrusted with crucial operational and staff appointments, both at sea and on shore. They ensure that day-to-day activities run smoothly.

Lieutenant Commander: The next transition is to the rank of Lieutenant Commander, which marks the shift from a junior officer to a mid-level officer. Promotion to this rank generally comes after 8–10 years of commissioned service. Their responsibilities include commanding smaller ships, leading departments, overseeing operations on larger vessels, and training junior officers.

Commander: Officers at this rank take on senior command and staff roles. A Commander may be the commanding officer of a warship, submarine, naval air squadron, or a major shore establishment. They are also entrusted with operational planning, unit-level leadership, and tactical decision-making, acting as a crucial link between mid-level and top leadership.

Captain: Upon reaching the rank of Captain, an officer is equivalent to a Colonel in the Indian Army and a Group Captain in the Indian Air Force. They serve as the commanding officer of large warships such as destroyers, frigates, or aircraft-carrying vessels. Beyond sea command, Captains also hold senior administrative, operational, and strategic responsibilities within naval establishments. At sea, they lead teams of officers and Agniveers, ensuring mission readiness, discipline, and effectiveness.

Commodore: At this stage, the officer attains a one-star rank and a senior commissioned officer position. Commodores typically command naval bases, flotillas, or squadrons, overseeing the operations of multiple ships or units. The rank marks a key step in an officer’s career, where responsibilities extend beyond a single vessel to broader operational and administrative leadership. It also involves strategic planning and coordination in naval operations.

Rear Admiral: A Rear Admiral is a two-star Flag Officer rank and one of the senior-most leadership positions in the Navy. Officers at this level command major naval formations such as fleets and naval areas or serve in key staff appointments at Naval Headquarters. They may lead a fleet comprising multiple warships, coordinating missions and ensuring operational effectiveness. They are responsible for combat readiness, logistics, and personnel management within their command.

Vice Admiral: A Vice Admiral is a three-star Flag Officer rank, among the highest leadership positions in the Indian Navy. Officers at this level command operational forces or hold high-level administrative appointments at Naval Headquarters, acting as a deputy to the most senior officer, like the Chief of the Naval Staff. They are responsible for large-scale planning, force readiness, and the maintenance and lifecycle of critical systems, often serving as the Flag Officer Commander-in-Chief of major commands like the Western or Eastern Naval Commands.

Admiral: After decades of distinguished service, the Admiral is the senior-most rank a commissioned officer can attain in the Indian Navy. The officer holding this four-star rank serves as the Chief of the Naval Staff (CNS), the professional head of the Navy. As the top naval leader, the Admiral represents the Navy at national and international levels, shapes maritime policy, guides the future direction of naval power, and ensures the security of India’s maritime interests and borders in both peace and conflict.

Junior Commissioned Officers (JCOs) & Non-Commissioned Officers (NCOs) in the Indian Navy

Junior Commissioned Officers (JCOs) form an important link between NCOs and Commissioned Officers. These are seasoned sailors elevated to greater leadership and responsibility. They play a vital role in day-to-day operations, guiding sailors under their charge and serving as the bridge between the crew and the officers.

Non-Commissioned Officers (NCOs) are skilled sailors who take on supervisory and specialist responsibilities. They do not receive any commissioned rank but rise through the sailor ranks, gaining authority through experience, technical expertise, and steady promotions within the cadre.

Let’s go through these JCOs and NCOs ranks in ascending order:

Chief Petty Officer: This is the entry rank into the Junior Commissioned Officer (JCO) cadre in the Indian Navy. At this stage, sailors transition from primarily technical duties to roles that combine both expertise and leadership. A Chief Petty Officer supervises daily operations within their department, guides junior sailors, and ensures that tasks are carried out efficiently.

Master Chief Petty Officer 2nd Class: At this senior JCO rank, sailors take charge of key technical departments and lead teams of specialists, ensuring that critical systems and equipment remain in proper working order. Along with their technical expertise, they provide leadership and mentorship to junior sailors, making them central to the smooth functioning of ship and shore establishments.

Master Chief Petty Officer Ist Class: This is the highest Junior Commissioned Officer (JCO) rank in the Indian Navy. Sailors at this level are both technical experts and respected leaders within their field. They often serve as the senior-most enlisted advisors, working closely with the commanding officer to ensure smooth communication between the ship’s command and its sailors.

Seaman Ist Class & 2nd Class: These are the entry-level enlisted sailor ranks in the Indian Navy. Seamen carry out basic operational, technical, and maintenance duties under supervision.

Leading Rate (NCO): The Leading Rate is a sailor rank where individuals guide junior sailors in daily tasks and technical duties. They ensure discipline, assist in training, and act as the immediate link between the sailors and Petty Officers.

Petty Officer: A senior Non-Commissioned Officer (NCO) rank, the Petty Officer leads small teams and oversees specific technical or operational duties on board. They support junior sailors with training, ensure discipline, and maintain smooth functioning within their section. This rank marks the transition from individual tasks to small leadership responsibilities.

Why Navy Ranks Are Essential

In the Navy, a clear rank structure isn’t just about titles—it’s the backbone of discipline, efficiency, and leadership. Each rank defines specific roles and responsibilities, ensuring that orders are executed quickly and correctly, especially during critical missions at sea.

Ranks also help develop leaders at every level, from junior officers learning the ropes to senior officers commanding ships and fleets. This hierarchy keeps the Navy organised, maintains discipline, and allows teams to function seamlessly.

From Sailor to Admiral: Indian Navy — A Unified Force

Every ship that sails and every mission the Indian Navy undertakes is the result of a finely tuned team, where Commissioned Officers, Junior Commissioned Officers, and Non-Commissioned Officers each play their part.

From the Admiral leading commands, to the JCOs guiding the crew, to the sailor carrying out critical tasks, every role is a thread in a larger story of duty and vigilance. Together, they form a living, breathing force—where discipline meets dedication, and every hand on deck matters in keeping India’s waters safe.
