The Mexican Navy is one of the two independent armed forces of Mexico. The actual naval forces are called the Armada de México. The Secretaría de Marina (SEMAR) (English: Naval Secretariat) includes both the Armada itself and the attached ministerial and civil service. The commander of the Navy is the Secretary of the Navy, who is both a cabinet minister and a career naval officer.

The Mexican Navy's stated mission is "to use the naval force of the federation for external defense, and to help with internal order".^[2] As of 2020, the Navy consists of about 68,200 men and women plus reserves,^[3] over 189 ships, and about 130 aircraft.^[4][5] The Navy attempts to maintain a constant modernization program to upgrade its response capability.

Given Mexico's large area of water (3,149,920 km² (1,216,190 sq mi)) and extensive coastline (11,122 km (6,911 mi)), the Navy's duties are of great importance. Perhaps its most important on-going missions are the war on drugs and protecting PEMEX's oil wells in Campeche in the Gulf of Mexico. Another important task of the Mexican Navy is to help people in hurricane relief operations and other natural disasters.

The Mexican navy is the second largest navy in Latin America and North America, and the third largest in the Americas after the United States and Brazil.

The Mexican Navy has its origins in the creation of the Ministry of War in 1821. From that year until 1939 it existed jointly with the Mexican Army in the organic ministry. Since its declaration of independence from Spain in September 1810, through the mid decades of the 19th century, Mexico found itself in a constant state of war, mostly against Spain which had not recognized its independence. Therefore, its priority was to purchase its first fleet from the U.S. to displace the last remaining Spanish forces from its coasts.^[6]

The Mexican Navy has participated in many naval battles to protect and defend Mexico's interests. Some of the most important battles were:

The President of Mexico is commander in chief of all military forces. Day-to-day control of the Navy lies with the Navy Secretary, José Rafael Ojeda Durán.^[7] In Mexico there is no joint force command structure with the army, so the Secretary reports directly to the President. The Navy has a General Headquarters and three naval forces. There are furthermore eight regions (four on the Pacific coast, three on the Mexican Gulf coast and the Región Naval Central, grouping the naval forces, based in and around the capital Mexico City, such as the 7th Naval Infantry Brigade, the Central Special Operations Group and the Air Transport Squadron), thirteen zones, and fourteen naval sectors.

The Navy is divided into three main services designated as "forces":

• Gulf and Caribbean Sea Naval Force
• Pacific Naval Force
• Naval Infantry Force

Other notable services include:

• Naval Aviation
• Search and Rescue

Officers are trained at the Mexican Naval Academy, called the "Heroica Escuela Naval Militar" ("Heroic Military Naval School"), located in Antón Lizardo, Veracruz.

The Navy offers several options for graduate studies in their educational institutions:

Heroica Escuela Naval Militar

It is the school where future officers are trained for the General Corps of the Navy. Candidates can enter upon completing high school. Upon completion of studies, graduates obtain the degree of Sub-Lieutenant and the title of Naval Science Engineer.

Naval Medical School

This school Located in Mexico City, offers a career in medicine. Officers are trained with skills for the prevention and health care of naval personnel. By adopting a professional examination, graduates are commissioned Sub-Lieutenants.

In the Naval Engineering School, officers are responsible for the preventive and corrective maintenance of systems and electronic equipment installed on ships and installations of the Mexican Navy. This school offers career of Electronic Engineering and Naval Communications. It is located between the town of Mata Grape and Anton Lizardo, 32 km (20 mi) from the port of Veracruz.

The annual Navy's budget is in a one to three proportion of the national budget relative to the Mexican Army and Mexican Air Force. The Navy has a reputation for being well-run and well-organized. This reputation allows for a close relationship with the United States Navy (USN), as evidenced by the procurement of numerous former USN ships.

The Mexican Navy includes 60 smaller patrol boats and 32 auxiliary ships. It acquired 40 fast military assault crafts, designated CB 90 HMN, between 1999 and 2001 and obtained a production license in 2002, enabling further units to be manufactured in Mexico.

This section needs to be updated. (June 2018)

For the year 2008 budget, the Mexican Congress approved a US$15 million fund to build only 17 out of the 60 combat boats requested. These ships, designated CB 90 HMN, are to increase the Mexican Navy's fast boat fleet. Additional budgets will be awarded each passing year.^[42] In total, the Mexican Navy has over 189 operational ships.^[4]

In January 2013, the 112th Session of US Congress authorized the transfer of the Oliver Hazard Perry-class frigates USS Curts and USS McClusky to the Mexican Navy,^[43] but due to the cost of overhauling the vessels and the removal of all the weapons systems and most of the electronics and radar gear by the USN prior to transfer, this is still undecided by Mexico. The offer expired on January 1, 2016.^[43]
