It has the largest navy of any landlocked country in the world

Despite the fact that it lacks a coastline, Paraguay has the greatest navy of any landlocked country in the world. It also has naval aviation, a coastguard, and a river defense force. The Paraguayan navy operates on its rivers and has access to the ocean via Argentina.

Despite being a landlocked country, Paraguay has a rich nautical legacy due to its access to the Atlantic Ocean via the Paraguay–Paraná rivers. The Paraguayan Navy operates from twelve bases. Asuncion's primary base is Puerto Sajonia, followed by Bahia Negra, Ciudad del Este, Encarnacion, and Salto del Guaira. In Puerto Sajonia, also offers aviation facilities.

In terms of ships, the Navy has 34 surface ships, some of which are over 100 years old. The Paraguay Navy's major vessel and the flagship are still the Humaita, which was commissioned before Paraguay's engagement in the Chaco War. It also possesses four patrol vessels, the oldest of which was commissioned in 1908 and the newest in 1985. The Navy now has 17 patrol boats of varied drafts, four of which were provided by Taiwan and the United States, and the remaining 13 were manufactured domestically. The remaining vessels in the fleet include tugboats, barges, landing craft, transporters, and a presidential yacht. The new additions include four Croc-class riverine vessels from Australia, as well as 43 locally made riverine patrol vessels produced between 2006 and 2009.
