The frigates are vessels designed to achieve the strategic objectives of the National Defence of any nation in the 21st century. There are its antisurface, antisubmarine and especially antiaircraft capabilities which make this vessel the essential platform to guarantee the defense and control of all areas under the sovereignty of a country.

Additionally, they are an indispensable tool in a Nation’s Foreign Policy, acting both in conflict operations and in peace and humanitarian missions, as well as in the performance of UN resolutions.

Its high capacities and the flexibility to operate both in coastal areas and on the high seas allow it to act as command and control vessel in operations with allied fleets, providing the required coverage.

Navantia is a world reference in the design and construction of frigates, having built the F-100 for the Spanish Navy, as well as different ships for the Norwegian Navy or the Australian Navy. Navantia is currently developing the F-110 frigate program for the Spanish Navy.

All countries wish to control their jurisdictional waters in order to defend their territory against daily-changing threats, such as international terrorism, illegal weapons proliferation, drug dealing and human trafficking. Maritime traffic control, whether by inspecting ships or defending them against piracy, is a key activity for the economic activity of any country.

In addition, many navies of the world also have under their responsibility the carry out of campaigns of oceanic research, protection of the underwater historical heritage and defense of the fishery resources.

So, these ships must face very different missions, both in waters close to the national territory, and in international missions; such as the Atalanta operation in the Horn of Africa or the Sofia operation in Mediterranean waters.

Due to this variety of missions to be carried out by patrol vessels, its design should guarantee long periods at sea with optimal operating conditions and reduced operation and life cycle cost; these vessels must be prepared to operate in marine pollution fight or human search and rescue missions.

Navantia has built 4 MAV units for the Spanish Navy (with two more under construction), 4 SOP (Surveillance Oceanic Patrol vessel) units and 3 CSV (Coastline Surveillance Vessel) units for the Venezuelan Navy.

Some of the main limitations of any military vessel is to stay longer on the high seas or reach more distant destinations, the solution is the need to stock up on everything necessary (fuel, food, people, ammunition, etc.) in order to continue its mission.

This type of vessel covers this need, as it can supply up to three ships at the same time; fuel, water, food, ammunition and other materials on the high seas. In addition, its hospital on board, its capacity to transport containers and the large volume of its tanks, among other benefits, allows this ship to carry out missions of humanitarian and health assistance to civilians in circumstances of catastrophe and environmental defense.

Navantia has built the CSS Cantabria vessel for the Spanish Navy and and two very similar units for Australia: Stalwart and Supply. This design integrates military and civil concepts and complies with current international environmental regulations regarding the provision of double hull.

State-of-the-art conventional ocean-going submarine designed and built entirely in Spain. One of its outstanding features is its third-generation air-independent propulsion system (AIP) known as BEST (Bio-Ethanol Stealth Technology), which consists of a bioethanol reformer to produce hydrogen, which in turn reacts with oxygen in a fuel cell generating electricity. This system enables the vessel to extend its endurance, operating independently under water for up to three weeks, which considerably reduces its level of detectability.

It is a highly automated submarine that thanks to the state-of-the-art platform control system developed by Navantia Sistemas, allows it to be operated by a limited number of crew members (32 sailors and 8 berths for additionally embarked personnel), which can reach an underwater speed of more than 19 knots, and a maximum depth capacity of over 300 m. It is approximately 80 m long, 7 m in diameter, has a submerged displacement of 3,000 tonnes.

It also features a combat system developed by Navantia Sistemas in collaboration with the US firm Lockheed Martin, with capacity, unique (for NATO and EU) amongst conventional submarines of similar characteristics, to launch land attack tactical missiles.
