Alvaro de Bazan F-100 Frigate

The surface ships are the most characteristic element composing the Naval Force, and they are also the basic means with which to assure and to exert control of the sea. These ships belong to a new generation of ships developed under a multinational program. They will be equipped with a system that will guarantee the capacity of the Naval Force to operate against future aerial threats, as could be the case in the waters of the Mediterranean, where maneuvering space is limited and the earth proximity is a definitive factor.

The F-100 is an eminently flexible frigate, with special antiaerial/antimissile capability, and a potential for future growth. These frigates are medium-size escort ships, able to operate as much in coastal waters as on the high seas. It has optimized services of platform adapted to the necessities of the Group battle. Its has a great survival capability, protection against fragmentation, damage-control system and bacteriological and chemical defenses, as well as acoustic and very low magnetic radars.

It has been configured to be a frigate of moderate displacement that includes a very advanced battle system, with four main functionally segments:

  • Antiaircraft: Its main element will be the Aegis system, ordered of the exploration, detection, classification and pursuit of targets, as well as of the firing and guidance of the antiaircraft arms and the control of own interceptors.
    The nucleus of the system constitutes three-dimensional radar long-range AN/SPY-1D, with four flat antennas located in the superstructure of the ship. This configuration assures a location and much more fast pursuit targets and needs that the radars rotatable antenna, increasing the speed of reaction.
    The Aegis system will associate two radars Mk.99 illuminators for the guidance of the missiles, releasing of such function to the SPY-1D. As arms incorporate a vertical thrower Mk.41, with 48 wells for short Standard reach and short-range missiles Evolved Seasparrow average SM-2MR of and average reach, and a tube of area defense Meroka 2b associated to a radar of detection RAN30L/X.
  • Antisubmarine: The main sensors and arms will be a sonar of helmet DE-1160LF; the sonobuoys of the helicopter LAMPS III SH-60B embarked, and Mk.46 torpedoes model, launchable from the airship or 5 the Mk.32 tubes model 9 of the ship, that will be able in addition to control own airplanes of antisubmarine patrol.
  • Antisurface: It will have eight, as well as rocket launchers superficie/superficie Harpoon Mk.45 tube of 5 inches (127/54 mm), integrated with a fire control DORNA. This assembly main artilleryman has been selected by the Navy, in front of the initial option of a piece of 76 mm, to equip to the Fleet of a greater power of fire of support against coast.
  • Electronic warfare:It will incorporate the equipment Mk.9000 Elnath, for detection and interference of communications, and Aldebarán, to interfere with radar transmissions, including those of homing heads of missiles. Also it will use throwers of Mk.36 decoys model 2.

The main missions of F-100 are: crisis management, to join in allied fleets protecting expeditionary forces; its use as a standard ship in a national or allied Combat Group; and anti-submarine, antisurface and long-range antiaircraft defense, as well as the anti-missile protection of valuable own units.

The first sale of the AEGIS was to the Spanish Navy for installation aboard four F 100 frigates. The Spanish Navy selected the Aegis Combat System for its F-100 frigate program in 1996. The sale to the Spanish Navy was for installation aboard four F 100 frigates. Employing the SPY-1F phased array radar and Evolved Sea Sparrow Missile system.

The Integrated Weapons System (IWS) includes the full complement of ship sensors, weapons, computing suite and communications equipment designed to give the Nansen-class frigates advanced anti-submarine, anti-surface and anti-air capabilities. Based on the U.S. Navy's Aegis combat system, the IWS also will support interoperability of Norwegian Navy ships with those of the United States and other users of the Aegis system.

The Norwegian Navy Material Command contracted for a new line of navy frigates with a contract team compromised of Spanish shipbuilder Empresa Nacional Bazan and Lockheed Martin. Lockheed Martin provided the integrated weapon system for the new frigates, but Empresa Nacional Bazan was the integrated platform system supplier. The Spanish shipbuilder had performance responsibility over the entire platform and warranted the Lockheed Martin weapon system.

Lockheed Martin and IZAR teamed with General Dynamics' Bath Iron Works to form the Advanced Frigate Consortium (AFCON) to produce frigate-sized, Aegis-equipped surface combatants for international navies.
