F100 Alvaro de Bazan Class Frigate

The F100 Alvaro de Bazan Class is a 5,800t multipurpose frigate built by the Spanish shipbuilder, Izar (formerly E.N. Bazan). In February 2005, the naval shipbuilding activities of Izar were spun off into a new company, Navantia.

The first batch of four ships was ordered by the Spanish Navy in January 1997. The first, Alvaro de Bazan (F101), was launched in October 2000 and commissioned in September 2002. The second, Almirante Juan de Borbon (F102), was launched in February 2002 and commissioned in December 2003.

The third, Blas de Lezo (F103) was launched in May 2003 and commissioned in December 2004. The fourth, Mendez Nunez (F104), was launched in November 2004 and delivered in March 2006.

In June 2005, the Spanish Government announced plans to procure a fifth Alvaro de Bazan Class vessel, Cristobal Colon (F105). Procurement of the new vessel was authorised by the government in May 2006. Construction began in June 2007 and the keel was laid in February 2009. The ship was launched in November 2010 and entered sea trials in June 2012. A sixth vessel, Juan de Austria (F106) is also planned, to commission in 2013.

The F-100 frigate is a multi-purpose ship with the following capabilities:

  • Medium-size oceanic escort.
  • Command and control ship in conflict scenarios, capable of operating with allied fleets, and providing cover to expeditionary forces.
  • Capable of operating in coastal and blue waters depending on the conflict situation.
  • High anti-air capability.

The F-100 project entails important challenges; among them:

  • An AEGIS Combat System around the SPY-1D radar which, up to now, was used only in larger combatants such as destroyers and cruisers.
  • Integrate national weapons and sensors into the AEGIS System.
  • Other specific developments like the Navigational Data distribution (DIANA) or the Platform Control Integrated System.

Alvaro de Bazan Class Aegis combat system

Álvaro de Bazán – david –

The ship incorporates the AN/SPY-1D Aegis Combat System from Lockheed Martin Naval Electronics and Surveillance Systems. The main missions of the ship are fleet protection, anti-air warfare, operation as a flag ship for a combat group, anti-surface and anti-submarine warfare.

In June 2008, Spain requested the foreign military sale (FMS) of Raytheon Tomahawk Block IV land attack missiles to arm the F100 frigates.

Alvaro de Bazan is the first European ship with the Aegis weapon system. In July 2003, Alvaro de Bazan (F101) took part in combined Combat Systems Ship Qualification Trials (CSSQT) with the Aegis Class destroyer USS Mason (DDG 87). A second CSSQT trial took place in September 2004 with Almirante Juan de Borbon (F102) and USS Pinkney (DDG 91). In June 2007, Mendez Nunez (F104) took part in the first tri-nation CSSQT, with Arleigh Burke class destroyer USS Gridley (DDG 101) and the Royal Norwegian Navy frigate Fridtjof Nansen (F310).

Nansen Class Anti-Submarine Warfare Frigate: Details

In 1994 Spain entered an agreement with Germany and the Netherlands, which provided cooperation in development and in national construction of the frigates. In Spain, Izar built the F100, in the Netherlands, Royal Schelde built the LCF (De Zeven Provincien Class) and in Germany the ARGE 124 group (Blohm and Voss as the leading yard, Howaldtwerke-Deutsche Werft and Thyssen Nordseewerke) built the F124 (Sachsen Class). The agreement covered cooperation on the ship platform and not on the systems.

RGM-84 Harpoon anti-ship missile

The Harpoon is an all weather, subsonic, over the horizon, anti-ship missile which can be launch from surface ships, submarines and aircraft. Its guidance system consists of a 3-axis integrated digital computer/ radar altimeter for midcourse guidance, and an active radar seeker for the terminal phase of the flight.

The Harpoon flies at subsonic speeds, with a sea-skimming flight trajectory for improved survivability through reduced probability of detection by enemy defenses. It was designed to strike enemy ships in an open ocean environment.

The ship launched RGM-84 Harpoon was introduced in 1977, as well as the encapsulated submarine launched UGM-84.

RIM-162 Evolved Sea Sparrow

RIM-162 ESSM was developed by the U.S. Navy in cooperation with an international consortium of other NATO partners plus Australia. ESSM is a short-range, semi-active homing missile that makes flight corrections via radar and midcourse data uplinks. The missile provides reliable ship self-defense capability against agile, high-speed, low-altitude anti-ship cruise missiles (ASCMs), low velocity air threats (LVATs), such as helicopters, and high-speed, maneuverable surface threats. ESSM is integrated with a variety of U.S. and international launchers and combat systems across more than 10 different navies.

ESSM has an 8-inch diameter forebody that tapers to a 10-inch diameter rocket motor. The forebody includes a guidance section uses a radome-protected antenna for semi-active homing and attaches to an improved warhead section. A high-thrust, solid-propellant 10-inch diameter rocket motor provides high thrust for maneuverability with tail control via a Thrust Vector Controller (TVC).

ESSM’s effective tracking performance and agile kinematics result from S- and X-band midcourse uplinks, high average velocity and tail control, increased firepower through a vertical “quad pack” launcher (Mk-41 VLS), and greater lethality with a warhead designed for defeating hardened ASCMs.

Tomahawk cruise missile


Tomahawk is an all-weather submarine or ship-launched land-attack cruise missile. After launch, a solid propellant propels the missile until a small turbofan engine takes over for the cruise portion of flight. Tomahawk is a highly survivable weapon. Radar detection is difficult because of the missile’s small cross-section, low altitude flight. Similarly, infrared detection is difficult because the turbofan engine emits little heat. Systems include Global Positioning System (GPS) receiver; an upgrade of the optical Digital Scene Matching Area Correlation (DSMAC) system; Time of Arrival (TOA) control, and improved 402 turbo engines.

The Tomahawk land-attack cruise missile has been used to attack a variety of fixed targets, including air defense and communications sites, often in high-threat environments. The land attack version of Tomahawk has inertial and terrain contour matching (TERCOM) radar guidance. The TERCOM radar uses a stored map reference to compare with the actual terrain to determine the missile’s position. If necessary, a course correction is then made to place the missile on course to the target. Terminal guidance in the target area is provided by the optical Digital Scene Matching Area Correlation (DSMAC) system, which compares a stored image of target with the actual target image. Source

DORNA is an evolved concept of a Fire Control System oriented towards client needs which accordingly adapts its interfaces to the vessel’s Combat System, Navigation System, Weapons, or on-board video distribution system.

It boasts anti-air warfare, surface, and coastal capabilities, besides surveillance, training and maintenance features, as well as other secondary features such as navigation support, warning rounds, etc.

It is available in two basic configurations: either equipped with a monitoring radar and
electrical-optical sensors (such as the ones installed in frigates F100 and BAM ships of the
Spanish Navy) or only with electric-optical sensors (such as those installed in LCS ships of the
US Navy). Source

As in Eletro-optical variante, the new generation is DORNA R/E-O Mod3A FCS which includes enhanced functionalities such as Post-mission analysis and Improved Onboard Training, apart from great compaction and simplified Through Life Support.

In both variants, DORNA comprises the following units:

  • Console. Its main task is to act as the human machine interface (HMI) center for the operator’s actions and supervision. It is optional, as DORNA can be integrated and handled from a Multi-Function Console of the CMS, if any.
  • FCS Director. It is a stabilized tracker mount with sensors, besides the associated control unit and (depending on the application) the tracking radar units.

The first four F-100 ships are equipped with the Lockheed Martin AN/SPY-1D fixed phased array radar for air and surface search. AN/SPY-1D is a multi-function E/F band, three-dimensional radar which is an essential part of the Aegis system. It provides instantaneous beam steering, target detection, fire control tracks on hundreds of targets, and multiple target kill assessment.

“The main missions of the F100 frigate include fleet protection and anti-air warfare.”

Army/Navy Joint Electronics Type Designation System/AN/SPY-1 Radar is critical for the U.S. Navy’s aerial radar infrastructure and is a key component of Aegis Ballistic Missile Defense System at sea and on land. U.S. Navy cruisers and destroyers employ SPY-1—in addition to a number of foreign vessels—for Aegis Sea-Based BMD, while on land, the radar system is utilized by Aegis Ashore missile defense sites. Developed by Lockheed Martin, SPY-1 radar was originally designed as an air defense system, but has been upgraded to include a ballistic missile defense (BMD) capability. SPY-1’s passive electronic scanning system is computer controlled, using four complementary antennas in order to provide full 360 degree coverage. It operates in S-band and is a multi-function phased-array radar capable of search, automatic detection, transition to track, tracking of air and surface targets, and missile engagement support.

The SPY-1 can maintain continuous radar surveillance while automatically tracking more than 100 targets at one time. Public numerical figures on the SPY-1 detection range claim that it can detect a golf ball-sized target at ranges in excess of 165 km. When applied to a ballistic missile-sized target, the SPY-1 radar is estimated to have a range of 310 km. The system is designed for blue water and littoral operations however SPY-1 configuration must be modified to look above the terrain to avoid causing excessive false targets from land clutter. Configuration changes to mitigate this technical issue have made it more difficult for AN/SPY-1 to identify and track low and fast targets.

Regional Defense—Engagement Capability Aegis BMD systems are capable of detecting, tracking, targeting, and intercepting cruise and ballistic missile targets. After detecting and identifying a regional missile threat, Aegis BMD can engage and intercept the target using Standard Missile variants guided by tracking information provided by SPY-1. Aegis BMD-equipped cruisers and destroyers are being equipped with the capability to intercept short- and medium-range ballistic missiles as quickly as 10 seconds after the radar “sees” the missile’s movement.

Homeland Defense—Long-Range Surveillance and Tracking Aegis Destroyers on BMD patrol detect and track Intercontinental Ballistic Missiles with SPY-1, reporting tracking data to the Ballistic Missile Defense System (BMDS). The BMDS shares tracking data to cue other missile defense sensors and provides fire control data to Ground-based Mid-course Defense (GMD) interceptors located at Fort Greeley, Alaska and Vandenberg Air Force Base, California. To date, twenty-one Aegis Cruisers and Destroyers have been upgraded with the Long-Range Surveillance and Tracking capability. At-sea tracking events and flight tests have verified the capability to track Intercontinental Ballistic Missiles and demonstrated the connectivity and reliability of long-haul transmission of tracking data (across nine time zones), which is necessary to support missile defense situational awareness, target acquisition, and engagements.

Deployment Variants of the AN/SPY-1 radar are employed by all Aegis BMD systems, both on land—with Aegis Ashore—and at sea—on Ticonderoga (CG-47) Class Aegis Cruisers and Arleigh Burke (DDG-51) Class Aegis Destroyers. As of June 2015, there are 33 Aegis BMD-capable combatants in the U.S. Navy, 5 cruisers (CGs) and 28 destroyers (DDGs). Of the 33 ships, 16 are assigned to the Pacific Fleet and 17 to the Atlantic Fleet. U.S. allies with Aegis BMD-capable vessels, namely Japan, the Republic of Korea, Norway, and Spain also use the SPY-1.

SPY-1 radar employed by Aegis Ashore is virtually identical to that used by Aegis Sea-Based BMD. Currently, there is only one active Aegis Ashore site, which is located at the Deveselu Military Base in Romania, along with one under construction in Poland. There is an additional land-based test facility in Kauai, Hawaii.

SPY-1 Variants

Four different SPY-1 radar variants are currently deployed on U.S. ships. The original SPY-1 variant was a test version of the radar that was never deployed. The SPY-1A and 1B variants are equipped by Aegis cruisers and have two antenna faces on each of the two deckhouses, while the SPY-1D and 1D(V) variants are equipped by Aegis destroyers and have four antenna faces, each antenna covering slightly more than 90° in azimuth. All U.S. Aegis systems that have been upgraded for BMD are equipped with either the 1B, 1D, or 1D(V) version.

  • SPY-1A The SPY-1A was installed on the first Aegis cruiser, the USS Ticonderoga (CG 47), which was deployed in 1981. The U.S. Navy is currently in the process of phasing out the SPY-1A and most Aegis cruisers employ the upgraded 1B variant.
  • SPY-1B This SPY-1 variant has an improved antenna that is better suited to operate in a cluttered environment. The SPY-1B also has around twice the average power of the SPY-1A. 1B is currently employed by most Aegis cruisers.
  • SPY-1D The SPY-1D was the first SPY-1 radar developed for Aegis destroyers. This variant is similar to the 1B version, however, one transmitter is used by the 1D to drive all four radar faces, which are all located on a single deckhouse. This upgrade also improves the radar’s performance against low-altitude, reduced radar cross-section targets in heavily cluttered environments and in the presence of electronic countermeasures. The four U.S. destroyers based in Rota, Spain in 2015 as part of the European Phased Adaptive Approach (EPAA) are equipped with SPY-1D radar.
  • SPY-1D(V) Called the “littoral warfare” radar, the SPY-1D(V) improved clutter rejection and moving target detection, enhancing the capability of Aegis radar in cluttered environments.
  • SPY-1F This variant—known as the “frigate array radar system”—is designed for Aegis frigates and is a smaller version of the SPY-1D. While not employed by the U.S. Navy, the SPY-1F is used by Norway on their Fridtjof Nansen-class Aegis frigates.

Thales Sirius LR-IRST long-range dual-band infrared search and track systems (?)


Thales Naval Nederland Sirius LR-IRST long-range dual-band infrared search and track systems This is a high-powered Infra Red surveillance system. It is very useful for locating sea-skimming missiles. It is designed and build by Thales. Sirius is a dual-band IR detection and tracking sensor with an 8-12 micron and a 3-5 micron IR camera on a pedestal. The former has a window which elevates to 14 degrees and the latter a window which elevates to 3 degrees. Scan rate is 53 rpm and an airplane can be detected at up to 15km, a missile at up to 12km. The system can carry over 500 tracks and provides automatic alerts on the 32 most threatening tracks with a false alarm rate of less than 1/hr. SIRIUS provides data directly to the SEWACO Combat Data System as digital data to the databus and video to the video bus. Each band can be processed separately providing three different outputs – each band individually or a combined output.




The AN/SPS-67 is a two-dimensional pulsed radar set primarily designed for surface search and navigation, and limited air search capability. It can also detect antiship-missiles (ASM) and low-flying aircraft. The AN/SPS-67 is a successor to the AN/SPS-10.

The AN/SPS-67(V)3 antenna consists of an L-band IFF- monopulse array antenna integrated atop a C-band feed horn array antenna using horizontal linear polarisation. Its nominal elevations beam width is 28 degrees.

Below-decks, AN/SPS-67 consists of a transceiver, a video processor, a radar control unit, an antenna controller and an antenna safety switch, all of which are housed in five cabinets. System performance is improved via the addition of a very narrow pulse mode (0.1 µs) for better navigation and improved resolution of small targets at short ranges. Long and medium pulse (1 and 0.25 µs) modes are used in open sea for detection of long- and medium-range targets.

The Radar Set AN/SPS-73(V)12 is a short-range, two-dimensional, surface search/navigation radar system that provides contact range and bearing information. The AN/SPS-73(V)12 provides for signal processing and automatic target detection capability. The AN/SPS-73(V)12 surface search function provides short-range detection and surveillance of surface units and low-flying air units, while the AN/SPS-73(V)12 navigation function enables quick and accurate determination of own ship position relative to nearby vessels and navigational hazards. The system’s radar processors and displays combine Commercial-Off-The-Shelf (COTS) products and specialized technologies to create navigational awareness. The AN/SPS-73(V)12 is replacing the AN/SPS-64(V) and AN/SPS-55(V) systems in their capacity as navigational radars on the US Navy Ships.

The AN/SPS-73(V) radar has Built-In-Test functionality for improved reliability, capability and maintainability. The AN/SPS-73(V) can track up to 200 targets on a single system or 300 targets on a dual system with speeds up to 210 knots. The AN/SPS-73(V) Radar tracks surface crafts, obstructions, shorelines, buoys and navigational markers in order to assist in navigation, collision avoidance, surface surveillance and limited detection of low flying aircraft. The AN/SPS-73(V) is designed to commercial standards for navigation radars and is in compliance with various electronics interfacing standards (e.g., NMEA 0183). This radar system is a digital system, which outperforms the previous analog AN/SPS-64(V) Radar. The system can be easily integrated with other navigation and information processing systems, such as AIS, Electronic Chart Display Information System-Navy (via IBS) and Navigation Sensor System Interface. The AN/SPS-73(V) system can also be modified to accommodate future interfaces and requirements; the systems’ Interface Design Document describes the data, status, and control inputs and outputs of the radar and facilitates integration into other systems.

The hull-mounted sonar is the Raytheon DE1160 LF active and passive sonar. The Sikorsky SH-60 Seahawk helicopter is equipped with AN/SQQ-28 LAMPS III sonobuoys.

Raytheon DE1160 LF active and passive sonar


The DE 1160 is known as the DE 1164 when configured as a Variable-Depth Sonar (YDS). As a YDS, the sonar can descend to 656 ft (200 m) and be towed at speeds up to 20 knots.
The DE 1160 is capable of convergence zone performance when equipped with three additional transmitter cabinets (for a total of eight) and a larger, low-frequency transducer array. This configuration, which is fitted to the Italian aircraft carrier Giuseppi Garibaldi, is known as the DE 1160LF. The DE 1160LF/VDS combines the capabilities of the 1160LF with the VDS ability to adapt to the environment of the DE 1164.

The 1167 is smaller and less expensive. The sonar can be fitted in a hull dome or deployed as a VDS, or as an integrated hull dome and VDS. The VDS transmits at 12 kHz and the 36-stave circular, hull-mounted array transmits at either 12 or 7.5 kHz. Source
