In November 1989, the Australian / New Zealand frigate building project contracted Australian shipbuilders Tenix Defence Systems to construct ten Anzac Class frigates; eight for Australia and two for New Zealand. The first frigate for the Royal Australian Navy (RAN), HMAS Anzac, was commissioned in May 1996.
The other hulls are: HMAS Arunta (FFH 151), commissioned December 1998; HMAS Warramunga (FFH 152), March 2001; HMAS Stuart (FFH 153), August 2002; HMAS Parramatta (FFH 154), October 2003; HMAS Ballarat (FFH 155), June 2004; HMAS Toowoomba (FFH 156), October 2005; HMAS Perth (FFH 157), August 2006. The two frigates for New Zealand, HMNZS Te Kaha (F77) and Te Mana (F111), were commissioned in July1997 and December 1999.

Anzac Class frigate construction and development
Tenix Defence Systems (now part of BAE Systems Australia) is the prime contractor, with responsibility for design and systems integration of the ship; subcontractor Blohm + Voss Australia provides the platform design and combat system integration; and Saab Systems Australia provides electronic integration and combat system design.
HMAS Warramunga (FFH 152)
The 3,600t frigates were built at Tenix’s Williamstown yard in Victoria, Australia. The design is based on the Blohm + Voss Meko 200 modular design which utilises a basic hull and construction concept to provide flexibility in the choice of command and control, weapons, equipment and sensors.
HMAS Anzac (FFH 150)
In March 2003, HMAS Anzac was deployed in support of coalition forces in Operation Iraqi Freedom. Both of the New Zealand frigates were deployed in support of Operation Enduring Freedom.
In February 2010, a major upgrade to the Royal New Zealand Navy (RNZN) frigate Te Kaha was completed. In December 2010, The RNZN frigate Te Mana returned to service after a seven-month refit programme. Both frigates were fitted with new diesel engines for improved performance and reduced fuel costs.

Weapons control is managed by the Saab Systems 9LV 453 optronic director with Saab Systems J-band radar. Raytheon CW mk73 is the fire control system for the Sea Sparrow missile. This has been replaced with the CEA Technologies I/J-band solid-state continuous-wave illuminator transmitter (SSCWI) on Warramunga and will be fitted to all Anzac vessels.
CEA Technologies I/J-band solid-state continuous-wave illuminator transmitter (SSCWI)
CEA SOLID STATE CONTINUOUS WAVE ILLUMINATOR (SSCWI) TRANSMITTER
CEA SSCWI is a solid state transmitter, suitable for use with semi-active homing surface to air missiles including Evolved Sea Sparrow Missile (ESSM). Available in high and medium power versions for ships of varying sizes, the SSCWI’s core solid state technology and hardware control interface provides.
- enhanced performance
- equipment size reduction
- improved maintainability and reliability.
The Anzac is armed with one eight-cell mk41 vertical launching system for Nato Sea Sparrow surface-to-air missiles. Sea Sparrow is a semi-active radar missile with a range of 14.5km.
The MK 41 Vertical Launching System (VLS) is the worldwide standard in shipborne missile launching systems. Under the guidance of the US Navy, Martin Marietta performs the design, development, production, and field support that make the battle-proven VLS the most advanced shipborne missile launching system in the world. The Mk 41 VLS simultaneously supports multiple warfighting capabilities, including antiair warfare, antisubmarine warfare, ship self-defense, strike warfare, and antisurface warfare.
The Vertical Launching System (VLS) Mk 41 is a canister launching system which provides a rapid-fire launch capability against hostile threats. The missile launcher consists of a single eight-cell missile module, capable of launching SEASPARROW missiles used against hostile aircraft, missiles and surface units. Primary units of the VLS are two Launch Control Units, one 8-Cell Module, one 8-Cell System Module, a Remote Launch Enable Panel and a Status Panel.
The Launch Control Units receive launch orders from the Multi-Function Computer Plant (MFCP). In response to the orders, the Launch Control Units select and issue prelaunch and launch commands to the selected missile in the VLS launcher. During normal VLS operations, each Launch Control Unit controls half of the Launch Sequencers in the launcher. Either Launch Control Unit can be ordered by the MFCP where one Launch Control Unit is offline and the other Launch Control Unit assumes control of all Launch Sequencers in the launcher.
The 8-Cell Module consists of an upright structure that provides vertical storage space for eight missile canisters. A deck and hatch assembly at the top of the module protects the missile canisters during storage and the hatches open to permit missile launches. The plenum and uptake structure capture and vent missile exhaust gases vertically up through the module to the atmosphere through the uptake hatch. Electronic equipment mounted on the 8-Cell Module monitors the stored missile canisters and the module components and assists in launching the missiles.
“quad pack” launcher (Mk-41 VLS)
Sea Sparrow has been replaced by the evolved Sea Sparrow missile (ESSM) in HMAS Warramunga, Stuart and Parramatta, increasing the capacity from eight to 32 missiles, and the weapon system was declared operational on these vessels in June 2004. ESSM will be retrofitted in the first two Australian ships. HMAS Warramunga was the first vessel in the world to be fitted with the ESSM.
Evolved Sea Sparrow missile (ESSM)
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.
ESSM is a cooperative effort among 10 of 12 NATO Sea Sparrow nations governed by a Production Memorandum of Understanding (MOU) and multinational work-share arrangement. In addition to the United States, ESSM Consortium Members include Australia, Canada, Denmark, Germany, Greece, The Netherlands, Norway, Spain, and Turkey.
The first production ESSM was delivered in late 2002 to the U.S. Navy by Raytheon Missile Systems (RMS) and has been in full operational use in the U.S. since 2004. ESSM is fired from the Mk-29 trainable launcher, Mk-41 Vertical Launch System (VLS), Mk-57 VLS (DDG 1000), Mk-48 Guided Missile VLS (Canadian, Greece, Japan), and Mk-56 Dual Pack ESSM Launching System (Danish Navy) configurations by the U.S. Navy, NATO, and other Foreign Military Sales (FMS) customers. ESSM interfaces with the Aegis (DDG 51 and CG 47 classes), NSSMS (LHD and CVN classes), Ship Self-Defense System (LHA-6 and future CVN classes), Total Ship Computing Environment (DDG 1000), ANZAC (Royal Australian Navy), Dutch Configuration (various European Navies), FLEXFIRE (Danish Navy), and APAR (various European Navies) combat systems.

ESSM has been developed by Raytheon with an international cooperative of ten Nato countries and is designed to counter high-speed anti-ship missiles. It has the same semi-active radar guidance and warhead as the Seasparrow but has a new rocket motor and tail control to provide increased speed, range and manoeuvrability. ESSM was passed for full-rate production by the US Navy in April 2004.
Capacity to launch eight Boeing Harpoon block II anti-ship missiles has been added under project SEA 1348 Phase 3A. First vessel to receive the Harpoon launcher was Warramunga in December 2004. Seven vessels have received the modification and the eighth, Perth, was completed in September 2008. Harpoon Block II missiles have new inertial / GPS (global positioning system) guidance for precision targeting.
Harpoon block II anti-ship missile
The Harpoon missile provides the Navy and the Air Force with a common missile for air, ship, and submarine launches. The weapon system uses mid-course guidance with a radar seeker to attack surface ships. Its low-level, sea-skimming cruise trajectory, active radar guidance and warhead design assure high survivability and effectiveness. The Harpoon missile and its launch control equipment provide the warfighter capability to interdict ships at ranges well beyond those of other aircraft.
The Harpoon missile was designed to sink warships in an open-ocean environment. Other weapons (such as the Standard and Tomahawk missiles) can be used against ships, but Harpoon and Penguin are the only missiles used by the United States military with anti-ship warfare as the primary mission. Once targeting information is obtained and sent to the Harpoon missile, it is fired. Once fired, the missile flys to the target location, turns on its seeker, locates the target and strikes it without further action from the firing platform. This allows the firing platform to engage other threats instead of concentrating on one at a time.
The Guidance Section consists of an active radar seeker and radome, Missile Guidance Unit (MGU), radar altimeter and antennas, and power converter. The MGU consists of a three-axis attitude reference assembly (ARA) and a digital computer/power supply (DC/PS). Prior to launch, the DC/PS is initialized with data by the Command Launch System. After launch, the DC/PS uses the missile acceleration data from the ARA and altitude data from the radar altimeter to maintain the missile on the programmed flight profile. After seeker target acquisition, the DC/PS uses seeker data to guide the missile to the target.
The Warhead Section consists of a target-penetrating, load-carrying steel structure containing 215 pounds of high explosive (DESTEX) and a safe-and-arm/contact fuze assembly. The safe-and-arm/contact fuze assembly ensures the warhead will not explode until after the missile is launched. It is designed to explode the warhead after impacting the target. The warhead section can be replaced by an exercise section which transmits missile performance data for collection and analysis.
The Sustainer Section consists of a fuel tank with JP-10 fuel, air inlet duct, and a jet engine. This provides the thrust to power the missile during sustained flight. The Sustainer Section has four fixed fins which provide lift.The Control Section consists of four electromechanical actuators which use signals from the Guidance Section to turn four fins which control missile motion.
The Booster Section consists of a solid fuel rocket and arming and firing device. Surface and submarine platforms use a booster to launch Harpoon and propel it to a speed at which sustained flight can be achieved. The Booster Section separates from the missile before sustained flight begins.
The Harpoon Block II is an upgrade program to improve the baseline capabilities to attack targets in congested littoral environments. The upgrade is based on the current Harpoon. Harpoon Block II will provide accurate long-range guidance for coastal, littoral and blue water ship targets by incorporating the low cost integrated Global Positioning System/Inertial Navigation System (GPS/INS) from the Joint Direct Attack Munitions (JDAM) program currently under development by Boeing. GPS antennae and software from Boeing’s Standoff Land Attack Missile (SLAM) and SLAM Expanded Response (SLAM ER) will be integrated into the guidance section. The improved littoral capabilities will enable Harpoon Block II to impact a designated GPS target point. The existing 500 pound blast warhead will deliver lethal firepower against targets which include coastal anti-surface missile sites and ships in port. For the anti-ship mission, the GPS/INS provides improved missile guidance to the target area. The accurate navigation solution allows target ship discrimination from a nearby land mass using shoreline data provided by the launch platform. These Block II improvements will maintain Harpoon’s high hit probability while offering a 90% improvement in the separation distance between the hostile threat and local shorelines. Harpoon Block II will be capable of deployment from all platforms which currently have the Harpoon Missile system by using existing command and launch equipment. A growth path is envisioned for integration with the Vertical Launch System and modern integrated weapon control systems. With initiation of engineering and manufacturing development in 1998, initial operational capability for Block II will be available by 2001. Source fas.org

The main gun is a BAE Systems Land & Armaments (formerly United Defense) 127mm mk45 mod 2 gun, which can fire at a rate of 20 rounds a minute to a range of over 20km.
127mm mk45 mod 2 gun
The 127mm Mk 45 is a naval gun turret of US origin. It was developed in the 1960’s by United Defense as a lighter alternative to the earlier Mk 42 turret. The Mk 45 is the smallest 127mm gun turret in the world and can be considered a direct competitor to the Italian 127mm Compatto. The Mk 45 is a lighter and easier to install design while the Compatto has a higher rate of fire and has more ammunition ready to fire. Both guns use the same US standard 127mm ammunition.
The Mk 45 is a single gun turret which is armed with the 127mm Mk 19 gun which was derived from the earlier Mk 18 that was used in the older Mk 42 turret. The Mk 45 is an unmanned turret with an automatic loader and a 20 round magazine below deck. Additional rounds are stored elsewhere in the ship and fed into the magazine using a feed chute. The gun is controlled using consoles below deck or in the command center. The latest development are a longer barrel and extended range guided munition (ERGM), the latter program was cancelled while the new barrel is in production.
The Mk 45 fires 127mm shells for use against shore targets, naval vessels and aircraft. The gun has a rate of fire of 16 to 20 rounds per minute. The maximum range is 23 km versus surface targets and the anti-aircraft range is quoted as 15 km. The latest Mk 45 design with longer barrel has a longer range and higher rate of fire. The ERGM round has a range of 117 km but was never fielded. Depending on the ship design the total ammunition load ranges between 475 and 680 rounds
The Mk 45 turret can be easily distinguished from the earlier Mk 42 turret by its shape and longer ordnance. The Mk 45 is one of the smallest 127mm gun turrets. The Mk 45 guns with original 54-caliber barrel can be identified by their round turret shapes since the Mod 4 uses an angled one.
Mk 45 Mod 0: Original production model with mechanical fuze setter and two piece barrel.
Mk 45 Mod 1: Improved Mod 0 with automatic fuze setter and unitary barrel.
Mk 45 Mod 2: Export version of US Navy Mod 1.

HMAS Perth (FFH 157)
The frigate is equipped with Thales Defence Sceptre A radar warner. Decoy systems consist of SLQ-25A towed torpedo decoys and mk36 launchers, initially for Sea Gnat decoys but now used to launch BAE Systems Australia Nulka anti-missile hovering offboard decoy, which provides protection against radio frequency seeker anti-ship missiles.
SLQ-25A towed torpedo decoys
The AN/SLQ-25A/C is a digitally controlled modular electro-acoustic softkill countermeasure decoy system that employs an underwater towed body acoustic projector deployed from the ship’s stern on a fiber optic tow cable to defend ships against wake-homing, acoustic homing, and wire-guided enemy torpedoes.
The AN/SLQ-25 is deployed on U.S. and allied surface warships, and consists of the TB-14A towed decoy device and a shipboard signal generator. The decoy emits signals to draw incoming torpedoes away from their intended targets.
TB-14A towed decoy device
The AN/SLQ-25 towed decoy emits simulated ship noise like the sounds of propellers and engines in attempts to defeat a torpedo’s passive sonar.
The AN/SLQ-25A uses a fiber optic tow cable and winch, and includes extensive use of commercial off-the-shelf (COTS) components. The AN/SLQ-25C is an upgrade to the AN/SLQ-25A, and includes new countermeasure modes and a longer tow cable.
The BAE Systems Mark 36 Super Rapid Bloom Offboard Countermeasures Chaff and Decoy Launching System (abbreviated as SRBOC or “Super-arboc”) is a short-range mortar that launches chaff or infrared decoys from naval vessels to foil anti-ship missiles. Each launcher has three tubes set at a 45-degree angle, and three tubes set at a 60 degree angle, providing an effective spread of decoys and countermeasures to defeat radio frequency emitting missiles. The SRBOC can also be fitted with the TORCH infrared “flare” decoy system. A typical ship’s load is 20 to 35 rounds per launcher.
Nulka anti-missile hovering offboard decoy
Nulka is an active, off-board, ship-launched decoy developed in cooperation with Australia to counter a wide spectrum of present and future radar-guided anti-ship cruise missiles (ASCMs).
The Nulka decoy employs a broadband radio frequency repeater mounted atop a hovering rocket platform. After launch, the Nulka decoy radiates a large, ship-like radar cross-section while flying a trajectory that seduces and decoys incoming ASCMs away from their intended targets. Australia developed the hovering rocket, launcher, and launcher interface unit. The U.S. Navy developed the electronic payload and fire control system.
The existing Mk 36 Decoy Launching System (DLS) has been modified to support Nulka decoys, resulting in the Mk 53 DLS. Nulka has been developed under a U.S. Australian cooperation. It is been used on board U.S. and Australian surface warships since 1999.
Air search is by Raytheon SPS-49(V)8 ANZ radar, operating at C/D band, and air / surface search by Sabb Microwave Systems (formerly Ericsson) Sea Giraffe G/H-band radar. The I-band navigation radar is the Atlas Electronik 9600 ARPA.
Raytheon SPS-49(V)8 ANZ radar
The AN/SPS-49 long range 2-dimensional air surveillance radar used for early target detection. The long-range AN/SPS-49 radar operates in the presence of clutter, chaff, and electronic counter-measures to detect, identify, and control low-radar-cross-section threats traveling at supersonic speeds. AN/SPS-49 provides the front-end element for successful target identification, designation, and engagement with either long range (SM-1 or SM-2) missiles and/or short range local defense missiles. A key feature of the most recent version of the radar, the SPS-49A(V)1 is single-scan radial velocity estimation of all targets allowing faster promotion to firm track and improved maneuver detection. This is done using unique signal processing techniques originated and tested by the Radar Division of NRL using 6.1 and 6.2 Office of Naval Research (ONR) funds.
The AN/SPS-49(V) radar is a narrow beam, very long range, 2D air search radar that primarily supports the AAW mission in surface ships. The radar is used to provide long range air surveillance regardless of severe clutter and jamming environments. Collateral functions include air traffic control, air intercept control, and antisubmarine aircraft control. It also provides a reliable backup to the three-dimensional (3D) weapon system designation radar.

The AN/SPS-49(V) radar operates in the frequency range of 850 – 942 MHZ. In the long range mode, the AN/SPS-49 can detect small fighter aircraft at ranges in excess of 225 nautical miles. Its narrow beamwidth substantially improves resistance to jamming. The addition of coherent side lobe canceller (CSLC) capability in some AN/SPS-49(V) radars also provides additional resistance to jamming/interference by cancelling the jamming/interference signals. The moving target indicator (MTI) capability incorporated in the AN/SPS-49(V) radar enhances target detection of low-flying high speed targets through the cancellation of ground/sea return (clutter), weather and similar stationary targets. In 12 RPM mode operation, this radar is effective for the detection of hostile low flying and “pop-up” targets. Features of this set include:
- Solid state technology with modular construction used throughout the radar, with the exception of the klystron power amplifier and high power modulator tubes
- Digital processing techniques used extensively in the automatic target detection modification
- Performance monitors, automatic fault detectors, and built-in-test equipment, and automatic on line self test features

Kelvin Hughes SharpEyeTM I-Band
SHARPEYE™ SOLID STATE PULSE DOPPLER RADAR
SharpEye™ I-Band and E/F-band (X & S-band) radar technology meets the detection challenges of navies, coastguards and border agencies through a clever combination of radar techniques designed to provide the best performance in all conditions, whilst also providing the flexibility to be optimised for specific detection needs.
Solid state radar ensures extremely high reliability and low through life cost:
- No magnetron – minimal routine maintenance requirements
- No fault-finding training required
- Line replaceable unit – does not require radar trained technician to replace
- Low Mean Time To Repair (MTTR)
- Upmast transceiver solution – no waveguide to compromise citadel integrity – easy to retrofit – reduced signal loss.
SharpEye™ transmits a low power patented pulse sequence, which enables short, medium and long range radar returns to be detected simultaneously, allowing the radar operator to maintain situational awareness regardless of the range scale setting of the radar display. Other users of the radar can select their own radar display range scale. A low peak transmission power (less than 300W) equivalent to a 25kW magnetron reduces the probability of intercept by ESM systems.
Doppler processing of radar returns provides coherent information concerning a target’s velocity (radial) and enable the detection of very small and slow moving objects and targets with a low RCS (Radar Cross Section) and through a series of electronic filters is able to distinguish between the targets of interest and sea, rain and land clutter.
SharpEye™ I-Band (X-Band) transmitters are the first in their class to employ Gallium Nitride GaN power transistor technology. The significant performance benefits of GaN transistors have been harnessed to directly improve the performance of the radar.
Other differentiating technologies include Moving Target Detection (MTD) providing enhanced clutter suppression at the Doppler processing stage and pulse compression of the return signal, enabling a low transmit power, providing efficient use of the radar and reducing the probability of detection by ESM equipment. Other Doppler radars may employ less advanced techniques such as Moving Target Indication (MTI), which does not take full advantage of the radial velocity information.

Customisable waveforms can be configured for specific threats and to track specific targets such UAVs, drones and helicopters. SharpEye™ is a truly multipurpose naval radar transceiver:
- Surface search
- Helicopter control and recovery (no need for helicopter transponders, even over land)
- Camera slew to cue
- Bi-directional links to combat management system
- Uniform transmission on all ranges so that multiple users on different range scales all see the optimum picture
- Frequency diversity, user selectable frequencies to ensure interoperability

Initially, the ASMD capability is being fitted in a single ship, HMAS Perth, prior to other Anzac vessels being modified. HMAS Perth began fitting out in January 2010. Initial operational capability for the ASMD started in 2011, followed by an operational evaluation period of 12 months.
In April 2009, Saab signed a continuation funding contract for progress of SEA 1448 phase 2 project of the Anzac frigates in Australia. The project will cost $840m. Under the project, Saab will integrate CEA Technologies radar and new navigation radars into the HMAS Perth. The funding for the lead ship was approved by the government and the project commenced in January 2010. This upgrade replaced the Saab Microwave Systems Sea Giraffe G/H-band radar. The contract also includes additional funding for implementation of an improved operations room design with additional air warfare capabilities of the ship.
Saab Systems, Defence Material Organisation and Tenix (now a part of BAE Systems) signed a three-way partnerhsip contract for enhancement and maintenance of the frigates in April 2007. This contract would replace the Anzac ship alliance that handled capability generation and the in-service support contract that handled capability sustainment. The contractual scope includes nine years of support with provision for extension for six more years.
Under the SEA 1448 phases 2A and 2B ASMD project, the team completed the final reviews for the mk3E combat management system in August 2008; received the first phased array radar faces and control equipment in June 2009; and completed HMAS Perth’s new FWD and AFT masts.
Further upgrades are scheduled under the joint project 2089 phase 2A (tactical information exchange domain) and Project SEA 1442 phase 4 (maritime communications modernisation).
Each ship is designed to accommodate, operate and maintain its own helicopter. The RAN is using its Sikorsky Seahawk S-70B2s initially but ordered 11 Kaman SH-2G Super Seasprite helicopters.

Deliveries began in 2001 and the SH-2G(A) received provisional acceptance into service in October 2003.
The helicopters were grounded in May 2006, after problems with the flight control system and ITAS software. A review of the programme was initiated in May 2006 and, in May 2007, the RAN decided to continue with the project rather than pursue alternatives.
However in March 2008, the RAN finally announced the cancellation of the programme. The helicopters were returned to Kaman for possible sale.
The RNZN ordered five SH-2Gs, two for the Anzac frigates. Deliveries completed in March 2003 and all five have entered service. These are armed with the Raytheon Maverick missile.
