HMA Ships Newcastle and Warramunga conducted missile firings on the Pacific Missile Range Facility
HMA Ships Newcastle and Warramunga conducted a SAMEX on the Pacific Missile Range Facility (PMRF) to test the operation of integrated multi-ship defence against multiple targets with SM-2, Evolved Sea Sparrow Missile (ESSM), Nulka and Chaff. Realistic targets (BQM-74E) representing a regional subsonic ASM were used.

Testing was conducted during Rim of the Pacific (RIMPAC) 2010 Exercises, Hawaii.
The Australian Defence Force’s largest international maritime exercise, Exercise Rim of the Pacific (RIMPAC) is designed to test interoperability with 14 Pacific Rim nations.
Approximately 1200 ADF personnel will be participating.

This year marks the 22nd RIMPAC. It is being hosted by the US Third Fleet over a five week period, finishing on the 1st August 2010.

Standard Missile-2 (SM-2) is the world’s premier surface-to-air defense weapon. Its primary mission is fleet-area air defense and ship self-defense, but it has also demonstrated an extended-area air defense projection capability.
The SM-2 also has a secondary anti-surface ship mission, and it uses tail controls and a solid-fuel rocket motor for propulsion and maneuverability. In addition, the extended-range missile has a booster with thrust vector controls. The SM-2 is guided by inertial navigation and midcourse commands from the weapon control system and by semi-active radar, or an IR sensor, for terminal homing.
SM-2 intercepts are accomplished through the use of inertial midcourse guidance (Tartar) and command midcourse guidance (Aegis) with the missile employing an electronic attack (EA) jamming resistant monopulse receiver for semi-active radar terminal guidance. The Tartar and Aegis flight profiles allow the missile to approach the target without the need for a shipboard illuminator until the terminal homing phase.
Target updates are provided through the weapon-fire control system for Tartar missiles, while command guidance is accomplished via a link for Aegis missiles.
Midcourse guidance offers the significant advantage of increased firepower and the ability to engage smaller targets at extended ranges via delayed target acquisition and terminal homing. SM-2 is compatible with the MK 13 and MK 26 rail launchers and the MK 41 Vertical Launching System.
Blocks IIIA and IIIB
The current generation of SM-2, Blocks IIIA and IIIB, capitalizes on communication techniques, midcourse guidance, advanced signal processing and propulsion improvements. These enhancements substantially increase the intercept range and provide high- and low-altitude intercept capability and performance against advanced anti-ship missile threats.
The SM-2 Block IIIB configuration incorporates a side-mounted imaging infrared seeker into the proven Standard Missile guidance system. This sensor significantly improves the missile’s terminal engagement performance against stressing anti-ship missile threats.
The current versions of both the SM-2 Block IIIA and the SM-2 Block IIIB also have enhanced maneuverability and a state-of-the-art Target Detecting Device that maintain the missile’s excellent performance against all threats.

The Evolved SeaSparrow Missile (ESSM) defends the local area battlespace, delivering lethal, quick reaction firepower against faster, lower, smaller and more maneuverable anti-ship threats, including cruise missiles, surface threats and low-velocity air threats. ESSM Advances Modern fleets require an agile counter to the evolving threats that endanger today’s navies.
ESSM meets the challenge with fast, maneuverable, long-range performance; a guidance section capable of targeting smaller threats; and a warhead that is lethal against hardened targets. ESSM is a tail-controlled missile with maneuverability throughout the flight envelope and thrust vector control for quick pitchover after vertical launch. ESSM’s state-of-the-art fuze maximizes lethality against low-altitude, low cross section threats. ESSM requires no prelaunch warm-up and is ready for engagement at all times.
ESSM is designed with the broadest degree of system compatibility in mind. It is
integrated into a wide variety of combat systems including the Aegis, NATO SeaSparrow Surface Missile System U.S. and Dutch configurations, APAR (Active Phased Array Radar), Stanflex and Anzac. ESSM can be loaded in a quad-pack canister for the MK 41 and MK 57 vertical launch systems, or a dual-pack canister for the MK 56 vertical launch system.
Both canister configurations offer a significant increase in load-out capacity and firepower for naval combatants. ESSM can also be loaded into a single pack for the MK 29 trainable and MK 48 vertical launchers.
ESSM’s design exploits modern missile control technology to counter emerging ship defense threats. ESSM can employ inertial midcourse, command midcourse or home-all-the-way guidance. For terminal guidance, ESSM supports conventional continuous wave illumination or interrupted continuous wave illumination-sample data homing guidance used by multifunction radars. Both S-band and X-band data links communicate with capable combat systems.
