From ultra-long range radar systems to integrated satellite communications, the Navy operates some of the most advanced IT systems in the world. When your people are spread across the oceans of the world, and possibly in hostile situations, you need advanced equipment to keep in contact and control.
The operation of the Combat System in ships is the responsibility of Combat Systems Operators. All Combat Systems Operators operate sensor equipment such as Radar and can specialise in either Electronic Warfare or Sonar Operation. Learn More
The Navy’s ships and aircraft are equipped with an array of different radar equipment. Radar uses radio waves to determine and map the location, direction, and/or speed of both moving and fixed objects such as aircraft, ships and terrain. A transmitter emits radio waves, which are reflected by the target and detected by a receiver. The distance to an object can be worked out by the time it takes between a signal being sent and a return echo received. The time gap between the sent signal and the return echo will reveal the distance the sound has travelled.
To measure a moving object’s speed, a radar can use a phenomenon known as Doppler shift. When a signal is reflected from a moving object, the length of the signal will change according to the speed and direction of that object. Here is an example of combining the echo and doppler shift: Say you send out a loud sound directed at a car moving toward you. Some of the sound waves will bounce off the car (an echo), however because the car is moving toward you, the sound waves will be compressed. Therefore, the sound of the echo will have a higher pitch than the original sound you sent. If you measure and compare the pitch of the echo to the original, you can determine how fast the car is going.
There’s an exciting career on the radar. As a Combat Systems Operator in the Navy, you will travel throughout Australia and overseas whilst working in a team environment. Learn More
Sonar is a similar technique to radar but instead uses sound waves to travel through water to locate submerged objects. There are 2 types of sonar used, active and passive.
Active sonar emits pulses of sound waves, often called a "ping", that travel through the water, reflect off the target and return to the ship. By knowing the speed of sound in water and the time for the sound wave to travel to the target and back, the computers can quickly calculate distance between the emitter and the target. Whales, dolphins and bats use the same technique for locating prey.
An Acoustic Warfare Analyst (AWA) operates, supervises and manages all passive and active acoustic sensors and sonars onboard a Collins Class Submarine. An AWA is trained to detect, track and classify noise sources found in the oceans. Learn More
The use of submarines and effective anti-submarine tactics is one of the most important aspects of Australia’s Naval Operations. As an Acoustic Warfare Analyst you will be operating advanced Sonar and Combat Systems to contribute to the mission of the submarine. Learn More
A Collins Submarine will use passive sonar to listen to sounds generated by other objects such as Ships or other Submarines. Using this technique, it can know the location of the sound’s origin but keep its own position secret. The role of classifying sounds to know what vessel is detected is conducted by expert sonar operators called Acoustic Warfare Analysts who are trained, and experienced, in using automated systems to assist them in identifying all sounds particularly those from targets of interest or threat weapons.
The Navy’s ANZAC Frigates operate the Harpoon anti-ship missile. It is a low altitude, guided missile that flies with the use of a turbojet engine. By using its GPS navigation and a data-link back to the ship, its guidance can be adjusted mid-course.
Torpedoes are carried by the Navy’s Aircraft, surface fleet and Submarines. Used against surface or underwater vessels, they have fast motorised propulsion and an internal guidance system that will direct them towards their target.
Located at the front of an ANZAC Frigate, the 5 inch gun is a powerful weapon capable of firing shells accurately over distances up to 24km.
