Integrated Sonar System (ISS)

Ultra’s modular Integrated Sonar System delivers a fully integrated, flexible, networked Anti-Submarine Warfare (ASW) solution. This ground-breaking system is inherently designed to maximise the performance from its underwater sensors; all sensors (e.g. Hull-Mounted Sonar , Variable Depth Sonar) are processed simultaneously as multiple-inputs to a single signal processing suite, rather than processing each sensor separately and fusing contacts. This delivers significant performance enhancements over traditional systems. Furthermore, the ISS is able to operate bi-statically by processing active sonar transmissions from the Hull Mount Sonar via the receive array from the Variable Depth Sonar, and vice-versa providing enhanced coverage above and below the “layer”.

The ISS option can also include a multi-statics module that further increases its detection performance by allowing it to utilise off-board sensors, such as Remotely Deployable Sensors, active and passive Sonobuoys, as well as the active sonar transmissions from an ISS installed on a co-operating vessel. The first system is currently being delivered to the Royal Australian Navy for installation on their newest vessel, the Hobart Class Air Warfare Destroyer.

The ISS is developed in accordance with the highest levels of open architecture standards and is a core component of Ultra’s Software Configurable Sonar.


Surface Ship Torpedo Defence (SSTD) System 'Sea Sentor'

For surface ship torpedo defence, Ultra's Sea Sentor system delivers a single in-line towed array solution utilising a passive tow for detection, classification and localisation of the threat. The system features a flexible towed body countermeasure able to decoy and jam all torpedoes types, including wake-homing torpedoes, and optional launchers can deliver expendable countermeasures.

Submarine Torpedo Defence System

Ultra is the only company to have delivered sensor-to-countermeasure capability into service on multiple platforms for disparate navies. The comparable submarine torpedo defence solution Sea Crypsis also makes use of the latest generation of mobile torpedo countermeasures.

Further offerings are Active DCL, Passive DCL, torpedo hard kill countermeasures and torpedo soft kill countermeasures.

Airborne ASW Sonar Systems

The Ultra Multi-Static Active System (MSA) comprises a field of transmit and receive sonobuoys and the necessary processing to detect and track targets without overloading the operator. The system uses combinations of the following buoy types, all of which are
available from Ultra with embedded GPS for precision operation:

- SSQ 926 ALFEA Electro-Acoustic Source
- SSQ 955 HIDAR High Dynamic Range DIFAR
- SSQ 981E Barra (Horizontal Planar Array)

In another specialised sonar field, using high resolution Synthetic Aperture Sonar (SAS), Ultra provides high speed coverage for mine detection and oceanographic survey. Featuring co-located high resolution swath bathymetry and sidescan imagery. The system can be hull-mounted, towed or packaged for autonomous and remotely operated vehicles.

The Ultra Forward Look Sonar (FLS) complements the SAS system by dramatically increasing coverage rates. It has further stand-alone applications in obstacle avoidance and mine detection.

Mine disposal system SEAFOX

SEAFOX is an expendable remotely-operated underwater vehicle which uses a shaped charge warhead to neutralise the target mine. Operated from a shipboard console, with communications from the console to the vehicle sensors via a fibre-optic cable, SEAFOX uses its own onboard guidance and navigation system to acquire and prosecute the target.

Teamed with Atlas Elektronik and Babock Engineering Services, Ultra was selected as prime contractor for the delivery of SEAFOX to the Royal Navy as their one-shot mine disposal system.

Submarine communications at speed and depth

Ultra’s pedigree in submarine communications is evidenced by its ability to offer potential solutions to all the technology requirements of the Communications at Depth programme. This includes various tethered (RTOF) and expendable communication buoys (ETOF), and a new submarine paging system which again demonstrates Ultra's ability to leverage core skills in acoustics technology.
