ASW in the Asia-Pacific region

The Market Opportunities Presented by Rusty Kollmorgen, Strategy Director, Ultra Electronics, Sonar & Underwater Systems


Transoceanic trade MARITIME COMMONS FUELS THE GLOBAL ECONOMY1

•Maritime Commons: all unowned waters and the freedom to traverse per international law

•Since 1950, ocean trade has increased by 16x

•Over the same period, world GDP increased 8x

•Sea trade quadrupled between 1970-2011

•75% of 2011 world trade volume conveyed by sea

– Nearly 58% world trade value

Current and Future Energy Resources TRAVEL ON OR RESIDE BELOW MARITIME REGIONS1

•61% of the world’s petroleum pass through five choke points in contested waterways

– Luzon, South China Sea, Malacca, Maldives, Hormuz

•30% of global energy production comes from offshore sources

– 3,094 fields with: 7,779 platforms 602 mobile drilling units

Asia-Pacific’s Political-Economic Environment

•GDP grew 15% from 2008-2011 – expecting 18% growth to 2015*

•Increased attention to resource ownership

•Regional flashpoints – Historic tensions India/Pakistan – South China Sea – China / India

•Increased tensions as China flexes its regional influence more overtly


Asia Pacific Regional Tensions SPRATLY ISLANDS

•4 km2 land •over 425,000 km2 sea

•significant natural resources underwater


China’s Island Chains Maritime Defence Posture

•Provides wider influence over most critical maritime commons

•Blunts the current power projection capability of the US

•Confronts threats at distance

•This strategy is basis for commons “lawfare” tactics

•Creates unease in neighbouring nations


Increasing Defence Spend Follows Growing Tensions2

•28% growth 2008-2011

•38% increase projected through 2015

– Excluding China, up16%

•80 new submarines over 10 years in region

– 50 net inventory increase

Transformation of Airborne Sonar Presented by Alan Wignall OBE CEng MIET Technical Director, Ultra Electronics Sonar Systems 12th December 2012


Transformation of Airborne Sonar INTRODUCTION

•Background – Challenge – Approach – Players – Airborne multistatics

•Ultra’s airborne processing solution

– System architecture – Operator interface

• System management and control • Target detection and classification

•Concluding remarks


The Challenge SUBMARINE PROLIFERATION (*)

• Increasing build rate in countries of concern, e.g.:

– Russia continues to modernise – China (30 new submarines by 2020) – North Korea (SANG-O, YONO classes) – Iran (26: KILO, FATEH, BESAT & GHADIR)

•>500 submarines worldwide, increasing ~ 1 per month on average

•Shifting balance: more ‘concern’ than ‘friendly’

•How to achieve wide area surveillance and localisation of small quiet submarines?

(*) Analysis based on data from Janes Fighting Ships 2012-2013


The Approach •Recognise limitations of legacy ASW sonar:

– High power ship-centric sonar – Helicopter dipping sonar – Passive airborne sonar

•Exploit available technologies & systems: – Deployable sensors, from MPAs, Helos, UAVs, ships – Digital sensors and communications – COTS PC processing power – COTS mission system architectures – System & software development tools

•Build on Ultra’s existing products & skills: – Sonobuoy systems (buoys, telemetry, processing) – Integrated Sonar System (ISS) – Surface Ship Torpedo Defence (SSTD)

•The solution: – Distributed multistatic sonar – ‘Pervasive Sound’

Concluding Remarks •MSA will transform airborne sonar

– Quantum leap in sonobuoy system capability and complexity – Requires a new approach to processing, control and displays – Modern PC-based processing eliminates the need for bespoke hardware or boxes – It will lead to a new generation of optimised sonobuoys and deployable sensors

•Ultra is well positioned – The market is real – Ultra has a background track record in the technology – Our sonar system solutions are innovative and world class – We consider the whole problem, and provide a ‘sensor to display’ solution – We are well positioned to exploit the opportunities – We are engaged in the markets

•Ultra’s solution is innovative, and based on experience – Ultra’s airborne processing system is currently in development, based on ISS – Building on Ultra’s unique experience (15 years of MSA with Nimrod MR2) – Founded on over 50 years of sonobuoy system experience – The product is the processing not a processor – Geographically oriented, interactive, intuitive displays

•The approach extends to distributed sonar (in conjunction with other platforms)

Integration of Surface Ship Sonar INTRODUCTION

•Market background – Emerging navies require smaller, affordable ships – Every nation can afford to have one – The threat proliferates

•Solution to make smaller affordable ships – Smaller, cheaper, lighter systems

•Achieved through – Integrated systems - on-board, out-board, off-board – Integrated functions – surveillance, self-defence, countermeasures – Distributed sonar – future integration with other platforms & sensors

•Trend-setting contract – Ultra’s Integrated Sonar System for RAN Air Warfare Destroyer


Ultra’s Innovation in Sonar

• Pre UK SSTD, deployment of towed countermeasure arrays was difficult and often dangerous

• The rigid TB-14A, NIXIE, towed countermeasure which could not be reeled on a winch drum and required insertion into the towed assembly as it was being deployed

• Ultra developed the in-line flexible towed body to replace the TB-14A for the UK SSTD system, replacing an entire electronics cabinet


•Towed High Power Active Sonar – typically dual tow systems with separately handled rigid

body transmitters and acoustic receive arrays

– Ultra has replaced this with a single in-line towed system

• Developing capability for the Asia Pacific Market – The single in-line towed assembly requires only a single

handling winch – minimising shipfit impact and suitable for installation on smaller ships.

– The design of the ISS hull mounted array is flexible and is able to be reduced in sized and accommodated in smaller hull sizes

– Ultra’s innovative approach means the ISS is now suitable for smaller vessels – in addition to larger vessels

Towed Array Sonar FINDING THE TARGET FASTER

•Form an array with pairs of ‘co-located’ hydrophones •Use signal arrival time delay to resolve left-right ambiguity •Unable to cope with ‘roll’ of array during operation •Triplet of hydrophones is the minimum solution

QUAD Receive Array

•Ultra is unique in offering a QUAD (four hydrophone) solution.

•More accurate left-right bearing ambiguity resolution due to improved acoustic geometry.

•Increased capability to reject unwanted noise enabling higher operational tow speeds.

•Fourth hydrophone provides redundancy to triplet configuration allowing for graceful degradation.


Horizontal Projector Array

•Ultra is unique in the market space as the sole supplier of an HPA solution.

– one winch (less cost and complexity) – smaller and lighter than competing dual-tow

systems(can be used on wider range of warships) – Two transmission frequencies for simultaneous

ASW and torpedo defence modes

On-going Development

•Smaller array diameter, lower weight and less power – Further reduction in winch and handling system size and complexity – Reduces shipborne electrical requirements

•Increased ISS towed sonar performance – Higher Horizontal Projector Array energy output (source level) – Wider bandwidth (Passive and Active)

•Processing enhancements – Own ship’s noise rejection – Improved reverberation rejection – Improved ping strategies
