When Australia (sometime between 2016-2020?) chooses a combat system for the Future Submarine many considerations and possibilities are open. A combat system is a system of sensors (SONAR, electronic warfare, air-surface detection, navigation systems, communications) databases, for decision making, close-in steering and targeting. The combat system interacts with all of a submarine's weapons.

If there is a tender for the combat system many companies and combinations of companies may put forward bids-solutions. My guess is that after some bidders are eliminated the two final bidders will be:

- the ATLAS ELEKTRONIK ISUS 90 (or the more advanced ISUS 2000) with ATLAS is owned by ThyssenKrupp and Airbus DSThyssenKrupp owns Howaldtswerke Deutsche Werft (HDW) the world's largest conventional submarine builder. The prospect of the one major company, ThyssenKrupp, through HDW and Atlas offering the submarine and combat system (respectively) to Australia makes sense. ISUS means Integrated Sensor Underwater System

ATLAS ELEKTRONIK's ISUS 90 sales statement http://www.atlas-elektronik.com/what-we-do/submarine-systems/isus90-combat-system/ includes:

"ATLAS ELEKTRONIK is the undisputed technology and world market leader in command and weapon control systems for non-nuclear submarines. Our “Integrated Sensor Underwater System” (ISUS) is based on many years of experience, is tried and tested, is always at the latest technological level and, thanks to its modular structure and open system architecture, can easily be adapted to suit individual customer requirements and diverse operational scenarios. It enables the submarine crew to fully perceive their surroundings and to analyse the situation in detail, permitting a rapid and reliable response...The quality, reliability and performance of this system is unparalleled worldwide. And this technology lead is highly valued by our clients: ISUS is well-established at more than ten navies around the globe; our sonar systems are in service with over two dozen navies."

The ISUS 90 is on many of HDW's all export Type 209 and 214 submarines

- SUBTICS or Submarine Tactical Integrated Combat System, offered by DCNS. System developed by Thales Underwater Systems-naval submarine division (Thales owns 25% of DCNS) and UDS Internatonal (all very complex and mixed up French corporate and government share holding-ownership - beyond comprehension). SUBTICS varies according to performances and integration level, in utilising sensors and weapons. It is used on all French Navy SSNs and SSBNs and has been chosen to equip next SSN generation Barracuda. 

On export markets, it is selected to equip every new submarines of Agosta, Scorpene and Andrasta types and to modernize submarines such as the Type 209. 


  • Submarines are increasingly faced with various missions including littoral and blue-water operations, stand-alone missions or within a naval force. SUBTICS indicates it can offer:
  • Efficient acoustic sensors including low frequency arrays and scalable data processing offering outstanding detection abilities of distant targets at high speed; 
  • Efficient non acoustic sensors on the surface and at periscope depth offering a high level of discretion; 
  • Communication facilities (from VLF to SHF), noiseless and fully integrated allowing submarine to interact in real time within a force;
  • Data synthesis from every sensors (optical, optronic, R-ESM and C-ESM, radar);
  • Advanced, automatic and interactive target motion analysis Tracks identification and classification functionality;
  • Track fusion and association through an interactive track management tool; 
  • Tactical, command and engagement aids with regard to geographical and tactical environment 
  • Tactical Data Links operation; and
  • Fire and weapon control Torpedoes : F17, SUT 266, TP617, Black Shark, F21 Missiles : SM39 and land-attack capability
SUBTICS provides systems for more than "40" vessels from 9 different Navies (including France).
  • Brazil (4 Scorpene being built) 1 SSN (to be built)
  • Chile (2 Scorpene, 2 Type 209)
  • Ecuador (2 Type 209)
  • India, (in the 4 Type 209 “Shishumar” class?)
  • Malaysia (2 Scorpene)
  • Pakistan (Agosta 90B, Khalid Classes),
  • Singapore (4 Challenger, 2 Archer Class) Type 218SG will not be using the French SUBTICS - instead using an Atlas Elektronik and ST Electronics designed system.
  • Venezuela (2 unserviceable Type 209)
- the GENERAL DYNAMICS AN/BYG-1 Tactical Control System (TCS). As well as General Dynamics Raytheon is a systems integrator for AN/BYG-1 - making the AN/BYG-1 even more of a multi-corporate responsibility proposition than SUBTICS.  

Australia is very accustomed to the AN/BYG-1 and TKMS has experience in integrating the AN/BYG-1 with Brazil's Type 209 submarines. Therefore HDW should have no problem integrating AN/BYG-1 into the 216-218 solution for Australia's future submarine. 

US and Australian military communications links are intense and complex. Many acronyms and levels might describe them. A  US maintained, immensely complex SeaWeb communications and sensor system might be one. Other "inhouse" acronyms might be used, like FORCEnet, which may mean the same thing. In the NATO context Link 22 (see large pdf document) may indicate the complexity of links for sea, land, and air communications-sensor network between the US and its North Atlantic allies - with Australia of course being geographically separated from it. Australia and the US would most probably have submarine communications-sensor links under the AUSCANNZUKUS naval Command, Control, Communications and Computers (C4) interoperability structure.

The US and Australia are constantly refining the US designed submarine combat system known as the US General Dynamics AN/BYG-1The AN/BYG-1 is apparently used on all US SSNs (Seawolf Class with AN/BYG-2 upgrade) and SSGNs as well as SSKs from:

Spain (S-80)
Brazil (Tupi Class (Type 209))
Canada (Victoria Class)

The Collins weapons include the American made Mk 48 torpedoes and Harpoon missiles. The Collins is (US Tomahawk SLCM capable. The mines are UK made.

SOURCES POINTING AT PREFERENCE FOR US

It is widely believed that (around 2000?) the Defence Materiel Organisation (DMO) and Submarine Capability Team recommended the RAN acquire the ISUS 90 system. However the Australian Cabinet favoured US systems.

See  http://gentleseas.blogspot.com.au/2013/05/a-new-australian-submarine-with-aip.html In October 2009 Australia's then Minister of Defence Material Greg Combet, speaking still current RAN views, indicated  that the US would play a big part in developing Australia's future submarine. The Sydney Morning Herald recorded what Mr Combet said on October 6, 2009. http://news.smh.com.au/breaking-news-national/us-to-play-key-role-in-new-aussie-subs-20091006-gky2.html: "US 'to play key role' in new Aussie subs" October 6, 2009...
"Australia wants the assistance of the United States as it looks to replace the Collins class submarines, junior defence minister Greg Combet says.
"...I expect that Australia will look to learn from companies like General Dynamics Electric Boat and Lockheed Martin in designing and developing the Collins class replacement," he said in a statement.
"...US technology is likely to be an important facilitator of this capability," he said.

See http://gentleseas.blogspot.com.au/2012/06/australias-future-submarine-selection-s.html of 20 January 2014 Prime Minister, Minister for Defence and Minister for Defence Materiel – Joint Media Release – 2013 Defence White Paper: The Future Submarine Program 3 May 2013 http://www.minister.defence.gov.au/2013/05/03/prime-minister-minister-for-defence-and-minister-for-defence-materiel-joint-media-release-2013-defence-white-paper-the-future-submarine-program-2/
"...The Government has also taken the important decision to use the United States AN/BYG-1 combat system as the reference system for future design work.  The early definition of a combat system is a feature of a successful submarine program.  It allows the submarine design to proceed utilising more accurate projections of space, weight and power requirements."

Also see  SEA 1439 PHASE 4A - COLLINS CLASS REPLACEMENT COMBAT SYSTEM http://www.defence.gov.au/dmo/msd/sea1439/index.cfm concerning an upgrade process of the AN/BYG-1 combat system conducted jointly by the US and Australia up to 2019 “in conjunction with the Replacement [amounting to upgrades of the US Mk 48] Heavyweight Torpedo (Project SEA 1429)” which points to future integration with US weapons.

- Some 2011 US RAND Corporation studies http://www.rand.org/topics/submarines.html concerning Australian submarine issues needs to be added.

An excellent source on Combat Systems generally and by system-maker is Norman Friedman The Naval Institute Guide to World Naval Weapon Systems 5th edn, 2006, pp. 133-156, text online

CONCLUSION


It is difficult to pick a winner. Australia should avoid solutions that: are divided, involve too many corporate-national vendors, as they lead to greater cost and program complexity. Therefore at least three options remain, including:

-  The prospect of the one major company, ThyssenKrupp, through HDW and Atlas offering the submarine (HDW 216 or 218) and combat system (ISUS 90 or ISUS 2000). This unity under TKMS is attractive.

-  If Australia chooses an enlarged Scorpene (with an eventual SSN a la Brazil possible) then SUBTICS would be a logical choice.

-  Australia is very accustomed to the US AN/BYG-1 (with an eventual purchase of US SSNs possible?) and several conventional submarine companies have  experience in integrating the AN/BYG-1 with conventional submarines. Also the US is Australia's most important ally.
