Chart of Japan's Soryu Submarine Combat System, and AN/BYG-1 Integration

This Soryu submarine Combat System flow chart (and a vast amount of information) is in  wispywood2344's website, passed on by S.  More below.

Submarines are very complex especially the way their display terminals, mainframe capacity databases, sensors, weapons and people interact. All these elements make up the combat system. 



This Australian Defence Force slide display (2015) of the Competitive Evaluation Process (CEP) has this longer definition of combat system (above).
---

The Australian Federal Government has invited both Raytheon and Lockheed Martin (facility in  Adelaide) to participate in the process for selection as the integrator for the combat system for  Australia’s future submarine. 

All eyes have been on the three way (Japan, Germany and France) submarine (CEP) contest but what may make or break the future submarine project also includes how efficiently the combat system is integrated. 

This invitation to integrate the combat system is restricted just to those two US companies because of the top secret nature of the US AN/BYG-1 combat system. The US AN/BYG-1 combat system (already in the Collins) is the only combat system considered and approved by the Australian Government for the future submarine. 

This approval was made public in a Ministerial Media Release on 20 February 2015 "the Government has endorsed a set of key strategic requirements for our future submarines:

a) Range and endurance similar to the Collins Class submarine;
b) Sensor performance and stealth characteristics that are superior to the Collins Class submarine; and
c) The combat system and heavyweight torpedo jointly developed between the United States and Australia as the preferred combat system and main armament."

Integrating the US AN/BYG-1 combat system may entail up to a third of the cost and effort to build the future submarine. Adding to the complexity and cost of this integration is that a third US company, General Dynamics is deeply involved in modernising/developing the AN/BYG-1.

If Japan is chosen in the CEP the US companies and Australian companies will need to work with Japanese companies to replace the Japanese combat system (below) or adapt parts of the Japanese combat which are already the same or similar to parts of the AN/BYG-1 combat system.



The Japanese Soryu submarine Combat System flow chart (above) is from wispywood2344's website passed on by S. This chart is much larger here which also contains a Comprehensive Reference List. This Soryu flow chart can be conceptually compared with the more detailed component chart (below) for the current US AN/BYG-1 combat system: 

Just some (eg. without the sonar sensor arrays) of the components of the US AN/BYG-1 combat system. See this image much larger and readable here.

Dear Pete,

the problem for Japan will be that it would be the first time they had to do it.

DNCS and ATLAS ELEKTRONIK are in this business for a long time. Atlas Elektronik is owned by ThyssenKrupp and Airbus DS (Defence Systems).

It is hard to get some information about the combat system except a few official ads:
https://www.atlas-elektronik.com/what-we-do/submarine-systems/isusr-100/
(Check the drop down menu "WHAT WE DO".)

The "System Architecture" looks differently to the US system.

The ISUS-system is used by over ten Navies and the sonar system by more than 2 dozen navies.

Hi MHalblaub

https://www.atlas-elektronik.com/what-we-do/submarine-systems/isusr-100/ makes it very clear about ATLAS ELEKTRONIK's combat and control “Integrated Sensor Underwater System” (ISUS®). Concept, Main Features, Capabilities and System Architecture are all included.

If TKMS-Germany won the CEP the AN/BYG-1 combat system could probably interface with many ISUS features.

Dear Pete,
The main feature of the ISUS concept is one common link for all systems. The input data from sonar, machinery data, LINK 16 or periscope video is provided to every other system like the terminals.

Also the results were streamed back.

A simple solution could be to use just one terminal as an interface to the US AN/BYG. The submarine would still be operated by its inherent system and just the user interface would be US/Australian made. The Mark 48 and Harpoon already work together with ISUS.

What ISUS offers is the integration of systems like Spider (torpedo hard kill) and IDAS missile for helicopter and other small targets. Btw. I am not aware of any successful MICA tests.

Dear S,
You may provide a link to the features a Japanese systems offers except the standard features.

Hi MHalblaub [28/1 9:32PM]

Yes utilising standard electronics already included in German, French or Japanese subs leaves appopriate room for the AN/BYG-1 to interface.

With all the focus being on the CEP (Germany, France and Japan) there has been minimal public or news discussion of the potential of US company combat system suppliers and integrators blowing out costs in the SEA 1000 future submarine project.

I'm concerned that the 3 US companies involved (Raytheon, General Dynamics and Lockheed Martin) will remove German, French and Japanese electonics where ever possible and profitable. The ensuing costs will be surprisingly high for the Australian taxpayer.

Dear Pete,

why does Israel not use a US combat system on their submarines?

Hi MHalblaub [30/1 12:23PM]

I'm not certain why Israel does not use a US combat system on their submarines. But reasons may include:

- TKMS/Germany requiring Israel to use the German Atlas ISUS combat system given Germany has given Israel around a 33% discount on upfront Dolphin prices.

- Israel in any case may have assessed the Atlas as more suiting Israeli needs than a US system.

- also the US may not trust Israel enough to allow Israel to use the AN/BYG-1 combat system. As revealed in the Samson Option Israel has some history of passing sensitive US intelligence to Russia.

- Israel also passed sensitive Western military technology to China a few years ago http://www.algemeiner.com/2013/12/22/u-s-furious-with-israel-after-sale-of-advanced-military-technology-to-china/#
