(ITAR) controlled BYG-1 software, or the sensitive
intellectual property provided by product suppliers.
Our 500-strong combat system integration
workforce executes this work here in Australia, from
our facilities in Henderson, Adelaide and Sydney.
There have been some comments that because
the combat system was designed for a U.S .
nuclear submarine it is quite power hungry and
that impacts on the submarine’s indiscretion
rate. Is this the case?
Factors such as space, weight and power are
critical to all submarines; there are recent examples
of international diesel submarine design projects that
have suffered due to not getting this right.
Comments on the ‘combat system designed for US
Nuclear Submarines’ may refer to the AN/BYG-1. It
is worth noting that BYG-1 performs the ‘tactical and
weapons control’ function, and forms only a small part
of the overall ‘combat system.’ The rest of the combat
system includes the acoustic systems, navigation
systems, communications and other equipment; many
of these systems on Collins are not US sourced.
The RAN / DoD talk about the CS supplier
needing to work closely with the submarine
designer. What does this mean in reality?
The selected international partner for the design
and build of the Future Submarine will bring their
design skills and experience to the program. In other
similar overseas programs, each CEP candidate has
independently delivered entire submarines complete
with a combat system; however this will not be the
case in Australia.
For Australia’s Future Submarine, core elements of
the combat system including weapons, tactical control
and weapons control systems are co-developed with
the United States Navy (USN). Many other combat
system requirements are Australian unique and highly
classified. As a result, the designer is unlikely to attain
data access to complete the submarine. Therefore
the Combat System will need to be managed by an
Australian CSI who will work closely with the designer
to deliver a whole of submarine capability to the RAN.
For how long has Lockheed Martin (and its
antecedents) been producing submarine
combat systems? Please provide a few brief
Lockheed Martin pioneered systems integration
more than 40 years ago. Today we design, develop and
integrate submarine combat systems and subsystems
for navies around the world, including the US, UK,
Canada, Brazil and Spain.
We are the US Navy’s submarine combat system
integrator. This work spans 72 submarines and
includes submarines currently under construction and
combat system modernisation across the entire fleet.
LM is the only CSI with the expertise to achieve
concurrent design, development and production of
new submarine and combat system developments.
This expertise come from our role on the Virginia Class.
On which class or classes of submarine are
Lockheed Martin combat systems currently
A submarine combat system is comprised of several
functional elements with many subsystems in each
functional element. The submarine combat system
functional elements include:
• Tactical and Weapon Control
• Imaging (Optronics)
• ESM or Electronic Warfare
• External Communications
Although LM provides several submarine combat
system functional products, its major role is as the
Combat System Integrator (CSI) for all US Navy
submarines. In this role the CSI ensures that the best-
of-breed products and subsystems are effectively
integrated into a high-performing combat system.
LM provides sonar system with the designator AN/
BQQ10. This system is commonly referred to as
Acoustic Rapid COTS Insertion (ARCI) COTS-based
open architecture and is the US Navy’s submarine fleet-
wide sonar fit. LM also develops an EW system with
the designator AN/BLQ-10, inboard visual processing
with the designator AN/BVS-1, OE-538 multifunction
communications mast and combat system workstations.
The USN submarine classes and numbers of submarines
fitted with these subsystems are:
• Los Angeles (SSN-688) 39 submarines
• Ohio (SSGN) 4 submarines
• Ohio (SSBN) 14 submarines
• Seawolf (SSN-21) 3 submarines
• Virginia Class 10 submarines with a total of 30
The US submarine standard fleet-wide fit for Tactical
and Weapon Control system is known as AN/BYG-1.
This is a USN product, and the RAN is part of a
joint development program for the spiral development
process to maintain currency of the AN/BYG-1 Tactical
and Weapon Control system. Lockheed Martin is
responsible for design of the AN/BYG-1 processing
and as the USN’s combat system integrator we are
also responsible for the integration of AN/BYG-1 into
the combat system. Lockheed Martin also produces
the USN’s MK48 Heavy weight torpedo functional
items. LM has developed and supplied the Tactical
and Weapon control systems for the MK48 torpedo to
Canada, Netherlands, and Brazil.
In addition to LM’s current USN submarine activities
and responsibilities, Lockheed Martin have developed
products and provided combat systems integration
services and solutions for the following International
a Australian Collins class submarines – LM Buoyant
Wire Antenna as a legacy subsystem fit and the LM
OE-538 Multi-function external communications
antenna as a capability enhancement being
progressively fitted during maintenance availabilities.

c Tikuna class (TKMS Type 209) – Brazil Submarine
Modernization - Installation of Mk 48 Weapon
Control System, new sonar systems, processing,
d Victoria Class Canadian submarine upgrades
providing fire control/weapon control and a sonar
system as a variant of the ARCI.
e Netherlands Walrus Class – New Mk 48 HWT

f Spanish S-80 class submarine – SUBICS (sonar
and components of the Combat Management
To support their case for the role of Future Submarine
CSI, in November Lockheed Martin opened an
Adelaide-based research centre, with the involvement
of Thales and Saab. The company says this laboratory
includes a reconfigurable submarine command
centre to test and validate the Royal Australian Navy’s
concept of operations in a simulated operational
environment. The laboratory will feature advanced
computer processing with reconfigurable hardware,
and collaboration space dedicated to bringing known
and proven technologies to the next generation of
It is still early days in the project and once a combat
system integrator has been selected, lines of
responsibility will need to become better defined to
avoid some of the early problems of the Collins fleet.
In making the announcement about the designer, the
Prime Minister said the DCNS “Barracuda” had been
selected for a number of reasons, including “superior
sensor performance” and stealth characteristics. If
the Government is already making selections about
sensors even before the choice between Raytheon
and Lockheed Martin has been made, the eventual
outcome could be messy. However, we have a decade
and a half to get it right.
