COTS Subsystems for UUVs

securely store top secret data onboard
the UUV and then safely transport the
data on the RMC. The RMC is considered unclassified when removed and
unpowered.
Another challenge for UUV system integrators is integrating network communications capabilities within the platform. To address those requirements, as
well as provide encryption for data-onthe-move, there is a range of ultra-small
network switches and routers that support the popular and preferred Cisco IOS
enterprise networking infrastructure.
Currently in operation onboard a
Medium UUV platform are CurtissWright's DuraMAR network router solutions, and the PacStar 447 next generation network router will also soon
undergo testing in these types of platforms. These two product families provide UUV system integrators with a spectrum of ruggedization options, ranging
up to fully sealed enclosures, full MIL
standard environmental testing. They
support full military operating temperature ranges and, if required, standard
military connectors.
Parvus DuraMAR routers are COTS
mobile routers integrating a Cisco Systems Embedded Services Router (ESR)
card like the ESR 6300 or ESR 5915 in an
ultra-rugged chassis with circular MIL
connectors. They have extensive MILSTD-1275/704/810/461 qualification
testing and boast the cybersecurity afforded by Cisco's products. For applications that don't require the highest levels of ruggedization, the PacStar 447
small router module embeds the Cisco
ESR6300 card and provides high-performance routing, switching and advanced
network access in a compact, quick
setup, rugged form factor. PacStar 447
can be optionally managed by PacStar
IQ-Core Software, which simplifies system setup, network management and
protects the system from misconfiguration by operators in the field.
While a COTS vendor knows the
SWaP characteristics of its own solutions
onboard a UUV, they might not have
knowledge of what other customized or
other vendors' products must also be
hosted on the platform. For that reason,
COTS suppliers need to continue to
focus on optimizing SWaP as a matter of

course. By providing extremely compact, ruggedized, fully tested and standardized products, industry can best
support the system requirements for this
critically important new class of naval
platform and help to speed their development and deployment.
