PROGRAM: SEA073, Advanced Submarine Systems Development
Develop a low size, weight, and power communication link that will operate
across the pressure hull of a submarine.
Hull penetrations on a submarine are always of concern as potential paths for
seawater ingress, and any new system requiring additional hull penetrations is
unlikely to be developed or adopted unless it supplants an existing system that
is deemed less important under some particular circumstance. A readily
available method of creating a non-penetrating communication link through the
hull will support novel sensor development and adoption with fewer concerns and
associated costs. A threshold capacity of 1000 bits/sec would have utility, but
two order of magnitude better data rates are desired. Possible modalities
include Electromagnetic and Acoustic.
I: Develop initial concept design and perform an analysis of the expected
performance of the communication system including the details of the
communication modality, modulation, and expected performance envelope to
include available bandwidth and bits per joule efficiency. Conduct an analysis
supported by component level testing. Include in the design: plans for form
factor, adhesion to the hull, and the power and energy strategy. Develop a
Phase II plan.
II: Develop a prototype through-the-hull communication system. Demonstrate
capacity and other performance metrics using actual transmissions of data.
Perform an analysis that includes efficiency as function of bandwidth and
expected endurance as function of duty cycle. Develop a production design,
including size, weight, power, and costs estimates, as well as complete system
performance predictions and evaluations to include capacity estimates under a
variety of environmental conditions and ranges. SECRET clearance may be
required for Phase II.
III DUAL USE APPLICATIONS: Install and test a functioning through-the-hull
communication system on an operational submarine to include sending relevant
information through the hull that would not otherwise be immediately available.
Determine the capabilities and limitations, and obtain end user feedback that
can be used to improve the system under a spiral development strategy. A dual
use application of the technology could be in the oil and gas pipeline
