Develop a capability for acoustic torpedo countermeasures to coordinate focused
layered defense strategies against incoming advanced threat torpedoes.
All submarines are currently protected by 6-inch and 3-inch diameter expendable
torpedo countermeasures that, upon launch, act autonomously and independently
to thwart adversarial weapons. Adversarial weapons are becoming more and more
sophisticated requiring the Fleet to develop smarter and more capable
countermeasure devices. It is the intention of this effort to develop
additional capabilities that can be incorporated into current and future
torpedo countermeasures to provide increased platform protection. As such, the
innovation sought by the execution of this effort is to develop the ability for
multiple acoustic countermeasures to coordinate a layered defense against
adversarial torpedoes. The countermeasures, which are based either on the
existing three-inch diameter Acoustic Device Countermeasure (ADC) Mk 2 Mod 7 and/or
the existing six-inch diameter ADC Mk 3 Mod 1, would have the ability to
identify the incoming direction of a threat torpedo through an onboard
receiver(s) or other devices/platforms in the engagement. Additionally, the
solution will use its relative positions to provide spatial, temporal, and
spectral defensive protection for the host platform. The ability to detect the
threat, identify threat localization, and implement appropriate threat acoustic
responses amongst a potentially highly cluttered acoustic environment will be
evaluated. The specific acoustic response would be based on the existing
acoustic modes of the current ADC, depending upon the chosen form factor for
the design. The innovation challenges involved in this topic execution are
twofold: first, coordination of the communication capabilities amongst multiple
torpedo countermeasures and with the host submarine platform need to be robust
in what is anticipated to be an acoustically cluttered environment; second,
technology advancements are needed to provide this coordinated capability
(on-board receiver and identify friend or foe (IFF) and communication logic)
without driving significant increase (less than 25%) in unit cost and not
significantly changing the form factor of the baseline device (either 6-inch
diameter, 100-inch long, 120 pounds or 3-inch diameter, 39.5-inch long, 10
pounds). By providing these additional features, these advanced countermeasures
will possess the ability to reduce the number of devices needed to thwart
adversarial threats with a reduced number of devices, thus offsetting the
anticipated increased unit cost per device. The Technical Point of Contact will
provide Testing and evaluation criteria on an as needed basis.
Develop an end-to-end design and implementation concept for a coordinated countermeasure
using acoustic or non-acoustic technologies, including (1) receiver
technologies and (2) on-board electronics that are powered by the same power
supplies currently in use by the legacy devices: either thermal lithium like
the ADC MK 2 MOD 7, or silver chloride seawater activated battery like the ADC
MK 3 MOD 1 ,to provide the capability to identify incoming threat torpedoes and
send the appropriate signals to the existing acoustic projector to thwart the
threat. Consider a device solution that is based on the existing legacy
devices: ADC MK 2 MOD 7, and/or ADC MK 3 MOD 1. Establish feasibility of the
proposed concept. Evaluate the operational ability of the device design will be
evaluated per the requirements in the Description. The Phase I Option, if
exercised, will include the initial system specifications and capabilities
description to build a prototype solution in Phase II.
Develop and build three to five prototype systems for testing and evaluation.
Conduct evaluation and testing of the prototypes based on the anticipated
inter-countermeasure and countermeasure from/to host platform communication
links, which are expected to be simplistic, yet robust, and have the ability to
avoid host-platform “beaconing.” Ensure that the specific acoustic response
would be based on the existing acoustic modes of the current ADC Mk 2 Mod 7
and/or ADC Mk 3 Mod 1, depending upon the chosen form factor for the design.
Evaluate the robustness of the communications technology. Subject the prototype
devices to limited environmental testing and design risk reduction evaluations.
Focus testing primarily on the evaluation of the communications implementation,
with environmental stress testing, as noted in the Description, folded in to
mitigate operational design risks. Develop a Phase III plan.
DUAL USE APPLICATIONS: Support the Navy in transitioning the technology for
Navy use. Deliver five to six follow-on prototypes (incorporating any lessons
learned from the Phase II prototyping and testing efforts) and engineering
support for full environmental testing. Conduct the following testing: storage
temperature thermal cycling (-54°C to +71°C) testing; shock testing
(MIL-S-901D), hydrostatic testing to submarine operational depths, internal
countermeasure launcher acceleration testing (via the Naval Undersea Warfare
Center Division Newport’s internal countermeasure launcher facility), and any
additional evaluation testing for the newly developed communications
technology, including, in-water acoustic testing in a demonstration on an
instrumented Navy test range. (Note: Some of this testing may occur in Phase II
if the Phase II prototype design is a mature representation of a potential
low-rate initial production design.) Depending on platform availability, it is
anticipated that some, or all, of the prototypes will be evaluated through
real-world range operations with active torpedoes or with a host submarine.
Ultimately, the primary focus within a Phase III effort will be on evaluating
the ability of the devices to coordinate collectively for effective host
platform protection, while showing resiliency against applicable environmental stressors.
