Naval studies show thatships are seldom lost to primary damage (direct blast effects) but the result of secondary damage: the progressive spreading of fire and flooding into surrounding areas
Key Challenge is to Increase Control System Survivability & Decrease Casualty Response Time
Past experience has demonstrated that when engineering casualties or damage occurs a human is too slow and vulnerable, and requires enormous logistical and medical support
Distributed, Survivable Autonomic Processing Contributes to Reduced Response Time

Defining the Requirements for Survivable Computing
Smart Valves sense or infer valve and fluid parameters
valve (actuator) position
fluid flow rate
upstream and downstream fluid pressure
Embedded, programmable microprocessor-based controller
controls valve actuator
filters sensor data
estimates flow rate
perform valve actuator diagnostics
can be programmed to be “intelligent”
interface with device- or field-level network
send/receive information to/from other devices on the network
send/receive information and commands to/from next highest control system tier

Naval Surface Warfare Center (NSWC) in Philadelphia to accomplish Ship Alteration 480D for the following ships: USS Boone, USS McInerny (FFG 8), USS Gary (FFG 51), and USS Vandergrift (FFG 48).
To regulate the cooling of the four SSDGs, as well as the SSDG waste heat temperature,
the fuel temperature in two sets of oil service and transfer heaters, the hot water tank temperature, and the start-air-mixer air temperature.
The PACs also control the main engine lube oil purifier, cooler, and service pressure loops.

New Shp Classes will be able to employ Decentralized Ship System Architectures with Distribute Control Systems in order to Improve Rapid System Recovery / Ship Survivability and Fight Through Capability
Survivability is Achieved through Computational and Process Electronics Protection Provided by Hardware, Hardware Architectures / Control Software that is Mil-Spec and Locally Reconfigurable
Using Control Hardware that has been Tested to Highest Level of Survivability to Reduce Vulnerability to Damage and Ensure No Critical Single Points of Vital System Failure
This solution Supports Reduced Crew Size, Lowers the Weight of Wire, and the Cost to Install Control Systems thus Improving Ship Production.
Proposed solutions are Technical Readiness Levels 7, 8 & 9.
