Building an Affordable Future Fleet
in an Evolving World
• Face uncertain times
– The threat is evolving
– Our technology is evolving
– Lean times ahead
• Ships and their systems
must be robust, flexible
and adaptable
– Shouldn’t optimize a point
design to a fixed set of
requirements
– HM&E Systems must
support changing
requirements

(Little Incentive)
A combination of strategies is likely optimal

Schelde Naval Shipbuilding: Sigma Design Concept
Can a qualified third party add, modify, replace, remove, or provide support for a
component of a system, based only on openly published and available technical
and functional specification of the component of that system?
Open Architecture
• Business practices
• Technical practices
– Open standards
– Published interfaces

Product Lines
• Specific requirements seldom
known when developing technology
• Traditional Approach – Anticipates specific requirements, but
usually “misses”
– Experiences difficulty matching S&T
completion and Acquisition: “R&D Valley
of Death”
• Product line Approach – Enables affordably and quickly providing
products meeting specific requirements
once those requirements are known
– Bridges the “R&D Valley of Death”

Product Line Approach
Product Lines enable manufacturers to quickly
and affordably respond to specific solicitations
with solutions that largely have already been
pre-engineered and de-risked.
Specifications and Standards
• Specifications
– List the requirements for buying an
item
• Standards
– Define interfaces, design criteria,
test methods, practices, and
manufacturing processes
• Key to open architectures and
product lines
– Developed in partnership with
industry
• Standard Ownership
– Industry standards
– Military standards

Reduced Acquisition Cost
• Update specifications and
standards
– Use commercial specifications
and standards where consistent
with naval environment.
– Modify existing or create new
military specifications and
standards to reduce cost impact
of successfully operating in a
naval environment.
• Update architectures
– Electrical Power Systems
– HVAC
– Machinery Control Systems
