BIW participates in S&T efforts BIW recognizes that early S&T participation

Enables lower implementation costs of systems BIW focus to develop fully compliant and cost-competitive proposals for

subsequent construction award

BIW historically responsive to Navys needs and acquisition approach

Evolving S&T strategy for surface combatants is not clear today

How S&T drives the enterprise

Past BIW Support of R&D and Transition of

Technology to Construction R&D

ONR High Speed Sea Lift (HSSL), High

Speed Connectors, High Capacityat-Sea Sustainment of Seabase(HICASS)

Missile Defense Agency studies Other Studies

LCS ISP, CG(X), JHSV, Fast

Response Cutter (FRC), SeaBasing, Maritime Pre-PositioningForce (Futures)

Transition of Technology to Construction

BIW production personnel providesupport and fab/construction of EDMsand prototypes.

Weapons Effects testing, FireSuppression (AFSS), Structural Units,

etc.

S&T Environment from 1996~2003 has shaped BIWresource planning

Section 845 approach rewarded industry investment

Full Service Contractor (design, construction, and life cycle support)incentive to provide ship life-time support

BIW DD-21 acquisition approach enabled long-term technical

staffing plans Created structure to assess and pursue technologies Built up In-house engineering staff

Explored Non-traditional capabilities

Established partnering (MOUs) with Navy organizations Linked with Production for assistance and assessment of EDMs

Focused on Engineering employee development

System Engineering process

CAIV and Total Ownership Costs (TOC)


7/12

BIW Engineering has maintained Core staffingskills and levels

Unique skills developed in DD-21/DD(X) programshared across current Navy S&T tasks

Demonstrated capability through DDG-1000, LCS,

DDG Modernization, CG(X), FSC studies, etc Technical staff planned to transition construction and

life cycle support

Outlook for S&T shipyard staffing

Recommendations Establish win-win environment for collaboration of industry-Navy-

academia Review current skill drivers

Identify new and unique skills Assess core technical disciplines for relevance

More partnering in S&T activities to reduce costs, improveefficiencies between organizations

Backup

Specific Skill Sets needed to effect transition of S&Tinitiatives on recent navy programs.


11/12

Skill Set demands

Future S&T related Skill sets and capabilities neededcurrent and future shipbuilding programs:

Electrical Power Engineers: driven by new Navy requirements

(IPS), high power electronics, and distributed high voltage

Controls and Instrumentation Engineers: Numbers of signals andinterfaces have increased 10-fold since last combatant class, insupport of reduced manning.

Software Engineers: Shipyards are procuring equipment withsignificant SW content. Focus on process and integration

Advanced Structural Analysis Structural analysis is back to first

principals (ABS) and less rule governed. Also more use ofstructural dynamic models


12/12

Future Skill sets:

System Integration Naval Architecture, arrangements and shipdesign/build. Systems Engineering skills to assess life cycle,

producibility, and other total ownership costs HSI knowledge of processes for the full range of human

integration activities unique to ship operation, construction, taskanalysis, safety, and Human Factor skills required to integrate

and assess combatant design; Damage Control and CrewDesign
