• A “system of systems”: Operate in battle force with older and newer ships • Very low quantities, high unit cost, long lives • Extremely complex product: millions of piece parts • No prototypes, first ship(s) must be fully operational • Government develops combat/weapons/communications systems • Government ultimately assumes responsibility for meeting requirements • Lack of commercial shipbuilding industrial base to build upon • Intense Congressional oversight
Nature of the Product – A Warship

RF Integration Challenges
Numerous antennas competing for limited space and coverage result in a complex electromagnetic environment (EME), presenting a challenge for effective topside integration and maintaining the topside baseline.

LPD 17
• First amphibious ship designed to specific survivability and vulnerability requirements:
• greatly reduced signatures, • hardened structure, • improved separation/redundancy, • significantly enhanced self defense systems, and • cooperative engagement capability.
• First surface ship designed for a 40-year service-life
