Home : Home : PEO IWS : About PEO IWS


PEO IWS provides the program management and system engineering expertise spanning across the Acquisition Life Cycle of the services, solutions, and products we provide to the Fleet to meet warfighter requirements across the Space, Air, Land, Surface/Subsurface and Cyber domains.

Our engineering and acquisition experts partner closely with Industry, Academia, Service Laboratories and Field Activities to produce reliable and effective combat systems to meet current and emerging threats. PEO IWS leads the open architecture initiative and develops systems for the Navy, other military services and our allies.

With an enterprise-wide focus, PEO IWS manages and coordinates the design, procurement, and lifetime support 
of integrated combat systems. Our systems include missiles, radars, launchers, electronic warfare systems, undersea warfare systems, gun systems, and combat systems.

Achieving the Navy’s goal of acquiring and maintaining the Battle Force is a challenging task requiring the finest and 
best trained workforce. PEO IWS accepts that challenge and works as a team to ensure that our Navy’s needs 
are met by acquiring the best and most cost-effective integrated weapons systems for our ships, submarines, and aircraft, both today for our in-service and for our future new construction ships.


Fleet Focused — Provide safe, effective, technologically superior and usable combat systems.

Drive Affordability — Identify efficiencies, target affordability, control cost growth and shorten cycle-time for the delivery of capabilities.

Apply System Rigor — Apply system Engineering Leadership and principles that will enforce traceability from requirement definition to fleet support.

Develop our Workforce — Prepare the organization for future success by providing mentoring, training and career management for IWS with ethics as our foundation.
