2 Agenda Introduction to “Flexibility” Foreign Navy Flexible Warships: Germany, Denmark, United Kingdom, The Netherlands, Italy and FranceSummary of Flexibility Enablers on Foreign WarshipsPositive Impacts of Flexibility Enablers on Foreign WarshipsFlexibility Enablers Applied Over the Life CycleUS Flexible Warships:History,Applications for the US Navy - Future Flexible WarshipsObservations & AnalysisRecommendationsWe wanted to take a look at what’s happening with “Flexibility” in the foreign navies of some of our NATO allies and how can this apply to the US Navy.Our Introduction to Flexibility will define how we characterized the ship programs we reviewed.We will review flexibility for early innovators (Germany and Denmark) and follow with developments in the Netherlands, the United Kingdom , Italy and France. Discuss impacts and look at how these relate to a ships life cycle.Finally we will present a brief overview of the history of Flexible warships in the US Navy and provide some analysis and recommendations for Future Flexible Warships.
3 Flexibility Definition Flexibility is defined as:“The ability of a ship to adapt to universal or alternate solutions with the benefit of increased capability, reduced cost or both.”Flexibility can have multiple definitions. We wanted to use a definition that would provide a more comprehensive view of foreign naval ship programs.[Read the definition]
4 Key Attributes of Flexibility NAVSEA Flexible Ships Roadmap 2014 DescriptionAdaptabilityShips built with the ability to accept systems/equipment that can be removed and replaced according to specified time/cost objectives to adapt a ship’s capabilities to a given mission.ModularityShips built with standardized interfaces and modular components that reduce the complexity of producing/integrating systems and modernizing capabilities.ScalabilityThe ability of hardware/software combinations to be increased/decreased to match capability requirements of different sized ship platforms without sacrificing performance.Payload CommonalityPayload systems developed independently of ship platforms using standardized design specifications allowing the same systems to be applied across multiple platforms.The Flexible Ships Roadmap was completed in May 2014 by PEO Ships to identify opportunities to insert flexible technologies and characteristics in Navy surface ship and mission systems programs over the next several decades. This Roadmap identified the four key attributes that define flexible ships: Adaptability, Modularity, Scalability and Payload Commonality. We wanted to ensure that our analysis of foreign flexible warships would align with this roadmap.
5 Flexibility Enablers (1 of 2) Production Modularity – The use of production processes that use standardized design elements as the building blocks to produce customized ships. This includes the use of modularized equipment to facilitate streamlining of outfitting and furnishing.SWAP-C – Growth Margins for Size, Weight, Power and Cooling.Flexible Design Provisions – The incorporation of considerations that support technology insertion or mission reconfiguration at reduced cost. This includes design benefits that aren’t included in other categories (e.g. access routes).Modular Payloads/Stations – Modular Stations - ship spaces that are designed with standard module interfaces. Modular Payloads are the packaging of equipment or systems that can easily be integrated into a ship space or module station.During the assessment of foreign warship programs, we looked at what “flexibility enablers” are present in these ships that meet the our definition of “flexibility”. All of these enables can be found on at least one ship program.
6 Flexibility Enablers (2 of 2) Flexible Mission Spaces (Mission Bay) - Ship spaces that support reconfiguration for multiple missions using multiple module stations.Open Infrastructure – The built-in ability of a ship platform to easily accommodate change. This includes the use of a common computing, data, communications infrastructure.Open Standards – The use of requirements that are not customized for a ship or a payload module.Commonality - The use of items that are shared with other subsystems or naval platforms.

The following enablers could not be directly mapped but are included since they meet our definition of “flexibility” and they can provide significant cost reduction benefits.

19 Observations and Analysis What can we learn from foreign flexible warships?- Foreign Navies made decisions in favor of building flexible warships for near term savings. These include:Improved construction process and MEKO demonstrated savings in in construction time, labor hours and ship construction costs.Mission Reconfiguration Capability in a Single Hull (The Danish Navy was able to replace 20 Patrol Boats with 16 Patrol Boats that could be tailored to the mission.)Use of a common hull (platform) for multi-national use (The FREMM project supports both Italian and French navies, sharing shares common systems and NRE costs.Flexibility benefits are proven and are driving decisions for wider adoption by these navies.Blohm + Voss demonstrated 25% savings in construction time, 40% savings in labor hours, 17% savings in ship construction costs including combat systems installation
20 Recommendations for Future U.S. Warship Development Top Priorities for Implementation of Flexibility:Shipyards for the next Surface Combatant should use modular payloads for streamlining the construction process.Cost estimators need to develop a process based cost model that will more accurately calculate construction costs of flexible warships.Equipment suppliers need to learn “what’s in it for them” by documenting the benefits already obtained by equipment suppliers to the various foreign flexible warships.The U.S. Navy needs to realize that building a “common hull (platform)” with flexibility enablers is low risk because it has already been done. By building flexible surface combatants that can affordably/quickly modify or upgrade its payload, the Navy will save money, improve each ship’s AO, and therefore provide more “bang for the buck” to rest of the fleet.The concept of a Flexible Warship can help the Navy achieve both cost and capability goals for its ships. It is hoped that the information presented in this paper will assist in the efforts to develop a true “Flexible Warship” for future Navy surface combatants.1. Shipyards need to understand how to optimize construction processes to take advantage of decoupled modular payloads.
