“…77 hardware obsolescence timelines, or life-cycle cost reduction, among other things. Schank et al (2016) investigated MOSA's potential in shipbuilding, and Kim et al (2020) did the same for space systems. 81 Both analyses found much potential in MOSA, but its utility depends on the context and program details, the universality and adherence to the standards selected, the level at which modularity is specified, and investments in organizational changes and workforce training.…”

Improving Defense Acquisition: Insights from Three Decades of RAND Research

Improving the U.S. Department of Defense (DoD) acquisition system-the management and development processes by which the department acquires, develops, and sustains weapon systems, automated information systems, and services-has been an issue of sustained interest to policymakers since the beginning of the military establishment. Numerous actions have been initiated and implemented over decades to rein in the increasing life-cycle costs and to ensure a timely delivery of these systems to meet U.S. security needs. In 1986, a confluence of trends external and internal to the department prompted Michael Rich, Edmund Dews, and C. L. Batten, Jr., to write Improving the Military Acquisition Process: Lessons from Rand Research. In that report, the authors identified major trends expected to affect the acquisition of defense systems for DoD and drew on RAND Corporation research to develop a strategy for meeting the challenges imposed by these trends. Like that earlier work, this report is informed by opensource documents and draws on insights from publicly available RAND research to suggest potential improvements that might help address challenges in the defense acquisition process. The issues that we highlight are also informed by other organizations examining defense acquisition issues.We expect this document to be of interest to DoD policymakers, congressional lawmakers and their staffs, and anyone interested in the acquisition of defense systems.

“…Nevertheless, modular design can be applied also to the design and retrofit of civilian vessels in order to ease a good balance of a wider range of design conditions and constraints [3]. The modular design is based on two key elements: modularity and flexibility [6]. Modularity consists of design functionally partitioned blocks, containing all the means for their connection with other blocks.…”

Nowadays specific ships are used to train students as sailors. As historical vessels are conveniently employed to this aim, the average age of these ships is usually high. In order to amortize operating and maintenance costs, the training ships' ownership (except for naval ones) is shared among multiple entities and schools. Moreover, generally these vessels are used in coastal navigation. The consequent operational profile imposes the need to rearrange the ship internal spaces according to the shipowner who will use it. Considering all these reasons, a modular design approach can be adopted in the refitting process, while reverse engineering techniques and integrated design tools should be used for the reconstruction when the original technical documentation is not available. In this context, hybrid-electric propulsion systems can be proposed as effective to enable the Zero Emission Mode, thus reducing the vessel's environmental impact during the training. By doing this, three goals are achieved to extend the ship operational life: ease of rearrangement of the internal spaces for different uses, reduction of operating/maintenance costs and eco-sustainability in coastal navigation. In this paper, after a description about modular design and hybrid electric technologies, the refitting project of the M/N "Umberto d'Ancona" is discussed. The latter is the training ship of "Tomaso di Savoia Duke of Genoa", the nautical institute in Trieste, Italy.

“…Realizing these objectives demands moving away from tightly integrated systems and towards modularity where ships can be built more quickly, more cost-effectively, and with inherent interoperability capabilities to maximize open architectures and extend ship lifecycles via rapid systems upgrades ( Figure 2). Maintaining maritime dominance in the 21 st century will require decoupling modular systems from platforms so that parts of the ship that change more rapidly can be modernized quickly without causing problems with the parts of the ship that change more slowly (Schank, 2016;Greenert, 2012). This evolution will necessitate fundamental changes to how ships are designed, constructed, maintained, and modernized (Spero, 1971;Gates, 1985).…”

SynopsisPower and energy have become a strategic and operational imperative for both the Royal Navy and United States Navy. The 21st century pace of change is unparalleled, with threats evolving at increased range, complexity, and sophistication. State and non-state adversaries are gaining technological advances and expanding their ability to conduct combined operations. Rapid fielding and seamless integration of advanced power and energy capabilities, such as power continuity across systems and electrically-powered weapons and sensors, will be critical for allies and partners to keep pace. As energy is one of the primary drivers for enhanced warfighting capability, these capabilities will be spurred by advances in power, energy and integrated system level controls. Further, the evolution of asymmetric threats will require disruptive and technologically superior solutions that create resilient networks and operate in a fully distributed manner.
