Converting a manned LCU into an unmanned surface vehicle (USV): an open systems architecture (OSA) case study

Abstract

This thesis demonstrates the process by which the concepts of open systems architecture (OSA) might be applied within the context of an existing systems engineering methodology to result in a flexible system. This is accomplished by combining an existing systems engineering process model with OSA management and business principles to execute a successful asset-repurposing program. To demonstrate utility of this OSA approach to systems engineering management, this thesis analyzes an atypical asset-repurposing program: the conversion of a 1610 Class Landing Craft Utility to an unmanned surface vehicle. This thesis shows that OSA technical architecture is best implemented by defining high-level, business and technical flexibility requirements. This thesis argues that proper up-front architecting can balance non-recurring acquisition costs with future recurring lifecycle and modernization costs. A reference model and open standards are used to show the value of interface flexibility. This analysis makes the case for extending the useful service life of a Naval asset via repurposing rather than disposing of the asset, as is traditional. Furthermore, this analysis shows that strategic reuse or repurposing of assets represents an innovative alternative to the traditional sense of new-product acquisition, new-construction, and product modernization decisions.
