The aim of this study is to propose guidelines for the systems engineering of future stealth combat vehicles using Low Observable Technology (LOT). A case study approach, based on interviews and document reviews, was used to analyze the systems engineering processes of the SEP multirole armored vehicle and the Visby class corvette respectively. The result is a thorough investigation of what worked in the cases studied, butwith lessons extrapolated into recommendations for future development programs. These will have to deal with an increasingly complex sensor threat and a transformed, multilateral, European procurement environment. The main conclusion is that coherence and traceability between military needs on the battlefield and signature requirements is expected to be particularly challenging. A workflow tailored for requirements analysis in LO combat vehicle programs has, therefore, been derived and is presented here. In addition, themost important enablers for future multilateral development programs involving LOT have been identified as: establishing common best practices, demonstrator programs, an integrated product team approach, and, in line with similar work on combat aircraft, establishing stealth as a key architectural principle.
