The quickening pace of technological advancement will require submarine command teams of the future to process greater volumes of data, potentially with fewer operators. User Interfaces (UIs) have evolved to meet current requirements, but this iterative process has propagated legacy design paradigms that may be unsuitable for future system specifications.To understand where improvements may be made, a review of current submarine control room operation is presented, using a sociotechnical systems approach. The social (command team: work, structure, and communication) and technical (combat systems) components are presented for context. An emphasis is placed on Sonar and Target Motion Analysis due to their prevalence within the control room. It was found that current UIs place increased cognitive requirements on operators due to the complexity and quantity of information presented. It is proposed that adopting an Ecological Interface Design (EID) approach could reduce such issues, facilitating effective resource allocation to manage increased data volumes. EID has been demonstrated to be effective across many domains, however, its exploitation in submarine control rooms is limited. Advances in modern submarine combat systems have promoted greater flexibility, providing an opportunity to utilise contemporary design philosophies for designing intuitive interfaces to maintain effective control room performance.The submarine control room is a complex sociotechnical system, formed of a highly trained command team and advanced combat system, with the objective of successfully completing missions in challenging environments, such as littoral waters (Roberts, Stanton, and Fay 2018).The system has evolved over time and so are highly evolved regarding operational capabilities, but this does not preclude further improvement. Technological advancements are frequently implemented without formal assessment of their impact from a sociotechnical perspective (Roberts and Stanton 2018). On submarine platforms, technological advancements are affording greater capabilities to meet changing requirements of operation (Bateman, 2011, Dominguez, Long, Miller, & Wiggins, 2006. These include new sensors and upgrades to existing sensors, producing larger volumes of data (Stillion and Clark 2015) with a drive to reduce crew sizes (Ly, Huf, and Henley 2007;Masakowski 2000). A critical question is whether such advances are being implemented with adequate consideration of the capacities of the operators, who already process large volumes of information. Of interest for potential improvements are the User Interfaces (UIs), which despite being highly advanced, have design shortcomings that limit operator performance, and the capacity of the entire control room. It is proposed that these issues could be addressed by switching from an evolutionary design paradigm to EID. Such a paradigm shift could allow future control rooms to meet future challenges and maintain effective operation.
