        "description": "The Sonar Modelling Handbook (SMH) has been the standard reference for modelling, data and metrics across the UK defence underwater acoustic enterprise for multiple decades, supporting work within the MoD, industry and academia. It provides visibility to UK industry and academia of what the MoD considers the best information available and supports consistency in performance modelling across the UK enterprise. As Dstl embarks on a significant refresh of the SMH material and presentation for the digital era, including incorporation of the latest theory and data, and commissioning specific research, it is seeking to engage industry and academia across the UK to provide input as to the way ahead at a Preliminary Market Engagement Event (PMEE). This will include new mechanisms for refreshed limitations on dissemination.",
