The Dstl Maritime Autonomous Platform Exploitation (MAPLE) project has played a leading role in shaping Royal Navy thinking about the integration of MAS into at sea platforms and in support of forces ashore. This paper touches briefly on the MAPLE context and the work being done to translate MAPLE research and development into an initial fielded solution under the Naval Strike Network programme, but the principle focus is on the next phase of the Dstl MAPLE 5 programme as it explores the challenges of exploiting a rapidly advancing technology base, looking beyond near term deployments and meeting MOD direction to unlock the potential of the generation-after-next. The paper explores: the integration of increasingly autonomous effectors and swarming systems and the need to consider MAS as force assets, operating across multi-national task groups and supporting new deployment patterns such as airborne crewed uncrewed teaming. As part of the ongoing MAPLE programme, the paper also will cover how international experimentation is moving beyond low level information integration to achieve a higher level interface, including recent work in Australian as part of Autonomous Warrior 22, as well as making extensive use of synthetic trials and federated facilities.
