    Abstract: ALMA (Acoustic Laboratory for Marine Applications) is a deployable and autonomous acoustic system, with passive and active sub-systems, designed in 2012 by DGA Naval Systems. The objective of the ALMA project is to anticipate and explore new scientific and technical topics for Naval Programs in Underwater Warfare, in order to contribute to the risk reduction on new technical challenges and to improve the mastering of sonar performance in highly variable and fluctuating environments (especially in coastal waters or shallow waters).\nThe main scientific and technical objective of the ALMA project is to increase the scientific knowledge of the impact of the environment and of its variability at different temporal and spatial scales, on the acoustic propagation and on the signal processing in the sonar domain. \nRelated to this objective the ALMA approach is to mobilize and to federate the academic and industrial communities on new issues and challenges in Underwater Acoustics by : (1) collecting high quality and unclassified real data (acoustic and environmental data) which may be shared with the scientific community, and by (2) conducting actions with the S&T DGA support tools (Defence and Dual research programs).\nIn this paper, the authors present a brief progress report on the ALMA project since the first at-sea deployment of the first version of the system in 2014. This five-year progress report is presented in three axes of complementary actions : (1) the scientific program and the related scientific projects(2) the five at-sea campaigns (one per year) and the associated acoustic and environmental data collected, and (3) the successive evolutions and improvements of the ALMA system, related to the scientific projects.\n
