A sonobuoy 10 comprises an upper unit 12 and a lower unit 14, arranged, in use, vertically below the upper unit, and a retention feature 54, in which the upper unit is realisably retained to the lower unit by the retention feature. Advantageously, it is the retention feature which retains the upper and lower units together, as opposed to the outer canister of prior art sonobuoys, which therefore frees up space for larger components within the same overall sonobuoy diameter or enables the same components to reduce the overall sonobuoy diameter. A sonar system comprising an aircraft, electronics and a plurality of the sonobuoys is also disclosed.
