A novel low cost air-launched sonobuoy having a spherical housing of a lightweight semi-rigid foam housing encapsulated the electronic components. The housing includes recesses for receiving a hydrophone and cable pack, and for inserting D-size batteries just prior to launching. A vertical antenna is wrapped around the housing and prevents the pack from deployment until the sonobuoy is charged with the batteries and immersed in water. The free end of the antenna is released and unwraps to permit deployment of the hydrophone and cable pack. The sonobuoy is stored without the batteries in a sealed moisture-proof envelope which can be easily torn open and removed when desired.
