The present invention is directed toward an adapter for launching smaller sized sonobuoys from a standard size sonobuoy launching container. The adapters enable two smaller sized sonobuoys to be disposed within the standard size sonobuoy launching container in series. The adapter includes a diverter mechanism that is configured to launch a first smaller sized sonobuoy when the sonobuoy launching container receives a first burst of air, and launch a second smaller sized sonobuoy when the sonobuoy launching container receives a subsequent second burst of air.
