The AUVfest 2008 expedition used the torpedo weapons recovery vessel, or TWR-841, for hauling and launching AUVs. The vessel has an A-frame on the back, which can hoist large AUVs, like the 550-pound battlespace preparation autonomous underwater vehicle (BPAUV). Aninflatable boat works with the TWR-841, launching the small AUVs, or “fish.” Image courtesy of AUVfest 2008: Partnership Runs Deep, Navy/NOAA, OceanExplorer.noaa.gov
