UUV CADDIE: Capture and Deploy Device using Inflatable Elements

One of the missions of the MK VI Patrol Boat is the launch and recovery (L&R) of various unmanned vehicles (UVs). With current L&R systems, operations are difficult and cumbersome in calm conditions, and beyond Sea State 1 (SS-1) the launch of a combat rubber raiding craft (CRRC) is required which further increases risk. Additionally, current L&R systems are not adaptable to multiple UV platforms.Navatek proposes to develop a tethered Capture and Deploy Device using Inflatable Elements (CADDIE) system that combines ultra-lightweight inflatable elements with an aluminum frame and a simple remotely operated thruster (ROT). The UUV CADDIE uses proven ultra-lightweight inflatables for “soft” UUV capture at a low stowed space/weight, and a COTS thruster for maneuverability at low-cost, to enable reliable recovery of UUVs without deploying a CRRC or divers in sea-state 4+ and in full darkness.This project uses proven inflatable technology being developed under three successful ongoing Navy programs that involve securing underwater and surface vehicles using compliant inflatables. Directly relevant at-sea test data on these inflatable systems is available, reducing the development risk and cost of the UUV CADDIE system.
