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.
Benefit: The CADDIE is being developed with a specific customer in mind: Naval Expeditionary Combat Command (NECC). We will focus on commercializing this product by first transitioning the CADDIE to NECC, and then subsequently adapting it for other customers and applications. Navatek understands from correspondence with the TPOC that the Navy has a significant number of Mk18 Mod2 UUVs already and expects to acquire more soon. This platform will be the focus of the first CADDIE prototype. In addition, the CADDIE design could be used to launch, retrieve, lift, stabilize, and tow a wide range of UUVs. Based on Navateks related work experience that has demonstrated this capability, it is possible to adapt the CADDIE to support launch and recovery operations of small unmanned surface vehicles (USVs) from larger vessels. This project will aim to transition a unique product that can launch and retrieve a wide variety of unmanned vehicles. In addition, the enabling technologies such as the ultra-lightweight, drop-stitch inflatable systems will be further developed, and its technical readiness level will be advanced.
