The Tactical Technology Office is holding a Proposers Day meeting to provide information to potential proposers on the objectives of the new Manta Ray program and to facilitate teaming. The principal objective of Manta Ray is to open a design space for future unmanned underwater vehicles (UUVs) that are capable of both long duration missions and large payload capacity. A secondary goal of the program is to advance key technologies that will benefit other naval designs such as low lifecycle cost UUV operations, long duration undersea energy management techniques, biofouling reduction technologies, and long duration navigational enablers.
The Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV) program is developing an unmanned vessel optimized to robustly track quiet diesel electric submarines.
Unmanned underwater vehicles (UUVs) have inherent operational and tactical advantages such as stealth and surprise. UUV size, weight and volume are constrained by the handling, launch and recovery systems on their host platforms, however, and UUV range is limited by the amount of energy available for propulsion and the power required for a given underwater speed. Current state-of-the-art energy sources are limited by safety and certification requirements for host platforms.
The Hunter program seeks to develop an innovative concept for the delivery of advanced undersea payloads from extra-large unmanned underwater vehicles (XLUUVs). The Hunter program will be executed in phases. Phase 1 seeks to design and build the payload delivery device to fit inside a government-provided payload module. Phases 2 and 3 aim to support integration of the payload delivery device into the XLUUV and perform testing.
No matter how capable, even the most advanced vessel can only be in one place at a time. U.S. Navy assets must cover vast regions of interest around the globe even as force reductions and fiscal constraints continue to shrink fleet sizes. To maintain advantage over adversaries, U.S. Naval forces need to project key capabilities in multiple locations at once, without the time and expense of building new vessels to deliver those capabilities.
