Abstract
The U.S. Navy’s Yard Torpedo Test Craft (YTT) was commissioned in 1986 to serve as a range craft designed for heavy weight torpedo testing based out of Naval Undersea Warfare Center (NUWC) Keyport. Since the inception of the YTT, missions and tests have changed to align with new technology and goals of the Navy. The focus has shifted to add large unmanned underwater vehicles (UUV) to the primary mission areas. As the mission changed, the YTT was retrofitted to accommodate different testing missions. As the Navy moves into a Distributed Maritime Operation mindset and shifts its focus to unmanned technology, the need to further update this dated test craft to align with new missions is clear. This thesis explores the documentation of both the old and new missions of the craft to highlight where there is a need for update and modification. An analysis into the most feasible alternative to replacing or rebuilding this craft is conducted to justify the follow-on work of the YTT that is suggested throughout the remainder of the thesis. The thesis proposes the implementation of new systems on the existent hull. With this new equipment, the YTT will be capable of multiple-UUV supporting missions through a multi-mission configurable combat systems suite without compromising its already capable torpedo testing mission and extending its operating area. The final product of this thesis is a plan for the new equipage on board as well as an installation and maintenance plan.
