Unmanned Underwater Vehicle Independent Test and Evaluation

October 31, 2014
Ervin W, Madden J, Pollitt G, Unmanned Underwater Vehicle Independent Test and Evaluation, Johns Hopkins APL Technical Digest, Volume 32 Number 5 (2014)

The Johns Hopkins University Applied Physics Laboratory (APL) has a long history of contributing to unmanned undersea or underwater vehicle (UUV) programs sponsored by several Navy acquisition program offices. Those contributions span the systems engineering realm, including leadership of independent test and evaluation for prototypes and systems fielded for military use. One of the most enduring relationships has been with Program Manager Naval Sea Systems Command (Expeditionary Missions) (PMS-408) for its acquisition of UUVs applied to mine countermeasures (MCM) missions. Since 2002, APL has served as the independent test and evaluation agent for the Mk 18 UUV family of systems. The fielding of key components of the Mk 18 UUV family of systems was accelerated as part of an Office of the Secretary of Defense “Fast- Lane” program to meet an operational need in theater. As a result, Commander Fifth Fleet now has an improved operational MCM capability, including advanced sensors.

NavSea Warfare Centers: Technical Capabilities Manual

June 1, 2012
NavSea Warfare Centers: Technical Capabilities Manual

Executive Summary

This document lists and defines the current Technical Capabilities of the NAVSEA Warfare Centers.

The NAVSEA Warfare Centers (WC) are composed of the Naval Undersea Warfare Center (NUWC) and Naval Surface Warfare Center (NSWC). Together they cohesively and seamlessly operate the Navy's full spectrum research, development, test and evaluation, engineering, and fleet support centers for offensive and defensive systems associated with surface warfare, undersea warfare and related areas of joint, homeland and national defense systems from the sea.

NUWC has two Divisions with the lead locations in Newport RI and Keyport WA. Keyport Division has a second major site, Naval Sea Logistics Center, in Mechanicsburg, PA. NSWC has 8 Divisions with the lead locations in Carderock MD, Corona CA, Crane IN, Dahlgren VA, Indian Head MD, Panama City FL, Port Hueneme CA and EOD Tech Div in Stump Neck MD. Carderock Division has a second major site, Ship Systems Engineering Station, in Philadelphia, PA, and Dahlgren Division has a second major site, Combat Direction Systems Activity, in Dam Neck, Virginia. To accomplish their mission, the Divisions have specific and unique Technical Capabilities (TCs) which describe the work they perform.

Autonomous Robots in the Fog of War

August 2, 2011
Weiss L, Robots in the Fog of War, IEEE Spectrum, Aug 2011

Networks of autonomous robots will someday transform warfare, but significant hurdles remain

Why haven't we seen a fully autonomous robot that can sense for itself, decide for itself, and seamlessly interact with people and other machines? Unmanned systems still fall short in three key areas: sensing, testing, and interoperability. Although the most advanced robots these days may gather data from an expansive array of cameras, microphones, and other sensors, they lack the ability to process all that information in real time and then intelligently act on the results. Likewise, testing poses a problem, because there is no accepted way to subject an autonomous system to every conceivable situation it might encounter in the real world. And interoperability becomes an issue when robots of different types must interact; even more difficult is getting manned and unmanned systems to interact.

Small Subs Provide Big Payoffs for Submarine Stealth

March 31, 2001
Fox D, Small Subs Provide Big Payoffs for Submarine Stealth, Undersea Warfare, Vol 3, Number 3, Mar 2001

Making submarines quiet, efficient, and effective is our main mission at the Navy’s Acoustic Research Detachment (ARD) at Bayview, Idaho. As an integral part of the Navy’s Research, Development, Test and Evaluation (RDT&E) community – namely, the Carderock Division, Naval Surface Warfare Center under the Naval Sea Systems Command – we execute this mission by operating large-scale submarine models on three ranges in Lake Pend Oreille, Idaho.

Depth Accuracy in Seabed Mapping with Underwater Vehicles

Abstract 

The HUGIN II untethered underwater vehicle (UUV) provides detailed seabed survey services to the offshore industry on a commercial basis. This paper discusses the resulting depth accuracy of the digital terrain model (DTM) that can
be achieved with an UUV using standard commercially available multibeam echosounders, navigation sensors, pressure transmitters, CTD sensors, sound velocity sensors and international standards for computation of salinity and density.
The results are also applicable for remotely operated vehicles (ROV) and towed fish.
