OBJECTIVE: Develop a trace chemical / explosive sensor system for underwater unexploded ordnance (UXO) applications that is effective for TNT and other nitro-based underwater UXO analytes of interest.

DESCRIPTION: Navy Explosive Ordnance Disposal (EOD) response teams encounter a variety of underwater explosive threats including limpet mines, naval mines, underwater improvised explosive devices (UW-IEDs) and other UXO. A trace chemical/explosive sensor system will provide improved classification and identification of suspect underwater targets in missions for which acoustic and/or visual imaging alone are not effective. The chemical sensor package desired from this project will be capable of being integrated into a man-portable remotely operated vehicle (ROV). The goal of this program is to expand the existing trace chemical detection capability to include TNT and other nitro-based underwater UXO analytes of interest, such as RDX, PETN and HMX, as well as home-made explosive (HME) compound such as ammonium nitrate, triacetone triperoxide (TATP), and hexamethylene triperoxide diamine (HMTD). The current state-of-the-art is a single analyte sensor for detection of TNT, which only partially addresses the Navy’s requirement to detect the full range of explosive threats.

PHASE I: Define and develop a concept for a multi-analyte sensor system to detect explosive threat compounds of interest at operationally relevant concentrations in seawater. Perform modeling and simulation to predict effectiveness against TNT and other nitro-based underwater UXO analytes of interest, such as RDX, PETN and HMX, as well as home-made explosive (HME) compound such as ammonium nitrate, triacetone triperoxide (TATP), and hexamethylene triperoxide diamine (HMTD). The weight and volume of the sensor should not exceed 25 pounds and 250 cubic inches. The maximum power requirement should not exceed 2.5 watts. The sensor’s response time should not exceed 2 minutes. The minimum detection limit threshold should be 500 parts per trillion.

PHASE II: Produce a prototype sensor system based on the Phase I work. The prototype will be used to demonstrate and validate the concept developed in Phase I in an operationally relevant environment. The weight and volume of the prototype sensor should not exceed 25 pounds and 250 cubic inches. The maximum power requirement should not exceed 2.5 watts. The probability of detection threshold value is .80 and the objective value is .95. The probability of false alarm threshold value is less than .15 and the objective value is .05. The sensor’s response time should not exceed 2 minutes. The minimum detection limit threshold should be 500 parts per trillion. The sensor reliability should be greater than 80 percent and should operate from the ocean surface to a depth of at least 300 feet.

PHASE III DUAL USE APPLICATIONS: Integrate prototype sensor system into a man-portable ROV and demonstrate detection of underwater UXO chemical signature targets in an operationally relevant environment prior to transition to PMS-408. Private Sector Commercial Potential: Detection of underwater chemicals for pipeline inspection.
