## What project 3447 buys

Funding supports the development of unmanned systems for the Navy's expeditionary unmanned underwater Explosive Ordnance Disposal (EOD) and Mine Countermeasures (MCM) capability. Specifically, it provides for development of affordable expeditionary remote stand-off underwater systems to support Navy Expeditionary forces including EOD, Mobile Diving and Salvage, Underwater Construction Teams (UCT), and Expeditionary Mine Countermeasures (ExMCM) mission operations. The equipment must be highly portable in order to support the Navy EOD technician to safely detect, approach, render safe, recover, exploit, and dispose of underwater explosive threats to include sea mines, limpet mines, maritime IEDs, and unexploded ordnance. Provides support for the Navy's high priority missions of Maritime Homeland Defense and MCM. This project directly supports Department of the Navy Strategic Roadmap for Unmanned Systems promulgated in March 2018 and addresses capability gaps defined by the Joint Service EOD (JSEOD) Initial Capabilities Document (ICD), Serial Number 671-75-05 of 3 June 2005, Joint Improvised Explosive Device (IED) Defeat Initial Capabilities Document (ICD) of 23 February 2006/JROCM 070-06, and the Expeditionary MCM ICD of June 2017. This project is being executed in accordance with approved CNO N9I Requirement #056-95-19, "Capability Development Document (CDD) for Maritime Expeditionary Standoff Response Family of Systems (MESR)," July 23, 2019. Additional efforts continue to execute the open competition process necessary to acquire and verify an EOD Response ROV capability focusing on user effectiveness and operational suitability to provide a ROV based target interdiction capability to address the capability gaps assessed in the previously conducted Expeditionary UUV Neutralization System (EUNS) AoA. This next generation capability is developed to decrease risk when reacquiring/investigating a potential threat (i.e. sea mine or maritime IED). In response to emergent maritime threat assessments ISO of INDOPAC Global Power Competition (GPC) scenarios, the MESR Program of Record (PoR) will conduct a Proof-of-Concept effort, closely partnered with operational forces, to demonstrate the potential ability to counter deep-water explosive threats as an ExMCM enabling capability ISO Joint Force Maneuver, in place of the Avenger-class MCM ships.

**R-3 lines of work:** Product Development; Support; Test and Evaluation; Management Services.

### EOD Response ROVs and Maritime Expeditionary Standoff Response System of Systems

FY27 efforts will continue to focus on test and evaluation of future increment candidate payloads for integration into future MESR increment platforms to allow warfighters to detect, classify, and prosecute explosive threats by ExMCM forces. Efforts include advancement in Artificial Intelligence and Machine Leaning (AI/ML) technologies…
