Sources Sought for the Repair Technology Exercise (REPTX): Train-REX

June 25, 2026

Introduction: Field, Learn, Adjust, Repeat

The Navy Expeditionary Sustainment and Repair (NESAR) team, part of NAVSEA’s Engineering Directorate Technology Office (NAVSEA 05T), is seeking innovative industry partners to participate in Train-REX. This Repair Technology Exercise (REPTX) is focused exclusively on identifying and validating world-class training solutions for the sustainment, repair, and maintenance technologies used in both expeditionary environments and shore-based naval maintenance facilities.

This is an unfunded opportunity; participants will be expected to cover their own costs. In exchange, the US Navy is offering a significant and unique return on investment. Selected partners will receive unparalleled access to Navy subject matter experts and the next generation of fleet-ready expeditionary technologies within a hands-on naval industrial facility. This provides a platform to gain credible, third-party validation of participants’ training technology and, if identified as possessing a successful solution, be identified as a preferred training package developer for current and future NAVSEA 05T transitioning capabilities.

The goal is to solve a persistent fleet-wide readiness gap by ensuring that no new technology is delivered to the warfighter without an effective training solution to accompany it. The NESAR team invites partners with innovative training services and technologies to collaborate in this high-value effort.

Event Overview & Structure

Train-REX will be a two-phase exercise designed to first develop and then validate the effectiveness of training packages in a realistic environment. This event will be held at the Naval Undersea Warfare Center (NUWC) Division Keyport, Keyport, WA.

Participation as an industry partner requires commitment to both phases of the event. The event is structured as a round-robin, with the assumption that each selected industry partner will develop a training solution for all six technology capabilities presented.

• Phase 1: The “Build” Phase (Week of September 14, 2026)
  Selected industry partners will work on-site at NUWC Keyport to capture the data needed to build their training solutions. The week will be highly structured: from Tuesday through Thursday, there will be six dedicated sessions (morning and afternoon). During these sessions, industry partners will rotate through all six technology stations, working directly with the technology’s subject matter experts (SMEs) to get hands-on experience with the equipment and gather all necessary information (3D scans, operational videos, maintenance procedures, and expert knowledge).
• Phase 2: The “Validation” Phase (Week of November 2, 2026)
  Industry partners will return to NUWC Keyport to validate the training solutions developed after Phase 1. This phase will again be structured as a round-robin, where groups of sailors, reservists, and shipyard personnel will rotate through the six training stations. Each industry partner will be responsible for instructing these users on a specific technology, using only their created training materials. The original technology SMEs will not be present. This phase is the critical test to determine if the training solution is a truly effective, self-sufficient, turnkey product.

Technology Capabilities in Scope

The NESAR team is seeking training solutions for six capability areas. The following list is representative of the types and complexity of technologies that will be featured. While the NESAR team will endeavor to provide this exact equipment, the final list is subject to change based on availability (e.g., the repair products may be swapped for an unmanned undersea vehicle (UUV)).

1. Nitrogen Generation Containers: Large, containerized systems.
2. Alternative Power Generation and Storage: The Nabors hydrogen-based power system.
3. Confined Space Monitoring: Portable atmospheric monitoring kits.
4. Distance Support Kits: Deployable kits for remote assistance.
5. Flange Facing Machines: Portable machines for repairing pipe flanges.
6. Repair Products: Composite-based repair solutions.

Scope of Required Training

To set clear boundaries and expectations, the training developed by industry partners should focus on the common tasks a sailor or Marine would need to perform to get the equipment running and safely secured. The training should not cover deep, expert-level operational use or component-level repair.

• Example: For a containerized solution like the Nitrogen Generator, the training scope would include how to set it up upon arrival, how to perform pre-operational checks to ensure it is operational, and how to properly secure the system for storage or shipment. The training would not need to cover the chemical processes of nitrogen generation or how to repair the internal industrial plant equipment.

Submission Requirements

Submissions will be evaluated based on training effectiveness (demonstrated through industry partners’ playable samples, meaning an existing training product they have developed), technical capability to rapidly develop turnkey solutions, operational practicality for austere environments, development timeline feasibility, and cost-effectiveness. Industry partners are invited to use their written proposal to articulate their competitive advantages and provide specific examples of relevant experience developing training for complex technical equipment, particularly explaining why their approach is uniquely suited to solve the fleet’s technology adoption challenge within Train-REX’s two-phase structure.

To be considered for Train-REX, interested industry partners must submit a package containing the following information. While it is preferred that partners can create a training solution for all six capabilities, it is not a mandatory requirement.

1. A Playable Product Sample (Mandatory): The most critical requirement is access to a playable sample of an existing training product they have developed. Submissions without a sample that the NESAR team can evaluate will not be considered. Please provide a URL or clear instructions for access.
2. A Written Proposal (RFD Attachment): Your proposal must be a single PDF document that details your company’s approach and experience. To ensure a consistent and fair evaluation, your proposal must address the following points:
