DeVal Lifecycle Support MHU-110 and MHU-141 Munitions Trailer Design, Manufacturing and Lifecycle Support

‍

MHU-110 and MHU-141 Small Munitions Handling Trailers

Design, Qualification, First Article, Production and Lifecycle Support

DeVal Lifecycle Support provides engineering, manufacturing, quality assurance and program management capabilities for U.S. Air Force MHU-110 and MHU-141 small munitions handling trailer requirements. These trailers are part of the Air Force’s non-powered Munitions Materiel Handling Equipment (MMHE) inventory and support the transport of munitions between munitions storage areas and the flightline.

DeVal’s integrated approach supports requirements review, systems engineering, design analysis, technical data, qualification, first article, production transition, modernization and fielded equipment sustainment.

As a HUBZone-certified small business with 70+ years of service to the Department of Defense, DeVal brings established munitions handling and ground support equipment experience to complex Air Force requirements.

See MHU-141 Modernization in Action

DeVal’s MHU-141 modernization was redesigned for ease of use by maintainers. The modernization addresses maintenance-intensive legacy components with practical upgrades that improve reliability, corrosion resistance, serviceability and lifecycle performance.

Munitions Trailer Support for Air Force Mission Generation

MHU-110 and MHU-141 railers support the movement and positioning of munitions from storage and build-up areas to the flightline. Equipment availability contributes to efficient munitions handling, aircraft loading operations and mission generation.

Aging components, corrosion, recurring maintenance, parts availability and mixed configuration baselines can reduce operational availability. DeVal applies engineering, modernization, manufacturing and sustainment capabilities to address these conditions while improving maintainer efficiency and extending the life of critical support equipment.

Maintenance-Focused Design and Modernization

DeVal’s support equipment modernization approach prioritizes reliability, maintainability, corrosion resistance and reduced scheduled maintenance. Applicable MHU-110 and MHU-141 design and modernization features include:

  • Zero-maintenance steering using stainless steel pins and bronze bushings to eliminate lubrication requirements and prevent corrosion-related degradation
  • Permanently lubricated, sealed wheel bearings that eliminate routine servicing requirements
  • Corrosion-resistant hydraulic components using stainless steel, Teflon-coated hoses and upgraded fittings for resistance to abrasion, moisture and environmental exposure
  • Disc-brake configurations that improve braking consistency and reduce adjustment and maintenance requirements
  • LED lighting and sealed, waterproof electrical harnesses that improve reliability, reduce power draw and reduce replacement cycles

These upgrades are designed to reduce maintenance frequency, improve equipment availability and support consistent performance in demanding operating environments.

Maintenance Provisions and Relative Accessibility

DeVal gives special consideration to the accessibility of critical service items in its approach to next-generation MHU-110 and MHU-141 trailer design. The design supports rapid inspection, adjustment and component replacement by maintainers wearing required protective equipment.

Maintainability provisions include:

  • Critical service items free from obstruction by interfacing components
  • Adjustment and replacement procedures completed without removing unrelated, non-failed components
  • Wheel and tire clearance that provides access to nearby components, including tie rods and brake cables
  • Bundled brake-line routing that supports rapid visual inspection of the complete brake line
  • Lifetime LED lighting that eliminates scheduled lighting-system service intervals
  • Sealed electrical connectors clearly labeled for ease of maintenance
  • Tool-free fuse replacement in an accessible location
  • Clear identification of tool selection, assembly requirements and service warnings to prevent misalignment or improper assembly

Proven Munitions Trailer Manufacturing and Testing: AERO 51E

DeVal’s work on the AERO 51E Series Munitions Trailer demonstrates experience manufacturing and testing munitions handling equipment. The AERO 51E serves as the Navy equivalent to the MHU-141/M and applies DeVal’s zero-maintenance approach to a fielded munitions trailer.

DeVal engineers and production personnel completed four days of testing and retesting on the newly manufactured AERO 51E. The testing video provides a direct view of DeVal’s production and test capabilities.

DeVal Manufacturing and Quality Assurance for Munitions Trailer Programs

DeVal provides turnkey mechanical and electrical manufacturing from its Philadelphia facilities. Work is managed through ISO 9001:2015 and AS9100D-certified quality systems, supported by Nadcap-accredited magnetic particle and penetrant inspection capabilities.
