Advanced Armor Research Group (AARG) is a privately-held American company that provides technical support for US military vehicles and platforms for Soldiers, Marines, Sailors and Airmen. Our team provides the technical knowledge for materials, manufacturing and assembly processes required for customer projects. We also provide on-site program management and Software Configuration Management (SCM) support, as well as procuring materials to meet project needs.

• Provides mechanical drafting, design, and engineering support for warhead development, prototyping, fabrication, integration, testing, qualification, and production activities.
• Develops, revises, and maintains detailed mechanical engineering drawings, 3D models, assemblies, subassemblies, components, and associated technical documentation.
• Uses SolidWorks and Creo to develop and modify 3D models, parts, assemblies, and 2D engineering drawings supporting mechanical design and prototype development.
• Uses Windchill to support management of engineering product data, CAD files, drawings, revisions, documentation, and associated product lifecycle information.
• Translates engineering concepts, sketches, calculations, redlines, test configurations, as-built conditions, and technical direction into accurate mechanical models and engineering drawings.
• Works collaboratively with mechanical engineers, systems engineers, project engineers, test engineers, technicians, machinists, manufacturing personnel, E7 Quality Assurance (QA), Configuration Management (CM), and project/program management throughout the engineering lifecycle.
• Provides drafting and engineering support during design development, design maturation, prototype builds, system integration, troubleshooting, testing, qualification, and transition toward production.
• Supports mechanical design activities involving component interfaces, fit, form, function, assembly requirements, materials, tolerances, fasteners, hardware, and manufacturing considerations.
• Develop detail, assembly, subassembly, interface, installation, and other mechanical drawings required to support fabrication, assembly, testing, and system integration.
• Develops and maintains drawing trees, Bills of Material (BOMs), parts lists, assembly structures, and other product definition information.
• Applies applicable engineering drawing practices, including ASME Y14-series standards and Geometric Dimensioning and Tolerancing (GD&T).
• Reviews engineering drawings and CAD models for technical accuracy, completeness, dimensional consistency, proper tolerancing, drawing relationships, manufacturability, and compliance with applicable engineering requirements.
• Identifies drawing discrepancies, dimensional conflicts, tolerance issues, missing information, interface concerns, incorrect references, and other technical documentation issues and coordinates resolution with the appropriate engineering personnel.
• Supports engineering and technical reviews, including System Requirements Reviews (SRRs), Preliminary Design Reviews (PDRs), Critical Design Reviews (CDRs), Test Readiness Reviews (TRRs), Production Readiness Reviews (PRRs), and other project-specific technical reviews.
• Supports prototype fabrication and testing by incorporating approved engineering redlines, design updates, lessons learned, test-driven changes, and as-built configuration information into engineering documentation.
• Supports development and maintenance of Technical Data Packages (TDPs), including engineering drawings, CAD models, BOMs, specifications, parts lists, and supporting technical documentation.
• Provides engineering documentation support for Engineering Change Proposals (ECPs), Requests for Variance (RFVs), drawing revisions, design changes, and other configuration change activities.
• Works closely with Configuration Management to ensure drawing numbers, revisions, drawing relationships, release status, configuration identification, and associated technical documentation remain accurate, controlled, and traceable.
• Supports CM in maintaining consistency between SolidWorks models, released drawings, Windchill data, BOMs, specifications and technical documentation.
• Supports establishment and maintenance of product baselines as designs mature from development and prototype configurations toward qualification and production configurations.
• Supports Functional Configuration Audits (FCAs), Physical Configuration Audits (PCAs), and other configuration verification activities by providing accurate drawings, models, BOMs, and product definition information.
• Reviews and updates existing or legacy engineering drawings to incorporate approved design, manufacturing, test, and configuration changes.
• Supports prototype-to-production transition by ensuring engineering drawings, CAD models, and supporting technical data mature with the hardware design.
• Coordinates with engineering, testing, E7 QA, CM, and other stakeholders to resolve drawing, CAD, interface, fabrication, and hardware configuration issues.
• Maintains engineering drawings, models, and associated technical data within approved government repositories and product lifecycle management systems.
• Supports proper handling of Controlled Unclassified Information (CUI), export-controlled technical data, distribution-controlled information, and other protected technical information in accordance with Scientific and Technical Information Officer (STINFO) / applicable requirements.
• Supports a rapid weapons development and prototyping environment while maintaining appropriate engineering rigor, drawing quality, technical documentation, configuration control, and traceability.
