Mission-Critical Electro-Mechanical Subsystems for Defence & Autonomous Platforms.
Design, development, and secure in-house prototyping of precision timing, safing, sequencing, and actuation systems, including environmentally hardened assemblies for high-consequence applications.
Supporting Defence, Aerospace, Government, and advanced technology programs requiring tolerance-critical performance, functional reliability, and strict confidentiality. Defence R&D & Advanced Prototyping Laboratory.
McMahon Micro is a private applied R&D laboratory delivering end-to-end subsystem development, from concept refinement through to validated prototype assemblies. With an established history of supporting Defence delivery under confidential engagements, we are now available for direct collaboration with Government, Prime contractors, MSPs, and SME partners. We operate in domains where failure is not acceptable, performance is tolerance-driven, engineering judgement is critical, and confidentiality is assumed.
Our work focuses on small, complex electro-mechanical assemblies requiring precision design, controlled manufacture, and iterative validation rather than volume production. Core Capability Areas.
Precision timing and sequencing mechanisms.
Arming, safing, and controlled actuation systems. Environmentally hardened assemblies (shock, vibration, thermal, ingress). Low observable and controlled emission subsystem design (including low RF signature characteristics). Electromagnetic resilience and survivability (EMP-tolerant design approaches and materials selection).
Design alignment with guided and high-consequence system requirements. Miniaturised, tolerance-critical mechanical and electro-mechanical subsystems. Integration-ready components for air, land, maritime, and autonomous platforms. Our subsystems are developed with consideration for both physical survivability and electromagnetic performance within operational environments.
Engineering Approach.
Our work sits at the intersection of precision engineering, safety-critical systems, and regulated technology development.
We collaborate directly with engineering teams to refine functional concepts into manufacturable designs, resolve tolerance stack-up and material behaviour challenges, validate performance under representative conditions, and de-risk subsystem functionality prior to scale-up or production transfer.
We prioritise engineering correctness over throughput, ensuring each component and assembly performs as intended within its operational context.
Secure, Fully In-House Capability.
All machining, fitting, inspection, validation, and prototype assembly is conducted entirely in-house across our South Australian laboratories. This enables complete control over quality and tolerances, rapid iteration during development cycles, secure handling of sensitive programs and IP, and direct communication between design, manufacturing, and validation.
Our environment is structured to support confidential, high-consequence development programs requiring discretion and technical integrity.
Defence Industry Engagement & Sovereign Capability.
McMahon Micro Pty Ltd is listed with the South Australian Government Defence and Space industry supplier directories and operates within the Tonsley Innovation District. We actively support Australia’s advanced manufacturing and technology ecosystem through engagement with industry and research organisations aligned to Defence, Aerospace, and MedTech sectors.
Our work reflects ongoing involvement in environments where traceability, regulatory awareness, and engineering accountability are essential. Engagement.
We are available for confidential discussions with organisations developing or supporting high-consequence systems requiring precision sub-system design, prototyping, and validation.
