Precision Electro-Mechanical Engineering, Sustainment and Prototype Development for Defence

McMahon Micro is a South Australian Defence engineering company specialising in precision electro-mechanical subsystems, sovereign sustainment solutions, reverse engineering, and advanced prototype development for Defence, aerospace, and high-consequence applications.

We support Defence capability throughout the entire lifecycle—from early-stage concept development and prototype engineering through to sustainment, life-of-type extension, obsolescence management, and the recovery of critical systems where OEM support is limited or no longer available.

Our expertise includes the reverse engineering, redesign, manufacture, assembly, and testing of complex mechanical and electro-mechanical devices used within maritime, autonomous, aerospace, and Defence platforms. This includes precision mechanisms, timing systems, actuation devices, sensor and effector subsystems, and tolerance-critical components where reliability, security, and performance are essential.

Operating as a vertically integrated engineering facility, all design support, CAD, machining, inspection, assembly, troubleshooting, validation, and prototype manufacture are performed in-house. This enables rapid development cycles, secure handling of sensitive projects, strong quality control, and efficient resolution of complex technical challenges.

McMahon Micro maintains a presence across South Australia's key Defence and advanced manufacturing precincts. Our Defence consulting office is located within the Margaret Graham Building at Lot Fourteen, Adelaide's premier Defence and space innovation hub. Prototype development and manufacturing activities are conducted from our engineering facilities within the Tonsley Innovation District, while design collaboration and advanced precision engineering research activities are supported through Adelaide University's Mawson Lakes innovation and research precinct.

Together these facilities provide direct access to South Australia's Defence, research, advanced manufacturing, and sovereign capability ecosystem, supporting the development, sustainment, and enhancement of critical systems that help keep Australia's warfighting capability effective for decades to come.

ENGINEERING FOR HIGH-RISK, EARLY-STAGE DEFENCE SYSTEMS DEFENCE ALIGNMENT, CAPABILITY & SECURE DELIVERY

McMahon Micro provides sovereign Australian capability supporting Defence and advanced technology programs, including work aligned to the Guided Weapons and Explosive Ordnance (GWEO) Enterprise.

Operating from Adelaide, South Australia, we deliver secure, in-house development of small, complex electro-mechanical subsystems for Defence applications where technical risk, performance requirements, sustainment challenges, and confidentiality are critical.

Our work supports both early-stage capability development and the sustainment of legacy systems, including reverse engineering, obsolescence management, life-of-type extension, subsystem enhancement, and validation of precision mechanical and electro-mechanical devices where OEM support may be limited or no longer available.

We support low to mid Technology Readiness Levels (TRL 2–5), concept development, subsystem prototyping, and validation prior to transition to production pathways, while also assisting Defence and industry partners in maintaining critical capability throughout operational service life.

SECURE DEVELOPMENT ENVIRONMENT

Due to the nature of our work, we operate under strict confidentiality and controlled information handling practices:

-All work conducted under NDA-based engagements -Controlled access to design, prototype, and test information -Restricted disclosure of programs, components, and outcomes -Secure handling of sensitive Defence, Aerospace, Maritime and MedTech projects -As part of our transition to Defence Prime engagement, we are formalising governance and security frameworks, including preparation for the Defence Industry Security Program (DISP).

CORE DEFENCE CAPABILITY

-Early-stage Defence prototype development (TRL 2–5) -Reverse engineering and obsolescence management -Life-of-type extension and sustainment engineering -Complex mechanical and electro-mechanical subsystem design -Precision micro-machining across advanced materials -Prototype assembly, integration, testing and validation -Precision manufacture of low-volume, mission-critical components -Rapid concept-to-prototype engineering -Engineering problem solving in high-uncertainty environments -Sovereign, vertically integrated in-house development capability

McMahon Micro provides in-house precision manufacture and assembly to support rapid development of electromechanical subsystems for Defence and advanced technology programs. Our capability is integrated directly into the engineering process, enabling fast iteration, tight dimensional control, and secure handling of sensitive projects.

We specialise in:

• Tolerance-critical mechanical and micro-mechanical components
• Precision sub-assemblies and prototype mechanisms
• Iterative prototype development under NDA and IP constraints
• Low-volume, high-accuracy manufacture for early-stage systems

All machining, inspection, and assembly activities are conducted internally. This allows design, manufacture, and validation to occur as a single controlled workflow, supporting rapid design evolution and reducing development risk.

IN-HOUSE CAPABILITY AND CONTROL

Our vertically integrated approach enables: Rapid design-to-manufacture iteration (hours to days, not weeks) Direct feedback between engineering, machining, and assembly Secure handling of Defence, Aerospace, and MedTech programs Full control of prototype configuration and design changes We do not outsource core machining or prototype development activities, maintaining sovereign capability and protecting sensitive project information.

PRECISION ENGINEERING ENVIRONMENT

Our facilities support development of small, complex systems requiring high accuracy and repeatability, including: Multi-axis precision machining for complex geometries Micro-scale finishing, lapping, and surface control High-resolution metrology and surface measurement Assembly, integration, and functional test capability This capability is applied across both Defence and MedTech domains, where reliability, traceability, and engineering discipline are essential.

ENGINEERING DEPTH AND PRACTICAL EXECUTION

Led by Richard McMahon, a certified master watchmaker and precision engineer, McMahon Micro combines micro-mechanical design expertise with hands-on manufacturing capability. This enables direct translation from concept to physical system, with issues identified and resolved rapidly during development — a critical advantage in early-stage, high-uncertainty programs.

COLLABORATION AND ECOSYSTEM

We operate within South Australia’s advanced manufacturing and research ecosystem, including collaboration with university partners and industry networks. McMahon Micro is a member of: Medical Technology Association of Australia (MTAA) Henderson Alliance Australian Industry and Defence Network Defence Teaming Centre

Precision assembly work carried out in our environmentally controlled micro-engineering workspaces. Complicated machinery assembled by qualified and certified horologists and watchmakers. We have access to clean rooms for assembly at both our Tonsley and Mawson Lakes machining centres for device assembly. Decades of experience manufacturing precision parts for the medical and defence industries. We have a network of advisors and experts in many engineering and design disciplines. We have a proven track record of designing, prototyping and testing devices for our clients in IVF, cardiology and ophthalmology disciplines. Members of AusBiotech biomedical organisation. We work closely with our clients offering quick modifications to our components and devices made by us, in-house.

Our client feedback shows our strength is speed and communication. Keeping costs low by using a vertically integrated lab and workshop like ours can save months in development and many thousands of dollars. We have the capability to work on multiple devices in parallel to fast track testing and evaluation.

We specialise in proof of concept, high quality working devices for venture capital demonstration meetings, potentially enabling access to funding quicker than other methods. Once a device is functioning, certification processes can be carried out. This is how many successful companies work today and is an advantage in the fast moving medical and tech industries.

To support ongoing engagement with Defence Primes, we have formally commenced implementation of an ISO 9001 Quality Management System and are preparing for entry into the Defence Industry Security Program (DISP). This reflects our transition from early-stage prototyping to governed, secure delivery aligned with Defence requirements.
