Steven Tiffen
Steve Tiffen is a senior naval engineering and shipbuilding advisor with over 40 years of leadership experience across Defence, complex maritime programs and national‑level capability stewardship. His career in the Royal Australian Navy spanned engineering, sustainment, acquisition and enterprise‑level governance, culminating in senior executive roles guiding some of Australia’s most strategically significant maritime capability programs.
Steve has held key leadership appointments across the Capability Acquisition and Sustainment Group and the Naval Shipbuilding and Sustainment Group, including Head Maritime Sustainment, Head Patrol Boats & Specialist Ships, and Acting Deputy Secretary of the Navy Shipbuilding and Sustainment Group. In these roles, he oversaw the sustainment of the Navy’s surface fleet, major ship acquisition programs, and multi‑billion‑dollar contract portfolios central to Australia’s sovereign maritime capability.
His earlier career included pivotal technical and program leadership within the Air Warfare Destroyer Program, where he shaped engineering, sustainment and international industry engagement during one of the nation’s most complex shipbuilding undertakings.
Steve is a Chartered Fellow of both the Institute of Marine Engineering, Science and Technology and Engineers Australia and a graduate of the Australian Institute of Company Directors. His service has been recognised with the Conspicuous Service Medal, appointment as a Member of the Order of Australia, and most recently as an Officer of the Order of Australia for distinguished service to Defence ship construction, acquisition and sustainment.
Today, as founder and director of Arc Fidelis, Steve advises Defence and industry on maritime capability, shipbuilding strategy, sustainment governance, enterprise‑level decision making and strengthening Australia’s sovereign maritime capability.
Examples of work
Enterprise‑Level Fleet Sustainment Reform
Issue
The Navy’s surface fleet sustainment system had become increasingly complex, with fragmented contract structures, inconsistent governance, and rising cost pressures across a portfolio exceeding $2.1 billion annually. Fleet availability was being constrained by misaligned commercial, technical and operational decision pathways.
Process
Steve established a unified enterprise approach, integrating engineering, commercial, operational and industry stakeholders. He introduced disciplined governance, evidence‑based decision frameworks, and transparent performance metrics across 95+ contracts. His leadership style emphasised collaboration, clarity of purpose, and accountability.
Outcome
Under his direction as Head Maritime Sustainment, the organisation delivered improved fleet availability, clearer commercial arrangements, and a more predictable sustainment pipeline. The reform strengthened sovereign sustainment capability, improved industry performance, and provided Defence with a more stable and strategically aligned sustainment enterprise.
Air Warfare Destroyer Program: International Industry Integration
Issue
The Air Warfare Destroyer Program required the integration of a complex international design (Navantia’s F100) into Australia’s shipbuilding environment. Technical alignment, configuration control, and cross‑cultural engineering collaboration were critical risks to schedule, quality and long‑term sustainment.
Process
As the AWD Alliance lead in Spain and later General Manager Technical, Steve built strong relationships with Navantia, established clear engineering and configuration management processes, and ensured seamless communication between Australian and Spanish teams. He balanced technical rigour with cultural awareness and practical problem‑solving.
Outcome
The program achieved successful transfer of design knowledge, improved build quality, and established the foundations for long‑term sustainment of the Hobart Class destroyers. Steve’s leadership was instrumental in bridging international engineering practices and strengthening Australia’s sovereign shipbuilding capability.
Standing Up a National Shipbuilding Workforce and Production System
Issue
The expansion of Australia’s naval shipbuilding enterprise required rapid establishment of production engineering, test and activation, acceptance processes, and workforce capability across both Osborne (SA) and Henderson (WA). The challenge was to unify disparate shipbuilding activities into a coherent national enterprise.
Process
As Director General Naval Construction Branch, Steve implemented structured production governance, strengthened engineering assurance, and aligned shipyard practices across states. He worked closely with industry partners, Defence stakeholders and workforce leaders to embed consistent standards and predictable delivery rhythms.
Outcome
The enterprise delivered the final two Air Warfare Destroyers, improved production maturity, and established a scalable national shipbuilding system capable of supporting future major programs. Steve’s leadership helped shape a more resilient, coordinated and sovereign maritime industrial base.
