MagStealth
Overview
MagStealth is an Australian defence technology company established to address a century-old capability gap in naval magnetic signature management. Magnetic deperming has been an essential part of naval survivability since the Second World War, yet the underlying facility designs and treatment procedures have remained largely unchanged for decades, leaving navies dependent on slow, infrastructure-heavy processes that take vessels offline for weeks at a time.
MagStealth was formed to change that. Built around patented Planarised Coil Travelling Wave Deperming Technology, the company has spent more than three years on concept development, engineering design, scale prototyping and stakeholder engagement to bring a step-change capability to market. The flagship StealthDock platform, a Multi-Class Capability Magnetic Treatment Facility, reduces vessel treatment time from weeks to hours while keeping platforms fully crewed, armed and operational. The complementary MagWash platform delivers the same technology to land forces in a mobile, container-based configuration suitable for armoured vehicles, weapons systems and ordnance.
Headquartered in Western Australia and aligned with the Henderson defence precinct, MagStealth is engaged with the Royal Australian Navy, allied Indo-Pacific navies, the United Kingdom Royal Navy, and the United States Navy and Marine Corps. The company works alongside Tier 1 defence primes and shipbuilders to deliver sovereign Australian capability that supports AUKUS, allied force design priorities, and the modernisation of magnetic treatment infrastructure across the Indo-Pacific.
Capabilities
MagStealth’s core capability is the design, engineering and commercialisation of magnetic signature management systems that allow naval and land forces to operate with reduced detectability against modern sensors and magnetic-influence weapons. The company’s two flagship platforms, StealthDock and MagWash, deliver this capability across the maritime and land domains.
StealthDock is a Multi-Class Capability Magnetic Treatment Facility built on patented Planarised Coil Travelling Wave Deperming Technology. It treats fully crewed, fully armed, fully operational vessels in hours rather than weeks, and is compatible with approximately 95 per cent of allied surface and submarine classes, from littoral patrol vessels and frigates through to nuclear-powered submarines and amphibious assault ships. MagWash extends the same technology to land forces in a mobile, ISO container-based configuration for treatment of armoured vehicles, weapons platforms and ordnance at depots, ports of embarkation or in theatre.
Recent defence-industry activity includes: Display of a 1:150 scale working StealthDock model at Sea Air Space 2026 (Maryland) as part of the Team Defence Australia delegation, with priority engagements with US Tier 1 primes and US Navy stakeholders.
Joint development of a magnetic treatment facility white paper for the Royal Australian Navy with a Tier 1 multinational defence partner.
Independent engineering review of the StealthDock berthing system by an internationally recognised marine and subsea engineering firm.
Recognition as a finalist in the IndoPac25 Awards.
Active engagement with the United States Marine Corps in support of Force Design 2030, alongside ongoing dialogue with allied Indo-Pacific navies, the UK Submarine Delivery Agency, and Western Australia’s defence community.
Discriminators
Technology and platform
Patented Planarised Coil Travelling Wave Deperming Technology, the only commercial system applying this approach across both naval and land platforms (Australian Patent 2019399929). Treatment time reduced from weeks to hours with a Collins-class submarine in approximately 3 hours, a Virginia-class submarine in approximately 5 hours.
Vessels treated fully crewed, fully armed, fully operational - no de-arming, no cold-move, no extended out-of-service window.
Single facility compatible with approximately 95 per cent of allied naval classes, from littoral patrol vessels and frigates through to nuclear-powered submarines and LHDs.
Modular, non-seabed-penetrating dolphin berthing with a 50+ year operational design life and the ability to be relocated if operational requirements change.
MagWash, the only mobile, ISO container-based magnetic treatment system for land forces, transportable on NATO and US standard skid loaders.
Independent validation, recognition and memberships
