This feature is labelled to distinguish Australian, UK, international, historical and externally reported activity. Those contexts are not interchangeable.

Capability validated aboard HMS Trent

The UK Ministry of Defence formally confirmed in Parliament that trials of the Helicopter Visual Landing Aid System (HVLAS) aboard HMS Trent were successful.

The trials followed installation of the system on the Batch 2 River-class Offshore Patrol Vessel. Over three days, a Royal Navy Wildcat helicopter conducted rigorous day and night landing tests. The Ministry of Defence said the testing showed the technology to be effective, moving the system beyond an installation milestone to an operationally tested shipboard capability.

“The recent trials of the Helicopter Visual Landing Aid System (HVLAS) onboard HMS Trent was a success.”

From Trent to Spey

The significance of the HMS Trent trial is clearest in what followed. In the same Parliamentary answer, the Ministry of Defence stated that, as a result of the successful testing, it planned to fit HMS Spey with HVLAS when the vessel entered scheduled refit.

HMS Trent and HMS Spey are both Batch 2 River-class Offshore Patrol Vessels. The stated progression is therefore direct: installation and testing aboard HMS Trent, formal confirmation of success, then a planned installation on the next vessel.

A wider Batch 2 direction

A later Ministry of Defence answer, published on 18 October 2025, set out the wider programme direction. It said the planned timeline for installing Glamox HVLAS across the remainder of the Batch 2 Offshore Patrol Vessel fleet was aligned with the platforms’ five Annual Recertification Maintenance Periods.

The answer allowed for work to be advanced where operational requirements, funding or timing created an opportunity. Read chronologically, this later statement continues the programme beyond the Trent trial and planned Spey installation; it is supporting evidence for wider fleet intent rather than the primary validation event.

du Pré Marine’s documented role

Glamox states that its HVLAS aboard HMS Trent was installed in 2025 by its customer du Pré Marine. The same account says Glamox worked closely with the UK Ministry of Defence’s Defence Equipment & Support organisation and the vessel’s through-life support contractor, UK Docks Marine Services.

UK Docks separately describes a wider collaborative work package spanning planning, procurement, design approvals, installation, set-to-work, commissioning and trials. These sources document du Pré Marine’s place in the delivery and installation environment; they do not suggest that du Pré Marine designed or manufactured HVLAS, and the Parliamentary record validates the capability rather than endorsing du Pré Marine itself.

For an Australian maritime audience, the relevance lies in experience across the practical shipboard stages between equipment supply and operational use: integration, installation, commissioning, OEM coordination and ongoing technical support. The HMS Trent work forms part of the wider du Pré Marine UK and international record and is not presented as an Australian contract.

Measured at sea

Successful shipboard integration is ultimately demonstrated in operation. The HMS Trent programme provides a clear sequence from installation and commissioning through rigorous flying trials, formal capability validation and subsequent fleet planning.
