Notable Defence Projects

Queen Elizabeth-Class Aircraft Carrier Design
BMT gained prominence in 2003 when the Secretary of State for Defence revealed the crucial design role of BMT Defence Services in the Future Aircraft Carriers programme. The company provided much of the design expertise within the Thales CVF Team, whose design was taken forward into the alliance with BAE Systems to create what is now the Royal Navy's Queen Elizabeth-class aircraft carrier.

Other Naval Projects

Tide Class (MARS) Royal Fleet Auxiliary Tankers 
Tide Class is a fleet of four tankers built to enhance the Royal Navy's maritime capabilities. The first vessel in the class was commissioned into the Royal Fleet Auxiliary (RFA) service in 2016. The next-generation tankers are part of the Military Afloat Reach and Sustainability (MARS) project and were designed to replace the RFA's ageing fleet of single-hulled tankers.

The vessels are designed by BMT, in cooperation with BMT Reliability Consultants and BMT Isis, and are based on the AEGIR tanker. The Tide Class vessels are intended to provide logistics support and services such as transportation of fuel, fresh water, food, and weaponry to the Royal Navy's warships and vessels deployed around the world.

In addition to maintaining the Royal Navy's bulk fuel replenishment at sea capabilities, the tankers can also conduct constabulary and humanitarian aid missions, as well as provide assistance to NATO and coalition allied forces.

Aurora Engineering Delivery Partnership (EDP) 
Aurora EDP is a partnership between QinetiQ, AtkinsRéalis and BMT and is the UK Ministry of Defence's primary route for procuring engineering services to ensure that necessary systems and equipment, including maintenance and spares, are available when and where they are required to meet Royal Navy and Royal Fleet Auxiliary operational demand. The partnership thus contributes to platform availability, capability and safety, supporting DE&S Ships Domain through the Master Record Data Centre (MRDC), the Ministry of Defence's core facility for ship information configuration services for the Royal Navy and Royal Fleet Auxiliary Surface Ship Fleet.

Royal Fleet Auxiliary’s Fleet Solid Support (FSS) 
Fleet Solid Support Ships are the UK Royal Fleet Auxiliary's modern solid stores replenishment ships- an essential supporting element to the delivery of the Maritime Carrier Strike Group. Fleet Solid Support (FSS) will provide support ships designed to deliver munitions, supplies and provisions to the Royal Navy while at sea. They will provide logistical and operational support, including counter-piracy and counter-terrorism missions and will collaborate with allies on operations.

In January 2023, DE&S awarded a contract worth £1.6 billion to Team Resolute, composed of Harland & Wolff, BMT and Navantia UK, to deliver three Fleet Solid Support ships to the RFA.

The construction of the ships, being built to BMT's design, will take place in both the UK and Spain. Each ship will have a core RFA crew of 101, with accommodation provided for an additional 80 personnel operating helicopters, boats, or performing other roles when required.

The ships are designed with an emphasis on minimising carbon emissions, equipped with energy-efficient technologies to decrease power consumption and are adaptable to reduce their carbon footprint by using low-carbon, non-fossil fuels, and future sustainable energy sources. They are also designed to be adaptable from the outset to achieve a Carbon Zero status by the end of their 30-year operational lifespan.

The production of the first FSS ship is expected to begin in 2025 across three shipyards and all three ships will enter service after final equipment fits and military trials, by 2032.

Team Victoria-Class 
Team Victoria-Class is a partnership involving Babcock Canada, Seaspan Victoria Shipyards, and BMT, providing submarine maintenance and sustainment for the Royal Canadian Navy. Operating under the Victoria In-Service Support Contract (VISSC) since 2008, the team manages the upkeep of the Victoria-Class submarines, focusing on project management, engineering, and supply chain development. The submarines perform strategic military roles, such as coastal surveillance and joint coalition missions. The initiative also supports Canadian industry, Indigenous relations, and academic institutions.

ELMS Contract Award 
BMT was awarded the Engineering, Logistics, and Management Support (ELMS) contract by the Royal Canadian Navy.

Innovations

BMT SPARO Payload Delivery Device 
The BMT SPARO is an innovative payload delivery system developed by BMT for drones, specifically designed for challenging front-line logistics and various other demanding environments. It replaces traditional drone-mounted winches with a novel approach that allows the payload to autonomously descend on a controlled line while the drone maintains a stable hover at a higher altitude.

The BMT SPARO system includes an internally powered cable drum and integrated rotors for horizontal manoeuvrability, providing precise control over the payload's positioning and delivery. This design improves safety and operational versatility by reducing the noise and complexity typically associated with traditional winch systems. It enables drones to perform precise deliveries in situations where direct landing is not feasible, such as hostile environments, disaster relief zones, or ship-to-shore transfers.

While initially developed for defence logistics, the BMT SPARO has potential applications in other sectors, including emergency response, humanitarian aid, and commercial delivery services, where reliable, accurate, and autonomous payload delivery is required. The system's design supports operations in diverse conditions, offering a new solution for aerial logistics.
