Navies are adapting to the most significant changes in a generation, as shifting geopolitical conditions combine with emergent digital technologies.
Those navies that can adapt, harnessing their existing assets while integrating autonomy, artificial intelligence and enhanced connectivity, will be primed to succeed in this new era.

Your trusted force multiplier
Naval success is no longer measured by the size of your fleet, but by how it is deployed. LR helps deliver enhanced operational readiness and projection, guiding you from the crewed fleet of today to the autonomous systems of tomorrow.
Present at the forefront of every significant naval shift for over 150 years, tested in every naval environment and grounded in structural independence. LR was the first classification society to publish dedicated Naval Ship Rules, refined continuously over 25 years across a diverse range of vessel types and leading navies.
Over the last 30 years, more than 400 naval vessels have been built to LR Class, including 190 to LR's Naval Ship Rules across 19 navies. More than 100 vessels are maintained in Class today across 13 navies, including the Royal Navy, Royal Australian Navy and Royal Canadian Navy.
That long history of standard-setting informs not only established programmes, but also the emerging assurance frameworks being developed for autonomous systems and hybrid fleet operations.
