Derek Lane & Co is a leading supplier of reliable components and solutions to large MOD OEMs in the naval ship-building and marine hydraulic maintenance markets. 

In 2017, we became part of the largest fluid power group in the UK, and as a result have access to the widest and deepest stock levels in the UK, housed at our Group logistics facility in the North West. We can quickly and reliably supply products on a scheduled call-off basis for refit projects or on a next day service for more urgent requirements. 

We partner with some of the world’s largest distributors in the defence arena, supporting applications such as ship davits, door actuation, landing craft, pump rooms, ship stabilisation and weapons systems.
