More than a century of engineering excellence
The history of the Huddersfield site dates back to 1902, when founder David Brown Sr. established the iconic Park Works facility that remains the home of the business today. Over decades of continuous investment, the site has evolved into a modern manufacturing and engineering centre while preserving its historic roots.
Throughout its history, the business has played a significant role in supporting defence programmes. During the First World War, it supplied marine gearing systems, while between 1939 and 1945 it produced more than 10,000 tank transmissions Transmission The function of a vehicle transmission is to adjust the torque and speed, and to transfer engine power to the drive wheels. and supplied the gearing for the legendary Spitfire aircraft. The company also contributed to major naval innovation, including propulsion technologies for HMS Exmouth, one of the first major warships to use gas turbine propulsion.
Today, this heritage continues through the development, manufacture and support of highly specialised transmission Transmission The function of a vehicle transmission is to adjust the torque and speed, and to transfer engine power to the drive wheels. systems that provide the performance, reliability and durability required for modern defence operations.
