Thales in the UK has a long and proud heritage stretching back over 140 years. Our success has been driven by bringing together many of the UK鈥檚 most advanced and innovative businesses and technologies spanning three centuries.
Take a tour through our history and discover the renowned brands and achievements that have made Thales one of the most important and forward-thinking technology and engineering businesses in the UK today.

1888
The first Optical Rangefinder
A patent is granted to Professor Archibald Barr & Dr. William Stroud for their optical rangefinders 鈥 a tool that can determine the distance to a visible object.
Together they form Barr & Stroud and become the UK leaders in optical rangefinders winning a contract to supply the British Army and later, the Royal Navy.
113 years later, Barr & Stroud Ltd becomes Thales Optronics Ltd.

1943
Dam Busters success
The bouncing bomb used to destroy the Mohne Dam during World War Two was the first of its kind to bounce across the water and detonate exactly at the point it reached its target.
This success was, in part thanks to the sights made by Barr and Stroud (now Thales Optronics) and the fuse, manufactured by EMI (now Thales Land Systems).

1956
Racal delivers its first radio (the RA-17) to the Royal Navy
Utilising techniques still employed by modern digital receivers to overcome frequency drift, the RA17 design was used by all UK Military services and was to become the main receiver of the British radio surveillance organisation known as G.C.H.Q.
44 years later, Racal would become a Thales company.

1978
A world-first in Periscope Technology
Thales supplies the world鈥檚 first Thermal Imaging Periscope to the Royal Navy, followed a year later by the world鈥檚 first Laser rangefinder Periscope.
The development of this technology solved two critical problems. Firstly, the IR sensor no longer needed a window which could withstand diving pressures and secondly it needed no maintenance during a boat mission.
A single power telescope provided a field of view of 6鈦 x 3鈦.

1982
Ground breaking Jaguar-V radio invented
The Racal group, now Thales Land Systems, starts selling the world鈥檚 first frequency-hopping military very high frequency (VHF) radio, Jaguar-V. It had been developed to resist jamming and used a scrambler, ensuring sensitive information could be relayed safely. The Jaguar-V had up to 50 radio nets and a short range of up to 20km with a long antenna.
By the end of its service in the late 90s, 40 nations, including NATO, were using the Jaguar-V radio.1982
A new standard in visual simulation
Rediffusion Simulation introduces a new standard in visual simulation realism called Wide-Angle Infinity Display Equipment (WIDE). Unlike previous visualisation methods, it uses a spherical mirror to allow distant-focus collimated viewing in a continuous, seamless, horizontal display for pilots seated side-by-side.
In the years following this breakthrough, Thales has developed the technology to accommodate the ever-increasing field-of-view requirements. Today, collimated cockpit displays are standard across regulatory level C and D full-flight simulators.
