U-TacS was created in 2005 for the purpose of delivering a specific Tactical Unmanned Air System capability to the British Army. 

The Watchkeeper programme has successfully integrated 40 UAVs with world class sensors to an airframe that has consistently demonstrated outstanding performance and reliability all over the world.

From this strong foundation in delivery of Watchkeeper as an essential ISTAR node, UTacS has evolved into a centre of excellence for this technology, that can now offer the next generation UAS to the international market. WK-X can bring a step change in utility for military operators all over the world, yet still retains the outstanding ISTAR capability of the original British Army platform.

We are an agile SME that can draw upon multinational parent companies with a joint global presence in over 70 countries worldwide delivering a joint turnover in excess of $25Bn. We have access to a significant range of relevant technologies such as UAV platforms, avionics and control systems, state of the art surveillance, detection, targeting and intelligence fusion capabilities.
