 "Karel Doorman" has the same sensor suite as the s. All sensor systems are housed in an integrated mast, provided by Thales Nederland, called the I-Mast 400, comprising a SeaMaster 400 SMILE air warning radar, a SeaWatcher 100 active phased-array surface detection and tracking radar and the GateKeeper infra-red/electro-optical (EO) warning system.With these systems the ship is able to monitor 140 nm using an Integrated Sensor and Communication Systems (ISCS), also by Thales Nederland.Even though "Karel Doorman" had just finished sea trials and had not yet been commissioned, on 6 November she was sent on a three-month deployment to West Africa to deliver aid to Ebola-struck countries.
