Abstract. We introduce the High-Resolution Double-Echelle Spectrograph (HIRDES), which is planned to be the main instrument for the World Space Observatory Ultraviolet (WSO-UV), a 1.7m UV telescope. Within HIRDES the 102-310 nm spectral band is split to feed two echelle spectrographs covering the UV range 174-310 nm and the vacuum-UV range 102-176 nm with high spectral resolution (R>50000). The technical concept is based on the heritage of two previous ORFEUS SPAS missions. We describe results of the phase-B1 development activities.
