Observational data in the ultraviolet wavelength region of the electromagnetic spectrum (120-300 nm) are a powerful tool for studying many astrophysical objects such as exoplanets, especially for determining the characteristics of their atmospheres. Numerous publications on exoplanetary research in leading astronomical publications, prepared in recent years on the basis of realized applications for observations on the instruments of the Hubble Space Telescope (HST), which is the main telescope for spectroscopy in UV, indicates its high demand by the astronomical community. Work is underway to create an orbital space observatory "Spektr-UF" (World Space Observatory - Ultraviolet), which will be the successor of the HST. The Institute of Astronomy RAS is the Lead scientific organization for this project and University Complutense of Madrid is the main WSO-UV partner. Within the framework of this research, work is planned to determine the characteristics for creating instruments for ground-based mission support, to develop tools for preparing applications for the observation program, to develop a program for scientific research of the project. In this paper we discuss spectroscopic and imaging instrumentations of Russian telescopes to be used as project ground support.
