  In the era of Extremely Large Telescopes, the current generation of 8-10m
facilities are likely to remain competitive at far-blue visible wavelengths for
the foreseeable future. High-efficiency (>20%) observations of the ground UV
(300-400 nm) at medium resolving power (R~20,000) are required to address a
number of exciting topics in stellar astrophysics, while also providing new
insights in extragalactic science. Anticipating strong demand to better exploit
this diagnostic-rich wavelength region, we revisit the science case and
instrument requirements previously assembled for the CUBES concept for the Very
Large Telescope.
