Multiple videos show, during the night, Ukraine has attacked the military airbase near the city of Dzhankoi in Russian occupied Crimea.
This attack happened 150 km from liberated territory, meaning it is outside GMLRS range, but perhaps within range of the GLSDB glide bombs, or alternatively within range of the larger ATACMS missiles (all of which can be fired from the HIMARS launchers).
Multiple secondary explosions can be heard, so something was definitely hit.
@randahl@DeeGLloyd Nitpick: HIMARS is the launch system. GLSDB are also fired from HIMARS, as far as I know.
The 'old' HIMARS missiles are called GLMRS.
Additionally, HIMARS is just the best known MLRS launcher Ukraine has. MARS and MARS II - which are tracked versions - can fire the same missiles.
