  In this paper, we investigate existence of global-in-time strong solutions to
the kinetic Cucker--Smale model coupled with the Stokes equations in the whole
space. By introducing a weighted Sobolev space and using space-time estimates
for the linear non-stationary Stokes equations, we present a complete analysis
on existence of global-in-time strong solutions to the coupled model, without
any smallness requirements on initial data.
