  In this note we continue our study of unidirectional solutions to
hydrodynamic Euler alignment systems with strongly singular communication
kernels $\phi(x):=|x|^{-(n+\alpha)}$ for $\alpha\in(0,2)$. The solutions
describe unidirectional parallel motion of agents governing multi-dimensional
collective behavior of flocks. Here, we consider the range $1<\alpha<2$ and
establish the global regularity of smooth solutions, together with a full
description of their long time dynamics. Specifically, we develop the flocking
theory of these solutions and show long time convergence to traveling wave with
rapidly aligned velocity field.
