The article is about attacking far-future science-fictional manned military spacecraft. For a speculative article like this, spacecraft drive serving a story narrative will need to move human-scale payloads (hundreds or thousands of tons) in human-scale timespans. (Weeks, not years) Therefore, gravities of acceleration, and buckets of delta V. Trajectories planned by pointing at a screen and saying "go there", not waiting six months for the right rocks to line up to give you a gravity assist. Fusion or antimatter rockets, not contemporary technology.
