** ''The Fall of Reach'' states quite clearly that a UNSC destroyer with its engines at 66% power is incapable of accelerating out of Sigma Octanus IV's ~0.5 g gravity well, and that fighting near a gravity well in general is considered crippling for UNSC vessels.<ref>''[[Halo: The Fall of Reach]]'', chapter 21.</ref> ''First Strike'' also states that a UNSC frigate's reactors, and thus the drives they power, have power output in the gigawatt range, consistent with fairly low accelerations.<ref>''[[Halo: First Strike]]'', page 285.</ref> Several other scenes in the novels allude to this being the case, such as when the UNSC ''Iroquois'' accelerates at full speed for at least several seconds and still ends up below the [https://en.wikipedia.org/wiki/Hypervelocity hypervelocity] floor (about 3 km/s), given the lack of explosive vaporization of the hull when it collides with a small Covenant ship.<ref>''[[Halo: The Fall of Reach]]'', chapter 21.</ref> Additionally, most visual depictions of space battles, such as the opening of ''[[Halo 2]]'', ''[[Halo Legends|The Package]]'', and ''[[Halo: The Fall of Reach - The Animated Series]]'' depict UNSC ships as either static or slowly drifting in combat, rather than being able to casually clear their lengths in a few seconds in order to dodge projectiles that consistently take at least that long to reach them. These are all consistent with the repeated mentions that the UNSC's reactors utilize [[deuterium]] fusion. | ** ''The Fall of Reach'' states quite clearly that a UNSC destroyer with its engines at 66% power is incapable of accelerating out of Sigma Octanus IV's ~0.5 g gravity well, and that fighting near a gravity well in general is considered crippling for UNSC vessels.<ref>''[[Halo: The Fall of Reach]]'', chapter 21.</ref> ''First Strike'' also states that a UNSC frigate's reactors, and thus the drives they power, have power output in the gigawatt range, consistent with fairly low accelerations.<ref>''[[Halo: First Strike]]'', page 285.</ref> Several other scenes in the novels allude to this being the case, such as when the UNSC ''Iroquois'' accelerates at full speed for at least several seconds and still ends up below the [https://en.wikipedia.org/wiki/Hypervelocity hypervelocity] floor (about 3 km/s), given the lack of explosive vaporization of the hull when it collides with a small Covenant ship.<ref>''[[Halo: The Fall of Reach]]'', chapter 21.</ref> Additionally, most visual depictions of space battles, such as the opening of ''[[Halo 2]]'', ''[[Halo Legends|The Package]]'', and ''[[Halo: The Fall of Reach - The Animated Series]]'' depict UNSC ships as either static or slowly drifting in combat, rather than being able to casually clear their lengths in a few seconds in order to dodge projectiles that consistently take at least that long to reach them.
