A special case of a ballistic trajectory for a rocket is a lofted trajectory, a trajectory with an [[apogee]] greater than the [[Minimum total potential energy principle|minimum-energy]] trajectory to the same range. In other words, the rocket travels higher and by doing so it uses more energy to get to the same landing point. This may be done for various reasons such as increasing distance to the horizon to give greater viewing/communication range or for changing the angle with which a missile will impact on landing. Lofted trajectories are sometimes used in both missile rocketry and in [[spaceflight]].<ref>[https://definedterm.com/a/document/10803 Ballistic Missile Defense, Glossary, v. 3.0], [[US Department of Defense]], June 1997.</ref>
