Declassified DIA Report Explores Antigravity for Aerospace Applications

In March 2010, the Defense Act request, systematically reviews theoretical concepts that could enable the active control of gravity for aerospace propulsion. Its central premise is that gravity imposes a fundamental burden on all aerospace transportation: vehicles must carry vast amounts of propellant to overcome Earth's gravitational pull, with the majority of propulsive energy dedicated solely to counteracting that force. The document notes that modern propulsion technology can only achieve passive gravity control—developing thrust to counteract gravity—and that no technology currently exists for active gravity control, which would allow vehicles to negate or manipulate the gravitational field itself.

If such control were possible, the report argues, aerospace vehicles would no longer need to carry the massive fuel fractions required to escape Earth's gravitational well; they could simply "levitate" and optimize propulsion for velocity changes rather than gravity overcoming. The report frames antigravity as a colloquial term for the negation or…
