This Defense Intelligence Reference Document (DIA-08-1003-018), dated 30 March 2010, was produced by the Defense Intelligence Agency as part of its FY 2009 Advanced Aerospace Weapon System Applications (AAWSA) Program. It reviews theoretical approaches to antigravity for aerospace propulsion, drawing on Newtonian physics, general relativity, cosmological dark energy and quantum vacuum effects. The report notes that no current technology can actively control gravity and that many concepts are far from practicable engineering.

One should note the striking similarity between Equations (4) and (5) for the dipole electric and dipole gravitational fields. Figure 2. Diople Gravitational Field Generator (Reference 14) Using Equation (5), Forward (Reference 13,14) showed that there would be a need to accelerate matter with the density of a dwarf star through pipes as wide as a football field wound around a torus with kilometer dimensions in order to produce an antigravity field (at the center of the torus) of G"' 10 10a.,n·, where a.,,c is the acceleration of the (dwarf star density) matter through the pipes. The tiny factor 10-10 is composed of the even smaller 110, which is the reason why very large systems are required to obtain even a measurable amount of acceleration. To counteract the Earth's gravitational field of 1-i requires an antigravity field of 1-i (vectored upward), and thus the dwarf star density material within the pipes must achieve aac, = 10 11 m/s2 in order to accomplish this effect. Forward (Reference 5) also identified a configuration comprised of a rotating torus of dense matter that turns inside-out like a smoke ring as another type of dipole gravitational field generator. As shown in Figure 3, an inside-out turning ring of very dense mass (M) will create an upward force (of acceleration a) in the direction of the (constant) mass motion (Mv, vis the mass velocity). This is also a feature of the 1 The vacuum "gravitational permittivity" constant is (Reference 12): -:-n = (4nGJ- 1 = 1.19 x 109 kg-s 2/m 3 . 6 UNCLASSIFIED//509 AEEJCJOP 1!S5 ADIi X
