The Council's members have included defense industry executives and militarist political figures, including Charles Kuppermana former Boeing vice president for its Missile Defense Systems; Douglas Graham, an executive at Lockheed Martin; Amoretta Hoeber, a former TRW executive; former Rep. Curt Weldon (R-PA); Robert Joseph; Phyllis Kaminsky; and Fred Ikle.
Ebner participated on the CSP Roundtable on the B-2 Bomber, which was produced by Northrop Grumman. The Roundtable report advocated the continued production of the B-2 because of "the continuing requirement for a robust nuclear deterrent."
