Whilst the Israelis used both the A-4 single-seat single-engine subsonic light attack jet and F-4 two-seat twin-engined all-weather supersonic fighter-bomber during the Yom Kippur War, use of the A-4's nuclear capability was never envisaged. Nuclear warheads were assembled at the Tel Nof Airbase, but for deployment on F-4 rather than A-4 as told in the novel. This was done on October 8 in such a way that the U.S. got to know of it by the next morning, prompting President Nixon to initiate the same day an immediate air-lifted re-supply to Israel of conventional arms, including tanks and planes to replace losses, in Operation Nickel Grass. Whether any of these nuclear bombs were actually carried during a sortie has never been documented.
