IN SAUDI ARABIA, Feb. 15— Half of the American B-52 bombing raids over Kuwait and southern Iraq are being flown from an airfield in western Saudi Arabia, a senior United States military official said today.

All the countries the United States approached for basing rights hesitated, presumably because of the image of the B-52 as a weapon of indiscriminate bombing based on its use in North Vietnam during the Vietnam War, a reputation the Air Force considers inaccurate and unfair.
