Ships from the "Gearing" class were completely torn down and rebuilt from the hull up, including new engines, a much larger combat information center, and new sonar and radar systems. The 21-inch torpedo tubes between the funnels were removed, and the 8-round ASROC launcher (FRAM I only) placed there instead. All 3-inch/50 cal gun mounts were removed, and the after superstructure was used for the DASH's hangar and flight deck, with two new triple Mark 32 torpedo tubes for the 12.75-inch Mk.44 torpedo placed just behind the rear funnel. This modernization was designed to extend the life of the destroyer by at least eight years. Eventually, all but three "Gearing"s received FRAM I or FRAM II conversions.
