At that time, the Matador nuclear cruise missile was already deployed in Taiwan. The missile could deliver a 20 kt W5 warhead to a range of about 965 km (600 miles). From Taiwan, the Matador could potentially have hit Chinese troop concentrations around Amoy, but General Twining apparently favored bombs. Nuclear bombs, however, did not arrive in Taiwan until January 1960, but a declassified document previously released to me under FOIA shows they were available on Guam and Okinawa. The bombs included three types – Mk-6 (only Guam), Mk-36 Mod 1, and Mk-39 Mod 0 – with yields ranging from 8 kilotons to 10 megatons (see Table 1).
