'Anvil' (iii) was the US counterpart of 'Aphrodite' (ii) using time-expired and/or obsolescent Consolidated B-24 Liberator four-engined heavy bombers, adapted as explosive-filled BQ-8 drones, to be flown into their targets by remote control (1944).

Several experimental conversions were made, but the BQ-8 was used operationally only once, on 12 August 1944, before the programme’s termination. Flown by the 562^nd Bomb Squadron of the US 8^th AAF, based at RAF Honington in the county of Norfolk, the BQ-8 was to be aimed at a V-1 flying bomb launch site in the Pas de Calais, but was lost together with its passage crew when its payload of Torpex explosive detonated prematurely.
