'Williams' (i) was a US radio cover operation for Lieutenant General Omar N. Bradley’s US 1^st Army in the approach to 'Overlord' (9 May/6 June 1944).

'Williams' (i) simulated the 1^st Army’s radio net between 9 May, when the real network closed, and 6 June when it went on the air once more as 'Overlord' began. 'Williams' (i) was therefore the US counterpart of 'Quaker', which provided similar cover for Lieutenant General Sir Miles Dempsey’s British 2^nd Army.
