'Lobster' was a US deception to protect the airfield at Djedjelli near Bougie in Algeria (May/July 1943).
A dummy airfield was established in the same general area to decoy Axis bombing attacks away from the real airfield, to which an important role had been allocated in 'Husky' (i) amphibious assault on Sicily, and its success is attested by the fact that the decoy airfield was attacked by a force of Junkers Ju 88 bombers on 18 June.
