The Fw 190 in 1940, that is equivalent of the Fw 190 in 1941, still has the same short radius and a very troublesome engine. The 190 was on the verge of being cancelled in 1941 even though it never ventured much above the Chanel.
British can keep out of the reach ( LW can bomb the corner of Kent closest to France to their heart content), pounce the retreating LW - there is no enough of fuel left both for combat at the return leg and to actually make it to home - and the Spitfire III actually materializes.
