Early jets would not solve Germany's invasion problem

Would German jet fighters available before the Battle of Britain have made Operation Sea Lion succeed?

They would worsen the air battle for Britain but would not repair Germany's fundamental invasion, naval, and logistical deficiencies.

A mature jet force would increase German speed and interception advantages during the Battle of Britain. Air superiority alone, however, could not create a viable cross-Channel invasion fleet or the logistical structure to sustain an army in Britain. Germany lacked the landing craft, naval control, training, and detailed planning required for the operation. Sea Lion was therefore likely to fail disastrously even before adding the technical and maintenance burdens of early jets.
