Could long-range Allied aircraft cover HX 106?

What Royal Air Force or American long-range aircraft could support the convoy against the German raiders?

Very few; Britain mainly had limited Wellington-based coverage, and the United States was not yet at war.

The early-1941 setting sharply limits the available long-range aircraft. British coverage depended largely on Royal Air Force types such as the Wellington, and there were not many suitable assets. The United States had not yet entered the war, so American military aircraft could not be treated as part of the escort system. This helps explain why surface battleships still carried so much responsibility in the mid-Atlantic gap.
