My source, (ex-USN, alas no longer with us) always maintained that President Reagan ordered the USS America (Kitty Hawk Class) to sail from Newport News to ' the northern end of the South Atlantic' to a: Deter the Soviet Navy from taking 'an interest' and b: To be handy 'just in case' the RN lost a carrier.
Unlikely to be proven, but a Google search brings up this

To my mind, still not proof.
