In the first deployment in Europe of the CVN-77 George H.W. Bush, the Spanish AEGIS frigate F-102 Juan de Borbon (the never-king father of Juan Carlos I) is integrated for a month in the CVN-77 CVBG (named GHWB Carrier Strike Group in this case):

I remember it's not an unusual situation, that is not the first time a F-100 series frigate is integrated in a CVBG.

Also, I constate the usual escort from a time ago in a CVBG is 2xCG Ticonderoga and 2xDDG Arleigh Burke, but see also: http://www.public.navy.mil/airfor/cvn77/Pa...sSquadrons.aspx

Training off the coast of England, according to the article organized by the royal navy.
