When Bud finishes his conversation with Howie Black, he is standing on a star on the Hollywood Walk of Fame and remarks "Wow, the Quantum Leap guy". The star is for Donald P. Bellisario, the creator of Quantum Leap (1989) and, of course, JAG.
The fictional warship here is USS Wake Island (LHA-6). The real USS Wake Island was CVE-65, an escort carrier of the Casablanca class, which served 1943-46. The real LHA-6 is USS America, the fourth vessel of the US Navy to bear that name and the lead ship in a new class of amphibious assault (helicopter) ships, now under construction, scheduled to become commissioned in 2013.
