The name of the specific boat used in the movie Act of Valor isn't identified, either in the movie, director's interview, or the credits for security reasons. However, since it was obviously an Ohio-class boat, an SSGN (as stated in the interviews) and rigged for SEAL insertions, it has to be one of 4 Ohio-class SSGN's:
USS Ohio (SSGN-726)
USS Michigan (SSGN-727)
USS Florida (SSGN-728)
USS Georgia (SSGN-729)
