The USS Hemingway was a starship mentioned in a script of Star Trek Nemesis, but not seen in the final version of the movie.
In the script, the gathering to commemorate Data and the final exchange between Picard and B-4 are set just hours after the battle, not at the spacedock. Picard's conversation with B-4 ends because he is informed that the Hemingway has arrived to tow their ship back to spacedock.
