The P-51 Mustang was a single-seat subsonic propeller-driven military aircraft used on Earth, by the United States of America, during the Second World War. It was well-armed, with six .50 caliber machine guns in its wings. Several Mustangs survived until the mid-22nd century, where they appeared at air shows. (ENT: "Storm Front")
When attempting to land in San Francisco in an alternate timeline, Commander Tucker and Ensign Travis Mayweather were fired upon in their shuttlepod by three P-51s, which Mayweather was able to identify due to having seen this type of craft at air shows. (ENT: "Zero Hour", "Storm Front")

The 1944 sequences in "Zero Hour" were scripted to be set circa 1942, but the visual effects team discovered – after some research – that this type of airplane could not be used in that setting. "We realized there were no P-51 Mustangs in 1942 San Francisco," explained Eden FX staff member Robert Bonchune. "But there would have been P-39-Airacobras and P-38s." Executive Producer Rick Berman decided to set the sequences two years later, so that the P-51s could be included. (Star Trek Magazine issue 118, p. 31)
Although the P-51 Mustangs in "Storm Front" are named as such in on-screen dialogue, they were not scripted to be named on-screen in the episode, as evidenced by the installment's final draft script; Mayweather instead identified them by stating, "Those are planes... with propellers."
For the month of April, in the Star Trek: Ships of the Line (2013) calendar, the painting "Time Bandits" by Alain Rivard depicted the moment when the shuttlepod was attacked by the Mustangs.
