Armageddon is a 1998 disaster thriller directed by Michael Bay and starring Bruce Willis as a veteran oil driller who is asked by the US government to join a NASA mission to land on a meteor and plant a nuclear weapon in order to prevent a collision with Earth. The film's cast includes Billy Bob Thornton, Liv Tyler, Will Patton, and Ben Affleck. Armageddon also was released in the same year as the similarly-themed film Deep Impact.
The following weapons were used in the film Armageddon:
Heckler & Koch P7M13
At one point in the film, Colonel William Sharp (William Fichtner) pulls a nickel finish Heckler & Koch P7M13 that was kept in a secret storage locker (it also appears that the gun was stored in the shuttle loaded and loose). Charles "Chick" Chapple (Will Patton) is then led to ask why Sharp needs a gun in space.
There are two separate appearances of Mossberg 590 shotguns in the film. The first is a 590 with a high-capacity magazine tube, bayonet lug, and heat shield on the oil rig where Harry Stamper (Bruce Willis) chases A.J. Frost (Ben Affleck) after catching him sleeping with his daughter Grace Stamper (Liv Tyler), firing several rounds at him before hitting him in the ankle with a grazing shot. The second appearance is a Mariner model, also with a high-capacity magazine, being wielded by FBI agents at a roadblock while trying to catch Jayotis "Bear" Kurleenbear (Michael Clarke Duncan).
Heckler & Koch MP5A3
NASA police are armed with the Heckler & Koch MP5A3.
Several U.S. soldiers can be seen with M16A2s while providing additional security at Cape Canaveral in preparation for the Freedom and Independence shuttle launches.
In addition to drilling equipment, the Armadillo vehicles used on the asteroid are also armed with M61 Vulcans. Following the crash of the Independence shuttle on the asteroid, A.J. uses the Vulcan cannon on his shuttle's Armadillo to shoot apart the fuselage of the crashed shuttle enough to ram through it. Later in the film, Rockhound (Steve Buscemi), under the effects of space dementia, gets a hold of a remote control for one of these weapons and begins to open fire, nearly hitting several of the protagonists before being tackled and disarmed by Harry.
