The Junk Hawk (ジャンキ ホーク Janki Hōku ) is a large spacecraft owned by Diesel. He and Joey use it to follow Samus and rescue the Special Forces Ship Otowa, for their own agendas - Joey to save Samus, Diesel to gain scrap metal for the Junk Quixote. It resembles a Holtz. To survive the magnetic field of the Beta System's unnamed planet, Diesel used manual controls. The Junk Hawk has a nose Vulcan Cannon, manipulator, and a tank mode for land-travel.
The Vulcan Cannon is likely named after the M61 Vulcan, a hydraulically or pneumatically driven, six-barreled, air-cooled, electrically fired Gatling-style rotary cannon which fires 20 mm rounds at an extremely high rate, and has been a principal cannon armament of United States military fixed-wing aircraft for over fifty years.
