宇宙ステーション補給機
Unpiloted ships like the SpaceX Dragon, Orbital ATK Cygnus and Japanese H-II Transfer Vehicle include a standard FRGF which is used by the Canadarm2 to grapple the capsule on approach to the International Space Station for berthing. The fixture can have a maximum payload rating of 65,000 pounds or 30,000 kg. An orbital replacement unit may also have a grapple fixture.
