H-IIB (H2B) is an expendable launch system used to launch H-II Transfer Vehicles (HTV, or Kounotori) towards the International Space Station. H-IIB rockets are liquid-fuelled with solid-fuel strap-on boosters and are launched from the Tanegashima Space Center in Japan. Mitsubishi and JAXA have been primarily responsible for design, manufacture, and operation of H-IIB.
Kounotori 4, also known as HTV-4, was the fourth flight of the H-II Transfer Vehicle, an unmanned cargo spacecraft launched in August 2013 to resupply the International Space Station. It launched from Tanegashima Space Center aboard H-IIB rocket on August 3, 2013 and connected to ISS by August 9, 2013; it carried 5.4 tons of cargo. Kounotori 4 undocked on September 4, 2013 and was destroyed by reentry on 7 September 2013.
