  • Item Description
    The USA planned to phase out all expendable launch vehicles (ELV) after the Space Shuttle entered service. However, the Challenger accident of 1986 changed all that, and the Delta program was restarted. Termed Delta II, these rockets have made nearly 150 successful launches since 1989, making it the most reliable system in service. Originally built by McDonnell Douglas, production for both US government and commercial entities is now the responsibility of United Launch Alliance (ULA). As an ELV, each rocket can only be launched once. Among the Delta IIs missions are launching GPS Block II satellites, Iridium satellites, and several Mars missions for NASA.

    Delta rockets, including the 7000 series that includes both úLight and úHeavy variants, are given a four-digit code depending on their exact configuration. For example, a úDelta II 7925 Heavy refers to a vehicle that has an RS-27A-engined first stage, nine graphite-epoxy motor (GEM) boosters, a second stage powered by an Aerojet AJ10 engine, and a Payload Assistance Module (PAM) third stage. The úHeavy designation refers to the fact that the system employs the larger GEM-46 boosters that were originally intended for the Delta III. Dragon Space series has launched a fine model of such a Delta II 7925 Heavy rocket. Made to 1/400 scale, it accurately replicates this common launch configuration. The model is sharply molded and finished in the correct colors. The model also comes with its associated launch platform, creating an instant miniature scene that will impress viewers.

    Contains one 1:400 diecast collectible model.
