This addon provides a modified config file for the default Shuttle-A payload container so that it can be used with the XR-5 Vanguard.  This excellent ship is available at Doug's Orbiter Page:
http://www.alteaaerospace.com/
The new config file allows you to load these containers via the built-in payload manager that comes with the XR-5.
Now you can use the XR-5 to resupply all your Shuttle-A's !
Please see the enclosed Readme file for further documentation. This is my first addon, so please report any bugs or problems.
Happy Orbiting
