Actually I think the sub's would be able to ship the 11.1 inch ammunition. The shell is 302 kg a peice and can be shipped on the outside of the hull as per tin... It just needs to be properly waxxed n protected from the salt. The propellent charge and the silk bags can be stowed within the hull seperatly and... The graf spee can reuse her brass casings of the main charges.
Basically thegraf Spree's crew just need to set up a work shot on land to prepare the shells when they arrive.
The 2500 ton i52 can carry 300 ton cargo.. Let's approximate the u-vii at 750 ton to be able to carry 100 tons of cargo... That's 331 shells. Graf spee carried 100 rounds per gun. They fired off 414 rounds and still had 186 rounds on board. It is entirely feasible with 2 boats to resupply all ammunition to the graf spre
