Launched yep, but not from the Graf Spree Carrier, I think a test catapult was used on remodelled obselete ship, like a seaplane tender or a 'steamer'. As far as I know the Kriegmarine carrier(s) were unfunished, but possible not cut up and mat'l recycled into other weapons and armour etc until after the war, if at all, unless the Soviets towed it/them for 'reclamation and re-alocation'.
