 An ambitious operation to use the Tiny Tim against German V-1 sites as part of Operation Crossbow, code-named Project Danny, was planned but cancelled before the squadrons assigned could be deployed to Europe.Common Tiny Tim delivery aircraft during World War II included the PBJ-1 Mitchell, F4U Corsair, F6F Hellcat, TBM Avenger, and the SB2C Helldiver.After World War II, the United States Navy's rocket laboratory at Inyokern, California developed an even larger version of the Tiny Tim, called "Richard", which was 14 inches in diameter and one of the largest air-to-surface unguided rocket ever developed for the US military.
