Unusual aircraft and test vehicles launched from carriers

What unusual things besides a P-47 have been launched from aircraft carriers?

C-130s, dedicated catapult test vehicles, and even expendable cars have all featured in carrier launch trials or stories.

Famous aircraft trials depended on less glamorous machinery that could test a launch system safely. Dedicated dead-load vehicles reproduced weight and resistance without risking an operational aircraft. Old cars were reportedly offered for catapult tests when they were already destined for disposal. These trials mixed careful flight-deck engineering with conspicuous improvisation.
