ZMC-2

The ZMC-2 was one of the few metal-clad airships ever built

The Aircraft Development Corporation ZMC-2 was the only successfully-operated metal-skinned airship ever built. It was built in Grosse Ile, Michigan, first flown on August 19, 1929, and flew safely for over ten years. As a sub-scale test vehicle, it was considered to be very successful, but the company that built it did not weather the Great Depression well, and by the time a successor might have been built, there was little interest in pursuing it. The US Navy classified it as a non-rigid airship.

The ZMC-2 was nicknamed the "Tin Bubble" and was also sometimes called a "tinship". It was not made of tin, but of duraluminum, an aluminum alloy. It had roughly a teardrop-shape, and had eight small stabilizer fins, four of which had rudders.

It was scrapped in 1941, reaching its planned lifetime after more than 10 years of service. Other, more conventional blimps did go on to serve in World War 2.
