The Martin 156, referred to in the press variously as the "Russian Clipper", "Moscow Clipper", or "Soviet Clipper" was a very large flying boat aircraft intended for trans-Pacific service. The single example of the M-156 was designed and built in response to a request from Pan American World Airways to provide a longer-range replacement for the Martin M-130.
