NASA Boeing 377 Stratocruiser Guppy
A repaint of the payware a2a Simulations Boeing WoS B377 Pregnant Guppy. Text…
Boeing 377 Stratocruiser repaint brings Sean Doran’s classic prototype-era styling to the A2A Simulations payware airliner, delivering crisp exterior textures that suit the iconic four‑engine prop’s streamlined lines and period details. Built for Microsoft Flight Simulator X, it requires the original B-377 model and adds an authentic vintage finish to the virtual cockpit experience.
This repaint showcases a meticulously crafted livery designed by Sean Doran for the payware Boeing 377 Stratocruiser produced by A2A Simulations. It provides an authentic exterior finish that replicates the classic styling of this legendary four-engine propeller airliner. These textures function specifically in Microsoft Flight Simulator X and require the original payware model, which is not included.
The actual Boeing 377 Stratocruiser traces its lineage to post-WWII advances in long-range commercial aviation. With its robust radial engines and pressurized cabin, it redefined transoceanic travel during the late 1940s. Pan American Airways famously introduced the type, placing a significant order in November 1945. However, certification hurdles postponed its service entry until 1949. In time, some Stratocruisers were retrofitted with upgraded interiors and eventually transformed by Aero Spacelines into specialized cargo variants like the Pregnant Guppy, underscoring the airframe’s adaptability.

description=On 28 November 1945 Pan American ordered 20 Stratocruisers. This made PAA the first airline to put the new Boeing Stratocruiser into service. It was hoped to have the B-377s in service by the end of 1946 but a long drawn out certification process held up service entry until 1949. Boeing B-377 NX1024V was the third Stratocruiser prototype, its first flight took place on October 7th, 1948. Although it was named Clipper America it was actually the 2nd Pan American B-377 to be called Clipper America. The first Clipper America was the second Stratocruiser prototype, NX1023V and was later renamed Clipper Golden Gate. NX1024V was delivered to Pan American as Clipper Bald Eagle N1024V on June 12th, 1949. It was later refitted as a Super Stratocruiser, renamed as Clipper Cathay and used for the Pacific routes. It was eventually sold to Aero Spacelines and was converted to a Pregnant Guppy (N1024V).
