Like the C-97, the 377 was developed towards the end of World War II by adapting an enlarged upper fuselage onto the lower fuselage and wings, which were essentially the same as those of the B-50 Superfortress, the high-performance evolution of the B-29 Superfortress bomber. The 377 was larger and longer-ranged than the Lockheed Constellation and Douglas DC-6, with nonstop transatlantic range eastbound, but the P&W R-4360 Wasp Major engines proved uneconomical, with production ending in 1950. The "inverted-figure-8" double-deck fuselage design provided 6,600 ft³ (187 m³) of interior space where the lower deck had a smaller diameter than the upper deck. It offered seating for over 100 passengers, or sleeping berths for up to 28 berthed and five seated passengers. It first flew on July 8, 1947. It had the speed and range to span ocean routes, enabling flying from New York to Hawaii in less than 24 hours. Pressurization allowed sea-level cabin pressure at 15,500 ft (4,700 m) altitude. At 25,000 ft (7,600 m), passengers enjoyed a "cabin altitude" of only 5,500 ft (1,700 m).

Despite a service record remembered for one or two early disasters arising from a propeller design fitted to the Stratocruiser in its earlier years, Boeing's remarkable airliner was one of the most capable of post-war propeller-driven transports, and certainly among the most luxurious. Only 55 were built as airliners, joined eventually by the reconditioned prototype to make a total of 56. Another 60 of this general design, with significant engineering differences, were built as C-97 military transports, but the majority were built as KC-97 tankers, with many more military successors to follow. The jet-powered Boeing 707 would regain Boeing's dominance in the civil airliner market, while the KC-135 would continue to serve as a jet tanker into the twenty-first century. The lengendary Lockheed C-130 of the mid-1950s was somewhat similar in size and speed, but as it adopted turboprop power and was packaged from ground-up as a combat airlifter with tail ramp for operation from rough fields, it would become one of the most successful military aircraft of all time.
