Pratt & Whitney X-1800 (oznaczenie wojskowe Pratt & Whitney H-2600) – 24-cylindrowy, chłodzony cieczą silnik płaski o układzie "H" projektowany w zakładach Pratt & Whitney na początku lat 40. Przy pojemności ponad 40l miał osiągać moc pomiędzy 1850 a 2200 KM i stanowić jednostkę napędową takich samolotów jak Vultee XP-54 Swoose Goose, Curtiss-Wright XP-55 Ascender, Northrop XP-56 Black Bullet czy Lockheed XP-49.
Rozpoczęcie produkcji seryjnej tego silnika planowano na 1942, ale już 1940 w powodu wielu problemów konstrukcyjnych zaprzestano nad nim prac rozwojowych, a zakłady Pratt & Whitney przeszły w całości na produkcję silników gwiazdowych.

The flag of Navassa Island is simply the United States flag. It does not have a "local" flag or "unofficial" flag; it is an uninhabited island. The version with a profile view was based on Flags of the World and as a fictional design has no status warranting a place on any Wiki. It was made up by a random person with no connection to the island, it has never flown on the island, and it has never received any sort of recognition or validation by any authority. The person quoted on that page has no authority to bestow a flag, "unofficial" or otherwise, on the island.
