Pratt & Whitney R-2800 Double Wasp
The Pratt & Whitney R-2800 Double Wasp is a two-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of 2,800 in³ (46 L), and is part of the long-lived Wasp family.
The R-2800 is considered one of the premier radial piston engines ever designed and is notable for its widespread use in many important American aircraft during and after World War II. During the war years, Pratt & Whitney continued to develop new ideas to upgrade this already powerful workhorse, most notably water injection to give emergency power in combat.

“When the Church of Jesus
Shuts its outer door,
Lest the roar of traffic
Drown the voice of prayer:
May our prayers, Lord, make us
Ten times more aware
That the world we banish
Is our Christian care.”
—Frederick Pratt Green (b. 1903)
“On the death of a friend, we should consider that the fates through confidence have devolved on us the task of a double living, that we have henceforth to fulfill the promise of our friend’s life also, in our own, to the world.”
—Henry David Thoreau (1817–1862)
“Why should the generations overlap one another at all? Why cannot we be buried as eggs in neat little cells with ten or twenty thousand pounds each wrapped round us in Bank of England notes, and wake up, as the Sphinx wasp does, to find that its papa and mamma have not only left ample provision at its elbow but have been eaten by sparrows some weeks before we began to live consciously on our own accounts?”
—Samuel Butler (1835–1902)
