A Ryan FR tűzgolyó egy vegyes teljesítményű (dugattyús és sugárhajtású) vadászrepülőgép volt, amelyet a Ryan Aeronautical tervezett az Egyesült Államok haditengerészetének a második világháború alatt. Ez volt a haditengerészet első sugárhajtóművel felszerelt repülőgépe. Csak 66 repülőgépet építettek, mielőtt Japán 1945 augusztusában megadta magát. Az FR-1 Fireball egyetlen századot szerelt fel a háború vége előtt, de nem látott harcot. A repülőgépből végül kiderült, hogy nem volt elég szerkezeti szilárdság a repülőgép-hordozók fedélzetén végzett műveletekhez, és 1947 közepén kivonták.

The Best of Both Worlds
A Ryan FR-1 tűzgolyó was a unique “mixed-power” fighter designed during World War II. At the time, early jet engines were notorious for poor acceleration and high fuel consumption at low altitudes, making carrier takeoffs and landings dangerous. Ryan’s solution was a hybrid: a conventional radial piston engine in the nose for reliability and takeoff, and a turbojet engine in the tail for high-speed combat. It was the first aircraft in U.S. Navy history to enter service with a jet engine.

A Tale of Two Engines
- The Hybrid Layout: The Fireball featured a Wright Cyclone radial in the nose driving a three-bladed propeller, while a GE J31 jet was tucked into the rear fuselage. The air intakes for the jet were flush-mounted in the leading edges of the wing roots.
- Tricycle Landing Gear: To accommodate the jet exhaust and provide better visibility for carrier landings, the FR-1 used a tricycle gear arrangement, a significant departure from the taildraggers of the era like the Corsair or Hellcat.
- Weight Distribution: The heavy radial engine in front balanced the weight of the jet engine in the rear. This allowed the aircraft to remain stable even if one engine failed or was shut down to conserve fuel during cruise.
- Structural Frailty: To keep the weight down for the two engines, the FR-1 was built quite lightly. It suffered from structural weaknesses that sometimes led to the aircraft literally “breaking its back” during hard carrier landings.
Operational History: The First Jet Kill (By Accident)
- The 1945 Entrance: The Fireball entered service with squadron VF-66 in March 1945. While it was being prepared for combat in the Pacific, the war ended before it could see action against Japanese aircraft.
- The “Unintentional” First Landing: On November 6, 1945, an FR-1 made the first-ever jet-powered carrier landing—but by accident. The piston engine failed on final approach, and the pilot was forced to start the jet engine and land under jet power alone.
- VF-1 “The Screaming Eagles”: The Fireball equipped the Navy’s first all-jet capable squadron. However, the Navy soon realized that pure-jet aircraft (like the FH Phantom) were becoming reliable enough that the complexity of maintaining two different engines was no longer worth it.
- Short-Lived Career: By mid-1947, all FR-1s were retired. They were simply outpaced by the rapid development of post-war jet technology. Today, only one complete example survives at the Planes of Fame Air Museum in Chino, California.
