The Boeing PB-1 was the U.S. Navy designation for the B-17 Flying Fortress. Forty Eight B-17Gs were acquired by the navy during 1945 to be used to carry airborne early warning radar. In order to give more warning against Japanese attacks, the US Navy was posting radar-equipped picket ships ahead of the main fleet, but those ships were themselves suffering unacceptably high losses. The navy decided to replace these vulnerable ships with aircraft carrying APS-20E search radar. A number of different aircraft were considered for the role. The B-17 was chosen because it could carry the radar and retain its guns, considered essential if the aircraft was to survive over the Sea of Japan. |
PB-1 war der U.S. Navy Bezeichnung für die B-17 Flying Fortress. 84 B-17Gs wurden von der Marine im Jahre 1945 erworben, um verwendet werden, um ein luftgestütztes Radar zu tragen. Die Navy verwendete mit Radar ausgerüstete Schiffe um eine Vorwarnung vor japanischen Angriffen zu haben, doch diese Schiffe erlitten grosse Verluste. Die Marine beschloss, diese gefährdeten Schiffe durch Flugzeuge mit APS-20E Suchradar zu ersetzen. Eine Reihe von verschiedenen Flugzeuge wurden für die Rolle betestet. Die B-17 wurde gewählt, weil sie das Radar tragen konnte und dennoch mit Maschinengewehren bewaffnet war, was als unerlässlich über dem Japanischen Meer angesehen wurde. |

Einsatzgeschichte |
||||||||||||||||||||||||||||||||||||||||||||||||
The war ended before the radar equipped aircraft could enter service. Navy Squadron VPB-101 received its first PB-1 (without radar) in September 1945, the month after Japan had surrendered, and its first radar equipped PB-1W in January 1946 After the war the PB-1W was used to mount patrols between Newfoundland and Iceland and around the Azores, guarding against a possible Soviet attack. Other aircraft were used for meteorological research and on hurricane patrols. The PB-1W remained in service after the majority of other American B-17s had been scrapped. |

Der Krieg endete bevor dem die Radar ausgerüsteten Flugzeuge Dienst treten konnten. Die Navy Squadron VPB-101 erhielt im September 1945, dem Monat nach der Kapitulation Japans, die ersten PB-1 (ohne Radar), im Januar 1946 erhielt die Staffel die erste Radar ausgerüstet PB-1W. Nach dem Krieg wurde die PB-1W für Patrouillen zwischen Neufundland und Island und rund um die Azoren verwendet, zum Schutz vor einen möglichen Angriff der Sowjetunion. Andere Flugzeuge wurden für die meteorologische Forschung und Hurrikan-Patrouillen eingesetzt. Die PB-1W blieb im Dienst, nachdem die meisten anderen amerikanischen B-17 verschrottet waren. |
