Boeing YB-40 Flying Fortress
The Boeing YB-40 Flying Fortress was a modification of the United States B-17 Flying Fortress bomber aircraft converted to act as a heavily-armed escort for other bombers during World War II. At the time of its development long-range fighter aircraft such as the P-51 Mustang were just entering quantity production and thus were not yet available to accompany bombers all the way from England to Germany and back.
Il Boeing YB-40 Flying Fortress era un quadrimotore ottenuto modificando il bombardiere statunitense B-17 Flying Fortress, convertendolo in un aereo pesantemente armato da utilizzare come scorta degli altri bombardieri durante l'ultimo periodo della seconda guerra mondiale.1
Made by Vega Aircraft Corporation.
It is the successor of the Boeing B-17 Flying Fortress .
