Martin XB-48

---

The Martin XB-48 was designed to meet an Army Air Force request for a jet bomber made in Spring of 1944. Three other bomber development projects (the North American XB-45, the Consolidated XB-46, and the Boeing XB-47) were also initiated to meet this AAF request, but none of them were developed in time to serve during WWII.
