Manufactured by Douglas Aircraft Co. of Santa Monica, California, the B-18 and its refined B-18A variant served in the Pacific, Caribbean, and Atlantic theaters before transitioning to anti-submarine patrol duty as the B-18B\/C from 1942 onward. This collection assembles the surviving primary-source factory and Air Corps technical publications for the aircraft and its powerplant — documents that defined how the Bolo was flown, serviced, and overhauled at depot level.\u003c\/p\u003e\n\u003ch3\u003eUnderstanding What Engineering and Technical Manuals Are — and Are Not\u003c\/h3\u003e\n\u003cp\u003eThese are original factory and Air Corps engineering publications — not simplified guides, not construction plans, not RC or scale-model references.
