377M

In the early 1960s, the Israeli Air Force wished to upgrade to the C-130 Hercules which could lift larger payloads, but it was expensive and sales were embargoed by the United States. Instead, Israeli Aircraft Industries at Ben Gurion International Airport offered to modify Boeing 377 Stratocruisers it had with a stronger cabin floor which could handle cargo, plus a C-97 military Statocruiser tail section, which included a clam shell cargo door. These were dubbed Anak (or Giant in Hebrew) and served starting in 1964. Three of these were modified by the use of a swing tail section, similar to the Canadair CL44D-4 airliner. Two others served as aerial tankers with underwing hosereel refuelling pods. Two others were ELINT-platforms for electronic reconnaissance, surveillance and ECM-missions (ECM-Electronic Counter Measures). These were later joined by four KC-97G's with the flying boom system.
