Technical Committee in April 1951. At time of its development the E77 represented one-sixth of all U.S. biological munitions efforts. The E77 was designated a "strategic weapon" and readied for deployment but was never used in warfare as subsequent developments in munitions supplanted the E77,

Further testing in 1958 showed that when 683: 331: 445: 850: 46:, Japan employed thousands of incendiary and antipersonnel weapons via unmanned balloon, using some 9,300 of these devices, releasing them into the high altitude 865: 845: 62:
Development of the E77 balloon bomb began in 1950. The design of the E77 was based on the design for the World War II Japanese bomb and approved by the

At least three separate sets of tests were conducted with the E77 balloon bomb. From October to December 1954 41 E77s were launched at

The E77 used feathers as a vector to disseminate anti-crop agents from a hydrogen-filled balloon and was first developed in 1950. 317: 840: 303: 285: 217: 183: 132: 738: 260: 410: 209: 175: 460: 415: 860: 814: 728: 142: 137: 88: 231: 120: 571: 470: 779: 708: 642: 622: 819: 546: 123:
