Description
This is a bar-type fuze which differs from fuze AN-M166 in that the nominal MinSAT is 2,000 feet, and the transverse dipoles (bars) have been strengthened so that they can be used to screw the fuze into the bomb without a wrench, if necessary (use of a wrench is desirable, however, since the fuze must be tight in the bomb). The sensitivity, as shipped, is equal to one-half that of fuze AN-M166, but the sensitivity of the M166E1 can be set to be equal to that of AN-M166. The sensitivity is adjusted by removing a clearly labeled, knurled thumbscrew which projects from the fuze housing. The thumbscrew is left in place to reduce the sensitivity for target conditions so that a low burst height will result in relatively greater damage. Except for the thumbscrew, the external contours of the M166E1 are identical with the AN-M166.
