At present there are four modifications of the T50 75-mm HE shell, three of which, the T50E2, the T50E8, and the T50E9, have been tested earlier in the course of development, and one, the T50E10, which has just recently been designed. The T50E2, adopted as standard when filled with TNT and designated the M334 in January 1956, and the T50E9 are identical in design except that the former uses a gildingmetal rotating band and the latter employs two sintered- iron rotating bands. Unlike conventional shell, which have either a square or boattail base, the T50E2 and T50E9 have hemispherical bases to which are welded covers that follow the contour of the base proper. The T50E8 has a square base and a gildingmetal band identical with that used on the T50E2. The T50E10, which also has a gildingmetal band, differs from the others only in that it has a truncated conical base. Each of these shell has a deep cavity and contains approximately 1.42 lb of explosive and a 0.25lb supplementary explosive charge, which is removed when a proximity fuze is used. All of the shell in the T50 series have relatively thin walls to provide for maximum fragmentation.
