25mm那个射速比起厄利孔也是相差太多。
VT确实尚未装上40mm,但最后用上的也不止127。Mk 58装给了3寸。

As development of the Mk 45 fuze progressed, it became apparent that would be desirable to utilize this fundamental design in certain of the U. S. Navy fuzes. This fuze was the first fuze small enough to be included in the U. S. Navy 3"/50 projectile. Consequently, a Mk 45 fuze was produced for the 3"/50 in about May of 1944. This fuze was delivered to the Fleet, but was never very satisfactory and its production was ultimately discontinued. A new fuze, known as the Mk 58, was designed for the 3"/50 which contained more or less the standard Mk 45 design with the addition of a wave suppression feature to permit use of this fuze low over waves. The Mk 58 fuze was delivered to the Fleet in November 1944. |
