(一)美陆军研制新型迫弹引信继M734多用途迫弹引信和XM745多用途迫弹教练引信之后,美国陆军哈里·戴蒙德研究所又成功地研制了一种数字式电子时间迫弹引信。这三种引信的许多零、部件可以通用,例如他们的远解机构可以通用。目前,这三种引信组成了美军迫弹引信的家族,它们配用于60、81、120毫米和4.2英寸的迫弹上,可以取代美军现役的25种引信。 (A) US Army Develops New Type of Forcing Bombs Following the introduction of M734 multi-purpose force fuze fuses and XM745 multi-purpose force missile coaching fuses, the United States Army Harry Diamond Research Institute has successfully developed a digital electronic time bombing fuze. Many of these three fuses are zero-common parts, such as their remote solutions can be universal. At present, the three fuses form the family of the U.S. military forcing fuses. They are used on 60, 81, 120 mm and 4.2-inch bombs to replace the 25 fuses currently in active service in the United States.
