Development of an Improved Ballistic Acceptance Test for High Hard Armor Steel Plate - MIL-A-46100
Abstract
This report is one of three reports generated as a subtask under the project entitled 'Development of Improved High Hard Armor Steel MIL-A-46100)' funded by the PM, Survivability (TACOM). This report investigates ballistic acceptance tests for MIL-A-46100 plate. Ballistic test results for MIL-A-46100 armor plate with the 20mm M602 projectile show a high level of scatter in V50 values. The V50 is used as the criterion for acceptance/ rejection of MIL-A- 46100 armor plate. Furthermore, the M602 projectile produces a shatter gap phenomenon when tested-verses high hardness plate near the 1.1 inch thickness. The shatter gap results in two V50 values with a spread of approximately 180 - 200 ft./sec.. Reasons for the high failure rate of 20% for MIL-A-46100 plate can, in part, be attributed to a combination of shatter gap phenomenon and scatter in V50 measurements. ARL/MD heats of MIL-A-46100 armor plate were processed and tested with the 20mm M602 projectile and a 1/2 scale 30mm APDS tungsten projectile. Results of ballistic testing show that the 1/2 scale 30mm APDS projectile exhibits minimal scatter in V50 values with no shatter gap and therefore is considered to be a superior round for testing and qualifying MIL-A- 46100 steel armor.
