4.4.2.1.11 Shock.
4.4.2.1.11.1 Design Shock. The gun system shall be subjected to the basic
design shock test of MIL-STD-810, Method 516.2, Procedure I, Figure 516.2-2,
amplitude, duration c, for three shocks in each direction along the gun's three
mutually perpendicular axes, for a total of 18 shocks. After this test, the gun
system shall cycle dummy ammunition in two 1-second bursts. The gun system shall
meet the requirements of 3.2.1.3 and 3.2.5.11,1.
4.4.2.1.11.2 High impact. The gun system shall be subjected to the high
impact test of MIL-S=901, Grade B. The gun system shall meet the requiremnts of
3.2.5.11.2.
4.4.2.2 Recoil force. A separate test is not required. Sufficient data
shall be accumulated during other firing tests to determine the gun recoil loads.
The data shall be examined for compliance with 3.2.1.7.
4.4.2.3 Muzzle blast pressure. A separate test is not required. Sufficient
data shall be accumulated during other firing tests to determine the gun muzzle
blast pressure pattern. The data shall be examined for compliance with 3.2.1.8.
4.4.2.4 Electronmagnetic compatibility tests. The gun system shall be
tested in accordance with the interference Control plan specified herein and MIL-
STD-462 to determine if the system meets the requirements of 3.3.2.
4.4.2.5 Reliability. Data taken during the tests of 4.4.2.6 shall be
analyzed to determine if the gun system meets the requirements of 3.2.3.
4.4.2.6 Durability. One gun system shall be subjected to a 30,000 round
firing test during which nonmaintenance other than scheduled maintenance shall be
performed, and no unscheduled parts replacement shall be made. During the test a
minimum of three complements shall each be fired in a continuous burst. The
remaining rounds shall be fired in accordance with the burst firing schedule of
3.2.1.5. The test data shall be analyzed for compliance with the requirements of
3.2.1.3, 3.2.3, and 3.2.3.1. Bore erosion criteria data will be collected and
developed during this test.
4.4.2.7 Maintainability. The maintainability requirements of 3.2.4 shall
be demonstrated in accordance with MIL-STD-471, Method 9.
4.4.2.8 Safety. A separate test is not required. Data taken during other-
firing tests shall be analyzed to determine if the gun system meets the require
ments of 3.3.5.1 through 3.3.5.6.
4.4.2.9 Extended burst firing. The gun system shall be loaded with 300
rounds of TP-T ammunition. The gun system shall be fired in a single burst until
the ammunition is exhausted. The gun system and test data shall be examined for
compliance with 3.2.1.2, 3.2.1.3, 3.2.1.4, and 3.2.1.6.
