approval is presently appropriate for the pending contract. Bidders should not submit alternate bids
unless specifically requested to do so on the solicitation.
6.4
Description sheets and test reports.
6.4.1 Propellant description sheets. The propellant manufacturer should furnish a propellant
description sheet in accordance with MIL-STD-1171 giving a complete history of the manufacture of
each propellant lot and the results of all tests performed on it. Unless otherwise specified, copies of each
description sheet should be submitted to each of the following: Department of the Navy, Naval Surface
Warfare Center, Indian Head Division, ATTN: Gun Propelling Charge Design Agent (Code E14), 3767
Strauss Avenue, Suite 201, Indian Head, MD 20640-51505, the US Navy Major Caliber Propelling
Charge AEA, Naval Surface Warfare Center Indian Head Division Picatinny Detachment, Attn: G2,
Picatinny, NJ 07806-5000, and to the activity designated to perform the gun performance tests.
6.4.2 Gun performance test reports. The activity which performs the gun performance tests (4.6.6.2)
should furnish a complete test report, including all test, gun, projectile, and cartridge components data.
Unless otherwise specified, two (2) copies of each test report should be submitted to each of the
following: Department of the Navy, Naval Surface Warfare Center, Indian Head Division, ATTN: Gun
Propelling Charge Design Agent (Code E14), 3767 Strauss Avenue, Suite 201, Indian Head, MD 20640-
5150, and the US Navy Major Caliber Propelling Charge AEA, Naval Surface Warfare Center Indian
Head Division Picatinny Detachment, Attn: G2, Picatinny, NJ 07806-5000.
Propellant interface test. A test firing should be conducted in an instrumented mount
6.5
(instrumentation location to be as specified in NSWC, Dahlgren Division TOE Drawing 1002) on the
first article lot to verify that there is no adverse primer-propellant relationship which could cause ballistic
performance problems. The test should consist of three (3) round containing the RP and nine (9) rounds
containing the TP loaded to the AC from 4.6.6.3, for a total of twelve (12) data rounds. Three (3) TP
rounds should be conditioned, for a minimum of 72 hours, and fired at each of the following three (3)
temperatures: 20 ± 3°F, 50 ±3°F, and 120 ±3°F. In addition, a minimum of one (1) data round per
temperature of the applicable RP should be fired for comparison. The non test components (e.g., case,
primer, etc.) of the propelling charge and the propelled mass of 70 ± 0.1 pounds should be from the same
acceptable lots used for the ballistic tests (see 4.6.6.3). All rounds should be assembled in accordance
with Drawing 3208375. The analyses of the pressure-time plots will be performed by the US Navy Gun
Ammunition Propelling Charge Design Agent, Code E14, Indian Head Division, NSWC, Indian Head,
MD. Upon completion of analyses, the propelling charge design agent will advise the Naval Sea Systems
Command, Washington, D.C., in writing, relative to the results of these analyses.
6.6
Advisory
6.6.1 Relative Quickness. The average relative quickness value should be within 3.0 percent of the
reference lot when measured in a closed bomb in order to be certain of meeting the ballistic requirements
(see 4.6.8).
6.6.2 Projectile Muzzle Velocity. Charge weight is chosen to match performance of the RP but the
nominal average projectile muzzle velocity for the MK 67 propelling charge is 2,650 ft/s in a 5"/54
caliber gun system and the results of testing obtained should anticipate this for in-service performance.
6.7
Packaging
6.7.1 Packing. Packing should be at Level A. The propellant should be packed in MK 7 packing box
containers, drawing 138439, that are clean, dry and free from foreign material, conform to, and are in
accordance with the requirements of MIL-P-270 and 49 CFR 100-185. Alternate packing containers are
