NOTES: (This section contains information of a general nature which may be helpful, but is not mandatory)

Changes from previous issue: Marginal notations are not used in this revision to identify changes with respect to the previous issue due to the extent of the changes.

Intended use: This battery is intended for use in the Nett Warrior and Soldier Warrior systems.

Please note that this battery must be electromagnetically compatible with these systems. Such compatibility is no guarantee of similar compatibility with any other system. Electromagnetic compatibility with any other system needs to be evaluated separately, and in the case of failure, either that system will need to adjust to this battery or another battery will need to be developed.

Electromagnetic interference testing: Verification requirements include electromagnetic interference tests of MIL-STD-461 with the battery connected to the system. Battery vendors will need to coordinate with the Project Manager, Soldier Warrior (SWAR), in order to arrange to have their products evaluated in the system. Their address is: Project Manager, Soldier Warrior, ATTN: SFAE-SDR-SWAR, 10125 Kingman Road, Building 317, Fort Belvoir, VA 22060-5820.

Bullet penetration: The Department of Defense requires for bullet penetration testing to have Government safety personnel present to witness the testing. Potential offerors are cautioned to review solicitations for such requirements. Should this be required, battery vendors should contact Project Manager, Soldier Warrior (SWAR), in order to arrange to have their products tested. Their address is: Project Manager, Soldier Warrior, ATTN: SFAE-SDR-SWAR, 10125 Kingman Road, Building 317, Fort Belvoir, VA 22060-5820.

Below are some recommended safety precautions for bullet penetration testing:

Any conducted testing should have appropriate fire extinguisher, 5 gallon bucket of water or sand, safety glasses for personnel, oven type mitts when near test articles under test, appropriate ventilation or plan in case of thermal race conditions, and appropriate range safety personnel and procedures that are reviewed with all present in advance of the tests.

Additionally fire log tongs or another device that is 32 inches or longer shall be present to move an “active” system under test should it be required. Personnel performing weapons fire should be qualified on or in the direct presence of weapon qualified personnel. Range safety measures should be defined in advance and briefed to ALL personnel present during tests.

Configuration Manager: The configuration manager for this battery is Project Manager, Soldier Warrior (SWAR). Their address is: Project Manager, Soldier Warrior, ATTN: SFAE-SDR- SWAR, 10125 Kingman Road, Building 317, Fort Belvoir, VA 22060-5820.

Other data: Navy safety tests of NAVSEA S9310-AQ-SAF-010 and NAVSEA SG270-BV-SAF- 010 are required for this battery during first article testing. The test data provided from the testing will be used to evaluate applications for specific using devices and Navy platforms.

Devices using this battery will require US Navy Safety Approval prior to use by Department of Navy users unless such approval has already been granted. Please consult with NAVSEA Instruction 9310.1 for further information.
