Example The vehicle must be capable of accepting, supporting, and mounting a MK19, 40mm automatic grenade launcher. Transportability The inherent capability of an item or system to be moved efficiently over railways, highways, waterways, oceans, or airways either by carrier, towing, or self-propulsion.
Examples The vehicle must be capable of being rigged for air drop by the using unit without the use of special tools, within X minutes. The M939A2 5-ton truck shall be capable of being slingloaded beneath the CH-47D or the CH-53E helicopters using integral vehicle lift points . Interoperability The ability of systems, units, or forces to provide services to, and accept services from, other systems, units, or forces and to use the services so exchanged to enable them to operate effectively together.
Example The aircraft’s turreted cannon will mount the XM788 gun system used by the AV-8A Harrier aircraft to provide NATO interoperability among the Armament Development Enfield (ADEN) and Direction D’Etudes et Fabrication D’Armament (DEFA) gun systems currently in use. Reliability (a) The duration or probability of failure-free performance under stated conditions. (b) The probability that an item can perform its intended function for a specified interval under stated conditions. (For non- redundant items this is equivalent to definition (a).
For redundant items this is equivalent to mission reliability.) Example The mean time between failure (MTBF) of the signature-suppressed generator sets (15/30/60 KW) shall not be less than 40 hours. 6-9
