Search Defense Parts by National Stock Number

Search our defense NSN parts database to find the exact part you need within seconds. We make it easy to find the correct part for application on vehicles and machines within the defense industries. The defense industry has different standards to those in the aviation industry, therefore certain NSNs are more popular within the defense industry.


National Stock Numbers, or NSNs, are 13 digit serial numbers assigned to all components sourced and procured in the federal supply chain. Defense Parts can range from aircraft bearings to fuselage components. The components must adhere to strict military standards (MS) that take into account the hostile conditions in which the components must function in. For example military bearings must be able to withstand the high friction levels of a helicopter rotor drive.


At ASAP Distribution, owned and operated by ASAP Semiconductor, we stock over 2 billions NSNs including those used in the defense industry. We encourage you to use our defense parts database to source your part in no time at all. All of our parts undergo numerous phases of quality control that verify military standards. We are the only independent distributor with a No China Sourcing policy. We only source from manufacturers we trust. In return, our customers trust us to solve all their parts procurement problems.
