The usage of PEMs in weapon systems subject to long term dormant storage (e.g., missiles, laser guided bombs, torpedoes, etc.) is the subject of a great amount of current controversy. Caution should be used until additional information becomes available.
- Hard data to support use of PEMs in long term (i.e., 15 to 20 years) dormant storage is lacking.
- Accelerated life test data has not been correlated to PEM long term storage risks.
