These annual reports provide a snapshot of the mishap trends across our Navy and Marine Corps for the fiscal years listed. Mishaps, many of them preventable, transcend both time and warfare communities. These reports provide an opportunity to study the data and lessons learned, to look for ways in which everyone can adjust their own mishap prevention efforts to go about their daily routine both on- and off-duty. There are many areas where the Navy and Marine Corps teams can work together to identify commonalities in mishaps and share information and successful mitigation efforts that benefit everyone.
