Analyst brief

The U.S. Navy's record contains one entry: a June 2025 malfunction of an unmanned surface vessel during a tow test that caused a support boat to capsize, classed as a malfunction at severity 3. The index of 17.4 and 67.7th percentile place this record in the elevated band within the broad other category, reflecting a moderate-severity single incident rather than a volume pattern.
