Military analysts attributed the detection gap to the use of RM-48U modified S-400 missiles, which are more difficult to track than standard ballistics, noting a similar undetected strike in Mykolaiv on Oct. 2. Presidential adviser Beskrestnov stated that partners' intelligence services have missed such launches in the past due to technical nuances. These attacks followed a separate Shahed drone strike on a 25 story apartment building in the Darnytskyi district that killed 2 civilians and injured 9.
