About UASA

Ukraine Siren Alerts (UASA) is an organization committed to the early detection and warning of missile and drone attacks on Ukraine. Created by Bernard Moerdler, a passionate Israeli student inspired by his Ukrainian girlfriend, Bernard immediately understood the importance of an early
detection program.

Created at the beginning of the war in Ukraine, UASA is based on Israel's Red Color system which automatically alerts users of incoming missiles and drones, enabling civilians to take proper precautions and seek immediate shelter. Originally established on Twitter, UASA has now spread to various social media platforms and functions via SMS notifications, guaranteeing that individuals with or without cellular service may still receive alerts.
