Excellent question! Filtering specifically for military aircraft on Flightradar24 requires a bit of know-how, as there isn’t a simple “Military Only” button. This is primarily because most military flights do not publicly broadcast their position.
Here’s a breakdown of how to find them, from easiest to most advanced:
This is the most effective built-in tool. Flightradar24 uses the ICAO aircraft type designator “U” to categorize many military aircraft.
On the Web/Desktop: Look for the filter icon (looks like a funnel) in the top-right corner. Click it, then under “Aircraft type,” type U (capital U) and select it. This will show only aircraft with a military type code.
On the Mobile App: Tap the filter icon (funnel) at the top of the screen. Go to “Aircraft Type” and type U in the search bar. Select the “U” filter that appears.
What this shows: Aircraft like tankers (KC-135, KC-10, A330 MRTT), transports (C-17, C-130, A400M), patrol aircraft (P-8 Poseidon, E-3 AWACS), and some trainers. It often will NOT show fighter jets, bombers, or stealth aircraft as they typically do not broadcast public ADS-B signals.
Military aircraft often use identifiable patterns: Callsigns: Look for calls
