How to identify military aircraft
Look for gray or camouflage paint, a national insignia like the US star-and-bar or a roundel instead of an airline logo, and a serial number on the tail. Then read the shape: twin tails usually mean a fighter, a high wing and fat body mean a transport, and a disc on top means an airborne radar.
The paint
Most military aircraft wear gray, in shades picked to blend into the sky. Helicopters and some transports wear dark green or camouflage, made to blend into the ground. Not all of them are dull, though: US Coast Guard aircraft are white with an orange-red stripe, display teams wear bright colors, and VIP jets often look like airliners, painted white and blue like Air Force One.
The markings
- National insignia. US military aircraft carry the star-and-bar: a white star in a circle with bars on each side. The UK uses a red, white and blue roundel, Canada a roundel with a red maple leaf, and Australia a roundel with a red kangaroo. On gray aircraft these are often painted in low-visibility gray or black.
- Service names. “U.S. AIR FORCE,” “NAVY,” “MARINES” or “ARMY” is often painted on the fuselage or tail.
- Serial numbers. Military aircraft carry serials instead of civil registrations. On US Air Force aircraft, the tail number usually starts with the fiscal year the aircraft was ordered. Navy and Marine aircraft use a six-digit number, and RAF serials are two letters and three numbers.
The shapes
- Two tail fins, small and fast: a fighter, like the F-15, Super Hornet, F-22 or F-35. The F-16 is the common single-fin exception.
- High wing, fat body: a transport. Four props is a C-130; four jets and a T-tail is a C-17.
- A boom under the tail: a tanker, like the KC-135 or the KC-46. Hose-and-drogue tankers carry refueling pods under the wings, and many A330 MRTTs have both pods and a boom.
- A big disc on top: an airborne radar. On a four-engine jet it’s an E-3 Sentry, also called AWACS. On a smaller twin-prop aircraft, it’s a Navy E-2 Hawkeye.
- An airliner painted gray: usually a military version of a civil jet. The P-8 Poseidon is a 737, and the KC-135 family shares the 707’s shape.
- Helicopters: two rotors is a Chinook; our twin-rotor guide covers the rest.
The callsigns
Airliners use flight numbers. Military flights use callsigns, and some are well known. REACH is the callsign of US Air Force Air Mobility Command, so a C-17 or a tanker flying as REACH followed by a number is an airlift or support flight. Air Force One is only the callsign of whichever Air Force aircraft is carrying the president. More on how callsigns work.
Pairs and formations
Fighters and helicopters usually fly in pairs or groups of four. Aircraft flying in formation often show up on a map as a single aircraft, because often only the lead is broadcasting, so two jets in the sky and one blip on the screen is normal.
Why some aren’t on the map
Many military aircraft broadcast their position like anyone else, especially transports and tankers in civilian airspace. Others don’t, or broadcast without a name. Bogey shows what is publicly broadcast, and an aircraft that won’t say who it is appears as a ghost signal. Why some planes don’t appear.
Spot respectfully
Watching military aircraft from public places is a long-standing hobby. Follow the signs around bases, stay off restricted land, and take photos from where the public is allowed to stand. Airshows are the easiest place to see military aircraft up close, and the crews are usually happy to talk about them.
