Look at the front of a Rafale, a Eurofighter Typhoon, a Gripen or a Chinese J-20 and you will see a small pair of wings mounted high on the nose, ahead of the main wing. They are called canards, and they divide the fighter world in two. Europe and China build their best fighters around them; the United States, on its stealthiest jets, refuses to fit them at all. The disagreement is not fashion. It is physics.
A canard is simply a small foreplane placed ahead of the aircraft’s centre of gravity. What it does there turns out to be surprisingly powerful — and surprisingly awkward for a stealth designer.

What a Canard Actually Does
A conventional fighter carries its horizontal control surface at the tail, where the tailplane usually pushes down to keep the nose up — a small but constant penalty called trim drag. A canard sits at the other end and does the opposite: it can be made to lift, sharing the load with the main wing instead of fighting it. On a delta, a canard also sheds a powerful vortex that sweeps back over the wing, re-energising the airflow and delaying the stall to very high angles of attack.
A detailed look at why the delta-canard layout became so popular in European fighters.
Why the Delta Loves a Canard
The pure delta wing is a superb supersonic shape: low drag, big internal volume, structurally simple. Its weakness is low-speed handling and a tendency to bleed energy in tight turns. Bolt a canard onto the nose and many of those vices soften — the foreplane restores pitch authority, sharpens the turn, and lets the designer relax the aircraft into deliberate instability that a fly-by-wire computer then tames. It is no accident that the Viggen, Rafale, Typhoon, Gripen and J-20 are all canard deltas.

Why Stealth Refuses Them
So why do the F-22, F-35 and B-21 wear none? Because a canard is, to a radar, a bright moving reflector hung right at the front of the aircraft — the very aspect a fighter most needs to hide. Extra edges, extra gaps and extra moving surfaces all add returns exactly where low observability matters most.
The F-47 Puts Them Back
Which makes the newest twist so revealing. Boeing’s F-47, America’s next fighter, reportedly wears canards — a break from two decades of stealth orthodoxy. Read one way, it says the Air Force decided agility and range were worth a measured hit to frontal stealth; read another, it hints that radar-absorbing materials and clever shaping have advanced enough to blunt the old penalty. Either way, the little wings up front are once again telling you what an aircraft was really designed to do.

Related Questions
What are canards on a fighter jet?
Canards are small foreplanes — a second, smaller pair of wings — mounted on the nose ahead of the main wing and the aircraft’s centre of gravity. They provide pitch control, generate extra lift, and energise the airflow over the main wing. Fighters such as the Eurofighter Typhoon, Dassault Rafale, Saab Gripen and Chinese J-20 are built around them.
What do canards do for an aircraft?
A canard placed ahead of the centre of gravity gives strong pitch authority, adds lift, and sharpens turning performance. It works especially well on tailless delta wings, restoring the low-speed handling a pure delta lacks. Combined with fly-by-wire controls, canards let designers make an aircraft deliberately unstable — and therefore more agile — while the computer keeps it flyable.
Which fighter jets have canards?
Canard deltas include the Saab 37 Viggen, the Dassault Rafale, the Eurofighter Typhoon, the Saab Gripen and China’s Chengdu J-20. European and Chinese designers have favoured the layout for its agility and lift, pairing a small foreplane with a tailless or near-tailless delta wing.
Why don’t stealth fighters like the F-22 and F-35 have canards?
Because a canard is, to radar, a bright moving reflector placed right at the front of the aircraft — the aspect a stealth fighter most needs to hide. Its extra edges, gaps and moving surfaces add radar returns exactly where low observability matters most. That is why the F-22 Raptor, F-35 and B-21 wear no canards at all.
What is a canard delta?
A canard delta combines a triangular delta main wing with a canard foreplane on the nose. The delta gives low drag, large internal volume and a simple, strong structure ideal for supersonic flight, while the canard fixes the delta’s weak low-speed handling and energy bleed in tight turns. The Viggen, Rafale, Typhoon, Gripen and J-20 all use this layout.
Are canards good or bad for a fighter jet?
It is a trade-off. Canards add agility, lift and pitch control, which is why many European fighters use them — but they also add complexity and radar signature, making frontal-aspect stealth harder. China’s J-20 is the notable exception among stealth fighters: it keeps canards, accepting some signature penalty in exchange for aerodynamic performance.
Do canards make a plane more maneuverable?
Generally yes. By adding a control surface ahead of the centre of gravity, canards give quick, powerful pitch response and let a design be tuned for relaxed stability, which increases agility. They also help delay airflow separation over the main wing at high angles of attack. The downside is added structural and aerodynamic complexity, and a larger radar signature.
