How many missiles does a fighter jet hold?

The Air Force, U.S. Navy and Raytheon Technologies have successfully test-fired an AIM-9X Block I missile at a target in the air from an F-35A aircraft. The F-35 can carry up to two AIM-9X missiles on its wings and four AIM-120 AMRAAM missiles internally.

Do all planes have winglets?

Several airliners use them. The Airbus A319 and A320 have very small upper and lower winglets. The longer-range twin-engine A330 and four-engine A340 have conventional winglets, as do Boeing 747-400s.

Why don’t modern fighter jets have engines on the wings?

Fighters need to have small moments of inertia, especially in roll, so they cannot afford to put engines on the wings. Even the Me-262 was initially planned with fuselage-mounted engines, that’s why it had this peculiar triangular fuselage cross section.

Why do planes have such a lightweight structure?

There’s also a weight advantage. The wings lift the plane, the engines are a major weight component of the aircraft. So if the weight is where the lift is being produced you don’t need to reinforce the structure to carry the forces around. Hence lighter structure.

Why do planes have engines mounted on the wing?

Only when the engines grew in diameter during development they had to be placed on the wing. Pros of rear-mounted / fuselage-mounted engines: The wing is clean, having low drag and optimum conditions for lift creation. The engines are easy to access (if mounted at the rear fuselage.

What are the disadvantages of rear-mounted / fuselage-mounted engines?

Cons of rear-mounted / fuselage-mounted engines: No bending relief for the wing; heavier wing spar needed. No help in flutter supression (a mass ahead of the elastic line helps). Possible interference with wing wake at high angle of attack. Forces the tail to be a T-tail configuration.
