Bullet firing but prefab looking in the wrong direction

Hi, beginner here,
I wanted to recreate a little tank game i played during childhood, but I have a problem with my bullets.
When fired, they follow the good trajectory ( bullet’s forward direction = blue arrow) but the prefab is facing 90° right.
I’ve model the bullet in blender, modify it’s orientation in blender then put it back in unity but it doesn’t change anything.
I’ve tried several things, the bullet spawn with the position/rotation of the turret and it follow this script :

The bullet should spawn at the position of the turret and have its own rotation (bullet’s rotation) as spawning rotation instead of being a turret rotation.

Is your bullet a Prefab? I would make it one, make sure the directions are what you want, then instantiate it using something like the example:

public class ExampleClass : MonoBehaviour
    // Instantiate a Prefab with an attached Missile script
    public Missile projectile;

    void Update()
        // Ctrl was pressed, launch a projectile
        if (Input.GetButtonDown("Fire1"))
            // Instantiate the projectile at the position and rotation of this transform
            Missile clone = Instantiate(projectile, transform.position, transform.rotation);

            // Set the missiles timeout destructor to 5
            clone.timeoutDestructor = 5;
