Send GameObject to another script

Hello!
I have 3 scripts:
AAMLauncher.cs - creates air-to-air missiles (AAM), attached to Player
AimingCamera.cs - find enemy targets, attached to aiming camera and AAM prefab
HomingMissile.cs - homing AAM to the enemy target, , attached to AAM prefab
How can I send GameObject (enemy target) from AimingCamera.cs to HomingMissile.cs?

AAMLauncher.cs:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class AAMLauncher : MonoBehaviour
4. {
5.     public Rigidbody AAM;
6.     public Transform AAMPoint;
7.     public int AAMSpeed = 100;
8.     public float LaunchDelay = 2f;
9.     public float Damage = 10f;
10.     public string[] targetTags = { "Ground", "Building", "Soldier", "Tank", "APC", "NSTV", "Helicopter" };
11.     private float CurDelay = 0f;
12.  
13.     public void AAMLaunch()
14.     {
15.         if (CurDelay <= 0f)
16.         {
17.             CurDelay = LaunchDelay;
18.             Rigidbody AAMInstance = Instantiate(AAM, AAMPoint.transform.position, AAMPoint.transform.rotation) as Rigidbody;
19.         }
20.     }
21.  
22.     void FixedUpdate()
23.     {
24.         if (Input.GetMouseButton(0)) AAMLaunch();
25.         if (CurDelay > 0f) CurDelay -= Time.deltaTime;
26.     }
27. }

AimingCamera.cs:

Code (CSharp):

1. using UnityEngine;
2. public class AimingCamera : MonoBehaviour
3. {
4.     public int AngularVelocity = 180;
5.     private float X, Y, Z;
6.     private float eulerX = 0, eulerY = 0;
7.     private Vector3 AimingPoint;
8.     public GameObject AimTarget;
9.     void Update()
10.     {
11.         X = Input.GetAxis("Mouse X") * AngularVelocity * Time.deltaTime;
12.         Y = -Input.GetAxis("Mouse Y") * AngularVelocity * Time.deltaTime;
13.         eulerX = (transform.rotation.eulerAngles.x + Y) % 360;
14.         eulerY = (transform.rotation.eulerAngles.y + X) % 360;
15.         transform.rotation = Quaternion.Euler(eulerX, eulerY, 0);
16.         RaycastHit hit;
17.         AimingPoint = new Vector3(X, Y, Z);
18.         if (Physics.Raycast(AimingPoint, transform.rotation * Vector3.forward, out hit))
19.         {
20.             AimTarget = hit.collider.gameObject;
21.         }
22.     }
23. }

HomingMissile.cs:

Code (CSharp):

1. using UnityEngine;
2. public class HomingMissile : MonoBehaviour
3. {
4.     public GameObject AimTarget;
5.     public GameObject AAMExplosionPrefab;
6.     public float AAMSpeed = 20;
7.     public float AAMTurnSpeed = 90;
8.     public float AAMExplosionTime = 20;
9.     private Transform _thisTransform;
10.     public void Awake()
11.     {
12.         _thisTransform = transform;
13.     }
14.     void Update()
15.     {
16.         AAMExplosionTime -= Time.deltaTime;
17.         if (AAMExplosionTime <= 0)
18.         {
19.             Explode();
20.             return;
21.         }
22.         Vector3 movement = _thisTransform.forward * AAMSpeed * Time.deltaTime;
23.         if (AimTarget != null)
24.         {
25.             Vector3 direction = AimTarget.transform.position - _thisTransform.position;
26.             float maxAngle = AAMTurnSpeed * Time.deltaTime;
27.             float angle = Vector3.Angle(_thisTransform.forward, direction);
28.             if (angle <= maxAngle) _thisTransform.forward = direction.normalized;
29.             else _thisTransform.forward = Vector3.Slerp(_thisTransform.forward, direction.normalized, maxAngle / angle);
30.             float distanceToTarget = direction.magnitude;
31.             if (distanceToTarget < movement.magnitude)
32.             {
33.                 Explode();
34.                 return;
35.             }
36.         }
37.         _thisTransform.position += movement;
38.     }
39.     public void Explode()
40.     {
41.         if (AAMExplosionPrefab != null) Instantiate(AAMExplosionPrefab, _thisTransform.position, _thisTransform.rotation);
42.         Destroy(gameObject);
43.     }
44.     public void OnCollisionEnter()
45.     {
46.         Explode();
47.     }
48. }

AAM (Clone) inspector:

 

Getting the script in start with:
hm = GetComponent<HomingMissile>();

Save it in a private variable and use and when you find your target:

hm.AimTarget = AimTarget:
