Movement rotation

Hey there, I am currently working on a top down space game. I have a space ship which I can move around fine. However what I am missing right now is a Rotation, what I want to achieve is that when facing upwards and moving f.e. to the right the ship already moves to the right and at the same time turns around in order to face to the right side. I don't whant that the ship instantly Points to the right direction.

The only code I have so far is this: (As you can see the Basic movement is there but no rotation)

 var speed : int;
 
 
 function Update () 
 { 
     //Move Player
     var transV : float = Input.GetAxis("Vertical") * speed * Time.deltaTime;
     var transH : float = Input.GetAxis("Horizontal") * speed * Time.deltaTime;
 
     transform.position = new Vector3(transform.position.x+transH, transform.position.y+transV);
