To determine which vessel does not branch off of the aorta among the given options, we need to analyze each vessel's origin:

1. Pulmonary artery: This vessel carries deoxygenated blood from the heart to the lungs and originates from the right ventricle of the heart, not from the aorta.

2. Brachiocephalic artery: This artery branches off from the aortic arch and supplies blood to the right arm and the head and neck.

3. Left subclavian artery: This artery also branches off from the aortic arch, supplying blood to the left arm.

4. Right coronary artery: This artery arises from the aorta, specifically the ascending aorta, as it supplies blood to the right side of the heart.

Conclusion

The vessel that does not branch off of the aorta is the Pulmonary artery.
