SAMs can be upgraded by placing an additional SAM on an existing one. This adds an additional missile before having to reload, and in v0.27 the SAM's range is increased when stacked and a preview of this range shown to the player.

			The range of a level 1 SAM is 70 [[Tile\|Tiles]], and the maximum range of a SAM is 150 tiles. A SAM outreaches a [[Hydrogen Bomb]]'s blast radius at level 5.

			The range is calculated with the following formula:

			<math>\text{range}(\text{level}) = \text{maxRange} - \frac{480}{level+5}</math>

			Meaning that a SAM will never be able to reach a range of exactly 150 tiles.
