The air system vessel is a class for blasters significantly larger than air system blasters, hence the name "vessel". Apart from this, the air system vessel series is essentially a replication of the air system line, as they share the same firing method and many other similarities. This is also the only blaster class to already fill the slot of where the number would go. As of late 2013, alongside the air system line, the air system vessel line has not been continued into the replacement N-Strike Elite series.
