Linear aerospike and aerospikes in general

[ndiver]

Hello,

Do we have a linear aerospike currently available? I was looking to the XRS-2200 and to the ARCA Space rocket in mind:

 

All i could find is this thread, and i'm surprised to not find more aerospikes (small and big) :

I thank you for your feedbacks

The Mk2 Expansion has an Mk2 linear aerospike.
