Default Enerjet D21

I was perusing the YOR plans website recently, and ran across the announcement flier for the Enerjet 18mm D21 motor. Did these ever make it into production? Has anyone ever actually seen one?

The D21 never made it into production at Centuri/Enerjet. A small number of prototypes were made as a proof of concept only.

Aerotech made an identical motor for years before their facility fire.

I have seen an unloaded Enerjet D21 casing and the packaging for the motor.

This motor never made it into commercial production.

The D21 story is in the new Sport Rocketry.

Describe it relative to released packaging. Including repacks and caselots.

Centuri packaging was awesome. MPC too.

Composite Dynamics (2) 18mm D motors were CA certified but not NAR certified due to localization.

The EJ D21 was prototyped but not marketed.

AT has a 18mm D/E

CTI has a 18mm D/E/F

USR . . .
