This set includes six (6) BLU-27A/B 750lb Napalm canisters with rounded nose and tail fairings. 

3D printed in one piece (with separate MS3314 suspension lugs), these are almost ready to use right out of the package. Some light sanding to remove the remnants of the print supports will be required on the aft end, and you'll need to remove the small pin on the forward fairing and sand smooth. 

These were used extensively during the Vietnam War.
