This rare grouping of rockets from the Atlantic Research Corporation showcase models that were in production in conjunction with NASA to study payload re-entry into the atmosphere. Most notable is the Trailblazer II used to bring payload to and back from space and study reentry—quite a historic piece in NASA history. This piece is compete with all the fins intact. The other rockets are missing some fins but should be easily recreated / 3D printed but I decided to leave them as-is. The rockets are made of solid aluminum that has been machined. Definitely not a consumer model but an industry model that was sent to select clients. The three are sold as a unique set and compliment each other well as a group. The 2 larger rockets measure 12” long and are mounted on 5 1/4” bases. Sold as a set
