The Conestoga-1000 Series by EER was an attempt to create a small modular launch vehicle consisting of proven off-the-shelf components. While the Castor-4B formed the basic vehicle in multi-unit parallel mountings, different three axis stabilized upper-stages were planned, all based on Thiokol Star motors. A small hydrazine powered HMACS (Hydrazine Maneuvering and Attitude Control System) stage could also be added for increased performance and accuracy. More configurations, featuring stretched Castor motors were planned. After the first vehicle failed and the MSTI 5 satellite planned for the second mission was cancelled, the company ran out of money and the program was shelved.
