While I cannot tell you much about the early Little Joes I can provide some information about the Little Joe II series. For some reason, I find this rocket very interesting. Perhaps its the way it looks like a cross between old and new... Excerpted from _Apollo_Little_Joe_II_ by Centuri Engineering Company, Inc., copyright 1968: The Little Joe II is a solid rocket booster designed and produced by the Convair Division of General Dynamics for the NASA Apollo Program. Its specific purpose was the man-rating of the Apollo Launch Escape System which pulls the three moon-bound astronauts to safety in the event of a catastrophic Saturn V booster failure. Little Joe II uses a cluster of up to seven ALGOL 1D solid propellant motors, which produce a combined total thrust of 860,000 pounds. It is the most powerful all [sic] solid propellant rocket ever flown in the United States [This was written before the advent of the space shuttle!]. All of the unmanned Launch Escape qualification flight tests, using the Little Joe II booster, were conducted at the White Sands Missle Range in New Mexico between August 28, 1963 and January 20, 1966. Following is a summary of the Little Joe II flights: [A boilerplate is an R&D vehicle that simulates a production craft, whereas a spacecraft refers to an actual production model.] QTV - Test Vehicle August 28, 1963 o dummy Launch Escape System (LES) o dummy Command & Service Modules o Booster: Cluster of seven motors: a center ALGOL surrounded by six Recruits o Liftoff Weight: 57,165 lbs. o Abort Altitude: No abort capability o Test Objective: Check out the Little Joe II booster, not the LES Boilerplate - 12 May 13, 1964 o live LES o boilerplate Command Module (CM) o Booster: One ALGOL motor, six Recruits o Liftoff Weight: 57,930 lbs. o Abort Altitude: 19,400 ft. o Test Objective: Transonic buffeting abort Boilerplate - 23 December 8, 1964 o live LES o boilerplate Command Module (CM) o Booster: Two ALGOL motors, four Recruit motors o Liftoff Weight: 94,331 lbs. o Abort Altitude: 32,000 ft. o Test Objective: Maximum aerodynamic pressure abort Boilerplate - 22 May 19, 1965 o live LES o boilerplate Command Module (CM) o Booster: Six ALGOL motors o Liftoff Weight: 177,189 lbs. o Abort Altitude: 12,400 ft.
