Today, one of the 3D printing folks could make such 5:1 BT-5 ogives. Also:

Those "super-caliber cone" ASP rounds look like the pictures in Dr. Richard Morrow's book, "Small Sounding Rockets" (which--the last I'd heard--he was working on reprinting, perhaps via POD [Print On Demand] publishing [here http://www.google.com/search?ei=9UK...0.VEJK4p7 cMxM is his book]). He also covered a two-stage sounding rocket that used that mushroom cloud sample-collecting nose cone, called the ASCAMP (see: http://www.google.com/search?source...160.Xuu7eh_FuMw ), and:

The ASCAMP used the delta-finned ASP as its first stage. The SCAMP second stage, which had Aerobee 350-like fins (although much smaller) and the "super-caliber cone," used the same "Baby Sergeant" rocket motor as that used for the Jupiter-C/Juno I and Juno II high-speed solid propellant upper stages.


HERE YOU GO . . .
