A gaggle of Pershings - or should it be a murder? One to fly, three to stand by. Thank you Carl and Gordy.

OMG.... Look at how neat and tidy that work bench is!
How do you ever find anything!

Btw, Nice missles!

On the first three missiles there is a flare out of the nose cone near its base. Is that scale-accurate?

Joe

The fist three are Pershing II's where the different one is a Pershing 1A.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !

FYI, I grouping of Pershings is referred to as a..............

Thank you. I'll be here all week.

Stay in school, kids.

Technically there is a change in diameter on the P-1a nosecone also. The angle of the G&C adapter is more acute than the angle of the warhead fairing to the radome. The reduction goes from 40" to 32" in about 51" of length. I think that Gordy has it on his cones but it is not really needed for a semi-scale model.

As for the P-II there is assuredly a frustum in the adapter from the 40" diameter airframe to the base of the G&C/A, just there is some variability in the length needed to achieve the reduction and the distance in which it happens. On the PII is is about 26"

Yep, there is.

The drawing shows the difference in the Pershing 1a and the Pershing II

There was also a Pershing II that used the Pershing Ia booster and the more colorful test round colors.

According to both written and anecdotal information the P-II warhead flew in four guises:

P1-a Full stack
P1-a First stage
P-II First Stage
P-II Full stack

There is a nice collection of images of these excluding the P-1a First stage at this website:

http://kevinmcconathy.com/pershing/Default.htm

There is some discussion that the original P-II was to use the same booster air vanes as the P-1a, as it shared the first stage. While the general configuration in the attached pdf is somewhat representational, note the drawing on the second page which indicated that the booster vanes are shown rotated 45 degrees. Also of note is that the P-II second stage supposedly shared the use of blow-out ports for boost termination to stop the second stage coasting behind the re-entry section. These were at a more shallow angle to the skin so the ellipse was smaller - just never seen it in imagery.

There are some drawings with a shorter adapater yet seem to have a missile length of 417.55" for the shorter adapter while 413.50" to the tube base with the longer adapter.

Curiouser and curiouser since the P-1a was 416" from tip to base with the air-vanes flush to the base.
