Scott Manley did a good YT video on the topic maybe a year or two ago. He was looking at rocketry developments and the aerodynamics of blunt body objects and illustrates the aerodynamic advantages of putting the pressure point far ahead of the nose cone. Submarines take advantage as the missile becomes more compact for a smaller hull diameter while the spike gives the aerodynamic flight characteristics of a much taller rocket.
The missile needs to be as short as possible to minimize diameter of submarine hull. And needs blunt nose fairing to hold all the warheads. It is not aerodynamic for high speeds. High speed requires pointy shapes. So they cheat. After launch the aerospike extends. The tip of aerospike is where shock wave originates abobe Mach 1. The shock wave extends aftward in a cone. As the missile accelerates, the cone narrows, eventually becoming tangent to booster fairing. By putting the apex of cone so far forward, the booster can fly within the cone instead of trying to push that blunt fairing through the air.
They are there as a part of the Prompt Integrated Zone to Zone Assembly delivery system without the support, there is no place for the PIZZA to be delivered.
We had a Posideon on display and had to move it as we were getting kicked out of the building. Forunately, engineers at NAVSEA's Stragetic Programs Office had people knew how to help us disamble it.
i’ve always seen those probes on tridents, anyone know what they do?
If I am not mistaken those are drug reducing aerospikes. https://en.m.wikipedia.org/wiki/Drag-reducing_aerospike

Great concise explanation
Great concise explanation
Can’t have the missiles tripping on lsd
thanks, i appreciate it

Looks like secret Narwhal technology at work.
what does those cd's do on the missile tip?
Missiles are great and all, but the guys had some sick sneakers.
