Depending on how old your prof is, he could also be talking about Typhon LR, a ramjet powered Terrier replacement.  Typhon SR evolved into Standard MR, and Typhon LR might be seen as a relative of Standard ER.

Looks like they have an SM-6 Block IB up there too. 

"On Jan. 17, the Navy approved plans to develop a Dual Thrust Rocket Motor with a 21-
inch diameter for the SM-6, which is currently fielded with a 13.5-inch propulsion package.
The new rocket motor would sit atop the current 21-inch booster, producing a new variant
of the missile: the SM-6 Block IB"

Streamlined it ain't.  :o

Talking about the grey missile at top right?  Surprised they kept the forward fuselage at13.5 inches, but I guess that's the minimum-change solution to get improved kinematics without redesigning the warhead or seeker at all.

I think that would work for now given that this had come in as an unfunded priority from the CNO that they wanted to move fast  IIRC. They could work on upgrading the seeker and warhead in future variants.

Are they really viewing it primarily as an ASuW weapon?

I think that this may be a mistake in the slide. Even if the upgrade was primarily meant to enhance its ASuW capability it should still retain the AAW and SBT roles unless they have done away with some of the agility requirements which would be very strange.

I think it may just be that the person who made this slide doesn't understand how Venn diagrams work.

I wonder if they'll ever look at a powered 3rd stage for the SM-6 IB to go after BGVs.

What's the max altitude for the SM6? For gliders you are looking at altitudes of around 40-60 km unless you want to wait till the very last minute and get terminal defense. I think if the BGV threat to ships materializes they'll probably seek a new weapon to tackle that.

SM-6 IB uses the 21" booster and 2nd stage of the SM-3 Block IIA so it would definitely have the ISP to get an aerodynamic 3rd stage up there, and up to speed.

Classified, I've seen 33km+ thrown about for the base weapon. With the new motor, likely a lot more.

There was an early SM-3 test where, after the 2nd stage burned out, they let the 3rd stage (dummy mass) free flight.  They were counting out as it continued to climb, "330,000 feet. . .340,000 feet" and it was still moving like a bat out of hell.  The point being that even the existing SM-6's altitude is likely limited by airframe stability in the thin air.
