Dual Castor-120, the second one wit vacuum optimized nozzle, perhaps?

Sorry, no. This is not a new rocket.

Minotaur-C is using a payload fairing that is only used by Minotaur and OBV launchers is what I read. So if it is a rebranded Taurus it is not using the previous fairing system. So if my previous sentence stands correct it may be using Payload fairing used by Minotaur-1 or II otherwise I know that it is not the fairing system used on the failed Taurus-XL as it is worded as indicating that the Fairing and rest of the launcher originate from only OBV, Minotaur and Pegasus-XL.

My understanding is that this mission will use the 92" fairing, which is from the Taurus XL catalog and has flown successfully. The failed Taurus XL missions used the 63" fairing.
Please note: OBV, Pegasus XL, Minotaur I & III/IV/V, and Taurus XL all share various ATK motors.

There were multiple things that had to go wrong with the Taurus fairing for it not to work. They've fixed those problems. I would be more worried about the next Falcon 9 v1.1 launch than I would about another Taurus XL fairing problem. Read a little about it here (though it doesn't tell the whole story) :

No, just one thing.

I wonder if the renaming of Taurus to Minotaur C (assuming this is what is happening) might be avionics-based. Minotaur was equipped from the outset with an upgraded version of Orbital's older Pegasus and Taurus avionics system. This included the inclusion of Orbital's Modular Avionics Control Hardware (MACH) system and the use of high-data rate telemetry. MACH was originally developed, as I understand it, for OSP and Target Launch Vehicle. Perhaps a Taurus equipped with updated Minotaur avionics suite is now going to be called "Minotaur C".
Just a guess.

You're on to something there, Ed. But it's not just a MACH upgrade; it's cutting loose the soiled baggage of the past.

Unless it uses different motors, I'll still call it Taurus.

Could you elaborate please Robotbeat, instead of just saying "you're wrong"?

If they decided to rename it, we have no choice but to use the new name. Very few are still using Taurus II to describe Orbital's Antares. Do you still call a post merger Boeing 717 a MD-95 or DC-9?
btw. When Kim Keller wrote: When you folks see pictures of it I believe you will indeed recognize it. I was so tempted to post a picture of a Saturn V with a big old question mark, then thought better of it

I'll call it whatever name Orbital assigns, but if it is simply a rename its reliability record will still include launches made under its old name.

Since I was involved in the investigation you'll have to be a bit more specific.

Wasn't a material uncontrolled secondary property that failed to propagate the fissure?

If that's meant to indicate that the frangible joint was not manufactured by a subcontractor to aerospace requirements, then you're right.

So it actually uses the "standard" Minotaur fairing, and not the same fairing as the Taurus.
