But can it reach Mach 10 in 5 seconds after launch? The Sprint ABM had 3.0 MN of thrust and only massed 3.4 tonnes, a liftoff TWR of 88.
The article was about satellite-launch market, not weapons.

It's an inaccurate clickbait headline. The fastest rocket in the world is the 3-stage Delta IV that is launching PSP tomorrow morning.

Yes, except that by the time Delta 4H/Star 48 is going that fast, it is no longer "in the world", is it?!

In terms of flat out "zero to 60" acceleration for an orbital launch vehicle, what about Japan's SS-520?  18 tonnes of liftoff thrust for a 2.6 tonne launch vehicle, but no future plans to launch perhaps.

I think a valid comparison of this type might be time to orbital velocity - "zero to orbit".

Just move past the title, it's an interesting article.
The Solar Probe will be the fastest, not the rocket launching it

Unfortunately, the SS-520 launch didn't have visual indication of altitude
For an accurate comparison, it must be taken into account that at the same altitude the distance traveled may differ.

ESA: Preparing for Vega-C

Quote
At the end of 2019 Vega-C will be launched from Europe’s Spaceport in French Guiana increasing performance from Vega’s current 1.5 t to about 2.2 t in its reference 700 km polar orbit, with no increase in launch costs.
Vega-C's first stage is based on the P120, the largest single segment carbon fibre solid-propellant rocket motor ever built. It was successfully tested in July 2018. Its development relies on new technologies derived from Vega’s current first stage P80 motor. Two or four P120C motors will also be used for the liftoff boosters on Ariane 6.
Vega-C’s 3.3 m diameter fairing will accommodate larger payloads such as Earth observation satellites of more than two tonnes, and ESA’s Space Rider reentry vehicle.
The Vega launch pad and mobile gantry are being modified to accommodate Vega-C leading into a period when launch facilities will accommodate both vehicles.

Focus on Vega developments

Details of Vega’s developments were presented at the 69th International Astronautical Congress on 1–5 October 2018, in Bremen, Germany (http://www.iafastro.org/). Download the presentation here (.pdf) and paper submitted to the IAC here (.pdf).

These Vega developments are the result of the vision set out at the ESA Council Meeting at Ministerial Level in 2014. In November 2019, the Ministerial Council will meet again to discuss Space19+ to direct Europe’s ‘next generation’ ambitions in space, and address the challenges facing not only the European space sector but also European society as a whole.

Production line of VEGA classic at @RuagSpace Emmen with the last three fairing sets in final assembly. Making room for the first @Avio_Group @vega_sts VEGA C which is already in the oven. Note the old (classic) and the new (VEGA C) Horizontal Machining Jigs to the right.

That bit about uprating AVUM+ into VENUS (first version being a hybrid mode service module with both liquid and electric propulsion, as a service module for Space Rider)(second version being what appears to be a pure SEP stage/tug) is pretty interesting. I wonder how generic VENUS in its second form is, as in can it fly on a different small rocket though. I suppose if you can pay, ESA can deliver?

Interesting is that Vega C updates also the AVUM last stage aiming to reduce non-ESA components.
- reduce, but not eliminate/replace all of them?
- haven't seen which specific parts will be replaced and which will remain foreign.
According to this: 2015 presentation, p11
-- Russian tank - replace with Airbus tank
-- US tank - replace with Airbus tank
-- Ukraine engine - replace with Airbus engine

Does anybody have more info on this Airbus engine?

Also, how does that domestication drive fit with the Vega E last stage engine, where some sources mention it'll be LOX/Methane co-developed with Russia?

What other (major) components remain in Vega C that are of non-ESA origin?

Otherwise, a nice progression AVUM+ -> small satellites dispenser -> reusable/returnable orbital plane -> space tug. Is SpaceRider/IXV scalable to human-rated size? Can some ATV-derived systems or structures be utilized for that?

Those are old plans. While most parts are still being "europeanised", Vega-C's AVUM+ will retain the RD-869 engine.  As for Vega-E; Avio worked with Russia on the LM10 MIRA, a demonstrator engine, but the production engine (the M10) is being developed in western Europe.

At the South Australian Italian Association dinner for Paolo Nespoli last night, it was announced that Avio is looking to launch its vehicles from South Australia. This is presumably Vega-C using the Southern Launch site at Whalers Bay.

Interesting.

I wonder what the politics behind this are. At first look it doesn't seem that maintaining two launchsites half a globe apart makes much sense.

Are there any orbital benefits for launching from Australia?

Edit: Spelling and Grammar fixed.

Vega can already do polar orbit from Kourou, but a higher latitude launch site would help payload capacity a bit. Probably not hugely though (tens of kg?)

It does seem a bit left-field.  Are you sure they meant Vega-C and not the new Vega-derived micro launcher?

I can only imagine the idea is to be closer to the asian market, which makes more sense for small launchers.

Interesting and a little odd development of Avio starts launches from South Australia.
I searched "Whalers Bay Australia" on google maps. It goes to Thistle Island. The Whaler Bay is at the north side, AFAIK a orbital launch side should be located at the South West side of the island.
The launches could go:  South <10deg east. or totally west.
This is the compete opposite from CSG, there they can launch ~5 South from East, to North (? a little west).

I can't imagine a P120C launching away from CSG. But Vega Light or a dual Z40 booster variant could be possible.
Avio ships Z40, Z23 and Z9A stages loades to CSG, they could also ship them to Australia. But the P120c are casted at the Regulus plant at CSG. They can't be shipped (safety regulations). 
Or Avio is looking at their Lyra (Myra engine) project. ...

The speaker didn't say which launch vehicle would be used. The use of Vega-C was an assumption on my part, as that was the launcher I was most familiar with. There could certainly be other launchers that Avio is considering.

To be clear, Whalers Bay is at the bottom tip of the peninsular, not from Thistle Island. It was chosen as it was close to Port Lincoln and Adelaide and allows access to Sun synchronous orbits. Attached image shows the launch azimuth's available.

Transfer to test bench of P120C motor for Vega-C

The first qualification model of the P120C solid-propellant rocket motor, in the configuration for Vega-C, was transferred to the test stand in December to prepare for its first hot firing at Europe’s Spaceport in Kourou, French Guiana on 28 January 2019.

The P120C is 13.5 m long and 3.4 m in diameter, and contains 142 tonnes of solid propellant.
