If this spreads throughout the industry, it could be trouble for big launchers like Falcon Heavy and NG.

I quote: - "low volume, to launch up to 4 at a time (stacked)", ie 8 tons, firmly into FH territory.

Launching stacked from 2 to 8 tonnes is brilliant, since they can fly the same sats on anything from Antares and Soyuz to Ariane 5/6 and Falcon Heavy. Really opens up the market.

This is also where a dial-a-launcher like Atlas V/Vulcan can be more competitive.  IF (and this is a big IF) they can streamline sufficiently to allow for a late addition satellite and "simply" add in a couple solids... that can change things.  Just one 2 tonne satellite on top of another payload and adapter could really make a big difference in how competitive they are priced (cost/kg get much better with more solids, full capacity).

I saw some satellite analyst on Twitter concern-trolling about SpaceX's 2019 manifest not being full (i.e. 30 launches), yet. With responsive satellites like this, there's plenty of time for it to fill up.

Those SES specs were their vision for the future, not an actual order.

I didn't say otherwise.

Big news in satellite communications today: SES (one of the biggest GEO satellite operators, and owner of the O3b MEO constellation too), has announced the design or its future GEO sats:
- fully digital, for completely flexible spectrum/footprint allocation
- use of less expensive commercial components
- low mass, at 2000kg
- low volume, to launch up to 4 at a time (stacked)
- short lifetime, less than 7 years
- cheap, at less than 50M$ to build
- 18 month from contract to GEO slot (vs more than 30 currently)

That's the same philosophy as for the next-gen O3b constellation built by Boeing: fully digital with a phased-array antenna for maximum flexibility

The source is Peter B. de Selding:
https://www.spaceintelreport.com/ses-tells-satellite-builders-prepare-total-rethink-business/

It seems to me they want to exploit SpaceX's reusable rockets fully: quick and cheap launch is required for that kind of satellite
Some are bound for happiness, some are bound to glory, some are bound to live with less, who can tell your story?

At the April FCC meeting they are considering changes to streamline the approval process for small NGSO satellites.

Sciaky’s EBAM Process Achieves Qualification through Lockheed Martin Testing
Quote
Lockheed Martin, which 3D printed both halves of the 46-inch titanium fuel tank domes on an American-made Sciaky EBAM 110 machine, announced last week that the tanks met or exceeded the performance and reliability required by NASA, allowing it to become a standard product option on LM 2100 satellites.

GomSpace to Ship Propulsion Systems to Astrocast
Quote
GomSpace Sweden signed a contract with Astrocast, a Swiss nanosatellites provider, to deliver a propulsion system for each of the 10 nanosatellites in the first orbital plane of the new Astrocast constellation. This will be the first propulsion system operating on a constellation of 3U cubsesats.

A consortium comprised of U.S. U.K., and Canada-based private equity companies agreed to buy Inmarsat for $3.4 billion. The consortium, made up of Apax Partners, Warburg Pincus International, and Canada Pension Plan Investment Board (CPPIB), disclosed the proposal for the takeover last week, although it was made on Jan. 31. Lansdowne Partners, which currently owns 11.4 percent of the company, backed the deal, according to a report from Bloomberg.

Great contract for Iridium, with the DoD:

Quote
Iridium said Sept. 16 that the new seven-year, $738.5 million contract ensures continuity for voice, data, broadcast and other services to Defense Department and associated users.

Quote
Iridium’s 2013 contract was worth $400 million, or roughly $80 million per year. Under the new deal, Iridium stands to receive $105 million per year on average.
