As an European, I often use Airbus also (or Airbus Defence and Space, a subsidiary), the main competitor to Boeing. Formerly known as EADS but you can use this name too (European Aeronautic Defense and Space).

Airbus just sounds goofy when applied to space EADS is great! Who doesn't like a good acronym? Calling it European also implies the 'merging' of nation-states into consolidated territories under a one-world government.

Shadowrun has some pretty cool corporations I use:

Saeder-Krupp Heavy Industries: Railguns, Power-plants and shipyards.

Wuxing Incorporated: Fire Controls and Sensors

Renraku Computer Systems: Fire Controls and Sensors

Shiawase Corporation: Lasers, Shields, and Jump-Drives

Ares Macrotechnology: Lasers, Railguns, Gauss Canons and shipyards.

Cross-Applies Technologies: Shields, Sensors,and Lasers

I also like using real and semi-real companies:

Lockheed-Boeing Aeronautics: Engines and shipyards

Rolls Royce Intergalactic: Engines and shipyards

BEA Systems: Beam point-defense and CIWS

Mitsubishi-Sugo (Actually from Cyberpunk): Engines and shipyards

Raytheon: Sensors, Fire Controls

I wish there was a way to store corp names and which technologies to apply them to so they'd appear automatically.

I'd like some more ideas since the US and Japan are over-represented IMO. Perhaps TaTa but I don't really know that they do outside of engines and I don't think they'd compete with Boeing an such.

Fictional mergers (Like Lockheed-Boeing) and fictional Space subsidiaries (Rolls Royce Intergalactic) of existing companies are my favorite, so if anyone has any ideas about that feel free to PM me so I can write them down.

For engines:

Rolls-Royce
General Motors
Pratt & Whitney
Energomash

then there is

BAE Systems, maybe for weapons? Also Vickers, but I believe they are defunct now.

for engines also:
Snecma - part of SAFRAN - french industrial conglomerate.
NPO Saturn - main manufacturer of aircraft engines in Russia.

for electronic / weapons systems:
EADS (EU industrial conglomerate)
Almaz-Antey (Russian conglomerate focused on Anti-Air defence systems manufacturing)

My goto is to smack the random company name button a few times, then come up with something based on that, keeping a list of the ones I use in my text file for that particular Aurora game. That way I can do things like have some companies expand their field of expertise over time, or have them merge, or things like that. (Works best if you have multiple name themes set up for your race, so you get a wider variety of output to work with.)

Yes, it's shameless RP fluff, but what the hell.

I use Raytheon for sensors, General Dynamics for power plants/engines, national bureaus of research and development for jump drives, stealth technology, stealth engines, and beam weapons, and Rheinmetall for turrets.

Thanks, this will prove useful! I'm playing the 'United Nations of Earth' (which has only half of the nations of Earth in truth, the rest being outside) and I need to use names from various countries.

Has someone compiled (and want to share) a list of manufacturing companies? I often fall short on good names ... I mean plausible Earth companies like Boeing, Airbus, Rheinmetall, Chengdu Aerospace Corporation etc.
