This list of major Apollo manufacturers is from Chariots for Apollo. Which of them still make aerospace (spacecraft or aircraft) components today?

  • AC Delco: inertial measuring unit, gyroscopes
  • Aerojet-General: service module engine
  • Aeronca: honeycomb panels
  • AiResearch: command module environmental control
  • Allison/Airite Products: fuel components
  • AVCO: heat shield
  • Beech Aircraft: supercritical gas storage
  • Bell Aerospace: ascent stage propulsion
  • Bell Aerosystems: RCS fuel tanks
  • Boeing: S-IC first stage, lunar rovers
  • Collins Radio: telecommunications
  • Douglas Aircraft: S-IVB third stage
  • Elgin National Watch: sequencer
  • Grumman: lunar module
  • Hamilton Standard: lunar module environmental control
  • Honeywell: stabilization, control
  • IBM: instrument unit, mission control computers
  • International Latex (ILC Dover): space suits
  • Kollsman Instrument: optics
  • Link: simulators
  • Lockheed: launch escape motor, pitch motor
  • Marquardt: reaction control systems
  • MIT (Draper): guidance and navigation
  • North American Aviation (Rockwell): S-II second stage, command module, service module, launch escape system, descent stage propulsion, instrument unit adapter
  • Northrop: recovery system
  • Nortronics: Q ball
  • Pratt and Whitney: fuel cell
  • Radiation Inc.: S-II stage telemetry
  • Raytheon: computers
  • RCA: communications, antennas, VHF, TV, radar, lunar module guidance
  • Rocketdyne: descent and ascent stage propulsion
  • Simmonds Precision Products: propellant mixture controls
  • Thiokol: tower jettison motor
  • Westinghouse Electric: inverters

Please add your answers to the Community Wiki below. I've already written a few to get things started.

Considering that companies get bought (all or in part), sold (all or in part), and go out of business, please limit your answers to the fate of the division that was responsible for the Apollo program. And of course, tell us who owns that division now.

    $\begingroup$ List seems quite incomplete. Ford Aeronutronics division built Mission Control. Chrysler built the Saturn 1B. $\endgroup$ – Organic Marble May 30 at 2:58
  • $\begingroup$ @OrganicMarble: The source that I took this from seemed to be concerned with the lunar-mission spacecrafts. Also, the source specifies contracts >= $5 million. If enough people flag your comment as helpful, then I will add those contractors to question and wiki answer. $\endgroup$ – DrSheldon May 30 at 3:09

  • AC Delco: Originally were separated as AC Spark Plugs and Delco Electronics during Apollo era under GM later to be joined as ACDelco. Also helped provide parts for the lunar rover. There website doesn't say anything about any aerospace projects but they have over 90,000 auto parts which many of them could be used in aerospace technology.

  • Aerojet-General: Merged with Rocketdyne, still in the rocket business.

  • Aeronca: Still in business

  • AiResearch: Yes, as Honeywell. Merged with Signal Oil & Gas in 1964 to become Signal, merged with Allied Corp. in 1985 to become Allied-Signal, purchased Honeywell in 1999 and adopted its name. Honeywell is a major manufacturer of aircraft and spacecraft parts.

  • Allison/Airite Products:

  • AVCO:

  • Beech Aircraft: Beech is also known as Beechcraft, it's still making airplanes as part of Textron

  • Bell Aerospace: Was actually bought by Textron Corp. in 1960 and went on as Bell Aerospace Textron. Parent company of Bell Aerosystems and the only existing part of the company left, Bell Helicopter, which makes the Osprey, AH-1Z (aka Apache), and UH-1Y (aka Huey) for the military as well as plenty of civilian helicopters too.

  • Bell Aerosystems: Its parent company was Bell Aerospace Textron and was the division that developed the engines for the Agena A, B, D and Target Vehicle versions. Bell Helicopter is only surviving division of Bell Aerospace.

  • Boeing: One of the biggest aerospace manufacturers still existing, responsible for the 702 satellite bus, CST-100 spacecraft, and the SLS core stage.

  • Collins Radio: Purchased by Rockwell to become Rockwell Collins, got bought by United Technologies Corporation, still around as Collins Aerospace division of UTC.

  • Douglas Aircraft: Merged with McDonnell in 1967, merged with Boeing in 1997.

  • Elgin National Watch:

  • Grumman: Merged with Northrop, now the prime contractor for the James Webb Space Telescope.

  • Hamilton Standard: Still in business, famous for airplane propellers but they make other components

  • Honeywell: Yes. Acquired by Allied-Signal in 1999 but kept name. Honeywell is a major manufacturer of aircraft and spacecraft parts.

  • IBM: Still around, of course, with vaguely described aerospace/defense activities.

  • International Latex (ILC Dover):

  • Kollsman Instrument:

  • Link: Per info from Link Trainer, via acquisitions from Hughes Training and Raytheon Systems, now the Link Simulation & Training division of L3 Technologies. They continue to make aerospace simulators.

  • Lockheed: Merged with Martin Marietta, now Lockheed Martin

  • Marquardt: Split, sold, and resold; their bipropellant thrusters are now owned by Aerojet Rocketdyne.

  • MIT (Draper): Still working on many projects including aerospace, as of this writing the organization's web page has a section called "Draper to Advance NASA's Human Lander Mission"

  • North American Aviation (Rockwell): Got bought by United Technologies Corporation, still around as Collins Aerospace division of UTC.

  • Northrop: Merged with Grumman, now the prime contractor for the James Webb Space Telescope.

  • Nortronics:

  • Pratt and Whitney:

  • Radiation Inc.: Merged with Harris Corp, still does aerospace work today, such as work with the GOES-R satellites

  • Raytheon: Yes, still same name today, and builder of missiles, radars, and other aerospace components.

  • RCA: No. Spun off from General Electric in 1932, reacquired by GE in 1986, and dismantled. The division which made electronics for Apollo was sold to Thomson Consumer Electronics. RCA today exists only as a trademark for consumer products. GE is a significant defense contractor, but these involve divisions that had nothing to do with RCA.

  • Rocketdyne: Merged with Aerojet, still in the rocket business.

  • Simmonds Precision Products:

  • Thiokol: Merged to form ATK, then Orbital ATK, and now is a part of Northrup Grumman, and still in the business. They still build solid rocket motors today.

  • Westinghouse Electric:
