Hardware row: what the neighbors are building
Within a short drive of Main Street, companies are building reentry capsules that come home with factory goods from orbit, a portable nuclear microreactor, satellites the size of a bus, a commercial space station and factories that run themselves. Most have no storefront and no sign you’d notice from the road. Here are 19 of them, each in its own words, on a map you can filter.
Not an official City of El Segundo page. Not affiliated with, sponsored by or reviewed by any company named here, and nobody paid to be listed. Written by Claude (Opus 5.5) with a Claude research helper on Nov 8, 2026, at the request of Michael Hoydich. Each description is quoted from the company’s own site or release and links to it. Distances are our straight-line estimates from City Hall at 350 Main Street; companies with no published street address are placed at the middle of their city. Inclusion is not an endorsement, and some of these companies make weapons. Paintings are public domain works from the Cleveland Museum of Art’s open access collection.

Spacecraft and satellites
Inversion
Los Angeles (its site names no street) · not mapped
Builds:Arc is a space-based delivery vehicle designed for the precision delivery of cargo, to anywhere on earth, in under an hour.listingsource
Three things stand out from the companies’ own pages. First, a lot of new space work is about getting things back down, not only up: Varda brings capsules home from orbit, and Inversion pitches a vehicle for delivering cargo from space. Second, several of the newest names are factories first. Hadrian, Divergent and Northwood all describe themselves by what and how they manufacture. Third, the old anchors are still here and still shipping: Boeing sent its last O3b mPOWER satellites from El Segundo in September, and Northrop Grumman’s Redondo Beach dateline sat on 21 new satellites in October.
That reading is ours, from the quotes above. estimate
Street addresses for Boeing, RTX, Radiant, Epirus, Castelion, Northwood and Divergent; their own pages name only the city.
Where in Los Angeles Apex and Inversion are, so they are listed but not mapped.
Whether Relativity Space still uses the Long Beach address from its 2021 release.
Head counts, except The Aerospace Corporation’s 2022 figure.
Exact quote wording came back through a web fetch tool; the links open each original.
Looked at and left out: Astranis (its factory is in San Francisco) and Ursa Major (Colorado, no Los Angeles site found on its own pages).
