The Aerospace Corporation exists to tell the United States government whether a rocket is going to work before it launches something irreplaceable on top of it. It builds nothing. It sells no product. It is a nonprofit that has spent 65 years as the technical conscience of America's national security space program, and its most recent public Form 990, for the fiscal year that ended September 30, 2024, shows an institution that survives on almost exactly the same terms as MITRE: government contracts in, salaries out, and no fortune in between. What makes Aerospace worth its own entry is where its one real pile of invested money actually sits. It is not an endowment. It is a pension. Everything below is from the filing.
Born to remove a conflict of interest
Aerospace was incorporated in June 1960 in El Segundo, California, and the reason it exists is a small masterpiece of institutional design. The Air Force's ballistic missile and space programs were getting their systems engineering from a for-profit firm, Space Technology Laboratories, a division of Ramo-Wooldridge, and Congress did not like that a private company held such a privileged, conflicted position over billions of dollars of government hardware. A 1959 House report recommended converting that systems-engineering role into a nonprofit that could not compete with industry and had no product to sell, so its advice would be trusted (Wikipedia, "The Aerospace Corporation"). Its first president was Ivan Getting, one of the fathers of GPS, who described navigation satellites as lighthouses in the sky and whose team shared the 1992 Collier Trophy for the Global Positioning System (Aerospace, "A brief history of GPS").
That founding logic is still the entire business model. Aerospace operates a federally funded research and development center for national security space, sponsored today through Space Systems Command under the U.S. Space Force, and it also supports the National Reconnaissance Office (Aerospace, "The value of an FFRDC"). Its signature work is mission assurance: it is the only FFRDC chartered to independently verify a launch vehicle before a national security payload flies, using a proprietary database of past launch anomalies to catch the failure before it happens. That role hardened after the 1998 and 1999 wave of Titan and Delta launch failures, roughly three billion dollars lost, which led to the Broad Area Review and cemented Aerospace as the government's independent check on the rocket (SpaceNews, "Air Force releases space launch review results").
Where the money comes from, and where it goes
Revenue for the year was $1,372,694,000, and it is reported in round thousands because Aerospace, unusually, keeps its books that way. Of that, $1,365,022,504 was program service revenue, meaning contract payments. Investment income was $2,277,490, again a rounding error. The two program lines on the return are the national security space work, which cost $1,061,863,297, and the Civil Systems Group, which does NASA and NOAA work and cost $202,402,594. One customer dominates, and that customer wears a uniform.
Expenses were $1,328,028,000, and salaries, other compensation, and benefits were $1,052,470,496, close to eighty cents on the dollar, the same people-heavy shape every research institution shows. Aerospace employs about 5,446 people. The surplus was $44,666,000, a hair over three percent, the fee-limited margin an FFRDC runs on. Its largest outside vendors are all software and technology firms, a computer-services company at $9,544,383, then Microsoft, World Wide Technology, and Cisco, the procurement signature of a systems-engineering house that produces analysis and certifications and buys computers rather than bending metal.
The compensation schedule holds a detail worth pausing on. The president and CEO who signed this return, Steve Isakowitz, earned $1,952,121 plus $308,621 in other compensation. But partway down the officer list sits a vice president named T. Pemberton at $542,627. In October 2025, after this fiscal year closed, Tanya Pemberton became the corporation's president and CEO (Aerospace, "Aerospace names Tanya Pemberton next president and CEO"). You are reading, in the middle of a routine officer table, the next chief executive one promotion before the fact. There is also a reason a nonprofit executive earns nearly two million dollars here: after a 1995 GAO finding that Aerospace executive salary costs had jumped 78 percent in three years, Congress capped compensation at federally sponsored FFRDCs at Executive Schedule Level I (GAO report NSIAD-95-75). The pay is high for a charity and capped for its industry, both at once.
How it invests, which is through the retirement plan
Read Aerospace's balance sheet looking for an endowment and you will not find one. Investments in publicly traded securities: zero. Investments in other securities: zero. Like MITRE, Aerospace does not run a portfolio, because a cost-reimbursement contractor has nothing to endow. But it is not true that Aerospace has no exposure to the markets, and this is the point this series wants to draw out. The return reports $409,588,199 in other assets, and on the liability side it carries $545,363,755 in other liabilities. That pairing is the signature of a pension. Aerospace has promised its workforce a defined-benefit retirement, and the assets set aside to pay for it are invested in the same equity and bond markets that every corporate and state pension relies on.
So Aerospace competes in the markets, just not as an endowment. It competes as a retirement plan, and it competes from behind. Its total liabilities are $833,404,450 against only $432,332,550 in net assets, which is the thinnest cushion relative to revenue of any research institution in this series. A large share of those liabilities is the pension and post-retirement obligation, the same kind of promise that has strained corporate balance sheets and state budgets for a generation. The ordinary reader with a pension, or whose city has one, is looking at a familiar problem in a NASA supplier's books: a benefit promised in the past, funded by a portfolio that has to earn its keep in the market, and a gap that shows up as a liability. When those pension assets have a good year in the S&P 500, so does the firefighter's fund and the retiree's account, because they are all in the same market. When they have a bad year, the gap widens for all of them at once.
What it owes, and what wears out
Beyond the pension, Aerospace carries $134,903,228 in secured mortgages and notes, debt against its campuses, and $153,137,467 in ordinary payables. On the physical side, it holds $1,390,372,744 of land, buildings, and equipment at cost against $767,615,557 of accumulated depreciation, leaving $622,757,187 net. More than half its capital base has been written down, the same quiet erosion that runs through every one of these institutions: labs, test chambers, and clean rooms aging on the books while the mission stays young.
For how long
As long as there is a national security space program that wants an honest broker who builds nothing, which is to say indefinitely, with a tailwind. Aerospace has done this job for 65 years. The Space Force took its first budget dip in the fiscal 2025 request, but the fiscal 2026 request plus reconciliation funds point to a large increase driven by the Golden Dome missile-defense initiative (Aerospace, Center for Space Policy and Strategy budget analysis). More money for space means more rockets to certify. The risk to Aerospace is not the market and not the mission. It is the same risk MITRE carries, that the appropriations lurch and the contract that funds nearly everything gets renegotiated, plus one MITRE mostly does not carry: a pension promise that has to be paid whether the market cooperates or not. An FFRDC with no endowment is exposed to its sponsor. An FFRDC with a defined-benefit plan is also exposed to the market, through the one door it cannot close.
