The Charles Stark Draper Laboratory built the computer that landed human beings on the Moon, and it is still here, in Cambridge, guiding the Navy's missiles and NASA's return to the lunar surface. Of the research institutions in this series, Draper is the one that most resembles MITRE and Aerospace, a contract-funded lab living on government work, and yet its most recent Form 990, for the fiscal year that ended June 27, 2025, shows one thing they do not have: a real investment reserve, a $270 million pool it manages like a small endowment. Draper is the contract shop that saved. Everything below comes from the filing.
The machine that landed on the Moon
Charles Stark Draper, known as Doc, was the father of inertial navigation, the science of knowing where you are and where you are pointed without any signal from outside your vehicle. He founded a teaching laboratory at MIT in the early 1930s that grew into the MIT Instrumentation Laboratory (Wikipedia, "Charles Stark Draper"; Draper, "Origins"). In 1961 the lab won the first contract awarded under the Apollo program, and it produced the Apollo Guidance Computer and the guidance, navigation, and control system that flew on every Apollo mission, including the Apollo 11 landing (Wikipedia, "Apollo Guidance Computer"). That machine, a marvel with less memory than a modern greeting card that plays a song, is the ancestor of everything Draper still does.
The independence came out of conflict. The Instrumentation Laboratory was renamed for Draper in 1970 but remained a division of MIT, and during the Vietnam era, protests over classified military research on a university campus pushed MIT to divest its special laboratories. On July 1, 1973, the Charles Stark Draper Laboratory was spun out as an independent nonprofit corporation (Draper, "Origins"). One point worth stating clearly, because it separates Draper from most of this series: it is not an FFRDC. It is an independent nonprofit engineering lab that contracts with the government, industry, and academia, and it counts FFRDCs among its partners rather than being one (Wikipedia, "Draper Laboratory").
What it does now still runs on Doc Draper's specialty. Draper is the guidance prime for the Navy's submarine-launched ballistic missiles, and its filing notes a heritage that stretches from Polaris to the Trident II D5; in 2022 the Navy awarded it a roughly $2.2 billion contract to support the next-generation Trident guidance system (Draper news release). It wrote software that flew on NASA's Artemis II mission and was selected to deliver science to the far side of the Moon under a NASA commercial lunar contract (NASA, "NASA Selects Draper to Fly Research to Far Side of Moon"). It also runs a growing microsystems and biomedical line, including a September 2024 federal award of up to $90.5 million to adapt its organ-on-a-chip platform for antiviral testing (Draper news release).
How the money moves
Revenue for the year was $949,348,102, and $941,078,629 of it was program service revenue, meaning contracts. Contributions were $1,164,568 and investment income $7,167,145. This is a contract shop, and the shape of the return says so as loudly as MITRE's does. Expenses were $919,457,813, with $484,170,755 in salaries and benefits, and the surplus was $29,890,289. Draper reports that 1,866 of its employees were each paid more than $100,000, on a staff it describes elsewhere as more than 2,300 people across a dozen campuses (Draper, "About").
The chief executive, Jerry Wohletz, who came from BAE Systems in 2022, earned $1,793,133 plus $313,139 in other compensation (SpaceNews). The rest of the officer table runs in the $300,000 to $530,000 range, and the board, unusually studded with retired national security figures, is paid $75,000 to $110,000 a year. The largest outside vendors are construction and staffing firms, led by a construction contractor at $14,250,336, the signature of a lab building out its physical plant.
How it invests, which is the difference
Here is where Draper parts company with its FFRDC cousins. MITRE holds essentially no securities. Aerospace holds none outside its pension. Draper holds a real, diversified investment portfolio: $151,033,859 in publicly traded securities and $119,199,523 in other securities, about $270 million in all. And the schedule behind that number reads exactly like an endowment's asset allocation. Draper's investments are sorted into global equities, global fixed income, absolute return, real assets, private capital, insurance contracts, and hedge funds. That is not a checking account. That is a miniature version of the same institutional portfolio HHMI runs at a hundred times the scale, spread across public and private markets and alternatives.
Which means Draper, alone among the pure defense labs in this series, competes in the markets everyone else relies on. Its $270 million reserve is invested in the same global equities a retiree's index fund holds, the same private capital a state pension chases, the same hedge funds a sovereign wealth fund allocates to. A contract lab does not need a reserve to keep the lights on, because the contracts pay the bills. Draper built one anyway, and the reason is independence. A cushion invested in the markets is an income that does not come from the government, a few years of runway that lets an institution say no, absorb a slow contract cycle, or fund its own research before a customer asks for it. It is a small insurance policy against the exact fragility that MITRE felt in 2025 when its funding nearly lapsed.
What it owes, and what wears out
Draper's liabilities total $295,469,920: $127,934,317 in payables, $65,259,321 in deferred revenue, which is money customers have paid for work not yet done, and $86,729,245 in unsecured notes and loans. On the physical side, it holds $695,485,800 of land, buildings, and equipment at cost against $412,625,731 of accumulated depreciation, leaving $282,860,069 net. Nearly sixty percent of its capital base has been depreciated, the familiar wear of a lab whose instruments and cleanrooms are always one generation behind the frontier they are helping build. Net assets are $605,460,103, a healthier cushion against a billion dollars of spending than any of the FFRDCs carry, precisely because Draper both banked reserves and invested them.
For how long
Draper has existed as a lab since the early 1930s and as an independent nonprofit since 1973, and its filing leans on a 90-year legacy. Its durability comes from a combination the single-sponsor FFRDCs cannot match: a diversified customer base across the Navy, NASA, and the intelligence community, plus a real investment reserve that generates income the government does not control. That does not make it invulnerable. It is still overwhelmingly contract-funded, and a defense lab lives or dies by the programs it is on. But of the four defense and space labs in this series, Draper is the one that took a slice of every good year and put it into the market, and that slice is why it can look at a thin contract year with more calm than a pure pass-through can afford. The lab that computed the path to the Moon also did the more mundane math: keep some, invest it, and you buy yourself the freedom to keep working.
