What is Mondaloy and why does it matter?

The problem

High-performance rocket engines need to push hot oxygen through metal parts at extreme pressure. Hot oxygen makes most metals catch fire. Russia solved this in the 1960s. For decades, the US military launched its own spy satellites using Russian-built RD-180 engines because we couldn't make an American equivalent.

In the mid-1990s, two metallurgists at Rockwell International invented a nickel-based superalloy that could survive that environment without igniting or cracking. They called it Mondaloy — a portmanteau of Monica Jacinto and Dallis Hardwick.

After Russia cut off RD-180 servicing in March 2022 over Ukraine sanctions, Mondaloy became the material standing between the United States and a gap in its ability to put national security assets into orbit.

The technical significance

Mondaloy is used in approximately 12 components of the AR1 engine: preburner, turbine rotor, turbine housing, ducts, lines, and hot gas manifold — everything that touches oxygen-rich combustion. It can be cast, forged, and 3D-printed. Two variants exist: Mondaloy 100 and Mondaloy 200, optimised for different temperature and pressure ranges.

The AR1 program was an $804 million public-private partnership between the US Air Force, Aerojet Rocketdyne, and United Launch Alliance. It was designed to be the domestic replacement for the RD-180.

The critical fact

All three US patent applications for Mondaloy were filed between 2001 and 2009. All three were abandoned. The last one expired in December 2012. After that, the composition was technically public from expired filings, but the composition is not the recipe. The recipe is twenty years of process development — how to cast it, heat-treat it, machine it, print it, integrate it — knowledge that lived in human heads, not in any document.

The three people who held the knowledge

One inventor. One qualifier. One funder. Together they held the complete institutional memory of how Mondaloy moved from a lab bench to a flight-qualified rocket engine component.

Co-Inventor & Production Lead

Monica Jacinto Reza

Technical Fellow, Aerojet Rocketdyne → JPL NASA
Columbia University metallurgical engineering (BS). UCLA materials science (MS). Joined Rocketdyne in 1988. Co-invented Mondaloy in the mid-1990s. Spent 25+ years shepherding the alloy from lab composition through Air Force and NASA contracts to flight qualification. Holder of US Patent 2010/0266442 A1. Associate Fellow, AIAA. The only living person who knew the full manufacturing chain from start to finish. Quietly moved from Aerojet Rocketdyne to JPL NASA between 2023–2024, under her family name.

Geographic clustering

Four of five disappearances occurred in the Albuquerque / Los Alamos / Kirtland nexus. All four New Mexico cases involve individuals connected to facilities that share classified networks: LANL, KCNSC, Sandia National Laboratories, Kirtland AFB, and AFRL Space Vehicles Directorate. A source told the Daily Mail: "That entire mission runs out of Kirtland Air Force Base."

Methodology note

The author explicitly flags the Texas sharpshooter problem: the cluster was noticed first, then the population boundary was drawn around it. The honest read is "this warrants investigation," not "this is proven." The assumed missing-persons rate for stably employed older professionals is 0.75 per 100,000 per year. If the true rate is 2–3× higher, the signal weakens — but arguing that senior cleared defense workers go missing at triple the normal rate is a hard case to make.

The murders in the broader list (Grillmair, Loureiro) are within statistical noise: 2 observed vs ~1.3 expected. The murders are not the anomaly. The disappearances are.

The corporate chain of custody

Mondaloy's trade secrets have passed through seven corporate owners in thirty years. The current transaction raises specific regulatory questions.

2005Ruby Acq. / UTC ($700M)

The CFIUS gap

The L3Harris 10-K filed February 12, 2026 does not mention CFIUS — the Committee on Foreign Investment in the United States — in relation to the AE Industrial transaction. Not once. Not in any other SEC filing between December 2025 and March 2026.

CFIUS is the federal body that must review any foreign investment in critical American defense technology. Rocket propulsion alloys are regulated under ITAR. AE Industrial Partners is backed by unnamed sovereign wealth fund investors.

Three possible explanations: (1) CFIUS reviewed and L3Harris failed to disclose — an SEC violation. (2) The deal was structured to avoid review thresholds — technically legal but exactly what the 2018 CFIUS reform law was meant to close. (3) Nobody filed and CFIUS didn't initiate review on its own — a regulatory failure. One of these three must be true. All three are findings. Documented

The deletion pattern

Four items discussing the Reza memorial or phone evidence were removed across four platforms by different apparent actors.

Find A Grave
Memorial for Reza created June 26, 2025, listing death date and "green burial" while helicopters were still searching. Later deleted. Account "lillian" went inactive.
Memorial ID 284387277
Substack
Entire publication "Sub Intelligence Agency" deleted within ~2 weeks of launching. Had published an article about the Reza memorial anomaly.
Post ID p-192335136
Facebook (SAR)
Montrose Search and Rescue post acknowledging that "technical experts" obtained cell phone forensic data in the Reza case. Deleted.
Platform: Facebook
Facebook (Group)
Civilian search group "Find Monica" deleted after a member posted a theory about phone tampering.
Platform: Facebook

Unanswered questions

Specific, checkable questions that could be resolved with public records, FOIA requests, or subpoena power.

01
Who created the Find A Grave memorial for Monica Reza four days into the search, and on what basis was "green burial" listed when no body had been recovered?
The memorial ID and creator username ("lillian") are on record with Ancestry.com. An email and IP address exist in their database.
02
What do the cell phone forensics obtained in the Reza case show?
Montrose SAR acknowledged that "technical experts" obtained cell phone forensic data. That post was deleted. The data has never been publicly released.
03
Did Judge Abbasi routinely release defendants with loaded-weapon charges on their own recognizance?
Re: Grillmair case. Freddy Snyder was released OR after arrest with a loaded unregistered rifle on the victim's property. 12 months of comparable decisions from PACER would answer this.
04
Did Freddy Snyder actually complete the hunter safety course cited in the dismissal of his charges?
Charges dismissed under CA Penal Code 1385 eleven days before Grillmair's murder. California Department of Fish and Wildlife maintains provider records.
05
Why did KCNSC run a counterintelligence-style search of Steven Garcia's work computers within days of his disappearance, and then say nothing publicly for eight months?
This is not an HR response. It is a response to potential data exfiltration by a cleared individual. KCNSC and DOE declined to comment.
06
Why do L3Harris's SEC filings related to the $845M Rocketdyne transaction never mention CFIUS?
A PE firm backed by unnamed sovereign wealth funds acquiring ITAR-controlled rocket propulsion technology should trigger mandatory CFIUS review.
07
Why was Anthony Chavez's missing person report delayed by four days?
A 30-year LANL engineer vanishes from a small, heavily monitored town, and only the local PD investigates. No FBI. No DOE. No state police.
08
Can the United States still produce Mondaloy?
The metallurgist who understood the crystallography is dead. The engineer who scaled it for production is missing. The general who greenlit the programs is missing. The patents are expired. The answer to this question determines whether the US has a capability gap in national security rocket propulsion.
