I’ve never felt the importance of @traysartech mission more than I do today. Trump signed this deal because he understood the alternative. If the real goal was to eliminate Iran’s military capabilities, it would have required far more than airstrikes. It would have meant boots on the ground and operations deep inside the vast subterranean networks where much of Iran’s nuclear infrastructure, missile production, and strategic assets can survive. If you’re not willing to go all the way, it’s often better not to go halfway - especially against a regime willing to absorb enormous economic damage and loss of life while continuing to pursue its objectives. This deal does not mean peace to me. Unfortunately, I believe we will be dealing with this threat again in the coming years. That is the nature of ideological movements driven by Muslim fundamentalism - they rarely abandon their long-term ambitions. In the meantime, I believe it is our mission at Traysar, and hopefully the mission of many others, to work as hard and fast as possible so that the next time we face Iran or other adversaries we have technologies that can reach anywhere, access any underground stronghold, and turn subterranean infrastructure from a strategic advantage into a strategic weakness. Godspeed.

In continuation to my first post wanted to share more technical information about this and decoupling , and it’s strategic meaning : At the center of this geophysical and engineering field is the concept of cavity decoupling. How does it work? Rather than detonating an underground explosion directly within solid rock—which generates powerful seismic waves that are quickly detected worldwide—the explosion is conducted inside a massive underground cavity excavated in hard rock or a salt dome. The engineering principle is straightforward: the air and gases within the cavity absorb much of the blast pressure and thermal energy, significantly reducing the seismic energy transmitted into the surrounding rock. The result is a dramatically weaker seismic signature. Under favorable conditions, the measured seismic signal can be many times smaller than that of an equivalent explosion in solid rock, making a significant underground explosion appear much smaller to monitoring systems. What does this mean for the Subterra community? Physical concealment versus digital detection. The technological race underground is evolving along two parallel tracks: on one side, increasingly advanced excavation and isolation techniques designed to reduce acoustic, seismic, and other detectable signatures; on the other, increasingly sensitive sensors and sophisticated algorithms capable of detecting the faintest disturbances beneath the Earth’s surface. The underground as the next strategic domain. Nations such as China, Russia, and Iran recognize that in a world where the surface battlefield is becoming increasingly transparent, geological depth offers one of the few remaining advantages for survivability, concealment, and operational resilience. Anyone who believes the subterranean domain is limited to tactical tunnels is missing the bigger picture. The science, engineering, and technology being developed beneath the surface are shaping the next frontier of strategic competition.

China detaining a US seismologist over claims he was helping the US detect underground nuclear experiments done by N Korea , and probably to use his knowledge to hide hide their own. Subterra is not tactics it’s at the core of our national deterrence

Spend 10 minutes with @noah_schochet speaking passionately about big robots on the moon, and you just know he will make it happen
Noah Schochet@noah_schochet

Today, we’re announcing that we’ve raised $115 million in funding, including a $100M Series A led by @kleinerperkins. America has lost the ability to build, and we’re here to restore it. My co-founder, @NoahMcGuinn, and I left our jobs at @SpaceX , where we worked on programs including Starship, Starshield, and @Starlink, to build a company that will solve construction’s greatest challenges. Infrastructure is the foundation of civilization, and construction is the precursor to innovation. If America wants to build a brighter future for the next generation, we have to make it faster, cheaper, and safer to build. That’s where @TerraFirma_Inc comes in. We’re a new type of company, a robotic construction company that builds the full technology stack needed to deliver an order-of-magnitude improvement in one of the world’s oldest, largest, most important, but least efficient industries. We are building technology that expands what’s possible in construction on Earth, and then we'll use that same technology to build megastructures and colonies on the Moon and Mars. We’ve made tremendous progress over the past year, growing the company more than 10x in the last 12 months. We are performing projects across the world. By the end of October 2026, we are on track to operate 3 of the top 3 largest robotic construction fleets in the world, each on a different continent, bringing unprecedented speed, scale, and efficiency to some of the world’s most complex critical infrastructure projects. This funding will allow us to step on the gas and scale our manufacturing, software, operations, and construction deployments, including work on massive commercial and government contracts. We’re building the future of construction right here in Austin, Texas, and scaling it globally. If you want to be part of the team changing the world, now and on Mars, join us. Our Series A was led by Kleiner Perkins, with participation from Bain Capital Ventures, Glade Brook Capital Partners, BANNER VC, Saga Ventures, Trust Ventures, Definition, PEAK6, Magnetar Capital, and Ravelin Capital. Huge thanks to all of our angel investors, friends, and family who have helped and supported us throughout this journey. Apply here: jobs.ashbyhq.com/TerraFirma-Inc…

❗️❗️❗️Ukrainian forces executed a massive, highly coordinated bombardment campaign overnight, targeting the Armyansk district along the occupied left bank of the Kherson region. The complex joint operation was successfully carried out through the combined assets of Naval Aviation, Naval Unmanned Aviation, the National Guard's (NGU) elite "Lazarus Group," and the 34th "Venom" Unmanned Systems Center of the State Special Communications Service. The primary target was a sprawling, semi-underground Russian logistics hub containing vital command posts, specialized supply depots, and critical technological systems. To effectively penetrate the hardened, semi-subterranean installations, Ukrainian forces deployed a heavy wave of oversized, high-payload kamikaze drones specifically designed for maximum structural destruction. According to official statements from the Armed Forces of Ukraine, the operation achieved complete success due to the prior systematic neutralization of Russian air defense networks across the entire sector. While specific operational details remain classified under tight security, Ukrainian commanders confirmed that Russian occupying forces have already sustained heavy casualties, with numerous personnel listed as missing in action, promising that explosive visual evidence from the strike will surface online shortly.

The interstate highway system had specific Military purpose! Logistics (+ backup airports) is CRITICAL to national defense. Today, in an era of cheap unmanned systems and ubiquitous overhead imagery we should consider a new UNDERGROUND national highway system.

@SpencerGuard is so right , think of it this way : if until now Subterra was a tool of a lesser adversary to survive the US overwhelming force - and it worked (Iran ) just imagine the meaning of a close to equivalent adversary with the same ability to stand protected by the US strikes. Also with Guam killers and more how do we protect are troops from these mass air attacks when stock piles become low ?
John Spencer@SpencerGuard

China investing in technology, research, and application in deep buried blasting projects. Surely only for civilian application (not). The U.S. needs to lead in the subterra domain. It is the future. @traysartech @anduriltech @PalmerLuckey @asherdigs nature.com/articles/s4159…

Very bittersweet feeling. Last day at SpaceX on Tuesday. On one hand I am excited for the opportunities that await, on the other hand, I am going to miss seeing all the people I’ve grown so close to over the years in the office every day. I am handing off engineering ownership of the pad webcast cams and the pad highspeed cinema cameras to a very capable team, and I await great results as they continue to develop these systems. I really do consider these cameras systems to be my babies, and I’m stoked to see them grow up from the sidelines. I am very excited to be joining @traysartech up in Austin in the coming weeks, and I am going to try my best to live up to the expectations of the incredible people there. I am taking this as a challenge to do engineering in a wildly different arena and learn from some uniquely experienced people that are trying to do some very hard things in the subterra domain. I am making a crazy life change that I never expected, but I know, no matter what, that I have a family in South Texas that believes in this bright future in the same way I do.

After our short-form podcast, me and @SpencerGuard realized there was too much we didn’t get to talk about and filmed a long-form version about the subterra domain. The best part is we got @traysartech principal engineer @GKGB0616 to share his technological insights. Enjoy.
John Spencer@SpencerGuard

Long form podcast digging deep into all parts of the "Subterra Domain." The challenges, opportunities, capabilities needed. All w/ @traysartech an impressive group of experts becoming the "go to" source for rethinking an under resourced domain of warfare. youtube.com/watch?v=8ywusQ…

Developments in the mining world , are also significant in the defense world , for example : “Aramine and sensmore are introducing an automated Aramine L140B Loader into underground production at Cemex’s Rüdersdorf limestone quarry in Germany, turning a proven underground machine into an autonomous production system for real operating conditions” When Iran purposely collapses entry ways to strategic Subterra facilities these approaches are the exact solution of gaining acsses without risking troops
