Dino Mavrookas: America Needs to Build Ships Again
China built over 1,000 commercial ships last year versus five large ocean-going vessels in the US, while China holds 57% of global shipbuilding capacity. Port Alpha’s $3 billion project targets autonomous container ships, tankers, and roll-on/roll-off vessels: simpler designs could enable scale and lower costs, but only 1% of the roughly $1 trillion FY26 Department of War budget went to autonomy.

- Dino Mavrookas frames US naval decline in one ratio: “China outbuilds the US 230 to one,” with the biggest discrepancy in commercial shipbuilding — China built over 1,000 commercial ships last year while the US built five large ocean-going commercial vessels, a figure he thinks was for 2024. The US fleet sits around 290 ships; Congress set a 355-ship statutory minimum in 2018, and in 2024 the Navy said it needed 381. The 30-year plan to get there would cost $1.2 trillion “if we can even execute as a country in the first place.”
- Despite a $1.5 trillion presidential budget request, maritime executive order, and SHIPS Act, only 1% of the roughly $1 trillion FY26 Department of War budget goes to autonomy — “that just gives you a sense of how far we actually have to go.” Mavrookas contrasts aircraft carriers that take 10+ years and whose cost jumped from the $13 billion he was quoting to the $19 billion the president cited last week, versus his view that Saronic’s autonomous ships could save taxpayers “hundreds of billions.”
- The Castellion partnership is his exhibit A for the new defense-tech operating model: Mavrookas and Castellion CEO Brian got on the phone, invested their own capital, and were “eight steps ahead by the time the government even came in.” The planned result is a containerized hypersonic missile test launch off the back of Marauder, an autonomous ship, “before the Navy completes its first test of a hypersonic missile off of a manned vessel.”
- On new primes, Mavrookas won’t dodge: five to 10 “really big, impactful companies” will scale over the next five to 10 years, reversing the consolidation that took roughly 55–60 primes down to five. He’s explicit this complements rather than replaces legacy: “we need the primes that exist today,” just alongside companies building what they can’t.
- Commercial shipbuilding is the strategic foundation, not a side business: China holds 57% of global shipbuilding capacity and, he says, subsidizes construction, raw materials, labor, and financing. South Korea and Japan, the next two largest shipbuilders, get a lot of their commercial modules and labor from China. If conflict comes in the Taiwan Strait, “China can outproduce the rest of the world in terms of ships” — and without tankers and roll-on/roll-off vessels, “we actually don’t have the ships to resupply our force.”
- Molly describes the just-announced $3 billion Port Alpha project as the scale bet: 10,000 jobs over 10 years and a $160 billion economic impact around Brownsville, Texas, while targeting autonomy for container ships, tankers, and roll-on/roll-off vessels. Mavrookas’s stated mechanism: autonomy means people are no longer required aboard, which “lets you simplify the design,” produce at scale, drive down costs, and open previously unserviceable markets.
- His “hottest take” is his whole thesis, delivered with full conviction: “not just the defense market, but the entire maritime industry is centered around autonomy.” Molly cites Saronic’s $9 billion valuation and $2.6 billion raised; Mavrookas says the team has grown to 1,800 people in four years and is building for that autonomy-centered maritime future.
Inside the Factory Building America’s Autonomous Navy
Saronic’s $9.25B valuation and $2.6B raised center its shipbuilding thesis on capacity, with Port Alpha’s $3.2B initial buildout adding 150,000 gross tons. An Austin line designed for 2,000 Corsairs annually combines hardware-software co-design, software reuse, and 25,000+ testing hours, but ocean reliability remains unresolved.

- Saronic ($2.6B raised, last valued at $9.25B) is betting that the answer to America’s shipbuilding collapse is capacity, not exquisite platforms. CEO Dino Mavrookas’s stark framing: China outbuilds the US “230 to one,” the naval fleet is shrinking, and the US holds “0.1% of global shipbuilding capacity — that’s a nonexistent industry.” His conclusion: “We’re gonna bring shipbuilding back in a way that we haven’t seen since World War II.”
- Port Alpha in Brownsville, Texas is the tradeable headline: a $3.2B investment on an initial 800-acre footprint — already the largest shipyard in the country — expandable past 4,000 acres. Initial buildout adds 150,000 gross tons of capacity, 1.5x the entire current US shipbuilding base of 100,000 gross tons, with a stated path to more than 2 million, 850-foot ships initially scaling to 1,200-foot “floating cities,” and 10,000+ jobs over 10 years.
- The Austin line can build 2,000 Corsairs per year — and Mavrookas stresses that controlling 2,000 boats is a separate challenge from building them. “It’s one thing to build 2,000 boats. It’s another thing to actually control 2,000 boats, and it’s software and autonomy that actually enables that.” The moat, in his telling, is hardware-software co-design, not either piece alone.
- Mavrookas says Corsairs are already in combat: a $392M Navy contract announced December 2025, and active use in the Straits of Hormuz — including the first-ever combat search and rescue by an autonomous system (two downed Apache pilots) and an offensive strike on an Iranian port that “took out an Iranian submarine.” For Mavrookas, a SEAL from 2004–2015, the rescue is personal: a 2005 helicopter was shot down trying to rescue trapped SEALs. “You might not always be able to do it with an autonomous system, but when you can, we absolutely should.”
- The product ladder is deliberately iterative: an $800 Amazon raft carrying $30K of electronics → Spyglass (6-ft all-electric jet ski) → Corsair (24 ft, 1,000 nm, 1,000 lb payload) → Mirage (52 ft, 15x larger volumetrically, 2,500 nm, 3,500 lb) → Marauder, a 180-ft fully autonomous ship. All-electric was tried but did not meet the military’s range and payload needs — “you just don’t get the range and the payload capacity that the military’s looking for” — and software reuse across platforms is what lets new hardware platforms launch fast.
- Workforce is the real shipbuilding bottleneck, and Saronic’s answer is design-for-manufacturability rather than waiting for skilled labor to reappear: “We’re building ships so that we can rebuild the workforce, not saying, ‘Oh, the workforce doesn’t exist, so we can’t build this ship.’” The Franklin, Louisiana yard — acquired as it was closing, workforce retained — went from 30 people to 300–400 in about a year.
- Notably, Mavrookas hedges on the top end: “I don’t know that we’ll ever build a traditional aircraft carrier” — the future Navy is a hybrid fleet, and Saronic’s lane is mass-scalable platforms plus commercial shipbuilding, the segment gutted by the 1981 subsidy removal and the 1993 Navy budget cut of 41%.
