Antares Industries Secures $96 Million Series B to Accelerate Microreactor Deployment

Antares Industries, a defense-first nuclear engineering company, announced on December 2, 2025, that it has raised $96 million in Series B funding. The round was led by Shine Capital, with participation from Alt Capital, Caffeinated Capital, FiftyThree Stations, and Industrious. This latest injection of capital brings the company’s total funding to over $130 million, following a $30 million Series A raised in late 2024.

According to the company’s official statement, the funding consists of $71 million in equity and $25 million in debt. The capital is specifically earmarked to transition the company from design to physical production, with a focus on deploying the R1 microreactor. Antares aims to deliver resilient, portable power for defense and space applications, positioning itself as the “engineering prime of strategic energy.”

The R1 Microreactor: Technology and Design

The core of the Antares value proposition is the R1, a compact microreactor designed to operate autonomously for over three years without refueling. Unlike traditional gigawatt-scale nuclear plants intended for civilian power grids, the R1 is engineered for mobility and resilience in hostile environments.

Based on technical specifications released by the company, the R1 features a power output ranging from 100 kilowatts (kWe) to 1 megawatt (MWe). The system utilizes TRISO (Tristructural Isotropic) particle fuel, which is widely regarded in the industry for its robustness and resistance to meltdowns. The fuel consists of uranium kernels encased in layers of carbon and ceramics, providing a high degree of passive safety.

For cooling, the R1 employs sodium heat pipes. This “solid-state” cooling method eliminates the need for moving pumps, relying instead on passive physics to transfer heat. The system uses a Closed Brayton Cycle, where heated nitrogen gas spins a turbine to generate electricity. This design allows the reactor to be transported via standard logistics networks, including trucks and cargo aircraft, without requiring a water source for cooling.

Strategic Timeline and Regulatory Pathway

Antares Industries has outlined an aggressive timeline for hardware validation, leveraging recent shifts in U.S. energy policy. The company plans to conduct a “Mark-0” low-power demonstration at the Idaho National Laboratory (INL) in 2026. This test is intended to validate reactor physics and control systems.

Following the Mark-0 demo, Antares aims to construct and test the “Mark-1” prototype, a full-power, electricity-producing unit, at the same INL facility in 2027. Commercial deployment of production units is targeted for 2028.

Leveraging Executive Order 14301

A critical component of this accelerated timeline is the company’s utilization of Executive Order 14301, “Reforming Nuclear Reactor Testing at the Department of Energy,” issued in May 2025. This order allows companies to bypass the lengthy traditional Nuclear Regulatory Commission (NRC) licensing process for initial testing phases, opting instead for expedited Department of Energy (DOE) authorization.

In a statement regarding the company’s operational philosophy, Antares CEO Jordan Bramble emphasized the necessity of speed in the current geopolitical climate.

“This capital allows us to move with the speed and discipline required to deliver something America hasn’t done in a very long time: design, build, and test nuclear reactors within a few years, not decades.”

Defense-First Market Strategy

Antares has adopted a strategy focused on securing government contracts to validate its technology before entering broader commercial markets. The company views the U.S. military as the “first moving customer” for advanced nuclear capabilities due to the strategic risks posed by energy scarcity in conflict zones.

The company is currently competing for the U.S. Army’s Project JANUS, a program designed to deploy microreactors to army bases to ensure energy resilience. Additionally, Antares has secured contracts with the Air Force, Space Force, and the Defense Innovation Unit (DIU) to power mission-critical assets such as radar systems and directed energy weapons.

Beyond terrestrial defense, Antares is aligning its technology with NASA’s Fission Surface Power goals, which aim to land a 100-kWe reactor on the Moon by 2030 to support long-term lunar operations.

AirPro News Analysis

The successful Series B raise by Antares Industries highlights a significant pivot in the nuclear sector: the move from “paper reactors” to hardware-rich development cycles. For decades, the nuclear industry has been stifled by high regulatory hurdles that forced companies to spend years on modeling before breaking ground. The utilization of Executive Order 14301 suggests that the U.S. government is actively clearing these hurdles to treat energy independence as a national security imperative.

Furthermore, the involvement of Shine Capital and other venture firms signals a growing investor appetite for “deep tech” hardware that serves dual-use purposes (defense and commercial). By targeting the Department of Defense as an anchor customer, Antares mitigates the market risk typically associated with advanced energy startups, securing revenue streams while the commercial regulatory landscape catches up.

U.S. Customs and Border Protection Air and Marine Operations (CBP AMO) has finalized a contract to acquire 10 additional Airbus H125 helicopters, expanding a fleet modernization effort that relies heavily on the single-engine platform for border security and law enforcement missions.

In a press release issued on July 7, 2026, Airbus confirmed the agreement, which reinforces a three-decade relationship between the federal agency and the aerospace manufacturer. The new helicopters will be assembled at the Airbus Helicopters production facility in Columbus, Mississippi.

Expanding the airborne law enforcement fleet

The latest acquisition builds upon a previous order placed in August 2020, when CBP AMO contracted for 16 H125 helicopters to upgrade its aging rotary-wing assets. The agency currently operates a total fleet of more than 240 aircraft, which includes over 100 helicopters from the Airbus H120 and H125 families delivered over the past 30 years.

The H125, formerly known as the Eurocopter AS350, is utilized by CBP AMO for a variety of demanding flight profiles, including border surveillance, suspect pursuit, and general public safety operations across the United States.

Bart Reijnen, Head of the North America Region for Airbus Helicopters, stated that the expansion “underscores the long-standing collaboration” between the manufacturer and the federal agency. He added that the selection highlights the trust placed in the H125 to execute critical public safety missions under demanding conditions, with Airbus committing to provide comprehensive services to maintain mission readiness.

Virtual reality integration for pilot training

As CBP AMO increases its H125 inventory, the agency is simultaneously overhauling how it trains the personnel who fly them. In November 2025, CBP became the first federal law enforcement agency and the first branch of the U.S. Department of Homeland Security (DHS) to integrate virtual reality into its aerial training program.

According to reporting by FLYING Magazine, the agency awarded a contract to adopt an FAA-qualified Airbus H125 virtual reality flight simulator developed by Loft Dynamics. The simulator is being installed at the CBP AMO training center in Oklahoma City, where it will be used to train the agency’s roster of more than 600 pilots.

Published

on

The European Commission has allocated approximately €25 million through the European Defence Fund to back a multinational consortium developing the propulsion architecture for Europe’s next generation of military helicopters.

Announced on June 11, 2026, at the ILA Berlin airshow, the Sovereign High-performance Architecture for Rotorcraft Propulsion (SHARP) project brings together 25 partners from 12 European countries. According to a joint press release from Safran Helicopter Engines, MTU Aero Engines, and Avio Aero, the initiative will establish the technological foundation for the European Next Generation Helicopter Engine (ENGHE), which is targeted to enter service in 2040.

Addressing an aging military rotorcraft fleet

The SHARP initiative aligns with broader European defense goals to replace a rapidly aging fleet of military aircraft under the Next Generation Rotorcraft Capability (NGRC) and European Next Generation Rotorcraft Technologies (ENGRT) programs. The current European inventory includes approximately 1,800 transport helicopters and 600 combat helicopters, which currently average 20 years of age. By the 2040s, many of these aircraft will have been in service for over 50 years.

“In light of a continuously aging European fleet of military helicopters the need is obvious: From 2040 onwards, a large proportion of these rotorcraft will have to be replaced,” said Dr. Ottmar Pfänder, Chief Program Officer at MTU Aero Engines. “We joined forces across the continent to underline the importance of this technology program. It will further reinforce European sovereignty and strengthen the European supply chain.”

The funding will be used to develop scalable technological building blocks that can be adapted to various weight classes and mission profiles required by future European armed forces.

Collaborative framework and European sovereignty

The SHARP project builds upon the foundation of the EUropean Military Rotorcraft Engine Alliance (EURA), a 50/50 joint venture established in July 2024 between Safran Helicopter Engines and MTU Aero Engines specifically to develop the ENGHE. The consortium has now expanded to include Avio Aero, broadening the industrial base tasked with designing the new powerplant.

Safran Helicopter Engines CEO Cédric Goubet stated that the funding demonstrates Europe’s commitment to self-reliance and technological sovereignty for future military platforms, thanking the European Union and participating nations for their confidence in the consortium’s capabilities.

“SHARP marks an important milestone in the journey toward Europe’s next-generation rotorcraft engine and reinforces the value of collaboration in developing sovereign, high-performance propulsion technologies,” said Riccardo Procacci, CEO of Avio Aero. “We are proud to partner with EURA on this initiative, contributing within a fully European framework while leveraging Avio Aero’s well-established expertise and know-how.”

EURA CEO Wolfgang Gärtner confirmed that the joint venture is prepared to coordinate the multinational team to provide modern technologies to European forces.

AirPro News analysis

The €25 million European Defence Fund grant represents a critical early step in aligning Europe’s fragmented defense aerospace sector behind a single rotorcraft propulsion program. By formalizing the SHARP consortium now, the European Union is actively working to prevent the development of competing, incompatible national engine programs that have historically complicated European defense procurement and increased long-term maintenance costs. We view the inclusion of Avio Aero alongside the EURA joint venture as a strong indicator that the ENGHE program is successfully consolidating the continent’s primary propulsion manufacturers ahead of the 2040 target.
