Rocket Lab Completes Successful First Hot Fire of Archimedes Engine for Neutron Rocket

Rhea-AI Summary

Rocket Lab USA, Inc. (Nasdaq: RKLB) has successfully completed the first hot fire test of its new Archimedes engine for the Neutron rocket. The test, conducted at NASA's Stennis Space Center in August 2024, achieved 102% power and anchored the engine's design ahead of Neutron's first flight scheduled for mid-2025. The Archimedes engine, designed for rapid reusability, will power both stages of the Neutron rocket and is capable of producing up to 165,000 pounds of thrust per engine.

Neutron is Rocket Lab's new reusable medium-lift rocket, designed to deliver up to 13,000 kilograms of payload to space. It features carbon composite structures and an innovative upper stage for complex satellite deployments, including mega-constellations. With this milestone achieved, Rocket Lab is moving into full production of flight engines and finalizing the qualification test campaign.

Aerospace Engineer

The successful hot fire test of Rocket Lab's Archimedes engine marks a significant milestone in the development of the Neutron rocket. Achieving 102% power and completing the test in just a couple of years demonstrates impressive engineering efficiency. The focus on producing a flight-ready engine rather than a prototype is a strategic advantage, potentially accelerating Neutron's path to market.

The Archimedes engine's design, featuring oxidizer-rich staged combustion and the use of liquid oxygen and LNG propellants, suggests a strong emphasis on reusability and performance. The 3D printing of critical components could lead to cost reductions and manufacturing flexibility. With nine engines producing 1,450,000 lbf of thrust, Neutron appears well-positioned to compete in the medium-lift launch market.

Financial Analyst

Rocket Lab's progress with the Archimedes engine and Neutron rocket development could have positive implications for the company's financial outlook. The potential to bring Neutron to market by mid-2025, faster than competitors, may give Rocket Lab a first-mover advantage in the evolving medium-lift launch sector.

The focus on reusability and cost-effectiveness in Neutron's design could lead to improved profit margins and competitiveness in pricing. Additionally, the versatility of Neutron for various mission types, including mega-constellation deployments, positions Rocket Lab to capture a larger market share in the growing satellite launch industry. However, investors should monitor development costs and potential delays, as these could impact the company's near-term financial performance.

Market Research Analyst

The medium-lift launch market is becoming increasingly competitive and Rocket Lab's progress with Neutron could significantly alter the landscape. The 13,000 kg payload capacity puts Neutron in direct competition with established players like SpaceX's Falcon 9 and emerging vehicles like Blue Origin's New Glenn.

Rocket Lab's emphasis on rapid reusability and innovative design features like the carbon composite structures could differentiate Neutron in the market. The ability to serve both commercial and government customers, particularly in deploying satellite mega-constellations, aligns well with projected market demand. If Rocket Lab can maintain its accelerated development timeline, it may capture a significant portion of the growing medium-lift launch market before some competitors enter the field.

LONG BEACH, Calif.--(BUSINESS WIRE)-- Rocket Lab USA, Inc. (Nasdaq: RKLB) (“Rocket Lab” or “the Company”), a global leader in launch services and space systems, today announced it has successfully hot fired its new rocket engine Archimedes for the first time, reaching a critical technical milestone toward first launch of the Company’s new medium-lift rocket, Neutron.

Rocket Lab’s engineers completed the hot fire test at the Company’s Engine Test Complex within NASA’s Stennis Space Center in Hancock County, Mississippi, in August 2024. Archimedes performed well and ticked off several key test objectives, including reaching 102% power, anchoring the engine’s design ahead of Neutron’s first flight scheduled for mid-2025 – a schedule that would make Neutron the fastest a commercially developed medium-class launch vehicle has been brought to market. With the hot fire complete and full qualification campaign now underway, the Rocket Lab team is moving into full production of flight engines.

Rocket Lab founder and CEO, Sir Peter Beck, says: “Hot firing Archimedes is a major development milestone for Neutron and our team has done it on an accelerated timeline. Taking a new staged combustion liquid rocket engine from cleansheet design to hot fire in just a couple of years is industry-leading stuff. We’ve been consistently impressed with the performance of Archimedes in test, including with this hot fire, so with this critical milestone completed, we move into production of flight engines confidently and begin to close out the qualification test campaign in parallel to really hone performance for launch next year. From the day we started designing Archimedes we focused on delivering a flight engine, rather than an early-stage prototype destined for multiple reworks and adjustments, so it's gratifying to see this strategy bear fruit.”

The Archimedes engine will power Rocket Lab’s new reusable medium-lift rocket Neutron, a next-generation challenger to deliver a cost-effective, reliable, and responsive launch service for commercial and government missions. The advanced design of Neutron includes carbon composite for all of the rocket’s major structures and an innovative upper stage that enables high-performance for complex satellite deployments, including the deployment of satellite mega-constellations.

The Archimedes engine is an oxidizer rich staged combustion cycle engine that will power the reusable first stage of Neutron and the new rocket’s second stage that is designed to carry up to 13,000 kilograms of payload to space. Capable of producing up to 165,000 (733 kilonewtons) pounds of thrust per engine, Archimedes operates at lower stress levels than other rocket engines to enable rapid and reliable reusability. The combined thrust of nine Archimedes engines for Neutron’s first stage is designed to reach 1,450,000 lbf total. Archimedes uses a cryogenic propellant mix of liquid oxygen and LNG to enable higher reusability and performance, and many of its critical components are 3D printed including Archimedes’ turbo pump housings, pre-burner and main chamber components, valve housings, and engine structural components.

Production of the Archimedes engines takes place at Rocket Lab’s Engine Development Complex in Long Beach, California.
