The MLV is an evolutionary successor to Northrop Grumman’s Antares launch vehicle, which has a proven track record of successful missions to the International Space Station. The new vehicle retains many of the flight-proven systems from the Antares program, ensuring a high level of reliability and performance. However, the MLV also incorporates significant upgrades to enhance its capabilities, including a more powerful vacuum-optimized second stage engine and an industry-standard 5-meter-class fairing that can be customized to accommodate a variety of payload configurations and mission requirements.
Antares Heritage
The Antares rocket, developed and operated by Northrop Grumman, has been a workhorse for delivering cargo to the International Space Station. With its proven reliability and performance, the Antares has set the foundation for the development of the MLV. By leveraging the successes and lessons learned from the Antares program, Northrop Grumman and Firefly Aerospace are well-positioned to create a launch vehicle that builds upon this legacy while introducing cutting-edge technologies and design improvements.
Enhanced Capabilities
The MLV boasts several key enhancements that set it apart from its predecessor. The rocket’s second stage features a powerful, vacuum-optimized engine that provides increased thrust and efficiency, enabling the MLV to deliver heavier payloads to a wider range of orbits. Additionally, the MLV’s 5-meter-class fairing, which is larger than that of the Antares, allows for greater flexibility in accommodating diverse payload sizes and configurations. This adaptability makes the MLV an attractive option for a broad spectrum of customers, from commercial satellite operators to government and military entities.
Innovative Technologies for Improved Performance

In addition to the heritage systems from the Antares program, the MLV benefits from the integration of cutting-edge technologies developed by Firefly Aerospace. These include a patented tap-off cycle propulsion technology, which optimizes engine performance and efficiency, as well as advanced carbon composite structures that reduce the vehicle’s overall mass and cost while improving its strength and reliability. By combining these innovative technologies with Northrop Grumman’s extensive experience in launch vehicle design and operations, the MLV is poised to set a new standard in the medium-lift launch market.
Tap-Off Cycle Propulsion
Firefly Aerospace’s patented tap-off cycle propulsion technology is a key innovation that sets the MLV apart from other launch vehicles in its class. This advanced propulsion system optimizes engine performance by efficiently utilizing the combustion gases generated during the rocket’s operation. By tapping off a portion of these gases and using them to drive the engine’s turbopumps, the tap-off cycle allows for a more compact and lightweight design while maintaining high levels of thrust and efficiency. This technology not only enhances the MLV’s performance but also contributes to its overall cost-effectiveness.
Advanced Composite Structures
Another critical aspect of the MLV’s design is the use of advanced carbon composite structures, which offer several advantages over traditional materials. These lightweight yet strong composites significantly reduce the rocket’s dry mass, allowing for increased payload capacity and improved fuel efficiency. Additionally, the use of composites enables a more streamlined manufacturing process, as these materials can be molded into complex shapes with fewer parts and joints. This simplification not only reduces production costs but also enhances the rocket’s reliability by minimizing potential points of failure.
Versatile Launch Options
The MLV is designed to provide customers with flexible launch options to meet their specific needs. The vehicle will initially launch from the Mid-Atlantic Regional Spaceport on Wallops Island, Virginia, taking advantage of the existing infrastructure and range support services. However, the MLV is also designed to be compatible with additional launch ranges on both the east and west coasts of the United States, allowing customers to choose the most suitable launch site for their missions. This versatility enables the MLV to serve a broad range of customers and mission types, from commercial satellite deployments to government and military payloads.
Mid-Atlantic Regional Spaceport
The Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, Virginia, will serve as the primary launch site for the MLV. This strategically located facility offers several advantages, including its proximity to major East Coast cities and its ability to accommodate a wide range of launch azimuths. MARS has a proven track record of supporting successful launches, including those of the Antares rocket, and its existing infrastructure will be leveraged to support MLV operations. The spaceport’s experienced team and state-of-the-art facilities will ensure reliable and efficient launch services for MLV customers.
Expanding Launch Options
While MARS will be the initial launch site for the MLV, Northrop Grumman and Firefly Aerospace are committed to providing customers with a range of launch options to suit their specific requirements. The MLV is being designed to be compatible with additional launch ranges on both the East and West Coasts of the United States. This flexibility will allow customers to select the most appropriate launch site based on factors such as orbital inclination, payload mass, and mission timeline. By offering a choice of launch locations, the MLV will be able to serve a diverse customer base and adapt to the evolving needs of the space industry.
Serving Diverse Markets
The MLV is poised to serve a wide array of markets, including commercial, civil, national security, and international customers. Its competitive pricing and flexible launch options make it an attractive choice for satellite operators, research institutions, and government agencies seeking reliable and cost-effective access to space.

The commercial space sector has experienced significant growth in recent years, with an increasing number of companies developing and launching satellites for various applications, such as telecommunications, Earth observation, and navigation. The MLV’s payload capacity and adaptable fairing design make it well-suited to meet the diverse needs of commercial customers. By offering competitive pricing and flexible launch options, the MLV will help foster innovation and growth in the commercial space industry.
Civil and Scientific Missions
The MLV’s capabilities also make it an ideal platform for civil and scientific missions. Government agencies and research institutions often require reliable and cost-effective access to space to conduct experiments, gather data, and advance our understanding of the Earth and the universe. The MLV’s ability to deliver payloads to a variety of orbits and its compatibility with multiple launch sites will enable these organizations to pursue their scientific objectives with greater flexibility and efficiency.
National Security Applications
In addition to commercial and civil markets, the MLV is expected to play a significant role in supporting national security space missions. The increasing importance of space-based assets for military and intelligence operations has driven demand for reliable and secure launch services. The MLV’s U.S.-based design and manufacturing, coupled with its robust performance and flexible launch options, make it an attractive choice for national security customers seeking to protect sensitive payloads and ensure mission success.
