Long Wall

Produces hypersonic testbeds and defense interceptors

Overview

Long Wall repurposes its launch heritage to serve U.S. defense needs, building deployable space and missile-defense testing tools for the government. Its RSX is a hypersonic flight-test vehicle used as a test bed and threat-replication target, Ironwood is a containerized ground system for responsive launch, and Cyclops is a surface-launched interceptor designed to engage missiles in midflight. Unlike rivals pursuing commercial satellite launches, Long Wall focuses on U.S.-made defense hardware and offers an integrated set of launch/test and interception capabilities to shorten timelines and reduce costs. Its goal is to strengthen national security by providing ready-to-use, deployable defense testing and interception solutions for government customers.

Simplify's take

What believers are saying

  • June 2026 Pentagon hypersonic activity validates demand for responsive test and interceptor systems.
  • Long Wall raised fresh capital in July 2026, extending runway to 2027 programs.
  • The 2025 rebrand aligned hiring and facilities around defense, improving government procurement fit.

What critics are saying

  • No public Cyclops contract was disclosed by December 2025, leaving demand unproven.
  • ABL's 2023 launch failure and 2024 fire destroyed credibility before the defense pivot.
  • SpaceX and Lockheed Martin dominate contracts; Long Wall risks becoming a niche supplier.

What makes Long Wall unique

  • Long Wall's 2025 pivot repurposed RSX and Ironwood for missile defense, not launch.
  • Cyclops targets exoatmospheric interceptors with containerized launch, aiming at low-cost magazine depth.
  • Its 160,000-plus square feet can produce over one hundred Cyclops rounds yearly.

MDA awards $75M to Long Wall for low-cost, midcourse interceptor testing.

MDA awards $75M to Long Wall for low-cost, midcourse interceptor testing. 23 October 2026, 03:36 published 1min, 36sc WASHINGTON - The Missile Defense Agency (MDA) has awarded California-based startup Long Wall $75 million to complete testing of its self-funded Cyclops low-cost interceptor designed to strike enemy missiles midway through their flight, the company announced today. "I think it's a first of its kind award in long-range missile defense, and a substantive commitment," Long Wall Founder Dan Piedmont told Breaking Defense. Long Wall officially was established in February 2025 as a rebranding of the former launch firm ABL Space Systems, with a narrow focus on missile defense. The company unveiled the liquid-fueled Cyclops in December 2025, touting it as the first exo-atmospheric interceptor designed to be mass produced. Long Wall's website explains that the interceptor can fit in a shipping container, and thus be launched either from the ground or from a sea-based platform. In addition, the company stresses it is largely using commercial off-the-shelf components and technology, including 3D printing, in Cyclops production. According to the press release, the company over the past two years has invested its own capital in developing the interceptor and will continue to do so as part of the MDA contract. "Throughout the period of performance, Long Wall will invest an additional $75 million at private expense to continue Cyclops design and development," the release said. The company referred a question about the duration of the contract to MDA, which did not respond by press time to a query from Breaking Defense. Decentralized Embodied Collaborative intelligence enables better reconnaissance, logistics and combat capabilities. While the Cyclops is a midcourse interceptor like the currently deployed Ground-Based Interceptor built by Northrop Grumman, MDA also is exploring low-cost options for destroying enemy missiles after they have reentered the atmosphere and are closer to their targets. The agency in August awarded X-Bow Systems a contract work almost $11 million to flight test its solid fuel low-cost interceptor as a potential alternative to the Army's arsenal of Patriot missiles.

MDA awards Long Wall $75M to complete flight testing of low-cost Cyclops interceptor

The Missile Defense Agency (MDA) has awarded California-based startup Long Wall $75 million to complete flight testing of Cyclops, its low-cost midcourse defence interceptor, the company said Thursday. Long Wall began developing Cyclops in 2024 and announced it in late 2025. The system is a surface-launched, mass-producible exo-atmospheric interceptor. At the time, the company said it aimed to reduce limits on where Cyclops can be fired, giving the military more flexibility.

Long Wall announces $75 million award from the Missile Defense Agency for Cyclops low-cost interceptor.

Long Wall announces $75 million award from the Missile Defense Agency for Cyclops low-cost interceptor. Long Wall has announced a $75 million award from the Missile Defense Agency to complete flight testing of the Cyclops low-cost interceptor. Long Wall began development of Cyclops in 2024 and announced the product in December of last year. "Demand for interceptors has surged, while low production capacity and high unit costs remain major challenges to replenish expanded magazine depth," explains Dan Piemont, Co-Founder and CEO of Long Wall. "We bring a clean sheet design and a new approach to the table. With Cyclops, Long Wall is building for the current and future operational environment." Throughout the period of performance, Long Wall will invest an additional $75 million at private expense to continue Cyclops design and development. "We spent the last two years investing our own capital to design and test Cyclops based on our perception of escalating global threats," Piemont continues. "We will continue investing alongside the MDA to ensure the U.S. maintains a qualitative and quantitative edge over those who threaten us." Long Wall is executing the Cyclops program with mature, highly verticalized development, test, and production infrastructure spanning over 180,000 sqft and 100 acres across three major facilities. "As technologists, there has never been a better time to make a mass-producible interceptor in this class," says Harry O'Hanley, Long Wall Co-Founder, Chairman, and President. "We have some pretty incredible tools at our disposal - from the latest GPUs to breakthroughs in optics and propulsion manufacturing - and we have the opportunity to take advantage of it all from day one and deliver for the MDA." About Long Wall Long Wall's mission is to accelerate missile defense. Long Wall is developing the Cyclops low-cost interceptor, containerized launchers, and deployable targets. The company is headquartered in Long Beach, California, with operations across California, Alaska, and Alabama. The growing Long Wall team ranges from talented new grads to the most seasoned national technical experts in missile defense. View open roles here:
