Long Wall Cyclops

History

Long Wall, a California-based missile defense company, was established in February 2025 as a rebranding of the former launch firm ABL Space Systems. The company began developing the Cyclops interceptor in 2024 and unveiled the system in December 2025. In October 2026, the Missile Defense Agency (MDA) awarded Long Wall $75 million to complete flight testing of the interceptor.

Design

Cyclops is a surface-launched, liquid-fueled, exoatmospheric midcourse interceptor, distinct from the Ground-Based Interceptor built by Northrop Grumman. The kill vehicle neutralizes threats via hit-to-kill impact. Long Wall describes a containerized launch station that can be deployed on bare ground or a ship deck and transported in a shipping container. The company states it is using commercial off-the-shelf components and 3D printing in production. Long Wall claims Cyclops is the first interceptor developed from a clean sheet for mass production and states its facilities can produce over one hundred rounds per year.

Program status

The MDA award funds the flight-testing phase. Long Wall will invest an additional $75 million at private expense to continue Cyclops design and development throughout the period of performance. The MDA has not publicly confirmed the duration of the contract.
