Brazil launches S+100 ballistic missile program to strengthen Astros II MLRS strike capability.

The Brazilian Army has launched the S+100 tactical ballistic missile program to enhance the long-range strike capability of its Astros II MLRS, reinforcing Brazil’s ability to deliver high-speed precision fires against strategic targets.

Developed under the leadership of the Army’s Logistics Command and Department of Science and Technology in partnership with Avibras, the program ensures full compatibility with existing Astros launchers, directly strengthening operational readiness and deep-strike effectiveness. The initiative is tied to Avibras’ financial restructuring and the recovery of Brazil’s missile industrial base, with development building on prior S-80 efforts.

As reported by Estadão on April 7, 2026, the development of the S+100 tactical ballistic missile by the Brazilian Army coincided with the financial restructuring of Avibras, linking a new S+100 program to the recovery of the country’s main missile manufacturer and to ongoing efforts to sustain the Astros-based strike architecture. The Army is advancing the S+100 through its Logistics Command and Department of Science and Technology, with the requirement that the system remains compatible with Astros launchers and builds on prior work conducted under the S-80 program. This development takes place while Avibras resumes operations after entering judicial recovery in March 2022 with declared debts of R$394 million, reflecting a direct connection between industrial solvency and the continuation of missile programs considered essential for operational capability.

The restructuring of Avibras is supported by a R$300 million private funding package coordinated by Fundo Brasil Crédito, with Joesley Batista participating as a principal financial contributor, alongside other investors, including at least one bank and fund stakeholders Raul Ortuzar and Thiago Osório. The same fund became the company’s main creditor after acquiring a R$93 million claim in August 2024 and subsequently proposed an alternative recovery plan approved by creditors and judicial authorities, leading to the creation of a new corporate entity capitalized with R$2.5 billion in December 2025. The initial restructuring model anticipated an additional R$300 million in public financing from Finep, BNDES, or the PAC, but production is scheduled to restart in May without waiting for these resources, indicating a decision to prioritize operational restart over full financial closure.

Ownership considerations played a decisive role in shaping the outcome, as the Armed Forces opposed the transfer of Avibras to foreign control during a period when companies such as Norinco, DefendTex, and Black Storm Military Industries expressed acquisition interest between 2024 and 2025. The decision to maintain domestic ownership preserved control over intellectual property, production capacity, and engineering expertise tied to missile systems, while also responding to pressure from political actors who considered the company essential for national defense. This approach reflects a policy choice to prevent external dependency in a sector where only a limited number of countries maintain full-cycle missile development and production capabilities.

The Astros system remains the central element of Brazil’s missile infrastructure, providing a modular launcher capable of firing rockets and missiles across a range spectrum extending from 30 km to 300 km, and currently deployed in multiple configurations, including coastal defense. Its design incorporates a universal launcher module compatible with different calibers between 127 mm and 450 mm, allowing integration of new munitions without redesigning the launch vehicle. The system has been exported to several countries and remains in active use, supporting both domestic requirements and international contracts, while serving as the baseline interface for new missile programs, including the MTC-300 and S+100.

The MTC-300 cruise missile is approaching completion, with 90% of development finalized and a final firing campaign pending, representing a system designed for a range of up to 300 km with subsonic speed near Mach 0.85 and a warhead capacity between 200 kg and 500 kg. The missile uses a two-stage propulsion configuration combining a solid-fuel booster and a turbojet engine, with guidance based on GPS and inertial navigation systems and an accuracy below 30 meters. Development has been ongoing since the early 2000s, with significant investment from the Army since 2012, and the system is intended for deployment on Astros, with additional variants under consideration for air launch and naval integration, extending its operational use beyond land-based applications.

The S+100 tactical ballistic missile program represents a separate capability track focused on higher-speed trajectories and different engagement profiles compared to cruise missiles, with interoperability requirements ensuring compatibility with existing Avibras systems and logistics chains. The program is managed internally by the Army through its science and logistics structures and is expected to leverage accumulated expertise from earlier missile projects, while also targeting external markets where demand exists for systems comparable to short-range ballistic missiles in the 300 km class. Funding for such programs is supported by Complementary Law 221, which allows up to R$30 billion in defense-related expenditures to be excluded from fiscal limits through 2031, creating a budgetary framework for sustained investment.

Missile integration is extending across services, with the Air Force examining an air-launched version of the MTC-300 under the MICLA-BR program for future use on the F-39 Gripen, while the Navy has already integrated Astros into coastal defense units equipped with the MANSUP anti-ship missile. The MANSUP currently has a range of 70 km, with an extended version projected to reach 200 km, compared to the 300 km class of the MTC-300, creating a layered set of capabilities across maritime and land domains. This structure supports coordinated operations across services, with shared launch infrastructure and overlapping missile families reducing integration complexity and enabling distributed deployment across different operational environments.

The industrial recovery process is directly tied to workforce and production metrics, with Avibras employing 80 personnel prior to restarting operations and planning to increase to 200 employees in May, 500 in June, and more than 1,000 as new orders are secured. The company has reactivated procurement and human resources functions and preserved production lines, information systems, and intellectual property throughout the recovery process, while resolving a labor dispute lasting 1,280 days through an agreement to pay R$230 million in liabilities to 1,400 former employees over four years. These measures enable the resumption of production and align industrial output with anticipated defense procurement linked to missile programs, ensuring that financial restructuring translates into sustained manufacturing capacity.
