Chilean turbo-prop aircraft program brings together defense, industry, and national technology to expand military autonomy, reduce external dependency, and leverage the experience accumulated by ENAER with the T-40 Newen and the T-35 Pillán.
The Chilean Navy, the Chilean Air Force, and the National Aeronautics Company signed, in El Bosque, on June 11, 2026, the agreement that opens the Basic Investment and Engineering Study of the Multipurpose Turboprop System Project.
Known by the acronym STM, the initiative foresees a technical and economic evaluation of a future national turboprop aircraft, with complementary subsystems and the capacity to meet training, support, and operational mission demands of the Chilean Naval Aviation and Air Force.
Still in its initial phase, the project has not had final specifications disclosed but is part of an institutional strategy to reduce external dependency in a high-cost sector, where acquisition, integration, and maintenance usually involve international suppliers.

Chile evaluates a new stage for military aviation
Signed at the ENAER facilities, the agreement brought together representatives of the three involved institutions, including Vice Admiral César Delgado, Rear Admiral Luis Felipe Díaz, Aviation General Miguel Stange, and the executive director of the state aeronautics company, Henry Cleveland.
According to the design announced by the institutions, the study should evaluate technical, industrial, and financial conditions to develop a common platform capable of fulfilling different missions without each force needing to seek separate solutions in the international market.
The Chilean Navy reported that the agreement will allow for the analysis of the design, development, and manufacturing of a weapon system formed by a new turboprop aircraft and its associated systems, aimed at personnel training and multiple military tasks.
In this format, standardization can reduce costs throughout the aircraft’s life cycle, especially in training, maintenance, logistics, and components, should the project advance to the detailed engineering, prototyping, and eventual production stages.
STM targets training, patrol, and light air support
Although there is still no public data on engine, autonomy, payload, avionics, or armaments, the concept of a multipurpose aircraft indicates a flexible platform aimed at advanced training, patrolling, surveillance, liaison, observation, and support for lower-cost operations.
For this profile, the future STM appears in the same segment of military turboprops used by various countries, such as the Brazilian A-29 Super Tucano and the American T-6 Texan II, both associated with training and light operational missions.
The comparison, however, requires caution, because the Chilean project has not yet presented performance, final configuration, or a public production schedule, which prevents claiming operational equivalence with foreign models already in service.
At the current stage, the focus is on designing a national solution for common needs of the Navy and Air Force, using infrastructure, specialized labor, and knowledge accumulated by ENAER in previous programs.
T-40 Newen enters the context of the new program
The STM emerges after the presentation of the T-40 Newen, a training aircraft developed by ENAER and officially showcased during FIDAE 2026, an aerospace fair held in Chile focused on the civil aviation, defense, and technology sectors.
According to the FIDAE organization, the Newen was presented on April 8, 2026, as an integrated training system, bringing together aircraft, digital avionics, advanced simulation, and national industrial capabilities.
The aircraft was designed to replace the fleet of the T-35 Pillán, a trainer used for over four decades in the training of pilots in Chile and associated countries, according to information released during the fair.
Also according to FIDAE, the T-40 Newen features a glass cockpit, integrated flight management system, advanced tactical navigation, and certification for military aerobatics, in addition to a configuration aimed at training, surveillance, and longer-duration reconnaissance.
This development helps contextualize the creation of the STM, as Chile begins to study a multipurpose turboprop aircraft with greater institutional reach, but still dependent on technical stages and investment decisions.
ENAER seeks to apply experience in new project
ENAER arrives at the STM with experience in manufacturing, maintenance, and modernization of aircraft, in addition to the accumulated experience with the T-35 Pillán, a model frequently cited as a reference in the Chilean aeronautical industry.
The number of more than 140 aircraft produced is associated with the Pillán’s trajectory, but it is not detailed in the public sources used to support the information verified in this edition.
Even with this caveat, the role of the state-owned company in the new program is relevant within the announced structure, because the study of the STM involves the ability to transform national engineering into a viable military product, with local maintenance and control over critical systems.
During the presentation of the T-40 Newen, Henry Cleveland stated that Chile decided to develop an aircraft with modern technology, designed and manufactured in the country itself, in addition to mentioning a study for a turboprop aircraft with greater performance than the Newen.
The statement links the trainer’s advancement to the new multipurpose program, although the two projects have their own objectives and depend on distinct stages before any decision on serial production or operational incorporation.
Defense, industry, and technical training in the same program
Chile’s interest in the STM goes beyond the replacement or expansion of military aircraft, as the program also involves local chains of engineering, advanced manufacturing, systems integration, embedded software, simulation, and specialized maintenance.
At the signing of the agreement, Vice Admiral César Delgado linked the project to the strengthening of the national industry, while Cleveland stated that the strategic defense industry plays a relevant role in the technological development of the country.
If it advances to development and production, the manufacturing of a modern military aircraft in Chile would increase the country’s presence among Latin American nations with the capability to design their own platforms, but this scenario depends on the newly initiated study.
At the moment, the STM brings together technological autonomy, operational standardization, and the utilization of the knowledge created by the T-40 Newen, without public confirmation regarding orders, exports, total costs, production schedule, or entry into service.
