Princess Leonor de Borbón, Princess of Asturias, officially completed her three-year military training on July 10, 2026 [1].

As the heir to the Spanish throne, this training is a prerequisite for Leonor to eventually assume the role of Supreme Commander of the Armed Forces [1]. The completion of these requirements marks a critical step in her preparation for future sovereign responsibilities.

The ceremony took place at the Academia General del Aire, also known as the Air Academy, in San Javier, Región de Murcia [1], [2], [3]. During the event, King Felipe VI presented his daughter with her officer commission and the Grand Cross of the Aeronautical Merit [1], [2].

Leonor's military education spanned three years, beginning in August 2023 and concluding in July 2026 [1]. The curriculum provided the princess with foundational training across different branches of the military to ensure a comprehensive understanding of national defense.

Reflecting on the personal impact of the rigorous program, the princess spoke about her growth during the process. "No soy la misma persona" — I am not the same person, she said [4].

While reports on the specific rank of the officer commission vary between a lieutenant and an ensign, the event served as the formal culmination of her instructional period [1], [2]. The presence of the King at the San Javier academy emphasized the institutional importance of the princess's transition to a commissioned officer.

“"No soy la misma persona"”

The completion of this training reinforces the traditional link between the Spanish monarchy and the military. By fulfilling these requirements, Princess Leonor secures the legitimacy needed to lead the armed forces upon her eventual accession, signaling stability and continuity in the Spanish state's command structure.
