Description
Frank Heinemann is a character from Muv-Luv Alternative: Total Eclipse. He serves as a technical manager dispatched from Boening, an American defense contractor, to participate in the XFJ Project, a joint development program with Japan based out of the Yukon Base in Alaska.

In terms of background, Heinemann is an exceptionally experienced and brilliant aeronautical engineer. Prior to his tenure at Boening, his career included producing the F-14 Tomcat at Grumman and later participating in the development of the YF-23 Black Widow II. He was also involved with Japan's Dawn Plan, where he was responsible for technical training for dispatched instructors. This history has given him a comprehensive and rare perspective on tactical surface fighter development across multiple leading American manufacturers.

Heinemann's personality is marked by a sharp, incisive intellect and a pragmatic, often cynical view of military and corporate politics. He is a straightforward speaker, unafraid to silence investigators with brilliant and logical arguments, as demonstrated when the Argos platoon came under suspicion of a technology leak. He possesses a deep, almost personal connection to his work, viewing tactical aircraft design as both a science and an art. Beneath his gruff professional exterior, there are layers of history and personal regret. At the end of the story, he reflects on past photographs of himself with close friends Mira Bridges, Eiji Iwaya, and Masatada Takamura, revealing buried feelings of jealousy and complaint. He had a crush on Mira but was not chosen by her, and he harbored some resentment toward Masatada for that reason.

His role in the narrative is that of a critical supporter and mentor figure to the younger pilots and engineers, particularly to the protagonist Yuuya Bridges, whose mother, Mira, was an old friend of Heinemann. While his presence is less pronounced in the anime adaptation, the visual novel elevates his importance significantly, positioning him almost as a secondary protagonist. He is a central figure in the game's second half, where his history and motivations are explored more deeply. During the terrorist incident by the Refugee Liberation Front, his actions were suspicious as he vacated the Yukon Base with Hartwick, hinting at a more complex agenda or knowledge of unfolding events.

Key relationships define much of his personal history. His friendship with Eiji Iwaya and Masatada Takamura from their younger days, as well as his unrequited feelings for Mira Bridges, are foundational to his character. These past connections directly influence his decision to participate in the XFJ Project, which is a collaboration between Japanese and American entities.

In terms of development, Heinemann is portrayed as a static character whose core beliefs are tested but remain unbroken. He endures an investigation into technology leaks with a masterful defense of his engineering choices, arguing that the visual similarity between the Shiranui Second and the YF-23 stems from identical performance requirements, not espionage. Ultimately, he is a figure of tragic professional disappointment. He witnesses the YF-23 he helped create become unfairly evaluated and eventually dismissed as the most expensive scrap metal. In contrast, he sees inferior machines like the Su-27 and Su-37 find success, which embitters his view of the military-industrial complex.

Frank Heinemanns most notable abilities lie not on the battlefield, but in the realm of engineering and technical strategy. He is a genius-level developer, often compared to Mikhail Kalashnikov within the Muv-Luv universe for his profound impact on tactical machine design. His deep understanding of aerodynamics, stealth technology, and electronics allows him to solve complex engineering problems and guide the development of next-generation TSFs. His ability to verbally outmaneuver US military investigators with technical and logical arguments further proves his formidable intellect and deep understanding of the systems he creates.
