Taiwan's aerospace maker AIDC just finished delivering its home-built trainer jet fleet and is pivoting to long-term maintenance work worth billions — good news for Taiwan's defense industry and its push to build weapons at home.

• AIDC handed over the last two Brave Eagle advanced trainer jets to the air force, completing all 66 aircraft seven years after the first one rolled out.
• Maintenance and spare-parts contracts for the Brave Eagle and the older IDF fighter are expected to top NT$30 billion.
• Company leadership says the focus now shifts to keeping the fleet flying, under full life-cycle service deals already underway.
• Drones are reshaping warfare, and AIDC plans to pour resources into unmanned aircraft in line with the defense ministry's priorities.
• One Brave Eagle was lost in a crash, cutting the fleet to 65; AIDC says its tooling is preserved and it could restart production if ordered.

Outlook: Expect AIDC's revenue to lean more on servicing existing jets and on drone development, with a possible replacement order still pending a government decision.
