Taiwan's parliament is heading for a showdown vote over how to fund a major military drone buildup, a fight that pits the defense ministry against the opposition and leaves the country's drone industry waiting on orders.

• Talks between the ruling DPP and the opposition KMT and TPP collapsed, so the speaker sent competing bills straight to a floor vote with all parties calling in every lawmaker.
• The cabinet wants a special six-year budget of about NT$210 billion aimed narrowly at three types of naval drones, run by the defense ministry.
• The opposition wants a bigger pot spread over normal annual budgets, with the economics ministry in charge and a much looser definition of what counts as a drone.
• Defense minister Wellington Koo says the loose definition would swallow the money on existing purchases like US-made MQ-9B aircraft, leaving little for the weapons the military actually needs.
• Officials warn annual budgeting invites cuts and delays, and drone makers say what they need most is predictable orders before they invest.

Outlook: The floor vote will decide which version wins, and with the opposition holding the numbers the government's version faces an uphill fight.
