WASHINGTON, March 20 (Reuters) – A U.S.-led defense manufacturing partnership agreed to launch a new missile motor production program with Japan, push forward a drone ​cooperation effort across Asia and explore building a ‌new ammunition production line in the Philippines, the Pentagon said on Friday.

The Partnership for Indo-Pacific Industrial Resilience, known as PIPIR, is a group of nations working together to build up their weapons and defense ‌manufacturing ​capacity in the Asia-Pacific region. The United ⁠States set it up ⁠in May 2024 to reduce supply chain risks and help allies produce and maintain military equipment closer to where it might be needed.

The Pentagon published a joint statement ​following a virtual meeting on Wednesday, where the group welcomed two new members — Thailand and the United Kingdom — ⁠bringing its total membership to 16 ⁠countries spanning both the Indo-Pacific and Europe.

The group ​said it had agreed to set up a new program ​to produce solid rocket motors — the propulsion systems used ‌in many guided weapons — with Japan taking the lead. The move is seen as a way to boost production capacity outside the United States for a key weapons component.

On ⁠drones, members agreed on a series of steps to develop common standards and shared supply chains for small military drones across the ⁠region, including work ‌on batteries and small motors that power ⁠them. The group also agreed to explore ​building ‌drones together across a range of military ​uses.

On ammunition, members ⁠said they would look into the Philippines hosting a new facility to load, assemble, and package 30mm cannon rounds — a type of ammunition widely used by military aircraft and ground vehicles.
