TOKYO, Dec 6 (Reuters) – Japan, Britain and Italy will sign a treaty in Tokyo next week to establish a joint organisation and industry group for developing their planned advanced jet fighter, three sources with direct knowledge of the plans said.

An inter-government body will oversee the industry group venture led by Britain’s BAE Systems PLC, Japan’s Mitsubishi Heavy Industries and Italy’s Leonardo. That group will distribute work to teams in different parts of the Global Combat Air Programme (GCAP), such as the engine and avionics, the sources said.

They asked not to be identified because they are not authorised to speak to the media.

Reuters in March reported that Japan and Britain would dominate GCAP, with about a 40% share of the work each. Rome dismissed that as “speculative”.

Japan’s defence ministry declined to comment. Officials at the British and Italian embassies did not immediately respond to requests for comment.

The agreement, which parliaments of each country must ratify, will come a year after they established their first major defence industry collaboration by merging the separate next-generation fighter efforts of London and Tokyo.

Someone from Japan may lead the project initially, and the management will rotate among the three countries, two of the sources said. Japan’s leading candidate for that job is Masami Oka, and adviser to the defence ministry who retired as vice minister of international affairs in July, they added.

Oka did not immediately respond to a request for comment.
