Unions have vowed to fight plans to cut hundreds of jobs in Portsmouth.
They will meet with senior executives from BAE Systems next week to discuss the loss of 940 jobs at the Portsmouth ship yard.
Shipbuilding will cease in the city from 2014.
Overall, 1,775 jobs will go at BAE Systems in Scotland and Portsmouth.
1800 jobs will be cut in shipyards operated by BAE Systems across England and Wales, bringing shipbuilding in Portsmouth to an end.
Unions are to meet defence giant BAe Systems to discuss the future of the firm's three shipyards amid a review of its business.
