BAE systems, which currently employs 1,200 people in Portsmouth and 3,200 across Govan, Scotstoun, Rosyth, and Filton plans to cut 1,775 jobs in England and Scotland.
The company also plans to end shipbuilding altogether at Portsmouth following a significant drop in demand.
A statement released by BAE Systems said: "Under these proposals, shipbuilding operations at Portsmouth will cease in the second half of 2014.
"Subject to consultation, Lower Block 05 and Upper Blocks 07 and 14 of the second Queen Elizabeth Class Aircraft Carrier will be allocated to Glasgow.
"The company remains committed to continued investment in the Portsmouth area as the centre of its Maritime Services and high-end naval equipment and combat systems business."
BAE said it had agreed with the MoD "that Glasgow would be the most effective location for the manufacture of the future Type 26 ships".
The statement added: "The implementation of these restructuring activities will sustain BAE Systems' capability to deliver complex warships for the Royal Navy and secure the employment of thousands of highly skilled employees across the UK."
