It is thought that Euro RSCG, which held the £200,000 consumer account prior to the repitch, has won the major part of the brief against pitches from Consolidated PR, The Red Consultancy and Fishburn Hedges.
However, it is understood that BAE also plans to bring in Mischief PR to handle a more creative aspect of its consumer comms.
BAE head of external comms Kate Watcham confirmed the company was in talks with the two agencies, but said that no appointments had yet been finalised.
Speaking about the brief, Watcham previously said the firm was ‘looking for an agency that can support us with communicating our engineering and technology and innovation expertise.'
Euro RSCG and Mischief both declined to comment.
BAE Systems is a member of the FTSE 100 and has operations across the globe developing defence, security and aerospace systems.
In January, Euro RSCG announced that BAE Systems had successfully demonstrated a prototype laser device to serve as a non-lethal deterrent against pirate attacks on oil tankers and container ships.
