 On 25 January 1999, six companies were invited to tender for the assessment phase of the project – Boeing, British Aerospace, Lockheed Martin, Marconi Electronic Systems, Raytheon and Thomson-CSF. On 23 November 1999, the Ministry of Defence (MoD) awarded detailed assessment studies to two consortia, one led by BAe (renamed BAE Systems on 30 November 1999) and one led by Thomson-CSF (renamed Thales Group in 2000). The brief required up to six designs from each consortium with air-groups of thirty to forty Future Joint Combat Aircraft (FJCA). The contracts were split into phases; the first £ 5.9 million phase was for design assessment which would form part of the aircraft selection, while the second £ 23.5 million phase involved "risk reduction on the preferred carrier design option."
