Qatar intends to acquire a total of 24 Typhoon and six Hawk aircraft from the UK firm.
In September, Qatar Defence Minister Khalid bin Mohammed al Attiyah signed a Statement of Intent (SoI) with the then-UK Defence Secretary Michael Fallon to purchase Typhoon multi-role combat aircraft.
The SoI could further strengthen military cooperation between the two countries and provide an opportunity to further enhance the security of all partners in the Gulf Cooperation Council (GCC).
In a statement to the British Parliament’s Defence Select Committee, BAE Systems UK Military Air and Information managing director Chris Boardman said: “We would not like to speculate on the exact date when it will be signed.
“We have concluded all our discussions, so we have no more negotiation to do with the Qataris. The contract is done. It is sealed.
“We understand what that is going to be. They think it is a good deal, and we think it is a good deal, so it is good to move on from that point.
“It is purely down now to when there is the right window to have that signed.”
The Typhoon multi-role combat aircraft is said to have long-term potential to be at the forefront of air power for many years.
The Kuwait Ministry of Defence (MoD) has also committed to investing in 28 Typhoons, which will be delivered over the next few years.
The UK would also provide Hawk training aircraft to Kuwait to supplement the Typhoon commitment.
1,000 Hawks are currently available across 18 countries.
As part of its restructuring, BAE Systems is planning to cut 1,915 jobs in the UK.
