What are the GCC’s air defence capabilities?

The Gulf Cooperation Council’s (GCC) Joint Defence Council held an emergency session in Doha, Qatar, on Thursday, to discuss urgent regional security measures in response to the recent Israeli strike on a Hamas office in Qatar’s capital, which killed six people.
GCC Secretary-General Jasem Mohamed AlBudaiwi said the attack on the State of Qatar can be considered an attack on all GCC countries.
AlBudaiwi said member states would activate joint defence mechanisms, enhance intelligence sharing, coordinate aerial positions, activate an early-warning system against ballistic missiles and carry out joint training exercises, including a regional air force drill.
Qatar is the seventh country Israel has bombed since the start of this year.
Which countries make up the GCC, and what do they spend on their militaries?
The Gulf Cooperation Council (GCC) is a political and economic bloc which was formed in 1981. It brings together six Arab states on the Arabian Peninsula:
Bahrain
Kuwait
Oman
Qatar
Saudi Arabia
United Arab Emirates (UAE)
The GCC was established to promote cooperation on security, economics and politics, and it often coordinates positions on regional and international issues.
In 2023, GCC countries collectively spent $114.5bn on their militaries. Saudi Arabia accounted for the largest share, budgeting for at least $69bn and ranking as the world’s seventh-largest military spender, followed by the United Arab Emirates (UAE) at $20.7bn, Qatar at $9.02bn, Kuwait at $7.77bn, Oman at $6.5bn and Bahrain at $1.4bn, according to the International Institute for Strategic Studies, Military Balance 2024.
