The Joint Ground Based Air Defence Headquarters or JtGBAD HQ was a joint (non-deployable), force-generating British military formation under the operational command of RAF Air Command, sitting under No.1 Group. It was formed circa 2000 and disbanded in 2019 in favour of 7th Air Defence Group.
All of the organisation's subordinate units were drawn from the British Army's Royal Regiment of Artillery and 90% of its HQ staff, including its commander (a colonel), were tied Royal Regiment of Artillery posts. As most of the formation's personnel and equipment were Army, as were most of its outputs, the formation came under the British Army's Force Troops Command for budgetary and coordination purposes, although there was no command relationship with this organisation.
Jt GBAD commanded all the Ground Based Air Defence (surface-to-air) units in the United Kingdom's Armed Forces, with the exception of the Air Defence Troop Royal Marines who are part of No 30 Commando Royal Marines under the operational command of the Royal Navy, sitting under 3 Commando Brigade Royal Marines.
