Iran has showed off a sprawling underground network of tunnels filled with row after row of drones and rockets, amid fears the US and its allies are burning through expensive weaponry in their war against the regime.
Footage released by the Fars News Agency, which is closely linked to the Islamic Revolutionary Guard Corps, shows long lines of missiles and Shahed drones.
With a ticking clock playing in the background, the video used dramatic drone footage to show off the extent of their cheap arsenal.
One shot appeared to show a wall-to-wall hanging depicting the now-dead Supreme Leader Ali Khamenei looking out over the massive arsenal of drones.
A series of Iranian flags were seen hanging down from the roof of the tunnels.
Another showed a pair of lorries carrying Shahed drone launchers, each one holding four of the cheap drones.
Shahed drones cost just tens of thousands of dollars to produce, and take little time to manufacture.
As war continues to rage on, there are now fears that the sophisticated weaponry favoured by the US and its allies may be too expensive and too hard to procure for a longer military campaign.
Israel today admitted that Iran still has significant capacity to fire missiles at its enemies.
American-made Patriot missiles can cost between $4-5million (£3-3.75million), with export prices being even higher.
THAAD missile batteries, meanwhile, can cost around $13million (£9.74million) each.
Analysis carried out by Kirsty Grieco, a security expert at the Stimson Centre in Washington DC, found that the UAE had shot down 92 per cent of the missiles and drones Iran's slung its way.
Grieco estimates Iran spent in the region of $11million to $27million on the 541 drones it launched on the UAE, with interceptors averaging $500,000-$1.5million per drone to shoot down 506 of them.
The UAE's drone defence costs were between $253million and $759million, suggesting it spent up to 30 times more defending itself against Iran's drones than its adversary spent on attacking it.
