What is known about the reported damage to Iran's military and its remaining capabilities

Iranian and US officials are engaged in mediated negotiations in Doha following the signing of a memorandum of understanding on 17 June aimed at ending a war that began in February, according to information provided on the conflict and its aftermath.

The talks come after months of fighting that caused extensive damage to Iran's military assets and civilian infrastructure, while leaving parts of the country's strategic and asymmetric capabilities intact, says Al Jazeera.

The conflict involved sustained aerial campaigns, with US forces striking more than 13,000 targets and Israel carrying out approximately 4,000 strikes, according to the information provided.

US Central Command reported that more than 85% of Iran's ballistic missile, drone and naval defence-industrial base had been damaged or destroyed. The affected facilities included sites involved in the production of propellant motors and precision-targeting systems.

Iran's naval and air forces also suffered extensive losses. More than 155 vessels were reported damaged or destroyed, including the warship IRIS Dena, while much of Iran's ageing fleet of fighter aircraft, helicopters and refuelling planes was lost.

Israel said it had destroyed 250 air defence systems and 60% of Iran's missile launchers, and claimed "aerial superiority" over Tehran.

Strikes also hit civilian infrastructure including oil and gas facilities, power plants and water systems. Israel reported destroying 70% of Iran's steel production capacity and rendering 85% of its petrochemical export capacity inoperable.

A US naval blockade from April through June also sharply reduced oil exports and intensified inflationary pressures inside Iran, according to the information provided.

Despite the reported damage, Iran has retained elements of its military posture and has moved to restore some capabilities.

Large sections of Iran's underground missile networks, built deep into mountainous terrain, remained intact during the conflict, with activity reportedly returning to nearly 90% of those facilities.

Drone manufacturing has also resumed in some areas after production sites were struck. Army commanders said output had "increased tenfold" since an earlier 12-day conflict with Israel.

Iran also introduced a new air defence system known as Arash-e Kamangir, which reportedly shot down a US MQ-9 Reaper drone. Other systems reportedly achieved partial interceptions against advanced aircraft including the F-35 and F-15E.

Although larger naval assets were destroyed, Iran's Islamic Revolutionary Guard Corps has continued to rely on fast boats and projectile systems in the Strait of Hormuz, according to the information provided. The force was reported to have recently stopped commercial vessels using US-backed routes.

The conflict also reshaped Iran's political landscape.

Former Supreme Leader Ali Khamenei was killed at the outset of the war on 28 Feb., according to the information provided. His son, Mojtaba Khamenei, was selected as his successor but has not appeared publicly and was reportedly "marked for death" by Israel.

Questions also remain over Iran's nuclear programme. Highly enriched uranium buried beneath bombed facilities is believed to be recoverable, although extraction could take considerable time and may depend on future agreements.

Tensions persist despite the negotiations.

Israel remains opposed to the current talks and has identified targets for possible renewed military operations, according to the information provided. Iran's leadership has vowed an "immediate powerful response" to any threats against its people or leaders.
