There is no significant information regarding the tanker fleet and the transport fleet, although we know that most of the He-76 transport aircraft and also the IRIAF's Reg-707 reconnaissance and electronic warfare aircraft were destroyed. The IRIAF Kg-33A fleet, which was a Boeing 747-derived tanker and the largest tanker in the world, was also said to have been lost. Several C-130s were also destroyed. In the Navy, most of the Stallion and Sea King fleets and the entire P-3 Orion maritime patrol fleet appear to have been lost.
