A Congressional Research Service report puts U.S. aircraft losses and damage in the war with Iran at 81 airframes, worth between $1.9 billion and $3.3 billion. MQ-9 Reapers account for over half. An F-35, an E-3 Sentry and eight lightly damaged F-15s are also on the list. Total war costs stand at a minimum of $45 billion, not counting damage to American bases in the region.
