When the F-105 Thunderchief™ entered service in 1958,
it was the heaviest single-engine combat aircraft.
Today, the F-105 remains history's heftiest fighter, weighing close to 50,000 pounds (23,000 kg). It also packed a heavy punch-up to 14,000 lb of ordnance. Despite its weight, the F-105 could still achieve Mach 2 speeds.
The Thunderstick II variant was equipped with and upgraded radar and target acquisition set that allowed it to bomb from 15,000 feet with incredible accuracy
