4,000 more hours in the sky
The Block II Super Hornets in operation for the U.S. Navy today are each rated for 6,000 flight hours, so it goes without saying that the past two straight decades of combat operations in the Middle East and elsewhere have wrought havoc on maintenance schedules and aircraft availability. In another one of those significant changes that are tough to spot with the naked eye, the Block III Super Hornet is rated for an additional 4,000 hours, bringing the total up to 10,000.
This is still a far cry from the F-15EX’s reported lifespan of 20,000 hours, but offers a significant jump over both existing F/A-18s and the F-35C, which is also rated for 6,000 hours.
This longer lifespan will make the new Block III Super Hornet a most cost-effective means of delivering air power than ever before, while also offering the Navy itself greater latitude in logistical planning.
Bonus Improvement: Infrared Search Track System
Technically not considered a “Block III” improvement, the addition of a centerline tank-mounted infrared search track system (IRST) in the Block III Super Hornet has been called “integral” for the capability of the fighter by Boeing officials.
This passive detection capability is aimed squarely at fifth-generation competitors like Russia’s Sukhoi Su-57 or China’s Chengdu J-20. The IRST can be used to scan the horizon for radar-beating fighters, picking up on the infrared heat released by their jet engines without broadcasting a signal through space to tell others you’re on the hunt. This will give the non-stealth Block III Super Hornet a real fighting chance against stealthy jets, potentially spotting them against the sky backdrop from a hundred miles away.
