With an improved drivetrain, a reinforced airframe and enhanced fuel system, the CH-47F Block II provides for an additional 4,000 pounds of max gross weight and extends the mission radius for nearly all payloads. In addition to the capability improvements, the aircraft’s design enables future technology upgrades.
“As the Army’s Heavy Lift platform of tomorrow, the CH-47F Block II provides increased capability while continuing support of the Army's requirement to remain strategically responsive across the full spectrum of operations,” said Viva Kelly, U.S. Army Cargo Helicopters acting project manager.
Additionally, the company’s Block II program improves aircraft sustainment. The improved reliability of the new rotor system minimizes unscheduled maintenance, and the simplified fuel system drives sustainment efficiency reducing maintenance burden and cost.

Im curious what the redesign of the rotor system means. They abandoned the Advanced Composite Rotorblade because of excessive vibration a couple years ago.
I wonder if it’s simply switching from 555 oil to gear oil in the heads. I remember a test of this back in the 2008 time frame in our fleet, Columbia Helicopters came out and helped install different seals in 6 rotor heads and those aircraft flew into 400 hour phase maintenance.
It did result in significantly less unscheduled maintenance, as in we didn’t touch those heads for anything other than scheduled maintenance dining that whole period, but at the end of the test if memory serves, the Army saw some increase in wear on the Horizontal Hinge Pin thrust washers after and didn’t switch over to the heavier oil.
Be interesting to see how it goes in the end. People don’t believe me when I say I didn’t mind working on Chinooks….🤣
