Aircraft over central PA

[york2]

I saw 3 dark gray military transport planes around noon time over Harrisburg. They were not C-130's and I can't figure out what they are. All were the same type with one jet engine per wing, high rear horizontal stabilizer and winglets. Any ideas?

Thanks. Thought they only had one engine per wing, but I really couldn't tell while driving.
