I just read where Russian Su-30 engines are intended to operate 300 hours
before major overhaul. How do US engines compare? 300 hours seems
awfully
short to a layperson like me.

I can only speak to our J-75s, but it was teardown inspection and repair
every 400 hours; depo overhaul each 1200 hours.
