Engine question

A few questions

1. What engine gives the highest thrust on any aircraft in use today? (F135??)
1. Does the YF-23 BLACK WIDOW II really have a thrust to weight ratio of 1.81 or is that a typo on wikipedia?

The GE-90-115B on the Boeing 777-300R is listed at a thrust of 115,000 pounds on take off. Remember having a high trust engine doesn't mean a plane has to be "High- Preformance". If it's a large aircraft, it will require a lot of thrust to fly.

For the Record, the J-58 used on the SR-71 Blackbird has a maximum thrust of 32,500 lbs. in full afterburner. Just goes to show that engine thrust alone isn't what makes an airplane fast!

In terms of fighter aircraft, which I presume was what the OP meant the F135 is currently the most (acknowledged) powerful engine with 43,000 lb in afterburner and 28,000 lb in mil power.

Also, that article on Wiki about the YF-23 is wrong, their figures are wrong and if they even bothered to do the math with the figures they have listed the T/W ratio would be more like 1.36/1
