I wont accept anyones sonar being better then the Americans. Because technology isn't acquired out of thin air. It takes experience and it's a process of learning...i.e the technology tree and how much capital you pump into R&D. Yes, China can make a jet fighter...and a good one...but one to match an F-22?

The US has been playing with Sonar against the Soviets in real combat situations (i.e. not a lab or sim) for nigh on half a decade. Now, historically nuetral Sweden has better Sonar technology then the Americans?

Maybe made by Ikea to boot.
