The "victory" was scored in military exercises involving the US navy versus the ultra-quiet swedish diesel-electric sub Gotland, where the sub has now successfully eluded capture for two months (out of a full year of planned exercises).
Gotland employs an advanced and basically vibration-free stirling engine fuelled by diesel and liquid oxygen to generate power in submerged mode, and this gives the boat very long stamina under water. Unlike conventional diesel-electric subs, it does not have to rely on battery power and air stored in tanks; it can generate new fresh oxygen like a nuclear sub and stay under water for weeks at a time, if not more. Also, not being nuclear powered, it means it won't have lots of pumps and turbines spinning, creating lots of noise.
Cool stuffs! Also, lending our submarine for this exercise means lots of US taxpayer dollars finding their way into our coffers, heh heh. Good for our country.
