Would a submarine survive an asteroid?

The ocean could be affected by high tsunami and/or pressure waves in the case of a large asteroid or comet impact. Most current submarines can survive at a depth of 400 m, so they might survive long pressure spikes created by the waves above them as high as 200–400 m, but not kilometer size waves.
