NASA & Subs and a Submarine in a Wind Tunnel

The Navy submarine pictured in this image underwent testing in the National Transonic Facility at Langley Research Center in this 1986 photo. Because air works in the same way as a liquid, wind tunnels can be used to simulate the effects of water on a submarine hull.
