An SH3 is referring to a SH-3 Sea King. The Navy used to use them as their submarine hunter/killers. It can be equipped with all sorts of awesome toys like depth charges, torpedos, hell you can even strap a nuke to the thing if you so desire. Primarily though, it dropped sonobuoys and sonar cables to assist with submarine detection. It got phased out in the 90s in favor of the Seahawk because of the SH-60s versatility and I believe now they use the Sea King as the US Presidents helicopter.
