The United States Navy submarine tender USS Frank Cable (AS-40) and its more than 500 sailors and civilian personnel aboard now officially have luck on their side.

In the following video, you’ll witness — as did the vessel’s military crew — dolphins jumping off the coast of Guam, where the sub tender launched from just the other day for the first time in 14 years.

To sailors and mariners alike, the aquatic mammals dancing as they do between the whitecaps is the most promising and positive of omens.

The vessel is 40 years old and offers repair and maintenance, logistical support for nuclear attack submarines and deployed naval forces. According to the source of the video, it’s currently heading to the Indo-Asia-Pacific region.
