Question for the Sailors...

[82Rigger]

...I saw an emblem sticker on the rear window of a car today, and am wondering if it signifies something Navy.

On a black background, a gold eagle with outstretched wings. The eagle is looking down and to the viewer's left. The eagle is on top of a vertical gold anchor. Across the center of the anchor is a horizontal trident, i.e. like "Neptune's trident" with the three tines of the trident to the right.

If it has any significance, also on the car's bumper was a different sticker....a red flag with white diagonal bar, which I understand to be the flag ships and boats fly when they have a diver in the water.

Any ideas on the black & gold emblem?
